SOURCE Authors’ analysis of data for 2007–12 from the Truven Health MarketScan Commercial Claims and Encounters Database. NOTES “Parity” refers to the 2010 implementation of the Paul Wellstone and Pete Domenici Mental Health Parity and Addiction Equity Act of 2008. Percentages of characteristics were calculated for the 525,620 people who had twelve-month continuous enrollment in a given year and used any inpatient or outpatient SUD service in that year. Inpatient SUD service outcomes were calculated for the subset of people in the study population who used inpatient SUD services in a given year (during the study period, 49,071 people used these services). Outpatient SUD service outcomes were calculated for the subset of people in the study population who used outpatient SUD services in a given year (during the study period, 516,983 people used these services). Some people used both inpatient and outpatient SUD services. Spending was inflation adjusted using the Consumer Price Index and is reported in 2012 dollars.
