BackgroundBehavioral emergencies account for a significant portion of emergency department (ED) visits in the United States. Substance abuse is common in this population and may precipitate or exacerbate preexisting psychiatric illness. Contrary to ED policy guidelines, many behavior health centers (BH) require a urine drug screen (UDS) in stable patients prior to transfer.ObjectiveWe sought to determine the role of the UDS in ED length of stay (LOS), cost, and charges to patients and inpatient psychiatric care.MethodsWe performed a retrospective chart review of all patients transferred to an in-network BH from September 1–30, 2014. Clinical data were extracted and analyzed from our electronic medical record, including records from both the ED visit and the BH stay.ResultsThere were 205 patient encounters identified; 89 patients had a UDS performed in the ED and 89% were obtained after the ED medical clearance. LOS were similar between the two groups, however, time to ED departure from time of medical clearance was delayed in the UDS group. BH providers mentioned UDS results < 25% of the time and no confirmatory tests were performed. There was no difference in BH LOS or discharge diagnosis of substance-abuse disorder. Patient charges for UDS over the month totaled $21,093.ConclusionThe UDS did not seem to have any significant effect on inpatient psychiatric care; whereas ED LOS and cost were both negatively affected. Based on these results, the UDS seems to be of little-to-no benefit in the setting of acute psychiatric illness.
