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 10/3/2021, Dr. Li 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. Li is an excellent physician. She explains step by step what you need to know and readily answers questions. She did cataract surgery on my left eye with extremely fine expertise. She is confident and comforting. I felt much at ease about the procedure she would be doing after meeting her. She will be doing surgery on my right eye in November.

Dr. Li was really great at listening and teaching me about my eye health and glaucoma. Very personable.

Without any hesitation my wife and I would recommend Dr. A. Li.

Reviewed on Jul 15, 2021

Your medical staff are obviously among the best in their field. I am sure doctor Li is excellent. However, considering the fact she was brought into my extremely complicated and difficult case, because of emergent concerns about the speed with which my condition relative to her specialty was progressing, she appeared to have read nothing of the substantial record which had been sent, looked at none of the most recent angiograms or pictures of the optic nerve, or was particularly clear about why she was brought into the case. Since I had an appointment with Dr. S. Srivastava (who is absolutely phenomenal) later, it was not a total waste of time, but having driven 7 hours, in part to see a glaucoma specialist of her caliber, for what the doctor here considered an extremely serious issue, I felt she treated this as a routine first appointment. I would have expected her to have done some level of preparation since we sent a large number of records, reports, and pictures out there weeks in advance. Dr. Srivastava is doing all he can to save my eyesight, and clearly understands the urgency of all medical care, I cannot imagine that was not conveyed to Dr. Li as well, however, I saw nothing beyond a routine first visit. Perhaps my situation is an aberration, since I cannot envision anyone who works at Cleveland Clinic not being the top in their respective fields, but since you asked for an honest evaluation, that is what you get.
