A new dispatcher-assisted basic life support training program, called "Home Education and Resuscitation Outcome Study (HEROS)" was developed with a goal to provide high-quality dispatcher-assisted cardiopulmonary resuscitation (CPR) training, with a focus on untrained home bystanders. This study aimed to determine whether the HEROS program is associated with improved quality in CPR performance during training and willingness to provide bystander CPR compared with other basic life support programs without dispatcher-assisted CPR (non-HEROS).
This clustered randomized trial was conducted in 3 district health centers in Seoul. Intervention group was trained with the HEROS program and control group was trained with non-HEROS program. The primary outcome was overall CPR quality, measured as total CPR score. Secondary outcomes were other CPR quality parameters including average compression depth and rate, percentages of adequate depth, and acceptable release. Tertiary outcomes were posttraining survey results. Difference in difference analysis was performed to analyze the outcomes.
Among total 1929 trainees, 907 (47.0%) were trained with HEROS program. Compared with the non-HEROS group, the HEROS group showed higher-quality CPR performances and better maintenance of their CPR quality throughout the course (total scores of 84% vs. 80% for first session and 72% vs. 67% for last session; difference in difference of 12.2 vs. 13.2). Other individual CPR parameters also showed significantly higher quality in the HEROS group. The posttraining survey showed that both groups were highly willing to perform bystander CPR (91.4% in the HEROS vs. 92.3% in the non-HEROS) with only 3.4% of respondents in the HEROS group were not willing to volunteer compared with 6.2% in the non-HEROS group (P < 0.01).
The HEROS training program helped trainees perform high-quality CPR throughout the course and enhanced their willingness to provide bystander CPR.
本研究旨在开发一种新的调度员辅助基础生命支持培训项目，称为“家庭教育和复苏结果研究（HEROS）”，旨在提供高质量的调度员辅助心肺复苏（CPR）培训，重点关注未经培训的家庭旁观者。本研究旨在确定与其他没有调度员辅助 CPR（非 HEROS）的基本生命支持计划相比，HEROS 计划是否与培训期间 CPR 性能的提高以及旁观者 CPR 的意愿相关。
本聚类随机试验在首尔的 3 个区卫生中心进行。干预组接受 HEROS 计划培训，对照组接受非 HEROS 计划培训。主要结局是总体 CPR 质量，以总 CPR 评分衡量。次要结局是其他 CPR 质量参数，包括平均压缩深度和速率、充分深度的百分比以及可接受的释放。三级结局是培训后的调查结果。采用差异中的差异分析来分析结果。
在总共 1929 名受训者中，有 907 名（47.0%）接受了 HEROS 计划培训。与非 HEROS 组相比，HEROS 组在整个培训过程中表现出更高质量的 CPR 表现，并且更好地维持其 CPR 质量（第一次培训的总分 84%，最后一次培训的总分 72%；差异为 12.2%与 13.2%）。HEROS 组的其他个体 CPR 参数也表现出明显更高的质量。培训后的调查显示，两组都非常愿意进行旁观者 CPR（HEROS 组的 91.4%与非 HEROS 组的 92.3%），只有 3.4%的 HEROS 组受访者表示不愿意自愿参加，而非 HEROS 组为 6.2%（P <0.01）。
HEROS 培训计划帮助受训者在整个培训过程中进行高质量的 CPR，并增强了他们提供旁观者 CPR 的意愿。
