Survival Study After Out-of-hospital Cardiac Arrest

Status Recruiting

Clinical Trial Summary

The purpose of this study is to determine if dual dispatch of ambulance, fire fighters and/or police in out-of-hospital cardiac arrest (OHCA), can reduce the time to cardiopulmonary resuscitation (CPR) and defibrillation, thus increasing survival.

Clinical Trial Description

Hypothesis If simultaneous dispatch of ambulance (EMS), firefighters and/or police is being initiated when an OHCA occurs, then the two latter units will be first at scene, before the ambulance crew, in ≥30% of the cases. We anticipate therefore that overall 30-days survival will increase on a national level from 9% to 12%.

Method During the period 110901 to 141231 all OHCA cases will be analyzed were the emergency medical communication centre (EMCC) has dispatched ambulance, firefighters and/or the police. Participating in the Saving More Lives in Sweden (SAMS) project are the following counties: Stockholm, Sodermanland, Jonkoping, Vastra Gotaland (VG Region), Halland, Dalarna, Jamtland, Kalmar and Uppsala. Data is collected by the units being dispatched and thereafter sent on line to a database managed by Registercentrum in Gothenburg (http://www.registercentrum.se/), administrators of the Swedish Cardiac Arrest Register.

Parameters obtained are:

- Time for dispatch of fire fighters and/or police (recorded digitally).

- Time for arrival to the patient.

- Verification if cardiac arrest or not.

- CPR performed by fire fighters or police before arrival of EMS.

- Automated External Defibrillator (AED) connected to the patient.

- If yes, was the first recorded rhythm shockable, i.e. ventricular fibrillation (VF) or pulseless ventricular tachycardia (VT).

- Time to defibrillation.

Survival data during from the Swedish Cardiac Arrest Register (SCAR) will be obtained during the same time period from nine comparable Swedish regions not participating in the SAMS study. ;

Clinical trials are conducted in a series of steps, called phases - each phase is designed to answer a separate research question.

Phase 1: Researchers test a new drug or treatment in a small group of people for the first time to evaluate its safety, determine a safe dosage range, and identify side effects.
Phase 2: The drug or treatment is given to a larger group of people to see if it is effective and to further evaluate its safety.
Phase 3: The drug or treatment is given to large groups of people to confirm its effectiveness, monitor side effects, compare it to commonly used treatments, and collect information that will allow the drug or treatment to be used safely.
Phase 4: Studies are done after the drug or treatment has been marketed to gather information on the drug's effect in various populations and any side effects associated with long-term use.
