About Our Survey

At University Hospitals, we believe in providing patients with all the information they need to make educated decisions about their health care and to choose the right doctor to meet their needs. That is why we partner with the independent patient satisfaction company Press Ganey to survey patients about their experiences at UH facilities and with UH physicians. We hold ourselves to the highest standards of care and are dedicated to creating a positive patient experience for every individual who sees a UH doctor.

Patient Comments

Reviewed on 5/5/2017
Dr. Cossler remains my absolute favorite doctor who I see at UH. I wish she could be cloned and placed into different medical areas. I have complete confidence in her as a physician and she has an incredibly positive 'bedside manner.' Truly, one of a kind in an exceptional way.

Reviewed on 10/17/2016
I had a 9:45 am appt with Dr Cossler and did not see her until 10:30. There was no offer of an apology for running late. I felt rushed in the brief time I had with her. She was clearly trying to make up for being behind on her schedule. Additionally, I heard her address the nurse as " the patient" when they were outside of the exam room. I've been seeing her annually for a number of years and there was no attempt to even try to remember my name. Having these physicians so overbooked is not good for all parties concerned.

I've been a patient of Dr. Cossler's for 15 years. She is a class act - extremely knowledgeable, informed on current practices, efficient, professional, caring.

Industry Relationships

University Hospitals is committed to transparency in our interactions with industry partners, such as pharmaceutical, biotech, or medical device companies. At UH, we disclose practitioner and their family members’ ownership and intellectual property rights that are or in the process of being commercialized. In addition, we disclose payments to employed practitioners of $5,000 or more from companies with which the practitioners interact as part of their professional activities. These practitioner-industry relationships assist in developing new drugs, devices and therapies and in providing medical education aimed at improving quality of care and enhancing clinical outcomes. At the same time, UH understands that these relationships may create a conflict of interest. In providing this information, UH desires to assist patients in talking with their practitioners about industry relationships and how those relationships may impact their medical care.

UH practitioners seek advance approval for certain new industry relationships. In addition, practitioners report their industry relationships and activities, as well as those of their immediate family members, to the UH Office of Outside Interests annually. We review these reports and implement management plans, as appropriate, to address conflicts of interest that may arise in connection with medical research, clinical care and purchasing decisions.

As of December 31, 2015, Nancy Cossler, MD did not disclose any Outside Relationships with Industry.

There is no publicly available rating for this medical professional because he or she either does not see patients or has not yet received the minimum number of Patient Satisfaction Reviews. To be eligible for display, we require a minimum of 30 surveys. This ensures that the rating is statistically reliable and a true reflection of patient satisfaction.

UH Quality Care Network, is a collaboration among independent and UH employed providers. The focus is on improving the quality and efficiency of care, as well as reducing the cost of care.
