简要总结
The investigators implemented and evaluated a pilot program in Shinyanga Region, Tanzania to bring prevention of HIV services to communities using community health workers (CHWs). The intervention aimed to integrate community-based maternal and child health services with HIV prevention, treatment, and care-bridging the gap between women and facility, and enhancing the potential benefits of Option B+. Option B+ is the current World Health Organization recommendation for prevention of mother-to-child transmission, but its success in sub-Saharan Africa may be threatened by overburdened clinics and staff. Consequently, paraprofessionals like CHWs can be key partners in the delivery and/or enhancement of health services in the community.
The study focuses on whether this approach: increases retention in care; improves adherence to antiretrovirals (ARVs); or improves the number of women initiating antiretroviral therapy and the timing of initiation. Investigators hypothesize improvements along primary and secondary outcome indicators in the treatment group. This evaluation helps illuminate both the impact and feasibility of the intervention, and the role that CHWs may play in the elimination of mother-to-child transmission services.
