Incidence and outcome of patients with difficulty in hospital acceptance during COVID‐19 pandemic in Osaka Prefecture, Japan: A population‐based descriptive study

Abstract

AbstractAimThe impact of the coronavirus disease (COVID‐19) pandemic on the emergency medical service system in Japan has not been fully revealed. The purpose of this study was to determine the impact of the COVID‐19 pandemic in 2021 on the difficulty in hospital acceptance of patients and patient outcome in Osaka Prefecture.MethodsThis study was a descriptive epidemiological study with a 3‐year study period from January 2019 to December 2021. We included patients who were transported by ambulance and had registered in the Osaka Emergency Information Research Intelligent Operation Network (ORION) system. The primary end‐point of this study was the difficulty in hospital acceptance by month, and the secondary outcome was the mortality of patients who experience difficulty in hospital acceptance in each year.ResultsWe included 1,302,646 cases in this study. The proportion of cases with difficulty in hospital acceptance was 2.74% (12,829/468,709) in 2019, 3.74% (15,527/414,987) in 2020, and 5.09% (21,311/418,950) in 2021. The crude odds ratio for 2020 was 1.38 (95% confidence interval, 1.35–1.41) and for 2021 was 1.90 (95% confidence interval, 1.86–1.95). In 2019, 218 patients with difficulty in hospital acceptance had died by 21 days after hospitalization, whereas the number increased to 405 in 2020 and 750 in 2021.ConclusionThe number of patients experiencing difficulty in hospital acceptance during the COVID‐19 pandemic in Osaka Prefecture increased, and patient outcomes were worse than before the pandemic.
