How do we determine whether community health workers are cost-effective? Some core methodological issues

Area of Science:

• Global Health
• Health Economics
• Public Health Policy

Background:

• Primary health care (PHC) programs utilizing community health workers (CHWs) are widespread in developing countries, aiming for "Health for All."
• CHW programs are intended to enhance healthcare cost-effectiveness by delivering essential services to underserved populations affordably.
• A significant gap exists in empirical data and robust economic evaluations confirming the cost-effectiveness of CHW programs.

Purpose of the Study:

• To investigate and propose extensions to economic evaluation methodologies.
• To better capture the institutional characteristics inherent in CHW programs.
• To provide evidence on the cost-effectiveness of CHWs in developing countries.

Main Methods:

• Review of existing economic evaluation frameworks for health interventions.
• Exploration of adaptations needed for conventional cost-effectiveness analysis.
• Consideration of institutional factors unique to CHW program implementation.

Main Results:

• Conventional economic evaluations may not adequately represent the complexities of CHW programs.
• Methodological extensions are necessary to accurately assess CHW cost-effectiveness.
• Further research is needed to develop and apply these extended methods.

Conclusions:

• Existing economic evaluation methods require adaptation to accurately assess CHW programs.
• Improved methodologies are crucial for evidence-based policy decisions regarding CHWs.
• This work highlights the need for refined economic analysis in global health initiatives.
