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 2

Multivariate logistic regression analysis for the entire population of closed pelvic fractures 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 = 31,475	n = 31,475
Adult (18–64 years)	Referent	Referent
Elderly (65–79)	2.35 (2.10–2.62)	2.19 (1.98–2.42)
Octogenarian; (≥80 years)	3.60 (3.19–4.04)	2.87 (2.57–3.21)
Head injury	1.62 (1.42–1.84)	1.59 (1.41–1.79)
ISS** ≥ 16	10.4 (9.26–11.7)	9.54 (8.62–10.6)
Hosmer-Lemeshow^†	0.34	0.08

*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.
