aP values of age, hospital charges, hospital length of stay, and ED length of stay were derived from Kruskal–Wallis test. P values of sex, ethnicity, GCS, and ISS were derived from Pearson’s Chi-square test. P values of age category, race, and ED disposition were derived from Fisher’s exact test

bIQR stands for interquartile range

Bold values indicate a percentage change with a 95% confidence interval that does not cross 0
