To determine if a medication regimen (MET vs DT) associated with decreased financial costs (Secondary Aim-2), ED costs will be examined between the 2 medication regimens in all patients using t-tests, or Mann-Whitney U analysis. In addition, the total cost of hospitalization (ED + hospital costs) of patients admitted to the CAMC hospital from the ED will be examined between the medication regimens. Cost will also be examined in relationship to length of stay by examining cost /length of stay between the two treatment groups using the same statistical tests.
