From the clinical point of view, it is important to recognize residents' level expertise with regard basic psychomotor skills. For that reason, surgeons and surgical organizations (e.g., Acreditation Council for Graduate Medical Education, ACGME) are calling assessment tools credential residents as technically competent. Currently, no method universally accepted or recommended classifying "experienced," "intermediates," "novices" according their technical abilities. This study introduces a classification recognizing experience in laparoscopic surgery based on skills alone.For this study, 10 experienced (>100 procedures performed), intermediates (10-100 11 novices (no experience) performed four tasks box trainer. The movements instruments were recorded TrEndo tracking system analyzed using six motion analysis parameters (MAPs). MAPs all participants submitted principal component (PCA), data reduction technique. scores first components used perform linear discriminant (LDA), method. Performance LDA was examined leave-one-out cross-validation.Of 31 participants, 23 classified correctly proposed method, 7 categorized experienced, intermediates, 9 novices.The provides means classify objectively intermediate, novice Due simplicity generalizability introduced easy implement existing trainers.
