Dr. Aaron P. Mitchell is an oncologist and health services researcher. He received his clinical training at Duke University Hospital (residency) and at University of North Carolina at Chapel Hill (fellowship). He received an MPH in epidemiology from the University of North Carolina and has completed a postdoctoral research fellowship at UNC’s Cecil G. Sheps Center for Health Services research. Dr. Mitchell’s research focuses on the interaction between financial incentives and physician behavior. He seeks to understand how changes to current reimbursement models for oncology services may be used to achieve better patient outcomes and reduce low-value care. Specifically, he is leading a study to assess the impact of Medicare Accountable Care Organizations on cancer cost and quality outcomes. He previously led an ASCO-funded observational study to assess oncologists’ responsiveness to reimbursement incentives in using high-cost, low-efficacy drugs, and he continues to study physician-level factors associated with use of low-value treatments. His clinical interests are in genitourinary malignancies; he holds a co-appointment in the Genitourinary Oncology Service, treating patients with prostate and bladder cancer.
