Mainstreaming Addictions in Medicine: Improving Substance Abuse Services Through Standardization Wilson M. Compton, M.D., M.P.E. Director, Division of Epidemiology, Services and Prevention Research National Institute on Drug Abuse 13 August 2012
Why focus on drug use in general medical settings? Drug use has wide ranging health , social consequences. • Cardiovascular disease, stroke, cancer, HIV/AIDS, anxiety, depression, sleep problems, as well as financial difficulties and legal, work, and family problems can all result from or be exacerbated by drug use. Occurrence of Medical Conditions in Diagnosed Substance Abusers Source: Mertens JR et al, Arch Intern Med 163: 2511-2517, 2003
Why focus on drug use in general medical settings? Health Care Reforms are shifting the emphasis to integrated care based in general medical settings. • 2009 Enhanced parity of coverage of mental illnesses and substance use disorders (compared to coverage of other medical conditions) • 2010 Health care reform to reduce the number of uninsured persons

Why focus on drug use in general medical settings? PROBLEM: Physicians don’t routinely screen for drug use. • Don’t know what to do • No effective treatment • Not medical problem • No time • Health care system doesn’t address addictions routinely
Mainstreaming Addictions in General Medicine • Promising Practice: Screening and Brief Intervention or Referral to Treatments (SBIRT). • Improving development of medications. • Blending science and services to address practice-relevant research.

SBIRT and Cost effectiveness Evaluation of the first SAMHSA SBIRT cohort in Washington state (WASBIRT) Working –age disabled patients Received at least a brief intervention (BI) Results: BI at $70 per person resulted in $185 to $192 saving per member per month and $2.7 to $2.8 million total per year in Washington State Source: Estee S, He L, Mancuso D, Felver B. Medicaid costs declined among emergency department patients who received brief interventions for substance use disorders through WASBIRT.

Electronic Health Record (EHR) • Federal encouragement to adopt with “meaningful use” • Multiple vendors developing EMR • Hospital based systems • Individual practice based systems • Interoperability (EMRs EHR) • Content • Clinical care • Research Source: Robert Gore-Langton, PhD, NIDA CTN Data and Statistics Center, The EMMES Corporation
Electronic Health Record (EHR) • Federal meaningful use criteria • Incentive through reimbursement • Incorporate concepts and data elements to qualify for meaningful use • Example • Meaningful use stage 1 (2011-2012) • Screen for tobacco use in > 50% of clinic population • Meaningful use stage 2 (proposed, for 2013) • Screen for tobacco use in 80% of clinic population • Screen and brief intervention for alcohol use disorders • Screen for illicit and prescription drugs Source: Robert Gore-Langton, PhD, NIDA CTN Data and Statistics Center, The EMMES Corporation

Summary of Future SBIRT Research: • Enhance evidence on effectiveness of SBI models of care in a variety of general medical (and related) settings, and differing populations • Develop and validate brief screening questionnaires, with technology, to detect (and intervene on) prescription drug abuse • Test new technologies for implementing SBI (internet, tablet, PDA, etc.) • Developing models for referral and/or direct treatment in general medical settings (the “RT” of SBIRT) • Integrate SBIRT/Drugs with all behavioral health behaviors
Mainstreaming Addictions in General Medicine • Promising Practice: Screening and Brief Intervention or Referral to Treatments (SBIRT). • Improving development of medications. • Blending science and services to address practice-relevant research.
Outcomes can be improved by: • Developing interventions that are highly effective as delivered
