In 2002, a research team surveyed state Medicaid officials on state efforts to measure and improve the quality of care delivered to beneficiaries in Medicaid managed care programs.
Specifically, the team sought to assess the states' use of value-based health care purchasing—the term for a broad array of efforts aimed at taking quality as well as cost into account when procuring health care services.
The team, led by Arnold M. Epstein, MD, MA, a professor at the Harvard University School of Public Health, compared the 2002 survey data with data from two similar surveys conducted in 1996 and 1999.
In 2004, the team reported its findings in two articles in Health Affairs. One article focused on state oversight of health maintenance organizations (HMOs), the other on primary care case management programs in Medicaid.
