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 11/8/2021, Dr. Thomas 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.

Would prefer to see Dr. George more than once in order to ascertain if I would suggest him to another person. So far so good. I felt comfortable with his suggestions at our one and only visit. He was interested, explained reasons for changing my medications, ordered appropriate labs.

Dr. Thomas was great when I saw him in 2016 for blood pressure. He was so informative and very thorough. This appointment was somewhat disappointing, I still have questions and concerns about my symptoms. Not sure if I should contact his office or just go with mu pcp. It's a bit frustrating.

I indicated "very good" but honestly, the way I got my appointments scheduled via Dr. Ha as part of a broader attempt to diagnose an issue with multiple specialists, I didn't have to do any of this. There was not an N/A option.

Reviewed on Oct 4, 2021

This appointment was set as one in a series of other specialists. It didn't seem that my issue was a direct Nephrological issue when it was all said and done, but I appreciated Dr. Thomas' ability to confirm this by thoroughly reviewing all of my previous labs. He also suggested a few tests that might help with a secondary symptoms. But most of all, I appreciate his demeanor. As I told him, I felt "heard" after a long time. He reiterated what I had said in a way that confirmed he understood which few other doctors have over the past two years (and there have been many). I found him to be very compassionate and knowledgeable.

I saw Dr George Thomas and was very impressed with him. I was treated like a thinking person, one able to assimilate information and make reasonable decisions. Where I asked for clarification, Dr Thomas as very accommodating and re-phrased the material so I understood to my satisfaction. I am really glad Dr Thomas is my physician, and I put a great deal of confidence in his advice.

I brought up a facial acne condition that I thought was caused by a new medication. The doctor listened to my concern and noted it in his visit summary. This hopefully will be reviewed by my PCP.

Overall a good experience. However, I wish someone had told me about the not being able to get In the door to Gllickman. I don't usually use the downtown campus and I had no idea where to park and there wasn't anyone to ask. I love Dr Thomas but I will be seeing him at Avon unless it is an emergency.

I have been seeing Dr George Thomas for 10 years. He has always been kind, informative and professional.
