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).
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 on 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.
- Time Reference for month, quarter or year can be based on ICU admission dates or ICU discharge dates. For the Director reports, the discharge dates are used as the time of reference.
Definition and Derivation
Numerator
Num = Total Mechanical Vent Days in a given period
Denominator
Denom =Number of ventilated patients on the same period as the numerator
Formula
Duration of Mechanical Ventilation in days = Num / Denom
Example
- Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
- Number of patients who have discharge dates from Jan 1, 2017 to March 31, 2017 and who were on mechanical ventilation at HSC MICU = 158
- Total Days these patients are on mechanical ventilation (invasive and/or non-invasive) = 981
- (if a patient had both Invasive and non-invasive Mechanical ventilation in a day, this is counted as one day only.)
- Duration of Mechanical Ventilation in days = 981 / 158 = 6.2 days
Data Sources
Prior Jan 2013, daily data for Invasive and non invasive mechanical ventilation are taken from the following TISS76-Legacy elements
- T29 A/C, SIMV, PSV with intermittent or continuous muscle relaxant/sedation. See: TISS76-Legacy
- T30 A/C, SIMV, PSV without muscle relaxant/sedation. See: TISS76-Legacy
- T31 Spontaneous CPAP or BIPAP
The TISS form is being marked daily for the first 10 days by ICU bed side nurses and quality checked by the Database Data Collectors. For LOS > 10, if any of the above TISS item is marked on the 10th day, assume that the item is being marked until one day before discharge date.
Jan 2013 to Sept 2020, daily data for Invasive and non invasive mechanical ventilation are taken from the following TISS28 elements
The TISS form is being marked daily by ICU bed side nurses and quality checked by the Database Data Collectors.
Starting Oct 1, 2020, the above TISS28 elements are collected as part of the CCI Collection, before this they were part of TISS28 Data.mdb.
