National Nosocomial Infections Surveillance (NNIS) Report, Data Summary from October 1986-April 1996, Issued May 1996

摘要

This report is a summary of the data collected by participating hospitals in the National Nosocomial Infections Surveillance (NNIS) System from October 1986 through April 1996 and updates previously published data. The NNIS System was established in 1970 when selected hospitals in the United States routinely began reporting their nosocomial infection surveillance data for aggregation into a national database. Hospitals participating in the NNIS System provide general medical-surgical inpa-tient services to adults or children requiring acute care. Identity of the 231 hospitals currently participating in NNIS hospitals is confidential. All NNIS data are collected by use of four standardized protocols, called surveillance components: hospital-wide (the only component until October 1986), adult and pediatric intensive care unit (ICU), high-risk nursery (HRN), and surgical patient. The components may be used singly or simultaneously, but once selected, they must be used for a minimum of 1 calendar month. All infections are categorized into major and specific infection sites by use of standard Centers for Disease Control and Prevention (CDC) definitions that include laboratory and clinical criteria.
