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 ward occupancy at the time of discharge. Readmission may reflect premature transfer out of hospital due to errors in clinical judgment or system constraints.

Sampling Plan / Procedure

Inclusion Criteria

100% of all patients discharged from medicine ward to home/PCH, outside Winnipeg/Manitoba/Canada hospitals/facilities.

Exclusion Criteria

Excluding patients who left against medical advice (AMA), palliative patients in the count of readmission.

Exclusions for readmissions are the following:

  • There is a planned admission like elective surgery
  • Left the ward or unit against medical advice (Dispo = AMA)
  • Palliative patients at admission
    • The coding for Palliative changed over time.
  • HSC IICU has no readmission

Frequency

Definition and Derivation

For medicine, a readmission is a patient where

  • (current admit date/time) - (most recent discharge date/time to the hospital) is within 7 days after their most recent discharge date time to the hospital
  • is admitted from outside hospital

Numerator

Num = Number of ward readmission within 7 days after being discharged out

Denominator

Denom =Total Number of discharges who left the hospital (e.g. went home/nursing home, outside city, province or country)

Formula

Readmission Rate(%) = Num / Denom * 100

Example

  • Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
  • Total readmission within 7 days after discharge to hospital= 5
  • Total discharges who left the hospital= 102
  • Readmission Rate(%) = 5 / 102 * 100= 4.9 %
