Four University of California medical centers are rated as high-performing hospitals in new rankings released today (May 20) by U.S. News & World Report.

The Best Hospitals for Common Care ratings measure the performance of hospitals in five common conditions or procedures: chronic obstructive pulmonary disease (COPD), congestive heart failure, heart bypass surgery, hip replacement and knee replacement.

UC Davis Medical Center was ranked as a high performer in four areas: COPD, heart bypass surgery, heart failure and hip replacement. UC San Francisco Medical Center ranked as a high performer in three areas: COPD, heart failure and hip replacement. UCLA Health System ranked as a high performer in two areas: heart bypass surgery and heart failure. UC Irvine Medical Center ranked as a high performer in one area: heart failure.

U.S. News created the rankings to help patients find better care for procedures and medical conditions that account for a large percentage of hospitalizations each year. The ratings are based on objective outcome measures such as deaths, infections, readmissions and operations that need to be repeated, along with patient satisfaction data. The ratings also rely on Centers for Medicare and Medicaid Services data for patients 65 and older, as well as survey data from the American Hospital Association and clinical registry data from the Society of Thoracic Surgeons.

“UC Davis is a leader in treating rare diseases and conditions,” said Ann Madden Rice, chief executive officer of UC Davis Medical Center. “I am extremely pleased that these new ratings also demonstrate our high performance in caring for those with the chronic lung, heart and orthopedic conditions that affect thousands in our region.”

The common care evaluations include more than 4,500 hospitals nationwide that were rated as high performers, average or below average. Only about 10 percent of the hospitals were rated as high performers for any condition or procedure.
