抽象的：
急诊科（ED）是51 - 82％的可预防医疗错误的地点，其中大多数是诊断错误。诊断错误是错过或无意间延迟的诊断。诊断错误导致医疗保健成本增加以及严重的患者发病率或死亡。beplay苹果手机能用吗研究诊断错误是有限的。事件报告系统被认为是识别主动和潜在错误的一种机制。该项目利用事件报告系统和医疗错误注册表来研究诊断错误。该项目的目的是确定与ED中诊断错误相关的患者遭遇元素，并分析这些诊断错误，以检测促成因素的趋势和关系。总共确定了90个互斥医疗错误的84例患者遭遇。诊断错误占错误的55％。最常见的患者应对元素是：成人患者，患者到达时间间隔为下午3点至下午6点，到达日：星期二，星期五或周日以及出院或ICU入院处置。 The identified contributing factors were grouped as system/process, cognitive or non-remediable factors. The predominant system/process contributing factors were high workloads, test or treatment processing delay, ineffective patient handoffs and lack of departmental policies regarding condition evaluation and management. The predominant cognitive contributing factors were faulty information processing and information verification while the non-remediable contributing factors were limited patient historians and atypical patient presentations. Though this project was subject to hindsight, recall and reporting biases, it demonstrated that the combination of a clinical incident reporting system, a revised incident review process and a descriptive medical error registry was a feasible method to monitor the frequency and trends of diagnostic errors in the ED and may suggest future areas to focus to patient safety interventions and research.
