Brief Summary

Death from cardiac disease is one of the most common causes of death in the western world. The majority of these deaths takes place outside hospital as sudden cardiac death. However, with immediate (within minutes) actions such as cardiopulmonary resuscitation (CPR) and defibrillation many lives would be saved. CPR is a key factor to increase survival from Out of Hospital Cardiac Arrest (OHCA). CPR buys time by supporting the brain with some circulation in waiting for a defibrillator that can restart the heart. In Sweden about 2,5 million people are trained in CPR. However, only about half of all OHCA victims will get CPR in waiting for ambulance arrival. The aims of the Response to Urgent Mobile message for Bystander Activation (RUMBA) trial is to try a new way of logistics to increase bystander CPR by recruiting lay volunteers to nearby OHCAs via their mobile phones. Hypothesis: By dispatching lay volunteers to nearby OHCAs with mobile phone technology bystander CPR may increase from 50% to 62,5 %

Keywords

Out of hospital cardiac arrest; Cardiopulmonary resuscitation; Bystander CPR; Mobile phone positioning system

Outcome Measures

Primary Outcomes (1)

• Bystander CPR by trained bystander before arrival of ambulance, firefighters or police

  Bystander CPR is defined as CPR by trained laymen in Out of hospital Cardiac Arrest patients before arrival of ambulance, firefighters or police and this only in OHCA patients were care is continued by ambulance crew. CPR in cases showing obvious signs of death are excluded. Telephone assisted CPR by untrained laymen is not accounted for as bystander CPR.

  Within 1 hour from randomization

Secondary Outcomes (7)

• OHCAs were lay volunteers dispatched by the mobile positioning system arriving prior to ambulance

  Within 1 hour from randomization

• Time of bystander CPR before arrival of ambulance, firefighters or police

  Within 1 hour from randomization

• Rhythm on first ECG

  Within 1 hour from randomization

• Return of spontaneous circulation (ROSC)

  Within 3 hours from randomization

• Admitted alive

  24 hours after hospital admission

Study Arms (2)

MLS dispatch for bystander CPR

EXPERIMENTAL

When an alarm call of a suspected OHCA suspected is received by the EMS dispatch operator a Mobile positioning system (MPS) is activated. The MPS uses the mobile phone network to geographically locate all lay volunteers connected to a tailored mobile phone service called mobile life saver (MLS). The MPS then locates all lay volunteers within a pre defined radius from the suspected OHACA an alerts them with a computer generated voice call and an sms containing data about were about were the suspected OHCA is located. A map is also sent in order to make route finding easy.
