Predicted Risk of Hospital Complication by Gender, Vulnerability, and Injury Severity

Men:
Risk of complication or death (95% CI)
Low ISS (≤ 15) High ISS (≥ 16)
Not Vulnerable
(VES-13 ≤ 2)		 8.6%
(0.2-18.8%)		 40.7%
(10.4-70.0%)
Vulnerable
(VES-13 ≥ 3)		 29.0%
(3.6-59.3%)		 74.9%
(44.3-97.8%)
Women:
Probability of complication or death (95% CI)
Low ISS (≤ 15) High ISS (≥ 16)
Not Vulnerable
(VES-13 ≤ 2)		 3.8%
(0%-13.5%)		 22.7%
(.4-66.0%)
Vulnerable
(VES-13 ≥ 3)		 14.8%
(.4-41.0%)		 56.0%
(10.5-93.7%)

VES-13 = Vulnerable Elders-13 Survey, cutoff for vulnerability of ≥3 from Saliba et al17 ISS = Injury Severity Score

Predicted risks are based on logistic regression model using dichotomous VES-13, dichotomous ISS, gender, and co-morbidity. Actual number of non-vulnerable subjects with low ISS, vulnerable with low ISS, non-vulnerable with high ISS, and vulnerable with high ISS were n=12, 15, 13, and 13, respectively. Predicted risks were obtained by setting the sample to male and female for genderspecific estimates. 95% confidence intervals were obtained via bootstrapping with replacement.
