Objective: To identify sociodemographic, clinical, and pharmacological factors associated with nonadherence to antiretroviral treatment in patients with human immunodeficiency virus/acquired immunodeficiency syndrome treated between 2017 and 2020 in four cities in Colombia.
Method: An observational, cross-sectional, retrospective study was conducted of a population of patients with human immunodeficiency virus/acquired immunodeficiency syndrome treated between 2017 and 2020. The Morisky-Green scale, the simplified medication adherence questionnaire, and the simplified scale to detect adherence problems to antiretroviral treatment were applied to determine patient adherence.
