GFT correlated with both number of positive influenza tests as seen in Figure 1 (adult ED r 00.876, pediatric ED r 00.718) and number of ED patients presenting with ILI (adult ED r00.885, pediatric ED r 00.652). Pediatric but not adult crowding measures such as total ED volume (r 00.649) and left without being seen (r 00.641) also had good correlation with GFT. Adult crowding measures for low acuity patients such as waiting room time (r00.421) and length of stay in discharged patients (r00.548) had moderate correlation with GFT.
