The influence of the Tokyo Summer Olympic/Paralympic Games on normal emergency medical system operations in Japan had not yet been fully elucidated. In this study, we examined whether out-of-hospital cardiac arrest (OHCA) patients treated during the Tokyo Olympic/Paralympic Games had differences in outcomes.
Using the nationwide JAAM-OHCA Registry, we evaluated the outcomes of OHCA patients admitted to the hospital during the Tokyo Olympic/Paralympic Games (July 23 to Aug. 8 and Aug. 24 to Sept. 5) in 2021, compared to those during same the dates in 2020 (Term 1: July 23 to Aug. 8 and Aug. 24 to Sept. 5), those during the pre-Olympic/Paralympic term during the same weekdays in the weeks before the event (Term 2: June. 18 to July. 4 and July. 6 to July. 18), and those during the post-Olympic/Paralympic term during the same weekdays in the weeks after the event (Term 3: Sept. 10 to Sept. 26 and Sept. 28 to Oct. 10). The primary outcome was 30-day survival, and multivariable logistic analysis was performed, adjusted for age and sex.
A total of 3,111 OHCA patients were included in the study period (786 in the Olympic/Paralympic group, 774 in Term 1, 747 in Term 2, and 804 in Term 3). Crude 30-day survivals were 7.4% (58/786), 9.3% (72/774), 6.8% (51/747), and 8.2% (66/804), respectively. Using the Olympic/Paralympic group as a reference, multivariable logistic analysis revealed that 30-day survivals in Term 1 (OR 1.27 95% CI 0.88-1.83p = 0.20), Term 2 (OR 0.92 95% CI 0.62-1.36p = 0.67), and Term 3 (OR 1.10 95% CI 0.76-1.59p = 0.63) did not differ significantly.
No significant differences in 30-day survival for OHCA patients admitted during the Tokyo Summer Olympic/Paralympic Games were identified.
东京夏季奥运会/残奥会对日本正常紧急医疗系统运作的影响尚未完全阐明。在本研究中，我们调查了在东京奥运会/残奥会期间接受治疗的院外心脏骤停（OHCA）患者在预后方面是否存在差异。
我们使用全国性的JAAM - OHCA登记系统，评估了2021年东京奥运会/残奥会期间（7月23日至8月8日以及8月24日至9月5日）入院的OHCA患者的预后，并与2020年同一日期（第1期：7月23日至8月8日以及8月24日至9月5日）、赛事前几周相同工作日的奥运会/残奥会前期（第2期：6月18日至7月4日以及7月6日至7月18日）以及赛事后几周相同工作日的奥运会/残奥会后期（第3期：9月10日至9月26日以及9月28日至10月10日）的患者进行比较。主要结局是30天生存率，并进行了多变量逻辑分析，对年龄和性别进行了调整。
研究期间共纳入3111例OHCA患者（奥运会/残奥会组786例，第1期774例，第2期747例，第3期804例）。30天粗生存率分别为7.4%（58/786）、9.3%（72/774）、6.8%（51/747）和8.2%（66/804）。以奥运会/残奥会组为参照，多变量逻辑分析显示，第1期（比值比1.27，95%置信区间0.88 - 1.83，p = 0.20）、第2期（比值比0.92，95%置信区间0.62 - 1.36，p = 0.67）和第3期（比值比1.10，95%置信区间0.76 - 1.59，p = 0.63）的30天生存率无显著差异。
未发现东京夏季奥运会/残奥会期间入院的OHCA患者在30天生存率上存在显著差异。
