Some of our physicians and health professionals collaborate with external pharmaceutical, medical device, or other medical related entities to develop new treatments and products to improve clinical outcomes for patients. In some instances, the physician has ownership interests in the external entity and/or is compensated for advising or speaking about the entity’s products or treatments. These payments may include compensation for consulting and speaking engagements, equity, and/or royalties for products invented by our physicians. To assure objectivity and integrity in patient care, UChicago Medicine requires all physicians and health professionals to report their relationships and financial interests with external entities on an annual basis. This information is used to review relationships and transactions that might give rise to potential financial conflicts of interest, and when considered to be significant a management plan to mitigate any biases is created.
