National Healthcare Safety Network (NHSN)
The National Healthcare Safety Network (NHSN) is a Centers for Disease Control and Prevention (CDC) tracking system for healthcare-associated infections. NHSN provides facilities, states, regions, and the nation with data needed to identify problem areas, measure progress of prevention efforts, and ultimately eliminate healthcare-associated infections. NHSN data are analyzed by CDC and others to direct actions for HAI prevention. Local, state and national HAI trends are used to identify emerging problems and areas of concern that need intervention, and to measure progress in HAI reduction against national, state, and local prevention goals.
