Read the passage and answer the question.
Patients at Riverside Hospital used to wait an average of four hours in the emergency department. Last spring the hospital tried a simple idea: a senior nurse now meets every patient at the door and decides within ten minutes who needs a doctor first. Patients with minor problems are sent to a nearby clinic that stays open until late evening. The average wait has dropped to just under two hours, and complaints have fallen sharply. Other hospitals in the region are now visiting Riverside to see how the system works.
According to the passage, what has helped to reduce the waiting time?
