Results. A total of 2549 patients were analyzed and
then stratified into the two groups: PHI and No-PHI.
There was a significant difference noted in overall
mortality (90.2% versus 12.4%), with the PHI group
being more likely to succumb to their injuries. After
adjusting for possible confounding factors, multivariable
logistic regression analysis demonstrated that
PHI was independently associated with increased
mortality (AOR 5, 95% CI: 1.7–13.7, P [ 0.004).
