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.

HAI Data Uses

Detect Trends

Identify Risk Factors

Guide Treatment

Assess Prevention Impact

Detect Clusters & Outbreaks

Surveillance Data can be Categorized into Process Measures or Outcome Measures

Process Measures

Measures a process that may affect outcomes

Process measures have a 100% target rate and are less complicated because they do not require risk adjustment. These measures apply to a variety of healthcare settings and involve direct care / provider accountability.

Examples: Hand hygiene, Surgical Care Improvement Project (SCIP) measures

Outcome Measures

Measures actual results

Outcome measures have variable goals and often require risk adjustment, making them more complicated. These measures may not be collected in all healthcare settings and may not involve direct care / provider accountability.
