简要总结
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.
详细描述
Background:
Emergency Medical Communication Centres (EMCCs) in Norway receive more than 400 000 emergency calls every year, resulting in more than 250 000 ambulance dispatches. Emergency calls are answered by nurses or paramedics with special training, who by audio assesses the situation and decides on a response. Video streaming as a supplement to telephone in EMCC was introduced during springtime 2020 in Norway, and is independent of this study. The intended effect was to improve shared situational awareness between caller and operator, and thus improve the triage process. The video solution is live-only, and caller must give consent. Limited scientific evidence for such use exists, and even if video calls seems commonplace in society, the effects and acceptance in EMCCs has mainly been studied in simulated settings. Preliminary results from the early launch of video streaming showed that injured patients was one of the conditions where the dispatchers seemed to find video streaming useful. Previous studies by Bakke et.al investigating bystander first aid for injured patients, showed a potential for dispatchers in EMCCs to recognize more injured patients with the need for bystander first aid.
Aim:
This study focuses on the effect of video streaming in EMCCs on bystander first aid. The investigators aim to investigate whether dispatchers identifies the need for relevant first aid measures more frequently when using video streaming. The study will be conducted in several health trusts in Norway. In health trusts where video streaming not yet has been implemented in the EMCC, the investigators will collect data from period before video streaming is implemented, and after video streaming is implemented. From some health trusts in the study, video streaming already been implemented, and data collection will hence only be conducted for an after-period.
