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 1/30/2023, Dr. van Heeckeren 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. To learn more about Cleveland Clinic's policies on collaborations with industry and innovation management, go to our Integrity in Innovation page.

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.

* Cleveland Clinic physicians and scientists subscribe to the guidance presented in the PhRMA Code on Interactions with Healthcare Professionals and the AdvaMed Code of Ethics on Interactions with Health Care Professionals. As such, gifts of substantial value are generally prohibited.

I called to schedule and appointment with Dr. Makkar, but was scheduled with Dr. Van Heeckeren. I called for clarification and kept the appointment with Dr. Van Heeckeren. I took it as a sign that I was supposed to see Dr. Van Heeckeren and it turned out to be a blessing in disguise!

I cannot begin to express how wonderful Dr. Van Heeckeren is! He is the third Hematologist I've seen at Hillcrest, but only the first to take my condition seriously to the point of wanting to investigate what is causing it. He is incredibly caring and knowledgeable!

I was most appreciative of having the option for this video appointment with Dr. Van Heeckeren. My husband and I definitely prefer in person appointments. In the nearly four years we have been patients at the Cleveland Clinic, this is only the second time we opted for the video appointment. This was a tremendous help - we live nearly 300 miles, one way, from the Cleveland Clinic - requiring a hotel overnight and two, five-hour trips in the car. There were a number of options for an in person appointment, however, given our challenging fall schedule - we were moving from a vacation home in our family for 80 years - this was a great option.
