The rate is an appropriate measure, but I still struggle with the defintion.
How do you capture all of the cases of VAP. Does an infection control person round with or independant of the ICU team look at the xrays and sputum data? Rely upon staff reporting? has any body used an automated process to screen

I have the same questions. Our IC practitioners want the ICU pulmonologists to do bronch/quantitative lavage on all patients on Vent with PNA, which seems impractical. Have you found out more?

we now are using the CPIS to track our VAP rate, one of its many problems are its poor specificity and who will do it, for now we rely on our fellow to do it on round. we are considering introducing a therapist performed miniBAL.
any experience with those?

VAP per 1000 vent days is not necessarily meaningful; if I have one patient on a vent for a 1000 days I will probably have a 100% VAP rate. If I have 1000 patients on a vent for 1 day, I will have 0% VAP rate. VAP rate will vary depending on patient mix. A better measurement might be, on what day do I have a 50% likelihood of having a VAP (this would have to be calculated). The goal then would be to extend that day out. Any statisticians out there?

What is the most appropriate method to measure ventilator days? Some have recommended screening ICU's at a set time every day or for short time periods. Working in a busy Surgical ICU, I have found that these limited screening periods miss a percentage of ventilated patients. Is it acceptable to use the readily available ventilator billing data to quantify ventilator exposure?

If you are using the CDC definition, they do recommend using a fixed point in time each day to count how many ventilators are in use. It may be best to pick a time of day that does not exclude all the short term vents and is easy to use. While it won't always capture every vent, if you use the same process over time it should normalize out. The link to CDC definitions is
