*How are Emergency Room wait times calculated? Emergency Room wait times represent the average estimated length of
time over a three hour period from registration to "assignment of provider" (a doctor, nurse practitioner or physician assistant).
The wait times displayed on this site are refreshed at least every 30 minutes. Many circumstances can affect wait
times – for example, patients arriving by ambulance or with life-threatening injuries or illnesses. Patients with
life-threatening conditions will be seen before those with less-serious problems or ailments. These times are
provided for informational purposes only and cannot be guaranteed upon arrival. They may be subject to change
without notice. When NA is displayed, the wait time is not available.
