Massachusetts General tops U.S. News & World Report's 2012 list of the best U.S. hospitals, knocking Johns Hopkins out of the top spot it's held for 21 years.
The rankings, produced by RTI International, are based on several factors:
Patient survival. On a 1-to-10 scale, this score accounts for 32.5% of a hospital's ranking.
Reputation. Two hundred doctors in each specialty are randomly selected and asked to list the hospitals they think are best in their specialty for complex or difficult cases. This accounts for 32.5% of a hospital's ranking.
Patient safety score. Hospitals are rated on how well they work to prevent the worst kinds of harmful blunders. This accounts for 5% of a hospital's ranking.
Other factors. Care-related factors such as nurse staffing, technology, and other factors linked to quality care account for 30% of a hospital's ranking.
This year, 17 hospitals made the list's honor role. These are hospitals that score at or near the top in at least six of the 16 specialties considered in the ratings.
