WOODBURY - A new Consumer Reports study on patient safety in U.S. hospitals ranks Nassau University Medical Center (NUMC) among the five lowest-scoring hospitals in the country. The report also ranks three Long Island hospitals as above-average facilities. Those include St. Francis Hospital in Roslyn, Peconic Bay Medical Center in Riverhead and Glen Cove Hospital. NUMC says that "data indicates significant improvement over the past few years" and notes that it received the Nassau Suffolk Hospital Council's 2011 Excellence in Patient Safety Award for minimizing infections.
