What is Emergency Department Wait Time?

Emergency Department Wait Time measures the minutes from patient arrival to first evaluation by a physician. This is a critical patient experience metric reflecting ED efficiency and care access. Longer wait times increase patient dissatisfaction and may delay critical care. Benchmark targets vary by acuity (typically <15 min for emergencies). Directly impacts patient satisfaction and safety perception.
