HIV/AIDS and TB: contextual issues and policy choice in programme relationships.

Tuberculosis (TB) and HIV/AIDS affect each other closely. Given the rapid spread of the HIV-driven TB epidemic worldwide, the case for establishing some form of relationship between control activities for HIV/AIDS and TB is clear. However, the question 'how' has not been resolved satisfactorily. TB and HIV/AIDS programmes have traditionally maintained their own management, supervision, funding flows and specialist boundaries. This article explores opportunities and challenges for collaboration between the two, through drawing on the expertise in organization and management, policy analysis and disease control of both TB and HIV/AIDS. Based on an extensive literature review, the article investigates how contextual issues affect the design of a collaboration; what the organizational options are; and what impact a collaboration would have. A universal model for organizational change is unlikely and changes may present as both solutions and contradictions. Careful planning and consultation are required before implementing the changes, in order to avoid jeopardizing the function and effectiveness of both disease control programmes and the health service system.
