Detroit PATHS: Prevention and Access to Treatment, Housing, and Stability - Detroit PATHS is a citywide effort designed to enhance services related to behavioral health, outreach, treatment access, recovery support, and housing coordination. The initiative focuses on adults facing long-term or unsheltered housing instability and youth ages 16–24 who face elevated risk for substance use and loss of stable housing. The project will serve the City of Detroit in Wayne County, providing direct assistance to about 650 participants each year and more than 2,000 over four years. The program will implement a connected set of prevention, outreach, treatment, and housing stabilization strategies. Youth programming will include life‑skills education, community prevention activities, and public awareness efforts. Outreach teams will deliver screening, assessment, intensive case management, peer mentorship, linkage to treatment, medications for opioid use disorder when clinically appropriate, and ongoing recovery support. Housing partners will manage assessments, navigation, coordinated entry referrals, and placement into stable living environments, including permanent supportive, recovery, and transitional options. Key goals include expanding engagement through coordinated outreach, enrolling at least 75 participants per year in individualized treatment, placing at least 25 per year into stable housing, delivering life‑skills training to 100 youth annually, providing crisis‑response training for 250 public safety professionals, conducting community education each year, generating broad public awareness, and maintaining continuous performance monitoring to strengthen outcomes across care, recovery, housing, and system coordination.
