Association between improvement in hospital-level median ED LOS and improvement in other quality of care indicators. The figure depicts the rate ratio (difference-in-differences, computed as a ratio of ratios on the log scale) of better performance on specific quality indicators comparing the change in performance over the study period among hospitals that had improved median ED LOS with the change in performance among hospitals that had not improved. As shown in the figure, none of the quality indicators was associated with shift-level crowding. AMI, acute myocardial infarction; ASA, acetylsalicylic acid; ED, emergency department; LOS, length of stay; STEMI, ST-elevated myocardial infarction.
