An updated health safety rating by the Leapfrog Group has given the University of Miami and Larkin Community hospitals grades of D, with the three hospitals in the Jackson Health System receiving C’s.

A national organization of large employers dedicated to improving costs, quality and safety of healthcare, Leapfrog on Wednesday updated ratings from last summer. At that time, UM, Larkin and Jackson were listed as “scores pending.”

A Leapfrog spokeswoman said at the time the facilities would have received a D or F, but were given a “grace period” to improve their scores.

The grade summarizes many safety measures, such as frequency of bed sores and patient falls.

Rafael Campo, chief medical officer for the University of Miami Hospital, said Wednesday some of the Leapfrog data was several years old and the hospital has made “significant improvement improvement in quality metrics – especially in the last year.” Campo said that using Leapfrog’s own calculator, the new data would give UMH a grade of B.
