A management engineering study determines that the average procedure time is 47 minutes… hospital replaced scheduling system. Which source of data was used?

A hospital census provides information on the number of patients and their demographics within the facility. While this data is essential for understanding hospital capacity and patient flow, it does not directly relate to the time taken for procedures and therefore cannot be the source referenced in the study.

The number of physicians indicates staffing levels and potential availability for patient care. However, this data does not reflect the average duration of procedures themselves, which is critical to determining scheduling efficiency. Hence, it cannot be the source of data utilized in this context.

Nursing staff coverage pertains to the availability of nurses to assist with patient care and procedures. While important for operational efficiency, it does not provide information about the duration of procedures, which is the focus of the study in question. Therefore, it is not the source of data used.
