    The business of educating the next generation of surgeons
    (Elsevier, 2018) Sudan, Ranjan; Olivere, Lindsey A.; Nussbaum, Michael S.; Dunnington, Gary L.; Surgery, School of Medicine
    Surgical education community needs to be informed about how education is funded and how it is threatened. In order to explore these issues the Association of Surgical Education convened a panel with significant experience in managing surgery departments to discuss the business of surgical education. They specifically addressed methods to recognize and reward faculty, educate residents on safety, quality and cost, and increase departmental revenue. This information is important in the current educational environment where there is an increased need for institutions to find alternate revenue streams to sustain graduate medical education. It is also important to find additional revenue streams to fund new residency slots to accommodate the greater number medical students who have been admitted to medical schools in response to meet the projected shortage of physicians.

    Development of ASMBS Research Agenda for Bariatric Surgery Using the Delphi Methodology
    (Elsevier, 2019) Stefanidis, Dimitrios; King, Wendy C.; Puzziferri, Nancy; Butler, Annabelle R.; Hutter, Matthew; Sudan, Ranjan; Surgery, School of Medicine
    Background While the number of research publications related to bariatric surgery have increased remarkably in the past decade, research efforts remain uncoordinated and have limited focus, and numerous important questions remain unanswered. Objective To generate a research agenda in bariatric surgery. Setting National survey. Methods The membership of the American Society of Metabolic and Bariatric Surgery (ASMBS) was asked to submit research questions needed to advance the field of bariatric surgery. An expert panel grouped and collated submitted questions and redistributed them back to the membership to rate their importance on a 5-point Likert scale using a 3-round modified Delphi methodology. The top research questions were determined based on provided rankings. Results Two hundred ninety-two research questions were initially submitted that were collapsed to 59 unique questions. The ratings for the top 40 questions ranged from 2.67–4.33 (overall mean, 3.46). The highest-ranked questions centered on the mechanisms of effectiveness of bariatric surgery for weight loss and diabetes resolution, the underlying etiology of weight recidivism, and predictors of success. Conclusions A research agenda for bariatric surgery was developed using the Delphi methodology. This research agenda may enhance the ability of investigators and funding organizations, including the ASMBS, to focus attention to areas most likely to advance the field, and by editors and reviewers to assess the merit and relevance of scientific contributions.

    Proving the Effectiveness of the Fundamentals of Robotic Surgery (FRS) Skills Curriculum: A Single-blinded, Multispecialty, Multi-institutional Randomized Control Trial
    (Lippincott, 2020-08) Satava, Richard M.; Stefanidis, Dimitrios; Levy, Jeffrey S.; Smith, Roger; Martin, John R.; Monfared, Sara; Timsina, Lava R.; Wardkes Darzi, Ara; Moglia, Andrea; Brand, Timothy C.; Dorin, Ryan P.; Dumon, Kristoffel R.; Francone, Todd D.; Georgiou, Evangelos; Goh, Alvin C.; Marcet, Jorge E.; Martino, Martin A.; Sudan, Ranjan; Vale, Justin; Gallagher, Anthony G.; Surgery, School of Medicine
    Objective: To demonstrate the noninferiority of the fundamentals of robotic surgery (FRS) skills curriculum over current training paradigms and identify an ideal training platform. Summary Background Data: There is currently no validated, uniformly accepted curriculum for training in robotic surgery skills. Methods: Single-blinded parallel-group randomized trial at 12 international American College of Surgeons (ACS) Accredited Education Institutes (AEI). Thirty-three robotic surgery experts and 123 inexperienced surgical trainees were enrolled between April 2015 and November 2016. Benchmarks (proficiency levels) on the 7 FRS Dome tasks were established based on expert performance. Participants were then randomly assigned to 4 training groups: Dome (n = 29), dV-Trainer (n = 30), and DVSS (n = 32) that trained to benchmarks and control (n = 32) that trained using locally available robotic skills curricula. The primary outcome was participant performance after training based on task errors and duration on 5 basic robotic tasks (knot tying, continuous suturing, cutting, dissection, and vessel coagulation) using an avian tissue model (transfer-test). Secondary outcomes included cognitive test scores, GEARS ratings, and robot familiarity checklist scores. Results: All groups demonstrated significant performance improvement after skills training (P < 0.01). Participating residents and fellows performed tasks faster (DOME and DVSS groups) and with fewer errors than controls (DOME group; P < 0.01). Inter-rater reliability was high for the checklist scores (0.82–0.97) but moderate for GEARS ratings (0.40–0.67). Conclusions: We provide evidence of effectiveness for the FRS curriculum by demonstrating better performance of those trained following FRS compared with controls on a transfer test. We therefore argue for its implementation across training programs before surgeons apply these skills clinically.
