Abstract

Purpose: The aim of this study was to investigate the feasibility of an intelligent handheld ultrasound (US) device for assisting non-expert general practitioners (GPs) in detecting carotid plaques (CPs) in community populations.

Methods: This prospective parallel controlled trial recruited 111 consecutive community residents. All of them underwent examinations by non-expert GPs and specialist doctors using handheld US devices (setting A, setting B, and setting C). The results of setting C with specialist doctors were considered the gold standard. Carotid intima-media thickness (CIMT) and the features of CPs were measured and recorded. The diagnostic performance of GPs in distinguishing CPs was evaluated using a receiver operating characteristic curve. Inter-observer agreement was compared using the intragroup correlation coefficient (ICC). Questionnaires were completed to evaluate clinical benefits.

Results: Among the 111 community residents, 80, 96, and 112 CPs were detected in settings A, B, and C, respectively. Setting B exhibited better diagnostic performance than setting A for detecting CPs (area under the curve, 0.856 vs. 0.749; P<0.01). Setting B had better consistency with setting C than setting A in CIMT measurement and the assessment of CPs (ICC, 0.731 to 0.923). Moreover, measurements in setting B required less time than the other two settings (44.59 seconds vs. 108.87 seconds vs. 126.13 seconds, both P<0.01).

Conclusion: Using an intelligent handheld US device, GPs can perform CP screening and achieve a diagnostic capability comparable to that of specialist doctors.

智能手持式超声提高非专业全科医生在社区人群颈动脉检查中的能力:一项前瞻性平行对照试验。
目的:本研究的目的是探讨智能手持式超声(US)设备在协助非专业全科医生(gp)检测社区人群颈动脉斑块(CPs)的可行性。方法:前瞻性平行对照试验招募111名连续社区居民。他们都接受了非专业全科医生和专科医生使用手持美国设备(设置A,设置B和设置C)的检查。设置C与专科医生的结果被认为是金标准。测量并记录颈动脉内膜-中膜厚度(CIMT)和CPs特征。利用受者工作特征曲线评估全科医生在区分CPs方面的诊断性能。使用组内相关系数(ICC)比较观察者间的一致性。完成问卷以评估临床益处。结果:在111名社区居民中,分别在A、B和C环境中检测到80、96和112名CPs。设置B对cp的诊断效果优于设置A(曲线下面积,0.856比0.749;术中,0.01)。设置B与设置C在CIMT测量和CPs评价上的一致性优于设置A (ICC, 0.731 ~ 0.923)。此外,设置B的测量所需的时间比其他两个设置(44.59秒vs. 108.87秒vs. 126.13秒,均为P<;0.01)。结论:使用智能手持美国设备,全科医生可以进行CP筛查,并达到与专科医生相当的诊断能力。

期刊介绍: Ultrasonography, the official English-language journal of the Korean Society of Ultrasound in Medicine (KSUM), is an international peer-reviewed academic journal dedicated to practice, research, technology, and education dealing with medical ultrasound. It is renamed from the Journal of Korean Society of Ultrasound in Medicine in January 2014, and published four times per year: January 1, April 1, July 1, and October 1. Original articles, technical notes, topical reviews, perspectives, pictorial essays, and timely editorial materials are published in Ultrasonography covering state-of-the-art content. Ultrasonography aims to provide updated information on new diagnostic concepts and technical developments, including experimental animal studies using new equipment in addition to well-designed reviews of contemporary issues in patient care. Along with running KSUM Open, the annual international congress of KSUM, Ultrasonography also serves as a medium for cooperation among physicians and specialists from around the world who are focusing on various ultrasound technology and disease problems and relevant basic science.
