Most research looking at self-referral relies on claims data, which cannot determine the appropriateness of the imaging. This enables physicians who self-refer to argue that the patients they treat need these imaging tests more than patients of other physicians do because they are sicker or in greater pain. Researchers affiliated with Duke University Medical Center in Durham, NC, explored this argument and found it wanting.
