The helicopter emergency services (HEMS) Benefit Score (HBS) is a nine-level scoring system developed to evaluate the benefits of HEMS missions. The HBS has been in clinical use for two decades in its original form. Advances in prehospital care, however, have produced demand for a revision of the HBS. Therefore, we developed the emergency medical services (EMS) Benefit Score (EBS) based on the former HBS. As reflected by its name, the aim of the EBS is to measure the benefits produced by the whole EMS systems to patients.
This is a four-round, web-based, international Delphi consensus study with a consensus definition made by experts from seven countries. Participants reviewed items of the revised HBS on a 5-point Likert scale. A content validity index (CVI) was calculated, and agreement was defined as a 70% CVI. Study included experts from seven European countries. Of these, 18 were prehospital expert panellists and 11 were in-hospital commentary board members.
The first Delphi round resulted in 1248 intervention examples divided into ten diagnostic categories. After removing overlapping examples, 413 interventions were included in the second Delphi round, which resulted in 38 examples divided into HBS categories 3-8. In the third Delphi round, these resulted in 37 prehospital interventions, examples of which were given revised version of the score. In the fourth and final Delphi round, the expert panel was given an opportunity to accept or comment on the revised scoring system.
The former HBS was revised by a Delphi methodology and EBS developed to represent its structural purpose better. The EBS includes 37 exemplar prehospital interventions to guide its clinical use. Trial registration The study permission was requested and granted by Turku University Hospital (decision number TP2/010/18).
直升机紧急医疗服务（HEMS）效益评分（HBS）是一个九级评分系统，旨在评估 HEMS 任务的效益。HBS 以原始形式在临床应用了二十年。然而，由于院前护理的进步，需要对 HBS 进行修订。因此，我们基于前 HBS 开发了紧急医疗服务（EMS）效益评分（EBS）。正如其名称所反映的，EBS 的目的是衡量整个 EMS 系统为患者带来的效益。
这是一个四轮、基于网络的、有七个国家专家参与的德尔菲共识研究，对共识进行了定义。参与者对修订后的 HBS 项目进行了 5 点李克特量表评分。计算内容有效性指数（CVI），并将 70%的 CVI 定义为一致性。研究包括来自七个欧洲国家的专家。其中，18 人是院前专家小组成员，11 人是院内评论委员会成员。
第一轮德尔菲研究结果将 1248 个干预实例分为十个诊断类别。在去除重叠实例后，第二轮德尔菲研究纳入了 413 个干预实例，分为 HBS 类别 3-8。在第三轮德尔菲研究中，这些干预实例分为 37 个院前干预实例，并给出了评分的修订版本。在第四轮也是最后一轮德尔菲研究中，专家小组有机会接受或评论修订后的评分系统。
通过德尔菲方法对前 HBS 进行了修订，并开发了 EBS，以更好地代表其结构目的。EBS 包括 37 个示例院前干预措施，以指导其临床应用。研究注册请求并获得了图尔库大学医院的许可（决定号 TP2/010/18）。
