About this study
Official title: A Survey of Attitudes and Factors Associated With Successful Cardiopulmonary Resuscitation (CPR) Knowledge Transfer in an Older Population Most Likely to Witness Cardiac Arrest
The goal of this study is to conduct a survey to better understand the factors associated with undertaking cardiopulmonary resuscitation (CPR) training and performing CPR in an emergency situation.
Read the detailed description
Background: Overall survival rate for out-of-hospital cardiac arrest rarely exceeds 5%. While bystander cardiopulmonary resuscitation (CPR) can increase survival for cardiac arrest victims up to four times, bystander CPR rates remain low in Canada (15%). Survivors have a quality of life similar to the general population. Most cardiac arrest victims are men in their sixties; they usually collapse in their own home (85%), where bystander CPR rates are even lower. The event is witnessed by a family member or bystander 50% of the time. These statistics appear to support a strategy of targeted CPR training for an older population that is most likely to witness a cardiac arrest event. Interest in CPR training appears to decrease with advancing age. Behaviour surrounding CPR training and performance has never been studied using the theoretical constructs of a well validated behavioural theory (the Theory of Planned Behaviour).
Objectives: The overall goal of this study is to conduct a survey to better understand the behavioural factors associated with successful CPR knowledge transfer in an independent-living older population (aged 55 or more). Specific objectives are: 1) To conduct semi-structured qualitative interviews to identify factors influencing CPR training and performance behaviours; 2) To then develop a survey instrument about factors influencing CPR training and performance behaviours based on a systematic review of the literature, the results of the semi-structured interviews, and theoretical constructs; and 3) To conduct a telephone survey among an independent-living population aged 55 or more using the survey instrument, and to identify factors and strategies that might be targeted by KT interventions.
Methods: Objective 1: We will tape-record semi-structured qualitative interviews conducted among 20 randomly selected participants aged 55 or older, and perform inductive analyses to identify categories and themes. Objective 2: The survey instrument will be developed based on a completed systematic review of the literature, and results from objective 1. The two behaviours under study will be �seeking CPR training and providing CPR to a cardiac arrest victim�. Objective 3: We will develop and conduct a nation-wide telephone survey using random digit dialling. The telephone survey will be centrally administered and stratified by province and large or small communities in order to obtain a representative random sample of the Canadian population. The study population will include all men and women aged 55 or older, living independently in the community, with the ability to communicate in English or French. We will seek to obtain a participation rate of 60% or greater. We estimate requiring approximately 500 respondents to identify factors and strategies for improving CPR KT in our target population. 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.

What is being measured
The primary outcome is the main question the study is designed to answer.
Measure the Intent to Engage in CPR Training or Intent to Perform CPR
Mean intention to complete CPR training in the next 6 months as well as intention to perform CPR on a victim in cardiac arrest was assessed using a 5-point Likert scale with higher scores indicating stronger intentions (1=strongly disagree, 2=disagree, 3=neither agree nor disagree, 4=agree, 5=strongly agree).
Measured: 1 hour

Where is the study taking place?
The record lists 1 site in Canada. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Yes. Results are posted in the registry (first posted 21 Mar 2024). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Measure the Intent to Engage in CPR Training or Intent to Perform CPR (time frame: 1 hour). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT00665288, which also lists 3 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 Mar 2024.
