A study published in the October 10 issue of JAMA states that patients who have enrolled in the Medicaid managed care appear to receive lower-quality care than patients enrolled in commercial managed care programs.
Although enrollment of commercially insured individuals in health maintenance organizations (HMOs) has decreased in recent years, HMOs continue to provide care for an increasing proportion of the Medicaid population. Between 1994 and 2004, enrollment in Medicaid managed care tripled from 7.9 million beneficiaries to more than 27 million beneficiaries. The proportion of Medicaid beneficiaries in managed care increased from 23 percent to more than 60 percent during the same time period, the authors write. There is limited information in peer-reviewed literature on the quality of care delivered within health plans to Medicaid enrollees.
Bruce E. Landon, M.D., M.B.A., of Harvard Medical School, Boston, and colleagues examined performance on 11 Healthcare Effectiveness Data and Information Set (formerly the Healthplan Employer Data and Information Set) (HEDIS) quality indicators in three types of managed care plans: Medicaid-only plans, commercial-only plans (health plans serving predominantly commercial enrollees), and Medicaid/commercial plans (health plans serving substantial numbers of both types of enrollees). The 11 indicators were in the categories of prevention and screening (such as breast cancer screening); chronic disease management (such as high blood pressure); and care for pregnant women.
The study included 383 health plans that reported quality-of-care data to the National Committee for Quality Assurance for 2002 and 2003, including 204 commercial-only plans; 142 Medicaid/commercial plans; and 37 Medicaid-only plans.
