Eric W. Christensen, PhD

Dr. Christensen is the Research Director for the Harvey L. Neiman Health Policy Institute (HPI). Additionally, he is a private consultant and has over 25 years of experience as a health economist. Previously, he was an Adjunct Professor of Health Services Management at the University of Minnesota, led an interdisciplinary research team at the Center for Naval Analyses conducting research for various government agencies, and served as the health economist for Children’s Minnesota hospital system.

Dr. Christensen’s recent research has focused on radiology workforce issues (such as shortages, attrition from the workforce, practice turnover, and subspecialization) and repeat imaging rates for non-physician practitioners compared with radiologists. Some of his other research has focused on the financial viability of the No Surprises Act for clinicians when resolving payment disputes for out-of-network claims, Medicare reimbursement trends, economic drivers of health disparities and the role of reimbursement in disparities, the role of treatment and imaging in cost growth in stroke care, and the association of non-physician practitioners in imaging ordering and interpretation patterns. His research and consulting have covered an array of health care delivery and policy questions from the standpoints of cost of imaging, non-physician practitioners and imaging, accountable care organizations, population health, cost-effectiveness, medical homes, interventions, infrastructure, financial performance under various reimbursement models, demonstrating the value of specific clinical approaches, determining the return on investment, and demonstrating the economic impact of health systems on the local economy.

Dr. Christensen has worked extensively with internal and external stakeholders. In addition to professional conferences, he has presented research and analytic findings to senior government leaders and corporate executives. This includes testimony before U.S. Senate and U.S. House committees, the congressionally appointed Veterans’ Disability Benefits Commission, and the DOD Task Force on the Future of Military Health Care.

Dr. Christensen received his PhD in economics from the University of Illinois. He has a master’s degree in economics from Colorado State University and a bachelor’s degree in business management (finance) from Brigham Young University.
