About this study

Official title: Short-term Effectiveness of a Community Health Worker Intervention for HIV-infected Pregnant Women in Tanzania to Improve Treatment Adherence and Retention in Care: A Cluster-Randomized Trial

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.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Community Health Worker interventionBehavioural

    The intervention included four integrated components: 1) formal linkage of CHWs to health facilities; 2) CHW-led antiretroviral therapy (ART) adherence counseling; 3) loss to follow-up tracing by CHWs; and 4) distribution of Action Birth Cards (ABCs), a birth planning tool.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Retention in HIV care

    Binary variable taking the value of 1 if the women has had at least one clinic visit in the postpartum period (60-120 days after birth), and zero otherwise.

    Measured: 120 days postpartum

Secondary outcomes (3)
  1. Adherence to ARVs

    ART adherence will be measured through a binary variable taking the value of 1 when adherence is at least 95%, and the value of zero otherwise. We measure adherence using the medication possession ratio (MPR), computed as the number of days ARVs are prescribed or dispensed divided by the number of days in the interval. It has been shown to be associated with short-term virologic outcomes.

    Measured: Birth to 90 days postpartum

  2. Timing of ART initiation

    Defined by gestational week at start of ART, which was computed using standard approaches (i.e., 40 weeks prior to the date of birth or, when available, the expected delivery date based on last menstrual period).

    Measured: ART initiation date, expressed as gestational week of pregnancy, up to 40 weeks

  3. Initiation of ART

    Measured as the number of HIV-infected women in the sample who had any evidence of beginning ART after pregnancy, among women without evidence of treatment prior to pregnancy (women who had initiated ART before the current pregnancy were excluded).

    Measured: Through pregnancy and up to 90 days after birth
