South Dakota emergency room wait times
ER wait times › South Dakota
Across 53 South Dakota hospitals that report the measure, the median emergency department visit lasts 1 hr 54 min — 36 min shorter than the national median of 2 hr 30 min. The shortest is Coteau Des Prairies Health Care System at 44 min.
Medians over a full year, for patients treated and discharged rather than admitted. Busy hospitals treat sicker patients, so a longer wait is not by itself a mark against a hospital. How this measure works.
