Design outcomes

Primary

MeasureTime frame
Proportion of patients with a cumulative adherence by EAMD >95% at week 48 by arm.

Secondary

MeasureTime frame
Proportion of patients with a viral load of 1000 copies/ml) by week 48. ;Comparison of cumulative EAMD adherence data and tablet count adherence data at weeks 16, 32 and 48. ;Proportion of patients still in care at 48 weeks (excluding those transferred to other ART sites); proportion with a treatment interruption of >72 hours. ;Mid-dosing efavirenz levels or trough nevirapine and lopinavir levels for discordant participants at weeks 16, 32 and 48.;Exploratory endpoint: relationship of PK results to adherence and to virological outcome at week 16, 32 and 48;Acceptability of EAMD device; impact of qualitative issues on adherence (alcohol, disclosure, mental health status, ART tolerability, life events).
