Definition and Derivation

The proportion of patients discharged to the ward or step-down where discharge occurred between 22:00 and 06:59


Num = Number of survived discharges to ward that occurred between 22:00 and 06:59


Denom = Number of survived discharges to ward


Night Time Discharge Rate (%) = Num / Denom * 100


  • Time Reference: Discharge Dates from Jan 1, 2017 to March 31, 2017
  • Total survived discharges to ward that occurred between 22:00 and 06:59 = 21
  • Total survived discharges to ward = 102
  • Night Time Discharge Rate(%) = 21 / 102 * 100= 20.6 %
