Piloting a National Curricular Resource for the Transition to Surgical Residency: Characteristics of Participating Schools and Their Students.

OBJECTIVE: To determine the extent to which U.S. Liaison Committee of Medical Education (LCME)-accredited medical schools chose to participate in piloting a national curricular resource, the American College of Surgeons/Association of Program Directors in Surgery/Association of Surgical Education Resident Prep Curriculum ("ACS-surgery-prep curriculum"), and implications of such participation for student access nationally to this resource. DESIGN: We examined the significance of school-level differences in ACS-surgery-prep curriculum pilot participation and student-level differences in curriculum access based on medical school attended in bivariate analysis. SETTING: U.S. medical schools choosing to participate in the ACS-surgery-prep curriculum through 2021. Students graduating from U.S. LCME-accredited medical schools in 2020-2021 were invited to complete the Association of American Medical Colleges 2021 Graduation Questionnaire (GQ). PARTICIPANTS: Our study included data for 2569 students intending surgery specialties (16% of 16,353 2021 GQ respondents) from ACS-surgery-prep curriculum pilot and non-pilot schools. RESULTS: Of 148 medical schools attended by 2021 GQ respondents, 93 (63%) were identified as ACS-surgery-prep curriculum pilot schools. Pilot participation varied by school region, community-based designation, and research intensity (each p < 0.05) but not by ownership or transition to residency (TTR) course requirements (each p > 0.05). Of 2569 GQ respondents nationally intending surgery specialties, 1697 (66%) attended an ACS-surgery-prep curriculum pilot school; this proportion did not vary by gender or race/ethnicity (each p > 0.05) but varied by students' school TTR course requirements (p < 0.001). Findings were similar among the 1059 students intending general surgery specialties specifically (41% of all 2569 students intending surgery specialties). CONCLUSIONS: Many U.S. LCME-accredited medical schools piloted this national TTR surgery curriculum. School-level characteristics associated with pilot participation can inform outreach efforts to encourage the participation of interested schools in piloting this TTR resource. With this curriculum distribution model, we observed no gender or racial/ethnic disparities in curriculum access nationally among students intending surgery specialties.

Utilizing Simulation to Evaluate Robotic Skill Acquisition and Learning Decay.

BACKGROUND: We aim to evaluate how new robotic skills are acquired and retained by having participants train and retest using exercises on the robotic platform. We hypothesized that participants with a 3-month break from the robotic platform will have less learning decay and increased retention compared with those with a 6-month break. METHODS: This was a prospective randomized trial in which participants voluntarily enrolled and completed an initial training phase to reach proficiency in 9 robot simulator exercises. They were then instructed to refrain from practicing until they retested either 3 or 6 months later. This study was completed at an academic medical center within the general surgery department. Participants were medical students, and junior-level residents with minimal experience in robotic surgery were enrolled. A total of 27 enrolled, and 13 participants completed the study due to attrition. RESULTS: Overall, intragroup analysis revealed that participants performed better in their retest phase compared with their initial training in terms of attempts to reach proficiency, time for completion, penalty score, and overall score. Specifically, during the first attempt in the retesting phase, the 3-month group did not deviate far from their final attempt in the training phase, whereas the 6-month group experienced significantly worse time to complete and overall score in interrupted suturing {[-4 (-18 to 20) seconds vs. 109 (55 to 118) seconds, P =0.02] [-1.3 (-8 to 1.9) vs. -18.9 (-19.5 to (-15.0)], P =0.04} and 3-arm relay {[3 (-4 to 23) seconds vs. 43 (30 to 50) seconds, P =0.02] [0.4 (-4.6 to 3.1) vs. -24.8 (-30.6 to (-20.3)], P =0.01] exercises. In addition, the 6-month group had a significant increase in penalty score in retesting compared with the 3-month group, which performed similarly to their training phase [3.3 (2.7 to 3.3) vs. 0 (-0.8 to 1.7), P =0.03]. CONCLUSIONS: This study identified statistically significant differences in learning decay, skills retention, and proficiency between 3-month and 6-month retesting intervals on a robotic simulation platform.

HIV-1 DNA and Immune Activation Levels Differ for Long-Lived T-Cells in Lymph Nodes, Compared with Peripheral Blood, during Antiretroviral Therapy.

Elucidating the mechanisms underlying the persistence and location of the HIV reservoir is critical for developing cure interventions. While it has been shown that levels of T-cell activation and the size of the HIV reservoir are greater in rectal tissue and lymph nodes (LN) than in blood, the relative contributions of T-cell subsets to this anatomic difference are unknown. We measured and compared HIV-1 DNA content, expression of the T-cell activation markers CD38 and HLA-DR, and expression of the exhaustion markers programmed cell death protein 1 (PD-1) and T-cell immunoreceptor with immunoglobulin and immunoreceptor tyrosine-based inhibitory motif domains (TIGIT) in naive, central memory (CM), transitional memory (TM), and effector memory (EM) CD4+ and CD8+ T-cells in paired blood and LN samples among 14 people with HIV who were receiving antiretroviral therapy. HIV-1 DNA levels, T-cell immune activation, and TIGIT expression were higher in LN than in blood, especially in CM and TM CD4+ T-cell subsets. Immune activation was significantly higher in all CD8+ T-cell subsets, and memory CD8+ T-cell subsets from LN had higher levels of PD-1 expression, compared with blood, while TIGIT expression levels were significantly lower in TM CD8+ T-cells. The differences seen in CM and TM CD4+ T-cell subsets were more pronounced among participants with CD4+ T-cell counts of <500 cells/µL within 2 years after antiretroviral therapy initiation, thus highlighting increased residual dysregulation in LN as a distinguishing feature of and a potential mechanism for individuals with suboptimal CD4+ T-cell recovery during antiretroviral therapy. IMPORTANCE This study provides new insights into the contributions of different CD4+ and CD8+ T-cell subsets to the anatomic differences between LN and blood in individuals with HIV who have optimal versus suboptimal CD4+ T-cell recovery. To our knowledge, this is the first study comparing paired LN and blood CD4+ and CD8+ T-cell differentiation subsets, as well as those subsets in immunological responders versus immunological suboptimal responders.

Oncologic Outcomes of Multi-Institutional Minimally Invasive Inguinal Lymph Node Dissection for Melanoma Compared with Open Inguinal Dissection in the Second Multicenter Selective Lymphadenectomy Trial (MSLT-II).

BACKGROUND: Minimally invasive inguinal lymphadenectomy (MILND) is safe and feasible, but limited data exist regarding oncologic outcomes. METHODS: This study performed a multi-institutional retrospective cohort analysis of consecutive MILND performed for melanoma between January 2009 and June 2016. The open ILND (OILND) comparative cohort comprised patients enrolled in the second Multicenter Selective Lymphadenectomy Trial (MSLT-II) between December 2004 and March 2014.The pre-defined primary end point was the same-basin regional nodal recurrence, calculated using properties of binomial distribution. Time to events was calculated using the Kaplan-Meier method. The secondary end points were overall survival, progression-free survival, melanoma-specific survival (MSS), and distant metastasis-free survival (DMFS). RESULTS: For all the patients undergoing MILND, the same-basin regional recurrence rate was 4.4 % (10/228; 95 % confidence interval [CI], 2.1-7.9 %): 8.2 % (4/49) for clinical nodal disease and 3.4 % (6/179) for patients with a positive sentinel lymph node (SLN) as the indication. For the 288 patients enrolled in MSLT-II who underwent OILND for a positive SLN, 17 (5.9 %) had regional node recurrence as their first event. After controlling for ulceration, positive LN count and positive non-SLNs at the time of lymphadenectomy, no difference in OS, PFS, MSS or DMFS was observed for patients with a positive SLN who underwent MILND versus OILND. CONCLUSION: This large multi-institutional experience supports the oncologic safety of MILND for melanoma. The outcomes in this large multi-institutional experience of MILND compared favorably with those for an OILND population during similar periods, supporting the oncologic safety of MILND for melanoma.

How We Do It: Remediation Pathways in a Surgical Simulation Curriculum for Competency Improvement.

OBJECTIVE: Validated assessment of procedural knowledge and skills with formative remediation is a foundational part of achieving surgical competency. High-fidelity simulation programs provide a unique area to assess resident proficiency and independence, as well as to assist in identifying residents in need of further practice. While several studies have validated the use of simulation to attain proficiency of specific technical skills, few have validated remediation pathways for their trainees objectively. In this descriptive analysis, we review 2 remediation pathways within our simulation training curricula and how these are used in assessments of resident proficiency. MATERIALS AND METHODS: Two methods of remediation were formulated for use in high-fidelity simulation labs. One remediation pathway was a summative process, where ultimate judgment of resident competency was assessed through intra-operative assessments of a holistic skill set. The second remediation pathway was a formative "coaching" process, where feedback is given at several intervals along the pathway towards a specific technical skills competence. All general surgery residents are enrolled in the longitudinal, simulation curricula. RESULTS: Approximately one-third of surgical residents entered into a remediation pathway for either of the high-fidelity simulation curricula. Both residents and faculty expressed support for the summative and formative remediation pathways as constructed. Residents who entered remediation pathways believed it was a beneficial exercise, and the most common feedback was that remediation principles should be expanded to all residents. Interestingly, faculty demonstrated stronger support for the formative coaching feedback model than the summative assessment model. CONCLUSIONS: Through the complementary use of both formative and summative remediation pathways, resident competence can be enriched in a constructive, nonpunitive method for self-directed performance improvement. Both trainees and faculty express high satisfaction with programs explicitly organized to ensure that skills are rated through a standardized process.

Do Oncologic Outcomes From Head and Neck Versus Truncal and Extremity Melanoma Differ? A Single-Institution Single-Subspecialty Experience.

BACKGROUND: Outcomes are thought to be worse in head and neck (H&N) melanoma patients. However, definitive evidence of inferior outcomes in H&N melanoma in the modern era is lacking. We sought to ascertain whether H&N melanomas carry a worse prognosis than melanomas of other sites. METHODS: All patients who underwent excision for primary melanoma by fellowship-trained surgical oncologists at a single institution from 2014 to 2020 were queried from the electronic medical record. Patients who had AJCC eighth edition stage I-III disease were included. RESULTS: Of 1127 patients, 28.7% had primary H&N melanoma. H&N patients were more likely to be male, older, and present with more advanced AJCC stage. Median follow-up was 20.0 months (IQR 26.4). On multivariable analyses controlling for other variables, H&N melanoma was associated with worse RFS. Notably, H&N melanoma was not associated with worse MSS, DMFS, or OS on univariate or multivariable analyses. Among patients who recurred, H&N patients were significantly more likely to recur locally compared to non-H&N patients. On subgroup analysis, scalp melanoma was also associated with worse RFS compared to patients with melanoma in locations other than the scalp. When patients with scalp melanoma were excluded from analysis, non-scalp H&N RFS was not significantly different from the non-H&N group on univariate or multivariable analyses. DISCUSSION: In this series from a high-volume tertiary referral center, the differences in rates and sites of recurrence between H&N and non-H&N melanoma do not impact melanoma-specific or overall survival, suggesting that H&N melanoma patients should be treated similarly with respect to regional and systemic therapies.

Talimogene Laherparepvec (T-VEC) for the Treatment of Advanced Locoregional Melanoma After Failure of Immunotherapy: An International Multi-Institutional Experience.

BACKGROUND: Talimogene laherparepvec (T-VEC) is an oncolytic virus approved for the treatment of unresectable, recurrent melanoma. The role of T-VEC after progression on systemic immunotherapy (IO) remains undefined. The goal of this study was to characterize the efficacy of T-VEC after failure of IO in patients with unresectable metastatic melanoma. METHODS: An international, multi-institutional review of AJCC version 8 stage IIIB-IV melanoma patients treated with T-VEC after failure of IO was performed at six centers from October 2015-December 2020. Primary outcome was in-field response; secondary outcomes included analyses of in-field and overall progression-free survival (PFS) and in-field and overall disease-free survival (DFS) after a complete response. Subset analysis of T-VEC initiation sequentially after or concurrently with IO was performed. RESULTS: Of 112 patients, median age at T-VEC initiation was 69 years (range 21-93); 65 (58%) were male. Before T-VEC, 57% patients received one IO regimen, 42% received two or more, with most patients (n = 74, 66%) receiving T-VEC sequential to IO. Most were stage 3C (n = 51, 46%) at T-VEC initiation, 29 (26%) received injections to nodal disease. Over median follow-up of 14 months, in-field response at final T-VEC injection was 37% complete (CR), 14% partial (PR). T-VEC initiation sequentially or concurrently did not significantly affect in-field response (p = 0.26). Median in-field PFS was 15 months (95% confidence interval 4.6-NE). Median overall DFS after CR was 32 months (95% confidence interval 17-NE). CONCLUSIONS: T-VEC after failure of IO is effective in unresectable, metastatic stage IIIB-IV melanoma. T-VEC initiation sequentially or concurrently did not significantly affect in-field response.

Clinical Case-Conference Blogs: Integrating Clinical Librarians to Enhance Resident Education and Enforce ACGME Competencies.

Resident conferences are primary educational endeavors for trainees and faculty alike. We describe the development of collaborative clinician-librarian educational blogs within the Internal Medicine (2009), Pediatrics (2012), and General Surgery (2018) residency programs. Clinical librarians attended resident conferences and generated evidence-based blog posts based on learning topics and clinical questions encountered during the conferences. In the decade since introduction of the blogs, this partnership has resulted in over 2000 blog posts and generated over 1800 individual views per month. The development of a clinical librarian-managed blog serves as a relevant resource for promoting evidence-based practices within a case-based learning curriculum, engages interdisciplinary collaboration through existing resources, and is generalizable across various clinical practice disciplines and trainees.

Increased homeostatic cytokines and stability of HIV-infected memory CD4 T-cells identify individuals with suboptimal CD4 T-cell recovery on-ART.

Clinical outcomes are inferior for individuals with HIV having suboptimal CD4 T-cell recovery during antiretroviral therapy (ART). We investigated if the levels of infection and the response to homeostatic cytokines of CD4 T-cell subsets contributed to divergent CD4 T-cell recovery and HIV reservoir during ART by studying virologically-suppressed immunologic responders (IR, achieving a CD4 cell count >500 cells/µL on or before two years after ART initiation), and virologically-suppressed suboptimal responders (ISR, did not achieve a CD4 cell count >500 cells/µL in the first two years after ART initiation). Compared to IR, ISR demonstrated higher levels of HIV-DNA in naïve, central (CM), transitional (TM), and effector (EM) memory CD4 T-cells in blood, both pre- and on-ART, and specifically in CM CD4 T-cells in LN on-ART. Furthermore, ISR had higher pre-ART plasma levels of IL-7 and IL-15, cytokines regulating T-cell homeostasis. Notably, pre-ART PD-1 and TIGIT expression levels were higher in blood CM and TM CD4 T-cells for ISR; this was associated with a significantly lower fold-changes in HIV-DNA levels between pre- and on-ART time points exclusively on CM and TM T-cell subsets, but not naïve or EM T-cells. Finally, the frequency of CM CD4 T-cells expressing PD-1 or TIGIT pre-ART as well as plasma levels of IL-7 and IL-15 predicted HIV-DNA content on-ART. Our results establish the association between infection, T-cell homeostasis, and expression of PD-1 and TIGIT in long-lived CD4 T-cell subsets prior to ART with CD4 T-cell recovery and HIV persistence on-ART.

Trainee Utilization of the SCORE Curriculum is Associated With Improved ABSITE Performance: A Multi-institutional Study.

BACKGROUND: The Surgical Council on Resident Education's (SCORE) structured educational curriculum for general surgery residents uses a 2-year repeating cycle of modules and quizzes called "This Week in SCORE" (TWIS) to organize and sequence the curricular content on the SCORE portal. The purpose of this study was to evaluate the impact of using the SCORE content and TWIS curriculum on American Board of Surgery In-Training Examination (ABSITE) performance. To date, no multi-institutional studies have examined this effect. METHODS: Eight residency programs participated, including university and community-based programs. SCORE usage overall, TWIS usage, and ABSITE percentile scores (adjusted for post-graduate year [PGY]) were analyzed for the academic years 2017 to 2020. SCORE usage was defined as number of SCORE logins annually per resident with "low usage" ≤10 times and "high usage" >10 times. TWIS usage was defined as "low usage" (no TWIS quizzes done) or "high usage" (≥1 TWIS quiz per year). RESULTS: Four hundred and twenty-eight trainees were evaluated. Trainees with high SCORE and TWIS usage consistently achieved a higher ABSITE percentile score. This difference was maintained in subgroup analysis by PGY with the greatest impact in PGY-1 and PGY-2 levels. CONCLUSIONS: Utilization of multiple aspects of SCORE content appears to have a significant positive impact on ABSITE performance across all levels of postgraduate training. This multi-institutional study of a large number of users is the first to demonstrate that increased usage of SCORE content appears to be a predictor of ABSITE performance success.

Relationship between burnout and mistreatment: Who plays a role?

INTRODUCTION: Surgery residents have high burnout rates and mistreatment occurs during training. We hypothesized that residents who reported mistreatment would be more likely to experience burnout. METHODS: A multi-institutional observational study asked residents to complete the Maslach Burnout Inventory and to rate how often they experienced mistreatment. Scores in the high-risk range for emotional exhaustion or depersonalization were classified as burnout. Associations between mistreatment behaviors, program, sex, post graduate year(PGY), and clinical status were measured by Spearman's correlation, linear regression, and logistic regression. RESULTS: We invited 398 residents to participate; 180 responded(45%). 52%(n = 93) were female, there was an even distribution among PGY, and seven programs were represented. Almost half of the cohort (48%) reported high risk for burnout and 68% reported experiencing mistreatment. Mistreatment by senior physician team members were correlated with EE(rho = 0.184,p = 0.016) and DP(rho = 0.181,p = 0.016). CONCLUSION: While overall burnout was not significantly associated with mistreatment behaviors, both burnout and mistreatment were commonly reported.

Non-technical skill assessments across levels of US surgical training.

BACKGROUND: To ensure safe patient care, regulatory bodies worldwide have incorporated non-technical skills proficiency in core competencies for graduation from surgical residency. We describe normative data on non-technical skill ratings of surgical residents across training levels using the US-adapted Non-Technical Skills for Surgeons (NOTSS-US) assessment tool. METHODS: We undertook an exploratory, prospective cohort study of 32 residents-interns (postgraduate year 1), junior residents (postgraduate years 2-3), and senior residents (postgraduate years 4-5)-across 3 US academic surgery residency programs. Faculty went through online training to rate residents, directly observed residents while operating together, then submitted NOTSS-US ratings on specific resident's intraoperative performance. Mean NOTSS-US ratings (total range 4-20, sum of category scores; situation awareness, decision-making, communication/teamwork, leadership each ranged 1-5, with 1=poor, 3=average, 5=excellent) were stratified by residents' training level and adjusted for resident-, rater-, and case-level variables, using mixed-effects linear regression. RESULTS: For 80 operations, the overall mean total NOTSS-US rating was 12.9 (standard deviation, 3.5). The adjusted mean total NOTSS-US rating was 16.0 for senior residents, 11.6 for junior residents, and 9.5 for interns. Adjusted differences for total NOTSS-US ratings were statistically significant across the following training levels: senior residents to interns (6.5; 95% confidence interval, 4.3-8.7; P < .001), senior to junior residents (4.4; 95% confidence interval, 2.5-6.2; P < .001), and junior residents to interns (2.1; 95% confidence interval, 0.3-3.9; P = .017). Differences in adjusted NOTSS-US ratings across residents' training levels persisted for individual NOTSS-US behavior categories. CONCLUSION: These data and online training materials can support US residency programs in determining competency-based performance milestones to develop surgical trainees' non-technical skills.

The Impact of Obesity on Surgically Treated Locoregional Melanoma.

BACKGROUND: The impact of obesity on early-stage melanoma is poorly understood. We examined the impact of overweight and obesity on clinical outcomes in locoregional melanoma. METHODS: Adults who underwent surgery at Emory University Healthcare between 2010 and 2017 for clinically stage I-II cutaneous melanoma, with known stage, height, and weight at the time of presentation, were identified. The relationship between body mass index (BMI) and clinicopathologic characteristics was assessed. RESULTS: Of 1756 patients, 584 were obese (33.2%; BMI ≥ 30), 658 were overweight (37.5%; BMI ≥ 25 and < 30), and 514 were normal weight (29.3%; BMI < 25). Demographics associated with obesity included male sex (odds ratio [OR] 2.6, 95% confidence interval [CI] 2.1-3.3; p < 0.001) and lower income (OR 1.5, 95% CI 1.2-1.9; p = 0.003). Melanomas in obese patients were thicker (2.0 ± 0.2 mm) than in overweight (1.7 ± 0.1 mm) or normal-weight patients (1.4 ± 0.1 mm; p = 0.002). Ulceration, mitoses, BRAF status, and sentinel lymph node (SLN) status were not affected by obesity. In multivariable analysis, obesity independently predicted increased odds of pathologic stage II melanoma (vs. stage 0 or I; OR 1.9, 95% CI 1.4-2.7, p = 0.001), but not pathologic stage III melanoma (p > 0.05). At 33 months' median follow-up, obesity was not an independent predictor of stage-specific overall survival (p > 0.05). CONCLUSION: Obese patients are nearly twice as likely as their normal-weight peers to present with thicker melanomas, but they have similar stage-specific overall survival and SLN positivity. Obesity may promote more aggressive growth of the primary tumor, and barriers to preventive care in obese patients may exacerbate later-stage presentation.

A longitudinal cadaver-based simulation curriculum creates sustainable increases in resident confidence and exposure to fundamental techniques: Results of a 5-year program evaluation.

INTRODUCTION: For the past five years, our surgical residency program has led a cadaver-based simulation course focused on fundamental surgical maneuvers. This study aimed to quantify the impact of this course on resident exposure to surgical skills and longitudinal impact on resident education. METHODS: General surgery residents participated in an annual cadaver-based simulation curriculum. Participants completed surveys regarding improvements in knowledge and confidence; these results were stratified between course iterations (P1: 2 years, 2014-15; P2: 3 years, 2016-2018). RESULTS: Residents reported a sustained increase in knowledge of anatomy and technical dissection, confidence in performing operative skills independently, and exposure to operative skills that were otherwise not encountered in clinical rotations. Junior residents demonstrated an increase in gaining skills they would otherwise not achieve (87% vs. 98%, p = 0.028) and confidence to safely perform these procedures in the clinical setting (94% vs. 100%, p = 0.077). CONCLUSION: This annual, longitudinal cadaver-based skills course focused on fundamental maneuvers demonstrates a sustained impact in resident and faculty surgical confidence in resident's operative skills as a component of a longitudinal simulation curriculum to enhance competency-based promotion.

APDS Consensus Statement: Ideal Senior Medical Student Experiences for Preparedness for General Surgery Internship.

OBJECTIVE: Guide optimal standards on ideal senior medical student experiences for preparedness for general surgery internship DESIGN: Work product of task force, approved by the Association of Program Directors in Surgery CONCLUSION: General surgery rotations should mirror the learning and working environment of a surgical intern. Opportunities should mimic the next phase of learning to help guide informed decisions regarding entrustability for entry into residency training. These opportunities will also help identify students who may have an aptitude for pursuing a general surgery internship. Students should achieve entrustability in Association of American Medical Colleges Core Entrustable Professional Activities (EPAs); curricula should align Core EPAs and modified American Board of Surgery EPAs to guide essential general surgery components. Experiences should include required night, holiday, and/or weekend shifts, a dedicated critical care experience, and a resident preparatory curriculum focusing on nontechnical and essential technical skills. We encourage the opportunity for additional surgical mentorship and subspecialty experience through Surgical Interest Groups or Surgical Honors or Specialty Tracks.
