Provider perspectives on antiretroviral therapy adherence among psychiatric inpatients in Botswana.

Background: Optimal adherence to antiretroviral therapy (ART) is crucial for the effective management of HIV. Mental disorders often co-occur with HIV infection which often compromises ART adherence. Little is known about ART adherence in psychiatric settings in sub-Saharan Africa. Aims: This study aimed at exploring the health care providers' perspectives on ART adherence among psychiatric inpatients. The study further assessed the facilitators and strategies enhancing ART adherence in hospitalised psychiatric patients. Methods: In-depth interviews were conducted with 25 health care providers at the Sbrana Psychiatric Hospital in Botswana. Interviews were focused on barriers and facilitators to psychiatric inpatients' adherence to ART, and strategies and recommendations to support adherence. Data were manually analysed using a thematic analysis approach. Results: Key barriers were lack of insight, HIV-related stigma, lack of HIV-related knowledge, antiretroviral side effects and delays in re-initiating ART. Facilitators of ART adherence included motivation to be discharged from the hospital, fear of being sick, peer support, longer duration of hospitalisation, good provider-patient relationships, good diet, privacy and confidentiality and a single-tablet regimen. Health care providers described the various strategies currently used to support adherence, including directly observed therapy and family support, and recommended potential approaches to enhance psychiatric inpatient adherence to ART, including the use of injectable antiretrovirals and the introduction of halfway house centres. Conclusions: Findings from this study revealed unique insights into the numerous factors that influence ART adherence among psychiatric inpatients, and underscore the need to implement tailored strategies to support ART adherence in this population with complex health needs.
