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 in the count of readmission.
  • Elective surgery
    • Admit Type for APACHE II is not 'Elect.Surg'
  • Palliative in this context means at least one of the following is present:
    • based on ICD10 Palliative care where available
    • tmp Comfort Care

Definition and Derivation

• Cargo

• Categories

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

Numerator

• Num1 = Number of ICU readmission within 72 hours coming from ward
• Num2 = Number of ICU readmission within 72 hours coming from ward, home or elsewhere

Denominator

• Denom1 =Total Number of discharges who went to ward
• Denom2 =Total Number of discharges who went to 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 coming from ward= 5
• Total discharges who went to ward = 102
• Readmission Rate(%) = 5 / 102 * 100= 4.9 %
