Background
Informed consent is of paramount importance in surgery. Digital media can be used to enhance patient’s comprehension of the proposed operation. The objective of this study was to examine ...the effects of adding a digital educational platform (DEP) to a standard verbal consent (SVC) for a laparoscopic Roux-en-Y gastric bypass (LRYGB) on patient’s knowledge of the procedure, satisfaction with the clinical encounter and duration of the consent appointment.
Methods
This prospective non-blinded randomized controlled trial allocated 51 patients, who were candidates for a LRYGB, into DEP+SVC (intervention,
n
= 26) or SVC (control,
n
= 25) groups. Data were collected at one Bariatric Centre of Excellence (Ontario, Canada) between December 2018 and December 2019. DEP consisted of a 29-slide video-supplemented module detailing the risks, benefits, expectations and outcomes for the LRYGB. Primary outcome was knowledge about the LRYGB operation following the consent discussion. Secondary outcomes were knowledge retention, patient satisfaction, and duration of time required to obtain an informed consent.
Results
Baseline demographic data were equivalent between groups except for a greater proportion of male patients in the DEP+SVC group (7/19 vs 0/25;
p
< 0.01). Baseline procedure-specific knowledge was equivalent between the groups (72.3 ± 11.3% vs 74.7 ± 9.6%;
p
= 0.41). Post-consent knowledge was significantly higher in the DEP + SVC vs SVC group (85.0 ± 8.8% vs 78.7 ± 8.7%;
p
= 0.01; ES = 0.72). The duration of time to obtain informed consent was significantly shorter for the DEP + SVC vs SVC group (358 ± 198 sec vs 751 ± 212 sec;
p
< 0.01; ES = 1.92). There was no difference in knowledge retention at 4–6 weeks (84.4 ± 10.2% vs 82.9 ± 6.8%;
p
= 0.55) and in patient satisfaction (31.5 ± 1.1 vs 31 ± 2.7;
p
= 0.10).
Conclusion
The addition of a DEP online module to a standard verbal consent for LRYGB resulted in improved patient’s understanding of the procedure-specific risks and benefits, high patient satisfaction, and over 50% time savings for the bariatric surgeon conducting the consent discussion.

Background
Suturing is a fundamental skill in undergraduate medical education. It can be taught by faculty-led, peer tutor-led, and holography-augmented methods; however, the most educationally ...effective and cost-efficient method for proficiency-based teaching of suturing is yet to be determined.
Methods
We conducted a randomized controlled trial comparing faculty-led, peer tutor-led, and holography-augmented proficiency-based suturing training in pre-clerkship medical students. Holography-augmented training provided holographic, voice-controlled instructional material. Technical skill was assessed using hand motion analysis every ten sutures and used to construct learning curves. Proficiency was defined by one standard deviation within average faculty surgeon performance. Intervention arms were compared using one-way ANOVA of the number of sutures placed, full-length sutures used, time to proficiency, and incremental costs incurred. Surveys were used to evaluate participant preferences.
Results
Forty-four students were randomized to the faculty-led (
n
= 16), peer tutor-led (
n
= 14), and holography-augmented (
n
= 14) intervention arms. At proficiency, there were no differences between groups in the number of sutures placed, full-length sutures used, and time to achieve proficiency. The incremental costs of the holography-augmented method were greater than faculty-led and peer tutor-led instruction ($247.00 ± $12.05,
p
< 0.001) due to the high cost of the equipment. Faculty-led teaching was the most preferred method (78.0%), while holography-augmented was the least preferred (0%). 90.6% of students reported high confidence in performing simple interrupted sutures, which did not differ between intervention arms (faculty-led 100.0%, peer tutor-led 90.0%, holography-augmented 83.3%,
p
= 0.409). 93.8% of students felt the program should be offered in the future.
Conclusion
Faculty-led and peer tutor-led instructional methods of proficiency-based suturing teaching were superior to holography-augmented method with respect to costs and participants’ preferences despite being educationally equivalent.

Background A growing body of evidence suggests that nontechnical skills (NTS) of surgeons play an important role in patient safety in the operating room and can be improved through specific training ...interventions. The need to address communication and interpersonal skills in postgraduate medical education has been emphasized by the respective regulatory bodies for accreditation and certification. The present review had 2 purposes: To provide an overview of current approaches to training and assessment of NTS in surgery and to critically appraise the strength of the evidence supporting their effectiveness. Methods A systematic search of the literature (Ovid MEDLINE; PsycINFO; Embase) was conducted using predefined inclusion criteria. The evidence for the main outcome themes was appraised using the GRADE approach. Results Of the 2,831 identified records, 23 were selected for qualitative synthesis. Four randomized, controlled trials and 19 observational pre–post studies were reviewed. Significant effects of training were shown for the identified outcome themes (patient-centered communication, teamwork, decision making, coping with stress, patient safety and error management). The overall strength of evidence supporting training effects on outcome measures was graded as “moderate” (teamwork), “low” (patient-centered communication, decision making, and coping with stress), and “very low” (patient safety and error management), respectively. Conclusion Training interventions can have positive effects on residents' nontechnical knowledge, skills, and attitudes. Although the overall strength of evidence is moderate at best, recent interventions provide valuable information regarding instructional strategies and methods for training and assessment of NTS in modern surgical curricula.

Background There is no objective scale for assessment of operative skill in laparoscopic gastric bypass (LGBP). The objective of this study was to develop and demonstrate feasibility of use, ...validity, and reliability of a Bariatric Objective Structured Assessment of Technical Skill (BOSATS) scale. Study Design The BOSATS scale was developed using a hierarchical task analysis (HTA), a Delphi questionnaire, and a panel of international experts in bariatric surgery. The feasibility of use, reliability, and validity of the developed scale were demonstrated by reviewing 52 prospectively collected video recordings of LGBP performed by novice and experienced surgeons. Results A total of 214 discrete steps were identified in HTA. A total of 12 and 17 panel members completed the first and second round of the Delphi questionnaire, respectively. Consensus among the panel was achieved after the second round (Cronbach's alpha = 0.85). The BOSATS scale demonstrated high inter-rater (intraclass correlation coefficient ICC = 0.954; p < 0.001) and test-retest reliability (ICC = 0.99; p < 0.001). Significant differences between BOSATS scores of experienced and novice surgeon groups were noted for the creation of jejunojejunostomy (JJ), gastric pouch, linear stapled gastrojejunostomy (GJ), circular stapled GJ, and hand-sewn GJ. Moderate to high correlations between BOSATS scale and Objective Structured Assessment of Technical Skills Global Rating Scale (OSATS GRS) were seen for JJ (rho = 0.59; p = 0.001), gastric pouch (rho = 0.48; p = 0.0004), linear stapled GJ (rho = 0.70; p = 0.0001), and hand-sewn GJ (rho = 0.96; p < 0.0001). Conclusions The BOSATS scale is a feasible to use, reliable, and valid instrument for objective assessment of operative performance in LGBP. Implementation of this scale is expected to facilitate deliberate practice and provide a means for future certification in bariatric surgery.
Abstract
Background
With over 26% of Canadian adults living with obesity, undergraduate medical education (UGME) should prepare medical students to manage this chronic disease. It is currently ...unknown how the management of patients living with obesity is taught within UGME curricula in Canada. This study (1) examined the knowledge and self-reported competence of final-year medical students in managing patients living with obesity, and (2) explored how this topic is taught within UGME curricula in Canada.
Methods
We distributed two online surveys: one to final-year medical students, and another to UGME deans at 9 English-speaking medical schools in Canada. The medical student survey assessed students’ knowledge and self-reported competence in managing patients living with obesity. The dean’s survey assessed how management of patients living with obesity is taught within the UGME curriculum.
Results
One hundred thirty-three (6.9%) and 180 (9.3%) out of 1936 eligible students completed the knowledge and self-reported competence parts of the survey, respectively. Mean knowledge score was 10.5 (2.1) out of 18. Students had greatest knowledge about etiology of obesity and goals of treatment, and poorest knowledge about physiology and maintenance of weight loss. Mean self-reported competence score was 2.5 (0.86) out of 4. Students felt most competent assessing diet for unhealthy behaviors and calculating body mass index. Five (56%) out of 9 deans completed the survey. A mean of 14.6 (5.0) curricular hours were spent on teaching management of patients living with obesity. Nutrition and bariatric surgery were most frequently covered topics, with education delivered most often via large-group sessions and clinical activities.
Conclusions
Canadian medical students lack adequate knowledge and feel inadequately prepared to manage patients living with obesity. Changes to UGME curricula may help address this gap in education.
Introduction Simulation training for surgical residents can shorten learning curves, improve technical skills, and expedite competency. Several studies have shown that skills learned in the simulated ...environment are transferable to the operating room. Residency programs are trying to incorporate simulation into the resident training curriculum to supplement the hands-on experience gained in the operating room. Despite the availability and proven utility of surgical simulators and simulation laboratories, they are still widely underutilized by surgical trainees. Studies have shown that voluntary use leads to minimal participation in a training curriculum. Although there are several simulation tools, there is no clear evidence of the superiority of one tool over the other in skill acquisition. The purpose of this study was to explore resident perceptions, training experiences, and preferences regarding laparoscopic simulation training. Our goal was to profile resident participation in surgical skills simulation, recognize potential barriers to voluntary simulator use, and identify simulation tools and tasks preferred by residents. Furthermore, this study may help to inform whether mandatory/protected training time, as part of the residents’ curriculum is essential to enhance participation in the simulation laboratory. Methods A cross-sectional study on general surgery residents (postgraduate years 1-5) at Yale University School of Medicine and the University of Toronto via an online questionnaire was conducted. Overall, 67 residents completed the survey. The institutional review board approved the methods of the study. Results Overall, 95.5% of the participants believed that simulation training improved their laparoscopic skills. Most respondents (92.5%) perceived that skills learned during simulation training were transferrable to the operating room. Overall, 56.7% of participants agreed that proficiency in a simulation curriculum should be mandatory before operating room experience. The simulation laboratory was most commonly used during work hours; lack of free time during work hours was most commonly cited as a reason for underutilization. Factors influencing use of the simulation laboratory in order of importance were the need for skill development, an interest in minimally invasive surgery, mandatory/protected time in a simulation environment as part of the residency program curriculum, a recommendation by an attending surgeon, and proximity of the simulation center. The most preferred simulation tool was the live animal model followed by cadaveric tissue. Virtual reality simulators were among the least-preferred (25%) simulation tools. Most residents (91.0%) felt that mandatory/protected time in a simulation environment should be introduced into resident training protocols. Conclusions Mandatory and protected time in a simulation environment as part of the resident training curriculum may improve participation in simulation training. A comprehensive curriculum, which includes the use of live animals, cadaveric tissue, and virtual reality simulators, may enhance the laparoscopic training experience and interest level of surgical trainees.

Educational interventions with proven effectiveness to reduce medication prescribing errors are currently lacking. Our objective was to implement and assess the effectiveness of a curriculum to ...reduce medication prescribing errors on a surgery service.
This was a prospective observational cohort study at a Canadian academic hospital without an electronic order entry system. A pharmacist-led medication prescribing curriculum for surgery residents was developed and implemented over 2 days (2 h/day) in July 2019. Thirteen (76%) out of 17 surgery residents contributed pre-implementation data, while 13 (81%) out of 16 surgery residents contributed post-implementation data. Medication prescribing errors were tracked for 12 months pre-implementation and 6 months post-implementation. Errors were classified as prescription writing (PW) or decision making (DM).
There were a total of 1050 medication prescribing errors made in the pre-implementation period with 615 (59%) PW errors and 435 (41%) DM. There were a mean of 87.5 (SD = 14.6) total medication prescribing errors per month in the pre-implementation period with 51.3 (11.9) PW and 36.3 (6.0) DM errors. There were a total of 472 medication prescribing errors made in the post-implementation period with 260 (55%) PW and 212 (45%) DM errors. There were a mean of 78.7 (10.3) total medication prescribing errors per month in the post-implementation period with 43.3 (9.5) PW and 35.3 (4.2) DM errors. In the first quarter of the academic year, there were significantly fewer mean total errors per month post-implementation versus pre-implementation (77.7(12.7) versus 107.3(8.1);
= .035), with significantly fewer PW errors per month (40.7(13.2) versus 68.7(9.3);
= .046) and no difference in DM errors per month (37.0(2.0) versus 38.7(5.7);
= .671). There were no differences noted in the second quarter of the academic year.
Medication prescribing errors occurred from PW and DM. Medication prescribing curriculum decreased PW errors; however, a continued education program is warranted as the effect diminished over time.
A fundamental aspect of surgical planning in liver resections is the identification of key vessel tributaries to preserve healthy liver tissue while fully resecting the tumor(s). Current surgical ...planning relies primarily on the surgeon’s ability to mentally reconstruct 2D computed tomography/magnetic resonance (CT/MR) images into 3D and plan resection margins. This creates significant cognitive load, especially for trainees, as it relies on image interpretation, anatomical and surgical knowledge, experience, and spatial sense. The purpose of this study is to determine if 3D reconstruction of preoperative CT/MR images will assist resident-level trainees in making appropriate operative plans for liver resection surgery.
Ten preoperative patient CT/MR images were selected. Images were case-matched, 5 to 2D planning and 5 to 3D planning. Images from the 3D group were segmented to create interactive digital models that the resident can manipulate to view the tumor(s) in relation to landmark hepatic structures. Residents were asked to evaluate the images and devise a surgical resection plan for each image. The resident alternated between 2D and 3D planning, in a randomly generated order. The primary outcome was the accuracy of resident’s plan compared to expert opinion. Time to devise each surgical plan was the secondary outcome. Residents completed a prestudy and poststudy questionnaire regarding their experience with liver surgery and the 3D planning software.
Senior level surgical residents from the Queen’s University General Surgery residency program were recruited to participate.
A total of 14 residents participated in the study. The median correct response rate was 2 of 5 (40%; range: 0-4) for the 2D group, and 3 of 5 (60%; range: 1-5) for the 3D group (p < 0.01). The average time to complete each plan was 156 ± 107 seconds for the 2D group, and 84 ± 73 seconds for the 3D group (p < 0.01). A total 13 of 14 residents found the 3D model easier to use than the 2D. Most residents noticed a difference between the 2 modalities and found that the 3D model improved their confidence with the surgical plan proposed.
The results of this study show that 3D reconstruction for liver surgery planning increases accuracy of resident surgical planning and decreases amount of time required. 3D reconstruction would be a useful model for improving trainee understanding of liver anatomy and surgical resection, and would serve as an adjunct to current 2D planning methods. This has the potential to be developed into a module for teaching liver surgery in a competency-based medical curriculum.

All Canadian Residency Matching Service (CaRMS) R1 interviews were conducted virtually for the first time in 2021. We explored the facilitators, barriers, and implications of the virtual interview ...process for the CaRMS R1 match and provide recommendations for improvement.
We conducted a cross-sectional survey study of CaRMS R1 residency applicants and interviewers across Canada in 2021. Surveys were distributed by email to the interviewers, and by email, social media, or newsletter to the applicants. Inductive thematic analysis was used for open-ended items. Recommendations were provided as frequencies to demonstrate strength. Close-ended items were described and compared across groups using Chi-Square Fisher's Exact tests.
A total of 127 applicants and 400 interviewers, including 127 program directors, responded to the survey. 193/380 (50.8%) interviewers and 90/118 (76.3%) applicants preferred virtual over in-person interview formats. Facilitators of the virtual interview format included cost and time savings, ease of scheduling, reduced environmental impact, greater equity, less stress, greater reach and participation, and safety. Barriers of the virtual interview format included reduced informal conversations, limited ability for applicants to explore programs at different locations, limited ability for programs to assess applicants' interest, technological issues, concern for interview integrity, limited non-verbal communication, and reduced networking. The most helpful media for applicants to learn about residency programs were program websites, the CaRMS/AFMC websites, and recruitment videos. Additionally, panel interviews were preferred by applicants for their ability to showcase themselves and build connections with multiple interviewers. Respondents provided recommendations regarding: (1) dissemination of program information, (2) the use of technology, and (3) the virtual interview format.
Perceptions of 2021 CaRMS R1 virtual interviews were favourable among applicants and interviewers. Recommendations from this study can help improve future iterations of virtual interviews.
