Popis: Introduction: The mini-Clinical Evaluation Exercise (CEX) is meant to provide on the spot feedback to trainees. We hypothesised that an ultra-short assessment tool with just one global entrustment scale (micro-CEX) would encourage faculty to provide better feedback compared to the traditional multiple domain mini-CEX. Methods: 59 pairs of faculty and trainees from internal medicine completed both the 7-item mini-CEX and a micro-CEX and were surveyed regarding their perceptions of the 2 forms. Wordcount and specificity of the feedback was assessed. Participants were subsequently interviewed to elicit their views on factors affecting the utility of the CEX. Results: Quantity and quality of feedback increased with the micro-CEX compared to the mini-CEX. Wordcount increased from 9.5 to 17.5 words, and specificity increased from 1.6 to 2.3 on a 4-point scale, p < 0.05 in both cases. Faculty and residents both felt the micro-CEX provided better assessment and feedback. The micro-CEX, but not the mini-CEX, was able to discriminate between residents in different years of training. The mini-CEX showed a strong halo effect between different domains of scoring. In interviews, ease of administration, immediacy of assessment, clarity of purpose, structuring of desired feedback, assessor-trainee pairing and alignment with trainee learning goals were identified as important features to optimize utility of the (mini or micro or both) CEX. Conclusions: Simplifying the assessment component of the CEX frees faculty to concentrate on feedback and this improves both quantity and quality of feedback. How the form is administered on the ground impacts its practical utility.
