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 10/9/2020, Dr. Thomas 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.

Visits pretty short with provider. Tests scheduled very close to appointment time with provider and not always available for review. As an out of state patient, I'm very satisfied with the surgery but not sure the followup is worth the trip.

Dr. Thomas and nurse both knowledgeable and forthright. I felt included and cared about, but also got the facts

Dr. Thomas is wonderful. My primary residence is now in Nevada but I would rather travel back to Cleveland for my cardiology check ups than find a new doctor. No one would top Dr. Thomas.

dr Thomas was very thorough and efficient

Reviewed on Mar 16, 2020

Dr. Thomas was a competent and caring cardiologist. She was completely focused on me as her patient - my medical history, my results from other tests and physicians, my concerns. She spent all the time my husband and I needed with her to help us understand my cardiac conditions, new test results, and options for continued care. She welcomed and encouraged an ongoing dialogue with her moving forward. The Cleveland Clinic is fortunate to have Dr. Thomas on their staff.

I have a rare condition with limited research on treatment options and best practices. I appreciate Dr Thomas's transparency and candor. The time spent discussing risks and benefits of each option has been helpful to know that the research I am doing is accurate and there is still not a clear uncontroversial path forward. Very comforting.
