Continuous data were analyzed using t-tests and dichotomous data were analyzed using Fisher’s exact tests with significance delineated at p <0.05
aOne subject in the intervention group reported his race to be African American and Native American and one subject from the usual care group reported his race to be “Mexican”
*One subject from the usual care group had a length of stay of 26 days and was excluded from the average calculation
