ER Wait Times in Columbus, OH: 5 Hospitals Compared
5 hospitals in Columbus, OH report how long their emergency room patients stay. The middle value here is 178 minutes; Ohio: 155 minutes; national (Medicare): 162 minutes.
What this time means
Each hospital’s number is Medicare measure OP-18b: the median (middle) time from arriving at the emergency room to leaving it, for patients who were treated and went home. Half of these patients left sooner, half later. It is not the time before seeing a doctor, and it leaves out patients who were admitted to the hospital, transferred, or seen for mental health.
Medicare’s name for the measure: “Average (median) time patients spent in the emergency department before leaving from the visit, excluding patients transferred to another facility or psychiatric care/mental health patients. A lower number of minutes is better”. Patients seen October 2024 to September 2025.

Common questions
Which ER in Columbus, OH has the shortest wait?
In Medicare's data for October 2024 to September 2025, Mount Carmel East & West had the shortest median time patients spent in the emergency room before going home: 147 minutes. This is the total time of the visit, not the time before seeing a doctor, and it is an average of past patients, not a promise for your visit.
What is the average ER wait time in Columbus, OH?
The middle value of the 5 hospitals listed here is 178 minutes; for all of Ohio it is 155 minutes. The national figure published by Medicare is 162 minutes. Each hospital's number is the median time from arriving at the emergency room to leaving it, for patients who were treated and went home.
Should I drive to a farther ER to wait less?
No. In an emergency, call 911 or go to the nearest emergency room. These times are past averages; emergency rooms see the sickest patients first, and minutes lost on the road can matter more than minutes in a waiting room.
Does a shorter time mean a better emergency room?
Not by itself. Busier emergency rooms and hospitals that treat more serious cases usually have longer times, so the ER volume is shown next to each time. The time is one measure among many on each hospital’s page.
