Multi-level Determinants of Starting ART Late in Sub-Saharan Africa (LSTART Study): A Case-control Study to Identify Individual-level Risk Factors for Late ART Initiation in Ethiopia

Background: Although HIV care and treatment programs are being scaled up in sub-Saharan Africa, more than 50% of the patients in need of ART are not receiving it and there is still significant mortality from AIDS. One of the major challenges is high rates of late ART initiation (i.e., in the advanced stages of HIV disease) which results in high rates of mortality soon after initiation of ART. The individual-level factors that contribute to late ART initiation are still unclear. Objective: As the 3rd part of a 3-phase NIH-sponsored project, this study aims to identify individual-level enablers and barriers to timely enrollment into HIV care and ART initiation.

Methods: We will be recruiting all patients newly initiating ART at the study sites for descriptive analysis (approximately 1,200). As a sub-analysis, we will be utilizing a case-control approach to examine potential individual risk factors (e.g. knowledge and behaviors around HIV care and treatment, experience of stigma, and other perceived barriers and enablers to earlier HIV diagnosis, enrollment into care, and ART initiation) among 360 patients who initiated ART late (CD4 count <150 cells/µL compared to 360 patients who initiated earlier (CD4≥200) at 6 HIV care and treatment clinics in Ethiopia. For both the descriptive study and case-control study, data will be collected using 2 methods:

1. Face-to-face interviews with participants using structured questionnaires
2. Abstraction of clinical data from the electronic patient-level database to capture patient information at baseline, 6 and 12 months after enrollment in the study

Expected use of results: Identifying individual-level enablers and barriers of timely ART initiation will facilitate implementation of interventions, programs and policies to mitigate the problem of late ART initiation.
