Mobile clinics for opioid use disorders: What they do and how they do it. A qualitative analysis.

INTRODUCTION: People with substance use disorders (SUD) face many barriers to receiving evidence-based treatments including access to and cost of treatment. People who use drugs face stigma that limits access to traditional office-based clinics. With the goal of reducing morbidity and mortality, mobile clinics reduce many of these barriers by providing harm reduction and on-demand low-threshold medical care. METHODS: In 2020 Massachusetts Department of Public Health (DPH) Mobile Addiction Services Program expanded a program called Community Care in Reach building on its success in reducing barriers to care and increasing patient encounters. In the current evaluation we conducted site visits to the four new mobile clinics and conducted one individual semi-structured provider interview at each of the four clinics. In addition, we supported a monthly learning collaborative of staff in four agencies involved with this initiative. The current evaluation used the RE-AIM framework to analyze the implementation of the mobile clinics. RESULTS: Clinicians described many challenges and opportunities. The typical patient is unhoused, having a substance use disorder, and disconnected from traditional pathways to care. Clinicians are able to initiate people on buprenorphine largely due to the trust they establish with patients. Referral networks are facilitated by established community linkages. The philosophy of care is patient-centered. Mobile clinics provide a wide range of healthcare services including harm reduction, although finding a location to park and relations with police can be challenging. The workflow is uneven due to the model that is built on unscheduled visits. CONCLUSION: This study provides insight into how mobile clinics address the gaps in care for persons with OUD and fatal opioid overdoses. Harm reduction services are a critical intervention and financial sustainability of mobile clinics has to be tested.

Protocol for the implementation of a statewide mobile addiction program.

With overdose deaths increasing, improving access to harm reduction and low barrier substance use disorder treatment is more important than ever. The Community Care in Reach® model uses a mobile unit to bring both harm reduction and clinical care for addiction to people experiencing barriers to office-based care. These mobile units provide many resources and services to people who use drugs, including safer consumption supplies, naloxone, medication for substance use disorder treatment, and a wide range of primary and preventative care. This protocol outlines the evaluation plan for the Community in Care® model in MA, USA. Using the RE-AIM framework, this evaluation will assess how mobile services engage new and underserved communities in addiction services and primary and preventative care.

Mobile Health Services for COVID-19: Counseling, Testing, and Vaccination for Medically Underserved Populations.

Mobile health units can improve access to preventive health services, especially for medically underserved populations. However, there is little published experience of mobile health units being used to expand access to COVID-19 vaccination. In concert with local public health departments and community members, we implemented a mobile COVID-19 health unit and deployed it to 12 predominantly low-income and racial/ethnic minority communities in Massachusetts. We describe the success and challenges of this innovative program in expanding access to COVID-19 vaccination. (Am J Public Health. 2022;112(11):1556-1559. https://doi.org/10.2105/AJPH.2022.307021).

Expanding COVID-19 vaccine access to underserved populations through implementation of mobile vaccination units.

COVID-19 has disproportionately impacted underserved populations, including racial/ethnic minorities. Prior studies have demonstrated that mobile health units are effective at expanding preventive services for hard-to-reach populations, but this has not been studied in the context of COVID-19 vaccination. Our objective was to determine if voluntary participants who access mobile COVID-19 vaccination units are more likely to be racial/ethnic minorities and adolescents compared with the general vaccinated population. We conducted a cross-sectional study of individuals who presented to three different mobile COVID-19 vaccination units in the Greater Boston area from May 20, 2021, to August 18, 2021. We acquired data regarding the general vaccinated population in the state and of target communities from the Massachusetts Department of Public Health. We used chi-square testing to compare the demographic characteristics of mobile vaccination unit participants and the general state and community populations that received COVID-19 vaccines during the same time period. We found that during this three-month period, mobile vaccination units held 130 sessions and administered 2622 COVID-19 vaccine doses to 1982 unique participants. The median (IQR) age of participants was 31 (16-46) years, 1016 (51%) were female, 1575 (80%) were non-White, and 1126 (57%) were Hispanic. Participants in the mobile vaccination units were more likely to be younger (p < 0.001), non-White race (p < 0.001), and Hispanic ethnicity (p < 0.001) compared with the general vaccinated population of the state and target communities. This study suggests that mobile vaccination units have the potential to improve access to COVID-19 vaccination for diverse populations.

Awareness, Utilization, and Preferences of Harm Reduction Interventions among Street-Involved Young Adults in Boston.

OBJECTIVES: This study explores knowledge and utilization of, barriers to, and preferences for harm reduction services among street-involved young adults (YA) in Boston, Massachusetts. METHODS: This cross-sectional survey of YA encountered between November and December 2019 by a longstanding outreach program for street-involved YA. We report descriptive statistics on participant-reported substance use, knowledge and utilization of harm reduction strategies, barriers to harm reduction services and treatment, and preferences for harm reduction service delivery. RESULTS: The 52 YA surveyed were on average 21.4 years old; 63.5% were male, and 44.2% were Black. Participants reported high past-week marijuana (80.8%) and alcohol (51.9%) use, and 15.4% endorsed opioid use and using needles to inject drugs in the past six months. Fifteen (28.8%) YA had heard of "harm reduction", and 17.3% reported participating in harm reduction services. The most common barriers to substance use disorder treatment were waitlists and cost. Participants suggested that harm reduction programs offer peer support (59.6%) and provide a variety of services including pre-exposure prophylaxis (42.3%) and sexually transmitted infection testing (61.5%) at flexible times and in different languages, including Spanish (61.5%) and Portuguese (17.3%). CONCLUSIONS: There is need for comprehensive, YA-oriented harm reduction outreach geared toward marginalized YA and developed with YA input to reduce barriers, address gaps in awareness and knowledge of harm reduction, and make programs more relevant and inviting to YA.

Using mobile clinics to deliver care to difficult-to-reach populations: A COVID-19 practice we should keep.

In the United States, mobile health clinics are an important method for delivering care to medically underserved populations. Mobile clinics have long been used in pediatric primary care, but there is little published to help pediatricians disseminate this practice more widely. During the COVID-19 pandemic, reduced in-person medical visits and subsequent declines in routine pediatric vaccination rates highlighted the importance of using a variety of care delivery models to reach patients. To improve vaccination coverage among young children in Boston during summer 2020, Mattapan Community Health Center and Codman Square Health Center deployed mobile clinics as an adjunct to their in-person preventive pediatric clinical services. In total, the health centers completed 17 mobile clinic sessions and served 50 unique patients, 77% of whom were African-American/Black and 75% of whom were under the age of two. A total of 146 vaccine injections were administered. A quality improvement survey of participating families demonstrated high levels of patient satisfaction and a high likelihood of using mobile services again in the future. The mobile clinic model was most valuable in reaching families who avoided in-person care due to COVID-19 transmission concerns or faced barriers to in-person care. The health centers fostered trust and demonstrated cultural competency during this novel initiative by leveraging established patient-provider relationships, using interpreters, and involving staff who reflected the diversity of the communities. Although there are challenges to implementing mobile health clinics, this initiative demonstrates the value of mobile clinics in delivering high quality pediatric preventive care to difficult-to-reach populations.

Community Care in Reach: Mobilizing Harm Reduction and Addiction Treatment Services for Vulnerable Populations.

Opioid overdoses killed 47,600 people in the United States in 2017. Despite increasing availability of office-based addiction treatment programs, the prevalence of opioid overdose is historically high and disproportionately affects vulnerable populations, including people experiencing homelessness. Despite availability of effective treatment, many at greatest risk of death from overdose experience myriad barriers to care. Launched in 2018, the Community Care in Reach mobile health initiative uses a data-driven approach to bring harm reduction and medication for opioid use disorder directly to those at highest risk of near-term death. Proof-of-concept results suggest that mobile addiction services may serve as a model for expanding access to addiction care for the most vulnerable.

Cost-Effectiveness of One-Time Hepatitis C Screening Strategies Among Adolescents and Young Adults in Primary Care Settings.

Background: High hepatitis C virus (HCV) rates have been reported in young people who inject drugs (PWID). We evaluated the clinical benefit and cost-effectiveness of testing among youth seen in communities with a high overall number of reported HCV cases. Methods: We developed a decision analytic model to project quality-adjusted life years (QALYs), costs (2016 US$), and incremental cost-effectiveness ratios (ICERs) of 9 strategies for 1-time testing among 15- to 30-year-olds seen at urban community health centers. Strategies differed in 3 ways: targeted vs routine testing, rapid finger stick vs standard venipuncture, and ordered by physician vs by counselor/tester using standing orders. We performed deterministic and probabilistic sensitivity analyses (PSA) to evaluate uncertainty. Results: Compared to targeted risk-based testing (current standard of care), routine testing increased the lifetime medical cost by $80 and discounted QALYs by 0.0013 per person. Across all strategies, rapid testing provided higher QALYs at a lower cost per QALY gained and was always preferred. Counselor-initiated routine rapid testing was associated with an ICER of $71000/QALY gained. Results were sensitive to offer and result receipt rates. Counselor-initiated routine rapid testing was cost-effective (ICER <$100000/QALY) unless the prevalence of PWID was <0.59%, HCV prevalence among PWID was <16%, reinfection rate was >26 cases per 100 person-years, or reflex confirmatory testing followed all reactive venipuncture diagnostics. In PSA, routine rapid testing was the optimal strategy in 90% of simulations. Conclusions: Routine rapid HCV testing among 15- to 30-year-olds may be cost-effective when the prevalence of PWID is >0.59%.
