Medicaid reimbursement rates for primary care services and behavioral health outcomes.
This AHRQ-authored research studied the effects of changing Medicaid reimbursement rates for primary care services on behavioral health outcomes-defined here as mental illness and substance use disorders. The authors applied two-way fixed-effects regressions to survey data specifically designed to measure behavioral health outcomes over the period 2010-2016. They found that higher primary care reimbursement rates reduce mental illness and substance use disorders among non-elderly adult Medicaid enrollees, although they interpreted findings for substance use disorders with some caution as they may be vulnerable to differential pre-trends. Overall, their findings suggest positive spillovers from a policy designed to target primary care services to behavioral health outcomes.

Medicaid managed care: access to primary care providers who prescribe buprenorphine.
This study examined variation in access to in-network buprenorphine-prescribing primary care providers that can treat opioid use disorder among Medicaid managed care enrollees. Approximately 32.2% of Medicaid enrollees had fewer than one in-network network buprenorphine-prescribing primary care providers per 100,000 county residents. There was on average a greater number of in-network buprenorphine-prescribing primary care providers in states with higher compared with lower overdose death rates, but most enrollees lived in areas with a shortage of these providers. The authors found that a 25 percent higher network participation rate by prescribers compared with nonprescribers could improve the probability that enrollees see a prescriber by approximately 25 percent.

Integrated care models and behavioral health care utilization: quasi-experimental evidence from Medicaid health homes.
This study provided the first population-level evidence on the effects of Medicaid health homes (HH) on behavioral health care service use. As of 2016, 16 states had adopted an HH for enrollees with serious mental illness and/or substance use disorder. Using data from the National Survey on Drug Use and Health, the authors found that HH adoption increased service use among enrollees and enrollee self-reported health improved post-HH.

Rural access to MAT in Pennsylvania (RAMP): a hybrid implementation study protocol for medication assisted treatment adoption among rural primary care providers.
This paper reports the design and protocol of an implementation study seeking to advance availability of medication-assisted treatment (MAT) for opioid use disorder (OUD) in rural Pennsylvania counties for patients insured by Medicaid in primary care settings. Results showed 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. Further, 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.

The role of primary care in improving access to medication-assisted treatment for rural Medicaid enrollees with opioid use disorder.
The authors examined the degree to which rural residents with opioid use disorder (OUD) are engaged with primary care providers (PCPs); they also described the role of rural PCPs in medication-assisted treatment (MAT) delivery, and estimated the association between enrollee distance to MAT prescribers and MAT utilization. They concluded that PCP utilization among rural Medicaid enrollees diagnosed with OUD is high, presenting a potential intervention point to treat OUD, particularly if the enrollee's PCP is located nearer than their MAT prescriber.
