This study uses an objective structured clinical examination to evaluate the performance and interpretation of the vascular physical examination by interns and medical students.
A patient with lower extremity arterial occlusive disease findings was examined by 20 third-year students (M3), 23 physicians entering surgical internship (PGY1), and 7 individuals completing internship (PGY2). The test consisted of two sections: part A evaluated the individuals' ability to perform a pulse examination (data gathering); part B evaluated the interpretation of the physical examination findings (data interpretation). National Board of Medical Examiners Part II examination results were obtained for 84% of participants.
All groups performed poorly, with overall correct percent scores being 43% (M3), 39% (PGY1), and 62% (PGY2). PGY2s performed significantly better than M3s or PGY1s (p = 0.0002). No statistical difference was noted between M3 and PGY1 scores. Overall, data gathering skills were significantly better than data interpretation skills (51% vs 37%, p = 0.0001). National Board of Medical Examiners Part II scores did not vary substantially among groups.
Interns and medical students demonstrated considerable inaccuracy in both data gathering and data interpretation. A modest improvement was observed in individuals tested at the end of the internship year. This study suggests that increased attention should be directed toward instructing surgical residents and students how to perform an accurate peripheral vascular physical examination and how to interpret its significance.
本研究采用客观结构化临床考试来评估实习生和医学生进行血管体格检查的表现及解读能力。
一名有下肢动脉闭塞性疾病表现的患者由20名三年级学生(M3)、23名即将开始外科实习的医生(PGY1)和7名完成实习的人员(PGY2)进行检查。测试包括两个部分:A部分评估个人进行脉搏检查的能力(数据收集);B部分评估体格检查结果的解读(数据解读)。84%的参与者获得了美国国家医学考试委员会第二部分考试的成绩。
所有组的表现都很差,总体正确百分比分数分别为43%(M3)、39%(PGY1)和62%(PGY2)。PGY2组的表现明显优于M3组或PGY1组(p = 0.0002)。M3组和PGY1组的分数之间未发现统计学差异。总体而言,数据收集技能明显优于数据解读技能(51%对37%,p = 0.0001)。美国国家医学考试委员会第二部分的分数在各组之间没有显著差异。
实习生和医学生在数据收集和数据解读方面都表现出相当大的不准确。在实习年度末接受测试的个体中观察到了适度的改善。本研究表明,应更加关注指导外科住院医师和学生如何进行准确的外周血管体格检查以及如何解读其意义。
