Preferences of Pregnant and Postpartum Women for Differentiated Service Delivery in Kenya

Abstract

Background: Differentiated service delivery models are implemented by HIV care programs globally, but models for pregnant and postpartum women living with HIV (PPWH) are lacking. We conducted a discrete choice experiment to determine women's preferences for differentiated service delivery. Setting: Five public health facilities in western Kenya. Methods: PPWH were enrolled from April to December 2022 and asked to choose between pairs of hypothetical clinics that differed across 5 attributes: clinic visit frequency during pregnancy (monthly vs. every 2 months), postpartum visit frequency (monthly vs. only with routine infant immunizations), seeing a mentor mother (each visit vs. as needed), seeing a clinician (each visit vs. as needed), and basic consultation cost (0, 50, or 100 Kenya Shillings [KSh]). We used multinomial logit modeling to determine the relative effects (β) of each attribute on clinic choice. Results: Among 250 PPWH (median age 31 years, 42% pregnant, 58% postpartum, 20% with a gap in care), preferences were for pregnancy visits every 2 months (β = 0.15), postpartum visits with infant immunizations (β = 0.36), seeing a mentor mother and clinician each visit (β = 0.05 and 0.08, respectively), and 0 KSh cost (β = 0.39). Preferences were similar when stratified by age, pregnancy, and retention status. At the same cost, predicted market choice for a clinic model with fewer pregnant/postpartum visits was 75% versus 25% for the standard of care (ie, monthly visits during pregnancy/postpartum). Conclusion: PPWH prefer fewer clinic visits than currently provided within the standard of care in Kenya, supporting the need for implementation of differentiated service delivery for this population.

Understanding Women’s Preferences for Prevention of Mother-to-Child HIV Transmission Services in Kenya

“…From April to December 2022, we conducted a discrete choice experiment to understand women’s relative preferences for differentiated HIV services in western Kenya. [ 15 ] In this region, the HIV prevalence is ∼5% among women of reproductive age (15–49 years). [ 16 ] PMTCT services including ART dispensing are provided in integrated ANC and postnatal clinics (PNC) rather than HIV clinics.…”
