Abstract

Objective: The aim of this study was to determine the extent of agreement on the measured echographic ejection fraction measured by emergency medicine (EM) residents compared with a cardiologist. Materials and Methods: This study was conducted with cardiac patients admitted to a hospital emergency department in Tehran, Iran. A total of 156 patient cases were reviewed. A group of trained EM residents evaluated the ejection fraction (EF) of these patients utilizing three different methods: Simpson’s method (N = 50), E-Point Septal Separation (EPSS, N = 56), and a visual technique (N = 50). A final assessment was made for all patients by a cardiologist. Results: In 69.3% of these patient cases, there was a significant correlation between the EM residents’ report and the cardiologists, with Cohen’s Kappa coefficient of .746 (P < .001). The Kappa coefficient for the visual technique, Simpson’s method, and EPSS was .697, .467, and .487, respectively. The sensitivity, specificity, positive and negative predictive values of EF measurements, provided by the EM residents, were 0.89%, 64.2%, 81.6%, and 76.5% compared with the cardiologist, respectively. Conclusion: This description study was done to determine the agreement of echocardiographic measurement of EF, assessed by trained EM residents, compared with a cardiologist’s review. In this case, the results demonstrated moderate to good agreement.

确定急诊住院医师与心脏病专家在超声射血分数测定上的一致程度

目的:本研究的目的是确定在测量超声射血分数的程度上，由急诊医学(EM)居民与心脏病专家进行比较。材料和方法:本研究在伊朗德黑兰一家医院急诊科收治的心脏病患者中进行。共回顾了156例患者病例。一组训练有素的急诊住院医师使用三种不同的方法评估这些患者的射血分数(EF):辛普森法(N = 50)， e点间隔分离(EPSS, N = 56)和视觉技术(N = 50)。一名心脏病专家对所有患者进行了最终评估。结果:在69.3%的病例中，急诊住院医师报告与心内科医师之间存在显著相关性，Cohen’s Kappa系数为0.746 (P < 0.001)。目视法、辛普森法和EPSS的Kappa系数分别为0.697、0.467和0.487。EM居民提供的EF测量的敏感性、特异性、阳性和阴性预测值与心脏病专家相比分别为0.89%、64.2%、81.6%和76.5%。结论:这项描述性研究是为了确定超声心动图测量EF的一致性，由训练有素的急诊住院医师评估，与心脏病专家的审查相比较。在这种情况下，结果显示中等到良好的一致性。
