The evaluation of the Street Triage (ST) intervention commenced in September 2018 following an extensive stakeholder consultation exercise in January 2018. The University of Plymouth worked alongside partners in Devon and Cornwall Police, Devon Partnership NHS Trust (DPT) and Cornwall Partnership NHS Foundation Trust (CFT) to develop a service evaluation plan. The service evaluation was approved by the University of Plymouth Faculty of Health Research Ethics and Integrity Committee, and was registered with DPT and CFT Research Development Departments. The first stage of the evaluation was conducted from September 2018-March 2019 to support the extension of the intervention into Cornwall. The second stage of the evaluation was conducted from September 2019-January 2020, with the evaluators based in Sentinel Healthcare, to develop a detailed understanding of the intervention.
This service evaluation aimed to provide timely, formative recommendations for the refinement, and development of the new service model. We focused on the mechanisms that are most effective, how the service could be improved and collected and interrogated available data to define the active ingredients and how the intervention works. We additionally conducted focused and timely data collection and analysis to support the extension of ST into Cornwall.
