Abstract：
BACKGROUND: Timely dispatch of appropriate emergency medical services (EMS) resources to the scene of medical incidents, and/or provision of treatment at the scene by bystanders and medical emergency lay callers (referred to as \'callers\' in this review) can improve patient outcomes. Currently, in dispatch systems worldwide, prioritisation of dispatch relies mostly on verbal telephone information from callers, but advances in mobile phone technology provide means for sharing video footage. This scoping review aimed to map and identify current uses, opportunities, and challenges for using video livestreaming from callers\' smartphones to emergency medical dispatch centres.
METHODS: A scoping review of relevant published literature between 2007 and 2023 in the English language, searched within MEDLINE; CINAHL and PsycINFO, was descriptively synthesised, adhering to the PRISMA extension for scoping reviews.
RESULTS: Twenty-four articles remained from the initial search of 1,565 articles. Most studies were simulation-based and focused on emergency medical dispatchers\' (referred to as \'dispatcher/s\' in this review) assisted video cardiopulmonary resuscitation (CPR), predominantly concerned with measuring how video impacts CPR performance. Nine studies were based on real-life practice. Few studies specifically explored experiences of dispatchers or callers. Only three articles explored the impact that using video had on the dispatch of resources. Opportunities offered by video livestreaming included it being: perceived to be useful; easy to use; reassuring for both dispatchers and callers; and informing dispatcher decision-making. Challenges included the potential emotional impact for dispatchers and callers. There were also concerns about potential misuse of video, although there was no evidence that this was occurring. Evidence suggests a need for appropriate training of dispatchers and video-specific dispatch protocols.
CONCLUSIONS: Research is sparse in the context of video livestreaming. Few studies have focussed on the use of video livestreaming outside CPR provision, such as for trauma incidents, which are by their nature time-critical where visual information may offer significant benefit. Further investigation into acceptability and experience of the use of video livestreaming is warranted, to understand the potential psychological impact on dispatchers and callers.

摘要：
背景：及时向医疗事故现场派遣适当的紧急医疗服务（EMS）资源，和/或由旁观者和医疗急救外行来电者(在本综述中称为“来电者”)在现场提供治疗可以改善患者预后。目前,在世界各地的调度系统中，调度的优先级主要依赖于呼叫者的口头电话信息，但是手机技术的进步提供了分享视频片段的手段。这项范围审查旨在绘制和确定当前的用途，机遇,以及使用从呼叫者智能手机到紧急医疗调度中心的视频直播的挑战。
方法：对2007年至2023年英语中相关已发表文献的范围审查，在MEDLINE、CINAHL和PsycINFO中搜索，被描述性地合成，坚持PRISMA扩展范围审查。
结果：从1,565篇文章的初始搜索中剩下24篇文章。大多数研究都是基于模拟的，重点是紧急医疗调度员（在本综述中称为“调度员”）辅助视频心肺复苏（CPR），主要关注测量视频如何影响CPR表现。九项研究基于现实生活中的实践。很少有研究专门探讨调度员或呼叫者的经验。只有三篇文章探讨了使用视频对资源分配的影响。视频直播提供的机会包括：被认为有用；易于使用；让调度员和呼叫者放心；并告知调度员的决策。挑战包括对调度员和呼叫者的潜在情感影响。还有人担心视频可能被滥用，尽管没有证据表明这种情况正在发生。有证据表明，需要对调度员进行适当的培训和针对视频的调度协议。
结论：在视频直播的背景下，研究很少。很少有研究集中在使用CPR以外的视频直播，比如创伤事件，它们本质上是时间关键的，视觉信息可能会提供显著的好处。有必要对使用视频直播的可接受性和经验进行进一步调查，了解对调度员和来电者的潜在心理影响。
