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 10/2/2017, Dr. Donnelly 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 was impressed by Dr. Megan Donnelly's medical knowledge and ability to explain things clearly to me; beyond that, she "won" me in the first 5 minutes by her kindness and the way she took time to really listen. When I return in the future for follow-up care, she is definitely my physician of choice.

Dr. Donnley was extremely professional and very personable. She was very thorough in her exam and the questions that she asked. I felt very confident in her diagnosis.

This provider use to be at a different location close to home. She moved to the main campus and I followed her. That shows the level of trust I have in her.

Dr. Donnelly was excellent! I've never had a doctor spend as much time with me as she did! She thoroughly explained my course of treatment. She listened to everything I had to say and seemed very focused on my treatment going forward. Best experience I've had with a doctor to date.

Dr. Donnelly listened to my concerns and gave recommendations to help.

By far the best physician I have seen in a LONG time. Dr. Donnelly took the time to really understand my condition, make recommendations, ask me my thoughts, involve me in the treatment plan, and followed up via email thereafter. She is excellent.

Dr. Donnelly was amazing. I usually get my GON injections from another NP who wasn't in when I needed them. She put me on her full schedule during her own lunch time and gave me the injections. She did a wonderful job and I feel great again. Thanks Dr. Donnelly for your great care!

Amazing doctor that truly cares for her patients!!

If Dr Donnelly is as caring as she is with me, she is an awesome Fellow/Dr. My chart makes it easy for me to talk to her if I have any concerns about my migraines and I normally get a response from her that same day. So glad I chose to come to Cleveland clinic in Cleveland for my treatment.

Dr. Donnelly is literally the best physician I have ever seen. She genuinely cares and listens, something you can't say about all physicians.

Dr. Megan Donnelly I would say is the best Doctor i have ever had to encounter. I actually feel like she cares for me and my family. This last visit my father came with me bc my wife couldn't make it and he was impressed and said he would travel to her if he ever had a problem. I drive 6 hours to be seen by Dr. Donnelly she wanted to try and help me find a place closer to home. My care under her watch has been so good when i went to the new place it was a complete fail bc the bar is so high. So i no longer go there and back under Dr. Donnelly and always talk her up to friends and family and all PCS chat boards i'm on.

Reviewed on Aug 14, 2017

Dr. Donnelly is also extremely thorough and helpful when it comes to patient care. Every question was answered and I left the office with reassurance. The staff physician was also extremely knowledgeable and made me feel like both of them took the time to review my medical record and get to know the root of the problem. They seem determined to figure out what is going on and to continue care. I would highly recommend Dr. Donnelly who was recommend to me from multiple people as well.
