A randomized controlled trial of a protocol of interviews designed to improve adherence to antiretroviral medications in southern Brazil.
The aim of this study was to evaluate the efficacy of the Portuguese version of the Medication Adherence Training Instrument (MATI) for improving adherence to antiretroviral therapy (ART) in southern Brazil. Two different follow-up modalities were compared in this 225 days randomized controlled study: one based on the MATI protocol and a conventional (non-MATI) clinical follow-up. There were no differences between the groups with the exception of socioeconomic class (P < 0.005). The mean length of continuance in treatment was 111.4 (SD = 13.9) and 137.6 (SD = 17.3) days in the MATI and non-MATI groups, respectively. A Mantel-Cox log-rank test revealed no significant difference between the two interventions (P = 0.34). Despite the sample size limitation, the results from this study indicate that the Portuguese version of the MATI was not more efficacious than the regular follow-up intervention for improving adherence of outpatients to ART.
