Abstract

Abstract : Background: The study aimed to investigate whether a bystander's emotional stress state affects DA-CPR in OHCA. The primary outcome was time from recognition of OHCA by the medical dispatcher until first chest compression delivered. Secondarily, we investigated time from recognition of OHCA until initiation of CPR-instructions as well as quality of DA-CPR instructions according to the caller's emotional stress state. Method: The study was a retrospective and observational study of OHCA emergency call recordings from the Capital Region of Denmark. Callers were evaluated by five raters using a simplified emotional content and cooperation score (ECCS). Results: 894 call were included of which 250 callers were registered as emotional stressed. We found a significantly longer time from recognition of OHCA until first chest compression delivered in the emotional stressed callers vs. the not emotional stressed callers (65 s vs.38 s; P < 0.001). There was no significant difference in time from recognition of OHCA until initiation of CPR-instructions (P = 0.12). Furthermore, there was a significant higher incidence of the medical dispatcher being assertive and encouraging when instructing, and of the medical dispatcher instructing on speed and depth of chest compressions in calls with an emotional stressed caller (P = 0.006, P < 0.001 and P < 0.001). Conclusion: The emotional stressed callers had a significantly longer time from recognition of OHCA by the medical dispatcher until first chest compression was delivered. In addition, the quality of DA-CPR instructions given was significantly higher in the emotional stressed group. Conflict of interest: None. Funding: None.
