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.
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:
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.
