在英国（UK）的第一波COVID-19大流行期间，描述紧急救护车服务的呼叫量和模式、救护车被派遣的呼叫比例、送往医院的比例以及所使用的分流特征。英国所有救护车服务的半结构化电子调查（n = 13）和22周（2020年2月1日至7月3日）每周呼叫量的常规服务数据请求。我们会通过电子邮件向首席执行官和研究负责人发送调查问卷和数据请求，然后通过电子邮件和电话提醒。常规资料采用描述性统计分析，问卷资料采用主题分析。从12个服务部门收到了已填写的调查表。不同服务的通话量差异很大，英国在第7周达到峰值，比基线高出13.1%（服务范围为-0.5%至+31.4%）。研究期结束时，所有服务的呼叫量均低于基线（服务范围为-3.7%至-25.5%）。英国各地的疑似COVID-19呼叫总数为604，146个（占所有呼叫的13.5%），服务之间存在很大差异（服务范围为3.7%至25.7%），服务峰值为11.4%至44.5%。在这些召唤中，有478，638宗（79.2%）获派救护车（服务范围为59.0%至100.0%），其中262，547宗（43.5%）被送往医院（服务范围为32.0%至53.9%）。分类模式在不同的服务和不同的时间。两个主要的呼叫分类系统在英国各地使用。有大量的产品和安排用于二级分类，使用护理人员，护士和医生来支持呼叫中心和现场的决策。分类程序经常发生变化。通话量变化很大。随着COVID-19呼叫取代其他呼叫，病例组合和工作量发生了显著变化。分诊模式和院前结果在不同的服务之间存在差异。我们迫切需要了解分流模式的安全性和有效性，以便在进一步的浪潮和流行病期间提供护理信息。
During the first wave of the COVID‐19 pandemic in the United Kingdom (UK), to describe volume and pattern of calls to emergency ambulance services, proportion of calls where an ambulance was dispatched, proportion conveyed to hospital, and features of triage used. Semistructured electronic survey of all UK ambulance services (n = 13) and a request for routine service data on weekly call volumes for 22 weeks (February 1–July 3, 2020). Questionnaires and data request were emailed to chief executives and research leads followed by email and telephone reminders. The routine data were analyzed using descriptive statistics, and questionnaire data using thematic analysis. Completed questionnaires were received from 12 services. Call volume varied widely between services, with a UK peak at week 7 at 13.1% above baseline (service range ‐0.5% to +31.4%). All services ended the study period with a lower call volume than at baseline (service range ‐3.7% to ‐25.5%). Suspected COVID‐19 calls across the UK totaled 604,146 (13.5% of all calls), with wide variation between services (service range 3.7% to 25.7%), and in service peaks of 11.4% to 44.5%. Ambulances were dispatched to 478,638 (79.2%) of these calls (service range 59.0% to 100.0%), with 262,547 (43.5%) resulting in conveyance to hospital (service range 32.0% to 53.9%). Triage models varied between services and over time. Two primary call triage systems were in use across the UK. There were a large number of products and arrangements used for secondary triage, with services using paramedics, nurses, and doctors to support decision making in the call center and on scene. Frequent changes to triage processes took place. Call volumes were highly variable. Case mix and workload changed significantly as COVID‐19 calls displaced other calls. Triage models and prehospital outcomes varied between services. We urgently need to understand safety and effectiveness of triage models to inform care during further waves and pandemics.
