What calculation determines the midnight census in a hospital setting?

The midnight census is calculated to provide a snapshot of patient occupancy in a hospital at a specific moment, typically taken at midnight. The correct calculation involves taking the previous midnight count of patients and adjusting that number based on patient movement within the hospital.

Specifically, this means starting with the count of patients who were present in the hospital at the last midnight, then subtracting the number of patients that were discharged since that time, and adding any new admissions that have occurred. This process accurately reflects the current number of patients in the hospital at midnight.

This method is critical for hospitals as it helps in assessing resource allocation, staffing requirements, and planning for patient care. It provides a more accurate picture than other options which might include factors like just admissions or discharges without considering the overall patient flow and occupancy history.
