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 11/7/2022, Dr. Wiesen 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.

Dr. Wiesen was wonderful as always. I did not appreciate having an NP run most of my appointment, as I intentionally schedule myself with MDs and DO. Her unexpected presence threw me off and I forgot to mention multiple concerns. She also appeared annoyed that I even saw a GI doctor for my issues, and was concerningly unfamiliar with my history (as in, I don't believe she read the most recent note by Dr. Wiesen).

Reviewed on Apr 27, 2022

Dr. Wiesen made himself available called me at 7:00 pm on a week night to talk to me and advise on endoscopy. His office called me the next morning. After my procedure he spent time with me and my wife Karen and answered all of are questions.His office set up all of my follow up appointment and I am moving forward with my cancer diagnosis.

Everyone was great. I don't like a video conferencing on a first visit so I didn't want that and didn't do that but once I saw the doc it was very good

Everyone from the desk to the nurse and anesthetist to the doctor were great. They made the whole thing feel relaxed and stress free.

Dr. Wiesen came out to greet me before the procedure which I appreciated since we had not met before. Later in the day after my colonoscopy, I called the office with questions about side effects I was experiencing and Dr. Wiesen called me back himself to check on me himself and answer my questions and offered to prescribe me something for my nausea, which I declined. I can tell that Dr. Wiesen cares for his patients.
