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.

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.

Fabulous experience with Dr. Hornacek. She was so dedicated to me during my appointment and diagnosed the blood clot that I have. She made sure that I was protected, since I am immunosuppressed, and took extra caution with me while waiting for Xray. She then, was involved with reading my XRay and admitted me to the hospital. Her bedside manner was amazing and knowledge was incredible. I am lucky to be in her hands.

Dr Hornasek was outstanding. I had a very uncommon symptom which required additional testing. She was able to keep me in the department and finish a significant part of the testing and then schedule further testing and a quick follow-up. Also her written notes in my chart were very thorough so I could understand the rare possibilities.

Dr. Hornacek was incredibly thorough. She answered every question. When a medication change was mentioned she helped me with an issue that has been bothering me but I didn't know "who to ask". She gave me helpful explanations and offered suggestions for how I might want to follow up. I was so appreciative of the depth of her concern and how she educated me about my health issues.

Deborah (and all of her staff who handled my case) was EXCEPTIONAL in every way. She was exceptionally kind, pleasant, caring, listened well and responded with excellent explanations and realistic, straightforward information and options, regarding prognosis & medical care for my situation.
