Despite of the changes of out-of-hospital cardiac arrest (OHCA) survival rise when bystander CPR is provided, this was only conducted in about 23% of OHCA patients in Korea in 2018. Police officers acting as first responders have a high chance of witnessing situations requiring CPR. We investigated long-term effects on CPR quality between chest compression-only CPR training and conventional CPR training in police officers to find an efficient CPR training method in a prospective, randomized, controlled trial. Police officers underwent randomization and received different CPR training. With the Brayden Pro application, we compared the accuracy of CPR skills immediately after training and the one after 3 months. Right after training, the conventional CPR group presented the accuracy of the CPR skills (compression rate: 74.6%, compression depth: 66.0%, recoil: 78.0%, compression position: 96.1%) and chest compression-only CPR group presented the accuracy of the CPR skills (compression rate: 74.5%, compression depth: 71.6%, recoil: 79.2%, compression position: 99.0%). Overall, both groups showed the good quality of CPR skills and had no meaningful difference right after the training. However, three months after training, overall accuracy of CPR skills decreased, a significant difference between two groups was observed for compression position (conventional CPR: 80.0%, chest compression only CPR: 95.0%). In multiple linear regression analysis, three months after CPR training, chest compression-only CPR training made CPR skills accuracy 28.5% higher. In conclusion, police officers showed good-quality CPR right after CPR training in both groups. But three months later, chest compression-only CPR training group had better retention of CPR skills. Therefore, chest compression-only CPR training is better to be a standard training method for police officers as first responders.
尽管在实施旁观者心肺复苏术（CPR）时院外心脏骤停（OHCA）患者的生存率有所提高，但2018年韩国只有约23%的OHCA患者接受了旁观者心肺复苏术。作为第一反应者的警察有很高的几率目睹需要进行心肺复苏术的情况。我们在一项前瞻性、随机、对照试验中，研究了仅胸外按压心肺复苏术培训和传统心肺复苏术培训对警察心肺复苏质量的长期影响，以找到一种有效的心肺复苏培训方法。警察接受随机分组并接受不同的心肺复苏培训。通过布雷登专业应用程序，我们比较了培训后立即和3个月后的心肺复苏技能准确性。培训后立即，传统心肺复苏组的心肺复苏技能准确性（按压频率：74.6%，按压深度：66.0%，回弹：78.0%，按压位置：96.1%），仅胸外按压心肺复苏组的心肺复苏技能准确性（按压频率：74.5%，按压深度：71.6%，回弹：79.2%，按压位置：99.0%）。总体而言，两组在培训后立即都显示出良好的心肺复苏技能质量，且没有显著差异。然而，培训三个月后，心肺复苏技能的总体准确性下降，两组在按压位置上观察到显著差异（传统心肺复苏：80.0%，仅胸外按压心肺复苏：95.0%）。在多元线性回归分析中，心肺复苏培训三个月后，仅胸外按压心肺复苏培训使心肺复苏技能准确性提高了28.5%。总之，两组警察在心肺复苏培训后立即都表现出高质量的心肺复苏。但三个月后，仅胸外按压心肺复苏培训组对心肺复苏技能的保留更好。因此，仅胸外按压心肺复苏培训更适合作为警察作为第一反应者的标准培训方法。
