Abstract

Aim

This study aims to assess the impact of the COVID-19 pandemic on out-of-hospital cardiac arrest (OHCA) incidence, bystander cardiopulmonary resuscitation (CPR), EMS resuscitation attempts and survival across Australia and New Zealand.

Method

Data were extracted for all OHCAs patients attended by emergency medical services (EMS) between 2017 and 2021 from the Aus-ROC OHCA Epistry (Epidemiological registry). Logistic regression was used to explore differences between the pre-COVID-19 (January 1, 2017 to March 15, 2020) and COVID-19 (March 16, 2020 to December 31, 2021) periods for bystander CPR, EMS-attempted resuscitation, survival to hospital arrival (event survival) and survival to hospital discharge/30 days.

Results

The incidence of OHCA increased during COVID-19 in Australia and New Zealand, although this varied regionally. When compared to the pre-COVID-19 period, COVID-19 was associated with a significant increase in the odds of an EMS-attempted resuscitation in Queensland (adjusted odds ratio (aOR) = 1.19; 95%CI: 1.01–1.40, p = 0.03) and Western Australia (aOR = 1.26; 95%CI: 1.03–1.54, p = 0.02). The COVID-19 period was associated with a decrease in survival to hospital arrival in Australia overall (aOR = 0.91; 95% CI:0.83–0.99, p = 0.04), and by region in Victoria (aOR = 0.74; 95% CI:0.63–0.87, p < 0.01) and Tasmania (aOR = 0.48; 95% CI:0.25–0.91, p = 0.02), and with a decrease in survival to hospital discharge/30 days in Australia (aOR = 0.82; 95% CI:0.70–0.96, p = 0.01), and by region in Victoria (aOR = 0.70; 95% CI:0.54–0.91, p < 0.01) and South Australia (aOR = 0.61; 95% CI:0.37–0.99, p = 0.04). There were no significant changes in survival during COVID-19 in New Zealand.

Conclusion

Regional variations were observed with respect to the associations of COVID-19 with resuscitation attempts and OHCA survival.

在澳大利亚和新西兰，COVID-19大流行对复苏尝试、旁观者心肺复苏术和生存结果的影响：一项基于两国人群的Epistry研究

目的本研究旨在评估2019冠状病毒病（COVID-19）大流行对澳大利亚和新西兰院外心脏骤停（OHCA）发生率、旁观者心肺复苏（CPR）、EMS复苏尝试和生存率的影响。方法从Aus-ROC OHCA Epistry（流行病学登记）中提取2017年至2021年间急诊医疗服务（EMS）的所有OHCA患者的数据。采用Logistic回归探讨2019冠状病毒病前（2017年1月1日至2020年3月15日）和2019冠状病毒病（2020年3月16日至2021年12月31日）期间旁观者心肺复苏术、ems -试图复苏、到达医院生存期（事件生存期）和出院生存期/30天之间的差异。结果澳大利亚和新西兰的OHCA发病率在2019冠状病毒病期间有所增加，但区域差异较大。与COVID-19前相比，COVID-19与昆士兰州ems试图复苏的几率显着增加有关(调整后的优势比(aOR) = 1.19；95%CI: 1.01-1.40, p = 0.03)和西澳大利亚州(aOR = 1.26；95%CI: 1.03 ~ 1.54, p = 0.02)。总体而言，2019冠状病毒病期间与澳大利亚到达医院的生存率下降有关(aOR = 0.91；95% CI: 0.83-0.99, p = 0.04)，维多利亚地区(aOR = 0.74；95% CI: 0.63-0.87, p <；0.01)和塔斯马尼亚(aOR = 0.48；95% CI: 0.25-0.91, p = 0.02)，并且在澳大利亚，到出院/30天生存率降低(aOR = 0.82；95% CI:0.70 - 0.96, p = 0.01)，维多利亚地区(aOR = 0.70；95% CI: 0.54-0.91, p <；0.01)和南澳大利亚(aOR = 0.61；95% CI: 0.37-0.99, p = 0.04)。在新西兰，COVID-19期间的生存率没有显著变化。结论COVID-19与复苏次数和OHCA存活的相关性存在区域差异。
