Which metric best illustrates patient flow efficiency on a medical unit?

• A. Nurse turnover rate during the shift.
• B. Admission/discharge times, bed occupancy, length of stay, transfer times, and wait times.
• C. Number of visitors per patient.
• D. Time to answer call bells.

Answer: (B)

Understanding patient flow efficiency means looking at how quickly and smoothly patients move through the unit from admission to discharge, including transfers and the time they spend waiting for steps in care. The metric set that includes admission and discharge times, bed occupancy, length of stay, transfer times, and wait times best captures this because it covers the full path of patient movement. Admission/discharge times show how fast patients enter and leave the care process, bed occupancy reveals how tightly the unit is loaded and whether bed availability is driving delays, length of stay reflects overall efficiency in getting a patient to disposition, transfer times indicate how quickly patients are moved between units or facilities, and wait times highlight where delays occur along the flow—whether in bed assignment, diagnostic testing, or discharge planning. Together, these elements provide a comprehensive view of throughput and bottlenecks that affect how efficiently patients are moved through care.

Other options focus on aspects not directly tied to flow through the unit: nurse turnover rate examines staffing stability rather than patient movement; number of visitors per patient is more about patient experience than throughput; time to answer call bells relates to responsiveness but not to the movement of patients through the care process.
