Increasing Access and Adherence to the PMTCT Cascade: Is There a Role for Economic Strengthening Interventions?

Interventions aimed at prevention of mother-to-child transmission (PMTCT) of HIV are extremely effective but remain underutilized in many countries. Common economic barriers to PMTCT experienced by pregnant women with HIV are well documented. Addressing these economic barriers has a potential to improve PMTCT utilization and further reduce mother-to-child HIV transmission. This review examines the evidence of the effects economic strengthening (ES) interventions have on use of and adherence to PMTCT and other health services relevant to PMTCT cascade. While very few studies on ES interventions were conducted in PMTCT settings, the results of a recent randomised trial demonstrate that conditional cash transfers offered to women in PMTCT programme can significantly improve retention in care and adherence to treatment. This review also considers evidence on ES interventions conducted within other health care settings relevant to PMTCT cascade. While the evidence from other settings is promising, it may not be fully applicable to PMTCT and more quality research on ES interventions among population of pregnant women with HIV is needed. Answering some of the research questions formulated by this review can provide more evidence for programme implementers and guide decisions about how to increase women’s use of and adherence to PMTCT services.
