An investigation of the chronobiology of out-of-hospital cardiac arrest (OHCA) during the coronavirus disease 2019 (COVID-19) pandemic and the differences in comparison to the 6-year pre-pandemic period. A retrospective analysis of the dispatch cards from the Emergency Medical Service between January 2014 and December 2020 was performed within the OSCAR-POL registry. The circadian, weekly, monthly, and seasonal variabilities of OHCA were investigated. A comparison of OHCA occurrence between the year 2020 and the 6-year pre-pandemic period was made. A total of 416 OHCAs were reported in 2020 and the median of OHCAs during the pre-pandemic period was 379 (interquartile range 337−407) cases per year. Nighttime was associated with a decreased number of OHCAs (16.6%) in comparison to afternoon (31.5%, p < 0.001) and morning (30.0%, p < 0.001). A higher occurrence at night was observed in 2020 compared to 2014−2019 (16.6% vs. 11.7%, p = 0.001). Monthly and seasonal variabilities were observed in 2020. The months with the highest OHCA occurrence in 2020 were November (13.2%) and October (11.1%) and were significantly higher compared to the same months during the pre-pandemic period (9.1%, p = 0.002 and 7.9%, p = 0.009, respectively). Autumn was the season with the highest rate of OHCA, which was also higher compared to the pre-pandemic period (30.5% vs. 25.1%, p = 0.003). The COVID-19 pandemic was related to a higher occurrence of OHCA. The circadian, monthly, and seasonal variabilities of OHCA occurrence were confirmed. In 2020, the highest occurrence of OHCA was observed in October and November, which coincided with the highest occurrence of COVID-19 infections in Poland.
一项关于2019冠状病毒病（COVID-19）大流行期间院外心脏骤停（OHCA）的时间生物学研究以及与大流行前6年期间的差异比较。在OSCAR-POL登记处内，对2014年1月至2020年12月期间紧急医疗服务的调度卡进行了回顾性分析。研究了OHCA的昼夜、每周、每月和季节性变化。对2020年与大流行前6年期间的OHCA发生率进行了比较。2020年共报告了416例OHCA，大流行前期间OHCA的中位数为每年379例（四分位间距337 - 407）。与下午（31.5%，p < 0.001）和上午（30.0%，p < 0.001）相比，夜间OHCA的数量减少（16.6%）。与2014 - 2019年相比，2020年夜间OHCA的发生率更高（16.6%对11.7%，p = 0.001）。2020年观察到了每月和季节性变化。2020年OHCA发生率最高的月份是11月（13.2%）和10月（11.1%），与大流行前同一月份相比显著更高（分别为9.1%，p = 0.002和7.9%，p = 0.009）。秋季是OHCA发生率最高的季节，与大流行前期间相比也更高（30.5%对25.1%，p = 0.003）。COVID-19大流行与OHCA的较高发生率相关。OHCA发生率的昼夜、每月和季节性变化得到了证实。2020年，OHCA发生率最高出现在10月和11月，这与波兰COVID-19感染的最高发生率相吻合。
