What denominator data are collected for the Patient Safety component (PSC)?
For the Device-associated (DA) module of the PSC, both the number of patient-days and the number of device-days are collected for the location and device being monitored. These data are also referred to as Summary Data. For example, if ventilator-associated pneumonias are monitored in the surgical ICU, then the number of patient-days and ventilator-days are reported for that unit. You will choose the DA infections and locations to be monitored each month. For the Procedure-associated (PA) module of the PSC, a denominator record is generated for each patient undergoing the operation selected for monitoring during the month. For the Antibiotic Use and Resistance (AUR) option, in the Microbiology section, the number of isolates of each tested organism is recorded. Additionally, for each organism tested, the number of isolates demonstrating sensitivity (S) intermediate sensitivity (I), resistance (R) or not tested (N) is recorded. These data are collected separately for each ICU, all inpat
