“…These factors are closely related to the number of initial COVID-19 cases, and it can be assumed that the impact on the health system and OHCA was lower because the number of COVID-19 patients in Asia and the Republic of Korea was relatively low compared with Europe and North America during the initial pandemic period. In the Republic of Korea, the initial increase in cases showed a different trend than the United States and Europe, indicating that the OHCA survival rate during the pandemic and pre-pandemic period was not significantly different ( 19 ).…”

“…In particular, Asian countries, such as the Republic of Korea and Japan, tried to contain the entry and spread of COVID-19 through stronger controls in the early stages of the outbreak ( 88 ). These approaches led to more available medical resources that could afford to operate relatively efficiently, resulting in a lower impact of the COVID-19 pandemic on OHCA ( 19 , 89 ).…”

“…Hospitalizations and mortality rates increased for patients with acute myocardial infarction and ischemic stroke, complication rates in patients with acute peritonitis increased, and time to surgery was delayed ( 14–16 ). The incidence and mortality rates of OHCA, which has a very high fatality rate when immediate appropriate treatment is not given, have also increased ( 18 , 19 ). In addition, the desire to “social distance” may have led to a decrease in EMS or hospital utilization in serious cases.…”

The coronavirus disease of 2019 (COVID-19) pandemic, directly and indirectly, affected the emergency medical care system and resulted in worse out-of-hospital cardiac arrest (OHCA) outcomes and epidemiological features compared with those before the pandemic. This review compares the regional and temporal features of OHCA prognosis and epidemiological characteristics. Various databases were searched to compare the OHCA outcomes and epidemiological characteristics during the COVID-19 pandemic with before the pandemic. During the COVID-19 pandemic, survival and favorable neurological outcome rates were significantly lower than before. Survival to hospitalization, return of spontaneous circulation, endotracheal intubation, and use of an automated external defibrillator (AED) decreased significantly, whereas the use of a supraglottic airway device, the incidence of cardiac arrest at home, and response time of emergency medical service (EMS) increased significantly. Bystander CPR, unwitnessed cardiac arrest, EMS transfer time, use of mechanical CPR, and in-hospital target temperature management did not differ significantly. A subgroup analysis of the studies that included only the first wave with those that included the subsequent waves revealed the overall outcomes in which the epidemiological features of OHCA exhibited similar patterns. No significant regional differences between the OHCA survival rates in Asia before and during the pandemic were observed, although other variables varied by region. The COVID-19 pandemic altered the epidemiologic characteristics, survival rates, and neurological prognosis of OHCA patients.Review registration: PROSPERO (CRD42022339435).

“…During the early stages of the pandemic, the majority of medical resources were focused on the care of patients with COVID-19, and the pandemic impacted the systems of emergency medical centers and affected the diagnosis and treatment processes of patients without COVID-19 [ 1 , 2 , 3 ]. Furthermore, a gap in emergency medical services developed for other diseases, including myocardial infarction, stroke, out-of-hospital cardiac arrest (OHCA), and sepsis, owing to the collateral effects [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ]. Previous studies have revealed that patients with these life-threatening diseases experienced delays in arrival through overburdened emergency medical services and medical institutions with limited capacity, restricting their access to proper care [ 2 , 3 , 4 , 5 , 6 , 7 , 8 ].…”

Background and Objectives: We investigated epidemiological factors and outcomes, including the development of complications, for patients with appendicitis according to three sequential coronavirus disease 2019 (COVID-19) pandemic periods, divided by specific time points. Materials and Methods: This observational study included patients with acute appendicitis who arrived at a single-center between March 2019 and April 2022. The study divided the pandemic into three periods: period A as the first phase of the pandemic (from 1 March 2020 to 22 August 2021), period B as the time period the medical system stabilized (from 23 August 2021 to 31 December 2021), and period C as the time period of the exploration of patients with COVID-19 in South Korea (from 1 January 2022 to 30 April 2022). Data collection was based on medical records. The primary outcome was presence or absence of complications and the secondary outcomes were the time taken from ED visit to surgical intervention, the presence and time of the first administration of antibiotics, and the hospital stay time. Results: Of 1,101 patients, 1,039 were included, with 326 and 711 patients before and during the pandemic, respectively. Incidence of complications was not affected during the pandemic (before the pandemic 58.0%; period A 62.7%; period B,55.4%; and period C 58.1%; p = 0.358). Time from symptom onset to emergency department (ED) arrival significantly decreased during the pandemic (before the pandemic 47.8 ± 84.3 h; pandemic 35.0 ± 54 h; p = 0.003). Time from ED visit to the operating room was statistically significantly increased during the pandemic (before the pandemic 14.3 ± 21.67 h; period A 18.8 ± 14.02 h; period B 18.8 ± 8.57 h; period C 18.3 ± 12.95 h; p = 0.001). Age and time from symptom onset to ED arrival were variables affecting the incidence of complications; however, they were not affected during the pandemic (age, OR 2.382; 95% CI 1.545–3.670; time from symptom onset to ED arrival, OR 1.010, 95% CI 1.006–1.010; p < 0.001). Conclusions: This study found no differences in postoperative complications or treatment durations between pandemic periods. The incidence of appendicitis complications was significantly influenced by age and the duration between the onset of symptoms and arrival at the emergency department, but not by the pandemic period itself.
