Institutional Dynamics of Health System Strengthening in Low- and Middle-Income Countries: A Review of Governance Mechanisms and Reform Challenges

This study examines the role of institutional governance in strengthening health systems in low- and middle-income countries (LMICs). The systematic review synthesizes findings from 75 studies to explore key themes such as leadership and institutional capacity, decentralisation, accountability mechanisms, financing and resource allocation, and digital governance. The study employs the institutional theory as a framework for analysis. The analysis reveals that strong leadership and institutional capacity are essential for navigating the complex institutional environments in LMICs, but path dependence and institutional inertia often hinder effective reform. Decentralisation efforts were found to be unsuccessful when local governance structures lacked the necessary resources and institutional capacity to implement reforms, leading to mimetic isomorphism, where decentralised models were adopted without adaptation to local contexts. Similarly, accountability mechanisms, including performance-based financing and regulatory frameworks, were often undermined by institutional weaknesses such as corruption and political interference. Financing and resource allocation were influenced by institutional factors, where historical patterns of centralized control limited the adoption of innovative financing models. Digital health technologies, although promising, were frequently hampered by insufficient infrastructure and political resistance to change. The study argues that successful health system strengthening in LMICs requires institutional adaptation and institutional work to overcome barriers such as political will, resource constraints, and institutional resistance. The findings contribute to the theoretical understanding of health governance in LMICs and provide practical insights for policymakers aiming to implement sustainable reforms. Future research should explore how institutional frameworks can be adapted to support resilient health systems in LMICs.
