Bystander CPR is vital in improving outcomes for out-of-hospital cardiac arrest. There has been ample literature describing disparities in bystander CPR within specific countries, such as the United States, Australia, and the Netherlands. However, there has not been significant literature describing such disparities between countries.
We examined various studies published between 2000 and 2021 that reported rates of bystander CPR in various countries. These bystander CPR rates were correlated with the GDP per capita of that country during the time the study was conducted. The correlation between GDP per capita and rates of bystander CPR was assessed.
A total of 29 studies in 35 communities across 25 countries were examined. Reported rates of bystander CPR ranged from 1.3% to 72%. From this, a strong and significant correlation between GDP per capita and rates of bystander CPR was apparent; 0.772 (p < .01), r = 0.596.
GDP per capita can be thought of as a composite endpoint that takes into account various aspects of a country's social and economic well-being. Socioeconomically-advantaged communities likely have a better ability to provide CPR education to community members, and our findings mirror localized analyses comparing socioeconomic status and rates of bystander CPR. Future studies should continue to elucidate transnational disparities in cardiac arrest, and efforts should be directed at providing CPR education to communities with low rates of bystander CPR; low-and-middle-income countries may represent attractive targets for such interventions. However, it may be possible that rates of bystander CPR may not improve unless significant upstream improvements to socioeconomic factors take place.
旁观者心肺复苏术对于改善院外心脏骤停的预后至关重要。有大量文献描述了特定国家（如美国、澳大利亚和荷兰）旁观者心肺复苏术的差异。然而，还没有关于国家之间这种差异的重要文献。
我们研究了 2000 年至 2021 年间发表的各种研究，这些研究报告了不同国家的旁观者心肺复苏术的比率。这些旁观者心肺复苏术的比率与研究期间该国的人均 GDP 相关。评估了人均 GDP 与旁观者心肺复苏术比率之间的相关性。
共检查了来自 25 个国家的 35 个社区的 29 项研究。报告的旁观者心肺复苏术比率从 1.3%到 72%不等。由此可见，人均 GDP 与旁观者心肺复苏术的比率之间存在着很强且显著的相关性；0.772（p <.01），r = 0.596。
人均 GDP 可以被视为一个综合终点，考虑了一个国家社会和经济福祉的各个方面。在社会经济上处于有利地位的社区可能更有能力向社区成员提供心肺复苏术教育，我们的发现反映了比较社会经济地位和旁观者心肺复苏术比率的局部分析。未来的研究应继续阐明心脏骤停方面的跨国差异，并应努力向旁观者心肺复苏术比率较低的社区提供心肺复苏术教育；中低收入国家可能是此类干预措施的理想目标。然而，除非社会经济因素发生重大的上游改善，否则旁观者心肺复苏术的比率可能不会提高。
