How Leapfrog Calculates Safety Grades

The nonprofit organization released its latest biannual hospital safety report last week, ranking Washington 40th nationally for patient safety. No Washington hospitals received “D” or “F” grades in the report.

These biannual safety grades for patient safety, an 'A, B, C, D, or F,' are assigned to most general hospitals in the United States based on their abiliy to protect patients from errors, accidents, injuries, and infections.

Why Hospital Safety Grades Matter

“The good news is that hospitals across the country are making meaningful strides in patient safety and helping save countless lives,” said Leah Binder, President and CEO of The Leapfrog Group. “But not all hospitals are the same. That’s why it’s so important for people to consult Safety Grades and do their research when choosing a hospital.”

Here are the lowest graded hospitals for safety in the U.S, earning less than a C grade.
