Edward Hannan: New York State Cardiac Bypass Reports Improve Survival Rates

Distinguished Professor and Associate Dean Emeritus of the School of Public Health Edward L. Hannan is a nationally and internationally acclaimed leader on health care quality and outcomes. Hannan brings evidence-based medicine to practicing clinicians.

He was one of the first investigators to demonstrate that lower mortality and fewer complications are associated with high-risk cardiovascular procedures when hospitals and surgeons perform higher volumes of these complex procedures.

Since the 1980s, Hannan has been involved in the development and use of clinical and claims databases for cardiac surgery, angioplasty, trauma care, carotid endarterectomy, cancer, and hip fractures. These databases identify significant risk factors for mortality and complications, predict the occurrence of these adverse events, and assess hospital and physician performance.

In the cardiac surgery/angioplasty arena, he has been working with the New York State Department of Health for nearly 25 years to improve quality and access to cardiac procedures. This includes the development of the first clinical database for public reporting of health outcomes in the country and the issuance of annual public reports for cardiac surgery and coronary angioplasty. These reports have been credited with reducing the coronary artery bypass graft (CABG) surgery and angioplasty mortality rates to among the lowest in the country.

Hannan has also been active in conducting numerous comparative effectiveness studies for different cardiac procedures (e.g., CABG surgery and angioplasty, different types of coronary stents, CABG surgery with and without a heart-lung machine) which resulted in the establishment of evidence-based medicine that has led to the development of national cardiac guidelines.

Hannan earned a Ph.D. in industrial engineering and operations research from the University of Massachusetts, Amherst. He is a fellow of the American College of Cardiology, a rare honor for a non-physician, and was named the First Distinguished Visiting Clinical Research Scientist by Duke University.

Hannan has published more than 200 peer-reviewed studies in the New England Journal of Medicine, the Journal of the American Medical Association, the Journal of the American College of Cardiology, Circulation, and numerous other prestigious journals. He currently holds more than $2 million in annual grant funding from New York State, the National Institutes of Health, and the federal Agency for Healthcare Research and Quality.
