Stony Brook University Hospital and Stony Brook Southampton Hospital have each earned an "A" Hospital Safety Grade for Spring 2025 from The Leapfrog Group, an independent national nonprofit watchdog focused on patient safety. The organization's grading system evaluates hospitals based on more than 30 performance measures including errors, accidents, injuries, and infections, as well as the systems in place to prevent them.

"Earning these 'A' grades from The Leapfrog Group affirms our ongoing commitment to providing safe, high-quality care," said William A. Wertheim, MD, executive vice president for Stony Brook Medicine. "This achievement is a testament to the dedication of our entire healthcare team, who work tirelessly to ensure our patients receive outstanding care in the safest environment possible."

"This top mark is a reflection of how deeply every member of the Stony Brook team cares about our patients," said Carol Gomes, chief executive officer of Stony Brook University Hospital. "Every day, they go the extra mile to keep those in our community safe. It means trusted, exceptional care is always close to home — delivered by people who truly put the patient’s well-being first."

This achievement is Stony Brook University Hospital's second "A" grade, and Stony Brook Southampton Hospital has received its third consecutive "A", making it one of only 16 hospitals in New York State to achieve three consecutive "A" grades.

"We are honored to have again earned the nation's top distinction for patient safety, an 'A' from the Leapfrog Hospital Safety Grade," said Emily Mastaler, chief administrative officer at Stony Brook Southampton Hospital. "This spring 'A' grade, follows our fall and spring 2024 'As', and represents the dedication of every one of our team members, who work 24/7, year-round, to ensure our patients’ safety."

"Achieving an 'A' Hospital Safety Grade reflects enormous dedication to patient safety," said Leah Binder, president and CEO of The Leapfrog Group. "I extend my congratulations to Stony Brook University Hospital and Stony Brook Southampton Hospital for creating a culture where patients come first."

The Leapfrog Hospital Safety Grade is the only program that focuses solely on preventable medical errors, infections, and injuries. These errors are responsible for over 500 patient deaths daily in the United States. The program is peer-reviewed, fully transparent, and available to the public. Grades are updated semiannually.
