Outcome	Nondelayed	Delayed	Absolute difference	Relative association* (95% CI)

Length of stay, d, mean ± SD	11 ± 19.1	13.6 ± 20.4	2.6	1.21 (1.16–1.25)
Total hospital costs,† $, mean ± SD	19 144 ± 33 900	22 479 ± 40 224	3335	1.17 (1.13–1.21)
Propensity score match adjusted	n = 2820	n = 2820
In-hospital death, no. (%)	90 (3.2)	138 (4.9)	1.7	1.56 (1.18–2.06)
Length of stay, d, mean ± SD	12.5 ± 20.7	13.6 ± 20.4	1.1	1.07 (1.01–1.11)
Total hospital costs,† $, mean ± SD	20 989 ± 35 085	22 479 ± 40 224	1490	1.06 (1.01–1.11)

Note: CI = confidence interval, SD = standard deviation,

^*For death, relative association is odds ratio; for length of stay and costs, relative association is the incidence rate ratio.

^†All costs are in 2014 Canadian dollars.
