Does the initial description of an out-of-hospital cardiac arrest given by callers contacting Emergency Medical Services contain key indicator words which can be used to support appropriate resource deployment?

This study investigates whether the initial descriptions provided by callers during out-of-hospital cardiac arrest (OHCA) incidents contain key indicator words that can aid Emergency Medical Services (EMS) in resource deployment. By analyzing 37,532 OHCA records, the authors identified specific descriptors that correlate with the likelihood of resuscitation being withheld or survival to 30 days. The findings suggest that incorporating these indicators into EMS protocols could optimize resource allocation and improve patient outcomes.
