Report: Maryland has the longest ER visits: 4 hr 1 min at the typical hospital (Oct 25, 2026)
Fastest to slowest ER wait times in Wisconsin, 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 Wisconsin 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.

Questions about Wisconsin ER wait times
Which Wisconsin ER has the shortest wait?
Edgerton Hospital and Health Services in Edgerton, with a median visit of 1 hr 11 min. Moundview Memorial Hsptl and Clinics in Friendship is next at 1 hr 13 min.
Which Wisconsin ER has the longest wait?
Froedtert Memorial Lutheran Hsptl, at 4 hr 35 min. The busiest emergency departments tend to have the longest visits because they treat more patients and more complex cases.
How long is the average ER visit in Wisconsin?
The median is 2 hr 16 min, 12 min shorter than the US median of 2 hr 28 min. 33 of 118 Wisconsin ERs come in under two hours and 1 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 Wisconsin ERs have a median visit of 2 hr 4 min. High and very-high-volume ERs come in at 2 hr 46 min. Large hospitals see more patients and sicker ones, and many are trauma centers.
