**Starting Oct 1, 2020, the above TISS28 element is collected as part of the CCI Collection but not at 2300HR , before this they were part of TISS28 Data.mdb. The presence of Vent at 2300 hour is imputed or assigned by inference using this method - if patient is present at 23HR and the [[TISS28]] element {{TISS w Nr | Invasive Mechanical Ventilation (TISS Item)}}  is marked, then the patient is assumed to have ventilator at 2300 hour.

**Jan 2013 to Sept 2020 - Daily data for Invasive are taken on [[TISS28]] element {{TISS w Nr | Invasive mechanical ventilation at 2300 hrs (TISS Item)}}.  The TISS form is being marked daily by ICU bed side nurses and quality checked by the Database Data Collectors.
* Aug 2009 to Dec 2018, the dates when VAP occurred were taken from the Tmp project [[QA Infection]].

Reported as

Number of cases of #VAP per 1000 Ventilator-days

Significance

  • #VAP is a device-associated infection, the device being the artificial airway-ventilator-circuit system. #VAP is associated with worse patient outcomes and higher costs.
  • Factors affecting the incidence of #VAP include those from patients (severity of illness, comorbidities, etc.) and processes of care.
  • #VAP rate is a measure of the incidence of #VAP.

Sampling Plan / Procedure

Inclusion Criteria

  • 100% sampling for all patients on invasive mechanical ventilation as indicated by presence of #Ventilator Days at 23 HR
  • 100% sampling for all cases with VAP incidence following the criteria listed in #VAP

Exclusion Criteria

Exclude non-invasive ventilation.

Frequency

  • Recording the date the #VAP occurred.
  • Daily recording of dates of patient being on invasive mechanical ventilation at 2300 HR
  • Total number of ventilated days are calculated and reported on a monthly, quarterly or yearly basis based on the daily data.
  • Time Reference is calendar month, quarter or year.

Definition and Derivation

Numerator

Num = Total #VAP Cases in a calendar period

Denominator

Denom =Total Vent Days on the same period as the numerator

Formula

VAP Rate = Num / Denom * 1000

Example

  • Time Reference: Calendar Dates from Jan 1, 2017 to March 31, 2017
  • Total VAP cases = 5
  • Total days patients are on invasive ventilator at 2300 HR = 688
  • VAP Rate per 1000 days = (5 / 688) * 1000 = 7.3%

Data Sources
