Guidance for Triangulating Data and Estimates of HIV Prevalence Among Pregnant Women and Coverage of PMTCT Using the Spectrum AIDS Impact Module.

ABSTRACT:

Background

Most countries use the Spectrum AIDS Impact Module (Spectrum-AIM), antenatal care routine HIV testing, and antiretroviral treatment data to estimate HIV prevalence among pregnant women. Nonrepresentative program data may lead to inaccurate estimates of HIV prevalence and treatment coverage for pregnant women.

Setting

One hundred fifty-four countries and subnational locations across 126 countries.

Methods

Using 2023 UNAIDS HIV estimates, we calculated 3 ratios: (1) HIV prevalence among pregnant women to all women 15-49 yrs (prevalence), (2) ART coverage before pregnancy to women 15-49 yrs ART coverage (ART prepregnancy), and (3) ART coverage at delivery to women 15-49 yrs ART coverage (PMTCT coverage). We developed an algorithm to identify and adjust inconsi
