Dueling ‘Best Hospital‘ Ratings

March 29, 2011 -- U.S. News & World Report has released its list of the best hospitals in 52 U.S. cities on the heels of Thomson Reuters' "100 Top Hospitals" list.?

The two companies have released dueling "best-hospital" lists for years. U.S. News & World Report releases its top-hospitals list over the summer, while the Thomson Reuters list comes out in the spring.

But this year, U.S. News & World Report has a surprise. Building on data from its 2010 "best" list among the nation's 4,852 hospitals, it's now offering a list of the best hospitals in U.S. cities with a population of 1 million or more.

Hospitals that make the U.S. News & World Report metro list are ranked first by the number of medical specialties in which they are among the best in the nation. Then they are ranked by the number of medical specialties in which they score among the top 25% of all U.S. hospitals.

Hospitals with at least one national ranking outscore hospitals that may be better in various other specialties but aren't nationally ranked in any of them. Children's hospitals are not included in the report.

"Consequently, the No. 1 hospital in a metro area is not necessarily the best in town for all patients," notes U.S. News & World Report editor Avery Comarow in a news release. "We expect that savvy consumers will consider not merely a hospital's overall rank in the metro area, but its expertise in the specialty relevant to their care."

Given this warning, here's the list from U.S. News & World Report of the top-ranked hospitals in the five largest metro areas:

New York City

1. New York-Presbyterian Hospital of Columbia and Cornell
2. NYU Langone Medical Center
3. Mount Sinai Medical Center
4. Memorial Sloan-Kettering Cancer Center
5. Hospital for Special Surgery

Los Angeles

2. Cedars-Sinai Medical Center
3. USC University Hospital

Top 100 U.S. Hospitals

The Thomson Reuters ratings use a very different system. The report considers 2,914 non-federal U.S. hospitals.

The report evaluates hospitals according to 10 criteria: deaths; medical complications; patient safety; average patient stay; hospital costs per patient; hospital profitability; patient satisfaction; adherence to clinical standards of care; post-discharge mortality; and death and readmission rates for acute myocardial infarction (heart attack), heart failure, and pneumonia.
