Objective

To determine whether implementation of free cotrimoxazole (CTX) provision was associated with improved retention among clients ineligible for antiretroviral therapy (ART) enrolled in an HIV treatment program in Kenya.

Design

Data were obtained from a clinical cohort for program evaluation purposes. Twelve-month clinic retention was compared among ART-ineligible clients enrolled in the time period before free CTX versus the time period after.

Methods

Statistical comparisons were made using Kaplan–Meier survival curves, log-rank tests, and multivariate Cox proportional hazards models. To exclude potential temporal program changes that may have influenced retention, ART clients before and after the same cut-off date were compared.

Findings

Among adult clients enrolled between 2005 and 2007, 3234 began ART within 1 year of enrollment, and 1024 of those who did not start treatment were defined as ART-ineligible. ART-ineligible clients enrolled in the period following free CTX provision had higher 12-month retention (84%) than those who enrolled prior to free CTX (63%; P < 0.001). Retention did not change significantly during these periods among ART clients (P = 0.55). In multivariate analysis, ART-ineligible clients enrolled prior to free CTX were more than twice as likely to be lost to follow-up compared to those following free CTX [adjusted hazard ratio (aHR) = 2.64, 95% confidence interval 1.95–3.57, P < 0.001].

Conclusion

Provision of free CTX was associated with significantly improved retention among ART-ineligible clients. Retention and CD4-monitoring of ART-ineligible clients are essential to promptly identify ART eligibility and provide treatment. Implementation of free CTX may improve retention in sub-Saharan Africa and, via increasing timely ART initiation, provide survival benefit.

Background

As prevention of mother-to-child transmission of HIV (PMTCT) programs and HIV treatment programs rapidly expand in parallel, it is important to determine factors that influence the transition of HIV-infected women from maternal to continuing care.

Design

This study aimed to determine rates and co-factors of accessing HIV care by HIV-infected women exiting maternal care. A cross-sectional survey of women who had participated in a PMTCT research study and were referred to care programs in Nairobi, Kenya was conducted.

Methods

A median of 17 months following referral, women were located by peer counselors and interviewed to determine whether they accessed HIV care and what influenced their care decisions. Fisher’s exact test was used to assess the association between client characteristics and access to care.

Results

Peer counselors traced 195 (82%) residences, where they located 116 (59%) participants who provided information on care. Since exit, 50% of participants had changed residence, and 74% reported going to the referral HIV program. Reasons for not accessing care included lack of money, confidentiality, and dislike of the facility. Women who did not access care were less likely to have informed their partner of the referral (p=0.001), and were less likely believe that highly active antiretroviral therapy (HAART) is effective (p<0.01). Among those who accessed care, 33% subsequently discontinued care, most because they did not qualify for HAART. Factors cited as barriers to access included stigma, denial, poor services, and lack of money. Factors that were cited as making care attractive included health education, counseling, free services, and compassion.

Conclusion

A substantial number of women exiting maternal care do not transit to HIV care programs. Partner involvement, a standardized referral process and more comprehensive HIV education for mothers diagnosed with HIV during pregnancy may facilitate successful transitions between PMTCT and HIV care programs.
