A cost-utility study on HIV/AIDS 'one-stop service' pilot at county level / 中华预防医学杂志

ABSTRACT

<p><b>OBJECTIVE</b>To conduct a cost utility study on the HIV/AIDS 'one-stop service' at county level.</p><p><b>METHODS</b>Financial records and questionnaires were used to collect the information about the resource allocation and the effectiveness of antivirus treatment (ART) during the two period which were January 2012-June 2013 and July 2013-December 2013 in the three pilot counties providing 'one-stop service'. Treeage Pro 2009 was used to build the Markov model to simulate the evolution of 5 different HIV statuses, including HIV infection, AIDS, HIV infection receiving ART, AIDS receiving ART and death. And compared the cost-utility ratios between current ART process and 'one-stop service' process. National and local epidemic data and literature review were used to provide the parameters in the model, including prior probabilities of each status, transferring probabilities among each status, health utility values and investments of each status and discount rate.</p><p><b>RESULTS</b>The expenditures related with 'one-stop service' in the three counties were 2 627 339, 209 969, and 191 658 RMB, respectively between July and December, 2013. The average periods from HIV infection confirmation to ART initiation was reduced from 8 weeks to 18, 10 and 16 days, respectively. The percentage of receiving ART within 30 d among those qualified were increased from 46.7% (63/135) to 64.3% (45/70) in county A, from 40.0% (16/40) to 69.4% (25/36) in county B, and from 9.5% (4/42) to 50.0% (19/38) in county C. If current process was applied, the CUR in three counties would be 10 391.89 RMB/quality adjusted life years (QALY), 6 271.42 RMB/QALY and 3 515.94 RMB/QALY, and these would be 10 825.08 RMB/QALY, 8 522.30 RMB/QALY and 10 414.65 RMB/QALY with application of 'one-stop service'.</p><p><b>CONCLUSION</b>'one-stop service' could decrease the interval between HIV infection confirmation and ART initiation and increase the percentage of receiving ART among people living with HIV(PLHIV), more QALYs would be obtained with more resources invested.</p>
