Survivorship and Severe Complications Are Worse for Octogenarians and Elderly Patients with Pelvis Fractures as Compared to Adults: Data from the National Trauma Data Bank

Table 5

Multivariate logistic regression analysis for the population with isolated, closed, and severe pelvic fractures (AIS ≥ 3) using predictors upon arrival to the emergency department with the outcomes death and severe complication (odds ratios and 95% confidence intervals).

	Outcome
Model predictors	Death	Severe complication*
	n = 3,101	n = 3,101
Adult (18–64 years)	Referent	Referent
Elderly (65–79)	1.81 (1.16–2.80)	2.18 (1.49–3.19)
Octogenarian; (≥80 years)	4.70 (2.98–7.38)	4.57 (3.01–6.96)
Hypovolemic shock	7.65 (5.45–10.7)	6.31 (4.60–8.66)
Head injury	2.74 (1.81–4.14)	2.86 (1.98–4.13)
ISS** ≥ 16	15.1 (8.76–26.1)	18.3 (11.2–29.9)
Hosmer-Lemeshow^†	0.33	0.43

*Severe complication is defined as having one or more of the following during hospital course: pulmonary embolism, renal failure, acute respiratory distress syndrome, or death.
**ISS: injury severity score.
^†Hosmer-Lemeshow P value given for model’s goodness of fit instead of odds ratio and 95% confidence interval.
