Disclosure of Financial Interests with Industry
Washington University and its physicians are committed to ensuring integrity and objectivity in medical decision-making. Some of our physicians work collaboratively with pharmaceutical or medical device companies to develop innovative ideas and products that can improve health care delivery and clinical outcomes for patients. In some instances, our faculty physicians are paid by these commercial companies to provide advice on product design or to speak about the use of medications, devices, equipment or procedures. These payments may include: a) compensation for consulting and speaking engagements, b) equity, and/or c) royalties for products invented by our faculty. Any payments to Washington University physicians must be based on tangible services and may not exceed fair market value for their work. In addition to disclosure on this web site, physicians earning more than $10,000 per year must disclose their corporate financial relationship in writing to patients when prescribing or using that company's products.
