Leapfrog Group rankings come twice a year

• Each spring and fall, the Leapfrog Group gives hospitals across the U.S. letter grades for safety and transparency.
• The group uses its scores to determine a hospital’s ability to prevent medical errors or other harm to patients under their care.
• The grading system ranges from “A” to “F,” are based on performance metrics like responsiveness of hospital staff, what technology hospitals use to prevent errors and how often hospital staff make procedural mistakes.

Two of these OP hospitals have earned A’s before

• Last fall, both Menorah and Overland Park Regional Medical Center earned “A’s” from Leapfrog.
• These latest grades mark the sixth and seventh times, respectively, that those two hospitals have earned Leapfrog’s top mark.
• Outside of Overland Park, the only other Johnson County facility to earn an “A” grade this spring was AdventHealth Shawnee Mission in Merriam — marking the hospital’s 20th consecutive “A” rating from Leapfrog.

About 30% of Kansas hospitals got a perfect score
