TRIM: What Triage Model Is Safest And Most Effective For The Management Of 999 Callers With Suspected COVID-19? A Linked Outcome Study

在冠状病毒大流行期间，与COVID-19相关的999紧急救护车呼叫在不同时间点大幅增加。在某些情况下，电话量增加了两倍。救护车服务无法在合理的时间内将救护车送到每个呼叫者，也不是每个疑似COVID-19的患者都可以被送往医院。如果正确的病人没有被送到救护车或留在家里，他们可能会受到伤害甚至死亡。但是，如果每个病人都被送往医院，急诊科和住院服务可能会不堪重负，无法科普。救护车服务使用不同的模式来分类-或分流-呼叫者，但人们对什么样的分流模式在大流行期间最安全有效知之甚少。我们将比较2020年疫情期间救护车服务在呼叫中心和现场采用不同分流模式治疗的患者的结果。我们将从NHS数据集中检索这些结果，包括死亡数据;医院和国际电联的入院人数;急诊就诊人数;以及COVID-19诊断。我们将采访卫生服务人员，以了解他们的经历和担忧。我们将迅速提供调查结果，以帮助实施最佳模式，对999名疑似COVID-19症状的来电者进行分类和治疗。

999 emergency ambulance calls related to COVID-19 have increased enormously at various points during the coronavirus pandemic. On some occasions, the volume of calls has tripled. Ambulance services cannot send an ambulance to every caller within a reasonable timeframe and not every patient with suspected COVID-19 can be taken to hospital. If the right patients are not sent an ambulance or are left at home, they could suffer harm or even death. But, if every patient is taken to hospital, Emergency Department and inpatient services may be overwhelmed and unable to cope. Ambulance services use different models to sort out - or triage - callers, but little is known about what model of triage works most safely and effectively during a pandemic. We will compare outcomes for patients treated using different triage models employed by ambulance services in call centres and on scene during the 2020 pandemic. We will retrieve these outcomes from NHS datasets, including data on deaths; hospital and ITU admissions; Emergency Department attendances; and COVID-19 diagnosis.We will interview health service staff to understand experiences and concerns. We will deliver findings quickly to help implement the best model for sorting and treating 999 callers with suspected COVID-19 symptoms.
