ABSTRACT
OBJECTIVE: To evaluate various strategies aimed at improving adherence to antiretroviral therapy (ART). METHODS: Patients initiated on ART at Muhimbili National Hospital HIV clinic were randomly assigned to either regular adherence counseling, regular counseling plus a calendar, or regular counseling and a treatment assistant. Patients were seen monthly; during these meetings self-reported adherence to treatment was recorded. Disease progression was monitored clinically and immunologically. RESULTS: Of the 621 patients randomized, 312 received regular counseling only, 242 regular counseling and calendars, while 67 had treatment assistants in addition to regular counseling. The mean (SD) follow-up time was 14.5 (4.6) months. During follow-up 20 (3.2%) patients died, and 102 (16.4%) were lost to follow-up; this was similar in all groups. In 94.8% of all visits, patients reported to have adhered to treatment. In only 39 (0.7%) visits did patients report a < or = 95% adherence. There were no differences in adherence (P = 0.573) or differences in CD4 count and weight changes over time in the interventions. CONCLUSIONS: Good adherence to ART is possible in resource constrained countries. Persistent adherence counseling in clinic settings by itself may be effective in improving adherence to ART.
