This document was based on limited experiential evidence. While it evaluated a real-world police-clinician program (NPACER) using operational data, it relied primarily on retrospective electronic records analysis rather than direct experiential accounts from stakeholders (clinicians, police, patients, families) who actually participated in the program.

Overview
This study evaluated NPACER, a combined police and mental health clinician response team in Victoria, Australia.

Did this resource draw on transformative evidence?
This document incorporated some practice wisdom through the development and implementation of the NPACER model by experienced police officers and senior mental health clinicians. However, it primarily used quantitative data analysis rather than systematically capturing the accumulated knowledge, insights, and lessons learned from practitioners in the field.
This document was heavily based on research and evaluation insights. It employed rigorous research methodology including interrupted time series analysis, retrospective data collection over 27 months (N=1776), chi-squared statistical tests, and comparative analysis to systematically evaluate the NPACER program's effectiveness in reducing emergency department presentations.
