Brief Summary

The overall goal of this study is to better understand the factors leading to successful dispatch-assisted CPR instructions and to ultimately save the lives of more cardiac arrest patients. Specific objectives are to: 1) Determine the ability of 9-1-1 dispatchers to make the diagnosis of cardiac arrest over the phone; 2) Quantify the frequency and impact of perceived agonal breathing on cardiac arrest diagnosis; 3) Measure the frequency with which dispatch-assisted CPR instructions can be successfully completed in out-of-hospital cardiac arrest cases; and 4) Measure the impact of dispatch-assisted CPR instructions on bystander CPR and survival rates for out-of-hospital cardiac arrest.

Outcome Measures

Primary Outcomes (1)

• Sensitivity

  Number of true cardiac arrest cases correctly identified

  At time of 9-1-1 call

Other Outcomes (1)

• Specificity

  At time of 9-1-1 call

Study Arms (1)

Potential cardiac arrest calls

All 9-1-1 calls for unconscious patients will be included over the timeframe January 2008 and October 2009 in the participating communities to determine cardiac arrest diagnostic accuracy by 9-1-1 call takers

Eligibility Criteria

• Age: 16 Years+
• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Patients with out-of-hospital cardiac arrest

You may qualify if:

• All patients with out-of-hospital cardiac arrest (absence of a detectable pulse, unresponsiveness, and apnea) that are:
• Of presumed cardiac origin;
• Occurring in our study communities; and
• For which resuscitation is attempted by a bystander and/or the emergency responders; or for which dispatch-assisted CPR instructions are being provided.

You may not qualify if:

• The following patients will be excluded:
• Patients younger than 16 years;
• Patients who are "obviously dead" as defined by the Ambulance Act of Ontario (decomposition, rigor mortis, decapitation, or other);
• Trauma victims, including hanging and burns; or
• Patients with cardiac arrests clearly of other non-cardiac origin including drug overdose, carbon monoxide poisoning, drowning, exsanguination, electrocution, asphyxia, hypoxia related to respiratory disease, cerebrovascular accident and documented terminal illness.
