Key Researchers

  • Medicaid patients with histories of alcohol and drug disorders have elevated hospital and psychiatric admissions, and addiction substantially increases total health care costs (Clark et al., 2009).

    Analysis of Medicaid claims data from Arkansas, Colorado, Georgia, Indiana, New Jersey, and Washington compared medical expenditures among individuals with diagnoses of substance use disorders (n = 43,457) to individuals with diagnoses of mental health disorders (n = 105,000). Substance abuse patients had increased treatment for physical health problems in five of six states, and medical expenditures increased significantly with age (Clark et al., 2009).
