| Summary: | Background: Cardiac arrest is a public health problem with high mortality and may involve despair for the relative losing the person affected. That someone quickly begins cardio pulmonary resuscitation is the first part of the chain that save the person's life and can simultaneously give hope and comfort to the relative. Recently, some counties started using voluntary private individuals to help in sudden cardiac arrest to reduce the time to start of cardiac resuscitation. Objective: To compare the percentage of people who survive after suffering cardiac arrest in the prehospital environment. The comparison is made between the two counties, one of which uses the mobile rescue operation. Method: Two comparable counties were identified, Norrbotten and Västernorrland. Retrospective data from the two counties was collected from the national quality assurance system Hjärt- lungräddningsregistret and was analyzed in SPSS. All cardiac arrests recorded in the register were included. The data were analyzed with Chi-Square test and Fisher's exact test. Bivariate correlations were analyzed with Pearson Correlation Coefficients. Approval for the implementation of the study has been given ethical group in the Department of Health Sciences at Luleå University of Technology. Results: No significant differences between the counties regarding survival could be seen in the results. However it demonstrated a slightly higher survival rate in the county with the mobile rescue operation (10,3% vs 12,8%, p=0,448) as well as a relatively strong correlation between survival and regaining bearing heartbeat at sometime before arrival at hospital (r=0,53, p<0,01). The proportion of when another rescue department than the ambulance was next to the patient before the ambulance unit was higher in the county without mobile rescue operation (19,2% vs 8,8%, p=0,022) and administration of epinephrine was associated with high mortality (r=0,47, p<0,01). Conclusion: Projects aiming at improving the chain that save lives and to reduce the time ...
