An Empirical National Assessment of the Learning Environment and Factors Associated With Program Culture

Ellis, Ryan J; Hewitt, D Brock; Hu, Yue-Yung; Johnson, Julie K; Merkow, Ryan P; Yang, Anthony D; Potts, John R; Hoyt, David B; Buyske, Jo; Bilimoria, Karl Y
OBJECTIVES:To empirically describe surgical residency program culture and assess program characteristics associated with program culture. SUMMARY BACKGROUND DATA:Despite concerns about the impact of the learning environment on trainees, empirical data have not been available to examine and compare program-level differences in residency culture. METHODS:Following the 2018 American Board of Surgery In-Training Examination, a cross-sectional survey was administered to all US general surgery residents. Survey items were analyzed using principal component analysis to derive composite measures of program culture. Associations between program characteristics and composite measures of culture were assessed. RESULTS:Analysis included 7387 residents at 260 training programs (99.3% response rate). Principal component analysis suggested that program culture may be described by 2 components: Wellness and Negative Exposures. Twenty-six programs (10.0%) were in the worst quartile for both Wellness and Negative Exposure components. These programs had significantly higher rates of duty hour violations (23.3% vs 11.1%), verbal/physical abuse (41.6% vs 28.6%), gender discrimination (78.7% vs 64.5%), sexual harassment (30.8% vs 16.7%), burnout (54.9% vs 35.0%), and thoughts of attrition (21.6% vs 10.8%; all P < 0.001). Being in the worst quartile of both components was associated with percentage of female residents in the program (P = 0.011), but not program location, academic affiliation, size, or faculty demographics. CONCLUSIONS:Residency culture was characterized by poor resident wellness and frequent negative exposures and was generally not associated with structural program characteristics. Additional qualitative and quantitative studies are needed to explore unmeasured local social dynamics that may underlie measured differences in program culture.

Risk factors for post-pancreaticoduodenectomy delayed gastric emptying in the absence of pancreatic fistula or intra-abdominal infection

Ellis, Ryan J; Gupta, Aakash R; Hewitt, D Brock; Merkow, Ryan P; Cohen, Mark E; Ko, Clifford Y; Bilimoria, Karl Y; Bentrem, David J; Yang, Anthony D
BACKGROUND AND OBJECTIVES/OBJECTIVE:Delayed gastric emptying (DGE) occurs commonly following pancreaticoduodenectomy (PD), but the rate of DGE in the absence of other intra-abdominal complications is poorly understood. The objectives of this study were to define the incidence of DGE and identify risk factors for DGE in patients without pancreatic fistula or other intra-abdominal infections. METHODS:Retrospective cohort study utilizing the American College of Surgeons National Surgical Quality Improvement Program pancreatectomy variables to identify patients with DGE following PD without evidence of fistula or intra-abdominal infection. Multivariable models were developed to assess preoperative, intraoperative, and technical factors associated with DGE. RESULTS:The rate of DGE was 11.7% in 10502 cases without pancreatic fistula or intra-abdominal infection. Patients were more likely to develop DGE if age ≥75 (odds ratio [OR], 1.22; P = 0.003), male (OR, 1.29; P < 0.001), underwent pylorus-sparing PD (OR, 1.27; P = 0.004), or had a prolonged operative time (OR, 1.38 if greater than seven vs less than 5 hours; P = 0.005). Factors not associated with DGE included BMI, pathologic indication, and surgical approach. CONCLUSION/CONCLUSIONS:The incidence of DGE after PD is notable even in patients without other abdominal complications. Identification of patients at increased risk for DGE may aid patient counseling as well as decisions regarding surgical technique, enteral feeding access, and enhanced-recovery pathways.

The effect of smoking on 30-day outcomes in elective hernia repair

DeLancey, John O; Blay, Eddie; Hewitt, D Brock; Engelhardt, Kathryn; Bilimoria, Karl Y; Holl, Jane L; Odell, David D; Yang, Anthony D; Stulberg, Jonah J
BACKGROUND:Adverse postoperative outcomes related to smoking are well established, yet current smokers continue to be offered elective surgery in the US. It is unknown whether patients undergoing low-risk, elective procedures, who actively smoke experience increased risk of complications. We sought to determine the increased burden of complications following elective hernia repair procedures in patients identified as current smokers. METHODS:We identified patients undergoing elective incisional, inguinal, umbilical, or ventral hernia repair from 2011 to 2014 using the American College of Surgeons National Surgical Quality Improvement Project (ACS NSQIP) database. Multivariable logistic regression analysis was used to examine the association between current smoking and 30-day postoperative outcomes, adjusting for demographics and comorbidities. RESULTS:Of 220,629 patients who underwent elective hernia repair, 40,446 (18.3%) self-identified as current smokers within the past 12 months. Current smokers experienced an increased likelihood (Odds Ratio [95% Confidence interval]) of reoperation (OR 1.23 [95% CI 1.11-1.36]), readmission (OR 1.24 [95% CI 1.16-1.32]), and death (OR 1.53 [95% CI 1.06-2.22]). Furthermore, smokers experienced an increased risk of postoperative pulmonary, infectious, and wound complications, but there was no increased risk of requiring transfusion or of postoperative cardiac or thromboembolic events. CONCLUSIONS:Current smokers were more likely to experience serious postoperative complications within 30 days. Given the volume of elective hernia surgery performed in the US, encouraging smoking cessation prior to offering elective repair could reduce postoperative complications, reoperation, readmission, and mortality.

National practice patterns of completion lymph node dissection for sentinel node-positive melanoma

Hewitt, D Brock; Merkow, Ryan P; DeLancey, John Oliver; Wayne, Jeffrey D; Hyngstrom, John R; Russell, Maria C; Gerami, Pedram; Balch, Charles M; Bilimoria, Karl Y
BACKGROUND AND OBJECTIVES/OBJECTIVE:Close observation may be an appropriate alternative to completion lymph node dissection (CLND) for selected patient populations, especially those with minimal tumor burden in the sentinel lymph node (SLN). In this study, we examined the practice patterns of CLND utilization. METHODS:Using the National Cancer Database, we examined CLND utilization in SLN-positive patients diagnosed with clinically node-negative Stage III melanoma from 2012 to 2015. Hierarchical logistic regression models were constructed to assess the factors associated with observation after positive SLN biopsy (SLNB). RESULTS:Of the 131 171 patients identified, 55 688 (42.5%) underwent SLNB and 7200 (12.9%) had an SLN with a metastatic disease. CLND was performed in 57.0% of the patients with a positive SLNB. Patients were more likely to forgo CLND if the primary tumor was located on the lower extremity (odds ratio [OR], 1.65, 95% confidence interval [CI], 1.40-1.94), were older (P < 0.001), had multiple comorbidities (OR, 1.61, 95% CI, 1.19-2.20), or were diagnosed with melanoma in 2015 (OR, 1.33, 95% CI, 1.13-1.56 vs 2012). CONCLUSIONS:CLND utilization varied based on patient factors and decreased over time. As evidence supports close observation in selected patient populations with low SLN tumor burden, monitoring is needed to ensure that CLND is performed in the appropriate patient populations. However, this will require improvements in the data collected by cancer registries.

Gender Differences in Utilization of Duty-hour Regulations, Aspects of Burnout, and Psychological Well-being Among General Surgery Residents in the United States

Dahlke, Allison R; Johnson, Julie K; Greenberg, Caprice C; Love, Remi; Kreutzer, Lindsey; Hewitt, Daniel B; Quinn, Christopher M; Engelhardt, Kathryn E; Bilimoria, Karl Y
OBJECTIVE:The aim of the study was to (1) assess differences in how male and female general surgery residents utilize duty-hour regulations and experience aspects of burnout and psychological well-being, and (2) to explore reasons why these differing experiences exist. BACKGROUND:There may be differences in how women and men enter, experience, and leave residency programs. METHODS:A total of 7395 residents completed a survey (response rate = 99%). Logistic regression models were developed to examine the association between gender and resident outcomes. Semistructured interviews were conducted with 42 faculty and 56 residents. Transcripts were analyzed thematically using a constant comparative approach. RESULTS:Female residents reported more frequently staying in the hospital >28 hours or working >80 hours in a week (≥3 times in a month, P < 0.001) and more frequently feeling fatigued and burned out from their work (P < 0.001), but less frequently "treating patients as impersonal objects" or "not caring what happens" to them (P < 0.001). Women reported more often having experienced many aspects of poor psychological well-being such as feeling unhappy and depressed or thinking of themselves as worthless (P < 0.01). In adjusted analyses, associations remained significant. Themes identified in the qualitative analysis as possible contributory factors to gender differences include a lack of female mentorship/leadership, dual-role responsibilities, gender blindness, and differing pressures and approaches to patient care. CONCLUSIONS:Female residents report working more, experiencing certain aspects of burnout more frequently, and having poorer psychological well-being. Qualitative themes provide insights into possible cultural and programmatic shifts to address the concerns for female residents.
