Eighteen U.S. hospitals have received consecutive "A" safety grades since 2012, according to The Leapfrog Group's fall safety grades, which were released Nov. 6.
Since 2012, Leapfrog has assigned letter grades to nearly 3,000 acute-care general hospitals across the nation every fall and spring. The safety grades evaluate hospitals' performance on up to 22 patient safety measures from CMS, the Leapfrog Hospital survey and other supplemental sources. The safety grades are the only hospital ratings program solely based on hospitals' ability to protect patients from preventable errors, accidents, injuries and infections.
