Significance

Avoidable days reflects the amount of time that patients occupy an ICU bed when the patient no longer requires the intensity of care provided in an ICU setting. It can identify and quantify issues around flow out of the ICU.

Sampling Plan / Procedure

Inclusion Criteria

100% of all patients physically present in an ICU bed awaiting transfer out of the ICU and having a date value on the Transfer Ready DtTm field

  • For the Critical Care Report, the Directors and QIT agreed to separate the transfer to IICU from the rest of the locations (to home, to ward, to outside hospital ward, rehab, PCH and those who died but have transfer ready date_time) - start date Jan to March 2018 Qtr report.

Exclusion Criteria

Frequency

  • Once the transfer ready date has been written and the allowable 4.0 hours has elapsed, compute Transfer Delay or the total time it takes for ICU patient to leave the unit.
    • If no time is indicated with the transfer ready date_tm field a proxy time of 10:00 am for day shift and midnight for night shift will be used for calculation purposes.
  • To be completed at time of discharge from ICU, compute the total days spent in ICU (refer as LOS)
  • To be calculated and reported on a monthly, quarterly or yearly basis based on either ICU Admission Dates or ICU Discharge Dates.
  • For the Director reports, the discharge dates are used as the time of reference.

Definition and Derivation

Avoidable days is defined as the total time from date/time of transfer ready to date/time transfer out of ICU (in hours) less 2.0 hours (and divided by 24 to give yield total avoidable days)

Numerator

Num = Total Transfer Delay in a given period

Denominator

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

Formula

Avoidable Days (%) = Num / Denom * 100

Example

  • Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
  • Total Avoidable Days of all patients with transfer ready date-time= 254.5
  • Total LOS of all ICU discharges = 1175.3
  • Avoidable Days (%) = 254.5 / 1175.3 * 100= 21.7%
