title: Cost and cost-effectiveness of community-based care for tuberculosis in Cape Town, South Africa.
abstract: METHODS
  Guguletu and Nyanga areas of Cape Town, South Africa.
  
  
  OBJECTIVE
  To evaluate the affordability and cost-effectiveness of community involvement in tuberculosis (TB) care.
  
  
  METHODS
  A cost-effectiveness analysis comparing treatment for new smear-positive pulmonary and retreatment TB patients in two similar townships, one providing clinic-based-care with community-based observation options available for its TB patients (Guguletu) and one providing clinic-based care only, with no community-based observation of treatment (Nyanga). Costs were assessed from a societal perspective in 1997 US dollars, and cost-effectiveness was calculated as the cost per patient successfully treated.
  
  
  RESULTS
  TB treatment in Guguletu was more cost-effective than TB treatment in Nyanga for both new and retreatment patients (dollars 726 vs. dollars 1201 and dollars 1419 vs. dollars 2058, respectively). This reflected both lower costs (dollars 495 vs. dollars 769 per patient treated for new cases; dollars 823 vs. dollars 1070 per patient treated for retreatment cases) and better treatment outcomes (successful treatment rate 68% vs. 64% and 58% vs. 52% for new and retreatment patients, respectively). Within Guguletu, community-based care was more than twice as cost-effective as clinic-based care (dollars 392 vs. dollars 1302 per patient successfully treated for new patients, and dollars 766 vs. dollars 2008 for retreatment patients), for similar reasons (e.g., for new cases, dollars 314 vs. dollars 703 per patient treated, successful treatment rate 80% vs. 54%).
  
  
  CONCLUSIONS
  Community involvement in TB care can improve the affordability and cost-effectiveness of TB treatment in urban South Africa. Expansion in the Western Cape and in similar areas of the country is worthy of serious consideration by planners and policy-makers.
