As experts in their fields, Cleveland Clinic physicians and scientists are often sought after by industry to consult, provide expertise and education.

To assure professional and commercial integrity in such matters, Cleveland Clinic maintains a program that reviews these collaborations and, when appropriate, puts measures in place to minimize bias that may result from ties to industry. Cleveland Clinic publicly discloses the names of companies when (i) its physicians/scientists receive $5,000 or more per year (or, in rare cases, equity or stock options) for speaking and consulting, (ii) its physicians/scientists serve as a fiduciary, (iii) its physicians/scientists receive or have the right to receive royalties or (iv) its physicians/ scientists hold any equity interest for the physician's/scientist's role as inventor, discoverer, developer, founder or consultant.* In publicly disclosing this information, Cleveland Clinic tries to provide information as accurately as possible about its physicians' and scientists' connections with industry.

I have a history of thyroid cancer and am concerned about recurrence. Dr. Khan had not reviewed my test result history to appreciate the significant changes that were occurring in my TG level, and I had to point that out to her. Dr. Khan could not offer no further explanation for why those changes might be occurring after noting that the most likely cause had been eliminated (negative neck ultrasound). Dr. Khan was not familiar with my tumor pathological history. It seemed that I was the only one concerned about my TG level and she could not tell me why there was nothing to be concerned about.
