Ensuring HIV-infected pregnant women start antiretroviral treatment: An operational cohort study from Lilongwe, Malawi

Abstract

Objectives HIV-infected women identified through antenatal care (ANC) often fail to access antiretroviral treatment (ART), leaving them and their infants at risk for declining health or HIV transmission. We describe results of measures to improve uptake of ART among eligible pregnant women. Methods Between October 2006 and December 2009, interventions implemented at ANC and ART facilities in urban Lilongwe aimed to better link services for women with CD4 counts <250/μl. A monitoring system followed women referred for ART to examine trends and improve practices in referral completion, on-time ART initiation and ART retention. Results Six hundred and twelve women were ART eligible: 604 (99%) received their CD4 result, 344 (56%) reached the clinic, 286 (47%) started ART while pregnant and 261 (43%) were either alive on ART or transferred out after 6months. Between 2006 and 2009, the median (IQR) time between CD4 blood draw and ART initiation fell from 41days (17, 349) to 15days (7,42) (P=0.183); the proportion of eligible individuals starting ART while pregnant and retained for 6months improved from 17% to 65% (P<0.001). Delays generally shortened within the continuum of care from 2006 to 2009; however, time from CD4 blood draw to ART referral increased from 7 to 14days. Conclusions Referrals between facilities and delays through CD4 count measurements create bottlenecks in patient care. Retention improved over time, but delays within the linkage process remained. ART initiation at ANC plus use of point-of-care CD4 tests may further enhance ART uptake. © 2012 Blackwell Publishing Ltd.
