Background: The novel corona virus (COVID-19) pandemic occurred worldwide. Although an excessive burden was placed on emergency medical institutions treating urgent and severe patients, its impact on patient outcome remains unknown. This study aimed to assess the impact of the COVID-19 pandemic in 2021 on the emergency medical services (EMS) system and patient outcomes in Osaka Prefecture, Japan.

- The study aimed to examine how the COVID-19 pandemic influenced ambulance transports for self-harm in Japan from 2018 to 2021, focusing on identifying vulnerable age groups.
- Researchers used a comprehensive database from the Osaka Prefectural Government, analyzing ambulance transports for self-harm among 10,843 patients, primarily women with a median age of 38.
- Results showed a slight increase in the incidence rate over the years, but no significant change in the overall incidence or 21-day mortality due to self-harm was found, although there was an 11.7% increase in the 20-29 age group in 2020.
Aim: The 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.
Methods: This study was a descriptive epidemiological study with a 3-year study period from January 2019 to December 2021.
Background: Little is known about the transport and outcomes of emergency patients with cardiocerebrovascular diseases in Japan before and during the COVID-19 pandemic.
Methods and results: Data were extracted from a population-based registry in Osaka, Japan, from 2019 to 2021. There were almost no differences in the numbers of emergency patients hospitalized with myocardial infarction, stroke, or heart failure or their deaths.
Article Synopsis
- The study aimed to identify the types of medical conditions causing dizziness and how patients were treated in the Emergency Department (ED) over a three-year period in Osaka, Japan.
- Nearly 4% of a total of 1,346,457 patients transported to hospitals by ambulance experienced dizziness, with "dizziness and giddiness" being the most common diagnosis among 53,190 cases.
- The research found that 22.3% of these dizzy patients were admitted to the hospital, and there was no significant increase in emergency admissions during the COVID-19 pandemic compared to 2018.
Aim: The spread of coronavirus disease 2019 (COVID-19) has a widespread impact on emergency medical care systems. However, its effects on the mortality of emergency transportation patients are unclear. This population-based, cross-sectional study investigated how COVID-19 impacted the mortality and outcomes of emergency transportation patients.

Objective: To assess the effect of the COVID-19 pandemic on the emergency medical service (EMS) and hospital admission course for children transported by ambulance.
Methods: This study was a retrospective, descriptive study with a study period from January 1, 2018 to December 31, 2020 using the Osaka Emergency Information Research Intelligent Operation Network (ORION) system.
Background: The coronavirus disease 2019 (COVID-19), caused by Severe Acute Respiratory Syndrome Coronavirus 2, has spread rapidly across the world.
Objective: To assess the influence of the COVID-19 pandemic on the emergency medical service (EMS) for transportation of pregnant women by ambulance.
Methods: This study was a retrospective, descriptive study using the Osaka Emergency Information Research Intelligent Operation Network system, and included pregnant women transported by ambulance in Osaka Prefecture between January 1, 2018 and December 31, 2020.
Background: We investigated factors associated with prolonged viral clearance of SARS-CoV-2 among non-severe adult patients in Osaka, Japan. A total of 706 laboratory-confirmed COVID-19 patients were enrolled in this longitudinal observational study between 29 January 2020 and 31 May 2020, across 62 hospitals and three non-hospital recuperation facilities.
Methods: Logistic regression analysis was performed to investigate the factors associated with prolonged (29 days: upper 25% in duration) viral clearance of SARS-CoV-2.
Aim: Details such as diagnosis and outcome of patients transported by ambulance after telephone triage have not been fully revealed. The aim of this study was to reveal profile and outcome about patients transported by ambulance via telephone triage with dataset of telephone triage and population-based registry for emergency patients.
Methods: This retrospective descriptive study with a one-year study period from January 1, 2016 to December 31, 2016 included patients selected from the telephone triage dataset who were transported by ambulance.
Objective: To describe the detailed clinical course of patients with coronavirus disease 2019 (COVID-19) who received invasive mechanical ventilation.
Methods: We conducted a case series of patients with COVID-19 who received invasive mechanical ventilation in Osaka, Japan, between January 29 and May 28, 2020. We describe the patient characteristics and clinical course from onset.
We report a case involving a 76-year-old woman with transverse colon cancer undergoing long-term chemotherapy following palliative colonic stent placement. She visited our hospital with a diagnosis of colonic obstruction. Her abdomen was evidently distended and tender.
