Impact of emergency department length of stay on in-hospital mortality: a retrospective cohort study.
Background and importance: Emergency Department (ED) workload may lead to ED crowding and increased ED length of stay (LOS). ED crowding has been shown to be associated with adverse events and increasing mortality. We hypothesised that ED-LOS is associated with mortality.
Objective: To study the relationship between ED-LOS and in-hospital mortality.
Design: Observational retrospective cohort study.
Settings and participants: From 1 January 2015 to 30 September 2018, all visits by patients aged 15 or older to one of the two ED at Toulouse University Hospital were screened. Patients admitted to the hospital after ED visits were included. Visits followed by ED discharge, in-ED death or transfer to ICU or another hospital were not included.
Outcome measure and analysis: The primary outcome was 30-day in-hospital mortality. ED-LOS was defined as time from ED registration to inpatient admission. ED-LOS was categorised according to quartiles [<303 min (Q1), between 303 and 433 minutes (Q2), between 434 and 612 minutes (Q3) and >612 min (Q4)]. A multivariable logistic regression tested the association between ED-LOS and in-hospital mortality.
Main results: A total of 49 913 patients were admitted to our hospital after ED visits and included in the study. ED-LOS was not independently associated with in-hospital mortality. Compared to ED-LOS < 303 min (Q1, reference), odd-ratios (OR) [95% CI] of in-hospital mortality for Q2, Q3, and Q4 were respectively 0.872 [0.747-1.017], 0.906 [0.777-1.056], and 1.137 [0.985-1.312]. Factors associated to in-hospital mortality were: aged over 75 years (OR [95% CI] = 4.3 [3.8-4.9]), Charlson Comorbidity Index score > 1 (OR [95% CI] = 1.3 [1.1-1.5], and 2.2 [1.9-2.5] for scores 2 and ≥ 3 respectively), high acuity at triage (OR [95% CI] = 3.9 [3.5-4.4]), ED visit at Hospital 1 (OR [95% CI] = 1.6 [1.4-1.7]), and illness diagnosis compared to trauma (OR [95% CI] = 2.1 [1.7-2.6]). Night-time arrival was associated with decreased in-hospital mortality (OR [95% CI] = 0.852 [0.767-0.947]).
Conclusion: In this retrospective cohort study, there was no independent association between ED-LOS before admission to general non-ICU wards and in-patient mortality.
期刊介绍：
The European Journal of Emergency Medicine is the official journal of the European Society for Emergency Medicine. It is devoted to serving the European emergency medicine community and to promoting European standards of training, diagnosis and care in this rapidly growing field.
Published bimonthly, the Journal offers original papers on all aspects of acute injury and sudden illness, including: emergency medicine, anaesthesiology, cardiology, disaster medicine, intensive care, internal medicine, orthopaedics, paediatrics, toxicology and trauma care. It addresses issues on the organization of emergency services in hospitals and in the community and examines postgraduate training from European and global perspectives. The Journal also publishes papers focusing on the different models of emergency healthcare delivery in Europe and beyond. With a multidisciplinary approach, the European Journal of Emergency Medicine publishes scientific research, topical reviews, news of meetings and events of interest to the emergency medicine community.
Submitted articles undergo a preliminary review by the editor. Some articles may be returned to authors without further consideration. Those being considered for publication will undergo further assessment and peer-review by the editors and those invited to do so from a reviewer pool.
