Consensus guidelines on the bedside assistant skills required in robotic surgery.

BACKGROUND: While bedside assistants play a critical role in many robotic operations, substantial heterogeneity remains in bedside assistant training pathways. As such, this study aimed to develop consensus guidelines for bedside assistant skills required for team members in robotic operations. METHODS: We designed a study using the Delphi process to develop consensus guidelines around bedside assistant skills. We generated an initial list of bedside assistant skills from the literature, training materials, and expert input. We selected experts for the Delphi process based on prior scholarship in the area of robotic bedside assistant education and experience facilitating robotic bedside assistant training. For each item, respondents specified which robotic team members should have the skill from a list of "basic" bedside assistants, "advanced" bedside assistants, surgeons, surgical technologists, and circulating nurses. We conducted two rounds of the Delphi process and defined 80% agreement as sufficient for consensus. RESULTS: Fourteen experts participated in two rounds of the Delphi process. By the end of the second round, the group had reached consensus on 253 of 305 items (83%). The group determined that "basic" bedside assistants should have 52 skills and that "advanced" bedside assistants should have 60 skills. The group also determined that surgeons should have 54 skills, surgical technologists should have 25 skills, and circulating nurses should have 17 skills. Experts agreed that all participants should have certain communication skills and basic knowledge of aspects of the robotic system. CONCLUSIONS: We developed consensus guidelines on the skills required during robotic surgery by bedside assistants and other team members using the Delphi process. These findings can be used to design training around bedside assistant skills and assess team members to ensure that each team member has the appropriate skills. Hospitals can also use these guidelines to standardize expectations for robotic team members.

Is it gossip or feedback? Surgical attendings' perceptions of gossip within residency.

OBJECTIVE: Gossip-evaluative talk about an absent third party-exists in surgical residency programs. Attending surgeons may engage in gossip to provide residents with feedback on performance, which may contribute to bias. Nevertheless, the perspectives of attending surgeons on gossip has not been studied. DESIGN: In this qualitative study, semi-structured interviews about gossip in surgical training were conducted with attending surgeons. We performed a reflexive thematic analysis of transcripts with a grounded theory approach to describe attendings' perceptions of their role in gossip within surgical residency. SETTING: Interviews were conducted from September 23, 2023, to November 27, 2023 via Zoom™. PARTICIPANTS: Eighteen surgery attendings associated with 7 surgical training programs were interviewed. RESULTS: Six themes were developed: 1) Attendings typically view gossip with a negative lens; thus, well-intended conversations about resident performance that meet the academic definition of gossip are not perceived as gossip; 2) Gossip can damage attendings' reputations as surgeons and educators; 3) Mitigating the negative impacts of gossip by maintaining accurate and objective standards of honest communication is hard; 4) Attendings express concerns about hearing other attendings' impressions of residents prior to formulating their own opinion; 5) The surgical hierarchy restricts the volume and content of gossip that reaches attendings, which may limit their knowledge of program culture; and 6) It is very difficult to mitigate gossip at the program level. Ultimately, attendings utilize gossip (e.g. triangulating their experience) with the goal of providing residents feedback. CONCLUSIONS: Defining important conversations about resident performance as gossip should not discourage these critically important conversations but rather underscore the importance of combating harmful gossip through 3 behaviors: 1) committing to objective communication; 2) limiting or reframing information about resident performance that is shared with attendings who have yet to formulate their own opinions; and 3) regulating gossip in particular high-stakes microenvironments (e.g. the operating room).

Vascular Anastomoses and Dissection: A Six-Part Simulation Curriculum for Surgical Residents.

Introduction: As surgical technologies grow, so too do demands on surgical trainees to master increasing numbers of skill sets. With the rise of endovascular surgery, trainees have fewer opportunities to practice open vascular techniques in the operating room. Simulation can bridge this gap. However, existing published open vascular simulation curricula are basic or based on expensive models. Methods: We iteratively developed an open vascular skills curriculum for second-year surgery residents comprising six 2-hour sessions. We refined the curriculum based on feedback from learners and faculty. The curriculum required skilled facilitators, vascular instruments, and tissue models. We evaluated the latest iteration with a survey and by assessing participants' technical skills using the Objective Structured Assessment of Technical Skills (OSATS) form. Results: Over the past 10 years, 101 residents have participated in the curriculum. Nine of 13 residents who participated in the latest curricular iteration completed the survey. All respondents rated the sessions as excellent and strongly agreed that they had improved their abilities to perform anastomoses with tissue and prosthetic. Facilitators completed 18 OSATS forms for residents in the fifth and sixth sessions of the latest iteration. Residents scored well overall, with a median 26.5 (interquartile range: 24-29) out of a possible score of 35, with highest scores on knowledge of instruments. Discussion: This simulation-based curriculum facilitates open vascular surgical skill acquisition among surgery residents. The curriculum allows residents to acquire critical vascular skills that are challenging to learn in an increasingly demanding operative setting.

An At-Home Laparoscopic Curriculum for Junior Residents in Surgery, Obstetrics/Gynecology, and Urology.

Introduction: Laparoscopic surgery requires significant training, and prior studies have shown that surgical residents lack key laparoscopic skills. Many educators have implemented simulation curricula to improve laparoscopic training. Given limited time for dedicated, in-person simulation center practice, at-home training has emerged as a possible mechanism by which to expand training and promote practice. There remains a gap in published at-home laparoscopic curricula employing embedded feedback mechanisms. Methods: We developed a nine-task at-home laparoscopic curriculum and an end-of-curriculum assessment following Kern's six-step approach. We implemented the curriculum over 4 months with first- to third-year residents. Results: Of 47 invited residents from general surgery, obstetrics/gynecology, and urology, 37 (79%) participated in the at-home curriculum, and 25 (53%) participated in the end-of-curriculum assessment. Residents who participated in the at-home curriculum completed a median of six of nine tasks (interquartile range: 3-8). Twenty-two residents (47%) responded to a postcurriculum survey. Of these, 19 (86%) reported that their laparoscopic skills improved through completion of the curriculum, and the same 19 (86%) felt that the curriculum should be continued for future residents. Residents who completed more at-home curriculum tasks scored higher on the end-of-curriculum assessment (p = .009 with adjusted R 2 of .28) and performed assessment tasks in less time (p = .004 with adjusted R 2 of .28). Discussion: This learner-centered laparoscopic curriculum provides guiding examples, spaced practice, feedback, and graduated skill development to enable junior residents to improve their laparoscopic skills in a low-stakes, at-home environment.

Online videos of robotic-assisted cholecystectomies: more harm than good?

BACKGROUND: Many surgeons use online videos to learn. However, these videos vary in content, quality, and educational value. In the setting of recent work questioning the safety of robotic-assisted cholecystectomies, we aimed (1) to identify highly watched online videos of robotic-assisted cholecystectomies, (2) to determine whether these videos demonstrate suboptimal techniques, and (3) to compare videos based on platform. METHODS: Two authors searched YouTube and a members-only Facebook group to identify highly watched videos of robotic-assisted cholecystectomies. Three members of the Society of American Gastrointestinal and Endoscopic Surgeons Safe Cholecystectomy Task Force then reviewed videos in random order. These three members rated each video using Sanford and Strasberg's six-point criteria for critical view of safety (CVS) scoring and the Parkland grading scale for cholecystitis. We performed regression to determine any association between Parkland grade and CVS score. We also compared scores between the YouTube and Facebook videos using a t test. RESULTS: We identified 50 videos of robotic-assisted cholecystectomies, including 25 from YouTube and 25 from Facebook. Of the 50 videos, six demonstrated a top-down approach. The remaining 44 videos received a mean of 2.4 of 6 points for the CVS score (SD = 1.8). Overall, 4 of the 50 videos (8%) received a passing CVS score of 5 or 6. Videos received a mean of 2.4 of 5 points for the Parkland grade (SD = 0.9). Videos on YouTube had lower CVS scores than videos on Facebook (1.9 vs. 2.8, respectively), though this difference was not significant (p = 0.09). By regression, there was no association between Parkland grade and CVS score (p = 0.13). CONCLUSION: Publicly available and closed-group online videos of robotic-assisted cholecystectomy demonstrated inadequate dissection and may be of limited educational value. Future work should center on introducing measures to identify and feature videos with high-quality techniques most useful to surgeons.

Comparing observed and preferred instruction in robotic surgery.

BACKGROUND: The unique setup of robotic surgery challenges the traditional instructional dynamic between surgical learners and teachers. Previous studies have posited difficulties such as reliance on observational learning and ease of takeover. However, we lack understanding of how these instructional challenges manifest and are perceived by learners. Improving instruction has the potential to optimize education and performance in robotic surgery. METHODS: In this qualitative study, we conducted robotic case observations and learner interviews focusing on instruction in robotic surgery. We deductively generated codes in a theory-informed manner after review of the instructional literature in surgery, medicine, and other fields. We applied these codes in a rigorous directed content analysis of field notes and transcripts to identify themes. RESULTS: Thirty-eight faculty, fellows, and residents participated in 10 robotic cases and 20 semistructured interviews. Observed practices on the basis of case observations differed substantially from preferred practices on the basis of interview data. Using 37 codes, we identified 4 main themes related to instruction in robotic surgery: contextualization, individualization, autonomy, and multimodality. We contrasted observed and preferred instruction in each of these areas to generate instructional considerations that may better align preferences and practices. CONCLUSIONS: We observed several suboptimal instructional practices that contradicted preferred ways of learning. We suggested robotic-specific instructional considerations such as using multimodality to promote active learning and to reduce ambiguity. We also provided considerations applicable to all types of surgery, such as to include rationale to promote learning consolidation and to frame operative steps to allow trainees to plan their participation.

Reimagining general surgery resident selection: Collaborative innovation through design thinking.

Introduction: The process by which surgery residency programs select applicants is complex, opaque, and susceptible to bias. Despite attempts by program directors and educational researchers to address these issues, residents have limited ability to affect change within the process at present. Here, we present the results of a design thinking brainstorm to improve resident selection and propose this technique as a framework for surgical residents to creatively solve problems and generate actionable changes. Methods: Members of the Collaboration of Surgical Education Fellows (CoSEF) used the design thinking framework to brainstorm ways to improve the resident selection process. Members participated in one virtual focus group focused on identifying pain points and developing divergent solutions to those pain points. Pain points and solutions were subsequently organized into themes. Finally, members participated in a second virtual focus group to design prototypes to test the proposed solutions. Results: Sixteen CoSEF members participated in one or both focus groups. Participants identified twelve pain points and 57 potential solutions. Pain points and solutions were grouped into the three themes of transparency, fairness, and applicant experience. Members subsequently developed five prototype ideas that could be rapidly developed and tested to improve resident selection. Conclusions: The design thinking framework can help surgical residents come up with creative ideas to improve pain points within surgical training. Furthermore, this framework can supplement existing quantitative and qualitative methods within surgical education research. Future work will be needed to implement the prototypes devised during our sessions and turn them into complete interventions. Key message: In this paper, we demonstrate the results of a resident-led design thinking brainstorm on improving resident selection in which our team identified twelve pain points in resident selection, ideated 57 solutions, and developed five prototypes for further testing. In addition to sharing our results, we believe design thinking can be a useful framework for creative problem solving within surgical education.

Comparing Peer and Faculty Feedback for Asynchronous Laparoscopic Skill Acquisition.

OBJECTIVE: Traditionally, expert surgeons have provided surgical trainees with feedback about their simulation performance, including for asynchronous practice. Unfortunately, innumerable time demands may limit experts' ability to provide feedback. It is unknown whether and how peer feedback is an effective mechanism to help residents acquire laparoscopic skill in an asynchronous setting. As such, we aimed to assess the effect of peer feedback on laparoscopic performance and determine how residents perceive giving and receiving peer feedback. DESIGN: We conducted a convergent mixed methods study. In the quantitative component, we randomized residents to receive feedback on home laparoscopic tasks from peers or faculty. We then held an end-of-curriculum, in-person laparoscopic assessment with members from both groups and compared performance on the in-person assessment between the groups. In the qualitative component, we conducted interviews with resident participants to explore experiences with feedback and performance. Three authors coded and rigorously reviewed interview data using a directed content analysis. SETTING: We performed this study at a single tertiary academic institution: the University of California, San Francisco. PARTICIPANTS: We invited 47 junior residents in general surgery, obstetrics-gynecology, and urology to participate, of whom 37 (79%) participated in the home curriculum and 25 (53%) participated in the end-of-curriculum assessment. RESULTS: Residents in the peer feedback group scored similarly on the final assessment (mean 70.7%; SD 16.1%) as residents in the faculty feedback group (mean 71.8%; SD 11.9%) (p = 0.86). Through qualitative analysis of interviews with 13 residents, we identified key reasons for peer feedback's efficacy: shared mental models, the ability to brainstorm and appreciate new approaches, and a low-stakes learning environment. CONCLUSIONS: We found that peer and faculty feedback led to similar performance in basic laparoscopy and that residents engaged positively with peer feedback, suggesting that peer feedback can be used when residents learn basic laparoscopy.

A "just in time" educational intervention for opioid overprescribing in dialysis access surgery.

BACKGROUND: Despite widespread efforts to combat the opioid epidemic, an ongoing contributor to opioid misuse remains post-operative opioid overprescribing by residents. The goal of this study was to evaluate the impact of a low-cost, reproducible "just in time" intervention on opioid prescribing in dialysis access operations. METHODS: Standardized opioid prescribing guidelines were emailed to residents on the vascular service on the first day of the rotation. Opioid prescriptions were reviewed for four years before and one year after this intervention. Wilcoxon rank-sum test and tests of proportions were used to compare groups. RESULTS: Overall, 299 patients underwent dialysis access procedures. There was a decrease in patients discharged with opioids following the intervention from 58% to 36% (p â€‹= â€‹0.003). For patients prescribed opioids, the median quantity decreased from 90 to 45 oral morphine equivalents (p â€‹= â€‹0.03). CONCLUSIONS: This low-cost and timely learning intervention may be a useful adjunct to reduce post-operative opioid prescriptions.

"Doing well": Intraoperative entrustable professional activity assessments provided limited technical feedback.

Background: Entrustable Professional Activities (EPAs) allow for the assessment of specific, observable, essential tasks in medical education. Since being developed in non-surgical fields, EPA assessments have been implemented in surgery to explore intraoperative entrustment. However, assessment burden is a significant problem for faculty, and it is unknown whether EPA assessments enable formative technical feedback. EPAs' formative utility could inform how surgical programs facilitate technical feedback for trainees. We aimed to assess the extent to which narrative comments provided through the Fellowship Council (FC) EPA assessments contained technical feedback. Methods: The FC previously collected EPA assessments for subspecialty surgical fellows from September 2020 to October 2022. Two raters reviewed assessments' narrative comments for inclusion of each skill area that makes up part of the Objective Structured Assessment of Technical Skills (OSATS). A third rater reconciled discrepant ratings. Results: During the study period, there were 3302 completed EPA assessments, including 1191 fellow self-assessments, 1124 faculty assessments, and 987 assessments without an identified assessor role. We found that assessments' narrative comments related to a median of two of the seven OSATS areas (IQR:1-2). There were no comments relevant to any of the seven OSATS areas in 16.0 % of all assessments. Conclusions: In this review of narrative comments for EPA assessments from the FC, we found that limited technical feedback of the kind included in the OSATS was provided in many assessments. These results suggest benefit to adjusting the EPA form, enhancing faculty development, or continuing additional types of targeted technical assessment intraoperatively. Key message: This analysis of narrative comments from fellowship EPA assessments showed that many assessments included limited technical feedback. To allow for continued technical feedback for fellows, these results highlight the need for further refinements of the EPA assessment form, additional faculty development, or ongoing use of other types of technical assessment.

Confronting new challenges: Faculty perceptions of gaps in current laparoscopic curricula in a changing training landscape.

Background: Opportunities for residents to develop laparoscopic skills have decreased with the rise in robotic operations and the development of complex, subspecialized laparoscopic operations. Given the changing training landscape, this study aimed to identify laparoscopic surgeons' perceptions of gaps in current laparoscopic skills in general surgery, obstetrics-gynecology, and urology residency programs. Methods: Laparoscopic surgeons who operate with residents participated in semi-structured interviews. Questions addressed expectations for resident proficiency, deficits in laparoscopic surgical skills, and barriers to learning and teaching. Two authors independently coded de-identified transcripts followed by a conventional content analysis. Results: Fourteen faculty members from thirteen subspecialties participated. Faculty identified three main areas to improve laparoscopic training across specialties: foundational knowledge, technical skills, and cognitive skills. They also recognized an overarching opportunity to address faculty development. Conclusions: This qualitative study highlighted key deficiencies in laparoscopic training that have emerged in the current, changing era of minimally invasive surgery. Key message: This qualitative study identified laparoscopic educators' perceptions of deficiencies in laparoscopic training. Findings emphasized the importance of incorporating high quality educational practices to optimize training in the current changing landscape of laparoscopic surgery.

Home practice for robotic surgery: a randomized controlled trial of a low-cost simulation model.

Pre-operative simulated practice allows trainees to learn robotic surgery outside the operating room without risking patient safety. While simulation practice has shown efficacy, simulators are expensive and frequently inaccessible. Cruff (J Surg Educ 78(2): 379-381, 2021) described a low-cost simulation model to learn hand movements for robotic surgery. Our study evaluates whether practice with low-cost home simulation models can improve trainee performance on robotic surgery simulators. Home simulation kits were adapted from those described by Cruff (J Surg Educ 78(2): 379-381, 2021). Hand controllers were modified to mimic the master tool manipulators (MTMs) on the da Vinci Skills Simulator (dVSS). Medical students completed two da Vinci exercises: Sea Spikes 1 (SS1) and Big Dipper Needle Driving (BDND). They were subsequently assigned to either receive a home simulation kit or not. Students returned two weeks later and repeated SS1 and BDND. Overall score, economy of motion, time to completion, and penalty subtotal were collected, and analyses of covariance were performed. Semi-structured interviews assessed student perceptions of the robotic simulation experience. Thirty-three medical students entered the study. Twenty-nine completed both sessions. The difference in score improvement between the experimental and control groups was not significant. In interviews, students provided suggestions to increase fidelity and usefulness of low-cost robotic home simulation. Low-cost home simulation models did not improve student performance on dVSS after two weeks of at-home practice. Interview data highlighted areas to focus future simulation efforts. Ongoing work is necessary to develop low-cost solutions to facilitate practice for robotic surgery and foster more inclusive and accessible surgical education.

Experience matters for robotic assistance: an analysis of case data.

Many robotic procedures require active participation by assistants. Most prior work on assistants' effect on outcomes has been limited in procedural focus and scope, with studies reporting differing results. Knowing how assistant experience affects operating room time could inform operating room case scheduling and provide an impetus for additional assistant training. As such, this retrospective cohort study aimed to determine the association between assistant experience and operating room time for 2291 robotic-assisted operations performed from 2016 to 2022 at our institution. Linear regression showed a significant association between the presence of a junior resident and increased case length differential with an increase of 26.9 min (p = 0.01). There were no significant associations between the presence of a senior resident (p = 0.52), presence of a fellow (p = 0.20), or presence of a physician assistant (p = 0.43) and case length differential. The finding of increased operating room time in the presence of a junior resident during robotic cases supports consideration of the adoption of formal assistant training programs for residents to improve efficiency.

Therapeutic Reasoning: A Conceptual Challenge for Medical Students' Surgical Clerkship.

Issue: Medical students' transition between pre-clinical and clinical environments can be jarring. Unclear expectations, disconnect between the pre-clinical and clinical environments, and feelings of exclusion from the team all negatively influence clerkship experiences. These difficulties are magnified on interventional-based clerkships due to the central role of therapeutic reasoning. Therapeutic reasoning is the process by which clinicians review and select treatments for their patients. Surgical therapeutic reasoning is challenging and infrequently addressed explicitly in the pre-clinical curriculum. This contributes to confusion among medical students as they transition from pre-clinical to clinical learning. Evidence: Multiple studies have identified challenges to medical students' transition to clinical clerkships. Prior authors have outlined numerous barriers to successful medical student integration to clinical teams, including surgical teams. Studies that have assessed students' perceptions of their transition to a clinical setting noted poor understanding of treatment decisions as a source of anxiety. Additionally, of particular importance to medical student team learning is their assimilation into the "communities of clinical practice," groups of healthcare professionals who form teams with which students rotate. Surgeons have distinct approaches to the clinical process compared with non-interventionalists, particularly related to post-diagnostic involvement in care and performing diagnostic workup and treatment concurrently. Knowledge of these approaches is important for integration into surgical teams. Implications: An understanding of interventional therapeutic reasoning is critical to allow for medical students' team integration on surgical and interventional clerkships. By incorporating education involving these concepts during the orientation period prior to students' transition to surgical clerkships, we can help students modify traditional mental frameworks to effectively evaluate, present, and select appropriate interventions for patients. Such education should include a didactic introduction to therapeutic reasoning, interactive discussion with surgeons, and exercises for students to practice skills. This will maximize learning opportunities and clerkship experience.

Virtual Interviews: Assessing How Expectations Meet Reality.

OBJECTIVE: This study aimed to determine the post-matriculation perceptions of interns and faculty who participated in the 2020-2021 virtual interview process and how their expectations of the program and the applicants, respectively, aligned with reality. DESIGN, SETTING, AND PARTICIPANTS: Published surveys on virtual interviewing were reviewed and modified to design two surveys, for interns and for faculty who interviewed. Interns and faculty members from the Departments of Surgery and Medicine at one institution who participated in the 2020-2021 virtual interview process completed the surveys four to six months after the start of the academic year. Following survey completion, surgical interns from the same application cycle participated in one in-person focus group nine months after the start of the academic year to clarify points raised in the surveys. RESULTS: Forty-six interns and faculty members responded to the survey (subgroup response rates ranging from 13-30%) and ten interns participated in the focus group (participation rate 100%). Most faculty and intern participants found that expectations formed during virtual interviews were accurate. However, our respondents noted limitations to virtual interviews that reduced their usefulness, including challenges with unnatural social interactions, understanding city fit, and getting a sense of resident and program culture. Participants provided possible solutions to address these challenges. CONCLUSIONS: Overall, this mixed-methods study at a single institution found that perceptions from virtual interviews were generally accurate but with some limitations. We describe several opportunities to improve the virtual interview process and optimize the application experience.

Assessment of Surgeon Performance of Advanced Open Surgical Skills Using a Microskills-Based Novel Curriculum.

Importance: The increase in minimally invasive surgical procedures has eroded exposure of general surgery residents to open operations. High-fidelity simulation, together with deliberate instruction, is needed for advanced open surgical skill (AOSS) development. Objective: To collect validity evidence for AOSS tools to support a shared model for instruction. Design, Setting, and Participants: This prospective cohort study included postresidency surgeons (PRSs) and second-year general surgery residents (R2s) at a single academic medical center who completed simulated tasks taught within the AOSS curriculum between June 1 and October 31, 2021. Exposures: The AOSS curriculum includes 6 fine-suture and needle handling tasks, including deep suture tying (with and without needles) and continuous suturing using the pitch-and-catch and push-push-pull techniques (both superficial and deep). Teaching and assessment are based on specific microskills using a 3-dimensional printed iliac fossa model. Main Outcomes and Measures: The PRS group was timed and scored (5-point Likert scale) on 10 repetitions of each task. Six months after receiving instruction on the AOSS tasks, the R2 group was similarly timed and scored. Results: The PRS group included 14 surgeons (11 male [79%]; 8 [57%] attending surgeons) who completed the simulation; the R2 group, 9 surgeons (5 female [55%]) who completed the simulation. Score and time variability were greater for the R2s compared with the PRSs for all tasks. The R2s scored lower and took longer on (1) deep pitch-and-catch suturing (69% of maximum points for a mean [SD] of 142.0 [31.7] seconds vs 77% for a mean [SD] of 95.9 [29.4] seconds) and deep push-push-pull suturing (63% of maximum points for a mean [SD] of 284.0 [72.9] seconds vs 85% for a mean [SD] of 141.4 [29.1] seconds) relative to the corresponding superficial tasks; (2) suture tying with a needle vs suture tying without a needle (74% of maximum points for a mean [SD] of 64.6 [19.8] seconds vs 90% for a mean [SD] of 54.4 [15.6] seconds); and (3) the deep push-push-pull vs pitch-and-catch techniques (63% of maximum points for a mean [SD] of 284.0 [72.9] seconds vs 69% of maximum points for a mean [SD] of 142.0 [31.7] seconds). For the PRS group, time was negatively associated with score for the 3 hardest tasks: superficial push-push-pull (ρ = 0.60; P = .02), deep pitch-and-catch (ρ = 0.73; P = .003), and deep push-push-pull (ρ = 0.81; P < .001). For the R2 group, time was negatively associated with score for the 2 easiest tasks: suture tying without a needle (ρ = 0.78; P = .01) and superficial pitch-and-catch (ρ = 0.79; P = .01). Conclusions and Relevance: The findings of this cohort study offer validity evidence for a novel AOSS curriculum; reveal differential difficulty of tasks that can be attributed to specific microskills; and suggest that position on the surgical learning curve may dictate the association between competency and speed. Together these findings suggest specific, actionable opportunities to guide instruction of AOSS, including which microskills to focus on, when individual rehearsal vs guided instruction is more appropriate, and when to focus on speed.

Evidence-based Guidelines on the Use of Virtual Surgical Education Pertaining to the Domains of Cognition and Curriculum, Psychomotor Skills Training, and Faculty Development and Mentorship.

OBJECTIVE: To identify, categorize, and evaluate the quality of literature, and to provide evidence-based guidelines on virtual surgical education within the cognitive and curricula, psychomotor, and faculty development and mentorship domains. SUMMARY OF BACKGROUND DATA: During the coronavirus disease 2019 pandemic, utilizing virtual learning modalities is expanding rapidly. Although the innovative methods must be considered to bridge the surgical education gap, a framework is needed to avoid expansion of virtual education without proper supporting evidence in some areas. METHODS: The Association for Surgical Education formed an ad-hoc research group to evaluate the quality and methodology of the current literature on virtual education and to build evidence-based guidelines by utilizing the SiGN methodology. We identified patient/problem-intervention-comparison-outcome-style questions, conducted systematic literature reviews using PubMed, EMBASE, and Education Resources information Center databases. Then we formulated evidence-based recommendations, assessed the quality of evidence using Grading of Recommendations, Assessment, Development, and Evaluation, Newcastle-Ottawa Scale for Education, and Kirkpatrick ratings, and conducted Delphi consensus to validate the recommendations. RESULTS: Eleven patient/problem-intervention-comparison-outcome-style questions were designed by the expert committees. After screening 4723 articles by the review committee, 241 articles met inclusion criteria for full article reviews, and 166 studies were included and categorized into 3 domains: cognition and curricula (n = 92), psychomotor, (n = 119), and faculty development and mentorship (n = 119). Sixteen evidence-based recommendations were formulated and validated by an external expert panel. CONCLUSION: The evidence-based guidelines developed using SiGN methodology, provide a set of recommendations for surgical training societies, training programs, and educators on utilizing virtual surgical education and highlights the area of needs for further investigation.

Computed tomography angiography is associated with low added utility for detecting clinically relevant vascular injuries among patients with extremity trauma.

BACKGROUND: Extremity CT angiography (CTA) is frequently used to assess for vascular injury among patients with extremity trauma. The injured extremity index (IEI), defined as the ratio of systolic occlusion pressure between injured and uninjured extremities, has been implemented to screen patients being considered for CTA. Physical examination together with IEI is extremely sensitive for significant extremity vascular injury. Unfortunately, IEI cannot always be calculated. This study aimed to determine whether patients with normal pulse examinations and no hard signs of vascular injury benefitted from further imaging with CTA. We hypothesized that CTA has become overused among patients with extremity trauma, as determined by the outcome of vascular abnormalities that underwent vascular intervention but were missed by physical examination. METHODS: The charts of traumatically injured patients who underwent extremity CTA were retrospectively reviewed. This study was performed at a level 1 trauma center for patients who presented as trauma activations from September 1, 2019 to September 1, 2020. RESULTS: One hundred and thirty-six patients with 167 injured limbs were included. Eight limbs (4.8%) underwent an open vascular operation, whereas five limbs (3.0%) underwent an endovascular procedure. One of the 167 limbs (0.6%) had a vascular injury seen on CTA and underwent intervention that was not associated with a pulse abnormality or hard signs of vascular injury. This patient presented in a delayed fashion after an initially normal IEI and examination. Proximity injuries and fractures alone were not highly associated with vascular injuries. DISCUSSION: Many patients with normal pulse examination and no hard signs of vascular injury underwent CTA; the vast majority of these patients did not then have a vascular intervention. Given the consequences of missed vascular injuries, further work is required to prospectively assess the utility of CTA among patients with extremity trauma. LEVEL OF EVIDENCE: III.
