Bed Occupancy Rate Calculation
Calculate the hospital bed occupancy rate (bed occupancy rate) using occupied bed days, number of beds, and number of days. Formula, interpretation, and scientific basis.
Bed occupancy rate
86,7%
Generally, a range of 75–85% is considered efficient and safe; very high values may indicate capacity pressure, while very low values may indicate idle capacity.

Scientific and theoretical basis
Bed occupancy rate (bed occupancy rate, BOR) is a fundamental capacity and efficiency indicator that shows how much of the available bed capacity is utilized in a healthcare institution during a specific period.
Formula and Logic
The rate is found by dividing the number of occupied bed days (patient days) by the available bed days capacity during the period:
Bed Occupancy Rate (%) = Occupied Bed Days / (Number of Beds × Number of Days) × 100
The denominator represents the total bed days that could theoretically be provided during the period. The numerator is the actual bed days used.
How is it interpreted?
Very high occupancy (e.g., above 90%) can lead to issues finding space for emergency admissions, difficulties in infection control, and increased staff burden. Very low occupancy indicates idle capacity and cost inefficiency. In the literature, a sustainable target is often considered to be in the 75–85% range; however, the ideal range varies by specialty (e.g., intensive care, maternity) and institution.
Considerations
The indicator should not be interpreted alone; it should be evaluated together with average length of stay and bed turnover rate. Data quality (accuracy of admission-discharge records) directly affects the result; therefore, consistent records through HBYS are important.
Sık Sorulan Sorular
How is the bed occupancy rate calculated?
Occupied bed days are divided by the product of the number of beds and the number of days, then multiplied by 100: Occupied Bed Days / (Number of Beds × Number of Days) × 100.
What is the ideal bed occupancy rate?
A range of 75–85% is often considered sustainable; however, the ideal value varies by specialty and institution.
