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.

When I started the process to become a patient of Cleveland Clinic, my pain level was a daily 8 out of ten. I had to wait a very long time to get an appointment. Then it was changed. My surgery was scheduled, and the it was hanged. Having said that Dr. Kalfes was one of the best doctors I have had contact with in my lifetime. He is kind and through and makes e feel like I am his only patient he has to think about while he is doing a consult. His assistant, Mary Beth, is kind and knowledgeable, and very professional at the same time.

Dr Kaflas was very solid and to whom I got along with easily during my visit. I believe he astutely understood my situation and his recommendation (muscle relaxants) was an extraordinary insight into my situation, in many ways. I felt very much he was caring about my back situation. Very glad I met with him.

I was in Canada in December and broke my back. After being taking to a clinic there, I was given the option of being admitted there or given medication to fly home and receive treatment here - I chose the later. I never imagined that I wouldn't be able to schedule an appointment with my general practitioner or a specialist for 5 to 6 weeks!!! A BROKEN BACK!!! Thank God for Dr. Kalfas!
