Goal of analysis Estimate the cost, health effects, and cost-effectiveness of a diarrhea, malaria and HIV IPC as implemented in Lurambi district, Western Kenya, September 2008.
Methods: Sources Program costs: Empirical for campaign as implemented, plus modeled “Scaled-Up Replication” (SUR) Health effects (deaths and DALYs averted): Published trials and meta-analyses, and disease incidence modeling Costs of medical care incurred/averted: Published studies and databases
Results: Program Costs As implemented: $42 SUR: $32
Results: Health Effects Diarrhea (Filters) Malaria (LLIN) HIV (VCT, condoms)TOTAL Deaths averted DALYs averted (prevention) DALYs averted(earlier HIV care) TOTAL DALYs Deaths and DALYs averted by intervention component:
Results: Costs Diarrhea (Filters) Malaria (LLIN) HIV (VCT, condoms)TOTAL Prevention $48,123$10,420$25,569 $85,113 Effect on use of ART -- ($37,097) Total $48,123$10,420($10,538) $48,015 Costs averted/(added) by intervention component:
Results: Cost-effectiveness
Conclusion A mass, rapidly implemented IPC for HIV, malaria and diarrhea in a Western Kenya setting provides substantial health benefits in terms of deaths and DALYs averted The campaign also appears economically attractive (cost-saving).
