This study investigates the efficacy of a nurse-led mobile phone voice call reminder intervention in improving on-time antiretroviral (ARV) pills collection in Nepal. Between October and December 2017, 468 HIV-positive individuals were recruited randomly and assigned to either nurse-led mobile phone voice call reminder (intervention) group or voice call with health promotion message (control) group, 234 were allocated to each group. We assessed on-time pills pick-up at baseline and six-month follow-up and analyzed it by intention-to-treat method. In the intervention group, participants improved their on-time ARV pills pick-up from 60% (141/234) at baseline to 71% (151/234) at the six-month follow-up. After adjusting for covariates, those in the intervention group were significantly more likely to pick-up their pills on-time than those in the control group (intervention × time; adjusted odds ratio 2.02, 95% CI 1.15-3.55). Nurse-led mobile phone voice call reminder is efficacious to improve on-time ARV collection.
