Defining the Disparity: A Multi-Institutional Analysis of Factors Associated With Decreased Resident Operative Experience.

INTRODUCTION: Technical learning in surgical training is multifaceted and existing literature suggests a positive relationship between case volume and proficiency. Little is known about factors associated with a decreased volume of operative experience. This study aimed to identify resident and program factors associated with general surgery residents (GSR) in the bottom quartile of logged case volume upon program completion. METHODS: A post hoc analysis of a multicenter study was used to examine case logs for categorical GSR. Participants included graduates between 2010 and 2020 from 20 programs. Residents below and above the 25th percentile for total operative volume were compared. RESULTS: The present study includes 1343 GSR who graduated over the 11-y period. In total, 336 residents were below the 25th percentile and 1007 residents were above the 25th percentile. Those below the 25th percentile were more likely to be female (41% versus 34%, P = 0.02), identify as underrepresented in medicine (22% versus 14%, P < 0.01), and pursue fellowship (86% versus 80%, P = 0.01) compared to those above the 25th percentile. Residents below the 25th percentile were more likely to have graduated from a low volume program (55% versus 25%, P < 0.01) and from top National Institutes of Health funded institutions (57% versus 52%, P = 0.01). CONCLUSIONS: This study identified individual and program characteristics associated with lower operative volume of GSR. Understanding such characteristics will aid surgical educators to achieve better equity in training.

Are General Surgery Residencies Preparing Graduates for the Practice of Today's General Surgeon? An Analysis of American Board of Surgery Data From Applicants and Re-certifying Surgeons.

OBJECTIVE: To compare the operative experience of general surgery residents and practicing general surgeons. SUMMARY OF BACKGROUND DATA: The scope of general surgery has evolved, yet it remains unknown whether residents are being exposed to the right mix of operations during residency. METHODS: A retrospective review of operative case logs submitted to the American Board of Surgery by US general surgery graduates and practicing general surgeons from 2013 to 2017 was performed. The operative experience of both cohorts was calculated as a proportion of total experience and ranked by frequency. The proportional experience between cohorts was analyzed using factorial analysis of variance. RESULTS: During the 5-year period, 5482 graduates applied for initial American Board of Surgery certification, and 4152 diplomates applied for recertification. Among all operative domains, the graduate experience was similar to that of diplomates in 6 of 12 areas (abdomen, alimentary tract, endoscopy, endocrine, other, skin/soft tissue; all P > 0.05). Residents have a greater experience in subspecialty areas (pediatric, thoracic, trauma, vascular, and plastic) at the expense of fewer breast procedures (all P < 0.05). The 30 operations most commonly performed by graduates comprised 67% of their total operative experience. Among these, residents performed 25 cases ≥10 times, 14 cases ≥20 times, and 7 cases ≥40 times. CONCLUSIONS: The operative experience of graduating US general surgery residents is largely similar to that of practicing general surgeons, particularly for core general surgery domains. These data offer reassurance that surgical training in the modern era appropriately exposes residents to the operations they may perform in practice.

Disparities in the Operative Experience Between Female and Male General Surgery Residents: A Multi-institutional Study From the US ROPE Consortium.

OBJECTIVE: To examine differences in resident operative experience between male and female general surgery residents. BACKGROUND: Despite increasing female representation in surgery, sex and gender disparities in residency experience continue to exist. The operative volume of male and female general surgery residents has not been compared on a multi-institutional level. METHODS: Demographic characteristics and case logs were obtained for categorical general surgery graduates between 2010 and 2020 from the US Resident OPerative Experience Consortium database. Univariable, multivariable, and linear regression analyses were performed to compare differences in operative experience between male and female residents. RESULTS: There were 1343 graduates from 20 Accreditation Council for Graduate Medical Education-accredited programs, and 476 (35%) were females. There were no differences in age, race/ethnicity, or proportion pursuing fellowship between groups. Female graduates were less likely to be high-volume residents (27% vs 36%, P < 0.01). On univariable analysis, female graduates performed fewer total cases than male graduates (1140 vs 1177, P < 0.01), largely due to a diminished surgeon junior experience (829 vs 863, P < 0.01). On adjusted multivariable analysis, female sex was negatively associated with being a high-volume resident (OR = 0.74, 95% CI: 0.56 to 0.98, P = 0.03). Over the 11-year study period, the annual total number of cases increased significantly for both groups, but female graduates (+16 cases/year) outpaced male graduates (+13 cases/year, P = 0.02). CONCLUSIONS: Female general surgery graduates performed significantly fewer cases than male graduates. Reassuringly, this gap in operative experience may be narrowing. Further interventions are warranted to promote equitable training opportunities that support and engage female residents.

General Surgery Residency Virtual Recruitment During the Pandemic: An Analysis of Applicant Surveys.

INTRODUCTION: The COVID-19 pandemic forced a sudden change from in-person to virtual interviews for the general surgery residency match. General surgery programs and applicants adopted multiple strategies to best mimic in-person recruitment. The purpose of this study was to evaluate applicant opinions of the virtual recruitment format. MATERIALS AND METHODS: Postinterview survey responses for applicants interviewing at a single general surgery residency program in the 2020-2021 and 2021-2022 cycles were evaluated. All interviewed applicants were sent an anonymous survey assessing the virtual interview structure, their impression of the program, and their opinions on recruitment in the future. RESULTS: The response rate was 31.2% (n = 60). Most (88.4%) respondents reported a more favorable view of the program after a virtual interview. Factors that were most likely to create a favorable impression were residents (89.6%) and culture (81.0%). 50.8% of applicants favored virtual-only interviews. The majority of applicants (60.3%), however, preferred the virtual interview remain a component of the application process, 34.4% recommended that virtual interviews be used as an initial screen before in-person invites, while 19.0% suggested applicants should interview in-person or virtually without penalty. 62.1% favored capping the number of interviews offered by programs and accepted by applicants. CONCLUSIONS: The virtual interview format for general surgery residency allows applicants to effectively evaluate a residency program. Applicants are in favor of a combination of virtual and in-person interviews in the future. Innovation in the recruitment process, including limiting the number of applications and incorporating virtual events, is supported by applicants.

Extinguishing burnout: National analysis of predictors and effects of burnout in abdominal transplant surgery fellows.

Burnout among surgeons has been attributed to increased workload and decreased autonomy. Although prior studies have examined burnout among transplant surgeons, no studies have evaluated burnout in abdominal transplant surgery fellows. The objective of our study was to identify predictors of burnout and understand its impact on personal and patient care during fellowship. A survey was sent to all abdominal transplant surgery fellows in an American Society of Transplant Surgeons-accredited fellowship. The response rate was 59.2% (n = 77) and 22.7% (n = 17) of fellows met criteria for burnout. Fellows with lower grit scores were more likely to exhibit burnout compared with fellows with higher scores (3.6 vs 4.0, P = .026). Those with burnout were more likely to work >100 hours per week (58.8% vs 27.6%, P = .023), have severe work-related stress (58.8% vs 22.4%, P = .010), consider quitting fellowship (94.1% vs 20.7%, P < .001), or make a medical error (35.3% vs 5.2%, P = .003). This national analysis of abdominal transplant fellows found that burnout rates are relatively low, but few fellows engage in self-care. Personal and program-related factors attribute to burnout and it has unacceptable effects on patient care. Transplant societies and fellowship programs should develop interventions to give fellows tools to prevent and combat burnout.

Evaluating the Impact of ESPAC-1 on Shifting the Paradigm of Pancreatic Cancer Treatment.

BACKGROUND: In 2004, the European Study Group for Pancreatic Cancer (ESPAC)-1 long-term data concluded that adjuvant chemotherapy provided a survival benefit for patients with pancreatic ductal adenocarcinoma (PDAC), whereas adjuvant chemoradiation was associated with worse overall survival. In this study, we investigated how long it took for US practice patterns to change following this trial. METHODS: The National Cancer Database was used to identify patients with stage I-III PDAC who underwent R0 or R1 resection followed by adjuvant chemotherapy or chemoradiation between 1998 and 2015. A multivariate analysis was performed to determine predictors of receiving adjuvant chemoradiation in the post-ESPAC-1 era. RESULTS: Between 1998 and 2015, adjuvant chemotherapy use increased from 2.9% to 51.6%, whereas adjuvant chemoradiation decreased from 49.5% to 22.9%. In 2010, adjuvant chemotherapy utilization surpassed that of chemoradiation. For patients diagnosed in the post-ESPAC-1 era, adjuvant chemotherapy (n = 7733) and chemoradiation (n = 6969) groups were compared. Patients who underwent adjuvant chemoradiation were younger, had private insurance, underwent surgery at nonacademic centers, and had more pathologically advanced cancers (all P < 0.01). After 2010, R1 resection was the strongest independent predictor of adjuvant chemoradiation use by multivariate analysis (OR 2.05, CI 1.8-2.3, P < 0.01). CONCLUSIONS: Adjuvant chemotherapy use exceeded that of adjuvant chemoradiation 6 y after the final publication of ESPAC-1 in 2004, highlighting the challenges of disseminating and adopting clinical data. After 2010, R1 disease was the most significant predictor of receiving adjuvant chemoradiation. Prospective studies are underway to definitively address the role of adjuvant chemoradiation in PDAC.

Hitting the Vasopressor Ceiling: Finding Norepinephrine Associated Mortality in the Critically Ill.

BACKGROUND: There is no consensus on what dose of norepinephrine corresponds with futility. The purpose of this study was to investigate the maximum infusion and cumulative doses of norepinephrine associated with survival for patients in medical and surgical intensive care units (MICU and SICU). MATERIALS AND METHODS: A retrospective review was conducted of 661 critically ill patients admitted to a large academic medical center who received norepinephrine. Univariate, multivariate, and area under the curve analyses with optimal cut offs for maximum infusion rate and cumulative dosage were determined by Youden Index. RESULTS: The population was 54.9% male, 75.8% white, and 58.7 ± 16.1 y old with 384 (69.8%) admitted to the MICU and 166 (30.2%) admitted to the SICU, including 38 trauma patients. Inflection points in mortality were seen at 18 mcg/min and 17.6 mg. The inflection point was higher in MICU patients at 21 mcg/min and lower in SICU patients at 11 mcg/min. MICU patients also had a higher maximum cumulative dosage of 30.7 mg, compared to 2.7 mg in SICU patients. In trauma patients, norepinephrine infusions up to 5 mcg/min were associated with a 41.7% mortality rate. CONCLUSION: A maximum rate of 18 mcg/min and cumulative dose of 17.6 mg were the inflection points for mortality risk in ICU patients, with SICU patients tolerating lower doses. In trauma patients, even low doses of norepinephrine were associated with higher mortality. These data suggest that MICU, SICU, and trauma patients differ in need for, response to, and outcome from escalating norepinephrine doses.

Outcomes of en bloc simultaneous liver-kidney transplantation compared to the traditional technique.

Simultaneous liver-kidney transplantation (SLKT) is indicated for patients with end-stage liver disease (ESLD) and concurrent renal insufficiency. En bloc SLKT is an alternative to traditional separate implantations, but studies comparing the two techniques are limited. The en bloc technique maintains renal outflow via donor infrahepatic vena cava and inflow via anastomosis of donor renal artery to donor splenic artery. Comparison of recipients of en bloc (n = 17) vs traditional (n = 17) SLKT between 2013 and 2017 was performed. Recipient demographics and comorbidities were similar. More recipients of traditional SLKT were dialysis dependent (82.4% vs 41.2%, P = .01) with lower baseline pretransplant eGFR (14 vs 18, P = .01). En bloc SLKT was associated with shorter kidney cold ischemia time (341 vs 533 minutes, P < .01) and operative time (374 vs 511 minutes, P < .01). Two en bloc patients underwent reoperation for kidney allograft inflow issues due to kinking and renal steal. Early kidney allograft dysfunction (23.5% in both groups), 1-year kidney graft survival (88.2% vs 82.4%, P = 1.0), and posttransplantation eGFR were similar between groups. In our experience, the en bloc SLKT technique is safe and feasible, with comparable outcomes to the traditional method.

Small Bowel Adenocarcinomas: Impact of Location on Survival.

BACKGROUND: Proximal (duodenal) small bowel adenocarcinomas have a worse prognosis than distal (jejuno-ileal) tumors, but differences in patient, tumor, and treatment factors between locations remain unclear. METHODS: Patients in the National Cancer Database with surgically resected pathologic stage I-IV small bowel adenocarcinomas between 2004 and 2015 were analyzed. Clinical stage IV patients were excluded. RESULTS: Proximal tumors (n = 3767) were more likely to be higher grade (OR 1.52, CI 1.22-1.85 for moderately; OR 1.83, CI 1.49-2.33 for poorly differentiated, P < 0.01 for both) and have positive lymph nodes (OR 2.04, CI 1.30-3.23, P < 0.01), while distal tumors (n = 3252) were likely to be larger (OR 1.31, CI 1.07-1.60 for size > 5 cm, P < 0.01). Proximal tumors were associated with worse overall survival (OS) and stage-specific survival compared with distal tumors (all P < 0.01). Cox regression analysis of the entire cohort showed worse survival with community versus academic cancer programs, higher comorbidity scores, pathologic stage IV, poorly differentiated histology, positive nodal or margin status, and proximal location, while female gender, larger tumor size, and chemotherapy predicted better survival. On separate Cox regression analyses of each location, neoadjuvant chemotherapy was associated with better OS in the proximal cohort (HR 0.70, CI 0.55-0.88, P < 0.01), while adjuvant chemotherapy was associated with better OS for both proximal (HR 0.49, CI 0.42-0.57, P < 0.01) and distal tumors (HR 0.68, CI 0.57-0.81, P < 0.01). CONCLUSIONS: Proximal small bowel adenocarcinomas are associated with worse overall and stage-specific survival. This may be due to tumor biologic differences as proximal tumors were more likely to have higher grade. Future studies should further investigate differences between proximal and distal tumors to guide targeted treatment algorithms.

Consumptive coagulopathy is associated with organ dysfunction during PICS.

Patients who survive the acute phase of sepsis can progress to persistent inflammation, immunosuppression, and catabolism syndrome (PICS). Although sepsis is characterized by early hypercoagulability and delayed hypocoagulability, coagulopathy during chronic critical illness is not fully understood. The objective of this study was to determine whether sepsis-induced PICS is associated with coagulation abnormalities. Using our previously described murine PICS model, outbred mice underwent cecal ligation and puncture, and coagulability was characterized after 8 days. We found that during PICS the spleen became markedly enlarged with increased splenocytes and splenic megakaryocytes without a concomitant increase in circulating platelets. Microscopy revealed a nearly sevenfold increase in pulmonary microvascular thrombi in PICS mice, along with significantly decreased pulmonary tidal volumes and inspiratory times and with significantly increased respiratory rates. Thromboelastometry showed that PICS mice had significantly delayed clot initiation time but increased clot firmness. Finally, PICS mice displayed delayed thrombin production and decreased overall thrombin concentrations. All together, these data demonstrate a general dysregulation of coagulation resulting in microthrombus formation and compromised lung function. On the basis of these findings, we propose that consumptive coagulopathy constitutes another cardinal feature of PICS and may contribute to the ongoing tissue damage and multiple organ failure that can occur in chronic critical illness.

Amitriptyline Reduces Inflammation and Mortality in a Murine Model of Sepsis.

BACKGROUND/AIMS: During sepsis, an unchecked pro-inflammatory response can be detrimental to the host. We investigated the potential protective effect of amitriptyline (AT). METHODS: We used two murine models of sepsis: Cecal ligation and puncture and endotoxemia following LPS challenge. Aural temperatures were taken and cytokines quantified by cytometric bead assay. Lung injury was determined histologically and by protein determination in bronchoalveolar lavage fluid. Cell accumulation in the peritoneum was analyzed by flow cytometry, as well as cytokine production and p38-phosphorylation. Neutrophil chemotaxis was evaluated using an in vitro transwell assay. RESULTS: Our findings demonstrate that AT-treated septic mice have improved survival and are protected from pulmonary edema. Treatment with AT significantly decreased serum levels of KC and monocyte chemoattractant protein-1, as well as the accumulation of neutrophils and monocytes in the peritoneum of septic mice. Peritoneal IL-10 levels in septic mice were increased upon AT treatment. Direct treatment of septic mice with IL-10 recapitulated the effects of AT. Endotoxemic mice also exhibited enhanced IL-10 production upon AT-administration and peritoneal macrophages were identified as the ATinfluenced producers of IL-10. Treatment of these cells with AT in vitro resulted in increased p38-phosphorylation and IL-10 generation, whereas ceramide and p38 inhibition had the opposite effect. CONCLUSION: Altogether, AT treatment improved survival, increased IL-10 levels, and mitigated a pro-inflammatory response during sepsis. We conclude that AT is a promising therapeutic to temper inflammation during septic shock.

Incidence and Long-term Outcomes of Patients Requiring Early Reoperation After HIPEC.

BACKGROUND: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (HIPEC) remains a formidable operation associated with considerable morbidity. It is unclear how often these patients require reoperation for postoperative complications and if the need for reoperations leads to worse long-term outcomes. METHODS: The Peritoneal Surface Malignancy Database at a single center was retrospectively queried. Out of 149 entries, 141 HIPECs performed between 2012 and 2018 met inclusion criteria. Patients were categorized based on early reoperation (<60 d after HIPEC), and demographic and tumor factors were compared using univariate analyses. Recurrence was calculated for patients with complete cytoreduction and overall survival analyzed using the Kaplan-Meier method. RESULTS: There were 15 reoperations after 141 HIPECs (10.6%). Median duration between HIPEC and reoperation was 18 d. Indications for reoperation included intra-abdominal infection (n = 5), bowel obstruction (n = 4), wound infection (n = 3), bleeding (n = 2), and evisceration (n = 1). There were no identified patient- or tumor-related risk factors for reoperation. Reoperations were associated with longer hospital length of stay (19 versus 9 d, P = 0.005) and 30-d readmissions (46.7% versus 12.8%, P = 0.003). There was no significant difference in 3-year recurrence-free survival, but there was a significant association between reoperation and 3-year overall survival (38.0% versus 71.9%, P = 0.03). CONCLUSIONS: Complications requiring reoperation after HIPEC lead to increased short-term morbidity, longer hospital length of stay, and most importantly, reduced overall survival. Further studies investigating interventions to decrease complications and reduce reoperation rates are needed to improve outcomes after HIPEC.

The Impact of Tumor Location on Resection and Survival for Pancreatic Ductal Adenocarcinoma.

BACKGROUND: Differences in clinical staging and survival among pancreatic head, body, and tail cancers are not well defined. We aim to identify the prognostic relevance of primary tumor location in patients undergoing treatment for pancreatic ductal adenocarcinoma (PDAC). MATERIALS AND METHODS: The National Cancer Database was used to identify patients with PDAC from 1998 to 2011 (n = 175,556). Patients were categorized by primary tumor site into head (67.5%, n = 118,343), body (15.5%, n = 27,218), and tail (17.0%, n = 29,885) groups. Univariate and Cox regression analyses were used to determine covariates associated with overall survival (OS). RESULTS: Patients with head PDAC presented with earlier stage disease (39.2% Stage I/II versus 19.7% versus 16.0%, P < 0.001) and underwent resection more often (27.9% versus 10.7% versus 17.0%, P < 0.001) than those with body or tail tumors. Of surgically resected PDAC, those localized to the head had advanced pathologic stage (84.8% stage II/III versus 66.6% versus 65.6%, P < 0.001), higher nodal positivity (64.9% versus 45.8% versus 45%, P < 0.001), and worse tumor grade (35.9% poorly differentiated versus 29.5% versus 27.8%, P < 0.001). Despite increased utilization of adjuvant therapies (54.4% versus 45.6% versus 42.0%, P < 0.001), patients with head PDAC had inferior OS compared with those with body and tail tumors (P < 0.001). CONCLUSIONS: When examining patients with PDAC undergoing resection, tumor localization to the head is associated with improved resectability because they present earlier. Of resected PDACs, however, those localized to the head have worse OS compared with body and tail tumors. This discrepancy may represent a combination of lead time and selection biases and biologic differences between tumor sites.

Perioperative blood transfusions following hepatic lobectomy: A national analysis of academic medical centers in the modern era.

BACKGROUND: The purpose of the study was to characterize the prevalence and impact of perioperative blood use for patients undergoing hepatic lobectomy at academic medical centers. METHODS: The University HealthSystem Consortium (UHC) database was queried for hepatic lobectomies performed between 2011 and 2014 (n = 6476). Patients were grouped according to transfusion requirements into high (>5 units, 7%), medium (2-5 units, 6%), low (1 unit, 8%), and none (0 units, 79%) during hospital stay for comparison of outcomes. RESULTS: Over 20% of patients undergoing hepatic lobectomy received blood perioperatively, of which 35% required more than 5 units. Patients with high transfusion requirements had increased severity of illness (p < 0.01). High transfusion requirements correlated with increased readmission rates (23.4% vs. 19.2% vs. 16.6% vs. 13.5%), total direct costs ($31,982 vs. $20,859 vs. $19,457 vs. $16,934), length of stay (9 days vs. 8 vs. 7 vs. 6), and in-hospital mortality (10.8% vs. 2.0% vs. 0.9% vs. 2.0%) compared to medium, low, and no transfusion amounts (all p < 0.01). Neither center nor surgeon volume were associated with transfusion use. CONCLUSION: High transfusion requirements after hepatic lobectomy in the United States are associated with worse perioperative quality measures, but may not be influenced by center or surgeon volume.

Resident perspectives on the role of gender in operative experience during general surgery residency training: A mixed-methods study.

BACKGROUND: It remains unclear why female general surgery residents perform fewer cases than male peers. This exploratory study investigated possible contributors to gender-based disparities and solutions for improving equity in operative experience. METHODS: Surveys, including Likert scale and free-text questions, were distributed to 21 accredited general surgery residency programs. RESULTS: There were 96 respondents, of whom 69% were female. 22% of females personally experienced barriers to operative experience versus 13% of males (p â€‹= â€‹0.41), while 52% of female residents believed operative training was affected by gender (p â€‹= â€‹0.004). Inductive analysis revealed the most common barrier to operating room participation was floor work/clinical tasks. The most common barrier for female residents was perceived sexism/gender bias, with subthemes of "misidentification," "feeling unwelcome," and "poor trust/autonomy." To improve parity, residents proposed structured program-level review, feedback, and transparent expectations about case assignments. CONCLUSION: Female general surgery residents believe gender bias impacts training. Further mixed-methods research is crucial to determine the cause of gender-based disparities in operative experience.

Examining the impact of COVID-19 restrictions on the operative volumes of US general surgery residents.

BACKGROUND: In March 2020, the COVID-19 virus global pandemic forced healthcare systems to institute regulations including the cancellation of elective surgical cases, which likely decreased resident operative experience. The objective of this study was to determine whether the COVID-19 pandemic affected operative experiences of US general surgery residents. METHODS: The operative experience of general surgery residents was examined nationally and locally. Aggregate Accreditation Council for Graduate Medical Education (ACGME) case logs for 2018 to 2019 (pre-COVID) and 2019 to 2020 (COVID) graduates were compared using national mean cumulative operative volume for total major and surgeon chief cases. Locally, ACGME case logs were used to analyze the operative experience among residents at a single, academic center. Average operative volumes per month per resident during peak COVID-19 quarantine months were compared with those the previous year. RESULTS: Compared with 2019 graduates, 2020 graduates completed 1.5% fewer total major cases (1055 ± 155 vs 1071 ± 150, P = .011). This was most evident during chief year, with 8.4% fewer surgeon chief cases logged in 2020 compared with 2019 (264 ± 67 vs 289 ± 69, P < .001). Institutional data revealed that during the peak of the pandemic, residents across all levels completed 42.5% fewer total major operations (12 ± 11 vs 20 ± 14, P < .001). This effect was more pronounced among junior residents compared with senior and chief residents. CONCLUSION: The COVID-19 pandemic was associated with decreased resident case volume. The ramifications of the COVID-19 pandemic for operative competency and autonomy should be carefully examined.

Gender and ethnic diversity in academic general surgery department leadership.

BACKGROUND: Diversity in surgery has been shown to improve mentorship and patient care. Diversity has improved among general surgery (GS) trainees but is not the case for departmental leadership. We analyzed the race and gender distributions across leadership positions at academic GS programs. METHODS: Academic GS programs (n = 118) listed by the Fellowship and Residency Electronic Interactive Database Access system were included. Leadership positions were ascertained from department websites. Gender and race were determined through publicly provided data. RESULTS: Ninety-two (79.3%) department chairs were white and 99 (85.3%) were men. Additionally, 88 (74.6%) program directors and 34 (77.3%) vice-chairs of education were men. A higher proportion of associate program directors were women (38.5%). Of 787 division-chiefs, 73.4% were white. Only trauma had >10% representation from minority surgeons. Women represented >10% of division chiefs in colorectal, thoracic, pediatric, and plastic/burn surgery. CONCLUSION: Diversity among GS trainees is not yet reflected in departmental leadership. Effort is needed to improve disparities in representation across leadership roles.

Omission of Adjuvant Chemotherapy in Rectal Cancer Patients with Pathologic Complete Response: a National Analysis.

BACKGROUND: An increasing number of patients achieve a pathologic complete response (pCR) after neoadjuvant chemoradiation for locally advanced rectal cancer. Consensus guidelines continue to recommend oncologic resection followed by adjuvant chemotherapy in these patients. We hypothesize that there is significant variability in compliance with this recommendation. METHODS: The National Cancer Database was queried from 2006 to 2015 for patients with locally advanced rectal cancer who underwent neoadjuvant chemoradiation followed by oncologic resection with a pCR (ypT0N0). Hierarchical logistic regression models were used to generate risk and reliability-adjusted rates of adjuvant chemotherapy utilization in patients with pCR at each hospital. RESULTS: In total, 2421 pCR patients were identified. Five-year overall survival was improved in pCR patients who received adjuvant chemotherapy compared with those who did not (92 vs. 85%, p < 0.01). Multivariate analysis indicated that improvement in overall survival remained associated with adjuvant chemotherapy (HR 0.60, 95% CI 0.44-0.82, p < 0.01). The mean adjuvant chemotherapy utilization rate among hospitals was 32%. There was an upward trend in use over the past decade, but two-thirds still do not receive the recommended therapy. High chemotherapy utilizer hospitals were more likely to be academic centers (54.9 vs. 45.9%, p < 0.01) when compared with low chemotherapy utilizers. CONCLUSION: Adjuvant chemotherapy is associated with improved survival in rectal cancer patients with pCR following neoadjuvant chemoradiation and oncologic resection. However, utilization among centers in the USA was only 32% with significant variability across centers. National efforts are needed to standardize treatment patterns according to national guidelines.

Acquisition and retention of surgical skills taught during intern surgical boot camp.

BACKGROUND: Surgical residencies have implemented boot-camps for early acquisition of basic technical skills for interns. However, educators worry that retention is poor. We hypothesized that a structured boot-camp curriculum would improve skills. METHODS: Interns underwent eight boot-camp sessions at the beginning of residency. Interns completed pre-, post-boot-camp, and end-of-year skills assessments, as well as post-boot camp and end-of-year porcine procedure labs. Proficiency was measured on a 5-point scale and by completion time. RESULTS: After boot-camp, interns improved all domains of knot-tying. Median time decreased for skin-closure (8.3 vs 9.9 min, p < 0.01), peg transfer (57 vs 87 s, p < 0.01), intracorporeal (178 vs 300 s, p < 0.01), and extracorporeal knot-tying (140 vs 259 s, p < 0.01). At the end-of-year assessment, interns exhibited retention of all skills and improved in knot-tying and central line skills. During the retention porcine lab, interns progressed basic but not complex skills. CONCLUSIONS: An eight-week boot-camp effectively improved technical skills among surgery interns. Interns retained all skills and improved upon techniques frequently practiced during intern year.
