Abstract

Objective
Overcrowded emergency departments (ED) are a worldwide problem, which could cause treatment delays and increased mortality of patients. This study aimed at evaluating the effect of admission decisions by emergency physicians without consultation of an internal medicine doctor on the emergency department length of stay (ED LOS) and survival rate of patients diagnosed with medical disease.
Methods
The study was a retrospective observational study comparing the ED LOS of patients admitted to the internal medicine (IM) department before and after the policy change regarding admission decisions, implemented in July 2017. During and after the policy change, emergency physicians took decisions on the arrangements and treatment for patients by processing their admission and providing follow-up care without further specialist consultations. The ED LOS and rate of admission to the IM department were compared between the study period (October 2017 to October 2018) and the control period (June 2016 to June 2017).
Results
The median ED LOS of patients admitted to the IM department decreased from 164.0 minutes (interquartile range [IQR], 118.0-234.0) in the control period to 114.0 minutes (IQR, 104.0-208.0) in the study period. After propensity score matching, the median ED LOS of patients admitted to the IM department decreased from 187.0 minutes (IQR, 136.0-253.0) in the control period to 144.0 minutes (IQR, 104.0-208.0) in the study period.
Conclusion
The admission decisions made by emergency physicians reduced the ED and hospital LOS of patients visiting the ED and diagnosed with medical disease.
