Calculating the Number of Pregnant Women Receiving Standardized Services for PMTCT of HIV in Liangshan Prefecture, Based on the Equivalent Method.

ABSTRACT

OBJECTIVE: To calculate the number of pregnant women who receive standardized prevention of mother-to-child transmission (PMTCT) services for HIV annually. METHODS: HIV-positive pregnant women in six counties of Liangshan Prefecture in 2017 were selected as study subjects. The entire process, from when the subjects first received the PMTCT of HIV services to the end, was divided into four stages, which were further divided into 25 phases. The equivalent coefficient was used to indicate the weight of workload in each phase. Seven experts were invited to score the equivalent coefficient; the number of pregnant women who received standardized services to prevent the transmission of HIV was calculated. RESULTS: A total of 663 HIV-positive pregnant women were registered in six Liangshan Prefecture counties in 2017. This figure was converted into 7,780 person-months devoted to HIV-positive pregnant women, with 260 person-months (3.34%) spent on the first antenatal care, 1,510 person-months (19.41%) during pregnancy, 378 person-months (4.86%) on delivery, and 5,632 person-months (72.39%) on post-partum period. The equivalent coefficient calculation showed that 314 HIV-positive pregnant women received standardized PMTCT services. CONCLUSION: The number of pregnant women receiving standardized services for the PMTCT of HIV can be calculated accurately using the equivalent method to identify the gap between the level of PMTCT of HIV intervention services needed and the actual workload.
