Does the Specific Time of Day Used to Capture Data on Ventilator-Days Have an Impact on the Documented Rates of Ventilator-Associated Pneumonia?

  • Thomas R. Talbot (a1) (a2) and John M. Starmer (a3)

Abstract

Definitions of ventilator-associated pneumonia do not note a preferred daily time for obtaining denominator data. We examined collecting data on the number of ventilator-days at different times of day in 7 intensive care units. Rates of ventilator-associated pneumonia did not significantly differ when denominator data were collected at midnight, 8 AM, or 4 PM, supporting standard definitions.
