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 12/3/2019, Dr. Kessler 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.

Shirley was excellent. She returned messages and made sure that she kept me in the loop as to all my files getting to the doctors, as I requested.

Dr. Kessler is clearly as very smart person. My one concern is that I did have some questions after thinking about what he said that I wish I had thought of at the time. Also, I feel like I am not sure what exactly his plan of action, if any, is. I know he does not want to do surgery right now, and because of the steroids, he cannot do it right now. However, I do hope that after my tests next week, we will have more options, including surgical if necessary, to try and help alleviate the constant pain. If not, then I hope he is willing to help me find a way to manage the pain in a more effective way. Or whether he feels there may be other things I could do to alleviate the pain.

The one thing I had a problem with is that they changed which surgeon was going to assess me two days before I was to be seen. I was originally scheduled with Dr. Dionigi: however, she was apparently leaving the Cleveland Clinic and felt I should see someone else. I feel that it was foolish to schedule me with someone who was going to leave. I wish you had thought this through better...that way, I might have had an easier time getting all the scans, etc. to Dr. Kessler before my appointment.
