Stony Brook University Hospital and Stony Brook Southampton Hospital Once Again Earn ‘A’ in Patient Safety

The Leapfrog Group places Stony Brook among the safest hospitals in the nation.

Stony Brook University Hospital (SBUH) and Stony Brook Southampton Hospital (SBSH) have both earned an ‘A’ Hospital Safety Grade for Spring 2025 from The Leapfrog Group, an independent nonprofit watchdog focused on patient safety.

Leapfrog assigns letter grades to general hospitals across the country based on over 30 performance measures reflecting errors, accidents, injuries and infections, as well as the systems hospitals have in place to prevent them. 

As proud as we are of this recognition and our placement in an elite category of healthcare institutions, we’re even more proud to be a health system where safety isn't just promised – but it's independently verified and consistently delivered.

Earning these 'A' grades from The Leapfrog Group affirms our ongoing commitment to providing safe, high-quality care,” said William A. Wertheim, MD, MBA, 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, MS, FACHE, CPHQ, 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 is Stony Brook University Hospital’s second “A” and Stony Brook Southampton Hospital’s third sequential safety A grade making it one of only 16 hospitals in New York State to achieve three consecutive ‘As.’

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, 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 Medicine, its leadership, clinicians, staff and volunteers for creating a culture where patients come first.”

The Leapfrog Hospital Safety Grade stands as the only hospital ratings program focused solely on preventable medical errors, infections and injuries that kill more than 500 patients a day in the United States. This program is peer-reviewed, fully transparent and free to the public. Grades are updated twice annually, in the fall and spring.
