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 3/22/2024, Dr. Hamaty has reported the financial relationships with the companies listed below. 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.

They were able to fit me in sooner to see Dr Hamaty on a video visit, as I was having blood sugar issues after surgery. I really appreciated the ability to meet him and have my medications adjusted.

Your last question (recommending) most of my family and friends think I'm nuts to travel so far for my health professionals. I've got U of M Hospital and the Henry Ford within 20 miles. I'm going to keep driving the 330 mi. Round trip to have the Dr.s I have it's worth it to me I Used the U of M for 4 yrs and switched, Not At All Sorry!!

Reviewed on Feb 16, 2024

I prefer the face to face but I don't like the drive, I do it because I know it's best for me, putting up with the last ten miles of the drive Is a pain In the Ass. The video visits are second best but Dr. Hamaty gets the blood work he needs done near my home and I believe he's OK with it so I feel OK and it does save me the drive.

A friend recommended Dr. Hamaty to me based on her experiences with him for a different medical issue. I felt very comfortable with this first appointment with Dr. Hamaty.

Dr. Hamaty is an excellent Dr. He knows his field and interacts well with me. He is thorough in his examination and going over my record by highlighting the info I need to know. He is not glued to the computer screen which encourages me to ask questions. He makes eye contact and answers my questions to my satisfaction. I felt his respect for me as a patient by involving me in decisions re my medications and condition. He answers my emails and orders my tests promptly. He and my PCP are the reasons I stay with Cleveland Clinic. The good ones (Dr. Nyalakonda and Dr. Wadhwa) left.
