Wound closure in open surgery is a fundamental skill acquired early during the surgeon's career. Individual modifications are adopted frequently by the more experienced surgeon in an effort to increase efficiency. To date, there has been no objective measurement regarding whether these modifications significantly impact economy of movement or procedure time. The advent of the Imperial College Surgical Assessment Device (ICSAD) allows standardized, objective evaluation of a novel suture technique for wound closure (study group) developed by one of the senior authors (DBH) and compares the technique to the current method taught by the Royal College of Surgeons of Great Britain and Ireland (control group). Ten surgical registrars underwent both tasks in a standardized manner for five repetitions. Mean total movements and duration of procedure were decreased significantly for the study group (analysis of variance: = 0.018 and = 0.033 respectively) with an economy index (total movements/total time) of 0.79 movements per second for the control group vs. 0.67 for the study group. This study demonstrates ICSAD's usefulness in defining a novel suture technique as a more efficient method of cutaneous closure than the currently advocated technique.
