Quality? Depends who’s ranking

The lede:

The promise of public quality reporting is undermined by competing sources of information that use different metrics, methodologies and data sources, yielding contradictory and confusing data for patients to sort through, says a study in the November/December 2008, Health Affairs.

Researchers compared how nine 250-plus-bed general hospitals in the Boston area fared on five leading hospital quality reporting services — HealthGrades, Medicare’s Hospital Compare, the Leapfrog Group, U.S. News & World Report‘s “America’s Best Hospitals,” and Massachusetts Healthcare Quality and Cost — and found results were all over the map.

The whole shebang.
