A novel cadre of community health workers known as village health workers (VHWs) were recruited to create demand for maternal health services in the Nigerian Subsidy Reinvestment Programme (SURE-P/MCH).

Initial working theories and logic maps were developed through literature review and stakeholder engagement; programme theories were developed and tested using focus group discussions and in-depth interviews with various stakeholder groups.

These mechanisms were triggered by interactions of programme-specific contexts and resources such as training and supervision of VHWs by skilled health workers, provision of first aid kits and uniforms, and payments of a monthly stipend. The monthly payment was considered to be the most important motivational factor by VHWs. VHWs used a combination of innovative approaches to create demand for maternity services among pregnant women, and their performance was influenced by health system factors such as organisational capacity and culture, and societal factors such as relationship with the community and community support.</p><p><strong>Conclusion: </strong>This paper highlights important contextual factors and mechanisms for VHW motivation that can be applied to other interventions that seek to strengthen community engagement and demand creation in primary health care.

Methods A qualitative, descriptive-interpretative study using semi-structured individual interviews and focus groups with 40 professionals (GPs, specialists, members of the local steering committee (LSC) and network middle managers) involved in designing and implementing joint training sessions to improve cross-level clinical coordination. The intervention consisted of two forms of joint training sessions for GPs and specialists, implemented through two PAR cycles. Results The PAR approach in designing and implementing joint training sessions led to greater awareness of clinical coordination problems and helped adapting sessions to the local health care context. Study participants highlighted the role of LSC leadership during the PAR process and the importance of ensuring the necessary resources for adopting the intervention. Limited institutional support and differences between joint training sessions affected doctors’ participation and reduced the time available to conduct the sessions. The use of a reflexive method was essential in enhancing doctors’ participation, along with session duration, the facilitator’s role and session content. Conclusions The study provides evidence regarding the contribution of a PAR process to designing and implementing joint training sessions for improving clinical coordination.

Methods Semi-structured interviews were undertaken with 48 members of staff working with older forensic mental health patients in secure inpatient units or the community in England.

Our primary objective was to compare policy wording and categorise any variations identified. Our secondary objective was to explore how any points of variation relate to national guidance. Methods This study entailed documentary analysis of commissioning policies that stipulated criteria for accessing eight elective musculoskeletal procedures. For each procedure, we retrieved policies held by regions with higher and lower rates of clinical activity relative to the national average. Policies were subjected to content and thematic analysis, using constant comparison techniques. Matrices and descriptive reports were used to compare themes across policies for each procedure and derive categories of variation that arose across two or more procedures. National guidance relating to each procedure were identified and scrutinised, to explore whether these provided context for explaining the policy variations. Results Thirty-five policy documents held by 14 geographic regions were included in the analysis. Policies either focused on a single procedure/treatment or covered several procedures/treatments in an all-encompassing document. All policies stipulated criteria that needed to be fulfilled prior to accessing treatment, but there were inconsistences in the evidence cited. Policies varied in recurring ways, with respect to specification of non-surgical treatments and management, requirements around time spent using non-surgical approaches, diagnostic requirements, requirements around symptom severity and disease progression, and use of language, in the form of terms and phrases (‘threshold modifiers’) which could open up or restrict access to care. National guidance was identified for seven of the procedures, but this guidance did not specify criteria for accessing the procedures in question, making direct comparisons with regional policies difficult. Conclusions This, to our knowledge, is the first study to identify recurring ways in which policies for accessing treatment can vary within a single-payer system with universal coverage. The findings raise questions around whether formulation of commissioning policies should receive more central support to promote greater consistency – especially where evidence is uncertain, variable or lacking.","PeriodicalId":15953,"journal":{"name":"Journal of Health Services Research & Policy","volume":"1 1","pages":"190 - 202"},"PeriodicalIF":2.4,"publicationDate":"2022-05-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87179797","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
