TRENTON New Jersey’s 82 acute care hospitals top the nation in delivering high-quality care for several conditions, according to a state analysis of federal data. The data covers treatment of patients with pneumonia, heart failure and heart attack, as well as prevention of surgical wound infections, between April 2004 and March. About 4,200 U.S. hospitals report data on treatment for those conditions and 16 other areas to the federal Centers for Medicare and Medicaid Services. The New Jersey Department of Health and Senior Services examined that data, which is compiled on a Web site called Hospital Compare. New Jersey scored 86 out of 100 on how often hospitals provided proven treatments to patients in the four categories and tried to prevent further problems, by doing things such as signing up heart patients for smoking cessation counseling. South Dakota, Iowa, Maine and New Hampshire followed New Jersey in the top five. “New Jersey’s statewide focus on high-quality care is making a difference,” health Commissioner Dr. Fred M. Jacobs said in a statement. The state analysis found three New Jersey hospitals or systems were among the country’s top nine: Hackensack University Medical Center, Robert Wood Johnson University Hospital in New Brunswick and Atlanticare Regional Medical Center, with hospitals in Atlantic City and Pomona. “This is important and welcome news for the 17 million inpatients and outpatients who seek care at our hospitals each year,” New Jersey Hospital Association President Gary Carter said in a statement.
