Comparison of results for the modified Emergency Department Work Index (mEDWIN) versus occupancy rate (3a) and Emergency Department Length of Stay (ED-LOS) (3b). 3a. Spearman correlation coefficient 0.947 (95% CI 0.945–0.950). 3b. Spearman correlation coefficient 0.16 (95% CI 0.15–0.18).
Fig 4.
Receiver operating characteristic curves of the modified Emergency Department Work Index (mEDWIN) for emergency department crowding based on the occupancy rate (4a), and on the Emergency Department Length of Stay (ED-LOS) (4b). 4a. Crowded ED, i.e. occupancy rate > 1; AUC mEDWIN = 0.86. 4b. Crowded ED, i.e. ED-LOS ≥ 4 hours; AUC mEDWIN = 0.50.
