The role of community health workers in promoting oral health at school settings: A scoping review.

OBJECTIVES: The scoping review aimed to examine the literature on the role of Community Health Workers (CHW) in oral health interventions within school settings. The objectives were to identify the characteristics of school oral health interventions where CHWs played a role; and to assess the outcomes derived from CHW participation in school oral health. METHODS: The scoping review was guided by the Levac et al (2010) framework. Articles selected for this review included all forms of study designs and gray literature. The search strategy included CHW and other non-dental personnel providing oral health activities within schools and the outcomes of these interventions from 1995. Databases included Pubmed, ProQuest, Scopus and EBSCO Host. RESULTS: There were eleven (n = 11) peer reviewed articles included. Only one study in this review related to CHW involvement in school oral health settings. The remaining involved teachers (n = 4), peer learners (n = 3) or a combination of both (n = 3). Characteristics of the interventions ranged from oral health screenings, education, supervised brushing, and community engagements. Three outcomes emerged; widening access to oral health services, acceptability of non-oral health personnel and learners in promoting oral health and improvement of oral health self-care. CONCLUSIONS: The review brought to light the benefits of utilizing non-dental personnel such as teachers and peer learners in augmenting staff capacity for school oral health interventions. In addition, the findings highlighted the need to further research on the feasibility and acceptability of integrating CHW in school oral health settings.

Cost-effectiveness of dental caries prevention strategies in South African schools.

BACKGROUND: In South Africa, an estimated 85% of the population relies on the public sector for oral health services. With poor infrastructure and inadequate personnel, over 80% of children with dental caries remain untreated. To reduce this burden of disease, one key goal is to promote good oral health and address oral diseases through prevention, screening, and treatment among children. While all policies have been proven to be effective in the control and prevention of dental caries, it is unclear which of those strategies provide value for money. This study evaluated five caries preventative strategies in terms of the cost and benefits among South African school children. METHODS: The study uses a hypothetical South African population of school aged learners aged 5-15. The context and insights of the strategies utilized at the schools were informed by data from both grey and published literature. Using Markov modeling techniques, we conducted a cost-effectiveness analysis of Acidulated Phosphate Fluoride (APF) application, atraumatic restorative treatment (ART), sugar-reduction and fissure sealants. Markov model was used to depict the movement of a hypothetical patient cohort between different health states over time. We assessed both health outcomes and costs of various interventions. The health outcome metric was measured as the number of Decayed, Missing, Filled Tooth (DMFT). The net monetary benefit was then used to determine which intervention was most cost-effective. RESULTS: The results showed that school-based caries prevention strategies are cost-effective compared to the status quo of doing nothing. The average cost per learner over the 10-year period ranged from ZAR4380 to approx. ZAR7300 for the interventions considered. The total costs (including screening) associated with the interventions and health outcome (DMFT averted) were: sugar reduction (ZAR91,380, DFMT: 63,762), APF-Gel (ZAR54 million, DMFT: 42,010), tooth brushing (ZAR72.8 million, DMFT: 74,018), fissure sealant (ZAR44.63 million, DMFT: 100,024), and ART (ZAR45 million, DMFT: 144,035). The net monetary benefits achieved for APF-Gel, sugar reduction, tooth brushing, fissure sealant and ART programs were ZAR1.56, ZAR2.45, ZAR2.78, ZAR3.81, and ZAR5.55 billion, respectively. CONCLUSION: Based on the net monetary benefit, ART, fissure sealant and sugar-reduction appear to be the most cost-effective strategies for preventing caries in South Africa. In a resource-scarce setting such as South Africa, where there is no fluoridation of drinking water, this analysis can inform decisions about service packages for oral health.

Perceptions of provincial and district level managers' on the policy implementation of school oral health in South Africa.

BACKGROUND: Although school oral health programmes have been ongoing for years, there is little evidence to show how their policy elements are governed or translated into tangible implementation activities and population outcomes at the district level. The need for such a study is heightened by the persistent burden of oral health conditions and unmet oral treatment needs of South Africa's children. This study therefore sought to describe provincial and district level managers' perceptions of school oral health policy, and to identify gaps and conditions needed for successful policy implementation. METHODS: This was an exploratory qualitative study where eight oral health managers from the Gauteng provincial and district offices were purposively sampled. Data were collected using interviews and a policy review rubric. The 10 Siddiqi governance principles framework was used to guide the data analysis. RESULTS: The managers' perceptions and the policy document review indicated that national policy covered the principles of strategic vision, responsiveness to health needs, equity and inclusivity with clarity; however these principles were not translated consistently by the managers at a local level. Policy gaps were identified in the areas of stakeholder involvement, accountability, reliable information systems and ethical guidelines. Much of the gaps in policy translation were attributed to inadequate human resources and poor communication processes by the national leadership to support district level implementation. CONCLUSIONS: There were inconsistencies in policy awareness and translation in the districts and hence an in-depth review of the policy translation gaps is paramount to its efficient resolution in the context of resource and capacity limitations. Furthermore, optimizing multi-sectoral participation and identifying shared, novel and practical solutions to policy translation impediments is necessary.

Implementation fidelity of school oral health programs at a District in South Africa.

BACKGROUND: It is important that components contributing to success of a program are well understood to ensure better outcomes and strengthen interventions. Hence the purpose of the study was to assess the level of fidelity achieved by school oral health programs in our study district and to determine elements of fidelity that predict the risk of dental decay. METHODS: A cross-sectional study design was utilised. A multistage sampling technique was employed to randomly select 10 schools, two grades in each school were selected and all pupils in the selected grades were included in an oral health examination. Ten oral hygienists were observed and interviewed as they carried out the activities of the program and records were reviewed. Data collection tools included an oral health examination form, and an implementation fidelity checklist. RESULTS: The average level of fidelity obtained was 40% and it was shown to be inversely correlated with levels of decay, as decay was predicted to decrease with increasing levels of fidelity. The fidelity elements that were found to directly predict the outcome of decay included duration (IRR, 0.49; p = 0.02) coverage (IRR, 0.54; p = 008), content (IRR, 1.36; p = 0.03) and age (IRR, 2.14; p = 0.00). Moderating factors of fidelity which indirectly influenced the outcome of decay included facilitation strategy, duration and age. These were predicted to reduce the risk of decay by 92%, 83% and 48% respectively. CONCLUSION: The school oral health programs exhibited high levels of pupil coverage, however, the content of the programs offered was low (28%). Coverage was high in the context of lack of dental assistance and time. Multi-sectoral participation is therefore necessary to re-organise the program for improving implementation fidelity and bringing about quality implementation.

The policy implementation gap of school oral health programmes in Tshwane, South Africa: a qualitative case study.

BACKGROUND: School going children across the world continue to experience high levels of untreated dental diseases. The South African Oral Health policy documents present measures to address the oral health needs of children in school settings, yet the burden of oral disease in the country is over 50% among primary school children. METHODS: Our study therefore sought to assess the implementation of school oral health programmes in Tshwane in line with policy recommendations using the Walt & Gilson policy analysis triangle. A qualitative explanatory case study was undertaken using a combination of data from direct observations and interviews. The case analysis involved assessing the processes of providing school oral health programmes that were offered at 10 schools in Tshwane. The measuring tools included process maps and an interview guide. RESULTS: The results found that policy implementation was affected by poor prior planning, inadequate resources, poor school infrastructure and lack of support from key stakeholders. Furthermore, inconsistencies in policy interpretation by management, coupled with the fact that the oral hygienists were not conversant with the policy hampered delivery of the policy content. The variations in policy implementation observed were often at the discretion of the oral hygienist in response to contextual challenges. CONCLUSION: There was policy and practice misalignment and variations in the processes of implementing oral health programmes across the 10 schools. Hence regular monitoring, evaluation and root cause analysis is recommended for such programmes in order to make informed decisions on contextually relevant and standardised programme modifications.

Oral health promotion in Gauteng: a qualitative study.

INTRODUCTION AND BACKGROUND: One of the aims of the South African Oral Health Promotion Framework is to integrate oral health promotion activities into general health promotion using the Common Risk Factor Approach (CRFA). Though policies have directed that oral health should be integrated into general health promotion in South Africa, little is known about the implementation of the CRFA in daily oral health promotion practice. AIM: This study aimed to assess how health promoters in Gauteng integrate oral health into their general health promotion activities. OBJECTIVES: The objectives were (i) to describe how health promoters undertake health promotion in Gauteng; (ii) to describe how health promoters incorporate oral health promotion into health promotion activities; and (iii) to describe the opportunities and challenges for health promoters in applying the CRFA. METHOD: This was a qualitative study and data were collected using semi-structured interviews. A purposive sample of 10 formally trained health promoters agreed to be interviewed. Thematic analysis was used to analyse the data. RESULTS: Participants' work was centred mostly on healthy lifestyle campaigns and there was little integration of oral health into health promotion activities. While most health promoters had an understanding of the CRFA, this understanding was not common amongst other levels of management. Oral health literacy was low and health promoters perceived few opportunities for using a CRFA when weighed against other priorities such as poverty and HIV/AIDS. CONCLUSION: Currently there is little evidence of integration of oral health into general health promotion activities.
