Evaluating the Quality of Narrative Feedback for Entrustable Professional Activities in a Surgery Residency Program.

OBJECTIVE: We assessed the quality of narrative feedback given to surgical residents during the first five years of Competency-Based Medical Education (CBME) implementation. SUMMARY BACKGROUND DATA: CBME requires ongoing formative assessments and feedback on learners' performance. METHODS: We conducted a retrospective cross-sectional study using assessments of Entrustable Professional Activities (EPAs) in the Surgical Foundations curriculum at Queen's University from 2017-2022. Two raters independently evaluated quality of narrative feedback using the Quality of Assessment of Learning (QuAL) Score (0-5). RESULTS: A total of 3,900 EPA assessments were completed over 5 years. Fifty-seven percent (2229/3900) of assessments had narrative feedback documented with a mean QuAL score of 2.16±1.49. Of these, 1614 (72.4%) provided evidence about the resident's performance, 951 (42.7%) provided suggestions for improvement, and 499/2229 (22.4%) connected suggestions to the evidence. There was no meaningful change in narrative feedback quality over time (r=0.067, P=0.002). Variables associated with lower quality of narrative feedback include: Attending role (2.04±1.48) compared to medical student (3.13±1.12, P<0.001) and clinical fellow (2.47±1.54, P<0.001), concordant specialties between the assessor and learner (2.06±1.50 vs. 2.21±1.49, P=0.025), completion of the assessment one month or more after the encounter versus one week (1.85±1.48 vs. 2.23±1.49, P<0.001), and resident entrustment versus not entrusted to perform the assessed EPA (2.13±1.45 vs. 2.35±1.66; P=0.008). The quality of narrative feedback was similar for assessments completed under direct and indirect observation (2.18±1.47 vs. 2.06±1.54; P=0.153). CONCLUSIONS: Just over half of the EPA assessments of surgery residents contained narrative feedback with overall fair quality. There was no meaningful change in the quality of feedback over 5 years. These findings prompt future research and faculty development.

Assessment of guidelines for bariatric and metabolic surgery: a systematic review and evaluation using appraisal of guidelines for research and evaluation II (AGREE II).

BACKGROUND: In recent years, multiple guidelines on bariatric and metabolic surgery were published, however, their quality remains unknown, leaving providers with uncertainty when using them to make perioperative decisions. This study aims to evaluate the quality of existing guidelines for perioperative bariatric surgery care. METHODS: A comprehensive search of MEDLINE and EMBASE were conducted from January 2010 to October 2022 for bariatric clinical practice guidelines. Guideline evaluation was carried out using the Appraisal of Guidelines for Research and Evaluation II (AGREE II) framework. RESULTS: The initial search yielded 1483 citations, of which, 26 were included in final analysis. The overall median domain scores for guidelines were: (1) scope and purpose: 87.5% (IQR: 57-94%), (2) stakeholder involvement: 49% (IQR: 40-64%), (3) rigor of development: 42.5% (IQR: 22-68%), (4) clarity of presentation: 85% (IQR: 81-90%), (5) applicability: 6% (IQR: 3-16%), (6) editorial independence: 50% (IQR: 48-67%), (7) overall impressions: 48% (IQR: 33-67%). Only six guidelines achieved an overall score >70%. CONCLUSIONS: Bariatric surgery guidelines effectively outlined their aim and presented recommendations. However, many did not adequately seek patient input, state search criteria, use evidence rating tools, and consider resource implications. Future guidelines should reference the AGREE II framework in study design.

Optimizing the consent process for emergent laparoscopic cholecystectomy using an interactive digital education platform: a randomized control trial.

BACKGROUND: Informed consent is essential for any surgery. The use of digital education platforms (DEPs) can enhance patient understanding of the consent discussion and is a method to standardize the consent process in elective, ambulatory settings. The use of DEP as an adjunct to standard verbal consent (SVC) has not been studied in an acute care setting. METHODS: We conducted a prospective randomized control trial with patients presenting to the emergency department of a tertiary care hospital with acute biliary pathology requiring a laparoscopic cholecystectomy (LC) between August 2021 and April 2023. Participants were randomized 1:1 to receive either a DEP module with SVC or SVC alone. Baseline procedure-specific knowledge and self-reported understanding of risks and benefits of LC were collected using a questionnaire. Primary outcome was immediate post-intervention knowledge assessed using a 21-question multiple choice questionnaire. Secondary outcomes were delayed procedure-specific knowledge and participants' satisfaction with the consent discussion. RESULTS: We recruited 79 participants and randomized them 1:1 into the intervention group (DEP + SVC, n = 40) and the control group (SVC, n = 39). Baseline demographics and baseline procedure-specific knowledge were similar between groups. The immediate post-intervention knowledge was significantly higher for participants in the intervention versus the control group with a Cohen's d effect size of 0.68 (85.2(10.6)% vs. 78.2(9.9)%; p = 0.004). Similarly, self-reported understanding of risks and benefits of LC was significantly greater for participants in the intervention versus the control group with a Cohen's effect size of 0.76 (68.5(16.4)% vs. 55.1(18.8)%; p = 0.001). For participants who completed the delayed post-intervention assessment (n = 29), there continued to be significantly higher retention of acquired knowledge in the intervention group with a Cohen's effect size of 0.61 (86.5(8.5)% vs. 79.8 (13.1)%; p = 0.024). There was no difference in participants' self-reported satisfaction with the consent discussion between groups (69.5(6.7)% vs. 67.2(7.7)%; p = 0.149). CONCLUSION: The addition of digital education platform to standard verbal consent significantly improves patient's early and delayed understanding of risks and benefits of LC in an acute care setting.

What are essential laparoscopic skills these days? Results of the SAGES Fundamentals of Laparoscopic Surgery (FLS) Committee technical skills survey.

INTRODUCTION: The Fundamentals of Laparoscopic Surgery (FLS) program tests basic knowledge and skills required to perform laparoscopic surgery. Educational experiences in laparoscopic training and development of associated competencies have evolved since FLS inception, making it important to review the definition of fundamental laparoscopic skills. The Society of American Gastrointestinal and Endoscopic Surgeons (SAGES) assigned an FLS Technical Skills Working Group to characterize technical skills used in basic laparoscopic surgery in current practice contexts and their possible application to future FLS tests. METHODS: A group of subject matter experts defined an inventory of 65 laparoscopic skills using a Nominal Group Technique. From these, a survey was developed rating these items for importance, frequency of use, and priority for testing for FLS certification. This survey was distributed to SAGES members, recent recipients of FLS certification, and members of the Association of Program Directors in Surgery (APDS). Results were collected using a secure web-based survey platform. RESULTS: Complete data were available for 1742 surveys. Of these, 1143 comprised results for post-residency participants who performed advanced procedures. Seventeen competencies were identified for FLS testing prioritization by determining the proportion of respondents who identified them of highest priority, at median (50th percentile) of the maximum survey scale rating. These included basic peritoneal access, laparoscope and instrument use, tissue manipulation, and specific problem management skills. Sixteen could be used to show appropriateness of the domain construct by confirmatory factor analysis. Of these 8 could be characterized as manipulative tasks. Of these 5 mapped to current FLS tasks. CONCLUSIONS: This survey-identified competencies, some of which are currently assessed in FLS, with a high level of priority for testing. Further work is needed to determine if this should prompt consideration of changes or additions to the FLS technical skills test component.

A Canadian survey of residency applicants' and interviewers' perceptions of the 2021 CaRMS R1 virtual interviews.

BACKGROUND: 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. METHODS: 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. RESULTS: 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. CONCLUSIONS: 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.

Digital approach to informed consent in bariatric surgery: a randomized controlled trial.

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.

Consensus priority research questions in gastrointestinal and endoscopic surgery in the year 2020: results of a SAGES Delphi study.

INTRODUCTION: The objectives of this study were to identify consensus priority research questions according to members of the Society of American Gastrointestinal and Endoscopic Surgeons (SAGES), and to explore differences in priorities according to specific membership subgroups. METHODS: A modified Delphi study was conducted including active members of SAGES. An initial list of research questions was compiled by members of 26 SAGES Committees and Task Forces, and was further refined by the SAGES Delphi Task Force. The questions were divided into five research categories: (1) Surgical Outcomes; (2) Education, Training, and Simulation; (3) Health Services Research; (4) New Technology; and (5) Artificial Intelligence. Delphi respondents were asked to rank each question with regards to its importance in the field of gastrointestinal and endoscopic surgery (1-low; 5-high). "Priority" was defined as a single-round mean score of ≥ 3.5, and "consensus" as a single-round standard deviation < 1.0. Subgroup analyses were performed according to a priori selected respondent characteristics. RESULTS: The total number of respondents for each round was: Round 1 (n = 407); Round 2 (n = 569); Round 3 (n = 273). In each round, the majority of respondents were male (Round 1: 77.4%; Round 2: 77.1%; Round 3: 76.7%), self-identified as academic (vs. community) surgeons (Round 1: 57.1%; Round 2: 61.1%; Round 3: 60.2%), and practiced in North America (Round 1: 71.8%; Round 2: 70.8%; Round 3: 75.9%). A total of 29 out of 122 research questions met criteria for both "priority" and "consensus"-Surgical Outcomes, n = 6; Education, Training, and Simulation, n = 9; Health Services Research, n = 5; New Technology, n = 5; and Artificial Intelligence, n = 4. CONCLUSIONS: Consensus priority research questions in gastrointestinal and endoscopic surgery were identified across five different research categories. These results can provide direction and areas of interest for funding and investigation for future studies.

A Canadian survey of medical students and undergraduate deans on the management of patients living with obesity.

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.

Safety and outcomes of performing laparoscopic Roux-en-Y gastric bypass and sleeve gastrectomy at an ambulatory site of a tertiary care hospital in Ontario.

BACKGROUND: In Ontario, bariatric surgery is publicly funded and is performed only in accredited tertiary care hospitals. The purpose of our study was to report on the safety and outcomes of performing bariatric surgery at an ambulatory site of a tertiary care hospital in southern Ontario. METHODS: We conducted a retrospective cohort study of all adult (age ≥ 18 yr) patients who underwent primary laparoscopic Roux-en-Y gastric bypass (LRYGB) or laparoscopic sleeve gastrectomy (LSG) at the ambulatory site of our tertiary care hospital between September 2016 and August 2018. The 2 sites are 1.4 km apart. Patient demographic characteristics, duration of surgery, intraoperative and 90-day postoperative complications, number of transfers and readmission to the tertiary care hospital, and emergency department visits were collected. RESULTS: A total of 314 patients (285 women [90.8%] and 29 men [9.2%] with a mean age of 41.8 yr [standard deviation (SD) 8.9 yr]) underwent surgery: LRYGB in 295 cases (93.9%) and LSG in 19 (6.0%). The mean body mass index was 45.3 (SD 5.1), the median American Society of Anesthesiologists score was 3 (range 2-4), and the median Edmonton Obesity Staging System score was 2 (range 0-4). The mean operative time was 119.8 (SD 23.1) minutes for LRYGB and 96.2 (SD 22.0) minutes for LSG, and the mean length of stay was 2.1 (SD 0.6) days and 2.1 (SD 0.2) days, respectively. Thirteen patients (4.1%) required transfer to the tertiary care hospital for a postoperative complication. Of 312 patients, 29 (9.3%) presented to emergency department within 90 days after surgery, and 8 (2.6%) required readmission to hospital; no deaths were reported. CONCLUSION: The findings suggest that LRYGB and LSG can be performed safely at an ambulatory site of a tertiary care hospital. However, caution should be exercised in performing these procedures at an ambulatory site without a tertiary care hospital affiliation, as patients may require urgent transfer for a serious postoperative complication.

Factors influencing primary care provider referral for bariatric surgery: Systematic review.

OBJECTIVE: To identify barriers to and facilitators of primary care provider (PCP) referral for bariatric surgery in patients with obesity. DATA SOURCES: MEDLINE, EMBASE, and PsycINFO databases were searched and reference lists of included articles were screened to identify additional relevant articles. Two reviewers independently reviewed citations and full-text articles, and appraised the quality of the included articles using the Critical Appraisal Skills Programme Tool Qualitative Checklist and the Appraisal Tool for Cross-Sectional Studies. They extracted data on the study characteristics and the barriers to and facilitators of PCP referral for bariatric surgery. Appraisal discrepancies were resolved through consensus among authors. STUDY SELECTION: Overall, 882 citations were identified and 18 articles were then selected for this review. SYNTHESIS: Barriers included fear of surgery complications and side effects, cost, lack of availability, perception that surgery is a quick fix or a last resort, and prior negative experiences. Facilitators included direct requests from patients, patient motivation, previously failed weight-loss interventions, and obesity-related comorbidities. Those PCPs who were knowledgeable about the risks and benefits of bariatric surgery were more likely to refer their patients. CONCLUSION: Education and continuing professional development programs regarding bariatric surgery are needed to improve PCP knowledge and capacity to manage patients with obesity. Also, educating the general public on obesity, weight management, and available treatment options can empower patients and families to manage their weight and pursue evidence-informed treatments.

Medication Errors in Surgery: A Classification Taxonomy and a Pilot Study in Postcall Residents.

INTRODUCTION: The post-call state in postgraduate medical trainees is associated with impaired decision-making and increased medical errors. An association between post-call state and medication prescription errors for surgery residents is yet to be established. Our objective was to determine whether post-call state is associated with increased proportion of medication prescription errors committed by surgery residents in an academic hospital without a computerized physician order entry (CPOE) system. METHODS: This prospective observational study was conducted at a tertiary academic hospital between June 28 and August 31, 2017. It compared the proportion of medication prescription errors committed by surgery residents in their post-call (PC) and no-call (NC) states. A novel taxonomy was developed to classify medication prescription errors. RESULTS: Sixteen of twenty-one eligible residents (76%) participated in this study. Self-reported hours of sleep per night was significantly higher in the NC group compared to the PC group (6(4-8) vs 2(0-4) hours, P < 0.01). PC residents committed a significantly higher proportion of medication prescription errors versus NC residents (9.2% vs 3.2%; p=0.04). Decision-making and prescription-writing errors comprised 33% and 67% of errors, respectively. CONCLUSIONS: The post-call state in surgery residents is associated with a significantly higher proportion of medication prescription errors in a hospital without a CPOE system. Decision-making and prescription-writing errors could potentially be addressed by additional educational interventions.

The Next Surgical Skills and Technology Elective Program: The "Surgical Skills and Technology Elective Program" Decreases Cognitive Load During Suturing Tasks in Second Year Medical Students.

OBJECTIVE: The Surgical Skills and Technology Elective Program (SSTEP) is a one-week, simulation-based procedural skills bootcamp for preclinical medical students. Using cognitive load (CL) as a useful framework for understanding simulation in medical education, our aims were to (1) examine the ability of SSTEP to decrease medical students' CL during procedural skills training and (2) determine the impact of SSTEP on secondary learning. METHODS: In this prospective cohort study, twenty SSTEP participants and twenty controls were recruited. CL was assessed during a simple suturing task and a clinical vignette multitasking activity, where participants were required to suture and concurrently listen to a clinical vignette. CL was measured using the validated Subjective Rating of Mental Effort (SRME) and its impact on working memory was assessed using a knowledge test about the clinical vignette. RESULTS: Participants reported lower SRME scores while suturing following SSTEP, which persisted at 3 months (p = 0.002) and were significantly lower than controls (p = 0.031). Participants also reported lower SRME scores during the clinical vignette multitasking activity (p = 0.011), despite no improvement among controls (p = 0.63). Participants significantly outperformed controls on the clinical vignette knowledge test (p = 0.02). CONCLUSIONS: Surgical skills training through SSTEP was associated with lower reports of mental effort and increased performance on secondary learning tasks. Procedural skills bootcamps may better prepare students for the complex learning environments encountered during clinical clerkship.

Survey of perceptions and educational needs of primary care providers regarding management of patients with class II and III obesity in Ontario, Canada.

BACKGROUND: Primary care providers (PCPs) are typically the primary contact for patients with obesity seeking medical and surgical weight loss interventions; however, previous studies suggest that fewer than 7% of eligible adult patients are referred to publically funded medical and surgical weight loss interventions (MSWLI). METHODS: We performed an anonymous survey study between October 2017 and June 2018 to explore the knowledge, experiences, perceptions, and educational needs of PCPs in Southeastern Ontario in managing patients with class II and III obesity. RESULTS: Surveys were distributed to 591 PCPs (n = 538 family physicians; n = 53 nurse practitioners) identified as practicing in the Southeastern Ontario and 92 (15.6%) participated. PCPs serving a rural population estimated that 14.2 ± 10.9% of patients would qualify for MSWLI compared to 9.9 ± 8.5% of patients of PCPs serving an urban population (p = .049). Overall, 57.5% of respondents did not feel competent prescribing MSWLI to patients with class II/III obesity, while 69.8% stated they had 'good' knowledge of the referral criteria for MSWLI. 22.2% of respondents were hesitant to refer patients for bariatric surgery (BS) due to concerns about postoperative surgical complications and risks associated with surgery. Only 25% of respondents were comfortable providing long-term follow up after BS, and only 39.1% had participated in continuing education on management of patients with class II/III obesity in the past 5 years. CONCLUSION: The majority of PCPs believe there is a need for additional education about MSWLI for patients with class II/III obesity. Future studies are needed to develop and compare the effectiveness of additional education and professional development around risks of contemporary BS, indications to consider referral for MSWLI, management and long-term follow-up of patients after BS.

Competency-based education in general surgery: Are Canadian residents ready?

Summary: Competency-based education (CBE) is currently being implemented by the Royal College of Physicians and Surgeons of Canada across all residency programs. This shift away from time-based residency is proposed to be the answer to maximize training opportunity in the era of work hour restrictions and growing concerns regarding accountability in medical education. A Web-based survey was conducted to obtain feedback from Canadian general surgery residents on their experience and perception of competence within core procedures, as well as attitudes toward CBE. A total of 244 residents completed the survey. For most procedures, more than 50% of residents felt they could perform the procedure with no guidance after completing 11-30 cases. Generally, residents were welcoming of CBE; however, medium-sized programs reported some concerns regarding inadequate exposure to cases and risk of training less well-rounded surgeons. This is valuable resident feedback for programs to consider during the implementation process.

Evaluating bowel enterotomy closures in simulated deep body cavities using the reversing half-hitch alternating post and square knots: a randomized controlled trial.

Background: Square knots can be difficult to construct in deep body cavities. The reversing half-hitch alternating post (RHAP) surgical knot has noninferior tensile strength and performance characteristics in deep body cavities. We compared the enterotomy repairs of novice learners in simulated deep body cavities using RHAP versus square knots after proficiency-based training. Methods: Undergraduate students were randomized to RHAP (n = 10) or square knot (n = 10) groups and trained to defined proficiency. They then performed hand-sewn enterotomy repairs of cadaveric porcine small bowels on flat surfaces and in simulated deep body cavities. We recorded time to knot-tying proficiency and to enterotomy repair, and burst pressures for the repair. Results: Mean time-to-proficiency in knot tying was equivalent between the RHAP and square knot groups (23 [standard deviation (SD) 3] v. 21 [SD 2] min, p = 0.33). Mean time for enterotomy repair in deep cavities was shorter for the RHAP group (16 [SD 2] min v. 21 [SD 1] min, p = 0.02). Mean burst pressures for enterotomy repair were equivalent on flat surfaces (128 [SD 41] v. 101 [SD 36] mm Hg, p = 0.31), and were significantly higher for the RHAP group in simulated deep body cavities (32 [SD 13] v. 105 [SD 37] mm Hg, p = 0.05). Conclusion: The RHAP knots appear to have superior performance versus square knots when tied in a deep body cavity by novice learners. Future work should focus on demonstrating the clinical relevance and broad utility of the RHAP knot in abdominal surgery. Both knot types should be taught to novice learners.

Contexte: L'exécution de noeuds plats peut être difficile dans les cavités corporelles profondes. Les noeuds de type demi-clé inversée alternée (RHAP, pour reversing halfhitch alternating post) ont une résistance à la traction et un rendement semblables à ceux des noeuds plats dans ces cavités. Nous avons comparé l'efficacité des noeuds plats et des noeuds de type RHAP réalisés par de nouveaux apprenants dans des cavités profondes simulées, après leur avoir enseigné les compétences nécessaires. Méthodes: Les étudiants de premier cycle ont été aléatoirement répartis en 2 groupes, soit le groupe RHAP (n = 10) et le groupe noeud plat (n = 10), et ont reçu une formation pour développer des compétences prédéfinies. Ils ont ensuite suturé à la main un intestin grêle provenant d'un cadavre de porc, sur une surface plane et à l'intérieur d'une cavité profonde simulée. Nous avons mesuré le temps nécessaire à l'exécution du noeud et à la suture complète de l'incision, de même que la pression que pouvait subir cette suture sans se rompre. Résultats: Le temps moyen d'exécution du noeud était semblable entre les groupes RHAP et noeud plat (23 min [écart type (E.T.) 3 min] c. 21 min [E.T. 2 min]; p = 0,33). Le temps moyen nécessaire à la suture de l'incision dans la cavité profonde était plus court dans le groupe RHAP (16 min [E.T. 2 min] c. 21 min [E.T. 1 min]; p = 0,02). La pression moyenne que pouvait subir la suture sans se rompre était comparable pour les sutures effectuées sur une surface plane (128 mm Hg [E.T. 41 mm Hg] c. 101 mm Hg [E.T. 36 mm Hg]; p = 0,31), mais était significativement plus élevée dans le groupe RHAP pour les sutures faites dans la cavité profonde (32 mm Hg [E.T. 13 mm Hg] c. 105 mm Hg [E.T. 37 mm Hg], p = 0,05). Conclusion: Les noeuds de type RHAP semblent avoir un rendement supérieur à celui des noeuds plats lorsqu'ils sont réalisés dans une cavité profonde par de nouveaux apprenants. Des études ultérieures devraient se pencher sur la pertinence clinique et l'utilité générale de ces noeuds en chirurgie abdominale. Les 2 types de noeuds devraient être enseignés aux nouveaux apprenants.

Patients eligible and referred for bariatric surgery in southeastern Ontario: Retrospective cohort study.

OBJECTIVE: To evaluate the proportion of eligible individuals, within one health region in Ontario, who were referred for publicly funded medical and surgical weight-loss interventions (MSWLI). DESIGN: A retrospective cohort study that used primary care data from the Canadian Primary Care Sentinel Surveillance Network (CPCSSN) and referral data from the Ontario Bariatric Network (OBN). SETTING: Primary care practices within southeastern Ontario that contribute data to CPCSSN. PARTICIPANTS: Patients with class II (body mass index [BMI] 35.0 to 39.9 kg/m2) or III (BMI ≥ 40 kg/m2) obesity who were eligible for referral to the OBN for MSWLI. MAIN OUTCOME MEASURES: Primary care data about patients within the CPCSSN database were linked to referral records within the OBN database using 3 indirect identifiers to determine the proportion of patients with class II and III obesity who were referred to the OBN for MSWLI. An adjusted multivariate logistic regression model was used to determine the most significant predictors of referral. RESULTS: Of the 87 276 patients within one health region in Ontario, 15 526 (17.8%) patients had class II or III obesity and were eligible for referral for MSWLI. Only 966 out of those 15 526 (6.2%) patients were actually referred for MSWLI. In the multivariate regression analysis, BMI had the strongest association with referral in terms of adjusted odds ratio (AOR), varying from 2.50 (95% CI 2.04 to 3.06) for a BMI of 40.0 to 44.9 kg/m2, to 5.15 (95% CI 4.21 to 6.30) for a BMI of 50.0 kg/m2 or greater. Referral was more likely for female than male patients (AOR = 2.18; 95% CI 1.86 to 2.57), those living rurally than for urban dwellers (AOR = 1.39; 95% CI 1.20 to 1.60), and those aged 30 to 39 (AOR = 1.61; 95% CI 1.24 to 2.09) and 40 to 49 (AOR = 1.53; 95% CI 1.18 to 1.98) compared with other age groups. CONCLUSION: Within one health region in Ontario, the referral rate of patients with class II and III obesity for MSWLI was low. Our findings highlight the need for further research to understand and address the barriers to referral of patients with class II and III obesity for MSWLI.

Optimizing resource utilization during proficiency-based training of suturing skills in medical students: a randomized controlled trial of faculty-led, peer tutor-led, and holography-augmented methods of teaching.

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.

Comparison of knot-tying proficiency and knot characteristics for square and reversing half hitch alternating-post surgical knots in a simulated deep body cavity among notice medical students.

BACKGROUND: Proficiency-based knot-tying curricula have been developed for square knots for medical students, but, to our knowledge, no such curriculum exists for the reverse half hitch alternating-post (RHAP) knot. We aimed to compare medical students' knot-tying proficiency, knot-tying self-confidence and final knot characteristics for RHAP and square knots in a simulated deep body cavity. METHODS: We performed a within-subject prospective crossover study of novice medical students who received 30 minutes of training in tying both RHAP and square knots. Participant performance was assessed via a knot-tying checklist, and knot configuration, tensile strength, tightness (loop circumference) and mechanism of failure were also assessed. Participants' self-reported confidence in knot tying was captured. RESULTS: Twenty-one students participated in the study. Mean scores on the knot-tying checklist were significantly higher for RHAP knots than for square knots (6.9 [standard deviation (SD) 2.1] v. 5.2 [SD 2.3], p < 0.01), and RHAP knots were significantly tighter than square knots (46.8 mm [SD 0.4 mm] v. 49.3 mm [SD 0.7 mm], p < 0.05). There were no differences between RHAP and square knots in correct knot configuration, breaking strength or mechanism of failure. Reverse half hitch alternating-post knots were easier to tie within a deep-body cavity, whereas square knots were easier to learn. CONCLUSION: Novice medical students were more proficient in tying RHAP knots than square knots in a simulated deep body cavity. Students were able to construct RHAP knots more securely and reported increased confidence in tying RHAP knots at depth compared to square knots.

CONTEXTE: Des programmes d'enseignement fondés sur la compétence dans l'exécution de nœuds chirurgicaux par les étudiants en médecine ont été créés pour les nœuds plats, mais autant que nous sachions, un tel programme n'existe pas pour le nœud de type demi-clé inversée alternée. Nous avons comparé les aptitudes d'exécution de nœuds et la confiance des étudiants en médecine, ainsi que les caractéristiques des nœuds résultants, pour les nœuds de type demi-clé inversée alternée et les nœuds plats, dans une simulation de cavité profonde. MÉTHODES: Nous avons réalisé une étude croisée prospective intra-sujet portant sur des étudiants en médecine débutants, qui ont reçu une formation de 30 minutes sur l'exécution de nœuds de type demi-clé inversée alternée et de nœuds plats. Le travail des participants a été évalué à l'aide d'une liste de vérification d'exécution des nœuds; la configuration des nœuds, la résistance à la traction, le serrage (circonférence de la boucle) et le mécanisme de défaillance ont aussi été évalués. La confiance en soi rapportée par les participants quant à leurs aptitudes d'exécution de nœuds a aussi été examinée. RÉSULTATS: Vingt-et-un étudiants ont pris part à cette étude. Les scores moyens de la liste de vérification d'exécution des nœuds étaient significativement plus élevés pour les nœuds de type demi-clé inversée alternée que pour les nœuds plats (6,9 [écart-type (É.T.) : 2,1] contre 5,2 [É.T. : 2,3], p < 0,01), et les nœuds demi-clé inversée alternée étaient significativement plus serrés que les nœuds plats (46,8 mm [É.T. : 0,4 mm] contre 49,3 mm [É.T. : 0,7 mm], p < 0,05). Aucune différence n'a été observée entre les 2 types de nœuds quant à la configuration, à la résistance à la traction et au mécanisme de défaillance. Les nœuds de type demi-clé inversée alternée étaient plus faciles à nouer dans une cavité profonde, mais la technique des nœuds plats était plus simple à apprendre. CONCLUSION: Les aptitudes des étudiants en médecine débutants pour l'exécution de nœuds de type demi-clé inversée alternée étaient supérieures à leurs aptitudes pour l'exécution de nœuds plats, lors d'une simulation de cavité profonde. Les étudiants ont pu réaliser des nœuds de type demi-clé inversée alternée plus solides et ont rapporté une confiance plus grande quant à l'exécution de ce type de nœuds que pour l'exécution de nœuds plats en profondeur.
