Many HIV-infected patients fail to achieve undetectable viral load and are not retained in care. This pilot study examined patients lost to care in public and private clinics in Buenos Aires, Argentina. The impact of patient and provider interventions was compared separately and collectively. In Phase 1, participants prescribed antiretrovirals and non-adherent to treatment in the prior 3–6 months (n = 60) were randomized to patient intervention or standard of care (SOC) and assessed over 12 months. In Phase 2, providers were trained in interviewing techniques and 60 additional patients were randomized to patient intervention or SOC condition. Averaged across patient intervention status, Phase 2 provider intervention patients reported the most improved adherence and viral suppression at 6 and 12 months. Adherence in “patient intervention only” improved at midpoint and returned to baseline at 12 months. Results suggest provider training sustained patient adherence and viral suppression among “hard to reach” patients.
