Abstract
Recent research has shown that very high levels of adherence are required to obtain the maximum benefit of highly active antiretroviral therapy (HAART). This situation justifies the importance of developing efficient strategies to improve adherence to drugs against HIV. A comprehensive range of factors are the targets of the most effective interventions to improve adherence, including cognitive, behavioral, emotional, and social aspects. The authors describe three theoretical models that can help identify barriers and guide interventions. Most of the interventions are complex and may include more convenient care, provision of information, counseling, reminders, reinforcement, self-monitoring, family therapy, or additional supervision or attention. The authors suggest aspects that should be included in interventions to promote adherence based on a review of the literature and clinical experience. Limited evidence suggests that interventions to enhance adherence to antiretroviral therapy in people with HIV are most likely to be successful when they are comprehensive, longitudinal, and tailored to the person.
