Mathematical Modeling of the Impact of Hospital Occupancy: When Do Dwindling Hospital Beds Cause ED Gridlock?

Table 1

Overall characteristics for study period of 200 days.

ED census (mean ± SD)	124 ± 16
Left-without-being-seen % (median, IQR)	0.9 (0 to 1.8)
Length of stay (LOS) minutes (median, interquartile range)	339 (236 to 594)
% higher acuity triage (class 1, 2, or 3)	64 ± 5
% Inpatient occupancy (median, interquartile range)	90 (85 to 95)
