Hawkins NM, Youngson E, Sandhu RK, et al. - Significantly lower admission rates and repeat ED visits were observed in correlation with undergoing treatment in higher volume EDs but there was no difference in survival.

• Four high, 9 medium, and 68 low atrial fibrillation volume EDs with 4,217, 4,193, and 4,112 patients with new atrial fibrillation, respectively.

• No independent association of volume with death or all-cause hospitalization at 30 days and 1 year in patients with new atrial fibrillation.

• Fewer repeat ED visits at 30 days and 1 year were observed at medium- and high-volume EDs.

• Medium- (37.1%) and high- (32.0%) volume EDs had fewer patients admitted relative to low-volume EDs (39.5%).

• More frequently cardioverted patients attended medium- and high-volume EDs.
