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 South Dakota, 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 South Dakota 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.
