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.

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.

Randomized Controlled Trial Comparative Study
Comparing video games and laparoscopic simulators in the development of laparoscopic skills in surgical residents.
The video game industry has become increasingly popular over recent years, offering photorealistic simulations of various scenarios while requiring motor, visual, and cognitive coordination. Video game players outperform nonplayers on different visual tasks and are faster and more accurate on laparoscopic simulators. The same qualities found in video game players are highly desired in surgeons. Our investigation aims to evaluate the effect of video game play on the development of fine motor and visual skills. Specifically, we plan to examine if handheld video devices offer the same improvement in laparoscopic skill as traditional simulators, with less cost and more accessibility. ⋯ Studies have shown that residents who engage in video games have better visual, spatial, and motor coordination. We showed that over 6 weeks, residents who played video games improved in their laparoscopic skills more than those who practiced on laparoscopic simulators. The accessibility of gaming systems is 1 of the most essential factors making these tools a good resource for residents. Handheld games are especially easy to use and offer a readily available means to improve visuospatial and motor abilities.

Proficiency of surgical faculty and residents with ethical dilemmas: is modeling enough?
Professionalism, an Accreditation Commission for Graduate Medical Education (ACGME) competency, embraces the concept of adherence to ethical principles. Despite this, most surgical residencies do not currently include ethics as part of their core curriculum. Further, expertise in effectively managing ethical dilemmas is frequently obtained via modeling after the attending physician. This study evaluated surgical faculty (SF) and residents (SR) on their understanding of basic ethical principles and their overall confidence in translation of these principles into clinical practice. The objective was to determine if there are any differences in the overall levels of knowledge and confidence in ethics between SR and SF. ⋯ While SF are more confident in their ethical decision-making, their fundamental knowledge base in ethics is not different from that of SR. Female SF report greater self-confidence over their male counterparts. In total, SF may not possess the foundation to effectively mentor residents in appropriate ethical principles and their translation to clinical practice. This study supports the need for both SR and SF to engage in an integrated education program in ethics to promote on-going dialogue in this complex topic.

Previously, we identified a positive correlation between administration of regularly structured mock oral examinations and successful first time pass rates on the American Board of Surgery Certifying Examination (ABSCE)/oral boards. In this study, we investigated factors associated with test results to determine whether residents at risk of not passing the ABSCE can be identified a priori. ⋯ Compared with a control group of residents from the same program, residents who passed the ABSCE examination on the first attempt were more likely to have higher USMLE Step 2 and professional communication scores. USMLE Step 1 scores and English as a native language were not associated with certifying examination pass rates. These criteria may offer guidance for residents preparing to take the ABSCE and may aid in the selection of residents for residency programs. Larger studies to validate these findings and to investigate the role of improving communication skills and conducting interventions between the 1st and 2nd attempt are warranted.
