* Once the transfer ready 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 a proxy time of 10:00 am for day shift and midnight for night shift will be used for calculation purposes. 
**If more than one transfer ready has been written, use the transfer ready date & time closest to actual ICU transfer
* 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 (e.g. stable enough to transfer) to date/time transfer out of ICU (in hours) less 4.0 hours (and divided by 24 to give yield total avoidable days)
Number of ICU readmission within 72 hours per 100 discharges to ward

Percent of total discharges to ward

Significance

Unplanned readmissions are associated with worse patient outcomes. Most factors associated with an increased risk of readmission are patient and admission-specific. System related risk factors include discharge at night and ICU occupancy at the time of discharge. Readmission may reflect premature transfer out of ICU due to errors in clinical judgment or system constraints.

Definition and Derivation

Number of ICU readmission within 72 hours per 100 discharges to ward

Numerator

Num = Number of ICU readmission within 72 hours coming from ward

Denominator

Denom =Total Number of discharges who went to ward

Formula

Readmission Rate(%) = Num / Denom * 100

Example

  • Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
  • Total readmission within 72 hours coming from ward=
  • Total discharges who went to ward =
  • Readmission Rate(%) (%) = 254.5 / 1175.3 * 100= 21.7%
