Fastest to slowest ER wait times in Illinois, by hospital

Times are for patients treated and sent home, not admitted. The bar shows each ER against the slowest in the state; the tick marks the Illinois median.

How to read this list

Each time is the median for a full year, so half of visits were shorter and half longer. Busy hospitals treat sicker patients, so a longer time is not by itself a mark against a hospital. "Left before seen" is the share of patients who walked out before a clinician saw them. How this measure works.

Pinckneyville Community Hospital in Pinckneyville, with a median visit of 49 min. Washington County Hospital in Nashville is next at 1 hr 24 min.

Which Illinois ER has the longest wait?

Rush University Medical Center, at 6 hr 10 min. The busiest emergency departments tend to have the longest visits because they treat more patients and more complex cases.

The median is 2 hr 53 min, 25 min longer than the US median of 2 hr 28 min. 25 of 155 Illinois ERs come in under two hours and 17 take four hours or more.

Are these live wait times?

No. They are 12-month medians for patients who were treated and sent home, published by CMS. They show what is typical, not what is happening tonight. In an emergency, call 911.

Why are big hospitals slower?

Low-volume Illinois ERs have a median visit of 2 hr 4 min. High and very-high-volume ERs come in at 3 hr 38 min. Large hospitals see more patients and sicker ones, and many are trauma centers.
