Obtaining accurate information from a 112 caller is key to correct tasking of Helicopter Emergency Medical Services (HEMS). Being able to view the incident scene via video from a mobile phone may assist HEMS dispatch by providing more accurate information such as mechanism of injury and/or injuries sustained. The objective of this study is to describe the acceptability and feasibility of using live video footage from the mobile phone of a 112 caller as an HEMS dispatch aid.
Live footage is obtained via the 112 caller's mobile phone camera through the secure GoodSAM app's Instant-on-scene™ platform. Video footage is streamed directly to the dispatcher, and not stored. During the feasibility trial period, dispatchers noted the purpose for which they used the footage and rated ease of use and any technical- and operational issues they encountered. A subjective assessment of caller acceptance to use video was conducted.
Video footage from scene was attempted for 21 emergency calls. The leading reasons listed by the dispatchers to use live footage were to directly assess the patient (18/21) and to obtain information about the mechanism of injury and the scene (11/21). HEMS dispatchers rated the ease of use with a 4.95 on a 5-point scale (range 4-5). All callers gave permission to stream from their telephone camera. Video footage from scene was successfully obtained in 19 calls, and was used by the dispatcher as an aid to send (5) or stand down (14) a Helicopter Emergency Medical Services team.
Live video footage from a 112 caller can be used to provide dispatchers with more information from the scene of an incident and the clinical condition of the patient(s). The use of mobile phone video was readily accepted by the 112 caller and the technology robust. Further research is warranted to assess the impact video from scene could have on HEMS dispatching.
从 112 报警电话中获取准确信息是正确派遣直升机紧急医疗服务（HEMS）的关键。能够通过手机视频查看事故现场，可能有助于 HEMS 调度，提供更准确的信息，如受伤机制和/或受伤情况。本研究的目的是描述使用 112 报警电话持有人的手机实时视频作为 HEMS 调度辅助工具的可接受性和可行性。
通过安全的 GoodSAM 应用程序的即时现场（Instant-on-scene™）平台，从 112 报警电话持有人的手机摄像头获取实时视频。视频直接传送给调度员，不存储。在可行性试验期间，调度员记录他们使用视频的目的，并对易用性和遇到的任何技术和操作问题进行评分。还对报警人使用视频的主观接受程度进行了评估。
尝试对 21 个紧急电话进行现场视频传输。调度员列出使用实时视频的主要原因是直接评估患者（21 个中的 18 个）和获取受伤机制和现场信息（21 个中的 11 个）。HEMS 调度员对易用性的评分在 5 分制中为 4.95（范围 4-5）。所有报警人都允许从他们的电话摄像头进行视频流传输。19 个电话成功获取了现场视频，调度员使用该视频辅助发送（5 个）或遣返（14 个）一个 HEMS 小组。
可以使用来自 112 报警电话持有人的实时视频为调度员提供更多来自事故现场和患者临床情况的信息。移动电话视频的使用得到了 112 报警人的认可，且技术可靠。需要进一步的研究来评估现场视频对 HEMS 调度的影响。
