Transmission of echocardiograms via telemedicine links has allowed remote hospitals direct access to pediatric cardiology subspecialty care. This study assessed the accuracy of echocardiogram interpretation across an integrated services digital network (ISDN) telemedicine link.
Telemedicine systems were installed between Cape Fear Valley Medical Center neonatal intensive care unit and University of North Carolina Hospitals. One board-certified pediatric cardiologist interpreted 105 full-length echocardiograms that were videotaped and then transmitted over the system. Six months later, the same cardiologist reinterpreted the 105 original videotape studies from the off-site hospital and results were compared with the interpretations of the transmitted data.
Interpretation of transmitted echocardiograms did not differ significantly from the original studies for diagnosis, evaluation of left ventricular function, valve function evaluation, and the presence of a ductus arteriosus. Minor differences in qualitative parameters were seen.
Transmission of full-length echocardiograms over the ISDN telemedicine link is comparable to videotape review. There was no loss of significant clinical information, and the minor discrepancies noted did not impact management decisions.
通过远程医疗链接传输超声心动图,使偏远医院能够直接获得儿科心脏病专科护理。本研究评估了通过综合服务数字网络(ISDN)远程医疗链接进行超声心动图解读的准确性。
在开普菲尔谷医疗中心新生儿重症监护病房和北卡罗来纳大学医院之间安装了远程医疗系统。一名获得董事会认证的儿科心脏病专家对105份完整的超声心动图进行解读,这些超声心动图被录像,然后通过该系统传输。六个月后,同一名心脏病专家对来自异地医院的105份原始录像研究进行重新解读,并将结果与传输数据的解读进行比较。
对于诊断、左心室功能评估、瓣膜功能评估以及动脉导管未闭的存在情况,传输的超声心动图解读与原始研究相比无显著差异。在定性参数方面存在细微差异。
通过ISDN远程医疗链接传输完整的超声心动图与录像审查相当。没有重大临床重要的临床信息丢失,并且所指出的细微差异不影响管理决策。
