Definition and Derivation

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

Numerator

Formula

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

Example

• 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 %
