M. Susan Ridgely is a senior health policy researcher at the RAND Corporation and a Pardee RAND Graduate School affiliate faculty member. She has more than 25 years' experience in health services research and policy analysis.
She has led numerous grant and contract projects for government, foundation, and private funders. Her recent research activities include projects on innovation in health care financing, patient safety, and medical liability. She is codirector of the RAND Center of Excellence on Health System Performance, a five-year, multi-institutional center funded by AHRQ to characterize high-performing health systems and identify the most effective ways to promote the uptake of evidence-based practice in health care delivery systems. She is also collaborating on a study modeling health care cost containment options for California.
Ridgely completed studies of the cost and quality performance of California physician organizations, the IHA Bundled Episode Payment and Gainsharing Demonstration, and the Blue Shield of California's Accountable Care Organization (ACO) Infrastructure Grant Program. She was also the RAND principal investigator for the national evaluation of the AHRQ Patient Safety and Medical Liability Demonstration Program.
Ridgely employs site visit, interview, focus group, and survey methodologies to understand changes in the financing and delivery of health care, to derive "lessons learned," and communicate those lessons to policymakers and other stakeholders. She has co-authored over 75 peer-reviewed articles, law review articles, monographs, and reports in the health and behavioral health fields. Ridgely received her J.D. from the University of Maryland School of Law.
