The Limit of Detection in the Emergency Department Trial: A stepped-wedge cluster randomised trial for rapid assessment of patients with suspected acute coronary syndrome in the Emergency Department

每年有超过45万名患者因胸痛而到澳大利亚急诊室就诊。目前为这些患者排除心脏病发作的方法是漫长的，昂贵的，并造成急诊室过度拥挤。在一个需求不断增长而资源有限的系统中，这是不可持续的。这项研究将评估一种快速评估途径，用于调查急诊科的胸痛。该途径将减少医疗保健利用率，同时保持患者安全。

Over 450,000 patients present to Australian emergency departments with chest pain every year. The current approach to rule out heart attack for these patients is lengthy, costly and creates overcrowding in the emergency department. This is not sustainable in a system with growing demand and finite resources. This study will evaluate a rapid assessment pathway for investigating chest pain in the emergency department. The pathway will reduce healthcare utilisation while retaining patient safety.
