California emergency rooms ranked by median visit time
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 California 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 California ER wait times
Which California ER has the shortest wait?
Trinity Hospital in Weaverville, with a median visit of 1 hr 9 min. Southern Monterey County Memorial Hospital in King City is next at 1 hr 14 min.
Which California ER has the longest wait?
Loma Linda University Medical Center, at 6 hr 53 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 California?
The median is 2 hr 54 min, 26 min longer than the US median of 2 hr 28 min. 22 of 273 California ERs come in under two hours and 37 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 California ERs have a median visit of 2 hr 20 min. High and very-high-volume ERs come in at 3 hr 15 min. Large hospitals see more patients and sicker ones, and many are trauma centers.
