Learner handover (LH), the process of sharing of information about learners between faculty supervisors, allows for longitudinal assessment fundamental in the competency-based education model. However, the potential to bias future assessments has been raised as a concern. The purpose of this study is to determine whether prior performance information such as LH influences the assessment of learners in the clinical context. Between December 2017 and June 2018, forty-two faculty members and final-year residents from the Department of Medicine at the University of Ottawa were assigned to one of three study groups through quasi-randomisation, taking into account gender, speciality and rater experience. In a counter-balanced design, each group received either positive, negative or no LH prior to watching six simulated learner–patient encounter videos. Participants rated each video using the mini-CEX and completed a questionnaire on the raters’ general impressions of LH. A significant difference in the mean mini-CEX competency scale scores between the negative (M = 5.29) and positive (M = 5.97) LH groups ( P < .001, d = 0.81) was noted. Similar findings were found for the single overall clinical competence ratings. In the post-study questionnaire, 22/28 (78%) of participants had correctly deduced the purpose of the study and 14/28 (50%) felt LH did not influence their assessment. LH influenced mini-CEX scores despite raters’ awareness of the potential for bias. These results suggest that LH could influence a rater’s performance assessment and careful consideration of the potential implications of LH is required.

你有多大偏见？先前表现信息对主治医师评分的影响以及对学习者交接的影响

学习者交接 (LH) 是在教师主管之间共享学习者信息的过程，允许在基于能力的教育模型中进行纵向评估。然而，人们担心对未来评估产生偏见的可能性。本研究的目的是确定先前的表现信息（如 LH）是否会影响临床环境中学习者的评估。在 2017 年 12 月至 2018 年 6 月期间，渥太华大学医学系的 42 名教职员工和最后一年的住院医师通过准随机分配被分配到三个研究组之一，并考虑了性别、专业和评估者的经验。在平衡设计中，每组在观看六个模拟的学习者与患者遭遇视频之前接受阳性、阴性或无 LH。参与者使用 mini-CEX 对每个视频进行评分，并完成了一份关于评分者对 LH 总体印象的问卷。注意到阴性 (M = 5.29) 和阳性 (M = 5.97) LH 组之间的平均 mini-CEX 能力量表得分存在显着差异 ( P < .001, d = 0.81)。对于单一的整体临床能力评级，也发现了类似的发现。在研究后问卷中，22/28 (78%) 的参与者正确推断了研究的目的，14/28 (50%) 认为 LH 不会影响他们的评估。尽管评估者意识到存在偏见的可能性，但 LH 影响了 mini-CEX 分数。这些结果表明 LH 可能会影响评分者的绩效评估，需要仔细考虑 LH 的潜在影响。
