Peer support for frequent users of inpatient mental health care in Uganda: protocol of a quasi-experimental study

Abstract

BackgroundReducing readmissions among frequent users of psychiatric inpatient care could result in substantial cost savings to under-resourced mental health systems. Studies from high-income countries indicate that formal peer support can be an effective intervention for the reduction of readmissions among frequent users. Although in recent years formal peer support programmes have been established in mental health services in a few low- and middle-income countries (LMICs), they have not been rigorously evaluated.MethodsThis protocol describes a quasi-experimental difference-in-differences study conducted as part of a broader evaluation of the Brain Gain II peer support programme based at Butabika National Referral Hospital in Kampala, Uganda. The primary objective is to investigate whether frequent users of psychiatric inpatient care who have access to a peer support worker (PSW+) experience a greater reduction in rehospitalisation rates and number of days spent in hospital compared to those who do not have access to a peer support worker (PSW-). Frequent users, defined as adults diagnosed with either a mental disorder or epilepsy who have had three or more inpatient stays at Butabika over the previous 24 months, are referred to Brain Gain II by hospital staff on five inpatient wards. Frequent users who normally reside in a district where peer support workers currently operate (Kampala, Jinja, Wakiso and Mukono) are eligible for formal peer support and enter the PSW+ group. Participants in the PSW+ group are expected to receive at least one inpatient visit by a trained peer support worker before hospital discharge and three to six additional visits after discharge. Frequent users from other districts enter the PSW- group and receive standard care. Participants’ admissions data are extracted from hospital records at point of referral and six months following referral.DiscussionTo the best of our knowledge, this will be the first quasi-experimental study of formal peer support in a LMIC and the first to assess change in readmissions, an outcome of particular relevance to policy-makers seeking cost-effective alternatives to institutionalised mental health care.

Acute psychiatric care: approaches to increasing the range of services and improving access and quality of care

“…Formal mental health crisis services also need to be able to move outside of facili ties -for example, providing outreach to those in crisis who are homeless or re strained at home and unable to access care. The potential contribution of peer support to many aspects of mental health care, including crisis response, is gaining traction in LMICs 201,202 , but starts from a low base of involvement and empower ment of people with lived experience of mental health conditions 203 .…”

The effectiveness of volunteer befriending for improving the quality of life of patients with schizophrenia in Bosnia and Herzegovina – an exploratory randomised controlled trial

“…While there have been few studies examining volunteer befriending in other low-and middle-income countries, a group befriending intervention in Colombia for people with severe mental illness was found to be feasible and acceptable (Botero-Rodríguez et al). Globally, peer support interventions, in which patients are matched with volunteers with lived experience of mental illness, Epidemiology and Psychiatric Sciences are attracting increased attention (Ryan et al, 2019) and these programmes have been shown to be sustainable in low-resource settings (Atif et al, 2019). Previous studies of befriending interventions for people with severe mental illness in high-income countries have found a positive effect of these programmes on social isolation and social functioning (McCorkle et al, 2008;Sheridan et al, 2015;Priebe et al, 2020).…”

Orientações sobre Serviços Comunitários de Saúde Mental: Promoção de Abordagens Centradas na Pessoa e Baseadas em Direitos

“…Os alunos são principalmente usuários dos serviços de internação e ambulatoriais do Butabika, embora a Brec também esteja aberta a familiares e funcionários do hospital. A coprodução dos cursos garante que pessoas com experiência vivida tragam seus conhecimentos para a concepção, desenvolvimento e ensino dos cursos oferecidos (454).…”
