Abstract

Stroke is a devastating condition with significant societal and personal costs. Attempts to improve outcomes have increasingly focussed on improvements in prehospital care of these patients. This study aims to provide an epidemiologic profile of stroke presentations to an ambulance service. A descriptive quantitative analysis of linked administrative and clinical patient data across prehospital, hospital, and death records from a two-year period (2016–2017), was used to profile the acute stroke cohort transported by ambulance in Queensland, Australia. The epidemiologic profile of patients and sub-type of stroke is presented. There were 17,603 presentations of suspected acute stroke in Queensland during the study period amongst 2,078,140 ambulance responses. A total of 11,578 patients had a confirmed diagnosis of stroke at the time of their final discharge. Of this population 49.8% suffered an Acute Ischaemic Stroke, 12.9% had intracerebral haemorrhage, 4.5% had subarachnoid haemorrhage and 32.8% were transient ischaemic attack. Of those with acute ischaemic stroke (AIS) 9.2% were due to a large vessel occlusion. The three-month stroke related fatality rate was 10%. This study demonstrated a lower annual presentation rate of stroke, to an emergency ambulance service, than would be expected based on population studies while the overall mortality rate amongst this population was higher. The reasons for these differences warrant further investigation.
紧急救护服务中急性中风的流行病学研究
脑卒中是一种破坏性疾病,会给社会和个人带来巨大损失。为改善治疗效果,人们越来越重视改善对这些患者的院前护理。本研究旨在提供救护车服务中卒中患者的流行病学概况。通过对两年内(2016-2017 年)院前、医院和死亡记录中相关联的行政和临床患者数据进行描述性定量分析,对澳大利亚昆士兰州由救护车转运的急性中风患者群体进行了剖析。本文介绍了患者的流行病学概况和中风的亚型。研究期间,昆士兰共接诊 2,078,140 例疑似急性中风患者,其中有 17,603 例。共有 11,578 名患者在最后出院时确诊为中风。其中 49.8% 患有急性缺血性中风,12.9% 患有脑内出血,4.5% 患有蛛网膜下腔出血,32.8% 患有短暂性脑缺血发作。在急性缺血性中风(AIS)患者中,9.2%是因为大血管闭塞。三个月内与中风相关的死亡率为 10%。这项研究表明,每年向紧急救护服务部门报告的中风发病率低于人口研究的预期,而这一人群的总死亡率却较高。造成这些差异的原因值得进一步研究。
