    Chronic Disease and Substance Use Disorders

    UMass Medical School's Center for Health Policy and Research is studying the impact of substance use disorders on asthma and diabetes and the implications for public policy and health care programs.

    These co-occurring conditions are more common among Medicaid beneficiaries than any other insured group. Unfortunately, many disease management programs for people with diabetes and asthma specifically exclude individuals with substance use disorders.

    In preliminary research, UMass Medical School’s Center for Health Policy and Research found that individuals with substance use disorders and asthma or diabetes

    • Are less likely to seek out routine treatment for asthma and diabetes care,
    • Experience more frequent health complications,
    • Experience more severe health complications, increasing risk of hospitalization, and
    • Require longer hospitals stays.

    Furthermore, the research suggests the need for better identification of and intervention for substance use disorders in emergency settings.
