Adherence to HAART: processes explaining adherence behavior in acceptors and non-acceptors

Abstract

In order to explore and clarify the underlying processes which lead to (non)-adherence behavior in patients treated with highly active antiretroviral therapy (HAART), a qualitative study was conducted. Thirty-seven in-depth interviews were held with 30 Caucasian HIV-positive patients. Additional data were collected by diaries kept by some participants. The analysis took place in a cyclic process; selection of themes was alternated with input of new material. Adherence to HAART is mainly influenced by the experience of being HIV positive. Acceptance or non-acceptance of HIV leads to one of two basic stances toward adherence: “being determined to be adherent” or “medication is subordinate to other priorities in life”. This stance determines the commitment to therapy and influences how patients cope with adherence. Patients who are determined to be adherent find solutions to adherence problems. Patients who are not determined to be adherent solve problems only if the solution does not compromise important aspects of their lives. Insight is provided into the manner in which prevalent themes; “start of HAART”, “attitude toward medication”, “HAART in daily life”, “contextual factors”, “health and HAART” and “being informed”, influence adherence behavior. Before starting HAART the focus should be on helping the patient to accept HIV as a part of life. The findings need to be taken into account in adherence-promoting interventions.
