*LOS per location is simply calculated as the difference between the End Date/Time and Start Date/Time of stay in that location
* First location:  Start date/time= first location = 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]]
*Depending on the number of locations (''n'') where the patient stayed, we have ''n'' locations and ''n'' start date/time
* Average ICU LOS (in days to 1 decimal place)
**Location 1:  Start date/time= first location start date/time and End Date/time= second location start date/time
* Median ICU LOS (in days to 1 decimal place)

* Total ICU LOS (in days to 1 decimal place)
**Location 3: Start date/time= third location start date/time and End Date/time= fourth location start date/time
===Numerator===
**Location ''n'' (last location): Start date/time= ''n''th  location start date/time and End Date/time= [[Dispo_DtTm]]
For Average ICU LOS, the numerator is Sum of Length of ICU stay of all discharges
*if there is only one location, Start date/time= first location start date/time and End Date/time= [[Dispo_DtTm]]
===Denominator===
For Average ICU LOS, the denominator is Number of discharges

This is what we usually mean when we say Length of Stay; see LOS for other uses.
referred to as the Length of Stay (LOS) per record Before Oct 1, 2020 - a record is defined as an admission in specific Internal Medicine ward or Critical Care Unit as shown in Site_and_Location_table
Starting Oct 1, 2020 - a record for Critical Care, see Definition of a Critical Care Laptop Admission and a record for Internal Medicine, see Definition of a Medicine Laptop Admission.
 
LOS is simply calculated as the difference between the End Date/Time (i.e. Dispo DtTm) and Start Date/Time (i.e. first Service tmp entry) of stay. Start Date and time is defined by either of these fields: Accept DtTm
Arrive DtTm
first Service Start DtTm, see Service_tmp_entry and is the same as the Accept DtTm
 
End Date and time is defined by the Dispo DtTm
 
 
For example:
Start Date/Time: 20 May 2008 11:30
End Date/Time: 21 May 2008 17:45
LOS_Record = 1.260 days
What is actually being reported is the mean and median of this value.

  • Default form:

Patients occupy bed in different locations during the whole stay under the same service for various reasons. LOS per location is simply the difference between the End Date/Time and Start Date/Time of stay in that physical location.


Start Dates of collection

  • Critical Care: July 19, 2018 - started in project "Borrow Arrive" which was moved and continued to project Boarding Loc
  • Medicine: Sept 20, 2019 in project Boarding Loc

None

Frequency

  • Reported when patient had been discharged out of ICU/Medicine.
  • Monthly, quarterly, year based on discharged date of Dispo DtTm

Definition and Derivation

  • LOS per location is simply calculated as the difference between the End Date/Time and Start Date/Time of stay in that location
  • Depending on the number of locations (n) where the patient stayed, we have n locations and n start date/time
    • Location 1: Start date/time= first location start date/time and End Date/time= second location start date/time
    • Location 2: Start date/time= second location start date/time and End Date/time= third location start date/time
    • Location 3: Start date/time= third location start date/time and End Date/time= fourth location start date/time
    • Location n (last location): Start date/time= nth location start date/time and End Date/time= Dispo_DtTm
  • if there is only one location, Start date/time= first location start date/time and End Date/time= Dispo_DtTm
