Video emergency calls (VCs) represent a feasible future trend in medical dispatching. Acceptance among callers and dispatchers seems to be good. Indications, potential problems, limitations, and directions of research of adding a live video from smartphones to an emergency call have not been reviewed outside the context of out-of-hospital cardiac arrest (OHCA).
The main objective of this study is to examine the scope and nature of research publications on the topic of VC. The secondary goal is to identify research gaps and discuss the potential directions of research efforts of VC.
Following PRISMA-ScR guidelines, online bibliographic databases PubMed, Web of Science, SCOPUS, Google Scholar, ClinicalTrials.gov, and gray literature were searched from the period of January 1, 2012 through March 1, 2022 in English. Only studies focusing on video transfer via mobile phone to emergency medical dispatch centers (EMDCs) were included.
Twelve articles were included in the qualitative synthesis and six main themes were identified: (1) cardiopulmonary resuscitation (CPR) guided by VC; (2) indications of VCs; (3) dispatchers' feedback and perception; (4) technical aspects of VCs; (5) callers' acceptance; and (6) confidentiality and legal issues.
Video emergency calls are feasible and seem to be a well-accepted auxiliary method among dispatchers and callers. Some promising clinical results exist, especially for video-assisted CPR. On the other hand, there are still enormous knowledge gaps in the vast majority of implementation aspects of VC into practice.
视频紧急呼叫（VC）代表了医疗调度的未来可行趋势。呼叫者和调度员的接受程度似乎很好。在院外心脏骤停（OHCA）之外，尚未在智能手机上添加实时视频到紧急呼叫的指示、潜在问题、局限性和研究方向方面进行综述。
本研究的主要目的是检查有关 VC 主题的研究出版物的范围和性质。次要目标是确定研究空白，并讨论 VC 研究工作的潜在方向。
根据 PRISMA-ScR 指南，从 2012 年 1 月 1 日至 2022 年 3 月 1 日，使用英语在在线书目数据库 PubMed、Web of Science、SCOPUS、Google Scholar、ClinicalTrials.gov 和灰色文献中进行了搜索。仅包括专注于通过手机向紧急医疗调度中心（EMDC）传输视频的研究。
有 12 篇文章被纳入定性综合分析，确定了 6 个主要主题：（1）VC 指导的心肺复苏术（CPR）；（2）VC 的适应症；（3）调度员的反馈和感知；（4）VC 的技术方面；（5）呼叫者的接受度；（6）保密性和法律问题。
视频紧急呼叫是可行的，并且似乎在调度员和呼叫者中是一种被广泛接受的辅助方法。存在一些有前途的临床结果，特别是对于视频辅助 CPR。另一方面，在将 VC 实施到实践的绝大多数方面仍然存在巨大的知识空白。
