Objective: To evaluate the cost effectiveness of HIV testing strategy in hospitals from 2006 to 2010 in Guangzhou.
Methods: According to the HIV test strategy costs and the number of HIV patients found in Guangzhou, following aspects were calculated as the total cost of HIV testing strategy in hospitals from 2006 to 2010 of Guangzhou, the cost of finding each HIV patient, and the cost of obtaining one quality adjusted life year (QALY) using Markov model.
Results: The total HIV test strategy costs increased from 11 106.98 thousand Yuan to 25 105.58 thousand Yuan, and 4599 HIV positive patients were found due to this strategy. The cost-effectiveness of HIV testing were different in hospitals from 2006 to 2010 in Guangzhou. The lowest cost-effectiveness ratio of HIV testing strategy was 11 810 Yuan per HIV positive patient, the highest was 23 510 Yuan, and the average was 16 070 Yuan. According to the Markov model result, 7.2855 QALYs could be gained per HIV patient on average via HIV testing strategy in 113 hospitals in Guangzhou, and the cost of obtaining one QALY was 2210 Yuan.
Conclusion: The cost effectiveness ratio of HIV testing strategy in hospitals in Guangzhou was significantly lower than the standard of WHO recommended, and it was cost-effective to carry out the HIV testing strategy in Guangzhou.
