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.
