Significance

Ventilation duration can be considered a surrogate marker of interrelated factors such as : ICU patients characteristics (acuity, comorbidity, premorbid functional status), structural and process-related aspects of ICU care (staffing ratios, staff expertise, processes for effective ventilator). This is related to QA Infection VAP.

Sampling Plan / Procedure

Inclusion Criteria

100% sampling for all patients on mechanical ventilation. Mechanical ventilation includes:

• Invasive Mechanical Ventilation via ET Tube or tracheostomy
• Non-invasive CPAP or BIPAP

Exclusion Criteria

Patients who are not of mechanical ventilation

Frequency

• Daily recording of dates a patient being on mechanical ventilation
• Total number of ICU patients and ICU days being on mechanical ventilation are calculated and reported on a monthly, quarterly or yearly basis based on the daily data.

Definition and Derivation

Numerator

Total Mechanical Vent Days in a given period

Denominator

Number of ventilated patients on the same period as the numerator

Data Sources

Daily data for Invasive and non invasive mechanical ventilation are taken on TISS elements #18 and #21 respectively. The TISS form are marked daily by ICU bed side nurses and quality checked by the Database Data Collectors.
