Table 4.

Comparison of outcomes between patients with MESS < 8 and MESS of 8 or greater.

	All (n = 230)	MESS < 8 (n = 214)	MESS ≥ 8 (n = 16)	p-value
Total units packed red blood cells (median (Q1, Q3))	3 (0, 8)	3 (0, 8)	8 (2.5, 10)	0.07
Hospital length of stay (median (Q1, Q3))	12 (6, 22)	12 (6, 21)	22.5 (15, 29)	0.006
Days in Intensive Care Unit (median (Q1, Q3))	3 (1, 6)	3 (1, 6)	6 (2, 13)	0.03
Reintervention required, n (%)	35 (15.2)	32 (15)	3 (18.8)	0.5
Damage control primary traumatic amputation, n (%)	21 (9.1)	13 (6.1)	8 (50)	< 0.001
All amputations, n (%)	43 (18.7)	33 (15.4)	10 (62.5)	< 0.001
Death, n (%)	12 (5.2)	10 (4.7)	2 (12.5)	0.2

MESS = mangled extremity severity score

Q1 = Lower quantile (25^th percentile)

Q3 = Upper quantile (75^th percentile)
