Used in aggregate form as "per location" and/or "per timeframe", e.g. by month/quarter/year x Ward/Unit x Hospital
QI domain
- 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
- 100% sampling for all patients on invasive mechanical ventilation as indicated by the presence of T18 - Invasive Mechanical Ventilation (TISS Item)
- 100% sampling for all patients in ICU.
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 any time
- 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%
Data Sources
- Daily data for Invasive are taken on TISS28 element T18 - 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. Starting Oct 1, 2020, this TISS28 element is collected and entered as CCI procedures by the Database Data Collectors.
- Daily occupancy per day are derived from Admit DtTm and Dispo DtTm.
