RESUMO
OBJECTIVE: The purpose of this study was to describe management and outcomes from a contemporary cohort of children with Wilms tumor complicated by inferior vena caval thrombus. BACKGROUND: The largest series of these patients was published almost 2 decades ago. Since then, neoadjuvant chemotherapy has been commonly used to manage these patients, and outcomes have not been reported. METHODS: Retrospective review of 19 North American centers between 2009 and 2019. Patient and disease characteristics, management, and outcomes were investigated and analyzed. RESULTS: Of 124 patients, 81% had favorable histology (FH), and 52% were stage IV. IVC thrombus level was infrahepatic in 53 (43%), intrahepatic in 32 (26%), suprahepatic in 14 (11%), and cardiac in 24 (19%). Neoadjuvant chemotherapy using a 3-drug regimen was administered in 82% and postresection radiation in 90%. Thrombus level regression was 45% overall, with suprahepatic level showing the best response (62%). Cardiopulmonary bypass (CPB) was potentially avoided in 67%. The perioperative complication rate was significantly lower after neoadjuvant chemotherapy [(25%) vs upfront surgery (55%); P =0.005]. CPB was not associated with higher complications [CPB (50%) vs no CPB (27%); P =0.08]. Two-year event-free survival was 93% and overall survival was 96%, higher in FH cases (FH 98% vs unfavorable histology/anaplastic 82%; P =0.73). Neither incomplete resection nor viable thrombus cells affected event-free survival or overall survival. CONCLUSIONS: Multimodal therapy resulted in excellent outcomes, even with advanced-stage disease and cardiac extension. Neoadjuvant chemotherapy decreased the need for CPB to facilitate resection. Complete thrombectomy may not always be necessary.

Wilms tumor (WT) is the most common renal malignancy in children. Children with favorable histology WT achieve survival rates of over 90%. Twelve percent of patients present with metastatic disease, most commonly to the lungs. The presence of a pleural effusion at the time of diagnosis of WT may be noted on staging imaging; however, minimal data exist regarding the significance and prognostic importance of this finding. The objectives of our study are to identify the incidence of pleural effusions in patients with WT, and to determine the potential impact on oncologic outcomes. A multi-institutional retrospective review was performed from January 2009 to December 2019, including children with WT and a pleural effusion on diagnostic imaging treated at Pediatric Surgical Oncology Research Collaborative (PSORC) participating institutions. Of 1259 children with a new WT diagnosis, 94 (7.5%) had a pleural effusion. Patients with a pleural effusion were older than those without (median 4.3 vs 3.5 years; P = .004), and advanced stages were more common (local stage III 85.9% vs 51.9%; P < .0001). Only 14 patients underwent a thoracentesis for fluid evaluation; 3 had cytopathologic evidence of malignant cells. Event-free and overall survival of all children with WT and pleural effusions was 86.2% and 91.5%, respectively. The rate and significance of malignant cells present in pleural fluid is unknown due to low incidence of cytopathologic analysis in our cohort; therefore, the presence of an effusion does not appear to necessitate a change in therapy. Excellent survival can be expected with current stage-specific treatment regimens.

OBJECTIVE: To investigate the steps faculty surgeons take upon experiencing intraoperative error and synthesize these actions to offer a framework for coping with errors. BACKGROUND: While intraoperative errors are inevitable, formal training in error recovery is insufficient and there are no established curricula that teach surgeons how to deal with the intraoperative error. This is problematic because insufficient error recovery is detrimental to both patient outcomes and surgeon psychological well-being. METHODS: We conducted a thematic analysis. One-hour in-depth semistructured interviews were conducted with faculty surgeons from 3 hospitals. Surgeons described recent experiences with intraoperative error. Interviews were transcribed and coded. Analysis allowed for development of themes regarding responses to errors and coping strategies. RESULTS: Twenty-seven surgeons (30% female) participated. Upon completion of the analysis, themes emerged in 3 distinct areas: (1) Exigency, or a need for training surgical learners how to cope with intraoperative errors, (2) Learning, or how faculty surgeons themselves learned to cope with intraoperative errors, and (3) Responses, or how surgeons now handle intraoperative errors. The latter category was organized into the STOPS framework: Intraoperative errors could produce STOPS: Stop, Talk to your Team, Obtain Help, Plan, Succeed. CONCLUSIONS AND RELEVANCE: This study provides both novel insight into how surgeons cope with intraoperative errors and a framework that may be of great use to trainees and faculty alike.

INTRODUCTION: Physician burnout has been demonstrated at high rates among surgeons. Research has shown that physicians experiencing burnout have higher rates of depression, substance abuse, attrition, and medical errors. Surgical culture often promotes self-reliance; however, lacking social connections may worsen burnout. Therefore, we aimed to determine if struggling to develop a professional or personal community is associated with worsened burnout in surgeons. METHODS: We conducted a survey of surgical residents and faculty at seven institutions in the United States in the spring of 2021. Variables measured included mentorship experience, presence of a social community outside work, burnout levels (Professional Fulfillment Index [PFI], 15: high professional fulfillment, 75: low professional fulfillment), average weekly hours worked over the previous 2 mo, and demographics (race, gender, and role: faculty or resident). RESULTS: A total of 218 participants completed the survey (50% residents and 54% male). Participants' PFI scores were an average of 36.29/75, indicating poor professional fulfillment (standard deviation [SD] = 11.80). A multiple linear regression revealed that struggling to find a mentor (ß = 0.20, P = 0.004) and not having a social community exterior to the hospital (ß = -0.25, P < 0.001) were independently associated with significantly higher PFI scores (P < 0.001, R2 = 0.13). Gender, race, role, and hours worked were not associated with the PFI score. CONCLUSIONS: Struggling to find a mentor and a lack of social community outside of work are associated with higher levels of burnout in this multi-institutional study. These findings suggest that targeting an improved support for building professional and personal relationships may be a strategy for improving burnout levels in both faculty and resident surgeons.

OBJECTIVES: Peripheral intravenous (IV) cannulation is the most common procedure performed in the emergency department (ED). Elastic tourniquets (ETs) and blood pressure cuffs (BPCs) are frequently used for venodilation. Although BPCs lead to increased venodilation and decreased compressibility, it is unclear whether this translates into a meaningful patient-centered outcome. This study aimed to determine whether one method is superior for success on the first attempt. METHODS: This was a prospective, single-blinded, randomized controlled trial in the ED of a tertiary care center. A convenience sample of adult patients was randomly assigned to an ET or BPC with a cover concealing the type of tourniquet. The primary outcome was success rate on the first attempt. Secondary outcomes were number of attempts, number of providers, and rate of rescue techniques. RESULTS: Of the 121 patients enrolled, 119 qualified for analysis. In the ET group, 42 of 59 patients (71%) had successful IV cannulation on first attempt compared with 43 of 60 (72%) in the BPC group (Pâ¯=â¯.95). The number of attempts (Pâ¯=â¯.87), number of nurses (Pâ¯=â¯.67), and use of rescue techniques (Pâ¯=â¯.32) did not differ significantly. A history of difficult IV access and site other than the antecubital vein were associated with decreased success. CONCLUSIONS: ETs and BPCs performed similarly in providing venodilation for successful peripheral IV cannulation. History of difficult IV access and IV site are important factors in determining the likelihood of success.

OBJECTIVE: Video-based performance assessments provide essential feedback to surgical residents, but in-person and remote video-based assessment by trained proctors incurs significant cost. We aimed to determine the reliability, accuracy, and difficulty of untrained attending staff surgeon raters completing video-based assessments of a basic laparoscopic skill. Secondarily, we aimed to compare reliability and accuracy between 2 different types of assessment tools. DESIGN: An anonymous survey was distributed electronically to surgical attendings via a national organizational listserv. Survey items included demographics, rating of video-based assessment experience (1â¯=â¯have never completed video-based assessments, 5â¯=â¯often complete video-based assessments), and rating of favorability toward video-based and in-person assessments (0â¯=â¯not favorable, 100â¯=â¯favorable). Participants watched 2 laparoscopic peg transfer performances, then rated each performance using an Objective Structured Assessment of Technical Skill (OSATS) form and the McGill Inanimate System for Training and Evaluation of Laparoscopic Skills (MISTELS). Participants then rated assessment completion ease (1â¯=â¯Very Easy, 5â¯=â¯Very Difficult). SETTING: National survey of practicing surgeons. PARTICIPANTS: Sixty-one surgery attendings with experience in laparoscopic surgery from 10 institutions participated as untrained raters. Six experienced laparoscopic skills proctors participated as expert raters. RESULTS: Inter-rater reliability was substantial for both OSATS (kâ¯=â¯0.75) and MISTELS (kâ¯=â¯0.85). MISTELS accuracy was significantly higher than that of OSATS (κ: MISTELSâ¯=â¯0.18, 95%CIâ¯=â¯[0.06,0.29]; OSATSâ¯=â¯0.02, 95%CIâ¯=â¯[-0.01,0.04]). While participants were inexperienced with completing video-based assessments (medianâ¯=â¯1/5), they perceived video-based assessments favorably (meanâ¯=â¯73.4) and felt assessment completion was "Easy" on average. CONCLUSIONS: We demonstrate that faculty raters untrained in simulation-based assessments can successfully complete video-based assessments of basic laparoscopic skills with substantial inter-rater reliability without marked difficulty. These findings suggest an opportunity to increase access to feedback for trainees using video-based assessment of fundamental skills in laparoscopic surgery.

BACKGROUND: Percutaneous ethanol ablation has emerged as a treatment for recurrent papillary thyroid carcinoma in the lateral neck after compartment-oriented therapeutic lymphadenectomy. However, the safety and utility of percutaneous ethanol ablation as a primary treatment modality for lateral neck metastases remains undefined. We aimed to investigate long-term outcomes of percutaneous ethanol ablation of lateral neck papillary thyroid carcinoma recurrence both with and without prior lymphadenectomy. METHODS: We conducted a retrospective study of patients with lateral neck papillary thyroid carcinoma treated with percutaneous ethanol ablation from 2013 to 2018. Patient characteristics, disease volume, morbidity, and recurrence (development of new lymphadenopathy within a percutaneous ethanol ablation-treated nodal compartment) were assessed. RESULTS: We identified 117 patients who underwent percutaneous ethanol ablation for papillary thyroid carcinoma lateral neck metastases-67 (57%) had a prior lateral neck dissection. Median follow-up after percutaneous ethanol ablation was 5.5 years (interquartile range 3.1-7.5). On average, 1.4 lymph nodes (range: 1-6) were treated. Three patients (3%) developed transient nerve-related complications after percutaneous ethanol ablation. Of 15 patients who underwent lateral neck dissection after percutaneous ethanol ablation (including patients undergoing repeat lateral neck dissection), dissection was "difficult" in 8 (53%) (7 of whom had previously undergone lateral neck dissection), and 4 (27%) developed complications (transient nerve dysfunction = 3, lymphatic leak = 1). Thirty-three patients (28%) developed recurrent papillary thyroid carcinoma. No difference in recurrence was seen between patients who did or did not undergo pre-percutaneous ethanol ablation lateral neck dissection (no pre-percutaneous ethanol ablation lateral neck dissection: 24%, pre-percutaneous ethanol ablation lateral neck dissection, 31%; hazard ratio = 1.27, 95% confidence interval 0.62-2.58; P = .514). CONCLUSION: Percutaneous ethanol ablation may be a safe primary treatment modality for papillary thyroid carcinoma lateral neck nodal recurrence in selected patients with low-volume nodal disease.

INTRODUCTION: Much attention and effort are devoted to general surgery residency applicant interview strategies and ranking. However, few interview strategies are positively associated with applicant communication performance. The purpose of this study was to assess the potential of a LEGO-based communication assessment and a standardized patient-based emotional intelligence assessment to serve as an indicator for communication and interpersonal skills among peers in residency. METHODS: We examined general surgery residents who interviewed virtually at our institution in 2021-2022, then matriculated in 2022-2023. Residents' LEGO-based communication and emotional intelligence interview assessments were evaluated for associations with peer evaluations in intern year. A regression analysis was conducted testing the association between each assessment and peer-evaluation metrics, controlling for resident track (preliminary, categorical). RESULTS: Performance on LEGO-based communication assessments was significantly associated with peer evaluation of cross-cover performance (B = 0.09, standard error 0.044, 95% confidence interval 0.001-0.187, P = .048), whereas emotional intelligence scores had no significant association (P = .155). In contrast, performance on the LEGO-based communication assessments were associated with peer evaluations for desirability as a coworker (B = 0.098, standard error 0.038, 95% confidence interval 0.017-0.178, P = .021), whereas emotional intelligence scores were negatively associated with desirability as a coworker (B = -0.255, standard error 0.107, 95% confidence interval -0.482 to -0.029], P = .029). CONCLUSION: Although LEGO-based communication assessments before residency are associated with better resident peer evaluations 1 year into residency, our emotional intelligence applicant assessment during recruitment did not provide clear insight into resident performance. Future research should consider the ability of standardized assessments to predict performance.
RESUMO
BACKGROUND: Although most general surgery residency interviews remain virtual, the effect of this format remains understudied. Single-institution data have shown an increase in the number of applications received and interviews conducted with virtual interviewing but no change in the geographic backgrounds of interviewed or matched applicants. This study sought to compare national trends in geographic characteristics of general surgery applicants, interviewed applicants, and matched applicants between in-person and virtual application cycles. STUDY DESIGN: A retrospective review of 7 general surgery residency programs from application years 2016-2019 (in-person) and 2020-2021 (virtual) was conducted. Data collected included birth year, sex, race, medical school state, and contact location at the time of application. Data were analyzed using generalized mixed effects linear models. RESULTS: A total of 52,742 applicants, 4,550 interviewed applicants, and 329 matched applicants were included. During virtual application cycles, there were no increases in the average number of applicants (P = .25), interviewed applicants (P = .36), or matched (P = .84) applicants per year. Virtual cycles were associated with a larger proportion of interviews conducted with applicants from out-of-state medical schools (P < .01) and listing out-of-state contact locations (P < .01) compared with in-person application cycles. There were no significant geographic differences in matched applicants between virtual and in-person application cycles. CONCLUSION: Virtual application cycles had greater geographic diversity among interviewed applicants. However, similar differences were not seen in the geographic diversity of matched applicants. Additional efforts should focus on why no changes in the geographic diversity of matched applicants were identified.

PURPOSE: Supervisors may be prone to implicit (unintentional) bias when granting procedural autonomy to trainees due to the subjectivity of autonomy decisions. The authors aimed to conduct a systematic review and meta-analysis to assess the differences in perceptions of procedural autonomy granted to physician trainees based on gender and/or race. METHOD: MEDLINE, Embase, CENTRAL, Scopus, and Web of Science were searched (search date: January 5, 2022) for studies reporting quantitative gender- or race-based differences in perceptions of procedural autonomy of physician trainees. Reviewers worked in duplicate for article selection and data abstraction. Primary measures of interest were self-reported and observer-rated procedural autonomy. Meta-analysis pooled differences in perceptions of procedural autonomy based on trainee gender. RESULTS: The search returned 2,714 articles, of which 16 were eligible for inclusion. These reported data for 6,109 trainees (median, 90 per study) and 2,763 supervisors (median, 54 per study). No studies investigated differences in perceptions of autonomy based on race. In meta-analysis of disparities between genders in autonomy ratings (positive number favoring female trainees), pooled standardized mean differences were -0.12 (95% confidence interval [CI], -0.19 to -0.04; P = .003; n = 10 studies) for trainee self-rated autonomy and -0.05 (95% CI, -0.11 to 0.01; P = .07; n = 9 studies) for supervisor ratings of autonomy. CONCLUSIONS: Limited evidence suggests that female trainees perceived that they received less procedural autonomy than did males. Further research exploring the degree of gender- and race-based differences in procedural autonomy, and factors that influence these differences is warranted.

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.
RESUMO
OBJECTIVE: Racial and gender biases exist within academic surgery; bias negatively impacts patient care, reimbursement, student training, and staff retention. Few studies have investigated the potential for bias in surgical fellowship recruitment. We aimed to compare the racial and gender diversity at our hepatopancreatobiliary (HPB) surgery fellowship program to nationwide standards. We further aimed to investigate differences in the demographics of resident interviewees versus matriculants to our HPB fellowship. DESIGN: Retrospective review. SETTING: North American HPB fellowship training programs. PARTICIPANTS: Mayo Clinic's HPB surgery fellowship interviewees and North American HPB surgery fellowship graduates from 2013 to 2020. RESULTS: When compared to general surgery residency graduates during the study period (in 2019), a lower proportion of North American HPB surgery fellowship graduates were female (26% HPB fellowship graduates vs. 43.1% residents, pâ¯=â¯0.005), with no difference in proportion of racially under-represented in medicine (rURM) HPB fellowship graduates (10.7%) compared to rURM proportion of general surgery residents nationally (14.5%). There was an upward trend in female representation among North American HPB fellowship graduates from 11% in 2013 to 32% in 2020, but proportions of rURM HPB fellows remained steadily low. When comparing HPB interviewees at our institution to national general surgery residents, no differences were observed in proportions of female (34.4% interviewees vs. 43.1% residents, pâ¯=â¯0.17) or rURM (intervieweesâ¯=â¯6.8%, residentsâ¯=â¯14.5%, pâ¯=â¯0.09) applicants. Additionally, there was no significant difference between the proportion of female or rURM interviewees and matriculants to our HPB program. CONCLUSIONS: While fewer female graduating surgeons are pursuing HPB fellowship training than male graduates, this gender gap has narrowed over time. In contrast, the national percentage of rURM HPB fellowship graduates has remained low, mirroring stagnant proportions of rURM surgical residency graduates. When comparing HPB fellowship interviewees at our own institution to North American fellowship graduates, we observed similar proportions of female interviewees but lower proportions of rURM interviewees. Locally, these data will drive process change toward more intentional examination of our interview selection process. Nationally, more work is needed to increase the racial diversity of surgical residency and fellowship trainees to best reflect and serve our diverse patient populations.

We are the multi-institutional organization known as the Collaboration of Surgical Education Fellows (CoSEF). We've collectively reflected on our range of experiences across the country and identified 3 principles which promote a successful intern experience: (1) Own your patients; (2) Treat people like people; and (3) Take care of yourself.
RESUMO
BACKGROUND: To describe the effect of the COVID-19 pandemic on emergency general surgery operative volumes during governmental shutdowns secondary to the pandemic and characterize differences in disease severity, morbidity, and mortality during this time compared to previous years. METHODS: This retrospective cohort study compares patients who underwent emergency general surgery operations at a tertiary hospital from March 1st to May 31st of 2020 to 2019. Average emergent cases per day were analyzed, comparing identical date ranges between 2020 (pandemic group) and 2019 (control group). Secondary analysis was performed analyzing disease severity, morbidity, and mortality. RESULTS: From March 1st to May 31st, 2020, 2.5 emergency general surgery operations were performed on average daily compared to 3.0 operations on average daily in 2019, a significant decrease (P = .03). No significant difference was found in presenting disease severity, morbidity, or mortality between the pandemic and control groups. DISCUSSION: This study demonstrates a decrease of 65% in emergency general surgery operations during governmental restrictions secondary to the COVID-19 pandemic. This decrease in operations was not associated with worse disease severity, morbidity, or mortality.

ABSTRACT: Low- and middle-income countries (LMICs) have adopted procedural skill simulation, with researchers increasingly investigating simulation efforts in resource-strained settings. We aim to summarize the current state of procedural skill simulation research in LMICs focusing on methodology, clinical area, types of outcomes and cost, cost-effectiveness, and overall sustainability. We performed a comprehensive literature review of original articles that assessed procedural skill simulation from database inception until April 2022.From 5371 screened articles, 262 were included in this review. All included studies were in English. Most studies were observational cohort studies (72.9%) and focused on obstetrics and neonatal medicine (32.4%). Most measured outcome was the process of task performance (56.5%). Several studies mentioned cost (38.9%) or sustainability (29.8%). However, few articles included actual monetary cost information (11.1%); only 1 article assessed cost-effectiveness. Based on our review, future research of procedural skill simulation in LMICS should focus on more rigorous research, cost assessments, and on less studied areas.
RESUMO
The amount of waste heat generated annually in the UK exceeds the total annual electricity demand. Hence, it is crucial to effectively harness all available sources of waste heat based on their varying temperatures. Through suitable technologies, a substantial portion of this waste heat has the potential to be recovered for reutilization. Thermochemical energy storage (TCES) provides the best opportunities to recover waste heat at various temperatures for long-term storage and application. The potential of TCES with magnesium hydroxide, Mg(OH)2, has been established, but it has a relatively high dehydration temperature, thus limiting its potential for medium-temperature heat storage applications, which account for a vast proportion of industrial waste heat. To this end, samples of doped Mg(OH)2 with varying proportions (5, 10, 15, and 20 wt%) of potassium nitrate (KNO3) have been developed and characterized for evaluation. The results showed that the Mg(OH)2 sample with 5 wt% KNO3 achieved the best outcome and was able to lower the dehydration temperature of the pure Mg(OH)2 from about 317 °C to 293 °C with an increase in the energy storage capacity from 1246 J/g to 1317 J/g. It also showed a monodisperse surface topology and thermal stability in the non-isothermal test conducted on the sample and therefore appears to have the potential for medium heat storage applications ranging from 293 °C to 400 °C.
RESUMO
BACKGROUND: Although it seems natural that surgical trainees would learn from demonstrations of a correct performance, evidence outside of surgical education has suggested that error-focused examples may promote error detection and improved procedural task performance. We hypothesized that feedback through error-focused videos would improve procedural learning more than correct-focused videos. METHODS: We conducted a randomized controlled trial of video feedback comparing error-focused versus correct-focused examples. The participants were interviewees at our general surgery residency program in December 2020. All of the interviewees performed suturing and knot tying tasks on their interview day (baseline), with 70 common errors identified. For each error, we created an instructional feedback video in two formats: one video demonstrating the error and another demonstrating correct performance. The study participants received feedback videos based on baseline performance errors, with the format randomly assigned. Two blinded raters assessed the baseline and postintervention performances. RESULTS: Thirty-seven interviewees enrolled and 17 submitted postintervention videos. The postintervention mean performance scores were significantly higher (P = .02) in the error-focused than the correct-focused example group (suturing [maximum score 18]: 16.9 vs 13.9 [difference 2.9; 95% CI 0.7, 5.1]; knot-tying [maximum score 24]: 21.6 vs 17.8 [difference 3.8; 95% CI 0.5, 7.0]). We found no between-group differences in performance time ([error-focused versus correct-focused] suturing: 246 vs 256 s; knot-tying: 170 vs 138 s; P = .08). Mean satisfaction with feedback was similar between groups (error-focused: mean = 5.3 versus correct-focused: mean = 5.2, out of 7; P = .95). CONCLUSION: Feedback that highlights errors is associated with better learning of surgical skills than feedback demonstrating correct performance, confirming our hypothesis.

OBJECTIVE: In 2022, United States Medical Licensing Examination (USMLE) Step 1 scores will become pass/fail. This may be problematic, as residency programs heavily rely on USMLE Step 1 scores as a metric when determining interview invitations. This study aimed to assess candidate application metrics associated with USMLE Step 1 scores to offer programs new cues for stratifying applicants. DESIGN: Retrospective cohort study analyzing interviewed applicants to one general surgery residency program in 2019 and 2020. Applicant data analyzed included USMLE Step 1 scores, number of publications, clerkship scores, letter of recommendation scores (out of 2, scored by 0.25 interval), interview overall score (out of 5, scored by integer level), and standardized question score (out of 10). Each year, applicant's answers to one standardized behavioral question during their interview were scored by interviewers. SETTING: Tertiary medical center, academic general surgery residency program. PARTICIPANTS: Interviewed applicants at one general surgery residency program whose applications contained complete demographic information (203 out of 247). RESULTS: Multiple Linear Regression revealed that higher surgical clerkship (ßâ¯=â¯0.19, pâ¯=â¯0.006) and higher standardized interview question (ßâ¯=â¯0.32, p < 0.001) scores were positively associated with applicant USMLE Step 1 score (F[7, 195]â¯=â¯6.61, p < 0.001, R2â¯=â¯0.19). Letter of recommendation score, number of peer reviewed publications, gender, race, and applicant type (preliminary/categorical) were not associated with USMLE Step 1 scores. CONCLUSIONS: With USMLE Step 1 scores transitioning to pass/fail, surgical residency programs need new selection heuristics. Surgery clerkship scores and standardized behavioral questions answered by applicants prior to the interview could provide a holistic view of applicants and help programs better stratify candidates without USMLE Step 1 scores.

Purpose: Effective communication skills are a critical quality and skill that is highly sought after for surgeons which largely impacts patient outcomes. Residency programs design their interview processes to select the best candidates. LEGO®-based activities have been frequently used to enhance communication skills and team building. This study investigates the effectiveness and reliability of a novel LEGO®-based communication assessment in interviews for surgical residencies and the feasibility of implementing it in a virtual setting. Methods: This study conducted a retrospective analysis of a LEGO®-based communication assessment at the program's 2020/2021 residency interviews. Each applicant was assessed on a different model. The total scores were analyzed for consistency among raters and correlated to faculty interviews. Furthermore, the impact of the assessment structure, scoring criteria, and range of models' difficulties on the total scores were explored. Results: A total of 54 categorical and 55 preliminary applicants interviewed on 2 days. The assessment on different models and had no impact on applicants' total scores for either categorical and preliminary groups (p = 0.791 and 0.709, respectively). The communication components of the assessment showed high consistency between the raters. The two applicant groups displayed a statistically significant difference (p = 0.004) in the communication evaluation and model accuracy components. Total scores did not correlate with the faculty interviews of standardized questions in either group. Conclusion: This novel LEGO®-based communication assessment showed high reliability and promising results as a tool to assess communication and problem solving for residency interviews that can be readily implemented in a virtual setting.

RESUMO
OBJECTIVE: The main consideration during residency recruitment is identifying applicants who will succeed during residency. However, few studies have identified applicant characteristics that are associated with competency development during residency, such as the Accreditation Council for Graduate Medical Education milestones. As mini multiple interviews (MMIs) can be used to assess various competencies, we aimed to determine if simulated surgical skills MMI scores during a general surgery residency interview were associated with Accreditation Council for Graduate Medical Education milestone ratings at the conclusion of intern year. DESIGN: Retrospective cohort study. Interns' Step 1 and 2 clinical knowledge (CK) scores, interview day simulated surgical skills MMI overall score, traditional faculty interview scores, average overall milestone ratings in the spring of residency, and intern American Board of Surgery In-Training Examination (ABSITE) percentile scores were gathered. Two multiple linear regression were performed analyzing the association between Step 1, Step 2 CK, MMI, and traditional faculty interview scores with (1) average overall milestone rating and (2) ABSITE percentile scores, controlling for categorical/preliminary intern classification. SETTING: One academic medical center PARTICIPANTS: General surgery interns matriculating in 2020-2021 RESULTS: Nineteen interns were included. Multiple linear regression revealed that higher overall simulated surgical skills MMI score was associated with higher average milestone ratings (ßâ¯=â¯.45, pâ¯=â¯0.03) and higher ABSITE score (ßâ¯=â¯.43, pâ¯=â¯0.02) while neither Step 1, Step 2 CK, nor faculty interview scores were significantly associated with average milestone ratings. CONCLUSIONS: Surgical residency programs invest a tremendous amount of effort into training residents, thus metrics for predicting applicants that will succeed are needed. Higher scores on a simulated surgical skills MMIs are associated with higher milestone ratings 1 year into residency and higher intern ABSITE percentiles. These results indicate a noteworthy method, simulated surgical skills MMIs, as an additional metric that may select residents that will have early success in residency.
