Transforming first response through non-police, community safety response programmes: a peer-reviewed and grey literature scoping review protocol.

introductionPolice are frequently dispatched to a wide range of 911 calls, including mental and behavioural health crises, despite lacking the training, resources and time to respond effectively. In particular, people with serious mental illness are at elevated risk of experiencing excessive use of force, arrest and continued criminal legal involvement following police contact. Following the murder of George Floyd and other highly publicised police killings, Community Safety Response (CSR) programmes, staffed by unarmed peers, mental health professionals and other trained responders, have proliferated to provide non-police responses to mental and behavioural health and other quality-of-life concerns. CSR programmes have expanded rapidly, yet the evidence base remains fragmented and largely outside the peer-reviewed literature. METHODS AND ANALYSIS: This scoping review will synthesise peer-reviewed and grey literature from 2020 to present on CSR programmes operating in North America. Guided by Joanna Briggs Institute methodology and reported according to Preferred Reporting Items for Systematic Reviews and Meta-Analyses Extension for Scoping Reviews (PRISMA-ScR) standards, we will search multiple databases (Medline, PsycINFO, Embase, SocIndex, Web of Science, Policy Commons) and employ complementary grey literature search strategies, including targeted website searches, reference tracking and review of internal and external reports and evaluations. Inclusion criteria require that programmes provide non-police first response to calls traditionally served by law enforcement and include information on programme operations or outcomes. Two reviewers will independently screen and extract data on process metrics including operational characteristics, dispatch, funding, services provided and outcomes such as populations served, diversion from police, service linkage and use of force. ETHICS AND DISSEMINATION: No ethical review for this study is required as it will not include human subjects or any identifiable information. Findings will provide the first national synthesis of CSR programme models, operations and outcomes. Results will inform policy-makers, practitioners, researchers and community members. Findings will be disseminated through peer-reviewed publications and public-facing products to support implementation, scale-up and sustainability of CSR programmes.
