NCT05121649

Brief Summary

Video streaming as an additional tool to telephone was introduced in some Norwegian emergency medical call centers during the spring of 2020. This allows the dispatchers to communicate with the caller through video streaming during emergency calls. Some studies are conducted on this use of video streaming, but further research is needed. In this study, the investigators have chosen to focus on potential effect from video streaming on bystander first aid for injured patients. The investigators have knowledge from preliminary results that dispatchers often find video streaming useful in emergency calls regarding injuries. This study will investigate whether the use of video streaming might have an effect on the recognition rate by dispatchers on the need for bystander first aid for injured patients. In addition, the investigators will investigate whether video-instructions from dispatcher can improve bystander first aid quality. The investigators will be using data collected by ambulance personnel including patients with injuries, as well as data from EMCC journals and audio logs.
