A Systematic Review and Narrative Synthesis Examining the Facilitators and Barriers of Psychological Intervention Delivery in Crisis Resolution Home Treatment Teams

Abstract

BackgroundMental health crisis rates in the United Kingdom are on the rise. The emergence of community mental health models, such as Crisis Resolution Home Treatment Teams (CRHTTs), offers a vital pathway to provide intensive assessment and treatment to individuals in their homes, including psychological interventions. Previous qualitative literature has identified facilitators and barriers to the implementation of psychological interventions within CRHTT settings; however, a synthesis of this literature has not yet been conducted. To address this gap, a systematic review was undertaken with the aim of identifying the reported facilitators and barriers of implementing evidence‐based psychological interventions in CRHTTs.MethodA systematic review and narrative synthesis were conducted. Studies were included if they examined the implementation of evidence‐based psychological interventions in a CRHTT setting. The study population had to be 18 and over and could include healthcare professionals working in CRHTTs, service users of CRHTTs, or family and carers of CRHTT service users. Studies of any formal research methodology were included. Four databases were searched (MEDLINE, CINAHL Plus, Embase and PsycINFO), along with Google Scholar, to identify eligible studies.ResultsSix studies were identified, using mixed qualitative and quantitative methodologies, with the predominant focus being the exploration of stakeholder perspectives on care implementation within CRHTTs, encompassing aspects including but not restricted to psychological care implementation. The literature was deemed to be of moderate to high quality. Facilitators included adapting psychological therapies, prioritizing the therapeutic relationship, increasing psychological skills and training of CRHTT staff and psychologically informed CRHTT models. The barriers identified included a medical model bias within teams, resource constraints and elements pertaining to CRHTT services.ConclusionsFurther robust research in this area is imperative. We recommend that future research be implemented in the form of service evaluations and randomized controlled trials (RCTs) and that the principles of implementation science be used to assess and develop the evidence base for psychological intervention delivery in CRHTTs.
