Risk factors for discontinuation of buprenorphine treatment for opioid use disorders in a multi-state sample of Medicaid enrollees.
The purpose of this study was to examine duration of buprenorphine treatment for opioid use disorder (OUD) following the initiation of treatment in order to identify risk factors for early discontinuation. Researchers analyzed insurance claims from the MarketScan multi-state Medicaid database for 2013 through 2015; their sample included adults aged 18-64 years who had an OUD diagnosis 6 months before initiating buprenorphine treatment. More than 1/4 of the sample discontinued buprenorphine in the first month of treatment, and most of the sample discontinued before 180 days. Risk factors for discontinuation were associated with significantly lower odds of treatment retention for at least 180 days. The study concludes that there is need to implement treatment models that address barriers to treatment retention more effectively.

Substance use, homelessness, mental illness and Medicaid coverage: a set-up for high emergency department utilization.
The objective of this study was to identify characteristics unique to patients with psychiatric illness who are frequent emergency department (ED) users for mental health care. The authors suggest that understanding unique features of this population could lead to better care and lower healthcare costs. The authors concluded that patients with substance use disorders, homelessness and public healthcare coverage were more likely to be frequent users of EDs for mental illness.

Medicaid benefits for addiction treatment expanded after implementation of the Affordable Care Act.
This study looked at the effects the Affordable Care Act (ACA) had on Medicaid benefits for addiction treatment. The ACA established a minimum standard of benefits and required state Medicaid programs to make changes to their treatment benefits. Researchers surveyed all 50 states and the District of Columbia in 2014 and 2017 when the ACA requirements came into effect. There was a substantial increase in benefits with a decrease in annual service limits of over 50 percent. There was a large reduction in preauthorization requirements for medications to treat opioid use disorder as well as other reductions in preauthorizations.

Service use preceding opioid-related fatality.
The authors analyzed health service patterns before opioid-related death among nonelderly individuals in the Medicaid program, focusing on decedents with and without past-year diagnoses of non-cancer chronic pain. They found that persons dying of opioid-related causes, particularly those who were diagnosed with chronic pain conditions, commonly received services related to drug use disorders and mental disorders in the last year of life, though opioid use disorder diagnoses near the time of death were rare.

North Carolina Medicaid recipient management lock-in program: the pharmacist's perspective.
The objectives of this study were (a) evaluate pharmacists’ perceptions of the implementation of the North Carolina (NC) recipient management lock-in program (MLIP) and (b) determine how the beliefs and attitudes of pharmacists could promote or inhibit its success. It concluded that, although possible improvements were identified, the NC MLIP has strong potential for success as it utilizes pharmacists’ medication gate-keeping role, while minimizing the effort required for successful implementation.

Reducing hospital readmissions among Medicaid patients: a review of the literature.
This review aims to identify factors related to readmissions that are unique to Medicaid populations to inform efforts to reduce Medicaid readmissions. It concluded that much of the Medicaid readmissions literature focuses on patients with mental health or substance abuse issues, who are often high utilizers of health care within the Medicaid population.
