ABSTRACT OBJECTIVES:: To assess outcomes over the first seven years of antiretroviral therapy at Themba Lethu Clinic, Johannesburg, South Africa. DESIGN:: Observational cohort study. METHODS:: Patients are managed according to South African National Treatment Guidelines. Mortality is ascertained through linkage with the national vital registration system. Loss to follow-up is defined as ≥3 months late for the last scheduled appointment. RESULTS:: Between April 2004 and March 2010, 13,227 patients initiated ART, increasing from 1,794 in the year 2004/5 to 2,481 in 2009/10. Median CD4 at ART initiation increased 39% between 2004 and 2009 (82 vs. 114 cells/mm). The proportion who died within one year on ART was below 11% at all time points, while the proportion lost by one year increased from 8.5% in 2004 to 12.1% in 2009 (RR: 1.42; 95%CI: 1.18-1.71).We followed the 1,794 patients initiated in April 2004-March 2005 through August, 2011 for 8,172 person-years. We estimated 25% of patients were lost and 16% died. The overall mortality rate was 3.59/100 PY (95%CI: 3.20-4.02). Of the 1,577 who completed ≥6 months of follow up, 213 (13.5%) failed first-line treatment in a median (IQR) of 25.9 (15.8-41.4) months on treatment. Of those who failed, 141 (66.2%) switched to second-line for a rate of 48.5/100 PY (95%CI: 41.1-57.2). CONCLUSIONS:: Despite some improvements over seven years, more intervention is needed in the first year on treatment to reduce overall attrition.
