However, premiums may be unaffordable for the poorest households. The Innovative Partnership for Universal Sustainable Healthcare (i-PUSH) program targets low-income women and their households to improve their access to and utilization of quality healthcare, including RMNCH services, by providing subsidized, mobile phone-based NHIF coverage in combination with enhanced, digital training of community health volunteers (CHVs) and upgrading of health facilities. This study evaluated whether expanded NHIF coverage increased the accessibility and utilization of quality basic RMNCH services in areas where i-PUSH was implemented using a longitudinal cluster randomized controlled trial in Kakamega, Kenya. A total of 24 pair-matched villages were randomly assigned either to the treatment or the control group. Within each village, 10 eligible households (i.e., with a woman aged 15-49 years who was either pregnant or with a child below 4 years) were randomly selected. The study applied a Difference-in-Difference methodology based on a pooled cross-sectional analysis of baseline, midline and endline data, with robustness checks based on balanced panels and ANCOVA methods. The analysis sample included 346 women, of whom 248 had had a live birth in the 3 years prior to any of the surveys, and 424 children aged 0-59 months. Improved NHIF coverage did not have a statistically significant impact on any of the RMNCH outcome indicators at midline nor endline. Uptake of RMNCH services, however, improved substantially in both control and treatment areas at endline compared to baseline. For instance, significant increases were observed in the number of antenatal care visits from baseline to midline (mean = 2.62 to 2.92) p < 0.01) and delivery with a skilled birth attendant from baseline to midline (mean = 0.91 to 0.97 (p < 0.01). Expanded NHIF coverage, providing enhanced access to RMNCH services of unlimited duration at both public and private facilities, did not result in an increased uptake of care, in a context where access to basic public RMNCH services was already widespread. However, the positive overall trend in RMNCH utilization indicators, in a period of constrained access due to the COVID-19 pandemic, suggests that the other components of the i-PUSH program may have been beneficial. Further research is needed to better understand how the provision of insurance, enhanced CHV training and improved healthcare quality interact to ensure pregnant women and young children can make full use of the continuum of care.</p>","PeriodicalId":12926,"journal":{"name":"Health policy and planning","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142055413","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}

However, recent studies have shown that health financing schemes like the BHCPF in Nigeria are suboptimal and have frequently attributed this to weak accountability and governance of the schemes. However, little is known about accountability and governance of health financing in Nigeria, particularly from the perspective of key actors within the system. This study explores perceptions around governance and accountability through qualitative, in-depth interviews with key BHCPF actors including high-level government officers, academics and Civil Society Organisations. Thematic analysis of the findings reveals broad views among respondents that financial processes are appropriately ring-fenced, and that financial mismanagement is not the most pressing accountability gap. Importantly, respondents report that accountability processes are unclear and weak in subnational service delivery, and cite low utilisation, implicit priority-setting, and poor quality as issues.

Multiple diseases are sensitive to climate change, including cardiovascular diseases (CVDs), which are also the leading cause of death globally. Countries such as India face a compounded challenge, with a growing burden of CVDs and a high vulnerability to climate change, requiring a co-ordinated, multi-sectoral response. In this framework synthesis, we analysed whether and how CVDs are addressed with respect to climate change in the Indian policy space. We identified 10 relevant national-level policies, which were analysed using the framework method. Our analytical framework consisted of four themes: (i) political commitment; (ii) health information systems; (iii) capacity building; and (iv) cross-sectoral actions. Additionally, we analysed a subset of these policies and 29 state-level climate change and health action plans using content analysis to identify health priorities. Our analyses revealed a political commitment in addressing the health impacts of climate change; however, CVDs were poorly contextualized with most of the efforts focusing on vector-borne and other communicable diseases, despite their recognized burden. Heat-related illnesses and cardiopulmonary diseases were also focused on but failed to encompass the most climate-sensitive aspects. CVDs are insufficiently addressed in the existing surveillance systems, despite being mentioned in several policies and interventions, including emergency preparedness in hospitals and cross-sectoral actions. CVDs are mentioned as a separate section in only a small number of state-level plans, several of which need an impetus to complete and include CVD-specific sections. We also found several climate-health policies for specific diseases, albeit not for CVDs.

Results-based financing and socioeconomic-related inequalities in maternal health outcomes in Zimbabwe.","authors":"Marshall Makate, Nyasha Mahonye","doi":"10.1093/heapol/czae080","DOIUrl":"https://doi.org/10.1093/heapol/czae080","url":null,"abstract":"<p><p>The results-based financing (RBF) program, first implemented in Zimbabwe in 2011 and gradually expanded to other districts, aimed to address disparities in maternal health outcomes by improving the utilisation of health services. This study leverages the staggered rollout of the program as a quasi-experimental design to assess its impact on asset wealth-related inequalities in selected maternal health outcomes. The objective is to determine whether RBF can effectively reduce these disparities and promote equitable healthcare access. We employ an extended two-way fixed effects (ETWFE) model to exploit temporal variation in RBF implementation as well as individual-level variation in birth timing for identification. Utilising pooled cross-sectional and nationally representative data from the Zimbabwe demographic and health surveys collected between 1999 and 2015, our analysis reveals significant reductions in relative and absolute maternal health inequalities, especially in the frequency and timing of prenatal care, delivery by caesarean section, and family planning. Specifically, the RBF program is associated with reductions in disparities for completing at least four or more prenatal care visits (-0.026, p < 0.01), first-trimester prenatal care (-0.033, p < 0.01), delivery by caesarean section (-0.028, p < 0.005), and family planning (-0.033, p < 0.005). Additionally, the program is associated with improved prenatal care quality, as evidenced by progress on the prenatal care quality index (-0.040, p < 0.01). These effects are more pronounced among lower socioeconomic groups in RBF districts, highlighting RBF's potential to promote equitable healthcare access. Our findings advocate for targeted policy interventions prioritising expanding access to critical maternal health services in underserved areas and incorporating equity-focused measures within RBF frameworks to ensure inclusive and effective healthcare delivery in Zimbabwe and other low-income countries.</p>","PeriodicalId":12926,"journal":{"name":"Health policy and planning","volume":null,"pages":null},"PeriodicalIF":2.9,"publicationDate":"2024-08-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142055409","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}

It can be used to identify and address gender disparities in program participation, outcomes, and benefits, as well as ensure that programs are designed and implemented in a way that is inclusive and accessible for all. While gender-responsive M&E is most effective when interventions and programs intentionally integrate a gender lens, it is relevant for all health systems programs and interventions. Within the literature, gender-responsive M&E is defined in different and diverse ways, making it difficult to operationalize. This is compounded by the complexity and multi-faceted nature of gender. Within this methodological musing, we present our evolving approach to gender-responsive M&E which we are operationalizing within the Monitoring for Gender and Equity (MAGE) project. We define gender-responsive M&E as intentionally integrating the needs, rights, preferences, and power relations among women and girls, men and boys, and gender minority individuals, as well as across social, political, economic, and health systems, in M&E processes. This is done through the integration of different types of gender data and indicators, including: sex or gender specific, sex or gender disaggregated, sex or gender specific/disaggregated which incorporate needs, rights and preferences, and gender power relations and systems indicators. Examples of each of these are included within the paper. Active approaches can also enhance the gender-responsiveness of any M&E activities, including incorporating an intersectional lens and tailoring the types of data and indicators included and processes used to the specific context. Incorporating gender into the programmatic cycle, including M&E, can lead to more fit-for-purpose, effective, and equitable programs and interventions.

This study aims to provide evidence about the potential effects of taxation to reduce the burden of tobacco-related diseases and the main attributable social costs in Mexico, including informal (unpaid) care costs, which are frequently ignored. We employ a first-order Monte Carlo microsimulation model that follows hypothetical population cohorts considering the risks of an adverse health event and death. First, we estimate tobacco-attributable morbidity and mortality, direct medical costs, and indirect costs, such as labour productivity losses and informal care costs. Then, we assess the potential effects of a 50% cigarette price increase through taxation and two alternative scenarios of 25% and 75%. The inputs come from several sources, including national surveys and vital statistics. Each year, 63,000 premature deaths and 427,000 disease events are attributable to tobacco in Mexico, while social costs amount to MX$194.6 billion (US$8.5) -MX$116.2 (US$5.1) direct medical costs and MX$78.5 (US$3.4) indirect costs-, representing 0.8% of GDP. Current tobacco tax revenue barely covers 23.3% of these costs. Increasing cigarette prices through taxation by 50% could reduce premature deaths by 49,000 over the next decade, while direct and indirect costs averted would amount to MX$87.9 billion (US$3.8) and MX$67.6 billion (US$2.9), respectively.

In-depth interviews were conducted with 11 key informants. The interview tool guide was informed by a review of published and grey literature and government websites. The interviews were recorded as both audio and video and transcribed. A thematic coding framework was developed for the analysis.

The themes identified were as follows: the status of cost accounting in the Indian hospital sector, legal and regulatory requirements for cost reporting, challenges to implementing cost accounting and recommendations for improving cost reporting by health care providers. The findings indicate that the sector lacks maturity in cost accounting due to a lack of understanding of its benefits, limited capacity and weak enforcement of cost reporting regulations. Providers recognize the value of cost analysis for investment decisions but have mixed opinions on the willingness to gather and report cost information, citing resource constraints and a lack of trust in payers. Additionally, heterogeneity among providers will require tailored approaches in developing cost accounting reporting frameworks and regulations.

Context is central to the policy cycle, yet the influence of crises on policy formulation is underrepresented in the health policy literature in low- and middle-income countries (LMICs). This paper analyses a detailed case study of how the COVID-19 crisis influenced policy formulation processes for the regulation of alcohol in South Africa, as part of COVID-19 control measures, in 2020 and 2021. It provides a picture of the policy context, specifically considering the extent to which the crisis influenced the position and power of actors, and policy content. Qualitative data were collected from nine key informant interviews and 127 documents. Data were analysed using thematic content analysis. A policy formulation conceptual framework was applied as a lens to describe complex policy formulation processes. The study revealed that the perceived urgency of the pandemic prompted a heightened sense of awareness of alcohol-related trauma as a known, preventable threat to public health system capacity. This enabled a high degree of innovation among decision-makers in the generation of alternative alcohol policy content. Within the context of uncertainty, epistemic and experiential policy learning drove rapid, adaptive cycles of policy formulation, demonstrating the importance of historical and emerging public health evidence in crisis-driven decision-making. Within the context of centralization and limited opportunities for stakeholder participation, non-state actors mobilized to influence policy through the public arena. The paper concludes that crisis-driven policy formulation processes are shaped by abrupt redistributions of power among policy actors and the dynamic interplay of evolving economic, political and public health priorities.
