Maryland emergency room wait times

ER wait times › Maryland

Across 46 Maryland hospitals that report the measure, the median emergency department visit lasts 4 hr 4 min — 1 hr 34 min longer than the national median of 2 hr 30 min. The shortest is Garrett County Memorial Hospital at 2 hr 6 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.
