Résumé
Background: The 2020 COVID- 19 pandemic had various effects on local healthcare. The aim of this study was to assess the extent to which local healthcare and healthcare workers were affected by the COVID- 19 pandemic. Method(s): In this observational study we examined and compared intensive care units (ICUs) before (2019) and during (2020) the COVID- 19 pandemic to assess its effects. Emergency patient data were obtained from the Saitama Prefecture Emergency Medical Information System. The effect of COVID- 19 on emergency care responses was compared with the admission and refusal of patients in 2019 and 2020. We also examined the number of patients who were admitted to ICUs and required surgery. The effect on ICUs was examined with the number of Nurses' incident reports and severity percentages calculated from the integrated team medical care and safety system. We also compared the overtime hours of physicians on the basis of employment records. Result(s): In 2019, 2,136 emergency requests were made to admit patients, and 1,811 patients (85%) were admitted. In contrast, in 2020, 2,371 emergency requests were made, and 1,822 patients (76%) were admitted, representing a decrease to 76% (p = 0.931). The percentage of patients for whom admission was refused was significantly greater in 2020 (506 patients, 21.3%) than in 2019 (303 patients, 14.1%;p = 0.0004). In 2020, the number of neurosurgical, cardiac, and vascular operations increased and, over time, the number of operations increased for all surgical units. The number of incidents reported in ICUs increased significantly from 396 in 2019 to 510 in 2020 (p = 0.001). Conclusion(s): Although intensive care management was restricted, the numbers of patients and physician overtime hours were greater during the COVID- 19 pandemic than before, and the resulting environment led to an increase in the number of incidents. The ICU environments must be proactively improved to prepare for more severe situations in the future.Copyright © 2022 Jikei University School of Medicine. All rights reserved.
