Linkage to Care Following an HIV Diagnosis in Three Public Sector Clinics in eThekwini (Durban), South Africa: Findings from a Prospective Cohort Study

摘要

Linkage to care following an HIV diagnosis remains an important HIV care continuum milestone, even in the era of universal ART eligibility. In an 8-month prospective cohort study among 459 (309 women, 150 men) newly-diagnosed HIV-positive individuals in three public-sector clinics in Durban metropolitan region, South Africa, from 2010 to 2013, median time to return to clinic for CD4+ results (linkage) was 10.71 weeks (95% CI 8.52-12.91), with 54.1% 3-month cumulative incidence of linkage. At study completion (9.23 months median follow-up), 26.2% had not linked. Holding more positive outcome-beliefs about enrolling in care was associated with more rapid linkage [adjusted hazard ratio (AHR)(each additional belief) 1.31; 95% CI 1.05-1.64] and lower odds of never linking [adjusted odds ratio (AOR) 0.50; 95% CI 0.33-0.75]. Holding positive ARV beliefs was strongly protective against never linking to care. Age over 30 years (AHR 1.59; 95% CI 1.29-1.97) and disclosing one's HIV-positive status within 30 days of diagnosis (AHR 1.52; 95% CI 1.10-2.10) were associated with higher linkage rates and lower odds of never linking. Gender was not associated with linkage and did not alter the effect of other predictors. Although expanded access to ART has reduced some linkage barriers, these findings demonstrate that people's beliefs and social relations also matter. In addition to structural interventions, consistent ART education and disclosure support, and targeting younger individuals for linkage are high priorities.
