Mayo Clinic was again ranked No. 1 in the world by Newsweek in its list of the “World’s Best Hospitals,” which was released on Wednesday, March 1. The ranking is a tribute to the work of staff across Mayo Clinic.

“Among the hallmarks of great hospitals … are not just first-class care, first-class research and first-class innovation. The very best institutions also share another quality: consistency,” Newsweek states. “The world’s best hospitals consistently attract the best people and provide the best outcomes for patients as well as the most important new therapies and research. Of all the hospitals in the world, relatively few can do all those things year in and year out. The best belong to a very exclusive club.”

The Newsweek rankings are based on patient survey results, hospital recommendations from peers gathered through an international survey of more than 80,000 health care professionals, and key performance metrics such as patient safety, hygiene measures and quality of care, and patient-reported outcomes.
