Barriers to HIV Treatment Adherence: Findings from a Treatment Center in South-South, Nigeria

Abstract

Aims: Non-adherence to treatment represents a significant challenge to anti-retroviral treatment goals. This study aimed to identify and explore perceived barriers to adherence in non-adherent HIV patients attending the University of Port Harcourt Teaching Hospital. Study Design: This was a descriptive, cross-sectional study of HAART experienced patients who had less than 95% adherence to their HAART medication. Place and Duration of Study: The study was carried out between May and June 2011 at the Antiretroviral treatment center of the University of Port Harcourt Teaching Hospital in the Southern part of Nigeria Methodology: Data collection was via quantitative and qualitative methods. A structured interviewer administered questionnaire adapted from the Adult Antiretroviral Clinical Trials Group (AACTG) study was used to identify barriers to adherence. In addition, four focus group discussions (FGDs) were held with 27 purposively selected participants. Quantitative data was analyzed with SPSS version 18, while the FGDs were analyzed using thematic content analysis. Results: Ninety-six (96) patients, 39 (40.6%) males and 57 (59.4%) females with median age of 35.5 years participated in the study. Identified barriers to adherence included; being away from home during medication times 41 (42.7%), being busy with other things 35 (36.5%), forgetfulness 33 (34.4%), running out of pills 25 (26%), difficulty taking pills at specified times 25 (26.0%), the need to avoid side effects 16 (16.7%), and lack of a social support system 15 (15.6%). Barriers identified by the FGDs were fear of taking HIV drugs in front of others, sharing drugs with infected spouse, alcohol use, financial challenges, poor understanding about the effects of the drugs, forgetfulness, long clinic hours and poor attitude of health workers. Conclusion: Adherence counseling, use of reminder systems and treatment supporters are useful Public Health interventions for improving adherence and should be integrated into service delivery at this and other centers. In addition, better organization of the clinic, increasing staff strength and training will go a long way to address these barriers. Decentralization of HIV treatment centers to secondary and primary health facilities needs consideration.
