Mount Sinai South Nassau has earned a 2026 Patient Safety Excellence Award from Healthgrades, ranking it among the nation's top hospitals for patient safety. Only 10 percent of hospitals across the country achieved the ranking.
To determine award recipients, Healthgrades, an independent online platform that aims to help consumers compare health care providers, evaluated risk-adjusted complication and mortality rates from approximately 4,500 hospitals nationwide across 13 patient safety indicators, each representing a serious, preventable complication. Mount Sinai South Nassau came out on top "by preventing infections, medical errors, and other preventable conditions," Healthgrades said. Just 438 hospitals out of nearly 4,500 nationwide that were automatically evaluated by Healthgrades earned the top award.
"This really takes the efforts of everyone in the hospital to achieve, especially our nursing and physician staff," said Alan Wong, DO, Chief Medical Officer and Senior Vice President for Medical Affairs. "And it doesn't happen overnight. We have been working toward this goal for several years now."
Mount Sinai South Nassau's Advisory Board has placed a priority on patient safety for a number of years. "We are very pleased that the efforts of the staff and leadership have paid off," said Joseph Fennessy, a member of the Mount Sinai Health System's Board of Trustees and former Chair of the Board of Directors at Mount Sinai South Nassau. "When you have to go to a hospital-for an emergency or elective procedure-you often have anxiety. Our patients should rest a little easier, knowing that patient safety at Mount Sinai South Nassau is a priority."
Healthgrades' annual analysis revealed significant performance gaps between the nation's highest-and lowest-achieving facilities, making it increasingly important for consumers to seek care at a hospital with top safety ratings. During the 2022-2024 study period, 167,228 preventable safety events occurred among Medicare patients at U.S. hospitals, with four patient safety indicators accounting for nearly 78 percent of all incidents.
According to Healthgrades, patients treated at Mount Sinai South Nassau and other award-winning facilities had a profoundly lower risk of experiencing these leading complications:
The above statistics, which were calculated by Healthgrades' Patient Safety Excellence Award methodology, are based primarily on data from the Agency for Healthcare Research and Quality and the Medicare Provider Analysis and Review file produced by the Centers for Medicare and Medicaid Services, a nationwide dataset of Medicare Part A inpatient hospital and skilled nursing facility stays.
Mount Sinai South Nassau has also received the Healthgrades America's 100 Best Hospitals for Coronary Intervention Award for the third consecutive year. Additionally, it is a recipient of numerous other quality and safety awards, including 10 U.S. News & World Report "High Performing" ratings for chronic obstructive pulmonary disease, colon cancer surgery, diabetes, heart attack, heart failure, hip fracture, kidney failure, pneumonia, maternity, and leukemia, lymphoma, and myeloma.
