Factors Associated with PMTCT Cascade Completion in Four African Countries

Dionne-Odom, J., Welty, T.K., Westfall, A.O., et al.

Many countries are working to reduce or eliminate mother-to-child transmission (MTCT) of HIV. Prevention efforts have been conceptualized as steps in a cascade but cascade completion rates during and after pregnancy are low.

A cross-sectional survey was performed across 26 communities in Cameroon, Cote d’Ivoire, South Africa, and Zambia. Women who reported a pregnancy within two years were enrolled. Participant responses were used to construct the PMTCT cascade with all of the following steps required for completion: at least one antenatal visit, HIV testing performed, HIV testing result received, initiation of maternal prophylaxis, and initiation of infant prophylaxis. Factors associated with cascade completion were identified using multivariable logistic regression modeling.

Of 976 HIV-infected women, only 355 (36.4%) completed the PMTCT cascade. Although most women (69.2%) did not know their partner’s HIV status; awareness of partner HIV status was associated with cascade completion (aOR 1.4, 95% CI 1.01–2.0). Completion was also associated with receiving an HIV diagnosis prior to pregnancy compared with HIV diagnosis during or after pregnancy (aOR 14.1, 95% CI 5.2–38.6). 

The study concluded that pregnant women with HIV infection in Africa who were aware of their partner’s HIV status and who were diagnosed with HIV before pregnancy were more likely to complete the PMTCT cascade.

In 2013, Uganda updated its prevention of maternal-to-child transmission of HIV program to Option B+, which requires that all HIV-infected pregnant and breastfeeding women be started on lifelong antiretroviral therapy (ART) regardless of CD4 count…

To understand the uptake of HIV services by adolescent women, the authors conducted a retrospective analysis of patient-level data (2011–2013) on services for antenatal care (ANC) and prevention of mother-to-child transmission (PMTCT) in 36 facilities in 5 districts in Zimbabwe.

An essential first step in caring for HIV-infected children is accurate and early diagnosis of HIV, early HIV testing, prompt return of results, and rapid initiation of treatment.

This study aimed to evaluate the impact of clinic-based prevention of mother-to-child transmission (PMTCT) community support by trained lay health workers in addition to standard clinical care on PMTCT infant outcomes.

Option B+ for prevention of mother-to-child transmission (PMTCT) specifies treating all HIV-positive women with antiretroviral therapy (ART) regardless of CD4 count. This simplified approach enhances countries' capacity to reach national HIV targets and contribute to the global 90-90-90 goals.…
