About this study

Official title: A Survey of Factors Associated With the Successful Recognition of Agonal Breathing and Cardiac Arrest by 9-1-1 Call Takers.

To conduct iterative semi-structured interviews to identify behavioural factors influencing identification of cardiac arrest by 9-1-1 call takers;
To develop a survey instrument about behavioural factors influencing the ability of 9-1-1 call takers to identify cardiac arrest based on a systematic review of the literature, the results of the semi-structured interviews, and theoretical constructs from the Theory of Planned Behaviour; and
To conduct a survey among Ontario 9-1-1 call takers using the survey instrument, and to identify factors and strategies that might be targeted by Knowledge Translation interventions.

Conditions: Cardiac Arrest
Keywords: agonal breathing, cardiac arrest, 9-1-1 call taker, survey
Medical subject headings: Heart Arrest

What does the primary outcome measure?

Intention to Give CPR Instructions (time frame: During a call with a victim potentially in cardiac arrest). 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 NCT00848588, which also lists 1 linked publication.

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.
