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 11/10/2021, Dr. Siddiki 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.

Dr. Saddiki was very nice. This was my first visit with him. He was kind and made a plan to attempt to help me. He took the time to talk by phone with Dr. Ali to get a full picture of my history. He got me in very quickly to have a scope done. The scheduler who made my appt for the scope was kind and she was light hearted. She took her time and found and appt that worked with my schedule. She set up my COVID test and made me feel at ease after I expressed I was nervous about the test. Great job CCF !

I have this procedure done every year and since Dr. Ozuner of Colorectal Surgery moved out of state, I have seen a different doctor each year, but I have now found a new doctor I want to stay with. Dr. Hassan Siddiki was awesome!! took time and explained things even though he had an urgent case come in right before me by and put me at ease.

Dr. Siddiki was very friendly and was very helpful in addressing my questions and it was obvious he was very concerned with my health. His staff was also very friendly and efficient with prepping me for the procedure. One of the staff members walked my wife and I down to the first floor registration office. I'm sorry I can't recall her name but it was above and beyond the call of duty and I am very grateful.
