How is Adjusted Occupied Bed (AOB) calculated?

• A. AOB = Average Inpatient Census + Adjustment for Outpatient Activity.
• B. AOB = Average Inpatient Census - Outpatient Activity
• C. AOB = Total patient-days / days in period
• D. AOB = Occupied beds + Outpatient Activity

Answer: (A)

Adjusted Occupied Beds capture bed demand by combining the actual inpatient census with an adjustment for outpatient activity that uses beds but isn’t counted as inpatients. The Average Inpatient Census represents the typical number of beds occupied by inpatients each day. The Adjustment for Outpatient Activity accounts for beds used by observation, same-day procedures, or other outpatient care that still tie up a bed, even though the patient isn’t classified as an inpatient. By adding these together, you get a measurement of bed occupancy pressure that reflects both inpatient and outpatient bed use. So, the best approach is to add the average inpatient census to the outpatient adjustment: AOB = Average Inpatient Census + Adjustment for Outpatient Activity. For example, if the average inpatient census is 90 beds and outpatient activity contributes an adjustment of 5 beds, the AOB would be 95. The other concepts don’t fit because subtracting outpatient activity would understate bed demand, using total patient-days over days in the period yields the standard average daily census rather than an adjusted occupancy measure, and simply adding outpatient activity to occupied beds can misrepresent how the measure is defined and used for capacity planning.
