Abstract
Objective
The emergency department (ED) length of stay (LOS) is related to ED overcrowding and emergency practice. This study aimed to investigate the effects of enabling an ED doctor to have the authority to make hospitalization decisions and utilization of the emergency ward on ED LOS.
Methods
This retrospective observational study included patients who were admitted through a local emergency medical center. We compared the ED LOS between the periods' March to July 2018 and March to July 2019. In the latter period, ED doctors were authorized to take decisions on patient hospitalizations from the internal medicine department, and the emergency ward was operated under these new conditions.
Results
A total of 6,291 patients were included in the study, with 2,934 in 2018 and 3,357 in 2019. In the comparison of ED LOS for internal medicine inpatients by year, there was a significant reduction in the total ED LOS (1,129.0 [491.0-1,618.0] minutes vs. 539.0 [344.0-1,016.25] minutes, P<0.001), LOS before the admission decision (345.0 [198.0-634.0] minutes vs. 280.0 [176.0-442.3] minutes, P<0.001), and LOS after the admission decision (415.0 [147.0-1,089.0] minutes vs. 179.5 [80.0-422.0] minutes, P<0.001). In a subgroup analysis of internal medicine inpatients in 2019, the admission sheets of an ED doctor showed a significant decrease in LOS before the admission decision (268.0 [170.5-424.5] minutes vs. 404.0 [252.0-570.5] minutes, P<0.001). Also, the utilization of the emergency ward showed a significant decrease in LOS after the admission decision (147.0 [75.0-283.0] minutes vs. 187.0 [81.0-460.0] minutes, P<0.001).
Conclusion
The delegation of hospitalization decisions to the ED doctor and the subsequent utilization of the emergency ward shorten the ED LOS of internal medicine inpatients.
