Outcomes of a mobile medical unit for low-threshold buprenorphine access targeting opioid overdose hot spots in Chicago.

INTRODUCTION: Opioid overdoses in Chicago are unevenly distributed, affecting medically underserved neighborhoods most acutely. Innovations in reaching patients perceived to be hard-to-reach (e.g., unstably housed, marginalized), especially in these underserved neighborhoods, are urgently needed to combat the overdose crisis. This study characterizes the pilot year of a mobile medical unit partnership between a large urban academic center and a community-based harm reduction organization in Chicago. METHODS: This is a retrospective cohort study of all patients who were seen on a mobile medical unit focused on providing low-threshold buprenorphine and primary care in areas with high opioid overdose rates on Chicago's West Side. Treatment episodes were accrued between July 1, 2021, and June 30, 2022 in the first year of operation. The main outcomes were number of patients seen, demographic characteristics of patients, and reason(s) for visit over time. RESULTS: The study saw 587 unique patients on the mobile medical unit between July 1, 2021, and June 30, 2022. Approximately 64.6 % were African American, and more than half lacked active insurance or could not confirm insurance status at the time of visit. The most common reason for initial visit was COVID-19 vaccination (42.4 %), and the most common reason for follow-up visit was buprenorphine treatment (51.0 %). Eleven patients initially presented for other health concerns and later returned to initiate buprenorphine. CONCLUSIONS: The mobile medical unit successfully reached nearly 600 patients in traditionally medically underserved Chicago neighborhoods with the highest overdose rates. The mobile unit's integrated approach met a variety of health needs, including buprenorphine initiation, with a unique opportunity for postoverdose initiation. Several patients initiated buprenorphine after presenting for different health concerns, showing the potential of an integrated approach to build on past mobile outreach programs and reach people with opioid use disorder who are not yet ready to initiate treatment.

Urban Expansion of the SAFE-Home Opioid Management Education (SAFE-HOME) Naloxone Awareness Initiative for Home Health Workers and Older Adults.

The SAFE-Home Opioid Management Education (SAFE-HOME) Naloxone Awareness pilot program utilized home health workers (HHWs) in rural settings to educate older adults prescribed opioids on naloxone access and use. This work expands the SAFE-HOME program to urban settings to prepare HHWs to educate community-dwelling older adults on opioid risks and life-saving naloxone. This prospective, interventional cohort study evaluated 60-min synchronous, virtual HHW educational training sessions describing opioid risks in older adults, opioid overdose signs and symptoms, and naloxone access and use. Knowledge assessments were conducted pre- and post-intervention via a pre-developed assessment tool in a repeated measure model. Outcomes included change in total opioid and naloxone knowledge, and baseline total and individual opioid and naloxone knowledge. Six educational sessions were held (n = 154). The average pre- and post-education scores were 62.7% (n = 108) and 83.5% (n = 82), respectively (p < 0.001). Of the 69 participants who completed both pre- and post-education assessments, the average change in total score was +19.6% (p < 0.001), opioid knowledge score -0.4% (p = 0.901), and naloxone knowledge score +32.9% (p < 0.001). At baseline, HHWs were knowledgeable on opioid risks, but lacked familiarity with naloxone access and use. Targeting HHWs with opioid and naloxone training positions them to effectively educate at-risk community-dwelling older adults.
