Purpose: This study investigated the differences between patients with acute carbon monoxide (CO) poi soning who visited the emergency department (ED) before and during the coronavirus disease 2019(COVID-19) pandemic.
Methods: This was a single-center retrospective observational study. Patients with CO poisoning whovisited the ED during the period from February 2020 to January 2023 were classified as the COVID-19pandemic group, and those from February 2019 to January 2020 were classified as the non-pandemicgroup. Patients’ medical records were reviewed, their demographic and clinical characteristics were com pared, and the length of stay in ED was checked. The time from admission to the ED to the start of hyper baric oxygenation (HBO) was defined as the door-to-HBO time, and this parameter was compared be tween both groups.
Results: In total, 672 patients were included in this study. The proportion of intentional poisoning wassignificantly higher in the COVID-19 pandemic group than in the non-pandemic group (p=0.028). Theproportion of intentional poisoning significantly increased in the 20- to 29-year-old age group during theCOVID-19 pandemic (p<0.001). In addition, it took longer to initiate HBO in the COVID-19 pandemicgroup than in the non-pandemic group (p=0.001).
Conclusion: These findings suggest that pandemics of infectious diseases, such as COVID-19, increase theproportion of intentional CO poisoning, and it may take longer to initiate HBO after visiting the ED. Ef forts will be needed to decrease intentional CO poisoning and length of stay in ED.
