Abstract: | BACKGROUND AND OBJECTIVES: Decisions about the dissemination of HIV interventions need to be informed by evidence of their cost-effectiveness in reducing negative health outcomes. Having previously shown the effectiveness of a single-session video-based group intervention (VOICES/VOCES) in reducing incidence of sexually transmitted diseases (STD) among male African American and Latino clients attending an urban STD clinic, this study estimates its cost-effectiveness in terms of disease averted. METHODS: Cost-effectiveness was calculated using data on effectiveness from a randomized clinical trial of the VOICES/VOCES intervention along with updated data on the costs of intervention from four replication sites. STD incidence and self-reported behavioral data were used to make estimates of reduction in HIV incidence among study participants. RESULTS: The average annual cost to provide the intervention to 10 000 STD clinic clients was estimated to be US$447 005, with a cost per client of US$43.30. This expenditure would result in an average of 27.69 HIV infections averted, with an average savings from averted medical costs of US$5 544 408. The number of quality adjusted life years saved averaged 387.61, with a cost per HIV infection averted of US$21 486. CONCLUSIONS: This brief behavioral intervention was found to be feasible and cost-saving when targeted to male STD clinic clients at high risk of contracting and transmitting infections, indicating that this strategy should be considered for inclusion in HIV prevention programming. |
