Demonstrating the potential for utilizing mobile methadone units to serve medically institutionalized populations in New York State.

INTRODUCTION

A 2021 federal rule permits opioid treatment programs (OTPs) to provide methadone through mobile medication units (MMUs), creating an opportunity to provide medication for people in residential care facilities. We used simulations to quantify the potential of MMUs to expand methadone access to people residing in residential substance use treatment facilities (RTF), skilled nursing facilities (SNF), and nursing facilities (NF) in New York State under different scenarios.

METHODS

For each facility (RTF, SNF, and NF), a need score was created using three items: facility opioid use disorder (OUD) population, driving distance to nearest OTP, and county overdose mortality rate. We then demonstrated potential patient reach following the launch of 50 hypothetical MMUs making one stop per day to the highest need facilities. In refinements, we examined three additional scenarios involving more daily stops and prioritizing rural areas.

RESULTS

Our sample included 3214 people with OUD estimated to be housed in 1052 facilities in New York, with the majority in RTFs (51.5%). The demonstrated percentage of OUD population served ranged from 23.5% to 35.8%, and the percentage of facilities served ranged from 23.8% to 37.4%. Each scenario reached a large percentage of rural facilities (73-76%). Prioritizing rural facilities decreased the proportion of OUD population served (10% reduction) but did not substantially increase driving time. Allowing multiple stops increased the proportion of OUD population served (32-36% vs. 24-26%).

CONCLUSIONS

Using methods based on location information and spatial relationships, state officials can develop priorities and assess tradeoffs of MMU deployment and distribution strategies.
