The Massachusetts Department of Public Health Post Overdose Support Team Initiative: A Public Health-Centered Co-Response Model for Post-Overdose Outreach.

Context: Post-overdose outreach programs have emerged in response to surging overdose deaths amid fentanyl contamination of the illicit opioid supply. Predominantly centered in police departments in collaboration with public health providers, these programs conduct home-based outreach with survivors and their social networks following an overdose.

Approach: We describe implementation of the Post Overdose Support Team (POST) initiative, an ongoing public health funded and centered approach. Post Overdose Support Team is a person-centered model led by harm reductionists in health and human services agencies in collaboration with municipal first responders. The goal of POST is to engage overdose survivors and their social network to improve general health, connect people to services (including access to treatment, if desired), and reduce risk of subsequent overdose.

Implementation: Nine agencies in Massachusetts that are part of the state's overdose education and naloxone distribution network implemented POST programs, covering 28 municipalities. The POST teams conduct home-based outreach with individuals who experienced an opioid-related overdose to provide a menu of services, including naloxone rescue kits, overdose response and risk reduction planning, referral to treatment for substance use disorders, including medication for opioid use disorder, and referral to recovery and family supports.

Evaluation: From October 2017 to October 2021, the POST teams attempted to reach 5634 overdose survivors via 10 536 outreach visits. Teams successfully engaged 3014 survivors, either directly or through contact with their social network (53.5% success rate). Using data from a real-time encounter-level database, monthly peer-sharing calls with program sites, and annual site visits, we describe the implementation of the POST initiative and provide practice-based recommendations and lessons learned.

Discussion: Early evidence suggests that the POST initiative is meeting its goal to engage overdose survivors, improve general health, and reduce subsequent overdose risk. Future evaluations should examine long-term outcomes among participants, including service linkages and incremental behavior change.
