ObjectivesIn response to crowding the use of hallway beds has become an increasingly prevalent practice in Emergency Departments (EDs). There is limited research on whether caring for patients in hallways (HP) is associated with adverse outcomes. The goal of this study was to examine the effects of HP triage on 30 day outcomes for ED return, readmission, and mortality.MethodsWe performed a retrospective cohort study at an urban, academic ED comparing HPs (defined as HP for ≥30 min) to matched controls triaged to standard ED beds from 9/30/14 to 10/1/15. We analyzed data from the hospital's clinical data warehouse. Matched controls were selected by gender, age, ethnicity, and language. We used McNemar's test to assess the association between triage location and 30 day study outcomes. We also examined adverse outcomes by triage severity using McNemar's test.ResultsA total of 10,608 HPs were matched to control patients. Compared to controls, HPs had 2.0 times the odds of returning to the ED in 30 days (95% CI: 1.8-2.1), 1.6 times the odds of inpatient readmission (95% CI: 1.4-1.9), and 1.7 times the odds of readmission to observation (95% CI: 1.4-2.0). The odds ratio for mortality in HPs versus controls was 0.80, (95% CI: 0.50-1.3).ConclusionsPatients initially triaged to the hallway have an increased odds of 30 day return to the ED, observation and inpatient admission. After adjusting for ESI, the increased odds for return remained similar. The small sample size precluded testing effects of HP status on mortality.Copyright © 2018 Elsevier Inc. All rights reserved.
