Yes. The repeat infection timeframe (RIT) is set by the date of event (DOE).  For surveillance purposes a POA infection may only have a DOE on the day of admission or the next day. If the first element within the infection window period (IWP) occurred in the 2 days before admission, the DOE is considered the day of admission. The RIT is the 14-day time period where no new infections of the same type are reported, beginning with the date of event. Example: A UTI with E. coli identified with DOE on the day of admission is considered POA. If 10 days later a new urine culture shows K. pneumonia >100,000 CFU/ml, then the organism is added to the original UTI (no new event is cited but rather is considered a continuation of the original event). The UTI RIT remains Hospital Days 1-14. NOTE:  If a patient is admitted with a POA BSI and subsequent blood specimens are collected, the POA BSI must be identified as either primary or secondary in nature.  A primary POA BSI will set a BSI RIT.  However, a POA BSI that is secondary to another site of infection will NOT set a BSI RIT.  It will only set an RIT for the type of infection to which the BSI is secondary.
