Historically, testing medical students' skills using a handheld ophthalmoscope has been difficult to do objectively. Many programs train students using plastic models of the eye which are a very limited fidelity simulator of a real human eye. This makes it difficult to be sure that actual proficiency is attained given the differences between the various models and actual patients. The purpose of this article is to introduce a method of testing where a medical student must match a patient with his/her fundus photo, ensuring objective evaluation as well as developing skills on real patients which are more likely to transfer into clinical practice directly.
Fundus photos from standardized patients (SPs) were obtained using a retinal camera and placed into a grid using proprietary software. Medical students were then asked to examine a SP and attempt to match the patient to his/her fundus photo in the grid.
Of the 33 medical students tested, only 10 were able to match the SP's eye to the correct photo in the grid. The average time to correct selection was 175 seconds, and the successful students rated their confidence level at 27.5% (average). The incorrect selection took less time, averaging 118 seconds, yet yielded a higher student-reported confidence level at 34.8% (average). The only noteworthy predictor of success (<0.05) was the student's age (=0.02).
It may be determined that there is an apparent gap in the ophthalmoscopy training of the students tested. It may also be of concern that students who selected the incorrect photo were more confident in their selections than students who chose the correct photo. More training may be necessary to close this gap, and future studies should attempt to establish continuing protocols in multiple centers.
从历史上看,使用手持检眼镜客观地测试医学生的技能一直很困难。许多项目使用眼睛的塑料模型来培训学生,而这些模型对真实人眼的模拟逼真度非常有限。鉴于各种模型与实际患者之间存在差异,这使得很难确定学生是否真正掌握了实际技能。本文的目的是介绍一种测试方法,让医学生将患者与他/她的眼底照片进行匹配,以确保客观评估,并培养在真实患者身上的技能,这些技能更有可能直接转化为临床实践。
使用视网膜相机获取标准化患者(SP)的眼底照片,并使用专有软件将其放入网格中。然后要求医学生检查一名SP,并尝试在网格中找到与该患者匹配的眼底照片。
在接受测试的33名医学生中,只有10人能够将SP的眼睛与网格中的正确照片匹配。正确选择的平均时间为175秒,成功的学生将他们的信心水平评为27.5%(平均)。错误选择花费的时间较少,平均为118秒,但学生报告的信心水平更高,为34.8%(平均)。唯一值得注意的成功预测因素(<0.05)是学生的年龄(=0.02)。
可以确定,接受测试的学生在检眼镜检查培训方面存在明显差距。同样值得关注的是,选择错误照片的学生比选择正确照片的学生对自己的选择更有信心。可能需要更多培训来弥合这一差距,未来的研究应尝试在多个中心建立持续的方案。
