Idaho 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 Idaho 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.
