Multivariate analysis for clinical management and outcome variables

	Pre-travel consultation (compared to no pre-travel consultation)a
	Unadjusted odds ratio (95% confidence interval)	Partially adjusted odds ratio (95% confidence interval)b	Fully adjusted odds ratio (95% confidence interval)c
Infectious Disease Consult	5.1 (3.6–7.2)	5.4 (3.8–7.7)	3.1 (1.9–5.3)
Gastroenterology Consult	0.3 (0.1–0.6)	0.2 (0.1–0.5)	0.4 (0.2–0.9)
Mean Days of Hospitalization	p = 0.009	p = 0.06	p = 0.006
Pre-travel consult	1.8 days	1.8 days	1.8 days
No pre-travel consult	3.3 days	3.3 days	3.3 days
Stool sample obtained	1.9 (1.4–2.5)	1.9 (1.4–2.5)	1.6 (1.1–2.4)
Antimicrobial prescribed	1.6 (1.2–2.2)	1.7 (1.2–2.3)	1.6 (1.1–2.5)

^aA nominal logistic model was used for categorical variables. Least squares means were used to estimate the mean hospitalization duration based on a linear model. P values were calculated based on least squares means

^bPartially adjusted model included age, sex, and race

^cFully adjusted model included age, sex; race; local residence; employment; travel destinations (Central America, South America, Sub-Saharan Africa, South Asia, Southeast Asia, Northeast Asia, Caribbean); unsanitary food and water consumption; rural location; hiking; camping
