Community Health Worker Programs

Introduction​

Community Health Workers (CHWs) are frontline public health workers who are trusted members of the communities they serve. They bridge the gap between health systems and communities, particularly in settings where access to formal healthcare is limited. CHWs play a crucial role in disease prevention, health promotion, and connecting people to needed services.

This document explores the principles, models, and implementation approaches for effective CHW programs. Drawing from decades of global experience, it provides frameworks for designing, implementing, and sustaining CHW initiatives that can significantly improve health outcomes while empowering communities and strengthening health systems.

Understanding Community Health Workers​

Definition and Roles​

CHWs are known by many names globally (health promoters, village health workers, community health volunteers, etc.) but share key characteristics:

  • Community Members: Selected from and by the communities they serve
  • Trusted Intermediaries: Bridge between formal health systems and communities
  • Limited Formal Training: Trained in basic health promotion and disease prevention
  • Focus on Accessibility: Bring services closer to where people live and work
  • Cultural Competence: Understand local language, customs, and beliefs
  • Advocacy Role: Represent community health needs to the health system

Core Functions​

CHWs typically perform a range of functions that vary based on context:

  • Health Education: Providing information on disease prevention and healthy behaviors
  • Basic Healthcare: Delivering simple treatments and first aid
  • Referral and Linkage: Connecting community members to health facilities
  • Case Finding: Identifying individuals needing services
  • Data Collection: Gathering basic health information
  • Social Support: Providing emotional and practical assistance
  • Community Mobilization: Organizing collective action for health

Historical Context​

CHW programs have evolved over decades of implementation:

  • 1960s-1970s: Emergence of "barefoot doctors" in China and similar programs
  • 1978: Alma-Ata Declaration highlighting CHWs as part of primary healthcare
  • 1980s-1990s: Mixed results leading to decline in some programs
  • 2000s: Renewed interest with focus on HIV, TB, and maternal-child health
  • 2010s: Growing evidence base and integration into health systems
  • Present: Recognition as essential workforce for universal health coverage
