TL;DR: In this paper , the effect of coronavirus disease 2019 (COVID-19) on out-of-hospital cardiac arrest (OHCA) outcomes in South Korea was evaluated by a systematic review and meta-analysis.
Abstract: Purpose To evaluate the effect of coronavirus disease 2019 (COVID-19) on out-of-hospital cardiac arrest (OHCA) outcomes in South Korea, we conducted systematic review and meta-analysis. Materials and Methods MEDLINE, Embase, KoreaMed, and Korean Information Service System databases were searched up to June 2022. We included observational studies and letters on OHCA during the COVID-19 pandemic and compared them to those before the pandemic. Epidemiologic characteristics, including at-home OHCA, bystander cardiopulmonary resuscitation, unwitnessed arrest, use of an automated external defibrillator (AED), shockable cardiac rhythm, and airway management, were evaluated. Survival and favorable neurological outcomes were extracted. We conducted a meta-analysis of each characteristic and outcome. Results Six studies including 4628 OHCA patients were included in this study. The incidence of at-home OHCA significantly increased and the AED use decreased during the COVID-19 pandemic compared to before the pandemic [odds ratio (OR), 1.29; 95% confidence interval (CI), 1.08–1.55; I2=0% and OR, 0.74; 95% CI, 0.57–0.97; I2=0%, respectively]. Return of spontaneous circulation after OHCA, survival, and favorable neurological outcomes during and before the pandemic did not differ significantly (OR, 0.90; 95% CI, 0.71–1.13; I2=37%; OR, 0.74; 95% CI, 0.43–1.26; I2=72%; OR, 0.77; 95% CI, 0.43–1.37; I2=70%, respectively). Conclusion During the COVID-19 pandemic in South Korea, the incidence of at-home OHCA increased and AED use decreased among OHCA patients. However, survival and favorable neurological outcomes did not significantly differ from before the pandemic. This insignificant effect of the pandemic on OHCA in South Korea could be attributed to the slow increase in patient count in the early days of the pandemic.

TL;DR: Prehospital times significantly increased after the intervention in all patients (p < 0.001) and by disease group; all prehospital times except for the scene time of cardiac arrest patients increased.
Abstract: During the coronavirus disease 2019 (COVID-19) pandemic, prehospital times were delayed for patients who needed to arrive at the hospital in a timely manner to receive treatment. To address this, in March 2020, the Korean government designated emergency medical centers for critical care (EMC-CC). This study retrospectively analyzed whether this intervention effectively reduced ambulance diversion (AD) and shortened prehospital times using emergency medical service records from 219,763 patients from the Gyeonggi Province, collected between 1 January and 31 December 2020. We included non-traumatic patients aged 18 years or older. We used interrupted time series analysis to investigate the intervention effects on the daily AD rate and compared prehospital times before and after the intervention. Following the intervention, the proportion of patients transported 30–35 km and 50 km or more was 13.8% and 5.7%, respectively, indicating an increased distance compared to before the intervention. Although the change in the AD rate was insignificant, the daily AD rate significantly decreased after the intervention. Prehospital times significantly increased after the intervention in all patients (p < 0.001) and by disease group; all prehospital times except for the scene time of cardiac arrest patients increased. In order to achieve optimal treatment times for critically ill patients in a situation that pushes the limits of the medical system, such as the COVID-19 pandemic, even regional distribution of EMC-CC may be necessary, and priority should be given to the allocation of care for patients with mild symptoms.

TL;DR: In this paper , the authors compared the regional and temporal features of cardiac arrest prognosis and epidemiological characteristics during the COVID-19 pandemic with before the pandemic, and found that the outcomes exhibited similar patterns.
Abstract: 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).

TL;DR: Growing evidence on the safety of CPR during COVID-19 and resuscitation training courses implemented with specific CPR manoeuvres to reduce the risk of infection should ideally avoid any recrudescence of this backstep in bystander CPR culture.
Abstract: Likely, COVID-19 is not an unknown enemy anymore. Two years have passed since the first case was reported in Wuhan, and now much more information about this disease is available, together with vaccines and new therapies, that have significantly reduced the sever-ity of this infection and let the community learn how to live together with this virus. Finally, growing evidence on the safety of CPR during COVID-19 and resuscitation training courses implemented with specific CPR manoeuvres to reduce the risk of infection should ideally avoid any recrudescence of this backstep in bystander CPR culture. Lay people need to be reassured about not going back to the XIII century: ‘ Which accident, and other the like, if not far greater, begat divers feares and imaginations in them that beheld them, all tending to a most inhumane and uncharitable end; namely, to flie thence from the sicke, and touching any thing of theirs, by which meanes they thought their health should be safely warranted ’ (G. Boccaccio, Decameron, 1349 – 1353) .

TL;DR: In this article , a comprehensive review of the performance indicators available in the literature to assess the quality of acute care in OECD countries and their trends during the first year and a half of the COVID-19 pandemic (2020-July2021).
Abstract: Abstract Background: The COVID-19 pandemic severely impacted health systems, leading to care disruptions for non-COVID patients. Performance indicators to continuously monitor acute care, timely reported and internationally accepted, lacked during the COVID-19 pandemic in OECD countries. Methods: Scoping review. Search in Embase and MEDLINE databases. Acute care performance indicators were collected and collated following the care pathway; indicators related to acute general surgery were analyzed separately. Results: A total of 152 studies were included. 2354 indicators regarding general acute care and 301 indicators related to acute general surgery were collected and collated. Indicators focusing on pre-hospital services reported a decreasing trend in the volume of patients: from 225 indicators, 110 (49%) reported a decrease. An increasing trend in pre-hospital treatment times was reported by most of the indicators (n=41;70%) and a decreasing trend in survival rates of out-of-hospital cardiac arrest (n=61;75%). Concerning care provided in the emergency department, most of the indicators (n=752;71%) showed a decreasing trend in admissions, across all levels of urgency (n=26, 51% of highly urgent/level 1 indicators; n=20, 56% of level 2; n=31, 67% of level 3 and 4; and n=43, 78% of non-urgent/level 5 indicators). Indicators assessing the volume of diagnostic and treatment procedures signaled reductions: 65% (n=85) of the indicators and 51% (n=54) of the indicators, respectively. Concerning the mortality rate after admission, most of the indicators (n=23;53%) reported an increasing trend. The subset of indicators assessing acute general surgery showed a decreasing trend in the volume of patients reported by most of the indicators (n=50,49%), stability in clinical severity at admission (n=36,53%), and stability in the volume of surgeries (n=14,47%). Most of the indicators (n=28,65%) reported no change in treatment approach and stable mortality rate (n=11,69%). Conclusions: This review summarizes the performance indicators available in the literature to assess the quality of acute care in OECD countries and their trends during the first year and a half of the COVID-19 pandemic (2020-July2021). These results highlight the relevance of assessing the acute care pathway more regularly and systematically across different clinical entities, to monitor care disruptions and improve the resilience of emergency services to crises.
