OBJECTIVETo perform cost-effectiveness analysis of interventions in female sex workers in Dehong prefecture in China, with an aim of providing evidence for rational resource allocation in female sex worker interventions in the future.

METHODSThe data of expenses for female sex worker interventions in Dehong from 2005 - 2007 were obtained through questionnaire survey. Meanwhile, the data from baseline survey in 2004, from surveillance of female sex workers from 2005 through 2007 as well as from the special survey on sexual transmission in 2007 were collected. Intervention effectiveness was estimated by using SEX 2.0 Tool recommended by UNAIDS. The cost-effectiveness ratio is calculated as the total cost divided by the number of estimated non-HIV patients due to these interventions.

RESULTSThe total cost for female sex worker interventions is 916 400 RMB from 2005 through 2007, and a total of 3297 female sex workers were effectively intervened in these three years. Thus, the actual intervention cost for each female sex worker (unit cost) is 277.9 RMB. If all the intervention work is performed as required, the predicted unit cost for female sex worker intervention would be 500.5 RMB. During the period of 2005 through 2007, 69 female sex workers had been successfully prevented from HIV infection; therefore, the cost-effectiveness ratio is 13 282 RMB.

CONCLUSIONIntervention among female sex workers is highly cost-effective.
