There is a growing need for effective surgical simulators to train the novice resident with a core skill set that can be later used in advanced operating room training. The most common simulator-based laparoscopic skills curriculum, the Fundamentals of Laparoscopic Skills (FLS), has been demonstrated to effectively teach basic surgical skills; however, a key deficiency in current surgical simulators is lack of validated training for force-based or haptic skills. In this study, a novel haptic simulator was examined for construct validity by determining its ability to differentiate between the force skills of surgeons and novices. ⋯ The haptic simulator successfully differentiated between novice and surgeon force skill level at specific ranges for all 3 salient haptic tasks, establishing initial construct validity of the haptic simulator. Based on these results, force-based simulator metrics may be used to objectively measure haptic skill level and potentially train residents. Haptic simulator development should focus on the 3 salient haptic skills (grasping, probing, and sweeping) where precise force application is necessary for successful task outcomes.

The purpose of this study was to explore the relationship between qualifying examination (QE) and certifying examination (CE) results and to determine whether an appropriate cut-point on the QE would predict success on the CE. ⋯ While a moderate relationship between QE scores and CE performance is evident, correlations suggest that the 2 examinations measure different abilities. The low AUC value on the ROC analysis, along with poor predictability at all possible cut-points, show that no appropriate cut-point on the QE predicts success on the CE. These data add to the validity of both tests by providing evidence that distinct latent traits are being measured by both tests.

The purpose of this study was to determine the impact of the initiation of a pediatric surgery fellowship on general surgery resident operative volume at 1 major academic institution. ⋯ Even with an increase in the number of attending surgeons, RVUs, and admissions, the fellowship resulted in a decrease in general surgery resident index and overall case volume in pediatric surgery. Although operative volume is only 1 measure of surgical educational value, these findings suggest that the addition of surgical fellowships affects the educational experience of general surgery residents. We recommend that residency programs establish goals and calculate any potential impact on general surgery resident case volume before initiating a new surgical fellowship.

Structured training on box trainers for first year surgical residents: does it improve retention of laparoscopic skills? A randomized controlled study.
Structured training on box trainers in laparoscopic skills in the initial years of residency has been used and found to be effective. Although there are studies that confirm immediate improvement after training, there is a lack of well-designed trials addressing the crucial issue of retention of these skills over time. The purpose of this study is to assess improvement in laparoscopic skills of surgical trainees after structured training on box trainers, compared with traditional training (observing and assisting laparoscopic procedures in the operation rooms) immediately and after 5 months. ⋯ Structured training on box trainers, in addition to traditional training, compared with traditional training alone, leads to better skills and improved confidence of residents. There is significant retention of skills at the end of 5 months. These results provide support for incorporation of structured training with box trainers for laparoscopic skills into surgical training programs.

Randomized Controlled Trial
Residents can successfully teach basic surgical skills in the simulation center.
Basic surgical skills are frequently taught to surgical interns in simulation centers. Faculty recruitment for teaching of these sessions can be difficult. The goal of this study was to determine whether senior surgical residents can effectively teach basic surgical skills to provide an alternative to faculty-led instruction. ⋯ In the simulation center, teaching by senior surgical residents and faculty members resulted in comparable improvement in interns' basic surgical skills. These findings could increase the skill instructor pool for teaching in the simulation center, potentially easing recruitment and providing senior residents with teaching opportunities.
