NAPH Members Perform Well on CMS Core Measures(June 2007) As part of its ongoing commitment to quality improvement, NAPH has been analyzing member-versus-national hospital performance on the 21 key measures that the federal Centers for Medicare and Medicaid Services (CMS) is using in its Medicare "pay-for-reporting" effort. These measures cover four clinical conditions: heart attack, heart failure, pneumonia, and surgical care infection prevention. NAPH’s analysis concludes that its members score well across the board, particularly on CMS's cardiovascular measures.
