RESUMEN

IMPORTANCE: It is uncertain whether current measures of achievement during medical school predict exceptional performance during surgical residency. One surrogate of excellence during residency may be awards, especially those given for teaching and annual overall accomplishment. OBJECTIVE: Determine whether markers of superior performance during medical school documented in the Electronic Residency Application Service (ERAS) application and student record correlated with receiving awards during residency. DESIGN: Data was analyzed from ERAS and student applications of 296 residency graduates. Spearman correlation coefficients were calculated. PARTICIPANTS: 296 residency graduates from 14 US general surgery residency programs. MAIN OUTCOMES AND MEASUREMENTS: The relationship between each residency and preresidency variable and the outcome of receiving any qualifying award. Secondary analysis included the correlation with winning a teaching or annual overall award. RESULTS: Although 140 (48%) residents received an award during residency, only 69 (23.3%) received a teaching award, while 50 (17.6%) received one for annual overall performance. Membership in Alpha Omega Alpha (AOA) and honors in pediatrics rotation correlated with receiving any award. USMLE step 1 score and AOA membership reached statistically significant positively correlation with receiving a teaching award, while completing a sub-internship at that institution was negatively associated. For annual overall awards, only completing a sub-internship at the same institution reached statistical significance. CONCLUSIONS: None of the traditional metrics in the ERAS or global student record consistently correlated with receiving an award during residency. Our findings suggest that preresidency factors available on the global application, including grades, test scores, and honor society membership, poorly correlate with exceptional general surgery residency performance as measured by receiving awards. Residency programs should shift away from using traditional ERAS metrics as the primary criteria for selection, but rather as 1 component of holistic applicant review.

RESUMEN

BACKGROUND: Nipple delay (ND) is a staged procedure that improves nipple-areolar complex (NAC) viability in nipple-sparing mastectomy (NSM) patients who are high-risk for NAC or skin-flap necrosis. This study compared postoperative outcomes and risk factors between patients treated with ND-NSM and NSM alone. METHODS: Patient demographics, risk factors for NAC or skin-flap necrosis, tumor characteristics, and operative outcomes were compared between ND-NSM and NSM groups from 2009 to 2023. Univariate and multivariate analyses were performed to identify significant variables associated with NAC or skin-flap necrosis. RESULTS: Overall, 71 ND-NSM patients and 537 NSM patients were compared. ND-NSM patients had larger breasts (p < 0.01), body mass index ≥ 30 (p = 0.01), prior breast/chest wall radiation (XRT) [p < 0.01], prior breast operations (p < 0.01), less axillary surgery (p < 0.01), more autologous tissue reconstruction over implant-based reconstruction compared with NSM patients (p = 0.02), and more prophylaxis (p < 0.01). There were no statistically significant differences between groups in regard to infection, skin-flap necrosis, NAC necrosis, seromas, and hematomas. No patients in the ND-NSM group had NAC necrosis and 1 patient had skin-flap necrosis, compared with 17 and 13 patients in the NSM group, respectively (p = 0.24). On univariate analysis, prior XRT was associated with increased risk for skin-flap necrosis (p = 0.02). Multivariate analysis showed XRT was associated with skin-flap necrosis (p = 0.02) and any necrosis (p = 0.01). Breast size was associated with NAC or skin-flap necrosis (p = 0.04). CONCLUSION: Larger breasts and XRT were risk factors for NAC or skin-flap necrosis; however, despite having more risk factors, ND-NSM patients had very low rates of necrosis. Notably, no nipples were lost. A shared decision should be made with patients regarding the risks and benefits of ND-NSM.

RESUMEN

Importance: Because mentorship is critical for professional development and career advancement, it is essential to examine the status of mentorship and identify challenges that junior surgical faculty (assistant and associate professors) face obtaining effective mentorship. Objective: To evaluate the mentorship experience for junior surgical faculty and highlight areas for improvement. Design, Setting, and Participants: This qualitative study was an explanatory sequential mixed-methods study including an anonymous survey on mentorship followed by semistructured interviews to expand on survey findings. Junior surgical faculty from 18 US academic surgery programs were included in the anonymous survey and interviews. Survey responses between "formal" (assigned by the department) vs "informal" (sought out by the faculty) mentors and male vs female junior faculty were compared using χ2 tests. Interview responses were analyzed for themes until thematic saturation was achieved. Survey responses were collected from November 2022 to August 2023, and interviews conducted from July to December 2023. Exposure: Mentorship from formal and/or informal mentors. Main Outcomes and Measures: Survey gauged the availability and satisfaction with formal and informal mentorship; interviews assessed broad themes regarding mentorship. Results: Of 825 survey recipients, 333 (40.4%) responded; 155 (51.7%) were male and 134 (44.6%) female. Nearly all respondents (319 [95.8%]) agreed or strongly agreed that mentorship is important to their surgical career, especially for professional networking (309 respondents [92.8%]), career advancement (301 [90.4%]), and research (294 [88.3%]). However, only 58 respondents (18.3%) had a formal mentor. More female than male faculty had informal mentors (123 [91.8%] vs 123 [79.4%]; P = .003). Overall satisfaction was higher with informal mentorship than formal mentorship (221 [85.0%] vs 40 [69.0%]; P = .01). Most male and female faculty reported no preferences in gender or race and ethnicity for their mentors. When asked if they had good mentor options if they wanted to change mentors, 141 (47.8%) responded no. From the interviews (n = 20), 6 themes were identified, including absence of mentorship infrastructure, preferred mentor characteristics, and optimizing mentorship. Conclusions and Relevance: Academic junior surgical faculty agree mentorship is vital to their careers. However, this study found that few had formal mentors and almost half need more satisfactory options if they want to change mentors. Academic surgical programs should adopt a framework for facilitating mentorship and optimize mentor-mentee relationships through alignment of mentor-mentee goals and needs.

RESUMEN

BACKGROUND: Increased screening and treatment advancements have resulted in improved survival rates in women with breast cancer (BC). However, recent data suggests these women have elevated risk of developing a second primary malignancy (SPM) compared to the general population. Limited data exists on factors associated with BC patients developing a SPM. METHOD: A retrospective review of a prospective single institution database (1990-2016) identified 782 patients with a history of BC. One hundred and ninety-four BC patients developed a SPM. Clinicopathologic and treatment characteristics were analyzed. RESULTS: Of the 194 patients (24.8%) who developed a SPM, 56 (28.9%) BC patients were <50 years old (range: 24-87 years). Two-thirds (64.9%) had at least one first or second degree relative with a malignancy (no relatives-35.1%; ≥1 relative-62.9%). Most patients had invasive ductal carcinoma (n = 117, 60.3%) or ductal carcinoma in situ (n = 39, 20.1%). Twenty-two patients (11.3%) had pathogenic genetic mutations. Mean time to developing a SPM was 8.9 years (range: 4 months-50 years). Eighty (47.6%) patients received chemotherapy with 91 (54.5%) completing radiation. The most common SPMs were breast (22%), melanoma (17.8%), gynecologic (14.1%), colorectal (12.6%), hematologic (8.9%), and sarcoma (6.5%). Most breast tumors were estrogen receptor (ER) (n = 99, 78.0%) or progesterone receptor (PR) positive (n = 87, 73.1%) but not HER2-neu positive (n = 13, 14.0%). CONCLUSION: Most BC patients who developed a SPM had ER/PR positive tumors and a family history of malignancy, with most <50 years old. Although chemotherapy and radiation increase cancer risk, there were an equal number of patients with SPMs who did or did not receive either treatment. Most SPMs were breast, soft tissue, gynecologic, hematologic, or colorectal. BC patients should be followed closely given an elevated propensity for developing SPMs.

RESUMEN

Patients with gastroenteropancreatic (GEP) neuroendocrine tumors (NET) often present with advanced disease. Primary tumor resection (PTR) in the setting of unresectable metastatic disease is controversial. Most studies evaluating the impact of PTR on overall survival (OS) have been performed using large population-based databases, with limited treatment related data. This study aims to determine whether PTR improves OS and progression-free survival (PFS) in patients with metastatic well-differentiated GEP-NET. This is a retrospective single-institution study of patients with metastatic well-differentiated GEP-NET between 1978 and 2021. The primary outcome was OS. The secondary outcome was PFS. Chi-squared tests and Cox regression were used to perform univariate and multivariate analyses (MVA). OS and PFS were estimated using the Kaplan-Meier method and log-rank test. Between 1978 and 2021, 505 patients presented with metastatic NET, 151 of whom had well-differentiated GEP-NET. PTR was performed in 31 PNET and 77 SBNET patients. PTR was associated with improved median OS for PNET (136 vs. 61 months, p = .003) and SBNET (not reached vs. 79 months, p<.001). On MVA, only higher grade (HR 3.70, 95%CI 1.49-9.17) and PTR (HR 0.21, 95%CI 0.08-0.53) influenced OS. PTR resulted in longer median PFS for patients with SBNET (46 vs. 28 months, p = .03) and a trend toward longer median PFS for patients with PNET (20 vs. 13 months, p = .07). In patients with metastatic well-differentiated GEP-NET, PTR is associated with improved OS and may be associated with improved PFS and should be considered in a multidisciplinary setting. Future prospective studies are needed to validate these findings.

RESUMEN

BACKGROUND: Nipple sparing mastectomy (NSM) is increasingly being performed for patients with breast cancer. However, optimal postoperative surveillance has not been defined. METHODS: A prospectively maintained database identified patients with in-situ and invasive cancer who underwent NSM between 2007-2021. Clinical data on postoperative breast surveillance and interventions were collected. Patients who had MRI surveillance versus clinical breast exam (CBE) alone were compared with respect to tumor characteristics, recurrence, and survival. RESULTS: A total of 483 NSMs were performed on 399 patients. 255 (63.9%) patients had invasive ductal carcinoma, 31 (7.8%) invasive lobular carcinoma, 92 (23.1%) DCIS, 6 (1.5%) mixed ductal and lobular carcinoma, 9 (2.3%) others, and 6 (1.5%) unknown. Postoperatively, 265 (66.4%) patients were followed with CBE alone and 134 (33.6%) had surveillance MRIs. At a median follow-up of 33 months, 20 patients (5.0%) developed in-breast recurrence, 6 patients had (1.5%) an axillary recurrence, and 28 with (7.0%) distant recurrence. 14 (53.8%) LRR were detected in the CBE group and 12 (46.2%) were detected in the MRI group (P = .16). Overall survival (OS) was 99%, with no difference in OS between patients who had CBE alone versus MRI (P = .46). MRI was associated with higher biopsy rates compared to CBE alone (15.8% vs. 7.8%, P = .01). CONCLUSIONS: Compared to CBE alone, the use of screening MRI following NSM results in higher rate of biopsy and no difference in overall survival.

RESUMEN

OBJECTIVE: To determine whether participation in certain hobbies (e.g., participation in sports, playing musical instruments, or other hobbies requiring fine motor skills), preresidency, are associated with higher technical skills ratings at the time of residency graduation. DESIGN: Faculty members from 14 general surgery residency programs scored individual graduates from 2017 to 2020 on their technical skills using a 5-point Likert scale. Hobbies for these residents were collected from their Electronic Residency Application Service (ERAS) data. A single reviewer classified each ERAS hobby into predefined categories including musical instruments, sports requiring hand-eye coordination, team sports, and activities necessitating hand-eye coordination. Spearman correlation coefficients were calculated for the relationship between each category of hobby-as well as the total number of hobbies in each category-and the outcome of surgical faculty ratings of residents' technical surgical skills during their last year of residency. A proportional odds model including the above predictive variables was also fit to the data. SETTING: Fourteen general surgery residency programs. PARTICIPANTS: General surgery residency graduates from 14 different programs from 2017 to 2020. RESULTS: There were 296 residents across 14 institutions. The average ranking of residents' technical skills was 3.24 (SD 1.1). A total of 40% of residents played sports involving hand-eye coordination, 31% played team sports, 28% participated in nonsport hobbies that require eye-hand coordination, and 20% played musical instruments. Correlation coefficients were not statistically significant for any of the categories. In the proportional odds model, none of the variables were associated with statistically significant increased odds of a higher technical skills rating. CONCLUSIONS: There was no correlation between general surgery chief residents' technical skills as rated by faculty, and self-reported pre-residency hobbies on the ERAS application. These findings suggest such hobbies prior to residency are unlikely to predict future technical skills prowess.

RESUMEN

BACKGROUND: National guidelines recommend omitting SNB in older patients with favorable invasive breast cancer. However, there is a lack of prospective data specifically addressing this issue. This study evaluates recurrence and survival in estrogen receptor-positive/Her2- (ER+) breast cancer patients, aged ≥ 65 years who have breast-conserving surgery (BCS) without SNB. METHODS: This is a prospective, observational study at a single institution where 125 patients aged ≥ 65 years with clinical T1-2N0 ER+ invasive breast cancer undergoing BCS were enrolled. Patients were treated with BCS without SNB. Primary outcome measure was axillary recurrence. Secondary outcome measures include recurrence-free survival (RFS), disease-free survival (DFS), breast cancer-specific survival (BCSS), and overall survival (OS). RESULTS: From January 2016 to July 2022, 125 patients were enrolled with median follow-up of 36.7 months [95% confidence interval (CI) 35.0-38.0]. Median age was 77.0 years (range 65-93). Median tumor size was 1 cm (range 0.1-5.0). Most tumors were ductal (95/124, 77.0%), intermediate grade (60/116, 51.7%), and PR-positive (117/123, 91.7%). Radiation therapy was performed in 37 of 125 (29.6%). Only 60 of 125 (48.0%) who were recommended hormonal therapy were compliant at 2 years. Chemotherapy was administered to six of 125 (4.8%) patients. There were two of 125 (1.6%) axillary recurrences. Estimated 3-years rates of regional RFS, DFS, and OS were 98.2%, 91.2%, and 94.8%, respectively. Univariate Cox regression identified hormonal therapy noncompliance to be significantly associated with recurrence (p = 0.02). CONCLUSIONS: Axillary recurrence rates were extremely low in this cohort. These results provide prospective data to support omission of SNB in this patient population TRIAL REGISTRATION: ClinicalTrials.gov ID NCT02564848.

RESUMEN

Strategies are needed to better identify patients that will benefit from immunotherapy alone or who may require additional therapies like chemotherapy or radiotherapy to overcome resistance. Here we employ single-cell transcriptomics and spatial proteomics to profile triple negative breast cancer biopsies taken at baseline, after one cycle of pembrolizumab, and after a second cycle of pembrolizumab given with radiotherapy. Non-responders lack immune infiltrate before and after therapy and exhibit minimal therapy-induced immune changes. Responding tumors form two groups that are distinguishable by a classifier prior to therapy, with one showing high major histocompatibility complex expression, evidence of tertiary lymphoid structures, and displaying anti-tumor immunity before treatment. The other responder group resembles non-responders at baseline and mounts a maximal immune response, characterized by cytotoxic T cell and antigen presenting myeloid cell interactions, only after combination therapy, which is mirrored in a murine model of triple negative breast cancer.

RESUMEN

BACKGROUND: Older women with early-stage estrogen receptor-positive (ER+) invasive breast cancer (IBC) are at risk for overtreatment. Guidelines allow for sentinel lymph node biopsy (SLNB) and radiotherapy omission after breast-conserving surgery (BCS) for women 70 years of age or older with T1, clinical node negativity (cN0), and ER+ IBC. The study objective was to evaluate radiotherapy and SLNB de-implementation in older women with low-risk IBC after the resource limitations of the COVID-19 pandemic. METHODS: An institutional database was analyzed to identify women 70 years of age or older who received BCS for IBC from 2012 to 2022. The patients were divided into two cohorts: (1) patients with low-risk IBC (pT1, cN0, and ER+/HER2-) who were eligible for radiotherapy and SLNB omission and (2) patients with high-risk IBC (pT2-T4, cN+, ER-, or HER2+) who were ineligible for therapy omission. Clinicopathologic variables in both cohorts were analyzed. RESULTS: The study enrolled 881 patients. For the patients with low-risk IBC, the annual rates of radiotherapy were stable from 2012 to 2019. However, radiotherapy utilization decreased significantly from 2020 to 2022 (58% in 2012 vs 36% in 2022; p = 0.04). In contrast, radiotherapy usage among the patients with high-risk IBC was stable from 2012 to 2022 (79% in 2012 vs 79% in 2022; p = 0.95). Among the patients with low-risk IBC, SLNB rates decreased from 86% in 2012 to 56% in 2022, but this trend predated those in 2020. The factors significantly associated with SLNB and receipt of radiotherapy among the patients with low-risk IBC were younger age, larger tumors, grade 3 disease, and involved nodal status (p < 0.01). CONCLUSION: This study demonstrated appropriate and sustained de-escalation of radiotherapy in older women with low-risk IBC after the COVID-19 pandemic.

RESUMEN

BACKGROUND: There is no consensus on the use of postoperative antibiotic prophylaxis (PAP) after mastectomy with indwelling drains. We explored the utility of continued PAP in reducing surgical site infection (SSI) rates after mastectomy without immediate reconstruction and with indwelling drains. PATIENTS AND METHODS: A multicenter, two-armed, randomized control superiority trial was conducted in Pakistan. We enrolled all consenting adult patients undergoing mastectomy without immediate reconstruction. All patients received a single preoperative dose of cephalexin within 60 min of incision, and postoperatively were randomized to receive either continued PAP using cephalexin (intervention) or a placebo (control) for the duration of indwelling, closed-suction drains. The primary outcome was the development of SSI within 30 days and 90 days postoperatively. Secondary outcomes included study-drug-associated adverse events. Intention-to-treat analysis was performed using multivariable Cox regression. RESULTS: A total of 369 patients, 180 (48.8%) in the intervention group and 189 (51.2%) in the control group, were included in the final analysis. Overall cumulative SSI rates were 3.5% at 30 days and 4.6% at 90 days postoperatively. PAP was not associated with SSI reduction at 30 (hazard ratio, HR 1.666 [95% confidence interval CI 0.515-5.385]) or 90 (1.575 [0.558-4.448]) days postoperatively, or with study-drug-associated adverse effects (0.529 [0.196-1.428]). CONCLUSIONS: Continuing antibiotic prophylaxis for the duration of indwelling drains after mastectomy without immediate reconstruction offers no additional benefit in terms of SSI reduction. There is a need to update existing guidelines to provide clearer recommendations regarding use of postoperative antibiotic prophylaxis after mastectomy in the setting of indwelling drains.

RESUMEN

Colon cancer with high microsatellite instability is characterized by a high tumor mutational burden and responds well to immunotherapy. Mutations in polymerase ɛ, a DNA polymerase involved in DNA replication and repair, are also associated with an ultra-mutated phenotype. We describe a case where a patient with POLE-mutated and hypermutated recurrent colon cancer was treated with pembrolizumab. Treatment with immunotherapy in this patient also led to the clearance of circulating tumor DNA (ctDNA). ctDNA is beginning to emerge as a marker for minimal residual disease in many solid malignancies, including colon cancer. Its clearance with treatment suggests that the selection of pembrolizumab on the basis of identifying a POLE mutation on next-generation sequencing may increase disease-free survival in this patient.

RESUMEN

INTRODUCTION: Breast surveillance in patients with BRCA mutations include mammography (MMG) and MRI. Patients may elect to undergo risk-reducing bilateral prophylactic mastectomies (BPM). Sentinel lymph node biopsies (SLNB) are frequently performed and associated with increased morbidity. This study sought to determine the correlation between preoperative imaging and the final pathology and evaluate the role of SLNB in these high-risk patients. METHODS: A prospective database identified BRCA patients who underwent BPM between 2006 and 2022. Imaging, pathology, and operative reports were reviewed. RESULTS: 170 patients with BRCA 1/2 mutations were identified. 162 (95.3%) had imaging within one year of BPM. Of these, 28 (17.3%) patients had a MMG/ultrasound, 53 (32.7%) had an MRI, and 81 (50%) had both; 21/162 (13.0%) patients had abnormal imaging. Bilateral SLNB were performed in 31 (18.2%) patients, of which 7 had abnormal imaging; unilateral SLNB were performed in 4 (2.4%) patients, of which 3 had abnormal imaging. 11/170 (6.4%) patients had a malignancy and only one (9%) of these patients had imaging abnormalities. 1/170 (0.6%) patient had an invasive carcinoma requiring an axillary lymph node dissection (ALND), and 10/170 (5.9%) patients had ductal carcinoma in situ (DCIS). 25/170 (14.7%) had ADH/ALH. Only 7/170 (4.1%) patients had imaging abnormalities and abnormal pathology. All SLNB and ALND performed demonstrated no metastatic disease. DISCUSSION: There is a high rate of discordance between preoperative imaging prior to surgery in BRCA patients undergoing prophylactic mastectomies and final pathology. This study does not support routine SLNB at the time of BPM.

RESUMEN

BACKGROUND: The growing adoption of robotic-assisted surgery mandates residents must acquire robotic skills. No standardized curriculum for robotic surgery exists. Therefore, programs have developed their own curricula, which are often unstructured and based on resource availability. With this strategy programs may not adhere to scholarly approaches in curriculum development. We aimed to obtain a multi-institutional needs assessment to address training needs and identify integral components of a formalized robotic surgery curriculum. METHODS: A 10-question survey was distributed to general surgery residents. A separate 7-question survey was sent to robotic faculty surgeons at 3 institutions. Survey questions queried demographics, opinions regarding robotic training, proficiency definitions, and identification of procedures and instructional strategies for a curriculum. Mann- Whitney U test and Fisher's exact test were performed to compare responses amongst residents and faculty. Spearman's correlation was used to identify relationships between experience or post-graduate year (PGY) with response selection. RESULTS: Both residents and faculty believed robotic training should start in the PGY1 (55.1% vs 52%; p = 0.58). Faculty recognized robotic training to be more important compared to residents (84% vs 58.1%; p < 0.05). Both groups considered a minimum of 21 to 40 robotic cases to be sufficient exposure during training (p = 0.30). Cholecystectomy (82.4% vs 72%; p = 0.261), ventral hernia repair (89.2% vs 88%; p = 1.0), inguinal hernia repair (91.9% vs 92%; p = 1.0), and right colectomy (83.8% vs 80%; p = 0.7) were considered to be the most appropriate robotic procedures during training. Both groups concurred that bedside (91.9% vs 100%; p = 0.33) and console skills training (97.3% vs 100%; p = 1.0), small group simulation (94.6% vs 72% p = 0.005), and independent practice (87.8% vs 92% p = 0.73), were instructional strategies vital to a curriculum. Faculty considered online didactic modules (96% vs 59.5%; p < 0.05) to be more important, whereas residents favored small group experiences for fundamental skills (94.6% vs. 72%; p < 0.05) and procedure-based simulation (96% vs 64%; p < 0.05). CONCLUSIONS: Our targeted needs assessment identified requisite components of a robotics curriculum, which are feasible and accepted by both residents and faculty. Medical educators can use this as a resource to develop a formal robotics training curriculum.

RESUMEN

BACKGROUND: Invasive lobular carcinoma (ILC) is associated with high re-excision rates following breast-conserving surgery (BCS). The correlation between lesion size on different imaging modalities and final tumor size has not been well characterized. METHODS: A prospective database of patients with stage I-III breast cancer undergoing BCS between 2006 and 2016 was reviewed. Pearson correlation analysis was used to correlate tumor size on breast imaging to final pathology. RESULTS: Of these, 111 patients with ILC were identified. Mean lesion size was 1.93 cm for MMG, 1.61 cm for US, and 2.51 cm for MRI. Mean tumor size on surgical excision was 2.64 cm. The correlation coefficient between pathology and the different imaging modalities were as follows: MMG .17, US 0.37, and MRI .58. Actual tumor size was underestimated by 1 cm in 27.1% of MMGs, 50% of USs, and in 13.3% of MRIs. 38 patients (34.2%) underwent re-excision. No differences in re-excision rates were noted in patients with and without MRI, 30.3% vs 40.0%, respectively (P = .31). CONCLUSION: While MRI provides a better estimate of tumor size than MMG and US, the size of the tumor on imaging only weakly correlated with pathology. The use of MRI does not decrease re-excision rates.

RESUMEN

Importance: Characteristics of outstanding graduating surgical residents are currently undefined. Identifying these qualities may be important in guiding resident selection and resident education. Objective: To determine characteristics that are most strongly associated with being rated as an outstanding graduating surgical resident. Design, Setting, and Participants: The multi-institutional study had 3 phases. First, an expert panel developed a list of characteristics embodied by top graduating surgical residents. Second, groups of faculty from 14 US general-surgery residency programs ranked 2017 through 2020 graduates into quartiles of overall performance. Third, faculty evaluated their graduates on each characteristic using a 5-point Likert scale. Data were analyzed using Spearman rank-order correlation to identify which individual characteristics were associated with overall graduate performance. A least absolute shrinkage and selection operator (LASSO) ordinal regression was performed to select a parsimonious model to predict the outcome of overall performance rating from individual characteristic scores. Main Outcome and Measures: Surgical educators' rankings of general surgery residency graduates' overall performance. Results: Fifty faculty from 14 US residency programs with a median of 13 (range, 5-30) years of surgical education experience evaluated 297 general surgery residency graduates. Surgical educators identified 21 characteristics that they believed outstanding graduating surgical residents possessed. Two hundred ninety-seven surgical residency graduates were evaluated. Higher scores in every characteristic correlated with better overall performance. Characteristics most strongly associated with higher overall performance scores were surgical judgment (r = 0.728; P < .001), leadership (r = 0.726; P < .001), postoperative clinical skills (r = 0.715; P < .001), and preoperative clinical skills (r = 0.707; P < .001). The remainder of the characteristics were moderately associated with overall performance. The LASSO regression model identified 3 characteristics from which overall resident performance could be accurately predicted without measuring other qualities: surgical judgment (odds ratio [OR] per 1 level of 5-level Likert scale OR, 1.27; 95% CI, 1.03-1.51), leadership (OR, 1.27; 95% CI, 1.06-1.48), and medical knowledge (OR, 1.16; 95% CI, 1.01-1.33). Conclusions and Relevance: All individual characteristics identified by surgical educators as being qualities of outstanding graduating surgical residents were positively associated with overall graduate performance. Surgical judgment and leadership skills had the strongest individual associations. Assessment of only 3 qualities (surgical judgment, leadership, and medical knowledge) were required to predict overall resident performance ratings. These findings highlight the importance of developing specific surgical judgment and leadership skills curricula and assessments during surgical residency.
