Primary health care reforms: a scoping review.

BACKGROUND: Demographic transitions, societal changes, and evolving population health needs are placing increasing pressure on healthcare systems, necessitating ongoing reforms. Primary health care (PHC) is a foundational component of Universal Health Coverage (UHC) and sustainable health systems. Many countries have undertaken PHC reforms aimed at improving population health. This review explores the objectives, implementation mechanisms, challenges, and outcomes of these reforms.

METHODS: We conducted a systematic review of studies sourced from five databases (PubMed, Scopus, Proquest, Embase, and Science Direct), applying the World Health Organization's Health Systems Framework for deductive content analysis. The PRISMA guidelines were followed to ensure transparency and rigour in summarizing the published literature.

RESULTS: A total of 147 types of interventions were identified, with most targeting service delivery and financing. Key reform objectives included expanding access to care, improving financing and payment systems, scaling up family physician programmes, increasing government health expenditure, leveraging private sector capacities, and strengthening the PHC workforce. These interventions resulted in expanded public health coverage, enhanced access to PHC, increased utilization of services among low-income populations, broader social insurance coverage, and improved service quality, contributing to better community health outcomes.

CONCLUSION: The success of PHC reforms depends on their alignment with political, social, and cultural contexts, as well as consideration of the social determinants of health. Strong governmental support, managerial stability, decentralization, and regional capacity building are essential for sustainable implementation. Reforms should be gradual, supported by accurate forecasting, adequate and sustainable resources, and evidence-based strategies, drawing on international experiences.
