Assessing medical students on core skills related to melanoma detection is challenging in the absence of a well-developed instrument.
We sought to develop an objective structured clinical examination for the detection and evaluation of melanoma among medical students.
This was a prospective cohort analysis of student and objective rater agreement on performance of clinical skills and assessment of differences in performance across 3 schools.
Kappa coefficients indicated excellent agreement for 3 of 5 core skills including commenting on the presence of the moulage (k = 0.87, 95% confidence interval 0.77-0.96), obtaining a history for the moulage (k = 0.84, 95% confidence interval 0.74-0.94), and making a clinical impression (k = 0.80, 95% confidence interval 0.68-0.92). There were no differences in performance across schools with respect to 3 of 5 core skills: commenting on the presence of the moulage (P = .15), initiating a history (P = .53), and managing the suspicious lesion (P value range .07-.17). Overall, 54.2% and 44.7% of students commented on the presence of the moulage and achieved maximum performance of core skills, respectively, with no difference in performance across schools.
Limitations include overall sample size of students and schools.
The Skin Cancer Objective Structured Clinical Examination represents a potentially important instrument to measure students' performance on the optimal step-by-step evaluation of a melanoma.
在缺乏完善工具的情况下,评估医学生与黑色素瘤检测相关的核心技能具有挑战性。
我们旨在为医学生开发一种用于检测和评估黑色素瘤的客观结构化临床检查。
这是一项对学生和客观评估者在临床技能表现上的一致性,以及在 3 所学校之间的表现差异的前瞻性队列分析。
Kappa 系数表明,在 5 项核心技能中的 3 项上具有出色的一致性,包括对模拟病变存在的评论(κ=0.87,95%置信区间 0.77-0.96)、获取模拟病变病史(κ=0.84,95%置信区间 0.74-0.94)和做出临床印象(κ=0.80,95%置信区间 0.68-0.92)。在 5 项核心技能中,有 3 项技能在 3 所学校之间的表现没有差异:对模拟病变存在的评论(P=0.15)、启动病史(P=0.53)和处理可疑病变(P 值范围 0.07-0.17)。总体而言,分别有 54.2%和 44.7%的学生对模拟病变的存在进行了评论,并达到了核心技能的最高表现,而学校之间的表现没有差异。
研究的局限性包括学生和学校的总体样本量。
皮肤癌客观结构化临床检查代表了一种潜在的重要工具,可以衡量学生对黑色素瘤进行最佳逐步评估的表现。
