Description
The National Healthcare Safety Network (NHSN) is a secure, internet-based surveillance system that integrates patient and healthcare personnel safety surveillance systems managed by the Centers for Disease Control and Prevention Division of Healthcare Quality Promotion (CDC, DHQP). NHSN is the nation's most widely used healthcare-associated infection (HAI) tracking system. It provides facilities, states, regions, and the nation with data needed to identify problem areas, measure progress of prevention efforts, and ultimately eliminate HAIs. NHSN allows healthcare facilities to track antibiotic resistant (AR) organisms, antibiotic use, and other adverse events (e.g., blood safety). NHSN is also being used by hospitals and nursing homes to track and report the novel coronavirus (COVID-19) in their facilities, as well as provide indicators of facilities' capacity to meet surges in demand from COVID-19. NHSN fulfills the Centers for Medicare and Medicaid Services (CMS) and state requirements for HAI-AR reporting, and CMS nursing home COVID-19 reporting requirements. CMS also uses CDC's NHSN data and publishes it on the CMS Hospital Compare and Nursing Home compare websites.
Population Covered
NHSN is the nation's most widely used HAI tracking system, collecting data from over 37,000 healthcare facilities in the 50 states, DC, Puerto Rico, US Virginia Islands, American Samoa, Guam, and the Northern Mariana Islands. All American healthcare facilities are eligible for enrollment in NHSN: acute care (including Veterans Affairs and Department of Defense medical centers), long-term acute care hospitals, psychiatric hospitals, and rehabilitation hospitals, outpatient dialysis centers, ambulatory surgery centers, and long-term care facilities and nursing homes. NHSN compiles HAI data reported from over 6,000 hospitals nationwide to compute national acute-care hospital-onset infection measures. Additionally, CDC augmented NHSN to meet the immediate needs of the COVID-19 pandemic. Approximately 3,500 hospitals and almost all 15,400 CMS-certified nursing homes report COVID-19 case and facility capacity data to NHSN.
