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 decmimal digit accuracy is used for individual patients, 1 digit for averages)
Note: The number of days for TISS and ITISS can be different than the LOS because the 2 hour rule applies.
