Both of Utah's Trauma One centers have been ranked among America's best hospitals in the U.S. News and World Report magazine's 2006 rankings.

University Hospital appeared on the honor roll for the 13th time in the survey's 17-year history, coming in at No. 22 nationwide in gynecology, No. 26 in orthopedics and No. 34 in cancer care.

LDS Hospital made the list in four categories: No. 37 for orthopedic care, No. 41 for treating respiratory disorders and pulmonary medicine, No. 43 for endocrinology or diabetes care and No. 49 for urology. It's LDS Hospital's fourth year on the list.

Of nearly 5,200 hospitals, only 3 percent (176 hospitals) made at least one of the specialty lists. Even fewer were ranked in multiple specialties, as Utah's two centers were.

To make the list, hospitals had to be affiliated with a medical school, hold membership in the Council of Teaching Hospitals, or provide at least nine of 18 key technologies. Hospitals also had to perform a minimum number of procedures in specialty areas. Hospitals that qualified were then scored on their reputation, mortality rate and factors such as nurse-to-patient ratio. The top 50 hospitals in 16 specialties were then ranked based on numerical scores.

Other major centers ranked among America's Best Hospitals by US News & World Report include: Johns Hopkins Hospital, Baltimore; Mayo Clinic, Rochester, Minn; Massachusetts General Hospital, Boston; Cleveland Clinic; UCLA Medical Center, Los Angeles; Barnes-Jewish Hospital/Washington University, St. Louis; New York-Presbyterian University Hospital of Columbia & Cornell; and Duke University Medical Center, Durham, N.C.
