title: Integrating tuberculosis and HIV services for people living with HIV: costs of the Zambian ProTEST Initiative.
abstract: BACKGROUND
  In the face of the dual TB/HIV epidemic, the ProTEST Initiative was one of the first to demonstrate the feasibility of providing collaborative TB/HIV care for people living with HIV (PLWH) in poor settings. The ProTEST Initiative facilitated collaboration between service providers. Voluntary counselling and testing (VCT) acted as the entry point for services including TB screening and preventive therapy, clinical treatment for HIV-related disease, and home-based care (HBC), and a hospice. This paper estimates the costs of the ProTEST Initiative in two sites in urban Zambia, prior to the introduction of anti-retroviral therapy.
  
  
  METHODS
  Annual financial and economic providers costs and output measures were collected in 2000-2001. Estimates are made of total costs for each component and average costs per: person reached by ProTEST; VCT pre-test counselled, tested and completed; isoniazid preventive therapy started and completed; clinic visit; HBC patient; and hospice admission and bednight.
  
  
  RESULTS
  Annual core ProTEST costs were (in 2007 US dollars) $84,213 in Chawama and $31,053 in Matero. The cost of coordination was 4%-5% of total site costs ($1-$6 per person reached). The largest cost component in Chawama was voluntary counselling and testing (56%) and the clinic in Matero (50%), where VCT clients had higher HIV-prevalences and more advanced HIV. Average costs were lower for all components in the larger site. The cost per HBC patient was $149, and per hospice bednight was $24.
  
  
  CONCLUSIONS
  This study shows that coordinating an integrated and comprehensive package of services for PLWH is relatively inexpensive. The lessons learnt in this study are still applicable today in the era of ART, as these services must still be provided as part of the continuum of care for people living with HIV.
