The case for a medication first approach to the treatment of opioid use disorder.

Background: The opioid addiction and overdose crisis continues to ravage communities across the U.S. Maintenance pharmacotherapy using buprenorphine or methadone is the most effective intervention for Opioid Use Disorder (OUD), yet few have immediate and sustained access to these medications. Objectives: To address lack of medication access for people with OUD, the Missouri Department of Mental Health began implementing a Medication First (Med First) treatment approach in its publicly-funded system of comprehensive substance use disorder treatment programs. Methods: This Perspective describes the four principles of Med First, which are based on evidence-based guidelines. It draws conceptual comparisons between the Housing First approach to chronic homelessness and the Med First approach to pharmacotherapy for OUD, and compares state certification standards for substance use disorder (SUD) treatment (the traditional approach) to Med First guidelines for OUD treatment. Finally, the Perspective details how Med First principles have been practically implemented. Results: Med First principles emphasize timely access to maintenance pharmacotherapy without requiring psychosocial services or discontinuation for any reason other than harm to the client. Early results regarding medication utilization and treatment retention are promising. Feedback from providers has been largely favorable, though clinical- and system-level obstacles to effective OUD treatment remain. Conclusion: Like the Housing First model, Medication First is designed to decrease human suffering and activate the strengths and capacities of people in need. It draws on decades of research and facilitates partnerships between psychosocial and medical treatment providers to offer effective and life-saving care to persons with OUD.

Implementation and evaluation of Missouri's Medication First treatment approach for opioid use disorder in publicly-funded substance use treatment programs.

BACKGROUND: Leaders of Missouri's State Targeted Response to the opioid crisis (STR) grant have prioritized increasing access to treatment medications for opioid use disorder (MOUD) through a "Medication First" approach. This conceptual framework prioritizes rapid, sustained, low-barrier access to MOUD for optimal impact on decreased illicit drug use and mortality. Medication First principles and practices were facilitated through state-level structural changes and disseminated to participating community treatment programs via a multi-pronged, multi-disciplinary approach. In the first nine months of STR, 14 state-contracted treatment agencies operating 38 sites used STR funding to implement the Medication First model. METHODS: We utilized state billing and service data to make comparisons before and during STR on the following outcomes: MOUD utilization, timely access to MOUD, amount of psychosocial services delivered, treatment retention at 1, 3, and 6 months, and monthly price of treatment. We conducted follow-up analyses examining differences across MOUD types (no medication, methadone, buprenorphine, oral naltrexone, mixed antagonist + agonist, and extended release naltrexone). RESULTS: During STR, MOUD utilization increased (44.8% to 85.3%), timeliness of MOUD receipt improved (Median of 8 days vs. 0 days), there were fewer psychosocial services delivered, treatment retention improved at one, three, and six month timeframes, and the median cost per month was 21% lower than in the year prior to STR. All differences were driven by increased utilization of buprenorphine. CONCLUSIONS: Findings suggest Medication First implementation through STR was successful in all targeted domains. Though much more work is needed to further reduce logistical, financial, and cultural barriers to improved access to maintenance MOUD, the steps taken through Missouri's STR grant show significant promise at making swift and drastic transformations to a system of care in response to a growing public health emergency.
