LOS

See: Length of stay under Indicator Definitions.

For our purposes, LOS (length of stay) is the combined number of days a patient spent on units on which we collect data. It is not the amount of time spent in the hospital as we don't have access to hospital admit/discharge data. Ward LOS and ICU LOS are included in our monthly, quarterly and annual reports.

• LOS = Discharge Date/Time – Admit Date/Time.

For example:

• Admit Date/Time: 20 May 2008 11:30
• Discharge Date/Time: 21 May 2008 17:45
• LOS = 1.260 (3 decimal digit accuracy is used for individual patients, 1 digit for averages)

LOS vs TISS LOS

The number of days for TISS (ICU) can be different than the LOS because the TISS76-2 hour rule applies.

For TISS28 LOS is the same as the regular LOS described above.

No longer excluding short LOS resuscitation patients
