Western Reserve Hospital is the safest hospital in Summit County, according to a new study published by the Leapfrog Group, a nonprofit organization that strives to improve quality, safety, and transparency in U.S. hospitals.

The Leapfrog Group evaluates hospitals twice annually on how well they keep their patients safe from errors, injuries, accidents and infections. The group awarded letter grades to 2,600 hospitals throughout the country, including 112 in Ohio. National performance measures from the following organizations and surveys were used to score hospitals on 30 measures that were used to calculate a letter grade:

Centers for Medicare & Medicaid Services;

Leapfrog Hospital Survey;

Agency for Healthcare Research and Quality;

The Centers for Disease Control and Prevention; and

The American Hospital Association's Annual Survey and Health Information Technology Supplement

Western Reserve Hospital was the only hospital in Summit County to receive a grade of A, according to Leapfrog. Summa Akron City Hospital and Summa St. Thomas Hospital both received C grades and Cleveland Clinic Akron General received a D.

According to Leapfrog, preventable hospital errors are responsible for more than 200,000 deaths each year. Patients visiting hospitals who received a C rating had a 35 percent higher risk of avoidable death compared to hospitals receiving an A rating. At hospitals receiving a D grade, the risk of death by preventable medical error is 50 percent higher, according to the group.
