RESUMEN
BACKGROUND: In the chain of survival for Out-of-hospital cardiac arrest (OHCA), each component of care contributes to improve the prognosis of the patient with OHCA. The SARS-CoV-2 (COVID-19) pandemic potentially affected each part of care in the chain of survival. The aim of this study was to compare prehospital care, in-hospital treatment, and outcomes among OHCA patients before and after the COVID-19 pandemic. METHODS: We analyzed data from a multicenter prospective study in Kanto area, Japan, named SOS-KANTO 2017. We enrolled patients who registered during the pre-pandemic period (September 2019 to December 2019) and the post-pandemic period (June 2020 to March 2021). The main outcome measures were 30-day mortality and the proportion of favorable outcomes at 1 month, and secondary outcome measures were changes in prehospital and in-hospital treatments between the pre- and post-pandemic periods. RESULTS: There were 2015 patients in the pre-pandemic group, and 5023 in the post-pandemic group. The proportion of advanced airway management by emergency medical service (EMS) increased (p < 0.01), and EMS call-to-hospital time was prolonged (p < 0.01) in the post- versus pre-pandemic group. There were no differences between the groups in defibrillation, extracorporeal membrane oxygenation, or temperature control therapy (p = 0.43, p = 0.14, and p = 0.16, respectively). Survival rate at 1 month and favorable outcome rate at 1 month were lower (p = 0.01 and p < 0.01, respectively) in the post- versus pre-pandemic group. CONCLUSION: Survival rate and favorable outcome rate 1 month after return of spontaneous circulation of OHCA worsened, EMS response time was prolonged, and advanced airway management by EMS increased in the post- versus pre-pandemic group; however, most prehospital and in-hospital management did not change between pre- and post-COVID-19 pandemic.

Aim: Prescription drug and over-the-counter (OTC) drug overdose is a major problem in emergency departments in Japan, and some need advanced care which is more than observation. We aimed to identify the prehospital risk factors for the need of advanced care among overdose patients. Methods: This was a single-center retrospective cohort study. We included overdoses patients of prescription drugs or OTC drugs, who admitted to our hospital between 2016 and 2021. We grouped them into advanced care and non-advanced care. The main outcome was the need for advanced care. We performed a multiple logistic regression analysis, calculated the PAV score (Paracetamol use, Alcohol use, abnormal Vital signs on scene) and performed a receiver operating characteristic (ROC) analysis. Results: There were 229 subjects. The logistic regression analysis revealed that alcohol, paracetamol, and the abnormal vital signs on scene were associated with advanced care (alcohol-odds ratio [OR]: 2.95; 95% confidence interval [CI]: 1.29-6.75; paracetamol-OR: 5.47; 95% CI: 2.18-13.71; abnormal vital signs-OR: 4.61, 95% CI: 2.07-10.27). The rate of advanced care in the high PAV score (2 and 3) group was statistically higher than that in the low PAV score (0-1) group (p = 0.04). Area under the ROC curve of the PAV score was 0.72 (95% CI, 0.65-0.80). Conclusion: Alcohol, paracetamol use and abnormal vital signs on scene might be risk factors for advanced care among prescription drugs or OTC drugs overdose patients, and the PAV score may predict the need for advanced care.
