简要总结
The study aims to investigate bystanders' emotional stress state in out-of-hospital cardiac arrest (OHCA) emergency calls and the association with the quality of dispatcher-assisted cardiopulmonary resuscitation (DA-CPR).
详细描述
Delayed CPR is believed to be an important factor in the outcome of out-of-hospital cardiac arrest (OHCA). Bystanders' emotional stress state might affect recognition of cardiac arrest and the resuscitation attempt. The study aims to investigate the association between a bystander's emotional stress state at the beginning of the emergency call in out-of-hospital cardiac arrest (OHCA) and dispatcher-assisted cardiopulmonary resuscitation (DA-CPR).
Method
The study is a retrospective and observational study of OHCA emergency calls from the capital region of Denmark from 01.09.2018 - 01.11.2019. The audio recordings of the emergency calls will be obtained from the emergency medical service database. A code catalogue with standardised default descriptions to each variable will be used. The study will only include the first person whom the medical dispatcher talk to. The rating of the calls will be performed by five observers outside of the research group, who have no conflict of interest.
The primary outcome of the present study will be to investigate an association between a bystander's emotional stress state in the beginning of the emergency call of OHCA and the time until first chest compression. Secondarily, the study investigated the association between the bystander's emotional stress and:
