NHSN Metrics

Healthcare facilities collect data on healthcare-associated infections (HAIs) using standardized definitions and may share data with different groups inside (e.g., unit staff, Infection Control Committee) and outside the facility (e.g., Board of Directors, health department, general public). HAI data are used for a variety of purposes, which may include satisfying reporting mandates, comparing infection rates between and within healthcare facilities, providing consumers with information, guiding policies and procedures, evaluating the effectiveness of interventions, and conducting research.
