Your stay will depend on symptoms, illness, and whether you will be admitted to the hospital as an inpatient. Minor problems can often be handled in a couple of hours or less. Patients with complex illnesses may remain in the ER for several hours.
The time of day and day of the week may also determine how busy the Emergency Department is. Typically, we are busiest between 1 pm and 10 pm. Weekends and Mondays are usually the busiest days of the week.
