As part of its best hospitals rankings and ratings, U.S. News evaluated more than 4,500 hospitals for their handling of nine surgical procedures and chronic conditions: colon cancersurgery, lung cancer surgery, COPD, heart failure, heart bypass surgery, aortic valve surgery, abdominal aortic aneurysm repair, knee replacement and hip replacement.

In each procedure and condition in which a hospital had treated enough patients to be evaluated, the hospital received a rating of high performing, average or below average. The ratings are designed to help patients and health care consumers make informed decisions about where to receive care for specific medical needs.

Nearly a third of hospitals earned a rating of high performing in at least one procedure or condition. But only the following 57 standouts, barely 1% of hospitals evaluated, got that top rating in all nine.
