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 12/15/2019, 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.

I have been sick since March and fir the first time since then I am seeing a light at the end of the tunnel!!! Unfortunately dr I was suppose to see was out due to illness but they got me worked in after a 5 hour drive!!!

the doctor didn't talk to me about the results...I didn't understand it

I have already recommended The Cleveland Clinic gastroenterology department to friends. The doctor and the RN were amazing; compassionate, knowledgeable, consummate professionals.

Reviewed on May 8, 2019

It quickly became clear that the doctor had NOT reviewed my chart prior to the appointment, and he spent the lions share of our time looking at the computer while seeming irritated that my information was loading too slowly on his screen. Additionally, his bearing and demeanor were borderline aggressive; when I didn't know or recall specific scientific terms regarding my health issues, he was clearly aggravated. My case deserves his full attention, and that means familiarizing himself with the major aspects of my case and coming to the appointment prepared, rather than baffled and frustrated with the patient and the recalcitrant computer system. I understand his time is valuable, and that he is booked with far too many patients in relation to his ability to adequately juggle them, but I drove five hours and lost the day of work to see him. To be treated as if the doctor's problems arise from my relative inability to quote accurate test results from memory when his computer can't do what he needs; to be rushed through the appointment and feel somewhat bullied by his tone and rapid fire approach; to leave the appointment feeling that I have somehow failed the doctor, and that my decision to seek him out as a second opinion on the care I'm receiving closer to home was damaging to his time and a frustration he'd as soon not have; to leave the doctors's office feeling that my disease is both curiously intractable yet still not worthy of his best efforts; to receive almost no explanation or summary of his thoughts at the end of the appointment, and be told he'd call later, only to be called by his nurse and left a message that he had no further advice for me? What advice did he give at all to be able to say he had none further?

very good Doctor. he explained everything

Reviewed on Mar 20, 2019

Dr. Siddiki was very thorough in trying to determine the cause of my problems. He worked through the diagnosis step-by-step, asking questions, thoughtfully considering the answers, taking the time to go over all my symptoms and past tests. After my procedure, the doctor called me, himself, with the results -- clearing up any questions I may have had. I would highly recommend, Dr. Siddiki, to a friend or relative. Very impressed.
