HAI prevention - National Healthcare Safety Network (NHSN)

Healthcare-associated infections (HAIs)

"HAI" logo

NHSN (Exit DHS) is a national HAI database used by healthcare providers to report surveillance data using standardized definitions. DPH encourages Wisconsin providers to use NHSN to enhance statewide surveillance. Aggregate state data are available in the DPH annual HAI report (PDF, 120 KB).

NHSN is also the HAI surveillance method used by federal public reporting programs. Hospital-specific data are available on the Wisconsin Hospital Association (WHA) CheckPoint® (Exit DHS) and the Centers for Medicare & Medicaid Services (CMS) Hospital Compare (Exit DHS) websites.

These worksheets were developed to provide hospitals and nursing homes with a checklist for working through potential HAI cases using the NHSN definitions. The Long-term Care Facility (LTCF) rate tracker incorporates NHSN definitions for easy rate calculation and graphing.
