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.

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.

I had a question for the Dr. And they called me back quick and were very helpful

Reviewed on Jun 25, 2021

Dr Rensel is just awesome. I feel so confident and secure in her care. From the very first moment I met her she was a source of comfort for me; her expertise and her compassion were just what I needed at a difficult time. She has listened to me, given me all the time I have needed, it's just been such a great experience, in spite of a very scary diagnosis and uncertain future. It means the world to me to be in her expert care.

Dr. Rensel is a blessing to our family. We appreciate her support and guidance.

Reviewed on Jun 4, 2021

Excellent, doctor who really listened to my health concerns, answered my questions and she didn't rush my visit after my being late for my appointment. That kind of treatment goes a long way, my old MS nurse practitioner need some patient interaction and/or communication courses. Then when the doctor you never met, meets you once (by your request) sides with her team instead of trying to cover it up. Cleveland Clinic large staff should provide and require their staff mandatory training.
