Predictors of post-discharge mortality for critically injured adult trauma patients (2000–2010) who survived index hospitalization (n = 1,119)

Variable	HR (95% CI)
1-year mortality*
ICU LOS >16 days (vs. ≤16 days)	1.66 (1.01, 2.73)
Age per 10-year increase	2.28 (1.93, 2.69)
Male sex (vs. female sex)	2.45 (1.44, 4.19)
Overall mortality (by May 2012)†
ICU LOS >16 days (vs. ≤16 days)	2.22 (1.58, 3.12)
Age per 10-year increase	2.06 (1.85, 2.29)
Male sex (vs. female sex)	1.78 (1.24, 2.55)
