Objective To describe the characteristics and outcome in out-of-hospital cardiac arrest (OHCA) in relation to (i) whether OHCA was coded by the dispatcher as a diagnosis or as a symptom and (ii) the delay until the first unit was alerted at the dispatch centre. Methods OHCA patients in Goteborg, during 17 months, excluding OHCA after calling the rescue team. Results Among 250 cases, 20% were coded as a diagnosis (i. e. CA) with or without ongoing cardiopulmonary resuscitation (CPR). Dispatch codes for the remaining 200 patients (80%) were mostly symptom related (unconsciousness in 61%, codes related to breathing problems in 10%, other codes in 24% and missing in 5%). Patients in whom the dispatchers coded the call as CA had an earlier start to CPR after collapse (median 2 vs. 10 min; P < 0.0001) and a higher rate of bystander CPR (86% vs. 42%; P < 0.0001). Furthermore, they tended to have a higher rate of survival to hospital discharge (14.0% vs. 6.5%; P = 0.09). The median delay until the first unit was alerted was 1.8 min. Survival to hospital discharge was 10.0% if the delay was below median and 6.7% if the delay was above median (P = 0.48). Conclusion Patients with OHCA who were not coded by dispatchers as such had a long delay to the start of CPR and a low survival. Dispatching according to diagnosis, that is, CA seems to improve these parameters most likely reflecting a more optimal communication between the dispatcher and the caller as well as the rescue team.
