Tenet Hospitals Receive National Quality Recognition.

Specialty Programs at Hahnemann University Hospital, Saint Louis University Hospital and USC University Hospital Ranked among "America's Best" by U.S.News & World Report

DALLAS -- Tenet Healthcare Corporation (NYSE: THC) announced today that three of its hospitals are included in the July 23, 2007 issue of U.S.News & World Report magazine that lists "America's Best Hospitals" for 2007. The three hospitals, all academic medical centers, are Hahnemann University Hospital in Philadelphia, Saint Louis University Hospital in St. Louis and USC University Hospital in Los Angeles.

Hahnemann University Hospital, a 618-bed teaching hospital that serves as the primary teaching hospital for Drexel College of Medicine, was ranked by the magazine among the Top 50 hospitals in the field of heart care.

Saint Louis University Hospital, a 356-bed quaternary hospital that serves as the primary teaching hospital for Saint Louis University School of Medicine, was ranked as one of the top hospitals in geriatric medicine. Saint Louis University Hospital returned to the rankings this year after receiving similar rankings from 1997 to 2005. U.S. News did not rank hospitals in the field of geriatric medicine in 2006.

USC University Hospital, a 329-bed research and teaching hospital staffed by the faculty of the Keck School of Medicine of the University of Southern California, had two specialty programs ranked by the magazine among the Top 50 hospitals in the fields of ophthalmology and gynecology. USC University Hospital ranked eighth in ophthalmology and has been ranked in the top 10 since 1997. The hospital's gynecology program has been ranked since 2003.

"Only 173 hospitals out of 5,462 across the country scored high enough to receive this prestigious ranking," said Stephen L. Newman, M.D., Tenet's chief operating officer. "We are very proud of the hard work and dedication that our medical staff and employees display each day as they care for our patients."

Jennifer Daley, M.D., Tenet's chief medical officer, said, "These rankings were based on a number of factors that look at data to determine reputation, mortality rates and care-related factors such as nursing and the availability of advanced services. These hospitals have worked hard to ensure that our patients receive the best possible care using evidenced-based medicine designed to improve outcomes."

In addition, 22 Tenet hospitals are among 277 hospitals nationwide that are recognized by the American Heart Association/American Stroke Association in the same issue of U.S.News & World Report for their achievements in the Get With the Guidelines(SM) (GWTG) program to improve patient outcomes and save lives by promoting evidence-based treatments for coronary artery disease (CAD), heart failure and stroke. Most notably, Atlanta Medical Center in Atlanta is recognized for sustaining 85 percent or higher adherence to all CAD performance measures for two or more years.

Three Tenet hospitals - Delray Medical Center in Delray Beach, Fla., Los Alamitos Medical Center in Los Alamitos, Calif. and Saint Louis University Hospital in St. Louis - were also recognized for participating in all three GWTG modules.
