Significance

Length of stay (LOS) is an important measure for utilization purposes and is frequently used as a measure of ICU resource use. LOS is influenced by many factors but safe and effective critical care should result in a shorter ICU length of stay.

Sampling Plan / Procedure

All ICU admissions - see Definition of a Critical Care Laptop Admission .

If transfers occur within ICU’s within the same facility eg. MICU, SICU and IICU, this will be reported as 3 individual length of stays and not one cumulative LOS.

Inclusion Criteria

Include all admissions to ICU being taken care by the same service wherever the patients are physically present (in a bed in the unit or in a borrowed bed in another location). See Definition of a Critical Care Laptop Admission for further information about which patients are included.

Exclusion Criteria

None

Frequency

• Reported when patient had been discharged out of ICU.
• Reported on a monthly or quarterly basis as an average and median value
• Reported as total value when used as denominator in the calculation of other indicators.

Definition and Derivation

• ICU LOS = ICU discharge date/time – ICU admit date/time (expressed in days) where ICU discharge date/time = Dispo_DtTm and ICU admit date/time = Admit DtTm
• Average ICU LOS (in days to 1 decimal place)
• Median ICU LOS (in days to 1 decimal place)
• Total ICU LOS (in days to 1 decimal place)

Numerator

For Average ICU LOS, the numerator is Sum of Length of ICU stay of all discharges

Denominator

For Average ICU LOS, the denominator is Number of discharges

Data Sources

• Admit DtTm and Dispo DtTm
• Can also be taken from the Created_Variables_CC 2021 table of CFE
