Abstract

Initiating antiretroviral therapy (ART) early in pregnancy is an important component of effective interventions to prevent the mother-to-child transmission of HIV (PMTCT). The rapid initiation of ART in pregnancy (RAP) program was a package of interventions to expedite ART initiation in pregnant women in Cape Town, South Africa. Retrospective cost-effectiveness, sensitivity and threshold analyses were conducted of the RAP program to determine the cost-utility thresholds for rapid initiation of ART in pregnancy. Costs were drawn from a detailed micro-costing of the program. The overall programmatic cost was US880 per woman and the base case cost-effectiveness ratio was US1,160 per quality-adjusted life year (QALY) saved. In threshold analyses, the RAP program remained cost-effective if mother-to-child transmission was reduced by ≥0.33 %; if ≥1.76 QALY were saved with each averted perinatal infection; or if RAP-related costs were under US4,020 per woman. The package of rapid initiation services was very cost-effective, as compared to standard services in this setting. Threshold analyses demonstrated that the intervention required minimal reductions in perinatal infections in order to be cost-effective. Interventions for the rapid initiation of ART in pregnancy hold considerable potential as a cost-effective use of limited resources for PMTCT in sub-Saharan Africa.
