100% sampling of patients on mechanical ventilation as indicated by the presence of one of the following TISS items:

* Daily recording of dates of patient being on mechanical ventilation.
* Same as [[Duration of Mechanical Ventilation]]
* Total number of ICU discharges being on mechanical ventilation at least one day during the ICU stay are counted.
* The number of beds opened per unit is taken from the [[Bed Census]] Database.
* Time Reference for month, quarter or year is based on  ICU discharge dates.
* Number of physical ICU beds available. The number of available bed rarely change except for pandemic or seasonal closures.
** If the number of daily available bed changes over the period of time, use the number of bed which is the most numbered. Example, in a monthly period,  20 out of 30 days have opened bed = 15 while 10 days have 14 beds, use the number of bed=15.

Daily data for Invasive and non invasive mechanical ventilation are taken on [[TISS28]] elements {{TISS w Nr | Invasive Mechanical Ventilation (TISS Item)}} and {{TISS w Nr | Non-invasive CPAP or BIPAP (TISS Item)}} respectively.  The TISS form is being marked daily by ICU bed side nurses and quality checked by the Database Data Collectors.

Starting Oct 1, 2020, these [[TISS28]] elements are collected and entered as CCI procedures by the Database Data Collectors.

The daily bed available or opened per unit is taken from the Bed Census Database.

Ventilated Patient Flow is the number of mechanically ventilated patients at any time during the ICU stay per bed per period of time.

Reported as

Count of patients on mechanical ventilation per bed per time frame

Significance

Experience with mechanical ventilation is associated with improved patient outcomes. Factors affecting ventilated patient flow include ICU patient type and acuity, Structural and process-related aspects of care, and factors affecting patient flow following ICU care.

Sampling Plan / Procedure

Inclusion Criteria

Same as Duration of Mechanical Ventilation

Exclusion Criteria

Same as Duration of Mechanical Ventilation

Frequency

Definition and Derivation

Numerator

Num = Total number of discharges who were mechanically ventilated at any time during the ICU stay

Denominator

Denom = Number of ICU beds

Formula

Ventilated Patient Flow = 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
  • Opened Bed = 15
  • Ventilated Patient Flow = 158 / 15 = 10.5
