BACKGROUND Dispatch services (DS's) form an integral part of emergency medical service (EMS) systems. The role of a dispatcher has also evolved into a crucial link in patient care delivery, particularly in dispatcher assisted cardio-pulmonary resuscitation (DACPR) during out-of-hospital cardiac arrest (OHCA). Yet, there has been a paucity of research into the emerging area of dispatch science in Asia. This paper compares the characteristics of DS's, and state of implementation of DACPR within the Pan-Asian Resuscitation Outcomes (PAROS) network. METHODS A cross-sectional descriptive survey addressing population characteristics, DS structures and levels of service, state of DACPR implementation (including protocols and quality improvement programs) among PAROS DS's. RESULTS 9 DS's responded, representing a total of 23 dispatch centres from 9 countries that serve over 80 million people. Most PAROS DS's operate a tiered dispatch response, have implemented medical oversight, and tend to be staffed by dispatchers with a predominantly medical background. Almost all PAROS DS's have begun tracking key EMS indicators. 77.8% (n = 7) of PAROS DS's have introduced DACPR. Of the DS's that have rolled out DACPR, 71.4% (n = 5) provided instructions in over one language. All DS's that implemented DACPR and provided feedback to dispatchers offered feedback on missed OHCA recognition. The majority of DS's (83.3%; n = 5) that offered DACPR and provided feedback to dispatchers also implemented corrective feedback, while 66.7% (n = 4) offered positive feedback. Compression-only CPR was the standard instruction for PAROS DS's. OHCA recognition sensitivity varied widely in PAROS DS's, ranging from 32.6% (95% CI: 29.9-35.5%) to 79.2% (95% CI: 72.9-84.4%). Median time to first compression ranged from 120 s to 220 s. CONCLUSIONS We found notable variations in characteristics and state of DACPR implementation between PAROS DS's. These findings will lay the groundwork for future DS and DACPR studies in the PAROS network.

泛亚国家/地区的紧急医疗调度服务：基于网络的调查。

背景技术调度服务（DS）形成紧急医疗服务（EMS）系统的组成部分。调度员的作用也已演变成患者护理服务中的关键环节，尤其是在院外心脏骤停（OHCA）期间由调度员辅助的心肺复苏（DACPR）中。然而，对于亚洲派遣科学新兴领域的研究很少。本文比较了DS的特性以及泛亚复苏成果（PAROS）网络中DACPR的实施状态。方法一项横断面描述性调查，涉及PAROS DS的人群特征，DS结构和服务水平，DACPR实施状态（包括协议和质量改进计划）。结果9 DS做出了回应，代表9个国家/地区的23个调度中心，为8000万人提供服务。大多数PAROS DS的操作都是分层的响应，已经执行了医疗监督，并且往往由具有主要医学背景的调度员来担任。几乎所有PAROS DS都已开始跟踪关键EMS指标。77.8％（n = 7）的PAROS DS引入了DACPR。在已推出DACPR的DS中，有71.4％（n = 5）以一种以上的语言提供了说明。所有实施DACPR并向调度员提供反馈的DS都提供了有关OHCA识别缺失的反馈。DS的大多数（83.3％； n = 5）提供DACPR并向调度员提供反馈，也实施了纠正性反馈，而66.7％（n = 4）提供了正反馈。仅压缩CPR是PAROS DS的标准说明。OHCA识别灵敏度在PAROS DS中差异很大，范围从32.6％（95％CI：29.9-35.5％）到79.2％（95％CI：72.9-84.4％）。第一次压缩的中值时间为120 s至220 s。结论我们发现PAROS DS的DACPR实现的特性和状态存在显着差异。这些发现将为将来在PAROS网络中进行DS和DACPR研究奠定基础。
