Ventilator Utilization Ratio
Ventilator Utilization Ratio (VUR) is proportion of ICU days being spent on invasive mechanical ventilation.
|Indicator:||Ventilator Utilization Ratio (VUR)|
|Start Date:||Jan 1 2013|
Ventilation days / Total Patient days in percent (%)
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
- 100% sampling for all patients on invasive mechanical ventilation as indicated by the presence of Invasive Mechanical Ventilation (TISS Item)
- 100% sampling for all patients in ICU.
- Exclude non-invasive ventilation.
- 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
Num = Total Invasive Mechanical Vent Days in a calendar period
Denom =Total Patient Days on the same period as the numerator
VUR = Num / Denom * 100
- 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%
- Daily data for Invasive are taken on TISS28 element Invasive Mechanical Ventilation (TISS Item). The TISS form is being marked daily by ICU bed side nurses and quality checked by the Database Data Collectors.
- Daily occupancy per day are derived from Accept DtTm or Arrive DtTm and Dispo DtTm.
