Researchers conducted a process evaluation of Safe Passage, a police deflection model in which police departments become a referral point to treatment for individuals with substance use disorders. Through the model, individuals can walk into any participating police department and request and receive treatment without fear of arrest. In Illinois, Safe Passage has served 170 individuals in rural Lee and Whiteside counties since 2015. Researchers sought to understand how the initiative was developed and operated and gain perspectives of stakeholders, police officers, treatment providers, and clients involved in the program. While more research is needed, the initiative showed promise in its collaborative approach to connecting clients to treatment.
