Washington State Medication Assisted Treatment – Prescription Drug and Opioid Addiction Project: Year One Performance

An Evaluation of the Washington State Medication Assisted Treatment – Prescription Drug and Opioid Addiction (MAT-PDOA) Program

This report examines the first year of program implementation of the Washington State Medication Assisted Treatment – Prescription Drug and Opioid Addiction (MAT-PDOA) Project. The program expands access to integrated MAT with buprenorphine for opioid use disorders in Grays Harbor, King and Thurston counties. In year one, the program successfully expanded MAT services by implementing office-based opioid treatment with buprenorphine in one large, urban safety-net primary care setting and two opioid treatment programs. MAT-PDOA treated 211 patients and 77% of those patients were still enrolled in treatment at the end of year one. At six months after enrollment in treatment, MAT-PDOA patients reported reductions in 30-day alcohol and drug use rates, including signification reductions in opioid use, methamphetamine use, and injection drug use. Patients also reported reductions in adverse outcomes related to opioid use disorder, including improvements in self-reported employment and school enrollment, reductions in inpatient and emergency department utilization, and increases in outpatient service utilization six months after enrollment.
