Mather Hospital earns 18th Leapfrog “A” for patient safety

Eight Northwell hospitals across the region recognized by the national nonprofit Leapfrog Group, demonstrating the health system’s commitment to patient safety.

PORT JEFFERSON, NY – Mather Hospital received its 18th top “A” Hospital Safety Grade from The Leapfrog Group for its achievements in protecting hospital patients from preventable harm and errors.

“I congratulate all our team members for this acknowledgement of Mather Hospital’s commitment to patient safety and nursing excellence,” said Executive Director Kevin McGeachy. “We work together across departments to ensure a culture of safety.”

Mather was one of eight Northwell Health hospitals to earn an “A” grade for patient safety, according to a report released today by the Leapfrog Group. The others are Huntington Hospital; Long Island Jewish; Forest Hills, North Shore University Hospital, Manhasset; Northern Westchester Hospital, Mt. Kisco; Peconic Bay Medical Center, Riverhead; South Shore University Hospital, Bay Shore; and Syosset Hospital.

“The spring Leapfrog report shows that Northwell hospitals across the region are continuing to provide the best quality and safest care to our patients at both our community and tertiary care hospitals,” said Peter Silver, MD, senior vice president, associate chief medical officer and chief quality officer at Northwell Health. “The survey reflects our deep commitment to patient safety across the care continuum,. Our scores reflect not only our dedication to providing the best possible patient care, but how we strive to do better every day.”

The Leapfrog Group, a national nonprofit organization, assigns an A, B, C, D or F grade to nearly 3,000 acute-care hospitals nationwide, which is based on 30 evidence-based patient safety performance measures. The organization issues the report twice annually.

Dr. Silver said the Leapfrog survey reviews key patient safety measures including hospital-acquired infections, medication safety, hand washing, maternity care, and surgical safety. Certain patient experience scores also are factored in the analysis, which are based on patient satisfaction surveys administered by Press Ganey Associates.

We are extremely proud of the accomplishments of all our hospitals and our 83,000 team members who go above and beyond every day to improve care for our patients who entrust us with their care,” said Dr. Silver. “Northwell has a culture for continuous improvement, and you feel that when you walk into our buildings.”
