Faculty Profile
J. William Thomas, PhD, MBA
- Professor Emeritus
Bill Thomas is Professor Emeritus of Health Management and Policy, as well as Professor
of Health Policy and Management at the University of Southern Maine in Portland. His
research has focused primarily on measuring performance of health care providers in
terms of efficiency and quality of care.
During the 1980s and early 1990s, his work focused on hospital inpatient care. More
recently, Dr. Thomas has examined methodologies used in the economic profiling of
physicians. In 2002, he completed an evaluation of risk adjustment methods used in
the economic profiling of primary care physicians. In 2004, he finished a study that
focused on methodological issues associated with economic profiling of specialist
physicians, including minimum sample sizes needed for reliable profiles, rules for
attributing responsibility for episodes of care to individual physicians, and methods
for dealing with cost outlier episodes.
Currently, he is working with the RAND Corporation on a study investigating relationships
between measures of physicians' quality of care performance and practice efficiency
performance. He also is working with colleagues at the University of Southern Maine
on a Robert Wood Johnson Foundation grant examining issues associated with use of
tiered provider networks by health plans.
