Mobile addiction treatment and harm reduction services as tools to address health inequities: a community case study of the Brockton Neighborhood Health Center mobile unit.

Opioid overdose deaths continue to increase in the US. Recent data show disproportionately high and increasing overdose death rates among Black, Latine, and Indigenous individuals, and people experiencing homelessness. Medications for opioid use disorder (MOUD) can be lifesaving; however, only a fraction of eligible individuals receive them. Our goal was to describe our experience promoting equitable MOUD access using a mobile delivery model. We implemented a mobile MOUD unit aiming to improve equitable access in Brockton, a racially diverse, medium-sized city in Massachusetts. Brockton has a relatively high opioid overdose death rate with increasingly disproportionate death rates among Black residents. Brockton Neighborhood Health Center (BNHC), a community health center, provides brick-and-mortar MOUD access. Through the Communities That HEAL intervention as part of the HEALing Communities Study (HCS), Brockton convened a community coalition with the aim of selecting evidence-based practices to decrease overdose deaths. BNHC leadership and coalition members recognized that traditional brick-and-mortar treatment locations were inaccessible to marginalized populations, and that a mobile program could increase MOUD access. In September 2021, with support from the HCS coalition, BNHC launched its mobile initiative - Community Care-in-Reach® - to bring low-threshold buprenorphine, harm reduction, and preventive care to high-risk populations. During implementation, the team encountered several challenges including: securing local buy-in; navigating a complex licensure process; maintaining operations throughout the COVID-19 pandemic; and finally, planning for sustainability. In two years of operation, the mobile team cared for 297 unique patients during 1,286 total visits. More than one-third (36%) of patients received buprenorphine prescriptions. In contrast to BNHC's brick-and-mortar clinics, patients with OUD seen on the mobile unit were more representative of historically marginalized racial and ethnic groups, and people experiencing homelessness, evidencing improved, equitable addiction care access for these historically disadvantaged populations. Offering varied services on the mobile unit, such as wound care, syringe and safer smoking supplies, naloxone, and other basic medical care, was a key engagement strategy. This on-demand mobile model helped redress systemic disadvantages in access to addiction treatment and harm reduction services, reaching diverse individuals to offer lifesaving MOUD at a time of inequitable increases in overdose deaths.

An economic analysis of the cost of mobile units for harm reduction, naloxone distribution, and medications for opioid use disorder.

Mobile substance use treatment units are effective approaches to increase treatment access and reduce barriers to opioid use disorder (OUD) care. However, little is known about the economic costs of maintaining and operating these units. This study aimed to estimate the economic costs of starting and maintaining mobile units providing harm reduction, overdose education and naloxone distribution (OEND), and medication for opioid use disorder (MOUD). As part of the HEALing Communities Study, four communities in Massachusetts (Bourne/Sandwich, Brockton, Gloucester, Salem) implemented mobile units offering OEND and MOUD (buprenorphine and naltrexone only); each selected different services tailored to their community. All provided MOUD linkage via telehealth, but only one offered in-person MOUD prescribing on the unit. We retrospectively collected detailed resource utilization data from invoices to estimate the direct economic costs from August 2020 through June 2022. Cost components were categorized into start-up and operating costs. We calculated total economic cost over the study period and the average monthly operating cost. Implementing a mobile unit offering OEND and MOUD required a one-time median start-up cost of $59,762 (range: $52,062-$113,671), with 80 % of those costs attributed to the vehicle purchase. The median monthly operating cost was $14,464. The largest cost category for all mobile units was personnel costs. The monthly ongoing costs varied by community settings and services: approximately $5000 for two urban communities offering OEND and MOUD linkage via telehealth (Gloucester, Salem), $28,000 for a rural community (Bourne/Sandwich), and $23,000 for an urban community also providing in-person MOUD prescribing on the unit (Brockton). The economic costs of mobile substance use treatment and harm reduction units are substantial but vary by community settings and services offered. Our results provide valuable community-level economic data to stakeholders and policymakers considering establishing and/or expanding mobile units with OEND and MOUD services. Further exploration of cost-effectiveness and efficiency should be considered across different settings.

The Mobile Overdose Response Program: A mobile, low-threshold opioid use disorder treatment model in Philadelphia.

Low-threshold substance use treatment programs may help overcome barriers for marginalized individuals. The aims of this study were to 1) describe participant characteristics and treatment outcomes for a multi-site, Philadelphia-based mobile program providing street-based buprenorphine initiation, stabilization, and referral to ongoing care and 2) examine associations between patient characteristics and successful linkage. We conducted a retrospective cohort study of patients receiving buprenorphine through Prevention Point Philadelphia's mobile overdose response program from 9/2020-12/2021. We abstracted electronic medical record data, including patient characteristics, mobile program treatment, and care linkage. We used descriptive statistics to characterize the sample and assessed the association between patient characteristics and successful care linkage using multi-variable logistic regression. Two hundred thirty-seven patients initiated buprenorphine in the program across six sites. Mean age was 46. Participants were majority men (67 %); 59 % identified as Black, 33 % identified as White, and 15 % reported Hispanic ethnicity. Most were publicly insured (74 %) and 30 % were unstably housed. Basedline engagement in primary care (32 %), psychiatric treatment (5 %), and counseling (2 %) were low. Most participants reported heroin or fentanyl use at intake (87 %), with high rates of IV drug use (37 %)., and co-occurring substance use and prior buprenorphine treatment experience were common.. 86 % completed ≥1 mobile follow-up visit, and 69 % completed ≥4 mobile program visits. 51 % of patients attended at least one visit at an outside site, and 30 % had ≥2 visits for buprenorphine prescriptions at an outside site. 35 % of the referrals were internal, meaning they went to University-based practices staffed by the mobile unit physicians. In a multivariable logistic regression model, internal referral was associated with significantly increased odds of effective care linkage (aOR 2.47, 95 % CI 1.20-5.09). Targeted community outreach with low-threshold substance use care facilitated treatment access among marginalized individuals. Participants showed high levels of engagement with the mobile program, but rates of outside care linkage, while comparable to retention in other low-threshold models, were lower. The only predictor of effective care linkage was referral to brick-and-mortar clinics staffed by mobile unit physicians. These findings support the importance of outreach beyond traditional health care settings to engage high-risk patients with OUD.
