Nearly a third of MI hospitals - 26 of 81 - received an "A" grade for hospital safety in the spring 2018 report card by The Leapfrog Group, a national nonprofit watchdog organization.
Rush University Medical Center's B grade was partly due to errors in hospital claims data, Dr. Omar Lateef, CEO of Rush University Medical Center, as well as the chief medical officer of the hospital and the health system, said in a statement. Detroit Medical Center had two of its six hospitals on the list as did McLaren Healthcare Corp.in Grand Blanc and St. Joseph Mercy Health System in Ann Arbor.
"Patient safety is the core of our mission at Sebastian River Medical Center and across all Steward hospitals" said Kyle Sanders, President of Sebastian River Medical Center.
Forty-two IL hospitals got the highest grade for patient safety; 30 earned a B; 33 got a C; and five got a D.
The Leapfrog Hospital Safety Grade includes 28 measures, all now in use by national measurement and reporting programs.
UP Health System-Portage in Hancock received an "A" - one of 26 hospitals in MI to get the top rating.
Illinois' drop is due to fewer hospitals in the state achieving an A grade than in previous seasons, said Erica Mobley, director of operations at Leapfrog.
The analysis likely underestimates the number of preventable deaths in hospitals since it only evaluated a subset of safety issues by looking at just 16 safety measures, according to the authors.
Researchers assessed more than 2,600 hospitals receiving Hospital Safety Grades and found that when compared to A-ranked hospitals, patients at D and F hospitals face nearly double the risk of death.
The Leapfrog Group annually releases its "Hospital Safety Grade" each fall and spring, detailing how safe hospitals are across the nation.
"Avoidable medical errors and infections in hospitals continue to be one of the leading causes of death in the US", said Leah Binder, president and CEO of The Leapfrog Group, in a press release.
