摘要

背景:即时超声(POCUS)在多种内科、外科和产科疾病的及时识别和管理中发挥着重要作用。2013年为肯尼亚农村初级保健提供者制定了POCUS培训方案。该计划面临的一个重大挑战是获得价格合理的超声机器,具有足够的图像质量和传输图像以进行远程审查的能力。本研究的目的是比较智能手机连接的手持式超声与传统超声设备的效用,由肯尼亚训练有素的医疗保健提供者进行图像采集和解释。方法:本研究在对已经接受过POCUS培训的医疗保健提供者进行常规再培训和测试期间进行。测试环节包括当地验证的观察结构化临床考试(OSCE),评估受训人员在创伤超声扩展重点评估(E-FAST)和重点产科检查方面的技能。每个受训者都进行了两次OSCE检查,一次使用智能手机连接的手持超声,一次使用笔记本超声模型。结果:5名学员共获得120张图像,并对图像质量和解译进行评分。笔记本超声的整体E-FAST成像质量得分明显高于手持超声,但在图像解释方面无显著差异。两种超声系统的总体聚焦产科图像质量和图像解释评分相同。当被分为单独的E-FAST和集中的产科视图时,两种超声系统在图像质量或图像解释评分方面没有统计学上的显著差异。使用手持超声获得的图像通过本地3g手机网络上传到相关的云存储。结论:在肯尼亚农村POCUS受训者中,发现手持式超声在聚焦产科图像质量、聚焦产科图像解释和E-FAST图像解释方面不低于传统笔记本超声。然而,手持式超声被发现在E-FAST图像质量上较差。当分别评估每个E-FAST和重点产科视图时,没有观察到这些差异。手持式超声允许快速图像传输用于远程检查。

Utility of hand-held ultrasound for image acquisition and interpretation by trained Kenyan providers.

Utility of hand-held ultrasound for image acquisition and interpretation by trained Kenyan providers.

Background: Point-of-care ultrasound (POCUS) plays a prominent role in the timely recognition and management of multiple medical, surgical, and obstetric conditions. A POCUS training program for primary healthcare providers in rural Kenya was developed in 2013. A significant challenge to this program is the acquisition of reasonably priced ultrasound machines with adequate image quality and the ability to transmit images for remote review. The goal of this study is to compare the utility of a smartphone-connected, hand-held ultrasound with a traditional ultrasound device for image acquisition and interpretation by trained healthcare providers in Kenya.

Methods: This study took place during a routine re-training and testing session for healthcare providers who had already received POCUS training. The testing session involved a locally validated Observed Structured Clinical Exam (OSCE) that assessed trainees' skills in performing the Extended Focused Assessment with Sonography for Trauma (E-FAST) and focused obstetric exams. Each trainee performed the OSCE twice, once using a smartphone-connected hand-held ultrasound and once using their notebook ultrasound model.

Results: Five trainees obtained a total of 120 images and were scored on image quality and interpretation. Overall E-FAST imaging quality scores were significantly higher for the notebook ultrasound compared to the hand-held ultrasound but there was no significant difference in image interpretation. Overall focused obstetric image quality and image interpretation scores were the same for both ultrasound systems. When separated into individual E-FAST and focused obstetric views, there were no statistically significant differences in the image quality or image interpretation scores between the two ultrasound systems. Images obtained using the hand-held ultrasound were uploaded to the associated cloud storage using a local 3G-cell phone network. Upload times were 2-3 min.

Conclusion: Among POCUS trainees in rural Kenya, the hand-held ultrasound was found to be non-inferior to the traditional notebook ultrasound for focused obstetric image quality, focused obstetric image interpretation, and E-FAST image interpretation. However, hand-held ultrasound use was found to be inferior for E-FAST image quality. These differences were not observed when evaluating each E-FAST and focused obstetric views separately. The hand-held ultrasound allowed for rapid image transmission for remote review.
