Lay health workers and HIV programmes: implications for health systems

Area of Science:

• Public Health
• Health Systems Research
• Sociology of Health

Background:

• Significant investment in antiretroviral access and AIDS programs has resulted in a large influx of lay workers into health systems in developing nations.
• In South Africa, an estimated 65,000 lay health workers, primarily involved in HIV/TB care, now outnumber professional nurses and primary healthcare providers in the public sector.
• This phenomenon has evolved organically, with lay workers assuming diverse care-giving, support, and advocacy roles.

Purpose of the Study:

• To examine the diverse forms, traditions, and orientations of lay health work in South Africa.
• To analyze the system-wide effects of a substantial lay health worker presence within public health systems.
• To explore the implications of regularizing and formalizing the status of lay health workers and their role as intermediaries between the state and citizens.

Main Methods:

• Case study analysis focusing on South Africa.
• Discussion of the organic growth and varied roles of lay health workers.
• Exploration of the system-wide effects and emerging policy questions regarding lay health worker integration.

Main Results:

• Lay health work has emerged organically, fulfilling numerous care, support, and advocacy functions.
• The presence of lay health workers significantly impacts health systems, creating an intermediary layer between the state and citizens.
• Growing pressure exists to formalize the status and roles of these workers within the health system.

Conclusions:

• The significant presence of lay health workers, particularly in HIV/AIDS-affected regions, necessitates a deeper understanding of their diverse roles and integration.
• Further research is crucial to characterize different types of lay involvement in health systems, especially in the context of antiretroviral therapy.
• The re-emergence of lay health work represents a critical evolution in health systems, requiring a broader perspective on its meaning and implications.
