Mental health gap action programme (MHGAP) and capacity building of health workers in Mbarara region – western Uganda, a case study of the west Uganda mental health project (WUMHP)

Abstract

The Mental Health Gap Action Programme (mhGAP), initiated by the World Health Organization (WHO), aims to enhance mental health service delivery in low- and middle-income countries by training non-specialist health workers. Despite the implementation of mhGAP in Uganda, a persistent treatment gap continues to pose challenges. This study critically assesses the effectiveness of the mhGAP intervention through a detailed case analysis of the West Uganda Mental Health Project (WUMHP). A mixed-methods, cross-sectional case study design was utilized to gather data from 130 healthcare workers and 40 patients across three districts in Western Uganda (Mbarara, Bushenyi, and Ntungamo) where the WUMHP has been operational. Quantitative data was collected using structured surveys to evaluate service access, provider competency, and medication availability, with subsequent analysis conducted using descriptive statistics via SPSS. Qualitative insights were garnered through focus group discussions to identify implementation barriers and were analyzed employing manual thematic coding. The findings of this study illuminate a significant paradox. Structurally, the mhGAP initiative demonstrated a commendable level of success, with 96.2% of surveyed facilities offering mental health services and 73.1% of health workers receiving training. However, this foundational success was critically undermined by systemic deficiencies. Notably, chronic medication stock-outs plagued 76.2% of facilities, with restocking delays exceeding one month in a substantial proportion of cases. While the knowledge of managing depression among providers was relatively high (81.5% diagnostic accuracy), confidence and competencies in managing acute psychosis and addressing medication side effects were strikingly inadequate (30% accuracy). Additionally, a pervasive lack of clinical supervision was observed, as 93.1% of facilities reported no supervisory visits within a six-month period. Furthermore, a significant disconnect from community-based support systems was evidenced, with 96.2% of facilities indicating absence of collaborative efforts. Patient feedback reflected moderately positive evaluations concerning provider communication; however, access to prescribed medications severely detracted from overall satisfaction, with 27.5% of patients leaving facilities without necessary drugs. Conclusively, the WUMH project successfully established the foundational availability of mental health services within primary care frameworks. Nevertheless, the overall effectiveness of these services remains critically constrained by profound health system weaknesses, including an unreliable pharmaceutical supply chain, inadequate post-training support and supervision, as well as a failure to effectively integrate services with community structures. The study posits that the potential impact of the mhGAP initiative in Uganda is likely to remain unrealized unless implementation strategies evolve from focusing solely on discrete training events towards a more holistic health systems strengthening approach that simultaneously addresses supply chain logistics, promotes continuous clinical mentorship, and fosters deeper community engagement.
