  • Efficient

Reported as

Ventilation days / Total Patient days in percent (%)

Significance

VUR is a surrogate marker of multiple interrelated factors: ICU patients characteristics (acuity, comorbidity, premorbid functional status), structural and process-related aspects of ICU care (staffing ratios, staff expertise, processes for effective ventilator), hospital factors (presence of step-down unit, factors affecting patient flow).

Sampling Plan / Procedure

Inclusion Criteria

Exclusion Criteria

  • Exclude non-invasive ventilation.

Frequency

  • Daily occupancy of patients who stayed in ICU
  • Daily recording of dates of patient being on invasive mechanical ventilation
  • Total occupancy in terms of patient days are calculated and reported on a monthly, quarterly or yearly basis based on the daily data.
  • 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 Invasive Mechanical Vent Days in a calendar period

Denominator

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

Formula

VUR = Num / Denom * 100

Example

  • Time Reference: Calendar Dates from Jan 1, 2017 to March 31, 2017
  • Total days patients are on invasive ventilator = 830
  • Total patient days from Jan 1, 2017 to March 31, 2017 at HSC MICU = 1103.7
  • VUR (%) = 830 / 1103.7 = 75.2%
