Reported as

  • Definition1 : Percent of total discharges to ward
  • Definition2 : Percent of total discharges to ward, home and elsewhere

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.

Sampling Plan / Procedure

Inclusion Criteria

We report these in two ways:

  • Definition1: 100% of all ICU patients discharged to ward
  • Definition2: 100% of all ICU patients discharged to ward, home or elsewhere

Exclusion Criteria

  • Definition1 & 2 : Excluding patients with planned and scheduled surgery in the count of readmission.
  • Definition2 : Excluding patients who left AMA or palliative patients in the count of readmission.

Frequency

Monthly, quarterly or yearly based on either admission dates or discharge dates

Definition and Derivation

Readmission means the patient left/discharged out of ICU to elsewhere and came back to ICU in the same or different facility from elsewhere. Readmission count is accounted to the unit discharging the patient the first time and not to the unit admitting the patient the second time.

  • Definition1 : Number of ICU readmission within 72 hours per 100 discharges to any ward
  • Definition2 : Number of ICU readmission within 72 hours per 100 discharges to any ward, home or elsewhere

Numerator

  • Num1 = Number of ICU patients discharged to any ward and readmitted to any ICU within 72 hours coming from elsewhere
  • Num2 = Number of ICU patients discharged to any ward, home or elsewhere and readmitted to any ICU within 72 hours coming from elsewhere

Denominator

  • Denom1 =Total Number of discharges who went to any ward
  • Denom2 =Total Number of discharges who went to any ward, home or elsewhere

Formula

Readmission Rate(%) = Num / Denom * 100

Example

  • Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
  • Total readmission within 72 hours of patients previously discharged to any ward= 5
  • Total discharges who went to ward = 102
  • Readmission Rate(%) = 5 / 102 * 100= 4.9 %
