Management of depression in people living with HIV/AIDS in Senegal: Acceptability, feasibility and benefits of group interpersonal therapy

Costs analysis of integrating group interpersonal therapy into HIV care services in Senegal

INTRODUCTION

Group Interpersonal Therapy (IPT), an evidence-based treatment of depression recommended by the WHO mhGAP Intervention Guide, was implemented through a task-shifting approach in Senegal, as a treatment for depressed people living with HIV (PLWH). Since a description of the resources used and the implementation costs incurred is necessary to inform policymakers better, this study aimed to estimate the costs associated with its implementation.

METHODS

Intervention costs were analyzed using an "ingredients-based costing approach" from the provider's perspective. We identified and described the start-up and implementation costs for the initial phase and a projection over 5 years (implementation at capacity). We estimated total annual costs and cost per beneficiary. We conducted a scenario analysis to highlight some cost uncertainties and their impacts.

RESULTS

The total annual costs were estimated at $4064 for the initial phase and $8161 for the implementation at capacity. The training was the main cost driver representing approximately 60% of the total annual costs. The cost per beneficiary receiving group IPT was estimated at $65 for the implementation at capacity. The scenario analysis also illustrated the importance of parameters like the screening strategy, training activities, and allocation to cover transport costs mobilized by participants.

CONCLUSION

This cost analysis highlighted the costs and cost allocations required to implement group IPT in Senegal to treat depression in PLWH. This preliminary work should enable policymakers to identify the optimal resources to be mobilized to implement and ensure the sustainability of this therapy in HIV at a country-level program.

Effectiveness and acceptance of group therapy as a mental health intervention for people living with HIV in Africa - a scoping literature review

Mental health problems are highly prevalent among people living with HIV/AIDS (PLWHA), yet mental health care in African countries is scarce. There is growing interest in understanding the effect of group therapy delivery models and task-shifting to support mental health care in African settings. We conducted a scoping review following the PRISMA-ScR statement on group therapy in PLWHA in Africa. We searched PubMed/Medline, Embase, and Google Scholar for articles published before October 2023 on evidence for effectiveness and acceptance of group therapies in PLWHA, and evidence of task-shifting approaches. A narrative synthesis approach for data analysis was used. We included 17 studies, which comprised 26 different outcome measures across seven countries in sub-Sahara Africa. The majority (72%) of the assessed single outcomes demonstrated a positive impact of group therapy delivery models on outcome measures, particularly depression, alcohol use, overall functioning, and social support in sub-Sahara Africa. High acceptance was demonstrated by quantitative and qualitative approaches. Task shifting approaches generally were shown to be effective, cost-effective, and accepted, and may support burdened healthcare systems in rural settings. The current evidence, albeit scarce, supports the use of group therapy and task shifting in addressing mental health among PLWHA living in sub-Sahara Africa.

Perceptions, facilitators and barriers to the implementation of interpersonal group therapy to treat depression among people living with HIV in Senegal: a qualitative study

Background

Depression is highly prevalent in people living with HIV (PLWH) but remains under treated in Sub-Saharan Africa. In this context, we conducted the first study of Group Interpersonal Therapy (IPT) to treat depression in PLWH in Senegal. We assessed the perceptions and experiences of patients and group facilitators, as well as barriers to implementation.

Methods

This study was conducted at the Fann National University Hospital Center in Dakar, the urban capital of Senegal. Qualitative data were collected during the implementation phase (February to June 2020 and then from January to February 2021), with a 6-month pause due to the COVID-19 pandemic. Twenty-five patients and three group facilitators were individually interviewed by a socio-anthropologist. Qualitative data were analyzed thematically.

Results

Group IPT was perceived as successful and beneficial by patients and facilitators. Patients reported positive experiences with group IPT and sustained outcomes. Beyond improving depressive symptoms, patients reported improvements in their social and professional lives, and the development of skills to prevent relapse. Group facilitators noted the benefits of therapy for their patients and for their professional skills, reporting greater clinical competence and improved supportive skills. Challenges to intervention implementation included confidentiality and patient privacy concerns, healthcare accessibility issues, and time demands.

Conclusion

In this first qualitative study of group IPT for depression in PLWH in Senegal, participants described both positive experiences with the intervention and challenges to its implementation. Future studies, conducted in suburban and rural communities outside of Dakar, would further inform the implementation of IPT in Senegal.
