Where are the 20 Leapfrog straight-'A' hospitals?

Twenty U.S. hospitals have received consecutive "A" safety grades from The Leapfrog Group since 2012, according to the group's spring safety gradesreleasedMay 3.

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.

Twenty hospitals have received 23 consecutive "A" grades since the launch.
