Reducing the time to treatment by means of cardiopulmonary resuscitation (CPR) and defibrillation is essential to increasing survival after cardiac arrest. A novel method of dispatching drones for delivery of automated external defibrillators (AEDs) to the site of a suspected out-of-hospital cardiac arrest (OHCA) has been shown to be feasible, with the potential to shorten response times compared with the emergency medical services. However, little is known of dispatchers' experiences of using this novel methodology.
A qualitative semi-structured interview study with a phenomenological approach was used. Ten registered nurses employed at an emergency medical dispatch centre in Gothenburg, Sweden, were interviewed and the data was analysed by qualitative content analysis. The purpose was to explore dispatcher nurses' experiences of deliveries of AEDs by drones in cases of suspected OHCA.
Three categories were formed. Nurses expressed varying compliance to the telephone-assisted protocol for dispatch of AED-equipped drones. They experienced uncertainty as to how long would be an acceptable interruption from the CPR protocol in order to retrieve a drone-delivered AED. The majority experienced that collegial support was important. Technical support, routines and training need to be improved to further optimise action in cases of drone-delivered AEDs handled by dispatcher nurses.
Although telephone-assisted routines for drone dispatch in cases of OHCA were available, their use was rare. Registered nurses showed variable degrees of understanding of how to comply with these protocols. Collegial and technical support was considered important, alongside routines and training, which need to be improved to further support bystander use of drone-delivered AEDs. As the possibilities of using drones to deliver AEDs in cases of OHCA are explored more extensively globally, there is a good possibility that this study could be of benefit to other nations implementing similar methods. We present concrete aspects that are important to take into consideration when implementing this kind of methodology at dispatch centres.
通过心肺复苏术 (CPR) 和除颤来缩短治疗时间对于提高心搏骤停后的生存率至关重要。一项新的派遣无人机向疑似院外心搏骤停 (OHCA) 现场运送自动体外除颤器 (AED) 的方法已被证明是可行的，与紧急医疗服务相比，这种方法有可能缩短反应时间。然而，对于调度员使用这种新方法的经验知之甚少。
采用现象学方法的定性半结构式访谈研究。采访了瑞典哥德堡一家紧急医疗调度中心的 10 名注册护士，采用定性内容分析法对数据进行分析。目的是探讨调度员护士在疑似 OHCA 病例中使用无人机配送 AED 的经验。
形成了三个类别。护士对 AED 配备的无人机电话协助配送协议的遵守程度存在差异。他们对在取回无人机配送的 AED 时中断 CPR 协议多长时间不确定。大多数人认为同事的支持很重要。需要改进技术支持、常规和培训，以进一步优化调度员护士处理无人机配送 AED 的行动。
尽管有针对 OHCA 情况下无人机调度的电话协助程序，但很少使用。注册护士对如何遵守这些协议的理解程度存在差异。同事和技术支持被认为很重要，同时还需要改进常规和培训，以进一步支持旁观者使用无人机配送的 AED。随着在全球范围内更广泛地探索使用无人机在 OHCA 情况下运送 AED 的可能性，本研究有可能对其他实施类似方法的国家有所裨益。我们提出了在调度中心实施这种方法时需要考虑的具体方面。
