Abstract

The study examines impacts of delivery system reforms and Medicaid expansion on treatment for alcohol use disorders within the Oregon Health Plan (Medicaid). Diagnoses, services and pharmacy claims related to alcohol use disorders were extracted from Medicaid encounter data. Logistic regression and interrupted time series analyses assessed the percent with alcohol use disorder entering care and the percent receiving pharmacotherapy before (January 2010–June 2012) and after (January 2013–June 2015) the initiation of Oregon's Coordinated Care Organization (CCO) model (July 2012–December 2012). Analyses also examined changes in access following Medicaid expansion (January 2014). Treatment entry rates increased from 35% in 2010 to 41% in 2015 following the introduction of CCOs and Medicaid expansion. The number of Medicaid enrollees with a diagnosed alcohol use disorder increased about 150% from 10,360 (2013) to 25,454 (2014) following Medicaid expansion. Individuals with an alcohol use disorder who were prescribed a medication to support recovery increased from 2.3% (2010) to 3.8% (2015). In Oregon, Medicaid expansion and health care reforms enhanced access and improved treatment initiation for alcohol use disorders.
