Objective: Emergency department (ED) overcrowding is a global issue that negatively impacts the clinical outcome.
Through the coronavirus disease 2019 (COVID-19) pandemic era, overcrowding of ED isolated territory (isolation bed) was aggravated. This study analyzed overcrowding indices of ED isolation beds during the COVID-19 pandemic.
Methods: This study was a single-center, retrospective, observational study. The study analyzed 34,925 patients who visited the ED during the COVID-19 pandemic from April 2021 to August 2022. Patients who were treated in isolation beds and regular beds were compared. Among the patients using isolation beds, patients who stayed longer than 720 minutes were also classified and analyzed.
Results: During the analysis period, 4,479 and 34,943 patients were treated in the ED isolation bed and ED regular bed, respectively. The overcrowding indices (general ward admission rate, intensive care unit admission rate, ED-length of stay, transfer rate, mortality rate, prolonged ED stay patient ratio) of the isolation beds were significantly higher than those of the ED regular bed (P<0.05). The prolonged ED stay-patient ratio of isolation beds and regular beds was affected by the number of COVID-19 patients (regular bed, r=0.617 and P=0.01; isolation bed, r=0.525 and P=0.03). The average ED-length of stay of isolation beds was longer than that of the ED regular beds. One hundred and forty-five patients were classified as prolonged ED stay patients. Their time from the decision point to the discharge point comprised a higher rate with an average of 76.52%.
Conclusion: ED isolation beds are more vulnerable to infectious disease outbreaks. A proper medical policy and arrangement management system that can flexibly deal with disaster emergencies are required
