NHSN consists of several modules, each designed to monitor specific types of infections and adverse events. Key modules include:
1. Patient Safety Component: Focuses on HAIs, such as central line-associated bloodstream infections (CLABSIs), catheter-associated urinary tract infections (CAUTIs), and surgical site infections (SSIs). 2. Healthcare Personnel Safety Component: Monitors occupational exposures, such as needlesticks and other sharps injuries, and tracks healthcare personnel immunization rates. 3. Biovigilance Component: Tracks adverse events related to blood transfusions. 4. Outpatient Procedure Component: Monitors infections and other adverse events in outpatient settings.
