Commonly part of broader quality improvement efforts, SS programs are increasingly used in low-and middle-income countries to improve malaria case management. Despite substantial investments and some positive outcomes, little is known about what drives their effectiveness. A realist evaluation was conducted in Tanzania and Benin to explain how, why, and under what circumstances SS programs can improve the facility-based management of uncomplicated malaria in children under five. A program theory was developed through a team-based analysis of empirical data collected in both countries at two time points. Data included 218 in-depth and 12 structured interviews with stakeholders, 154 audits of febrile case management decisions, and four health facility audits. Stakeholder perspectives identified three acceptability mechanisms driving SS program outcomes in the studied contexts: the affective attitude, self-efficacy, and burden of the program as perceived by key actors. The pathway through which these mechanisms were perceived to shape malaria case management (diagnosis and treatment) practices was defined by the 1) extent to which the program was integrated into the public health system; 2) frequency with which SS visits were conducted by appropriate supervisors; 3) degree to which supervisors coached, rather than policed, supervisees; and 4) level of collaboration achieved between supervisees and supervisors. The program actors' perception of the program's effectiveness was also found to be crucial to its sustainability. This study explains the dynamics driving SS program outcomes and underscores the role played by the cognitive and emotional responses of program actors. These insights are likely to be transferable to other settings with similar contexts and can help inform the design, implementation, monitoring, and evaluation of new and ongoing SS programs.</p>","PeriodicalId":12926,"journal":{"name":"Health policy and planning","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143718795","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A total of 111 respondents were interviewed, including 38 doctors, 28 clinical pharmacists, 15 microbiologists, 14 infection prevention and control specialists, 10 experts from medical service departments, and 6 quality improvement experts. A thematic framework analysis was conducted. A common implementation strategy was found among the surveyed hospitals in response to the AMS programs mandated by healthcare authorities. The hospital leadership empowered an AMS team to set AMS-related indicators for each clinical department and each doctor, and adopted core elements of AMS to optimize antimicrobial prescribing. However, the mandatory AMS approach also caused unintended consequences including regulatory circumvention, shift of risk to doctors and patients, and demotivation of healthcare workers. Two key barriers to AMS implementation were identified: 1) poor communication and cooperation between the AMS team and doctors, characterized by a high-power-low-power dynamic within hospital disciplines; and 2) the profit-driven compensation system, which discourages collaboration and resource distribution for AMS implementation. Mandatory AMS programs should intensify AMS training, promote communication and cooperation between the AMS team and doctors, adjust the compensation system to facilitate better AMS implementation, and offer supportive measures that enable the adoption of strict regulations.</p>","PeriodicalId":12926,"journal":{"name":"Health policy and planning","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143668964","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

To respond, Mexico passed comprehensive legislation addressing VAW, which outlines the role of the health system in identifying, treating, and referring women experiencing violence; however, implementation of such regulations has been slow and far from successful. Using a conceptual framework of political commitment, we conducted a health policy analysis to evaluate how health policies addressing violence against women in Mexico have been implemented. The political commitment framework includes the dimensions of expressed, institutional, and budgetary commitment. We adopted a multi-methods qualitative case study approach combining document analysis with 25 stakeholder interviews with policymakers and health facility directors in Mexico City. The results show that Mexico exhibits limited expressed political commitment from the president, but some commitment exists among Ministry of Health officials. We document that the mixed findings on expressed commitment are mediated, in part, by internalized social and gender norms that normalize and tolerate violence, which are present in society writ large. We find that institutional commitment exists through policies and institutions. However, monitoring systems for policy implementation were not working as designed, and there was limited effort and capacity to implement these policies, reflecting structural barriers and norms within the health system that shape the treatment of violence survivors. Finally, we found a budgetary allocation for VAW; however, it was unclear if the budget was utilized correctly. While progress has been made in addressing VAW in the health system in Mexico, implementation is lagging due to a lack of political commitment, and thus, policies are likely not reaching their intended beneficiaries: survivors of violence.</p>","PeriodicalId":12926,"journal":{"name":"Health policy and planning","volume":" ","pages":""},"PeriodicalIF":2.9,"publicationDate":"2025-03-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143582290","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cost analysis from the provider perspective used data collected during the trial and from administrative records. Statistical differences were derived using t-tests. The mean cost per enrolled child under OptiMA was $123 [95% confidence interval (CI): 114-132], not statistically different from the standard group [$127 (95%CI: 118-136), P = 0.549], while treatment success (i.e. recovery to MUAC > 125 mm and no relapse for 6 months) under OptiMA was 9% higher (72 vs 63%, P = 0.004).

We used data from Ethiopian Demographic and Health Surveys conducted in 2000, 2005, 2011, and 2016. In each survey, around 15 500 women aged 15-49 years were interviewed from about 550 neighborhoods randomly sampled from across the country. Perinatal and pregnancy-related mortality were used as outcome variables. We carried out an optimized hotspot analysis using the Getis-Ord Gi* statistic in ArcGIS Pro to identify the time trend of geographical clusters with high (hot spot) and low (cold spot) perinatal and pregnancy-related mortality. In addition, we conducted a geographically weighted Poisson regression in R to examine the factors associated with the spatial distribution of perinatal and pregnancy-related mortality. Perinatal and pregnancy-related mortality exhibited a clustering pattern, indicating the presence of geographic inequality, with a decreasing pattern from 2000 to 2016. We detected hotspot areas in developed administrative regions of Amhara, Oromia, and Southern Nations, indicating inequality within large regions. Inequality in perinatal mortality was associated with rural residence, younger age of women, and high birth rate, whereas pregnancy-related mortality was associated with low autonomy, younger age, and anemia. We found that anemia (P-value = .01) has a geographically varying relationship with perinatal mortality, while education (P-value = .03) and wealth (P-value = 0.01) are associated with pregnancy-related mortality.
