Definitions:
Present on Admission (POA): Infections that are POA, as defined in Chapter
2, are not considered HAIs and therefore are never reported to NHSN.
Healthcare-associated infections (HAI): All NHSN site specific infections
must first meet the HAI definition as defined in Chapter 2 before a site
specific infection (., CAUTI) can be reported to NHSN.
Urinary tract infections (UTI) are defined using Symptomatic Urinary Tract Infection (SUTI) criteria, Asymptomatic Bacteremic UTI (ABUTI), or Urinary System Infection (USI) criteria (See Table 1 and Figure 3).
Date of event (DOE): For a UTI, the date of event is the date when the first element used to meet the UTI infection criterion occurred for the first time within the 7-day Infection Window Period. See definition of Infection Window Period in Chapter 2 .
Synonyms: infection date, event date.

These devices are also called Foley catheters. Condom or straight in-and-out catheters are not included nor are nephrostomy tubes, ileoconduits, or suprapubic catheters unless a Foley catheter is also present. Indwelling urethral catheters that are used for intermittent or continuous irrigation are included in CAUTI surveillance.
Catheter-associated UTI (CAUTI): A UTI where an indwelling urinary catheter was in place for >2 calendar days on the date of event, with day of device placement being Day 1, AND
an indwelling urinary catheter was in place on the date of event or the day before. If an indwelling urinary catheter was in place for > 2 calendar days and then removed, the date of event for the UTI must be the day of discontinuation or the next day for the UTI to be catheter-
