Industry Relationships

Industry Relationships

Cleveland Clinic physicians and scientists may collaborate with the pharmaceutical or medical device industries to help develop medical breakthroughs or provide medical expertise or education. Cleveland Clinic strives to make scientific advances that will benefit patient care and support outside relationships that promise public benefit. In order for the discoveries of Cleveland Clinic physicians' and scientists' laboratories and investigations to benefit the public, these discoveries must be commercialized in partnership with industry. 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.

As of 1/10/2020, Dr. Powell has reported no financial relationship with industry that is applicable to this listing. In general, patients should feel free to contact their doctor about any of the relationships and how the relationships are overseen by Cleveland Clinic.

Public Health Service-Reportable Financial Conflicts of Interest. Cleveland Clinic scientists and physicians engage in basic, translational and clinical research activities, working to solve health problems, enhance patient care and improve quality of life for patients. Interactions with industry are essential to bringing the researchers' discoveries to the public, but can present the potential for conflicts of interest related to their research activities. Click here to view a listing of instances where Cleveland Clinic has identified a Public Health Service (PHS)-Reportable Financial Conflict of Interest and has put measures in place to ensure that, to the extent possible, the design, conduct and reporting of the research is free from bias.

The caregiver that administered the test claims the Doctor would call me the next day with the results, and the test results would be on my chart in a week. I have not heard from Dr. Powell and the test results have not been posted on my chart yet. I see this is the norm for Dr. Powell's office. Same exact thing happened when I had my colonoscopy.

Reviewed on Jul 1, 2021

Dr. Powell is right on when it comes to patient care. He is supportive, friendly and knowledgeable. He is first doctor I've ever encountered who not only read my file and history before seeing me but knew outcomes of previous testing to discuss with me. I was quite impressed by his thoroughness.

This was my first visit with Dr. Gregory Powell. He was patient, a good listener, explained thoroughly, answered all my questions. He treated me as an individual, fashioning his care to conform to my individual needs and lifestyle. He took a conservative approach rather than leapfrogging needlessly to more extreme measures. When the results of the blood test he ordered came out favorably, he messaged me on MyChart ("Great news!"), which I greatly appreciated. I would recommend Dr. Powell highly to anyone with GI symptoms.
