Site factors may be more important than participant factors in explaining HIV test acceptance in the prevention of mother-to-child HIV transmission programme in Kenya, 2005.

ABSTRACT

OBJECTIVE: To determine the role of participant factors on the acceptance of a Prevention-of-Mother-to-Child (PMTCT) HIV test programme in a situation with an opt-out testing strategy. METHODS: We analysed antenatal clinic (ANC) HIV sentinel surveillance data. All 43 sites in the 2005 round of Kenya's ANC surveillance offered opt-out PMTCT services and recorded if women were offered PMTCT HIV testing and whether they accepted or refused. Logistic regression was used to determine the role of participant-level factors on PMTCT acceptance. RESULTS: During the period of sentinel surveillance, 13,026 women attended ANC and testing was offered to 12,030 women. Of those offered testing, 9690 (80.5%) accepted, with a large variation in the percent of acceptors by site. Age, residence and educational status were significant determinants of PMTCT acceptance. However, after adjusting for site none of the participant-level factors were significant determinants of PMTCT acceptance. CONCLUSIONS: Participant level factors were not significant determinants of PMTCT HIV test acceptance after adjusting for sites. PMTCT programmes should collect and evaluate the role of site-level (provider and testing service) factors on PMTCT acceptance. Improvement of site-level factors could improve PMTCT uptake.
