BACKGROUND Overall survival rates for out-of-hospital cardiac arrest rarely exceed 5%. While bystander cardiopulmonary resuscitation (CPR) can increase survival for cardiac arrest victims by up to four times, bystander CPR rates remain low in Canada (15%). Most cardiac arrest victims are men in their sixties, they usually collapse in their own home (85%) and the event is witnessed 50% of the time. These statistics would appear to support a strategy of targeted CPR training for an older population that is most likely to witness a cardiac arrest event. However, interest in CPR training appears to decrease with advancing age. Behaviour surrounding CPR training and performance has never been studied using well validated behavioural theories. METHODS/DESIGN The overall goal of this study is to conduct a survey to better understand the behavioural factors influencing CPR training and performance in men and women 55 years of age and older. The study will proceed in three phases. In phase one, semi-structured qualitative interviews will be conducted and recorded to identify common categories and themes regarding seeking CPR training and providing CPR to a cardiac arrest victim. The themes identified in the first phase will be used in phase two to develop, pilot-test, and refine a survey instrument based upon the Theory of Planned Behaviour. In the third phase of the project, the final survey will be administered to a sample of the study population over the telephone. Analyses will include measures of sampling bias, reliability of the measures, construct validity, as well as multiple regression analyses to identify constructs and beliefs most salient to seniors' decisions about whether to attend CPR classes or perform CPR on a cardiac arrest victim. DISCUSSION The results of this survey will provide valuable insight into factors influencing the interest in CPR training and performance among a targeted group of individuals most susceptible to witnessing a victim in cardiac arrest. The findings can then be applied to the design of trials of various interventions designed to promote attendance at CPR classes and improve CPR performance.

对最有可能目睹心脏骤停的老年人群中与成功心肺复苏 (CPR) 知识转移相关的态度和因素的调查：设计和方法。

背景 院外心脏骤停的总体存活率很少超过 5%。虽然旁观者心肺复苏 (CPR) 可以将心脏骤停受害者的生存率提高四倍，但加拿大的旁观者心肺复苏率仍然很低 (15%)。大多数心脏骤停受害者是六十多岁的男性，他们通常倒在自己的家中（85%），并且有 50% 的情况是目击事件。这些统计数据似乎支持针对最有可能目睹心脏骤停事件的老年人群进行有针对性的心肺复苏培训的策略。然而，随着年龄的增长，人们对心肺复苏术培训的兴趣似乎会降低。从未使用经过充分验证的行为理论来研究围绕心肺复苏训练和表现的行为。方法/设计本研究的总体目标是进行一项调查，以更好地了解影响 55 岁及以上男性和女性心肺复苏训练和表现的行为因素。该研究将分三个阶段进行。在第一阶段，将进行并记录半结构化定性访谈，以确定有关寻求心肺复苏培训和向心脏骤停受害者提供心肺复苏的常见类别和主题。第一阶段确定的主题将在第二阶段用于开发、试点测试和完善基于计划行为理论的调查工具。在该项目的第三阶段，最终调查将通过电话对研究人群样本进行。分析将包括抽样偏差的测量、测量的可靠性、构造有效性以及多元回归分析，以确定对老年人决定是否参加心肺复苏课程或对心脏骤停受害者进行心肺复苏的决定最重要的构造和信念。讨论 这项调查的结果将为影响最容易目睹心脏骤停受害者的目标人群对心肺复苏术培训和表现的兴趣的因素提供有价值的见解。然后，研究结果可以应用于设计各种干预措施的试验，这些干预措施旨在提高心肺复苏课程的参加率并提高心肺复苏表现。试验注册 ClinicalTrials.gov NCT00665288。
