Exclusion criteria in the searches included (1) non-empiric health policy journal articles (e.g., conceptual articles, editorials); (2) narrative and systematic reviews; (3) studies with only qualitative assessment of health policy implementation; (4) empiric studies reported in theses and books; (5) health policy studies that only assessed health outcomes (i.e., target population changes in health behavior or status); (6) bill analyses, stakeholder perceptions assessed to inform policy development, and policy content analyses without implementation assessment; (7) studies of changes made in a private business not encouraged by public policy; and (8) countries with authoritarian regimes. We electronically programmed the searches to exclude policy implementation studies from countries that are not democratically governed due to vast differences in policy environments and implementation factors.
Citations were downloaded into EndNote version 7.8 and de-duplicated electronically. We conducted dual independent screening of titles and abstracts after two group pilot screening sessions in which we clarified inclusion and exclusion criteria and screening procedures. Abstract screeners used Covidence systematic review software [ 40 ] to code inclusion as yes or no. Articles were included in full-text review if one screener coded it as meeting the inclusion criteria. Full-text screening via dual independent screening was coded in Covidence [ 40 ], with weekly meetings to reach consensus on inclusion/exclusion discrepancies. Screeners also coded one of the pre-identified reasons for exclusion.
Extraction elements included information about (1) measure meta-data (e.g., measure name, total number of items, number of transferable items) and studies (e.g., policy topic, country, setting), (2) development and testing of the measure, (3) implementation outcomes and determinants assessed (Table (Table2), 2 ), (4) pragmatic characteristics, and (5) psychometric properties. Where needed, authors were emailed to obtain the full measure and measure development information. Two coauthors (MP, CWB) reached consensus on extraction elements. For each included measure, a primary extractor conducted initial entries and coding. Due to time and staff limitations in the 12-month study, we did not search for each empirical use of the measure. A secondary extractor checked the entries, noting any discrepancies for discussion in consensus meetings. Multiple measures in a study were extracted separately.
To assess the quality of measures, we applied the Psychometric and Pragmatic Evidence Rating Scales (PAPERS) developed by Lewis et al. [ 10 , 11 , 41 , 42 ]. PAPERS includes assessment of five pragmatic instrument characteristics that affect the level of ease or difficulty to use the instrument: brevity (number of items), simplicity of language (readability level), cost (whether it is freely available), training burden (extent of data collection training needed), and analysis burden (ease or difficulty of interpretation of scoring and results). Lewis and colleagues developed the pragmatic domains and rating scales with stakeholder and D&I researchers input [ 11 , 41 , 42 ] and developed the psychometric rating scales in collaboration with D&I researchers [ 10 , 11 , 43 ]. The psychometric rating scale has nine properties (Table (Table3): 3 ): internal consistency; norms; responsiveness; convergent, discriminant, and known-groups construct validity; predictive and concurrent criterion validity; and structural validity. In both the pragmatic and psychometric scales, reported evidence for each domain is scored from poor (− 1), none/not reported (0), minimal/emerging (1), adequate (2), good (3), or excellent (4). Higher values are indicative of more desirable pragmatic characteristics (e.g., fewer items, freely available, scoring instructions, and interpretations provided) and stronger evidence of psychometric properties (e.g., adequate to excellent reliability and validity) (Supplemental Tables 4 and 5 ).
Psychometric and Pragmatic Evidence Rating Scale (PAPERS) domains and definitions
Scale | Domain | Definition |
---|---|---|
Pragmatic criteria | Brevity | Number of items; excellent < 10 items |
Language simplicity | Readability of items, ranging from accessible only to experts (poor) to readable at or below an 8th grade level (excellent) | |
Cost to use instrument | Monetary amount researchers pay to use the instrument; excellent = freely available in the public domain | |
Training ease | Extent of assessor burden due to required trainings versus manualized self-training; excellent = no training required by instrument developer | |
Analysis ease | Extent of assessor burden due to complexity of scoring interpretation; excellent = cutoff scores with value labels and automated calculations | |
Psychometric properties | Norms | A measure of generalizability based on sample size and means and standard deviations of item values |
Internal consistency | Reliability | |
Convergent construct validity | Observed association in data of two theoretically related constructs, assessed through effect sizes and correlations | |
Discriminant construct validity | Observed differentiation (lack of association) of two theoretically distinct constructs, assessed through effect sizes and correlations | |
Known-groups validity | Extent to which groups known to have different characteristics can be differentiated by the measure | |
Predictive criterion validity | Extent to which a measure can predict or be associated with an outcome measured at a future time | |
Concurrent criterion validity | Correlation of a measure’s observed scores with scores from a previously established measure of the construct | |
Responsiveness | Extent to which a measure can detect changes over time, i.e., clinically important not just statistically significant changes over time | |
Structural validity | Structure of test covariance, i.e., extent to which groups of items increase or decrease together versus a different pattern, assessed by goodness of fit of factor analyses or principal component analyses |

This section describes the synthesis of measure transferability, empiric use study settings and policy topics, and PAPERS scoring. Two coauthors (MP, CWB) consensus coded measures into three categories of item transferability based on quartile item transferability percentages: mostly transferable (≥ 75% of items deemed transferable), partially transferable (25–74% of items deemed transferable), and setting-specific (< 25% of items deemed transferable). Items were deemed transferable if no wording changes or only a change in the referent (e.g., policy title or topic) was needed to make the item applicable to the implementation of other policies or in other settings. Abstractors coded study settings into one of five categories: hospital or outpatient clinics; mental or behavioral health facilities; healthcare cost, access, or quality; schools; community; and multiple. Abstractors also coded policy topics to healthcare cost, access, or quality; mental or behavioral health; infectious or chronic diseases; and other, while retaining documentation of subtopics such as tobacco, physical activity, and nutrition. Pragmatic scores were totaled for the five properties, with possible total scores of − 5 to 20, with higher values indicating greater ease to use the instrument. Psychometric property total scores for the nine properties were also calculated, with possible scores of − 9 to 36, with higher values indicating evidence of multiple types of validity.
The database searches yielded 11,684 articles, of which 3267 were duplicates (Fig. (Fig.1). 1 ). Titles and abstracts of the 8417 articles were independently screened by two team members; 870 (10.3%) were selected for full-text screening by at least one screener. Of the 870 studies, 804 were excluded at full-text screening or during extraction attempts with the consensus of two coauthors; 66 studies were included. Two coauthors (MP, CWB) reached consensus on extraction and coding of information on 70 unique quantitative eligible measures identified in the 66 included studies plus measure development articles where obtained. Nine measures were used in more than one included study. Detailed information on identified measures is publicly available at https://www.health-policy-measures.org/ .
PRISMA flow diagram
The most common exclusion reason was lack of transferable items in quantitative measures of policy implementation ( n = 597) (Fig. (Fig.1). 1 ). While this review focused on transferable measures across any health issue or setting, researchers addressing specific health policies or settings may find the excluded studies of interest. The frequencies of the remaining exclusion reasons are listed in Fig. Fig.1 1 .
A variety of health policy topics and settings from over two dozen countries were found in the database searches. For example, the searches identified quantitative and mixed methods implementation studies of legislation (such as tobacco smoking bans), regulations (such as food/menu labeling requirements), governmental policies that mandated specific clinical practices (such as vaccination or access to HIV antiretroviral treatment), school-based interventions (such as government-mandated nutritional content and physical activity), and other public policies.
Among the 70 unique quantitative implementation measures, 15 measures were deemed mostly transferable (at least 75% transferable, Table Table4). 4 ). Twenty-three measures were categorized as partially transferable (25 to 74% of items deemed transferable, Table Table5); 5 ); 32 measures were setting-specific (< 25% of items deemed transferable, data not shown).

QI quality improvement
Among the 70 measures, the most commonly assessed implementation outcomes were fidelity/compliance of the policy implementation to the government mandate (26%), acceptability of the policy to implementers (24%), perceived appropriateness of the policy (17%), and feasibility of implementation (17%) (Table (Table2). 2 ). Fidelity/compliance was sometimes assessed by asking implementers the extent to which they had modified a mandated practice [ 45 ]. Sometimes, detailed checklists were used to assess the extent of compliance with the many mandated policy components, such as school nutrition policies [ 83 ]. Acceptability was assessed by asking staff or healthcare providers in implementing agencies their level of agreement with the provided statements about the policy mandate, scored in Likert scales. Only eight (11%) of the included measures used multiple transferable items to assess adoption, and only eight (11%) assessed penetration.
Twenty-six measures of implementation costs were found during full-text screening (10 in included studies and 14 in excluded studies, data not shown). The cost time horizon varied from 12 months to 21 years, with most cost measures assessed at multiple time points. Ten of the 26 measures addressed direct implementation costs. Nine studies reported cost modeling findings. The implementation cost survey developed by Vogler et al. was extensive [ 53 ]. It asked implementing organizations to note policy impacts in medication pricing, margins, reimbursement rates, and insurance co-pays.
Within the 70 included measures, the most commonly assessed implementation determinants were readiness for implementation (61% assessed any readiness component) and the general organizational culture and climate (39%), followed by the specific policy implementation climate within the implementation organization/s (23%), actor relationships and networks (17%), political will for policy implementation (11%), and visibility of the policy role and policy actors (10%) (Table (Table2). 2 ). Each component of readiness for implementation was commonly assessed: communication of the policy (31%, 22 of 70 measures), policy awareness and knowledge (26%), resources for policy implementation (non-training resources 27%, training 20%), and leadership commitment to implement the policy (19%).
Only two studies assessed organizational structure as a determinant of health policy implementation. Lavinghouze and colleagues assessed the stability of the organization, defined as whether re-organization happens often or not, within a set of 9-point Likert items on multiple implementation determinants designed for use with state-level public health practitioners, and assessed whether public health departments were stand-alone agencies or embedded within agencies addressing additional services, such as social services [ 69 ]. Schneider and colleagues assessed coalition structure as an implementation determinant, including items on the number of organizations and individuals on the coalition roster, number that regularly attend coalition meetings, and so forth [ 72 ].
Tables Tables4 4 and and5 5 present the 38 measures of implementation outcomes and/or determinants identified out of the 70 included measures with at least 25% of items transferable (useable in other studies without wording changes or by changing only the policy name or other referent). Table Table4 4 shows 15 mostly transferable measures (at least 75% transferable). Table Table5 5 shows 23 partially transferable measures (25–74% of items deemed transferable). Separate measure development articles were found for 20 of the 38 measures; the remaining measures seemed to be developed for one-time, study-specific use by the empirical study authors cited in the tables. Studies listed in Tables Tables4 4 and and5 5 were conducted most commonly in the USA ( n = 19) or Europe ( n = 11). A few measures were used elsewhere: Africa ( n = 3), Australia ( n = 1), Canada ( n = 1), Middle East ( n = 1), Southeast Asia ( n = 1), or across multiple continents ( n = 1).
Figure Figure2 2 shows the median pragmatic quality ratings across the 38 measures with at least 25% transferable items shown in Tables Tables4 4 and and5. 5 . Higher scores are desirable and indicate the measures are easier to use (Table (Table3). 3 ). Overall, the measures were freely available in the public domain (median score = 4), brief with a median of 11–50 items (median score = 3), and had good readability, with a median reading level between 8th and 12th grade (median score = 3). However, instructions on how to score and interpret item scores were lacking, with a median score of 1, indicating the measures did not include suggestions for interpreting score ranges, clear cutoff scores, and instructions for handling missing data. In general, information on training requirements or availability of self-training manuals on how to use the measures was not reported in the included study or measure development article/s (median score = 0, not reported). Total pragmatic rating scores among the 38 measures with at least 25% of items transferable ranged from 7 to 17 (Tables (Tables4 4 and and5), 5 ), with a median total score of 12 out of a possible total score of 20. Median scores for each pragmatic characteristic were the same across all measures as for the 38 mostly or partially transferable measures, with a median total score of 11 across all measures.
Pragmatic rating scale results across identified measures. Footnote: pragmatic criteria scores from Psychometric and Pragmatic Evidence Rating Scale (PAPERS) (Lewis et al. [ 11 ], Stanick et al. [ 42 ]). Total possible score = 20, total median score across 38 measures = 11. Scores ranged from 0 to 18. Rating scales for each domain are provided in Supplemental Table 4
Few psychometric properties were reported. The study team found few reports of pilot testing and measure refinement as well. Among the 38 measures with at least 25% transferable items, the psychometric properties from the PAPERS rating scale total scores ranged from − 1 to 17 (Tables (Tables4 4 and and5), 5 ), with a median total score of 5 out of a possible total score of 36. Higher scores indicate more types of validity and reliability were reported with high quality. The 32 measures with calculable norms had a median norms PAPERS score of 3 (good), indicating appropriate sample size and distribution. The nine measures with reported internal consistency mostly showed Cronbach’s alphas in the adequate (0.70 to 0.79) to excellent (≥ 90) range, with a median of 0.78 (PAPERS score of 2, adequate) indicating adequate internal consistency. The five measures with reported structural validity had a median PAPERS score of 2, adequate (range 1 to 3, poor to good), indicating the sample size was sufficient and the factor analysis goodness of fit was reasonable. Among the 38 measures, no reports were found for responsiveness, convergent validity, discriminant validity, known-groups construct validity, or predictive or concurrent criterion validity.
In this systematic review, we sought to identify quantitative measures used to assess health policy implementation outcomes and determinants, rate the pragmatic and psychometric quality of identified measures, and point to future directions to address measurement gaps. In general, the identified measures are easy to use and freely available, but we found little data on validity and reliability. We found more quantitative measures of intra-organizational determinants of policy implementation than measures of the relationships and interactions between organizations that influence policy implementation. We found a limited number of measures that had been developed for or used to assess one of the eight IOF policy implementation outcomes that can be applied to other policies or settings, which may speak more to differences in terms used by policy researchers and D&I researchers than to differences in conceptualizations of policy implementation. Authors used a variety of terms and rarely provided definitions of the constructs the items assessed. Input from experts in policy implementation is needed to better understand and define policy implementation constructs for use across multiple fields involved in policy-related research.
We found several researchers had used well-tested measures of implementation determinants from D&I research or from organizational behavior and management literature (Tables (Tables4 4 and and5). 5 ). For internal setting of implementing organizations, whether mandated through public policy or not, well-developed and tested measures are available. However, a number of authors crafted their own items, with or without pilot testing, and used a variety of terms to describe what the items assessed. Further dissemination of the availability of well-tested measures to policy researchers is warranted [ 9 , 13 ].
What appears to be a larger gap involves the availability of well-developed and tested quantitative measures of the external context affecting policy implementation that can be used across multiple policy settings and topics [ 9 ]. Lack of attention to how a policy initiative fits with the external implementation context during policymaking and lack of policymaker commitment of adequate resources for implementation contribute to this gap [ 23 , 93 ]. Recent calls and initiatives to integrate health policies during policymaking and implementation planning will bring more attention to external contexts affecting not only policy development but implementation as well [ 93 – 99 ]. At the present time, it is not well-known which internal and external determinants are most essential to guide and achieve sustainable policy implementation [ 100 ]. Identification and dissemination of measures that assess factors that facilitate the spread of evidence-informed policy implementation (e.g., relative advantage, flexibility) will also help move policy implementation research forward [ 1 , 9 ].
Given the high potential population health impact of evidence-informed policies, much more attention to policy implementation is needed in D&I research. Few studies from non-D&I researchers reported policy implementation measure development procedures, pilot testing, scoring procedures and interpretation, training of data collectors, or data analysis procedures. Policy implementation research could benefit from the rigor of D&I quantitative research methods. And D&I researchers have much to learn about the contexts and practical aspects of policy implementation and can look to the rich depth of information in qualitative and mixed methods studies from other fields to inform quantitative measure development and testing [ 101 – 103 ].
This systematic review has several limitations. First, the four levels of the search string and multiple search terms in each level were applied only to the title, abstract, and subject headings, due to limitations of the search engines, so we likely missed pertinent studies. Second, a systematic approach with stakeholder input is needed to expand the definitions of IOF implementation outcomes for policy implementation. Third, although the authors value intra-organizational policymaking and implementation, the study team restricted the search to governmental policies due to limited time and staffing in the 12-month study. Fourth, by excluding tools with only policy-specific implementation measures, we excluded some well-developed and tested instruments in abstract and full-text screening. Since only 12 measures had 100% transferable items, researchers may need to pilot test wording modifications of other items. And finally, due to limited time and staffing, we only searched online for measures and measures development articles and may have missed separately developed pragmatic information, such as training and scoring materials not reported in a manuscript.
Despite the limitations, several recommendations for measure development follow from the findings and related literature [ 1 , 11 , 20 , 35 , 41 , 104 ], including the need to (1) conduct systematic, mixed-methods procedures (concept mapping, expert panels) to refine policy implementation outcomes, (2) expand and more fully specify external context domains for policy implementation research and evaluation, (3) identify and disseminate well-developed measures for specific policy topics and settings, (4) ensure that policy implementation improves equity rather than exacerbating disparities [ 105 ], and (5) develop evidence-informed policy implementation guidelines.
Easy-to-use, reliable, and valid quantitative measures of policy implementation can further our understanding of policy implementation processes, determinants, and outcomes. Due to the wide array of health policy topics and implementation settings, sound quantitative measures that can be applied across topics and settings will help speed learnings from individual studies and aid in the transfer from research to practice. Quantitative measures can inform the implementation of evidence-informed policies to further the spread and effective implementation of policies to ultimately reap greater population health benefit. This systematic review of measures is intended to stimulate measure development and high-quality assessment of health policy implementation outcomes and predictors to help practitioners and researchers spread evidence-informed policies to improve population health and reduce inequities.

Metrics details
The Common Risk Factor Approach (CRFA) is one of the methods to achieve medical-dental integration. CRFA addresses shared risk factors among major Non-communicable Diseases (NCDs). This study aimed to explore the perspectives of dental and medical practitioners concerning CRFA for managing NCDs and periodontal diseases and to create and validate a tool to evaluate the Knowledge, Attitude, and Practice (KAP) of medical and dental practitioners in relation to utilization of CRFA for management of NCDs and Periodontal diseases.
This research employed a concurrent mixed-method model and was carried out from January 2021 to February 2022, focusing on medical and dental practitioners in South India. In the qualitative phase, online interviews were conducted with dental and medical practitioners, recorded, and transcribed. Thematic analysis was applied after achieving data saturation. In the quantitative phase, a KAP questionnaire was developed. The sample size was determined by using the G power statistical power analysis program. A sample size of 220 in each group (dentists and medical practitioners) was estimated. Systematic random sampling was used to recruit the potential participants. The data obtained through the online dissemination of KAP tool was analysed and scores were standardized to categorize the KAP.
Qualitative thematic analysis identified four major themes: understanding of common risk factors, risk factor reduction and disease burden, integrating CRFA into clinical practice, and barriers to CRFA. In addition, thematic analysis revealed seventeen subthemes. For the quantitative phase, standardization was applied to a 14-item KAP questionnaire for medical practitioners and a 19-item KAP questionnaire for dental practitioners. The total KAP score for medical practitioners in the study was 21.84 ± 2.87, while dental practitioners scored 22.82 ± 3.21, which indicated a high level of KAP regarding CRFA. Meta integration of qualitative and quantitative data identified eight overarching themes: four were concordant, three were discordant, and one theme provided the explanatory component.
The study’s structured, validated questionnaire showed that both medical and dental professionals had a high knowledge of CRFA. However, they were not appreciably aware of the risk factors that are shared between NCDs and periodontal disease. Both groups were interested in the idea of using CRFA in integrated medical and dental care.
Peer Review reports
Non-communicable diseases (NCDs) account for more than 41 million deaths globally each year [ 1 ]. These diseases are influenced by both non-modifiable and modifiable risk factors [ 2 ]. Periodontal disease, another multifactorial non-communicable ailment, shares several risk factors with NCDs. Individuals with periodontal diseases, particularly periodontitis, face a heightened risk of losing multiple teeth, leading to compromised masticatory function and altered dietary habits [ 3 ]. This not only affects the quality of life and self-esteem of affected individuals but also imposes significant socio-economic burdens and healthcare costs [ 4 ]. Despite the evident connections between periodontal disease and NCDs [ 5 , 6 ], there persists a historical divide between oral and general healthcare [ 7 ], further reinforced by the establishment of medical insurance [ 8 ]. This separation has contributed to out-of-pocket expenditures (OOPE) on dental care, accounting for approximately 14% of OOPE in Organisation for Economic Co-operation and Development (OECD) countries. [ 9 ] A recent study in South India revealed that 15.4% of sanitary workers experienced Catastrophic Dental Health Expenditure (CDHE) [ 10 ]. Additionally, a global study involving 41 low- and middle-income countries found that 7% of households faced CDHE [ 11 ].
The integration of dental and medical care would bring substantial benefits to the general population. Oral health has a significant impact on general health. Simple, non-invasive periodontal therapy was found to result in a remarkable (40–70%) reduction in medical costs and hospitalizations for individuals with conditions such as diabetes, coronary artery disease, or during pregnancy [ 12 ]. This underscores the potential advantages of addressing oral health within the broader spectrum of healthcare, leading to improved overall health outcomes and reduced healthcare costs.
Several methods of integrating medical and dental care have been explored, [ 13 , 14 , 15 ] and one such strategy is risk reduction for disease prevention. Common risk factors such as smoking, obesity, poor nutrition, low socioeconomic status, stress, and inadequate oral hygiene are shared by both periodontitis and NCDs [ 5 ]. Traditional health promotion tends to focus on specific diseases, potentially contributing to the separation of oral health from general health. An alternative approach, the Common Risk Factor Approach (CRFA), addresses shared risk factors among major NCDs, including oral diseases. CRFA emphasizes managing contributing elements to enhance overall population health.
The approaches within CRFA aim to mitigate the impact of common chronic diseases [ 13 ] and include integrated action against shared risk factors and altering one risk factor that may influence others, leading to a cascade effect. For instance, changing smoking behavior could impact related behaviors like alcohol consumption and diet. Collaborative efforts across sectors, concentrating upstream on basic etiological factors, can lead to progress in oral health improvement and decreased oral health inequalities [ 16 ]. Given the clustering of both modifiable and non-modifiable risk factors in patients with NCDs and periodontal diseases, CRFA emerges as a cost-effective and rational approach [ 13 ]. Of these risk factors, modifiable risk factors can be controlled or changed. The control or modification of a few key risk factors can have a substantial impact on managing numerous chronic conditions.
The World Health Organization (WHO) advocates a global strategy for enhancing oral health alongside overall health, emphasizing shared risk factors [ 17 ]. Implementing CRFA for overall health, including oral health, presents opportunities to integrate oral health promotion into broader health policies, such as those related to food [ 15 ]. However, successful implementation requires appropriate evidence, guidelines, and policies due to perceived challenges in applying CRFA for oral health promotion [ 15 ].
To comprehensively assess the potential initiation of the CRFA for NCDs, including periodontal disease, it is crucial to understand the knowledge, attitudes, and practices of medical and dental practitioners regarding shared risk factors. While previous studies have explored knowledge about periodontitis risk factors among medical practitioners and the general population, [ 18 , 19 ] there is a notable gap in understanding the KAP of both medical and dental practitioners regarding shared risk factors between NCDs and periodontitis and the integration of CRFA into medical and dental practices.
Capacity-building measures are essential for implementing CRFA-based programs [ 15 ], and assessing the baseline KAP of the target population will bridge the evidence gap for integrations. Despite the pivotal role of CRFA in addressing health issues, there is currently no standardized instrument tailored to assess practitioners’ KAP in this context. Questionnaires are commonly used for KAP assessment [ 20 ], and a structured, validated questionnaire is essential for obtaining clear information on practitioners’ understanding and application of CRFA in managing NCDs and periodontal diseases.
The objectives of this mixed-method study are to address these gaps by understanding practitioners’ opinions on CRFA and developing a validated structured instrument to assess the Knowledge, Attitude, and Practice of medical and dental practitioners toward the use of CRFA for managing NCDs and periodontal diseases. The study will employ both quantitative and qualitative methods, utilizing a structured questionnaire to capture practitioners’ perspectives and incorporating open-ended communication to gain insights into the reasons behind their opinions, support, and potential hurdles in implementing CRFA in the Indian context.
The mixed-method study received ethical approval from the institutional ethics committee and institutional review board, and informed consent was obtained from the participants during the conduct of the study.
The study employed a concurrent mixed-methods model, incorporating both qualitative and quantitative arms, to holistically investigate the research questions. This approach combines the advantages of qualitative and quantitative data, allowing for a comprehensive exploration of the CRFA. The qualitative arm provides in-depth insights into the complex phenomena associated with CRFA, offering a contextual richness that complements the quantitative results. The lists of potential participants were obtained from the list of dentists and medical practitioners of Kerala, Karnataka, Tamil Nadu, Andhra Pradesh, Telangana, and Goa available through the regional Indian Dental Association (IDA), Indian Medical Association (IMA), and directories of medical and dental practitioners. Based on the data obtained from the directories, a state-wise distribution of samples was done. Systematic random sampling was used to select the possible participants for the study from January 2021 to February 2022.
Study context and population.
The qualitative segment of the study sought to delve into the viewpoints of experts in medicine and general dental practice, particularly those possessing relevant expertise related to the CRFA. Participants were selected from specialties such as endocrinology, gynaecology, otorhinolaryngology, periodontology, general medicine, and general dentistry, based on their relevance to the shared risk factors between periodontal disease and various medical conditions. Purposive sampling was employed to recruit a diverse group of medical and dental practitioners, and the sampling units were identified from the directories of professional associations like the Indian Dental Association (IDA) and the Indian Medical Association (IMA). Participation in the online interviews using the ‘Zoom Meetings’ online platform was voluntary. After obtaining their consent, the link for the Zoom meeting was shared with the participants. Participants received acknowledgment certificates as an incentive. No explicit exclusion criteria were set, ensuring a broad representation of perspectives across the selected fields.
The qualitative phase of the study utilized in-depth interview guides that covered similar topics for both dental and medical practitioners. These guides included components related to the understanding of common risk factors, risk factor reduction, and disease burden, suggested methods for integrating CRFA into clinical practice, and barriers to CRFA. The semi-structured questions were developed a priori, drawing from existing literature. The interviews were conducted with consent, and a note-keeper recorded the proceedings, while in-depth interviews were recorded for transcription. The recordings were transformed into verbatim transcripts at the end of each day.
The number of participants for in-depth interviews was determined based on achieving data saturation, ensuring that the sample size was sufficient to capture a diverse range of perspectives until no new information or themes emerged. Data saturation enhances the credibility and trustworthiness of study findings, signifying theoretical sufficiency. The analysis methodology involved progressive analysis throughout the study, allowing for the incremental identification and incorporation of themes and sub-themes after each interview. This iterative process facilitated the continual refinement of emerging data patterns.
The decision to conclude interviews was guided by the observation of the ceased emergence of new themes, indicating data saturation. Close monitoring of interview data helped identify a point where further sessions yielded no novel insights or themes. After achieving data saturation, a comprehensive final thematic analysis was conducted following guidelines by Braun and Clark [ 21 ] and reiterated by Kiger et al [ 22 ]. This analysis involved data review, coding, categorization, and synthesis to derive conclusive themes and sub-themes. Each transcript underwent review by two researchers, and emerging themes were developed, involving a third author in cases of disagreement. Consensus on codes, categories, and themes was reached through regular discussions. The data was organized and managed using computer-assisted qualitative research software, QDA Miner Lite (Version 2.0.7; Provalis Research).
The quantitative segment of the mixed-method study focused on developing and validating a KAP questionnaire on the CRFA for the integration of medical and dental care. Distinct questionnaires were created for medical and dental practitioners. The development of the questionnaire occurred in two stages.
In the first stage, item and domain development took place, involving a deductive approach to form initial questions, followed by content validation and test-retest reliability. The second stage involved the validation of the questionnaire through item response theory, exploratory factor analysis, and internal consistency reliability assessment. This two-stage process ensured the robustness and appropriateness of the questionnaire for assessing the KAP of medical and dental practitioners regarding CRFA in the context of managing NCDs and Periodontal diseases.
The study included both medical practitioners and dental practitioners, encompassing those with and without a postgraduate degree or specialization. This diverse inclusion aimed to capture perspectives from practitioners with varying levels of education and expertise, providing a comprehensive understanding of the knowledge, attitudes, and practices related to the CRFA among professionals in both fields.
The sample size was determined by using the G power statistical power analysis program. Based on the findings from a previous study [ 23 ] a sample size of 220 dentists and medical practitioners was estimated. This was done by taking into account the Chi-square test’s effect size of 0.30, the study’s power of 0.95, and the number of groups of medical and dental practitioners that could be used to compare mean knowledge, attitude, and practice scores.
The study utilized a systematic approach for sampling dental and medical practitioners from Kerala, Karnataka, Tamil Nadu, Andhra Pradesh, Telangana, and Goa. The directories of the regional Indian Dental Association (IDA) and Indian Medical Association (IMA) were consulted to compile a list of practitioners (both specialists and general practitioners). To ensure a representative sample, the distribution of participants was organized by state (Table 1 ).
Systematic random sampling was employed to select potential participants, minimizing bias in participant selection. Contact details were then used to send a web-based questionnaire via Google Forms, accompanied by an invitation to participate. Anticipating a 50% non-response rate, the questionnaires were distributed to twice the required number of participants. The final analysis included responses from 225 medical practitioners and 307 dental practitioners across South India.
The development and validation of the KAP questionnaire occurred in two distinct stages. In the first stage, item and domain development were undertaken through a three-step process: (i) Deductive approach, (ii) Content validation, (iii) Test-retest reliability. The second stage involved the validation of the questionnaire using: (i) Item response theory, (ii) Exploratory factor analysis, (iii) Internal consistency reliability assessment. Subsequently, scores were standardized to categorize the KAP of the population into low, medium, and high categories. This multi-stage process ensured the reliability and validity of the questionnaire for assessing participants’ knowledge, attitude, and practice regarding the CRFA.
Stage one: item and domain development
The deductive approach was employed to develop items for the questionnaire based on existing literature related to the CRFA in the management of periodontal disease and NCDs. Eight referenced articles contributed to the conceptual definition of knowledge, attitude, and practice regarding CRFA [ 23 , 24 , 25 , 26 , 27 , 28 , 29 , 30 ]. The definition of CRFA emphasized its role in creating cross-disciplinary health promotion programs that address common risk factors for diseases. Knowledge, attitude, and practice were defined in terms of awareness, thoughts, behaviors, and understanding of shared risk factors and etiology related to periodontal disease and NCDs, as well as CRFA.
The initial questionnaire, developed in English, consisted of 28 items for the dental questionnaire and 24 items for the medical questionnaire, distributed across four domains: (1) Demography of participants; (2) Knowledge towards CRFA for NCDs and oral health; (3) Attitude towards CRFA for NCDs and oral health; and (4) Practice towards implementing CRFA for NCDs and oral health. To ensure content validity, the initial questionnaire underwent review by an expert panel comprising dental and medical practitioners. The test-retest reliability of the questionnaire was assessed by administering it twice to 30 participants within a one-month timeframe.
The study included responses from 225 medical practitioners and 307 dental practitioners across six states in South India to evaluate the additional psychometric properties of the questionnaire. Data analysis was conducted using JMETRIK software.
In the knowledge domain, a two-parameter logistic item response theory (2-PL IRT) analysis was conducted using responses categorized as either correct or incorrect. The analysis was performed in JMETRIK (version 4.0.0, Charlottesville, Virginia, USA) using the RASCH (log odds ratio) limited package. The analysis considered the range of difficulty (-4 to + 4) and discrimination (0.20 to infinity) as the cut-off values for evaluating psychometric properties. Item fit was assessed using chi-square goodness-of-fit per item, and p values were reported. The modified parallel analysis was employed to evaluate one-dimensionality.
The adequacy of sampling was assessed using the Kaiser–Meyer–Olkin measure (KMO) and Bartlett’s test of sphericity [ 20 ]. A KMO value above 0.5 and a significant result in Bartlett’s test ( p < 0.001) were considered indicative of a sufficient sample.
The internal consistency (IC) of the items was calculated using the coefficient of Cronbach’s alpha [ 31 ] and correlation between items.
The responses to the questions in the Knowledge, Attitude, and Practice groups were coded, and scores were calculated for each group. The scores were then split into percentiles for standardization. The total KAP score was also calculated and interpreted as low KAP (0 to 24th percentile), medium KAP (25th to 75th percentile), and high KAP (76th to 100th percentile) based on the percentile scores [ 32 ].
In-depth interviews involved five medical practitioners specializing in endocrinology, gynaecology, otorhinolaryngology, and general medicine, along with five general dental practitioners and five periodontists. The qualitative thematic analysis identified four major themes: understanding of common risk factors, risk factor reduction and disease burden, integrating CRFA into clinical practice, and barriers to CRFA. Subsequently, seventeen subthemes emerged, encompassing topics such as enumerating risk factors, transitioning from disease-specific to risk factor approaches, diagnosing systemic NCDs through identifying risk factors and oral signs, controlling risk factors and NCD burden, the impact of periodontal therapy on NCD burden, the influence of medical practitioners over periodontists, measures for integrating CRFA, barriers to integration, and more.
The study revealed that medical and dental practitioners, including periodontists, demonstrated awareness of the association between diabetes and periodontal disease, as well as the shared risk factor of smoking. However, their knowledge regarding risk factors common to other major NCDs and periodontal disease was limited. Many practitioners were unable to identify shared risk factors such as obesity, the presence of oral pathogens, and nutritional deficiency [ 5 ]. This knowledge gap may be attributed to the prevailing practice of treating patients based on specific diseases rather than targeting shared risk factors. Although there is a gradual shift toward a risk factor-based approach in certain specialties, there remains a general scepticism about patient compliance with long-term risk factor reduction strategies. The subthemes that emerged under this major theme are: (i) Enumeration of the risk factors (ii) Transition from disease specific to risk factor approach (iii) Diagnosis of a systemic NCD through identification of presence of risk factors and oral signs .
‘There are many risk factors, ranging from smoking to genetics. Very common ones are smoking, alcohol, lifestyle. Each and every factor has a specific role. Genetics has a significant role. If a parent is diabetic by his or her 50s then the next generation will become diabetic by 30s’. (MP1)
There was a consensus regarding the need for a change from a disease specific approach to a risk factor approach.
MP1 had supported CRFA. ‘This is a very good approach. Common risk factors are present for many diseases. So, if we can create an awareness regarding smoking, alcohol, and sedentary lifestyle, it can significantly reduce the development of many diseases.’
The identification of clustering of risk factors for periodontal disease and NCDs in patients, in addition to the occurrence of oral signs, can sometimes lead to the diagnosis of systemic diseases.
PR5 ‘In diabetes we have noticed. They come with multiple abscesses, then we advise them to check the blood glucose level and they are diagnosed with diabetes. They are not aware of the condition before. So, once we treat the patient and with the consultation with the diabetologist, we have noticed an improvement in the status.’
All practitioners concurred on the potential positive impact of early identification of risk factors, counselling, and reducing risk factors to mitigate disease burden. Nevertheless, medical practitioners acknowledged that a significant portion of them tend to overlook oral health, possibly due to a lack of awareness regarding its association with systemic conditions. The thematic analysis revealed subthemes such as (i) Control of Risk Factors and Impact on NCD Burden (ii) The Role of Periodontal Therapy in Alleviating the NCD Burden (iii) Reciprocal Impact of Other NCD Therapies on Periodontal Disease Burden (iv) Influence of Medical Practitioners in Shaping Patient Decisions Over Periodontists. These subthemes underscored the interconnectedness of risk factors, diverse therapies, and the collaborative role of medical and dental practitioners in addressing both oral and systemic health.
PR1 stated that ‘Lifestyle modification…I have been following the periodontal patients in my clinic. There are patients whom I have been following for last 6 to 7 years. Patients who have been motivated to maintain the oral hygiene, their rate of progression (of periodontal disease) and diabetic control is much better than patients who are not maintaining their oral hygiene properly.’
The dental practitioners have observed that periodontal therapy can result in improving the NCD status and that a better compliance is observed when the advice is given by a medical practitioner.
‘Yes, after periodontal treatment, sugar level often reduces as noticed in diabetes. Diabetics with uncontrolled sugar levels, fluctuating sugar levels, after periodontal therapy usually have better controlled sugar levels’, GP1 said.
PR3 said, ‘Yes definitely, when a physician refers the patient to us, they are more willing to listen to us and adapt to whatever changes we say.’
Various approaches have been proposed to integrate the CRFA into clinical practice. These strategies encompass capacity building initiatives to promote medical-dental integration, such as establishing NCD clinics; raising awareness among the medical community regarding the interconnectedness of medical and dental health; advocating for policies that underscore the significance of CRFA integration in clinical settings; developing effective healthcare referral systems and cross-disciplinary health promotion strategies, including oral health care; and encouraging patient education and motivation. The subthemes within this overarching theme are: (i) Capacity Building (ii) Advocacy and Policy Implications (iii) Healthcare Partnerships Involving Referrals and Cross-Disciplinary Health Promotion Strategies (iv) Patient Education and Motivation.
The interviews highlighted diverse strategies for capacity building, including the implementation of regular check-ups and screening camps as integral components of healthcare services. Furthermore, suggestions encompassed the use of awareness posters and videos, adoption of evidence-based practices, and the establishment of NCD clinicsx [ 33 ]. NCD clinics, as proposed, would serve as essential hubs for screening, diagnosing, and managing NCDs. These clinics would offer comprehensive examinations, including diet counselling, lifestyle management, and home-based care. Patients could be referred to these clinics by other healthcare centres, health workers, or they could directly report to the clinic, enabling the identification and management of complications or advanced stages of NCDs. MP1 stated, ‘In government clinics, there are NCD clinic. Along with the NCD clinic, if a dental clinic can be set up, a lot of cases with oral manifestations will be diagnosed. So integrated clinics with NCD and dental will be very useful.’
Advocacy enables stakeholders and government decision-makers to have discussions and bring out suggestions and recommendations to a prevailing policy that is of interest to them.
MP1 Suggested that ‘Even for a job opportunity, basic examination is physical examination and evaluation for systemic diseases. Oral examination may be included in the basic fitness requirement for the job.’
Interdisciplinary collaboration is also essential for medical dental integration as stated by MP3, ‘There should be a rapport between the medical and dental practitioner so that there is communication regarding the cases and there is a follow-up of the cases.’
Communication through mass media and other visual aids, generating social and cultural awareness for patient education, and motivation for holistic health care have also been suggested to facilitate the implementation of integrated care delivery.
PR2 has mentioned, ‘When this gets published, apart from journals, this should reach the common population also. The common population rarely see the journal articles. So, it should be brought forth in mass media so that it reaches the population.’
CRFA is considered a relatively novel approach, as the comprehensive exploration of shared risk factors and risk reduction strategies for common NCDs and periodontal disease is a recent development. The lack of awareness regarding this concept has been identified as a significant barrier to its implementation, coupled with challenges such as time constraints, concerns about the sustainability of long-term risk reduction strategies, and the need for extended resources. Moreover, the existing strict specialization within healthcare disciplines and the lack of interdisciplinary coordination pose additional obstacles to the effective execution of CRFA. The subthemes encompass: (i) Lack of awareness (ii) Time constraints (iii) Sustainability (iv) Long-term outcomes or no outcomes (v) Lack of resources (vi) Lack of interdisciplinary coordination and strict specialization.MP2 said ‘One is that among us practitioners, we do not give due significance to the link between oral health and systemic health. There are no awareness programs as far as I know. The emphasis is less’.
GP5 said, ‘They (medical practitioners) don’t have time to peep into the oral cavity to say you have caries, go to a dentist or say you have diabetes and there is a chance to develop periodontal disease. Such opportunities are less.’
The results of following the risk reduction strategies may take a long time to manifest, and sometimes the outcomes are not as significant as what the patient would have expected. This results in a spiralling of the patient’s attitude and a failure of further follow-up.
‘In long term, the patients may become uncooperative, and patients will not be willing for a follow-up, they will go for things that have cost-benefit’MP1.
The lack of resources, manpower and facilities to deliver the care act as significant barriers to implementation of CRFA.
MP3 has stated, ‘Cost is a problem, social acceptance is a problem, policy makers and political involvement are a problem, lack of communication between communities…In the western countries, like UK, they have NHS care, we don’t have that in India and patients hence don’t go for any care if they feel it is unnecessary’.
i) Content validation
The total number of questions included in the dental and medical questionnaires using the deductive approach was 28 and 24 respectively. After discussion, one question was eliminated from both the medical and dental questionnaires as it had a similar connotation to a previous question. Content validation of each scale was performed by five experts to ensure content relevance, representativeness, and technical quality. The KAP questionnaire was reduced to 26 questions for dental practitioners after content validation. Item reduction was performed to 22 for the questionnaire for medical practitioners after eliminating 1 question. A few questions were rephrased based on the suggestions given by the expert panel prior to administering the questionnaire for test-retest reliability assessment. The details of content validation are given in Table 2 .
ii) Test-re test reliability
The scoring of items was done, and the data was utilized to assess the reliability of the questionnaire. 21 questions in dental and medical questionnaires were subjected to test-retest reliability assessment. Five questions in the dental questionnaire were option questions, leading questions, or open-ended questions (Eg: Are you a periodontist) and one question in the medical questionnaire was open ended, hence they were not subjected to test-retest reliability. The unweighted Kappa coefficient was used to assess the reliability of the items with binary responses (Table 3 ). The intraclass correlation coefficient (ICC) was used for assessing the questions in the attitude category with categorical variables (Table 3 ). Based on the test-retest reliability assessment, three questions from the dental questionnaire and two questions from the medical questionnaire were eliminated.
iii)Psychometric evaluation of questionnaire
The 20-item medical and 23-item dental KAP questionnaires (including the open-ended and leading questions) were administered to 450 medical and dental practitioners, and responses were obtained from 225 samples in the medical stream and 307 in the dental stream.
In the medical KAP questionnaire, four items from the knowledge domain and one item each from the attitude and practice domain were eliminated owing to the high difficulty statistic. One item each from the knowledge and practice domain was retained considering the importance of the items, even though they had a higher difficulty range. After item reduction using item response theory, 14 items (including the open-ended question) remained in the final questionnaire for medical practitioners. The KMO sampling adequacy and test of sphericity for the domains of knowledge, attitude, and practice were found to be in an acceptable range. Internal consistency measured using Cronbach’s alpha improved from 0.471 to 0.658 for the attitude domain after item deletion. For knowledge and practice, the Cronbach’s alpha after item deletion was reported to be 0.553 and 0.727, respectively.
The 23-item questionnaire was reduced to 19 items with the elimination of 3 items from THE knowledge domain and single item from attitude domain. Two items with poor scores of difficulty were deemed to be important in the questionnaire and were not eliminated. After item reduction, a total of 14 items remained in the final questionnaire in addition to the five leading/option questions. The KMO sampling adequacy and test of sphericity for the domains of knowledge, attitude, and practice were found to be in acceptable range. Internal consistency measured using Cronbach’s alpha was found to be slightly reliable in case of the attitude domain (0.459). While for knowledge and practice domain internal consistency was within the acceptable range (Knowledge 0.634, Practice 0.513) after item deletion.
Multivariate logistic regression was attempted between the parameters such as age, gender, qualification, experience, type of service, location, and number of patients seen per day and the knowledge, attitude, and practice regarding CRFA for both medical and dental practitioners, and no significant results were obtained for both medical and dental practitioners. (The details of the psychometric evaluation of the questionnaire and the characteristics of the study population are given in supplementary file 1)
iv) standardization of scores
For the south Indian population, the 14 item questionnaire scores were standardized (Table 4 ).
The validated questionnaires for medical and dental practitioners are given in supplementary file 2. For the medical KAP questionnaire, scores below 14 indicated low KAP, scores between 15 and 18 indicated medium, and scores greater than 18 indicated good knowledge, attitude, and practice of CRFA. For dental practitioners, scores less than 16 were reported to be low KAP; scores 16 to 19 indicated medium level; and scores greater than 20 indicated a good level of knowledge, attitude, and practice regarding CRFA.
Total KAP amongst the medical practitioners who participated in the present study was 21.84 ± 2.87 and that of dental practitioners was 22.82 ± 3.21. Both values indicated a high level of KAP amongst the participants regarding CRFA.
Eight overarching themes emerged in the meta integration of the qualitative and quantitative data (Fig. 1 ). The themes that had a confirmatory fit as assessed from both the quantitative and qualitative aspects of the study include (i) awareness of common risk factors for NCDs including periodontal diseases, (ii) neglect of dental status while assessing general health, (iii) awareness of effect of systemic diseases on oral health, (iv) awareness of risk factor reduction and improvement of NCD status. Contradictory observations from the quantitative and qualitative arms of the study resulted in a discordant fit in the following themes: (i) regular follow-up of periodontal health of patients with NCDs (ii) awareness regarding need for referral for periodontal examination and management in patients with NCDs (iii) awareness of perio-systemic interlink. The qualitative arm of the study explained the theme ‘Reasons for lack of referral to dental practitioners by medical practitioners’ and provided reasons such a reduced emphasis on oral health with a lack of awareness regarding the same amongst the practitioners, resource and time constraints that prevent the medical practitioners from looking into the overall health of the patient apart from the presenting complaint, overspecialization of the medical field with focus only on the specific field of specialization, to state a few.
Awareness of common risk factors for NCDs including periodontal diseases
NCDs and periodontal disease pose substantial societal burdens in terms of economic costs and years lost to ill-health, disability, or premature death [ 34 ]. Various factors, including social, demographic, environmental, behavioural, and personal elements, predispose individuals to major NCDs and oral diseases [ 5 ]. The CRFA addresses these shared risk factors, allowing the regulation of a few risk factors to exert a significant impact on controlling multiple chronic conditions [ 5 ]. This study has successfully developed and validated a questionnaire with satisfactory content validity and reliability to assess the knowledge, attitude, and behavior regarding CRFA for managing NCDs and periodontal disease.
To the best of our knowledge, this is the first study to create a suitable questionnaire for this purpose, incorporating a qualitative component to comprehend potential pathways and barriers to CRFA implementation. All retained questionnaire items demonstrated discrimination and difficulty parameters within acceptable ranges [ 20 ]. The KAP questionnaire exhibited acceptable internal consistency, validating its effectiveness for assessing CRFA-related KAP.
A crucial finding is the lack of understanding among medical and dental practitioners regarding common risk factors for NCDs and periodontal disease, hindering the implementation of CRFA. Literature that demonstrates the presence of shared risk factors between periodontal disease and other non-communicable diseases has, perchance, not been extensively explored by the health-care community. Almeida et al., in their systematic review, showed that the inflammatory mediators CRP and IL-6 had a significant association with both periodontitis and atherosclerosis [ 35 ]. A study by Arregoces et al. [ 36 ] showed an increase in ultrasensitive CRP (usCRP) in acute myocardial infarction (AMI), diabetes and periodontal disease. abdominal obesity [ 37 ] and insulin resistance [ 38 ] are proven to be contributing risk factors for metabolic syndrome and periodontal disease. The risk for CVD and periodontal disease is related to poor glycemic control, dyslipidemia, and chronic inflammatory state [ 39 , 40 , 41 ]. Smoking has been proven as a risk factor for periodontal disease, hypertension, diabetes, and metabolic syndrome through several studies [ 42 , 43 , 44 , 45 ]. Holmlund et al. have demonstrated the association between immunoglobulin G levels against P gingivalis and the risk for AMI and periodontal disease [ 46 ]. The presence of Aggregatibacter actinomycetemcomitans (Aa) is shown to be a risk factor for Coronary Artery Disease (CAD) and periodontal diseasecx [ 47 ]. The role of stress and depression as risk factors for CVD and periodontal disease has been investigated and recognized [ 48 ].
Apart from the lack of sufficient knowledge regarding the shared risk factors between periodontal disease and NCDs, there are additional barriers to the implementation of CRFA for the management of periodontal disease and NCDs. Barriers include time and resource constraints, oral health neglect in general health assessments, insufficient recognition of the need for oral health care referral for NCD patients, and limited acknowledgment of the perio-systemic interlink. However, the integration of medical and dental care is not impossible, and efforts such as creating awareness, education programs, mass media campaigns, and efficient referral systems are advocated by healthcare professionals.
The Health Resources and Services Administration (HRSA) has explained initiatives for incorporating oral health into primary medical care practice and training primary health care professionals in oral health assessment and clinical competencies [ 49 ]. The combination of preventive dental care with general health care practice can help reduce duplication of care modalities and expenses incurred. Six levels of integration, with the evolution of the key elements involved in the integration, from communication to physical proximity to practice change, have been described [ 50 ]. Communication is the key element in the first and second levels of integration in which there is minimal collaboration and basic collaboration at a distance respectively. Basic collaboration onsite and close collaboration onsite with some system integration form the third and fourth levels of integration, in which physical proximity is the key element. The fifth and sixth levels of integration include practice change, in which there is close collaboration with an integrated practice and full collaboration with a merged, integrated practice [ 50 ].
This research indicates that while the presence of shared risk factors among NCDs is acknowledged, medical practitioners often overlook the link between oral health and systemic health. Addressing this gap in healthcare practice involves providing basic oral health care training as an integral part of general health education.
In India, the checklist for early detection of NCDs, which is used in community based NCD surveillance, takes into consideration risk factors such as age of patient, smoking, alcohol consumption, measurement of waist, physical activities, and family history of NCDs [ 51 ]. These risk factors are similar to the risk factors for periodontal disease [ 13 ]. Thus, the risk factor surveillance may be extended to include periodontal disease as well. The primary healthcare teams can be trained in strategies to reduce or modify the risk factors associated with systemic diseases and oral diseases. The methods to assess the efficiency of the integrated practice in the primary health care setting include the calculation of the percentage of patients assessed using the surveillance tool, to the percentage of staff satisfied with the referral process [ 52 ]. Research conducted in Saudi Arabia showed that the availability of an appropriate source of oral health knowledge was significantly associated with increased odds of inter-disciplinary practice [ 53 ]. Regular patient reviews and examinations, along with the reinforcement of risk reduction strategies, can be achieved through the application of knowledge regarding shared risk factors, facilitating the efficient integration of medical and dental care.
This combined mixed-methods study has the limitation that the quantitative aspect was primarily conducted through online Google Forms, which were sent only to the medical and dental practitioners who are registered in the databases that were utilized in the study, and hence the representativeness of the sample may be compromised. However, given the study’s design, which provides insights into the perspectives of healthcare professionals in various fields, the results offer a valuable reflection of the KAP regarding CRFA among medical and dental practitioners.
The questionnaire derived from the quantitative segment of this study stands as a straightforward and effective tool for evaluating KAP related to the CRFA concerning both oral and general health. In alignment with the ongoing global efforts to enhance oral health strategies, CRFA emerges as a promising approach for seamlessly integrating medical and dental care. The qualitative aspect of this study showed that to foster this integration, key recommendations include raising awareness about the interconnectedness of oral and systemic conditions, addressing constraints related to time and resources, and establishing robust referral systems between medical and dental practitioners. These measures collectively aim to establish a unified and integrated medical-dental care system.

Metrics details
Healthcare waste is any waste generated by healthcare facilities that is considered potentially hazardous to health. Solid healthcare waste is categorized into infectious and non-infectious wastes. Infectious waste is material suspected of containing pathogens and potentially causing disease. Non-infectious waste includes wastes that have not been in contact with infectious agents, hazardous chemicals, or radioactive substances, similar to household waste, i.e. plastic, papers and leftover foods.
This study aimed to investigate solid healthcare waste management practices and develop guidelines to improve solid healthcare waste management practices in Ethiopia. The setting was all health facilities found in Hossaena town.
A mixed-method study design was used. For the qualitative phase of this study, eight FGDs were conducted from 4 government health facilities, one FGD from each private health facility (which is 37 in number), and forty-five FGDs were conducted. Four FGDs were executed with cleaners; another four were only health care providers because using homogeneous groups promotes discussion. The remaining 37 FGDs in private health facilities were mixed from health professionals and cleaners because of the number of workers in the private facilities. For the quantitative phase, all health facilities and health facility workers who have direct contact with healthcare waste management practice participated in this study. Both qualitative and quantitative study participants were taken from the health facilities found in Hossaena town.
Seventeen (3.1%) health facility workers have hand washing facilities. Three hundred ninety-two (72.6%) of the participants agree on the availability of one or more personal protective equipment (PPE) in the facility ‘‘ the reason for the absence of some of the PPEs, like boots and goggles, and the shortage of disposable gloves owes to cost inflation from time to time and sometimes absent from the market’’ . The observational finding shows that colour-coded waste bins are available in 23 (9.6%) rooms. 90% of the sharp containers were reusable, and 100% of the waste storage bins were plastic buckets that were easily cleanable. In 40 (97.56%) health facilities, infectious wastes were collected daily from the waste generation areas to the final disposal points. Two hundred seventy-one (50.2%) of the respondents were satisfied or agreed that satisfactory procedures are available in case of an accident. Only 220 (40.8%) respondents were vaccinated for the Hepatitis B virus.
Hand washing facilities, personal protective equipment and preventive vaccinations are not readily available for health workers. Solid waste segregation practices are poor and showed that solid waste management practices (SWMP) are below the acceptable level.
Peer Review reports
Healthcare waste (HCW) encompasses all types of waste generated while providing health-related services, spanning activities such as diagnosis, immunization, treatment, and research. It constitutes a diverse array of materials, each presenting potential hazards to health and the environment. Within the realm of HCW, one finds secretions and excretions from humans, cultures, and waste containing a stock of infectious agents. Discarded plastic materials contaminated with blood or other bodily fluids, pathological wastes, and discarded medical equipment are classified as healthcare waste. Sharps, including needles, scalpels, and other waste materials generated during any healthcare service provision, are also considered potentially hazardous to health [ 1 ].
Healthcare waste in solid form (HCW) is commonly divided into two primary groups: infectious and non-infectious. The existence of pathogens in concentrations identifies infectious waste or amounts significant enough to induce diseases in vulnerable hosts [ 1 ] If healthcare facility waste is free from any combination with infectious agents, nearly 85% is categorized as non-hazardous waste, exhibiting characteristics similar to conventional solid waste found in households [ 2 ]. World Health Organization (WHO) recommends that appropriate colour-coded waste receptacles be available in all medical and other waste-producing areas [ 3 ].
Solid waste produced in the course of healthcare activities carries a higher potential for infection and injury than any other type of waste. Improper disposal of sharps waste increases the risk of disease transmission among health facility workers and general populations [ 1 ]. Inadequate and inappropriate handling of healthcare waste may have serious public health consequences and a significant environmental impact. The World Health Organization (2014) guidelines also include the following guidance for hand washing and the use of alcohol-based hand rubs: Wash hands before starting work, before entering an operating theatre, before eating, after touching contaminated objects, after using a toilet, and in all cases where hands are visibly soiled [ 4 ].
Among the infectious waste category, sharps waste is the most hazardous waste because of its ability to puncture the skin and cause infection [ 3 ]. Accidents or occurrences, such as near misses, spills, container damage, improper waste segregation, and incidents involving sharps, must be reported promptly to the waste management officer or an assigned representative [ 5 ].
Africa is facing a growing waste management crisis. While the volumes of waste generated in Africa are relatively small compared to developed regions, the mismanagement of waste in Africa already impacts human and environmental health. Infectious waste management has always remained a neglected public health problem in developing countries, resulting in a high burden of environmental pollution affecting the general masses. In Ethiopia, there is no updated separate regulation specific to healthcare waste management in the country to enforce the proper management of solid HCW [ 6 ].
In Ethiopia, like other developing countries, healthcare waste segregation practice was not given attention and did not meet the minimum HCWM standards, and it is still not jumped from paper. Previous study reveals that healthcare waste generation rates are significantly higher than the World Health Organization threshold, which ranges from 29.5–53.12% [ 7 , 8 ]. In Meneilk II Hospital, the proportion of infectious waste was 53.73%, and in the southern and northern parts of Ethiopia, it was 34.3 and 53%, respectively. Generally, this figure shows a value 3 to 4 times greater than the threshold value recommended by the World Health Organization [ 7 ].
Except for sharp wastes, segregation practice was poor, and all solid wastes were collected without respecting the colour-coded waste disposal system [ 9 ]. The median waste generation rate was found to vary from 0.361- 0.669 kg/patient/day, comprising 58.69% non-hazardous and 41.31% hazardous wastes. The amount of waste generated increased as the number of patients flow increased. Public hospitals generated a high proportion of total healthcare waste (59.22%) in comparison with private hospitals (40.48) [ 10 ]. The primary SHCW treatment and disposal mechanism was incineration, open burning, burring into unprotected pits and open dumping on municipal dumping sites as well as in the hospital backyard. Carelessness, negligence of the health workers, patients and cleaners, and poor commitment of the facility leaders were among the major causes of poor HCWM practice in Ethiopia [ 9 ]. This study aimed to investigate solid healthcare waste management practices and develop guidelines to improve solid healthcare waste management practices in Ethiopia.
The setting for this study was all health facilities found in Hossaena town, which is situated 232 kms from the capital city of Ethiopia, Addis Ababa, and 165 kms from the regional municipality of Hawasa. The health facilities found in the town were one university hospital, one private surgical centre, three government health centres, 17 medium clinics, and 19 small clinics were available in the city and; health facility workers who have direct contact with generating and disposal of HCW and those who are responsible as a manager of health facilities found in Hossaena town are the study settings. All health facilities except drug stores and health facility workers who have direct contact with healthcare waste generation participated in this study.
A mixed-method study design was used. For the quantitative part of this study, all healthcare workers who have direct contact with healthcare waste management practice participated in this study, and one focus group discussion from each health facility was used. Both of the study participants were taken from the same population. All health facility workers who have a role in healthcare waste management practice were included in the quantitative part of this study. The qualitative data collection phase used open-ended interviews, focus group discussions, and visual material analysis like posters and written materials. All FGDs were conducted by the principal investigator, one moderator, and one note-taker, and it took 50 to 75 min. 4–6 participants participated in each FGD.
According to Elizabeth (2018: 5), cited by Creswell and Plano (2007: 147), the mixed method is one of the research designs with philosophical assumptions as well as methods of inquiry. As a method, it focuses on collecting, analyzing, and mixing both quantitative and qualitative data in a single study. As a methodology, it involves philosophical assumptions guiding the direction of the collection and analysis and combining qualitative and quantitative approaches in many phases of the research project. The central premise is that using qualitative and quantitative approaches together provides a better understanding of the research problems than either approach alone.
The critical assumption of the concurrent mixed methods approach in this study is that quantitative and qualitative data provide different types of information, often detailed views of participants’ solid waste management practice qualitatively and scores on instruments quantitatively, and together, they yield results that should be the same. In this approach, the researcher collected quantitative and qualitative data almost simultaneously and analyzed them separately to cross-validate or compare whether the findings were similar or different between the qualitative and quantitative information. Concurrent approaches to the data collection process are less time-consuming than other types of mixed methods studies because both data collection processes are conducted on time and at the same visit to the field [ 11 ].
The data collection involves collecting both quantitative and qualitative data simultaneously. The quantitative phase of this study assessed three components. Health care waste segregation practice, the availability of waste segregation equipment for HCW segregation, temporary storage facilities, transportation for final disposal, and disposal facilities data were collected using a structured questionnaire and observation of HCW generation. Recycling or re-using practice, waste treatment, the availability of the HCWM committee, and training data were collected.
The qualitative phase of the data collection for this study was employed by using focus group discussions and semi-structured interviews about SHCWMP. Two focus group discussions (FGD) from each health facility were conducted in the government health facilities, one at the administrative level and one at the technical worker level, and one FGD was conducted for all private health facilities because of the number of available health facility workers. Each focus group has 4–6 individuals.
In this study, the qualitative and the quantitative data provide different information, and it is suitable for this study to compare and contrast the findings of the two results to obtain the best understanding of this research problem.
The quantitative data were entered into Epi data version 3.1 to minimize the data entry mistakes and exported to the statistical package for social science SPSS window version 27.0 for analysis. A numeric value was assigned to each response in a database, cleaning the data, recoding, establishing a codebook, and visually inspecting the trends to check whether the data were typically distributed.
Data were analyzed quantitatively by using relevant statistical tools, such as SPSS. Descriptive statistics and the Pearson correlation test were used for the bivariate associations and analysis of variance (ANOVA) to compare the HCW generation rate between private and government health facilities and between clinics, health centres and hospitals in the town. Normality tests were performed to determine whether the sample data were drawn from a normally distributed population.
The Shapiro–Wilk normality tests were used to calculate a test statistic based on the sample data and compare it to critical values. The Shapiro–Wilk test is a statistical test used to assess whether a given sample comes from a normally distributed population. The P value greater than the significance level of 0.05 fails to reject the null hypothesis. It concludes that there is not enough evidence to suggest that the data does not follow the normal distribution. Visual inspection of a histogram, Q-Q plot, and P-P plot (probability-probability plot) was assessed.
Bivariate (correlation) analysis assessed the relationships between independent and dependent variables. Then, multiple linear regression analysis was used to establish the simple correlation matrices between different variables for investigating the strength relationships of the study variables in the analysis. In most variables, percentages and means were used to report the findings with a 95% confidence interval. Open-ended responses and focused group findings were undertaken by quantifying and coding the data to provide a thematic narrative explanation.
Appropriate and scientific care was taken to maintain the data quality before, during, and after data collection by preparing the proper data collection tools, pretesting the data collection tools, providing training for data collectors, and proper data entry practice. Data were cleaned on a daily basis during data collection practice, during data entry, and before analysis of its completeness and consistency.
Data analysis in a concurrent design consists of three phases. First, analyze the quantitative database in terms of statistical results. Second, analyze the qualitative database by coding the data and collapsing the codes into broad themes. Third comes the mixed-method data analysis. This is the analysis that consists of integrating the two databases. This integration consists of merging the results from both the qualitative and the quantitative findings.
Descriptive analysis was conducted to describe and summarise the data obtained from the samples used for this study. Reliability statistics for constructs, means and modes of each item, frequencies and percentage distributions, chi-square test of association, and correlations (Spearman rho) were used to portray the respondents’ responses.
All patient care-providing health facilities were included in this study, and the generation rate of healthcare waste and composition assessed the practice of segregation, collection, transportation, and disposal system was observed quantitatively using adopted and adapted structured questionnaires. To ensure representativeness, various levels of health facilities like hospitals, health centres, medium clinics, small clinics and surgical centres were considered from the town. All levels of health facilities are diagnosing, providing first aid services and treating patients accordingly.
The hospital and surgical centre found in the town provide advanced surgical service, inpatient service and food for the patients that other health facilities do not. The HCW generation rate was proportional to the number of patients who visited the health facilities and the type of service provided. The highest number of patients who visited the health facilities was in NEMMCSH; the service provided was diverse, and the waste generation rate was higher than that of other health facilities. About 272, 18, 15, 17, and 20 average patients visited the health facilities daily in NEMMCSH: government health centres, medium clinics, small clinics, and surgical centres. Paper and cardboard (141.65 kg), leftover food (81.71 kg), and contaminated gloves (42.96 kg) are the leading HCWs generated per day.
A total of 556 individual respondents from sampled health facilities were interviewed to complete the questionnaire. The total number of filled questionnaires was 540 (97.1) from individuals representing these 41 health facilities.
The principal investigator observed the availability of handwashing facilities near SHCW generation sites. 17(3.1%) of health facility workers had hand washing facilities near the health care waste generation and disposal site. Furthermore,10 (3.87%), 2 (2.1%), 2 (2.53%), 2 (2.1%), 1 (6.6%) of health facility workers had the facility of hand washing near the health care waste generation site in Nigist Eleni Mohamed Memorial Comprehensive Specialized Hospital (NEMMCSH), government health centres, medium clinics, small clinics, and surgical centre respectively. This finding was nearly the same as the study findings conducted in Myanmar; the availability of hand washing facilities near the solid health care waste generation was absent in all service areas [ 12 ]. The observational result was convergent with the response of facility workers’ response regarding the availabilities of hand washing facilities near to the solid health care waste generation sites.
The observational result was concurrent with the response of facility workers regarding the availability of hand-washing facilities near the solid health care waste generation sites.
The availability of personal protective equipment (PPE) was checked in this study. Three hundred ninety-two (72.6%) of the respondents agree on the facility’s availability of one or more personal protective equipment (PPE). The availability of PPEs in different levels of health facilities shows 392 (72.6%), 212 (82.2%), 56 (58.9%), 52 (65.8%), 60 (65.2%), 12 (75%) health facility workers in NEMMCSH, government health centres, medium clinics, small clinics, and surgical centres respectively agree to the presence of personal protective equipment in their department. The analysis further shows that the availability of masks for healthcare workers was above the mean in NEMMCSH and surgical centres.
Focus group participants indicated that health facilities did not volunteer to supply Personal protective equipment (PPEs) for the cleaning staff.
“We cannot purchase PPE by ourselves because of the salary paid for the cleaning staff.”
Cost inflation and the high cost of purchasing PPEs like gloves and boots are complained about by all (41) health facility owners.
“the reason for the absence of some of the PPEs like boots, goggles, and shortage of disposable gloves are owing to cost inflation from time to time and sometimes absent from the market is the reason why we do not supply PPE to our workers.”
Using essential personal protective equipment (PPEs) based on the risk (if the risk is a splash of blood or body fluid, use a mask and goggles; if the risk is on foot, use appropriate shoes) is recommended by the World Health Organization [ 13 ]. The mean availability of gloves in health facilities was 343 (63.5% (95% CI: 59.3–67.4). Private health institutions are better at providing gloves for their workers, 67.1%, 72.8%, and 62.5% in medium clinics, small clinics, and surgical centres, respectively, which is above the mean.
Research participants agree that.
‘‘ there is a shortage of gloves to give service in Nigist Eleni Mohamed Memorial Comprehensive Specialized Hospital (NEMMCSH) and government health centres .’’
Masks are the most available personal protective equipment for health facility workers compared to others. 65.4%, 55.6%, and 38% of the staff are available with gloves, plastic aprons and boots, respectively.
The mean availability of masks, heavy-duty gloves, boots, and aprons was 71.1%, 65.4%, 38%, and 44.4% in the study health facilities. Health facility workers were asked about the availability of different personal protective equipment, and 38% of the respondents agreed with the presence of boots in the facility. Still, the qualitative observational findings of this study show that all health facility workers have no shoes or footwear during solid health care waste management practice.
SHCW segregation practice was checked by observing the availability of SHCW collection bins in each patient care room. Only 4 (1.7%) of the room’s SHCW bins are collected segregated (non-infectious wastes segregated in black bins and infectious wastes segregated in yellow bins) based on the World Health Organization standard. Colour-coded waste bins, black for non-infectious and yellow for infectious wastes, were available in 23 (9.6%) rooms. 90% of the sharp containers were reusable, and 100% of the waste storage bins were plastic buckets that were easily cleanable. Only 6.7% of the waste bins were pedal operated and adequately covered, and the rest were fully opened, or a tiny hole was prepared on the container’s cover. All of the healthcare waste disposal bins in each health facility and at all service areas were away from the arm’s reach distance of the waste generation places, and this is contrary to World Health Organization SHCWM guidelines [ 13 ]. The observation result reveals that the reason for the above result was that medication trolleys were not used during medication or while healthcare providers provided any health services to patients.
Most medical wastes are incinerated. Burning solid and regulated medical waste generated by health care creates many problems. Medical waste incinerators emit toxic air pollutants and ash residues that are the primary source of environmental dioxins. Public concerns about incinerator emissions and the creation of federal regulations for medical waste incinerators are causing many healthcare facilities to rethink their choices in medical waste treatment. Health Care Without Harm [ 14 ], states that non-incineration treatment technologies are a growing and developing field. The U.S. National Academy of Science 2000 argued that the emission of pollutants during incineration is a potential risk to human health, and living or working near an incineration facility can have social, economic, and psychological effects [ 15 ].
The incineration of solid healthcare waste technology has been accepted and adopted as an effective method in Ethiopia. Incineration of healthcare waste can produce secondary waste and pollutants if the treatment facilities are not appropriately constructed, designed, and operated. It can be one of the significant sources of toxic substances, such as polychlorinated dibenzo-dioxins/dibenzofurans (PCDD/ PCDF), polyvinyl chloride (PVC), hexachlorobenzenes and polychlorinated biphenyls, and dioxins and furans that are known as hazardous pollutants. These pollutants may have undesirable environmental impacts on human and animal health, such as liver failure and cancer [ 15 , 16 ].
All government health facilities (4 in number) used incineration to dispose of solid waste. 88.4% and 100% of the wastes are incinerated in WUNEMMCSH and government health centres. This finding contradicts the study findings in the United States of America and Malaysia, in which 49–60% and 59–60 were incinerated, respectively, and the rest were treated using other technologies [ 15 , 16 ].
World Health Organization (2014:45) highlighted those critical elements of the appropriate operation of incinerators include effective waste reduction and waste segregation, placing incinerators away from populated areas, satisfactory engineered design, construction following appropriate dimensional plans, proper operation, periodic maintenance, and staff training and management are mandatory.
Solid waste collection times should be fixed and appropriate to the quantity of waste produced in each area of the health care facility. General waste should not be collected simultaneously or in the same trolley as infectious or hazardous wastes. The collection should be done daily for most wastes, with collection timed to match the pattern of waste generation during the day [ 13 ].
SHCW segregation practices were observed for 240 rooms in 41 health facilities that provide health services in the town. In government health centres, medium clinics, small clinics, and surgical centres, SHCW segregation practice was not based on the World Health Organization standard. All types of solid waste were collected in a single container near the generation area, and there were no colour-coded SHCW storage dust bins. Still, in NEMMCSH, in most of the service areas, colour-coded waste bins are available, and the segregation practice was not based on the standard. Only 3 (10%) of the dust bins collected the appropriate wastes according to the World Health Organization standard, and the rest were mixed with infectious and non-infectious SHCW.
Table 1 below shows health facility managers were asked about healthcare waste segregation practices, and 9 (22%) of the facility leaders responded that there is an appropriate solid healthcare waste segregation practice in their health facilities. Still, during observation, only 4 (1.7%) of the rooms in two (4.87%) of the facilities, SHCW bins collected the segregated wastes (non-infectious wastes segregated at the black bin and infectious wastes segregated at yellow bin) based on the world health organization standard. The findings of this study show there is a poor segregation practice, and all kinds of solid wastes are collected together.
In 40 (97.56%) health facilities, infectious wastes were collected daily from the waste generation areas to the final disposal points. During observation in one of the study health facilities, infectious wastes were not collected daily and left for days. Utility gloves, boots, and aprons are not available for cleaning staff to collect and transport solid healthcare wastes in all study health facilities. 29.26% of the facilities’ cleaning staff have a face mask, and 36.5% of the facilities remove waste bins from the service area when 3/4 full, and the rest were not removed or replaced with new ones. There is a separate container only in 2 health facilities for infectious and non-infectious waste segregation practice, and the rest were segregated and collected using single and non-colour coded containers.
At all of the facilities in the study area, SHCW was transported from the service areas to the disposal site were transported manually by carrying the collection container and there is no trolley for transportation. This finding was contrary to the study findings conducted in India, which show segregated waste from the generation site was being transported through the chute to the carts placed at various points on the hospital premises by skilled sanitary workers [ 17 ].
Only 2 out of 41 health facilities have temporary solid waste storage points at the facility. One of the temporary storage places was clean, and the other needed to be properly cleaned and unsightly. Two (100%) of the temporary storage areas are not fenced and have no restriction to an authorized person. Temporary storage areas are available only in two health facilities that are away from the service provision areas.
Observational findings revealed that pre-treatment of SHCW before disposal was not practised at all study health facilities. 95% of the facilities have no water supply for hand washing during and after solid healthcare waste generation, collection, and disposal.
The United States Agency estimated sharp injuries from medical wastes to health professionals and sanitary service personnel for toxic substances and disease registry. Most of the injuries are caused during the recapping of hypodermic needles before disposal into sharps containers [ 13 ]. Nearly half of the respondents, 245 (51.5%), are recapping needles after providing an injection to the patient. Recapping was more practised in NEMMCSH and surgical centres, which is 57.5% and 57.5%, respectively. In government health centres, medium clinics, and surgical centres, the recapping of used needles was practised below the mean, which is 47.9%, 48, and 43.8%, respectively. This finding was reasonable compared to the study findings of Doylo et al. [ 18 ] in western Ethiopia, where 91% of the health workers are recapping needles after injection [ 18 ]. The research finding shows that there is no significant association P-value of 0.82 between the training and recapping of needles after injection.
“The personal responsibilities of patients and visitors on solid HCW disposal should be explained to help appropriate safe waste management practice and maintain good hygiene .” “Providing waste management training and creating awareness are the two aspects of improving SHCW segregation practice.” “Training upgrades and creates awareness on hygiene for all workers.”
Sharp waste collection practices were observed in 240 rooms in the study health facilities, and 9.2% of the rooms used disposable sharp containers.
Sixty per cent (60%), 13.3%, 8.24%, and 15.71% of the sharps containers in NEMMCSH, government health centres, medium clinics, and small clinics, respectively, were using disposable sharps containers; sharps were disposed together with the sharps container, and surgical centre was using reusable sharp collection container. All disposable sharps containers in medium and small clinics used non-puncture-resistant or simple packaging carton boxes. 60% and 13.3% of the disposable sharps containers in NEMMCSH and the government health centre use purposefully manufactured disposable safety boxes.
Needle sticks injury reporting and occurrence
A total of 70 injuries were reported to the health facility manager in the last one year, and 44 of the injuries were reported by health professionals. The rest of the injuries were reported by supportive staff. These injuries were reported from 35 health facilities, and the remaining six health facilities did not report any cases of injury related to work; see Tables 2 and 3 below.
Accidents or incidents, including near misses, spillages, damaged containers, inappropriate segregation, and any incidents involving sharps, should be reported to the waste-management officer. Accidental contamination must be notified using a standard-format document. The cause of the accident or incident should be investigated by the waste-management officer (in case of waste) or another responsible officer, who should also take action to prevent a recurrence [ 13 ]. Two hundred seventy-one (50.2% (CI: 45.7–54.6) of the respondents agree that satisfactory procedures are available in case of an accident, while the remaining 269 (49.8%( CI: 45.4–54.3) of respondents do not agree on the availability of satisfactory procedures in case of an accident, see Table 4 below. The availability of satisfactory procedures in case of an accident is above the mean in medium clinics, which is 60.8%. 132(24.4%) of the staff are pricked by needle stick injury while providing health services. Nearly half of the respondents, 269 (49.8%), who have been exposed to needle stick injury do not get satisfactory procedures after being pricked by a needle, and those who have not been stung by a needle stick injury for the last year. 204 (37.8%) disagree with the presence of satisfactory procedures in the case of a needle stick injury. In NEMMCSH, 30.2% of the research participants were pricked by needle stick injury within one year of period, and 48.8% of those who were stung by needle stick injuries did not agree upon the presence of satisfactory procedures in case of needle stick injuries in the study hospital. 17.9% and 49.5%, 24.1% and 60.8%, 7.6% and 50% of the respondents are pricked by needle sticks, and they disagree on the availability of satisfactory procedures in case of accidents, respectively, in government health centres, medium clinics, small clinics, and surgical centre respectively.
One hundred seventy-seven (32.7% (CI:29.1–37) respondents were exposed to needle stick injury while working in the current health facilities. One hundred three (58.1%) and 26 (32.9%) needle stick injuries were reported from WUNEMMCSH and medium clinics, which is above the mean. One hundred thirty-two(24.7% (95%CI:20.7–28.1) of the respondents are exposed to needle stick injury within one year of the period. Seventy-eight(30.2%), 17 (17.9%), 19 (24.1%), 15 (16.3%), 3 (18.8%) of the staff are injured by needle sticks from NEMMCSH, government health centres, medium clinics, small clinics, and surgical centre staffs respectively within one year of service.
The mean availabilities of satisfactory procedures in case of accidents were 321 (59.4% (CI:55.4–63.7). Out of this, 13.7% of the staff is injured by needle sticks within one year before the survey. Except in NEMMCSH, the mean availabilities of satisfactory procedures were above the mean, which is 50%, 60%, 77.2%, 66.3%, and 81.3% in NEMMCSH, government health centres, medium clinics, small clinics, and surgical centres respectively.
Table 5 below shows that Hepatitis B, COVID-19, and tetanus toxoid vaccinations are the responses of the research participants to an open-ended question on which vaccine they took. The finding shows that 220 (40.8%) of the respondents were vaccinated to prevent themselves from health facility-acquired infection. One hundred fifty-six (70.9%) of the respondents are vaccinated to avoid themselves from Hep B infection. Fifty-nine (26%0.8) of the respondents were vaccinated to protect themselves from two diseases that are Hep B and COVID-19.
Appropriate health care waste management practice was assessed by using 12 questions: availability of colour-coded waste bins, foot-operated dust bins, elbow or foot-operated hand washing basin, personal protective equipment, training, role and responsibility of the worker, the presence of satisfactory procedures in case of an accident, incinerator, vaccination, guideline, onsite treatment, and the availability of poster. The mean of appropriate healthcare waste management practice was 55.58%. The mean of solid health care waste management practice based on the level of health facilities was summed and divided into 12 variables to get each health facility’s level of waste management practice. 64.9%, 45.58%, 49%, 46.9%, and 51.8% are the mean appropriate health care waste management practices in NEMMCSH, government health centres, medium clinics, small clinics, and surgical centres, respectively. In NEMMCSH, the practice of solid healthcare waste management shows above the mean, and the rest was below the mean of solid healthcare waste management practice.
Solid waste treatment before disposal was not practised at all study health facilities. There is an incineration practice at all of the study health facilities, and the World Health Organization 2014 recommended three types of incineration practice for solid health care waste management: dual-chamber starved-air incinerators, multiple chamber incinerators, and rotary kilns incinerators. Single-chamber, drum, and brick incinerators do not meet the best available technique requirements of the Stockholm Convention guidelines [ 13 ]. The findings of this study show that none of the incinerators found in the study health facilities meet the minimum standards of solid healthcare waste incineration practice, and they need an air inlet to facilitate combustion. Eleven (26.82%) of the health facilities have an ash pit to dispose of burned SHCW; the majority, 30 (73.17%), dispose of the incinerated ash and burned needles in the municipal waste disposal site. In one out of 11 health facilities with an ash pit, one of the incinerators was built on the ash pit, and the incinerated ashes were disposed of in the ash pit directly. Pre-treatment of SHCW before disposal was not practised at all health facilities; see Table 6 below.
All government health facilities use incineration to dispose of solid waste. 88.4% and 100% of the solid wastes are incinerated in WUNEMMCS Hospital and government health centres, respectively. This finding was not similar to the other studies because other technologies like autoclave microwave and incineration were used for 59–60% of the waste [ 15 ]. Forty-one (100%) of the study facilities were using incinerators, and only 5 (12.19%) of the incinerators were constructed by using brick and more or less promising than others for incinerating the generated solid wastes without considering the emitting gases into the atmosphere and the residue chemicals and minerals in the ashes.
Research participants’ understanding of the environmental friendliness of health care waste management practice was assessed, and the result shows that more than half, 312(57%) of the research participants do not agree on the environmental friendliness of the waste disposal practices in the health facilities. The most disagreement regarding environmental friendliness was observed in NEMMCSH; 100 (38.8%) of the participants only agreed the practice was environmentally friendly of the service. Forty-four (46.3%), 37 (46.8%), 40 (43.5%), and 7 (43.8%) of the participants agree on the environmental friendliness of healthcare waste management practice in government health centres, medium clinics, small clinics, and surgical centres, respectively.
One hundred twenty-five (48.4%) and 39(42.4%) staff are trained in solid health care waste management practice in NEMMCSH and small clinic staff, respectively; this result shows above the mean. Twenty-seven (28.4%), 30 (38%), and 4 (25%) of the staff are trained in health care waste management practice in Government health centres, medium clinics, and surgical centres, respectively. The training has been significantly associated with needle stick injury, and the more trained staff are, the less exposed to needle stick injury. One hundred ninety-six (36.4%) of the participants answered yes to the question about the availability of trainers in the institution. 43.8% of the NEMMCSH staff agreed on the availability of trainers on solid health care waste management, which is above the mean, and 26.3%, 31.6%, 31.5%, and 25% for the government health centres, medium clinics, small clinics, and surgical centre respectively, which is below the mean.
Trained health professionals are more compliant with SHCWM standards, and the self-reported study findings of this study show that 41.7% (95%CI:37.7–46) of the research participants are trained in health care waste management practice. This finding was higher compared to the study findings of Sahiledengle in 2019 in the southeast of Ethiopia, shows 13.0% of healthcare workers received training related to HCWM in the past one year preceding the study period and significantly lower when compared to the study findings in Egypt which is 71% of the study participants were trained on SHCWM [ 8 , 19 , 20 ].
Three out of four government health facility leaders, 17 (45.94%) of private health facility leaders/owners of the clinic and 141 FGD participants complain about the absence of some PPEs like boots and aprons to protect themselves from infectious agents.
‘ ‘Masks, disposable gloves, and changing gowns are a critical shortage at all health facilities.’’
Cleaners in private health facilities are more exposed to infectious agents because of the absence of personal protective equipment. Except for the cleaning staff working in the private surgical centre, all cleaning staff 40 (97.56) of the health facilities complain about the absence of changing gowns and the fact that there are no boots in the facilities.
Cost inflation and the high cost of purchasing PPEs like gloves and boots are complained by all of (41) the health facility owners and the reason for the absence of some of the PPEs like boots, goggles, and shortage of disposable gloves. Sometimes, absence from the market is the reason why we do not supply PPE to our workers.
Thirty-four (82.92%) of the facility leaders are forwarded, and there is a high expense and even unavailability of some of the PPEs, which are the reasons for not providing PPEs for the workers.
‘‘Medical equipment and consumables importers and whole sellers are selective for importing health supplies, and because of a small number of importers in the country and specifically, in the locality, we can’t get materials used for health care waste management practice even disposable gloves. ’’
One of the facility leaders from a private clinic forwarded that before the advent of COVID-19 -19) personal protective equipment was more or less chip-and-get without difficulty. Still, after the advent of the first Japanese COVID-19 patient in Ethiopia, people outside the health facilities collect PPEs like gloves and masks and storing privately in their homes.
‘‘PPEs were getting expensive and unavailable in the market. Incinerator construction materials cost inflation, and the ownership of the facility building are other problems for private health facilities to construct standard incinerators.’’
For all of the focus group discussion participants except in NEMMCSH and two private health facilities, covered and foot-operated dust bins were absent or in a critical shortage compared to the needed ones.
‘‘ Waste bins are open and not colour-coded. The practice attracts flies and other insects. Empty waste bins are replaced without cleaning and disinfecting by using chlorine solution.’’ “HCW containers are not colour-coded, but we are trying to label infectious and non-infectious in Amharic languages.”
Another issue raised during focus group discussions is incineration is not the final disposal method. It needs additional disposal sites, lacks technology, is costly to construct a brick incinerator, lacks knowledge for health facility workers, shortage of man powers /cleaners, absence of environmental health professionals in health centres and all private clinics, and continues exposure to the staff for needle stick injury, foully smell, human scavengers, unsightly, fire hazard, and lack of water supply in the town are the major teams that FGD participants raise and forwarded the above issue as a problem to improve SHCWMP.
Focus group participants, during the discussion, raised issues that could be more comfortable managing SHCWs properly in their institution. Two of the 37 private health facilities are working in their own compound, and the remaining 35 are rented; because of this, they have difficulty constructing incinerators and ash removal pits and are not confident about investing in SHCWM systems. Staff negligence and involuntary abiding by the rules of the facilities were raised by four of the government health facilities, and it was difficult to punish those who violated the healthcare waste management rules because the health facility leaders were not giving appropriate attention to the problem.
Focus group participants forwarded recommendations on which interventions can improve the management of SHCW, and recommendations are summarised as follows:
“PPE should be available in quality and quantity for all health facility workers who have direct contact with SHCW.” “Scientific-based waste management technologies should be availed for health facilities.” “Continuous induction HCW management training should be provided to the workers. Law enforcement should be strengthened.” “Communal HCW management sites should be availed, especially for private health facilities.” “HCWM committee should be strengthened.” “Non-infectious wastes should be collected communally and transported to the municipal SHCW disposal places.” “Leaders should be knowledgeable on the SHCWM system and supervise the practice continuously.” “Patient and client should be oriented daily about HCW segregation practice.” “Regulatory bodies should supervise the health facilities before commencing and periodically between services .”
The above are the themes that FGD participants discussed and forwarded for the future improvements of SHAWMP in the study areas.
Other issues raised during FGDs were health facilities’ lack of water supply. World Health Organization (2014: 89) highlights that water supply for the appropriate waste management system should be mandatory at any time in all health service delivery points.
Thirty-nine (95.12%) of the health facilities complain about the absence of water supply to improve HCW management practices and infection prevention and control practices in the facilities.
“We get water once per week, and most of the time, the water is available at night, and if we are not fetching as scheduled, we can’t get water the whole week”.
In this research, only those who have direct contact have participated in this study, and 434 (80.4%) of the respondents agree they have roles and responsibilities for appropriate solid health care waste management practice. The rest, 19.6%, do not agree with their commitment to manage health care wastes properly, even though they are responsible. Health facility workers in NEMMCSH and medium clinics know their responsibilities better than others, and their results show above the mean. 84.5%, 74.5%, 81%, 73.9% and 75% in NEMMCSH, Government health centres, medium clinics, small clinics, and surgical centres, respectively.
Establishing a policy and a legal framework, training personnel, and raising public awareness are essential elements of successful healthcare waste management. A policy can be viewed as a blueprint that drives decision-making at a political level and should mobilize government effort and resources to create the conditions to make changes in healthcare facilities. Three hundred and seventy-four (69.3%) of the respondents agree with the presence of any solid healthcare waste management policy in Ethiopia. The more knowledge above the mean (72.9%) on the presence of the policy is reported from NEMMCSH.
Self-reported level of knowledge on what to do in case of an accident revealed that 438 (81.1% CI: 77.6–84.3%) of the respondents knew what to do in case of an accident. Government health centre staff and medium clinic staff’s knowledge about what to do in case of an accident was above the mean (88.4% and 82.3%), respectively, and the rest were below the mean. The action performed after an occupational accident revealed that 56 (35.7%) of the respondents did nothing after any exposure to an accident. Out of 56 respondents who have done nothing after exposure, 47 (83.92%) of the respondents answered yes to their knowledge about what to do in case of an accident. Out of 157 respondents who have been exposed to occupational accidents, only 59 (37.6%) of the respondents performed the appropriate measures, 18 (11.5%), 9 (5.7%), 26 (16.6%), 6 (3.8%) of the respondents are taking prophylaxis, linked to the incident officer, consult the available doctors near to the department, and test the status of the patient (source of infection) respectively and the rest were not performing the scientific measures, that is only practising one of the following practices washing the affected part, squeezing the affected part to remove blood, cleaning the affected part with alcohol.
Health facility workers’ understanding of solid health care waste management practices was assessed by asking whether the current SHCWM practice needs improvement. Four hundred forty-nine (83.1%) health facility workers are unsatisfied with the current solid waste management practice at the different health facility levels, and they recommend changing it to a scientific one. 82.6%, 87.4%, 89.9%, 75%, and 81.3% of the respondents are uncomfortable or need to improve solid health care waste management practices in NEMMCSH, government health centres, medium clinics, small clinics, and surgical centres, respectively.
Lack of safety box, lack of colour-coded waste bins, lack of training, and no problems are the responses to the question problems encountered in managing SHCWMP. Two Hundred and Fifty (46.92%) and 232 (42.96%) of the respondents recommend the availability of safety boxes and training, respectively.
Four or 9.8% of the facilities have infection prevention and control (IPC) teams in the study health facilities. This finding differed from the study in Pakistan, where thirty per cent (30%) of the study hospitals had HCWM or infection control teams [ 21 ]. This study’s findings were similar to those conducted in Pakistan by Khan et al. [ 21 ], which confirmed that the teams were almost absent at the secondary and primary healthcare levels [ 20 ].
The availability of health care waste management policy report reveals that 69.3% (95% CI: 65.4–73) of the staff are aware of the presence of solid health care waste management policy in the institution. Availability of health care waste management policy was 188 (72.9%), 66 (69.5%), 53 (677.1%), 57 (62%), 10 (62.5%) in NEMMCSH, Government health centres, medium clinics, small clinics, and surgical centre respectively. Healthcare waste management policy availability was above the mean in NEMMCSH and government health centres; see Table 6 below.
Open-ended responses on the SHCWM practice of health facility workers were collected using the prepared interview guide, and the responses were analyzed using thematic analysis. All the answered questions were tallied on the paper and exported to Excel software for thematic analysis.
The study participants recommend.
“appropriate segregation practice at the point of generation” "health facility must avail all the necessary supplies that used for SHCWMP, punishment for those violating the rule of SHCWMP",
“waste management technologies should be included in solid waste management guidelines, and enforcement should be strengthened.”
The availability of written national or adopted/adapted SHCWM policies was observed at all study health facilities. Twenty eight (11.66%) of the rooms have either a poster or a written document of the national policy document. However, all staff working in the observed rooms have yet to see the inside content of the policy. The presence of the policy alone cannot bring change to SHCWMP. This finding shows that the presence of policy in the institution was reasonable compared to the study findings in Menelik II hospital in Addis Ababa, showing that HCWM regulations and any applicable facility-based policy and strategy were not found [ 22 ]. The findings of this study were less compared to the study findings in Pakistan; 41% of the health facilities had the policy document or internal rules for the HCWM [ 21 ].
Focus group participants have forwarded recommendations on which interventions can improve the management of SHCW, and recommendations are summarised as follows.
‘‘Supplies should be available in quality and quantity for all health facility workers with direct contact with SHCW. Scientific-based waste management technologies should be available for health facilities. Continues and induction health care waste management training should be provided to the workers. Law enforcement should be strengthened. Community healthcare waste management sites should be available, especially for private health facilities. HCWM committee should be strengthened. Non-infectious wastes should be collected communally and transported to the municipal SHCW disposal places. Leaders should be knowledgeable about the SHCWM system and supervise the practice continuously. Patients and clients should be oriented daily about health care waste segregation practices. Regulatory bodies should supervise the health facilities before commencing and periodically in between the service are the themes those FGD participants discussed and forward for the future improvements of SHCWMP in the study areas.’’
The availability of PPEs in different levels of health facilities shows 392 (72.6%), 212 (82.2%), 56 (58.9%), 52 (65.8%), 60 (65.2%), 12 (75%) health facility workers in NEMMCSH, government health centres, medium clinics, small clinics, and surgical centres respectively agree to the presence of personal protective equipment in their department. The availability of PPEs in this study was nearly two-fold when compared to the study findings in Myanmar, where 37.6% of the staff have PPEs [ 12 ].
The mean availability of masks, heavy-duty gloves, boots, and aprons was 71.1%, 65.4%, 38%, and 44.4% in the study health facilities. This finding shows masks are less available in the study health facilities compared to other studies. The availability of utility gloves, boots, and plastic aprons is good in this study compared to the study conducted by Banstola, D in Pokhara Sub-Metropolitan City [ 23 ].
The findings of this study show there is a poor segregation practice, and all kinds of solid wastes were collected together. This finding was similar to the study findings conducted in Addis Ababa, Ethiopia, by Debere et al. [ 24 ] and contrary to the study findings conducted in Nepal and India, which shows 50% and 65–75% of the surveyed health facilities were practising proper waste segregation systems at the point of generation without mixing general wastes with hazardous wastes respectively [ 9 , 17 ].
Ninety percent of private health facilities collect and transport SHCW generated in every service area and transport it to the disposal place by the collection container (no separate container to collect and transport the waste to the final disposal site). This finding was similar to the study findings of Debre Markos’s town [ 25 ]. At all of the facilities in the study area, SHCW was transported from the service areas to the disposal site manually by carrying the collection container, and there was no trolley for transportation. This finding was contrary to the study findings conducted in India, which show segregated waste from the generation site was being transported through the chute to the carts placed at various points on the hospital premises by skilled sanitary workers [ 17 ].
Observational findings revealed that pre-treatment of SHCW before disposal was not practised at all study health facilities. This study was contrary to the findings of Pullishery et al. [ 26 ], conducted in Mangalore, India, which depicted pre-treatment of the waste in 46% of the hospitals [ 26 ]. 95% of the facilities have no water supply for handwashing during and after solid healthcare waste generation, collection, and disposal. This finding was contrary to the study findings in Pakistan hospitals, which show all health facilities have an adequate water supply near the health care waste management sites [ 27 ].
Questionnaire data collection tools show that 129 (23.8%) of the staff needle stick injuries have occurred on health facility workers within one year of the period before the data collection. This finding was slightly smaller than the study findings of Deress et al. [ 25 ] in Debre Markos town, North East Ethiopia, where 30.9% of the workers had been exposed to needle stick injury one year prior to the study [ 25 ]. Reported and registered needle stick injuries in health facilities are less reported, and only 70 (54.2%) of the injuries are reported to the health facilities. This finding shows an underestimation of the risk and the problem, which was supported by the study conducted in Menilik II hospitals in Addis Ababa [ 22 ]. 50%, 33.4%, 48%, 52%, and 62.5% of needle stick injuries were not reported in NEMMCSH, Government health centres, medium clinics, small clinics, and surgical centres, respectively, to the health facility manager.
Nearly 1/3 (177 or 32.7%) of the staff are exposed to needle stick injuries. Needle stick injuries in health facilities are less reported, and only 73 (41.24%) of the injuries are reported to the health facilities within 12 months of the data collection. This finding is slightly higher than the study finding of Deress et al. [ 25 ] in Debere Markos, Ethiopia, in which 23.3% of the study participants had encountered needle stick/sharps injuries preceding 12 months of the data collection period [ 25 ].
Seventy-three injuries were reported to the health facility manager in the last one year, 44 of the injuries were reported by health professionals, and the rest were reported by supportive staff. These injuries were reported from 35(85.3%) health facilities; the remaining six have no report. These study findings were better than the findings of Khan et al. [ 21 ], in which one-third of the facilities had a reporting system for an incident, and almost the same percentage of the facilities had post-exposure procedures in both public and private sectors [ 21 ].
Within one year of the study period, 129 (23.88%) needle stick injuries occurred. However, needle stick injuries in health facilities are less reported, and only 70 (39.5%) of the injuries are reported to the health facilities. These findings were reasonable compared to the study findings of the southwest region of Cameroon, in which 50.9% (110/216) of all participants had at least one occupational exposure [ 28 , 29 ]. This result report shows a very high exposure to needle stick injury compared to the study findings in Brazil, which shows 6.1% of the research participants were injured [ 27 ].
The finding shows that 220 (40.8%) of the respondents were vaccinated to prevent themselves from health facility-acquired infection. One Hundred Fifty-six (70.9%) of the respondents are vaccinated in order to avoid themselves from Hep B infection. Fifty-nine (26%0.8) of the respondents were vaccinated to protect themselves from two diseases that are Hep B and COVID-19. This finding was nearly the same as the study findings of Deress et al. [ 7 ],in Ethiopia, 30.7% were vaccinated, and very low compared to the study findings of Qadir et al. [ 30 ] in Pakistan and Saha & Bhattacharjya India which is 66.67% and 66.17% respectively [ 25 , 30 , 31 ].
The incineration of solid healthcare waste technology has been accepted and adopted as an effective method in Ethiopia. These pollutants may have undesirable environmental impacts on human and animal health, such as liver failure and cancer [ 15 , 16 ]. All government health facilities use incineration to dispose of solid waste. 88.4% and 100% of the wastes are incinerated in WUNEMMCSH and government health centres, respectively. This finding contradicts the study findings in the United States of America and Malaysia, which are 49–60% and 59–60 are incinerated, respectively, and the rest are treated using other technologies [ 15 , 16 ].
All study health facilities used a brick or barrel type of incinerator. The incinerators found in the study health facilities need to meet the minimum standards of solid health care waste incineration practice. These findings were similar to the study findings of Nepal and Pakistan [ 32 ]. The health care waste treatment system in health facilities was found to be very unsystematic and unscientific, which cannot guarantee that there is no risk to the environment and public health, as well as safety for personnel involved in health care waste treatment. Most incinerators are not properly operated and maintained, resulting in poor performance.
All government health facilities use incineration to dispose of solid waste. All the generated sharp wastes are incinerated using brick or barrel incinerators, as shown in Fig. 1 above. This finding was consistent with the findings of Veilla and Samwel [ 33 ], who depicted that sharp waste generation is the same as sharps waste incinerated [ 33 ]. All brick incinerators were constructed without appropriate air inlets to facilitate combustion except in NEMMCSH, which is built at a 4-m height. These findings were similar to the findings of Tadese and Kumie at Addis Ababa [ 34 ].
Barrel and brick incinerators used in private clinic
This is a mixed-method study; both qualitative and quantitative study design, data collection and analysis techniques were used to understand the problem better. The setting for this study was one town, which is found in the southern part of the country. It only represents some of the country’s health facilities, and it is difficult to generalize the findings to other hospitals and health centres. Another limitation of this study was that private drug stores and private pharmacies were not incorporated.
In the study, health facilities’ foot-operated solid waste dust bins are not available for healthcare workers and patients to dispose of the generated wastes. Health facility managers in government and private health institutions should pay more attention to the availability of colour-coded dust bins. Most containers are opened, and insects and rodents can access them anytime. Some of them are even closed (not foot-operated), leading to contamination of hands when trying to open them.
Healthcare waste management training is mandatory for appropriate healthcare waste disposal. Healthcare-associated exposure should be appropriately managed, and infection prevention and control training should be provided to all staff working in the health facilities.
