The Mayo Clinic in Rochester, Minnesota, topped the adult hospitals list, which was published Tuesday. Nearly 5,000 hospitals and medical centers were ranked, according to U.S. News. Only New York, Boston and Los Angeles notched more than one facility on the best-of list.
The rankings were based mainly on objective data, such as patient survival rates and nurse staffing, U.S. News said.
Hospitals earned a spot on the Honor Roll if they had very high scores in at least six of 16 specialties, ranging from cancer to urology.
Rankings could differ within the specialties. For example, Memorial Sloan Kettering Cancer Center in New York was first for cancer treatment; Cleveland Clinic for cardiology and heart surgery.
