Q1) 50 patients per hour arrive at ER. Under proposed triage plan, patients who are entering will be registered as before. They will then be speedily studied by nurse practitioner who will categorize them as Simple Prescriptions or Potential Admits. While Simple Prescriptions will move on to area staffed for regular care, Potential Admits will be taken to emergency area. Planners anticipate that initial examination by triage nurse will take 3 minutes. They expect that, on average, 20 patients will be waiting to register and 5 will be waiting to be seen by triage nurse. Recall that registration takes average of 2 minutes per patient. Planner expects Simple Prescriptions area to have, on average, 15 patients waiting to be seen. As before, once patient's turn comes, each will take 5 minutes of doctor's time. Hospital anticipates that, on average; emergency area will have only 1 patient waiting to be seen. As before, once patient's turn comes, he or she will take 30 minutes of doctor's time. Suppose that, as before, 90% of all patients are Simple Prescriptions. Suppose, too, that triage nurse is 100% accurate in her classifications. Under proposed plan, how long, on average, will patient stay in ER? On average, how long will Potential Admit stay in ER? On average, how many patients will be in the ER?
