The Namibia Antiretroviral Therapy (ART) Adherence and Improvement Initiative is a phased approach guiding the implementation of adherence activities in Namibia over the period May 2011 to April 2013. The approach consists of seven implementation phases of
adherence activities. The Namibia ART Baseline Adherence Survey was the first step in this systematic approach, designed to provide the baseline information required for design of cost-effective interventions.
