Structured assessment of microsurgery skills in the clinical setting.

Abstract

Microsurgery is an essential component in plastic surgery training. Competence has become an important issue in current surgical practice and training. The complexity of microsurgery requires detailed assessment and feedback on skills components. This article proposes a method of Structured Assessment of Microsurgery Skills (SAMS) in a clinical setting. Three types of assessment (i.e., modified Global Rating Score, errors list and summative rating) were incorporated to develop the SAMS method. Clinical anastomoses were recorded on videos using a digital microscope system and were rated by three consultants independently and in a blinded fashion. Fifteen clinical cases of microvascular anastomoses performed by trainees and a consultant microsurgeon were assessed using SAMS. The consultant had consistently the highest scores. Construct validity was also demonstrated by improvement of SAMS scores of microsurgery trainees. The overall inter-rater reliability was strong (alpha=0.78). The SAMS method provides both formative and summative assessment of microsurgery skills. It is demonstrated to be a valid, reliable and feasible assessment tool of operating room performance to provide systematic and comprehensive feedback as part of the learning cycle.
