Outcome, quality of life and direct costs after out-of-hospital cardiac arrest in an urban region of Switzerland

BackgroundConsidering the significant morbidity and mortality of out-of-hospital cardiac arrest, only little data on survival or quality of life after successful resuscitation is available in Europe. Additionally, economic aspects of such events are poorly studied. The purpose of this study is to provide data for survival, quality of life and costs directly related to the cardiac arrest for a region of Switzerland served by one emergency medical service (EMS).MethodsEighty eight patients older than 18years of age that were resuscitated by the EMS Winterthur in the year 2013 were included and retrospective analysis of EMS-protocols was performed. For patients alive at follow-up, 2years after the event, a structured interview with quality of life questionnaires was conducted. This study was accepted by the local Ethics Committee.ResultsThirty five percent (n=31) of resuscitated patients were admitted alive to the hospital following out-of-hospital cardiac arrest. This incidence was as high as 60%, if the patients had a shockable rhythm as first rhythm. Survival to follow-up was 16% (n=14). These patients had an excellent quality of life overall, with little to no limitations in daily life. There was no significant difference in survival for patients in outlying regions with comparatively longer timespans until arrival of EMS. Median EMS-costs for deceased patients were CHF 1731 (inter-quartile range 346), for survivors CHF 2169 (inter-quartile range CHF 444) and median hospital-costs were CHF 27707 (inter-quartile range CHF 62 ' 783). ConclusionQuality of care for patients with out-of-hospital cardiac arrest in the region of Winterthur is high, including patients in outlying regions. The associated costs are similar to other European countries.Trial registration This trial was registered with www.clinicaltrials.gov under NCT02625883.
