Mount Sinai South Nassau has earned an A grade for patient safety in the elite national patient safety ratings system administered by The Leapfrog Group and developed under the guidance of the nation's leading patient safety experts. Leapfrog assigns an A, B, C, D, or F grade to general hospitals in the nation, using evidence-based measures of patient safety focused exclusively on errors, accidents, injuries, and infections.
Mount Sinai South Nassau, along with Mount Sinai Queens, is one of 11 hospitals in New York and 917 nationwide to receive an A for the 2026 spring cycle of the Leapfrog Hospital Safety Grade. Mount Sinai South Nassau is also a recipient of the 2026 Patient Safety Excellence Award from Healthgrades and was named to its 100 Best Hospitals for Coronary Intervention Award for a third consecutive year.
Considered the gold standard for patient safety, the Leapfrog Hospital Safety Grade is the only hospital ratings program focused on preventable medical errors, infections, and injuries that claim the lives of more than 500 patients each day in the United States. The program is peer-reviewed, fully transparent, and free to the public. Grades are updated twice annually, in the fall and spring, and are designed to give consumers information they can use to protect themselves and their families when facing a hospital stay.
Founded in 2000, The Leapfrog Group is a national nonprofit organization driving a movement for giant leaps for patient safety. The group's Hospital Safety Score analyzes at least 30 measures of publicly available Centers for Medicare and Medicaid hospital safety data to produce a single A, B, C, D, or F score, which represents a hospital's overall capacity to keep patients safe from preventable harm. More than 3,000 U.S. general hospitals were evaluated this cycle.
The Hospital Safety Score's website, www.hospitalsafetygrade.org, provides an analysis of the data and methodology used in determining grades.
Patients can also compare each hospital's past safety performance with its current grade on the website, helping them to identify local hospitals with strong patient safety track records and consistent improvement.
