The aim of this study was to investigate effects of basic life support (BLS) training on willingness of single rescuers to make emergency calls during out-of-hospital cardiac arrests (OHCAs) with no available help from others.
A cross-over questionnaire survey was conducted with two questionnaires. Questionnaires were administered before and after two BLS courses in fire departments. One questionnaire included two scenarios which simulate OHCAs occurring in situations where help from other rescuers is available (Scenario-M) and not available (Scenario-S). The conventional BLS course was designed for multiple rescuers (Course-M), and the other was designed for single rescuers (Course-S).
Of 2,312 respondents, 2,218 (95.9%) answered all questions and were included in the analysis. Although both Course-M and Course-S significantly augmented willingness to make early emergency calls not only in Scenario-M but also in Scenario-S, the willingness for Scenario-M after training course was significantly higher in respondents of Course-S than in those of Course-M (odds ratio 1.706, 95% confidential interval 1.301-2.237). Multiple logistic regression analysis for Scenario-M disclosed that post training (adjusted odds ratio 11.6, 95% confidence interval 7.84-18.0), age (0.99, 0.98-0.99), male gender (1.77, 1.39-2.24), prior BLS experience of at least three times (1.46, 1.25-2.59), and time passed since most recent training during 3 years or less (1.80, 1.25-2.59) were independently associated with willingness to make early emergency calls and that type of BLS course was not independently associated with willingness. Therefore, both Course-M and Course-S similarly augmented willingness in Scenario-M. However, in multiple logistic regression analyses for Scenario-S, Course-S was independently associated with willingness to make early emergency calls in Scenario-S (1.26, 1.00-1.57), indicating that Course-S more efficiently augmented willingness. Moreover, post training (2.30, 1.86-2.83) and male gender (1.26, 1.02-1.57) were other independent factors associated with willingness in Scenario-S.
BLS courses designed for single rescuers with no help available from others are likely to augment willingness to make early emergency calls more efficiently than conventional BLS courses designed for multiple rescuers.
本研究旨在探讨基础生命支持（BLS）培训对单个救援人员在没有其他救援人员帮助的情况下拨打急救电话的意愿的影响。
在消防部门进行了两次 BLS 课程后，采用交叉问卷调查的方式进行了问卷调查。调查问卷包括两个情景，模拟有其他救援人员帮助（情景-M）和没有其他救援人员帮助（情景-S）的情况下发生的院外心脏骤停（OHCA）。传统的 BLS 课程是为多名救援人员设计的（课程-M），另一个是为单人救援人员设计的（课程-S）。
在 2312 名应答者中，有 2218 名（95.9%）回答了所有问题并纳入分析。虽然课程-M 和课程-S 都显著提高了不仅在情景-M 而且在情景-S 中进行早期紧急呼叫的意愿，但在课程-S 培训后的情景-M 中，课程-S 的应答者的意愿明显高于课程-M（优势比 1.706，95%置信区间 1.301-2.237）。对情景-M 的多变量逻辑回归分析显示，培训后（调整后的优势比 11.6，95%置信区间 7.84-18.0）、年龄（0.99，0.98-0.99）、男性（1.77，1.39-2.24）、至少三次以前的 BLS 经验（1.46，1.25-2.59）和 3 年内最近一次培训后（1.80，1.25-2.59）与早期紧急呼叫的意愿独立相关，BLS 课程类型与意愿不独立相关。因此，课程-M 和课程-S 都同样提高了情景-M 中的意愿。然而，在情景-S 的多变量逻辑回归分析中，课程-S 与情景-S 中进行早期紧急呼叫的意愿独立相关（1.26，1.00-1.57），表明课程-S 更有效地提高了意愿。此外，培训后（2.30，1.86-2.83）和男性（1.26，1.02-1.57）是与情景-S 中意愿相关的其他独立因素。
为没有其他救援人员帮助的单人救援人员设计的 BLS 课程可能比为多名救援人员设计的传统 BLS 课程更有效地提高进行早期紧急呼叫的意愿。
