Bed occupancy is usually used in aggregate form as "per location" and/or "per timeframe", e.g. by day/month/quarter/year x Ward/Unit x Hospital.

Occupancy Calculation

If admit date the same as discharge date - calculate the difference between the discharge time and admit time.
if admit date is not the same as disch date
- for first date - calculate the difference between 2400 and admit time
- for in between date - consider 1 full day
- for last date - calculate the difference between Dispo DtTm - 001
Bed Occupancy per day = sum of bed occupied by all patients in a given day

This is being done by defining a counter for people admitted and discharged to an ICU. The counter is a -1 or +1. The Admit date/time is used as the time to +1 to census. The discharge date/time is used as the time to -1 to census. On a chronological order of time, the patient admitted is added and the patient discharged is subtracted based on time per day.
Per day, the minimum and maximum census are used to calculate the daily bed occupancy as follows:
Bed occupancy per day = (Minimum + Maximum)/2

This means for a given hour of the day, how many beds are occupied.
This is done by adding the patient admitted and subtracting the patient discharged based on time per day as in Definition2 above.
Bed Occupancy per day at ##Hour = number of patients occupying a bed at ##Hour.
