Impact of changes in the NHSN catheter-associated urinary tract infection (CAUTI) surveillance criteria on the frequency and epidemiology of CAUTI in intensive care units (ICUs).

The impact of the 2013 NHSN CAUTI definition on CAUTI rates was analyzed. A total of 107 CAUTI episodes were identified; 60 according to NHSN 2013 definitions only and 47 according to the 2012 and 2013 definitions. Physician-diagnosed "other infections" were more common among patients who had CAUTI only according to NHSN 2013 definitions (P<.001).
