BACKGROUND: The continued escalation of opioid use disorder (OUD) calls for heightened vigilance to implement evidence-based care across the US. Rural care providers and patients have limited resources, and a number of barriers exist that can impede necessary OUD treatment services. This paper reports the design and protocol of an implementation study seeking to advance availability of medication assisted treatment (MAT) for OUD in rural Pennsylvania counties for patients insured by Medicaid in primary care settings. METHODS: This project was a hybrid implementation study. Within a chronic care model paradigm, we employed the Framework for Systems Transformation to implement the American Society for Addiction Medicine care model for the use of medications in the treatment of OUD. In partnership with state leadership, Medicaid managed care organizations, local care management professionals, the Universities of Pittsburgh and Utah, primary care providers (PCP), and patients; the project team worked within 23 rural Pennsylvania counties to engage, recruit, train, and collaborate to implement the OUD service model in PCP practices from 2016 to 2019. Formative measures included practice-level metrics to monitor project implementation, and outcome measures involved employing Medicaid claims and encounter data to assess changes in provider/patient-level OUD-related metrics, such as MAT provider supply, prevalence of OUD, and MAT utilization. Descriptive statistics and repeated measures regression analyses were used to assess changes across the study period. DISCUSSION: There is an urgent need in the US to expand access to high quality, evidence-based OUD treatment-particularly in rural areas where capacity is limited for service delivery in order to improve patient health and protect lives. Importantly, this project leverages multiple partners to implement a theory- and practice-driven model of care for OUD. Results of this study will provide needed evidence in the field for appropriate methods for implementing MAT among a large number of rural primary care providers.

OBJECTIVE: Effective treatments for opioid use disorder exist, but rural areas of the United States have a shortage of services offering such treatments. Physician bias toward patients with opioid use disorder can also limit care access, but no studies have assessed whether physician bias is a more acute barrier in rural compared with urban communities. METHODS: In total, 408 board-certified physicians in Ohio, a state with a high rate of opioid overdoses, completed an online survey examining perspectives on clinical care for patients who misuse opioids. Respondents with missing county-level data were excluded, leaving a total sample of 274. The authors used t tests to determine rural-urban differences in bias, key predictors of bias, and availability of opioid services. Multivariable regression modeling was used to estimate rural-urban differences in bias independent of key bias predictors. RESULTS: Physicians in rural areas (N=37) reported higher levels of bias toward patients with opioid use disorder than did their urban counterparts (N=237). This difference remained statistically significant even after accounting for known bias predictors and physician specialty. Physicians specializing in addiction medicine reported lower bias than did physicians not working in this specialty. CONCLUSIONS: Given existing disparities in harm reduction and addiction treatment services in rural areas, increased physician bias in counties lacking these services suggests that rural patients with opioid use disorder face numerous challenges to finding effective treatment. Bias reduction interventions should target health care professionals in rural communities where such efforts may have the most pronounced impact on improving health care access.
