Habit formation in support of antiretroviral medication adherence in clinic-enrolled HIV-infected adults: a qualitative assessment using free-listing and unstructured interviewing in Kampala, Uganda

Background Despite initial high motivation, individuals receiving antiretroviral therapy (ART) for several years may experience incomplete adherence over time, increasing their risk of HIV-related morbidity and mortality. Habits, defined as automatic and regular practices, do not rely on conscious effort, and may therefore support high long-term ART adherence. Methods This qualitative study contributes to the evidence on how clients with adherence problems remember and form habits to take ART medications. Free-listing and unstructured interviewing were used among 42 clinic-enrolled adults in Kampala, Uganda who were receiving ART and participating in a randomized clinical trial for treatment adherence (clinicaltrials.gov: NCT03494777). Data were coded and analyzed using inductive content analysis. Results Findings indicated that clients’ most routine habits (eating, bathing, sleeping) did not always occur at the same time or place, making it difficult to reliably link to pill-taking times. Efforts to improve ART habits included having a relative to ask about pill-taking, re-packaging medications, leaving medications in view, using alarms, carrying water, or linking pill-taking to radio/prayer schedules. Reported challenges were adhering to ART schedules during changing employment hours, social activities, and travel. Conclusion While habit-forming interventions have the potential to improve ART adherence, targeting treatment-mature clients’ existing routines may be crucial in this population.
