Cardiac Arrest, SuddenNCT02473679
Influence of the Education in Layperson in Out of Hospital Resuscitation
An observational study of Cardiac Arrest, Sudden and Heart Arrest, run by University of Zurich at 1 site in Switzerland.
Trial summary
Cardiac arrest occurs frequently and the outcome after out-of-hospital resuscitation is often fatal. Disturbing is that more than half of the surviving patients suffer from permanent impairment of cognitive functions, such attention, memory and executive functioning. Read more about this study

About this study
Official title: Influence of the Education in Layperson Resuscitation and Preparation the Patrol Car of the City Police With Automatic External Defibrillators and Automated Ventilation Equipment on Out of Hospital Resuscitation Outcome
Cardiac arrest occurs frequently and the outcome after out-of-hospital resuscitation is often fatal. Disturbing is that more than half of the surviving patients suffer from permanent impairment of cognitive functions, such attention, memory and executive functioning. With all the efforts to achieve a high quality initial resuscitation management the time delay between cardiac arrest and the beginning the initial resuscitation maneuver is the main reason for the still poor outcome. To shorten this fatal time delay, current efforts of national and supranational health authorities aime at the non-medically trained lay person, who should carry out basic life support directly on the scene supported by the use of public available semi-automatic defibrillators (AED).
Read the detailed description
It is a combined retrospective and prospective observational single center study. Data of all Out of Hospital patients suffered a cardiac arrest in Zurich city will be collected according to the Utstein criteria. The aim of this study is to investigate the impact of trained police forces in the resuscitation outcome.

What is being measured
The primary outcome is the main question the study is designed to answer.
Time line for restoration the circulation
Timeline for restoration the circulation after layperson started the reanimation
Measured: participants will be followed from origin of the event up to 12 month or death
Secondary outcomes (4)
Time interval to first shock ,
Time interval from the emergency call to first shock for ventricular fibrillation
Measured: participants will be followed from origin of the event up to 12 month or death
Neurologic outcome
Data will be collected according to Utstein criteria
Measured: participants will be followed from origin of the event for duration of hospital stay, follow up after 12 month or death
Time interval removal from ICU as well as discharged from hospital
Time interval up to the removal from ICU as well as duration of hospital stay
Measured: participants will be followed from origin of the event up to 12 month or death
Definitive survival rate
Survival rate of participants resuscitated by layperson after cardiac arrest
Measured: participants will be followed from origin of the event up to 12 month or death
