RESUMEN

BACKGROUND: Little is known about surgery for malignancy among people experiencing homelessness (PEH). Poor healthcare access may lead to delayed diagnosis and need for unplanned surgery. This study aimed to (1) characterize access to care among PEH, (2) evaluate postoperative outcomes, and (3) assess costs associated with surgery for malignancy among PEH. METHODS: This was a retrospective cohort study of patients in the Healthcare Cost and Utilization Project (HCUP) who underwent surgery in Florida, New York, or Massachusetts for gastrointestinal or lung cancer from 2016 to 2017. PEH were identified using HCUP's "Homeless" variable and ICD-10 code Z59. Multivariable regression models controlling patient and hospital variables evaluated associations between homelessness and postoperative morbidity, length of stay (LOS), 30-day readmission, and hospitalization costs. RESULTS: Of 67,034 patients at 566 hospitals, 98 (0.2%) were PEH. Most PEH (44.9%) underwent surgery for colorectal cancer. PEH more frequently underwent unplanned surgery than housed patients (65.3% vs 23.7%, odds ratio (OR) 5.17, 95% confidence interval (CI) 3.00-8.92) and less often were treated at cancer centers (66.0% vs 76.2%, p=0.02). Morbidity rates were similar between groups (20.4% vs 14.5%, p=0.10). However, PEH demonstrated higher odds of facility discharge (OR 5.89, 95% CI 3.50-9.78) and readmission (OR 1.81, 95% CI 1.07-3.05) as well as 67.7% longer adjusted LOS (95% CI 42.0-98.2%). Adjusted costs were 32.7% higher (95% CI 14.5-53.9%) among PEH. CONCLUSIONS: PEH demonstrated increased odds of unplanned surgery, longer LOS, and increased costs. These results underscore a need for improved access to oncologic care for PEH.

RESUMEN

BACKGROUND: An enriching learning environment is integral to resident wellness and education. Integrated vascular (VS) and general surgery (GS) residents share 18 months of core GS rotations during the postgraduate years 1-3 (PGY1-3); differences in their experiences may help identify practical levers for change. METHODS: We used a convergent mixed-methods design. Cross-sectional surveys were administered after the 2020 American Board of Surgery In-Training Examination and Vascular Surgery In-Training Examination, assessing eight domains of the learning environment and resident wellness. Multivariable logistic regression models identified factors associated with thoughts of attrition between categorical PGY1-3 residents at 57 institutions with both GS and VS programs. Resident focus groups were conducted during the 2022 Vascular Annual Meeting to elicit more granular details about the experience of the learning environment. Transcripts were analyzed using inductive and deductive logics until thematic saturation was achieved. RESULTS: Surveys were completed by 205 VS and 1198 GS PGY1-3 residents (response rates 76.8% for VS and 82.5% for GS). After adjusting for resident demographics, PGY level, and program type, GS residents were more likely than their VS peers to consider leaving their programs (odds ratio [OR]: 2.61, 95% confidence interval [CI]: 1.37-4.99). This finding did not persist after adjusting for differences in perceptions of the learning environment, specifically: GS residents had higher odds of mistreatment (OR: 1.99, 95% CI: 1.36-2.90), poorer work-life integration (OR: 2.88, 95% CI: 1.41-5.87), less resident camaraderie (OR: 3.51, 95% CI: 2.26-5.45), and decreased meaning in work (OR: 2.94, 95% CI: 1.80-4.83). Qualitative data provided insight into how the shared learning environment was perceived differently: (1) vascular trainees expressed that early specialization and a smaller, more invested faculty allow for an apprenticeship model with early operative exposure, hands-on guidance, frequent feedback, and thus early skill acquisition (meaning in work); (2) a smaller program is conducive to closer relationships with co-residents and faculty, increasing familiarity (camaraderie and work-life integration); and (3) due to increased familiarity with program leadership, vascular trainees feel more comfortable reporting mistreatment, allowing for prompt responses (mistreatment). CONCLUSIONS: Despite sharing a learning environment, VS and GS residents experience training differently, contributing to differential thoughts of attrition. These differences may be attributable to intrinsic features of the integrated training paradigm that are not easily replicated by GS programs, such as smaller program size and higher faculty investment due to early specialization. Alternative strategies to compensate for these inherent differences should be considered (eg, structured operative entrustment programs and faculty incentivization).

RESUMEN

BACKGROUND: Work-related pain is a known risk factor for vascular surgeon burnout. It risks early attrition from our workforce and is a recognized threat to the specialty. Our study aimed to understand whether work-related pain similarly contributed to vascular surgery trainee well-being. METHODS: A confidential, voluntary survey was administered after the 2022 Vascular Surgery In-Service Examination to trainees in all Accreditation Council for Graduate Medical Education-accredited vascular surgery programs. Burnout was measured by a modified, abbreviated Maslach Burnout Inventory; pain after a full day of work was measured using a 10-point Likert scale and then dichotomized as "no to mild pain" (0-2) vs "moderate to severe pain" (3-9). Univariable analyses and multivariable regression assessed associations of pain with well-being indicators (eg, burnout, thoughts of attrition, and thoughts of career change). Pain management strategies were included as additional covariables in our study. RESULTS: We included 527 trainees who completed the survey (82.2% response rate); 38% reported moderate to severe pain after a full day of work, of whom 73.6% reported using ergonomic adjustments and 67.0% used over-the-counter medications. Significantly more women reported moderate to severe pain than men (44.3% vs 34.5%; P < .01). After adjusting for gender, training level, race/ethnicity, mistreatment, and dissatisfaction with operative autonomy, moderate-to-severe pain (odds ratio, 2.52; 95% confidence interval, 1.48-4.26) and using physiotherapy as pain management (odds ratio, 3.06; 95% confidence interval, 1.02-9.14) were risk factors for burnout. Moderate to severe pain was not a risk factor for thoughts of attrition or career change after adjustment. CONCLUSIONS: Physical pain is prevalent among vascular surgery trainees and represents a risk factor for trainee burnout. Programs should consider mitigating this occupational hazard by offering ergonomic education and adjuncts, such as posture awareness and microbreaks during surgery, early and throughout training.

RESUMEN

INTRODUCTION: Burnout and mistreatment are prevalent among surgical residents with considerable program-level variation. Applicants consider "program reputation," among other factors, when ranking programs. Although highly subjective, the only available measure of program reputation is from a physician survey by Doximity. It is unknown how program reputation is associated with resident well-being and mistreatment. METHODS: Resident burnout and personal accomplishment were assessed via the 2019 post-American Board of Surgery In-Training Examination survey. Additional outcomes included mistreatment, thoughts of attrition, and suicidality. Residents were stratified into quartiles based on their program's Doximity reputation rank. Multivariable logistic regression models examined the relationship between each outcome with Doximity rank quartile. RESULTS: 6956 residents (85.6% response rate) completed the survey. Higher-ranked programs had significantly higher burnout rates (top-quartile 41.3% versus bottom-quartile 33.2%; odds ratio [OR] 1.35, 95% confidence interval [CI] 1.04-1.76). There was no significant difference in personal accomplishment by program rank (OR 1.26, 95% CI 0.86-1.85). There also was no significant association between program rank and sexual harassment (OR 0.90, 95% CI 0.70-1.17), gender discrimination (OR 1.14, 95% CI 0.86-1.52), racial discrimination (OR 1.18, 95% CI 0.91-1.54), or bullying (OR 1.03, 95% CI 0.76-1.40). Suicidality (P = 0.97) and thoughts of attrition (P = 0.80) were also not associated with program rank. CONCLUSIONS: Surgical residents at higher-ranked programs report higher rates of burnout but have similar rates of mistreatment and personal accomplishment. Higher-ranked programs should be particularly vigilant to trainee burnout, and all programs should employ targeted interventions to improve resident well-being. This study highlights the need for greater transparency in reporting objective program-level quality measures pertaining to resident well-being.

RESUMEN

OBJECTIVE: We sought to examine the factors associated with resident perceptions of autonomy and to characterize the relationship between resident autonomy and wellness. BACKGROUND: Concerns exist that resident autonomy is decreasing, impacting competence. METHODS: Quantitative data were collected through a cross-sectional survey administered after the 2020 ABSITE. Qualitative data were collected through interviews and focus groups with residents and faculty at 15 programs. RESULTS: Seven thousand two hundred thirty-three residents (85.5% response rate) from 324 programs completed the survey. Of 5139 residents with complete data, 4424 (82.2%) reported appropriate autonomy, and these residents were less likely to experience burnout [odds ratio (OR) 0.69; 95% CI 0.58-0.83], suicidality (OR 0.69; 95% CI 0.54-0.89), and thoughts of leaving their programs (OR 0.45; 95% CI 0.37-0.54). Women were less likely to report appropriate autonomy (OR 0.81; 95% CI 0.68-0.97). Residents were more likely to report appropriate autonomy if they also reported satisfaction with their workload (OR 1.65; 95% CI 1.28-2.11), work-life balance (OR 2.01; 95% CI 1.57-2.58), faculty engagement (OR 3.55; 95% CI 2.86-4.35), resident camaraderie (OR 2.23; 95% CI, 1.78-2.79), and efficiency and resources (OR 2.37; 95% CI 1.95-2.88). Qualitative data revealed that (1) autonomy gives meaning to the clinical experience of residency, (2) multiple factors create barriers to autonomy, and (3) autonomy is not inherent to the training paradigm, requiring residents to learn behaviors to "earn" it. CONCLUSION: Autonomy is not considered an inherent part of the training paradigm such that residents can assume that they will achieve it. Resources to function autonomously should be allocated equitably to support all residents' educational growth and wellness.

RESUMEN

OBJECTIVE: Racial/ethnic discrimination is one form of mistreatment and a known risk factor for physician burnout. In the present study, we aimed to characterize the forms and identify the sources of racial/ethnic discrimination among vascular surgery trainees. METHODS: We performed a cross-sectional study of U.S. vascular surgery trainees who had voluntarily participated in an anonymous survey administered after the 2021 Vascular Surgery In-Training Examination. The primary outcome measures were self-reported mistreatment and sources of mistreatment between race and ethnicity groups. We used χ2 tests and logistic regression for bivariate and multivariable analyses, respectively. RESULTS: Representing all 123 vascular surgery training programs, 510 trainees (66.9% men) participated in the survey (83.6% response rate). Most of the trainees had self-identified as White (53.1%), followed by Asian (24.4%), Hispanic/Latinx (7.6%), Black (4.2%), and other/prefer not to say (10.8%). No significant differences were found in the self-reported duty hour violations among the groups. Black (56.3%) and Asian (36.3%) trainees reported higher rates of racial/ethnic discrimination compared with the White, Hispanic/Latinx, and other/prefer not to say groups (P < .001). Patients and their families were reported as the most common source (74.7%). Other reported sources of discrimination included nurses or staff (60%), attendings (37.4%), co-residents (31.3%), and administration (16.9%). Regarding specific forms of racial discrimination, Black and Asian trainees reported the highest rates of different standards of evaluation (20% and 5.9%, respectively), being mistaken for a nonphysician (50.0% and 5.9%, respectively), slurs and/or hurtful comments (13.3% and 5.9%, respectively), social isolation (13.0% and 1.0%, respectively), and being mistaken for another trainee of the same race/ethnicity (60.0% and 33.7%, respectively). Only 62.5% of Black trainees reported their program/institution would take their mistreatment report seriously compared with the White (88.9%), Hispanic/Latinx (88.2%), Asian (83.2%), and other/prefer not to say (71.4%) trainees (P = .01). On multivariable analysis, female gender (odds ratio [OR], 2.5; 95% confidence interval [CI], 1.44-4.33), Asian race (OR, 6.9; 95% CI, 3.53-13.3), Black race (OR, 13.6; 95% CI, 4.25-43.4), and training in the Southeastern United States (OR, 3.8; 95% CI, 1.17-12.80) were risk factors for racial/ethnic discrimination. CONCLUSIONS: The results from the survey revealed that racial/ethnic discrimination persists in surgical training programs, with Asian and Black trainees reporting higher rates than other racial and ethnic groups. Overall, patients and family members were the most common source of racial/ethnic discrimination. However, faculty, staff, and co-trainees also contributed to racial/ethnic discrimination. Further interventions that optimize diversity, equity, and inclusion strategies and policies to address all forms of racial/ethnic discrimination with faculty, staff, and patients within the hospital are critically needed.

RESUMEN

OBJECTIVE: Mistreatment among vascular surgery trainees is a known risk factor for physician burnout. This study aims to characterize forms of and identify sources of mistreatment. METHODS: This is a cross-sectional study of United States vascular surgery trainees who voluntarily participated in an anonymous survey administered after the 2021 Vascular Surgery In-Training Examination. The primary outcome measures were self-reported mistreatment and sources of mistreatment between genders. Logistic regression was used for multivariable analysis. RESULTS: Representing all 125 vascular surgery training programs, 510 trainees (66.9% male) participated in the survey (83.6% response rate). Mistreatment was reported by 54.8% of trainees, with twice as many women reporting as men (82.3% vs 41.0%; P < .001). Women reported higher rates of being shouted at (44.1% vs 21.1%; P < .001); repeatedly reminded of errors (24.3% vs 16.1%; P = .04); ignored/treated hostilely (28.9% vs 10.5%; P < .001); subjected to crude/sexually demeaning remarks, stories, jokes (19.2% vs 2.1%; P < .001); evaluated by different standards (29.3% vs 2.1%; P < .001); and mistaken for a non-physician (75.2% vs 3.5%; P < .001). Among trainees reporting bullying, attendings were the most common source (68.5%). Patients and their families were the most common source of sexual harassment (66.7%), gender discrimination (90.4%), and racial discrimination (74.4%). Compared with men, women identified more patients and families as the source of bullying (50.0% vs 29.7%; P = .005), gender discrimination (97.2% vs 50.0%; P < .001), and sexual harassment (78.4% vs 27.3%; P = .003). Compared with men, women more frequently felt unprepared to respond to the behavior in the moment (10.4% vs 4.6%; P = .002), did not know how to report mistreatment at their institution (7.6% vs 3.2%; P = .04), and did not believe that their institution would take their mistreatment report seriously (9.0% vs 3.9%; P = .002). On multivariable analysis, female gender was an independent risk factor for both gender discrimination (odds ratio, 56.62; 95% confidence interval, 27.89-115) and sexual harassment (odds ratio, 26.2; 95% confidence interval, 3.34-14.8) when adjusting for children, training year, relationship status, and training program location. CONCLUSIONS: A majority of vascular surgery trainees experience mistreatment during training. Sources and forms of abuse are varied. Understanding the sources of mistreatment is critical to guide intervention strategies such as faculty remediation and/or sanctions; allyship training for staff, residents, and faculty; and institutional procedures for patient-initiated abuse.

RESUMEN

INTRODUCTION: Patients admitted to intensive care units (ICUs) have high rates of mortality and morbidity. Improved communication between providers within ICUs may reduce morbidity. The goal of this study is to leverage a natural experiment of the temporally staggered implementation of a smart phone application for interprofessional communication to quantify the association with postoperative mortality and morbidity among critically ill surgical patients. METHODS: We conducted an observational case-control study and utilized a difference-in-difference model to determine the impact of temporally staggered implementation of an interprofessional communication smart phone application on mortality, postoperative hyperglycemia, malnutrition, venous thromboembolism (VTE), and surgical site infections. Our study included patients who underwent surgical procedures and were admitted to the ICU at one of three hospitals (one academic medical center, hospital A, and two community hospitals, hospitals B and C) in a single health system between March 2018 and April 2021. RESULTS: Our cohort consisted of 1457 patients, of which 1174 were hospitalized at hospital A and 283 at hospitals B and C. In the full cohort, 80 (5.6%) patients died during ICU admission. Difference-in-difference analysis demonstrated a relative difference in mortality of 4.8% [1.1%-8.5%] (P = 0.04) at hospitals B and C compared to hospital A after the implementation of the application. Our model demonstrated a 2.5% difference in VTEs [1.1%-3.8%], P = 0.03. There were no significant reductions in hyperglycemia, malnutrition, or surgical site infection. CONCLUSIONS: The implementation of an interprofessional communication smart phone application is associated with reduced mortality and VTE incidence among critically ill surgical patients across three diverse hospitals.

RESUMEN

INTRODUCTION: More than 30% of patients experience complications after major gastrointestinal (GI) surgery, many of which occur after discharge when patients and families must assume responsibility for monitoring. Patient-reported outcomes (PROs) have been proposed as a tool for remote monitoring to identify deviations in recovery, and recognize and manage complications earlier. This study's objective was to characterize barriers and facilitators to the use of PROs as a patient monitoring tool following GI surgery. METHODS: We conducted semistructured interviews with GI surgery patients and clinicians (surgeons, nurses, and advanced practitioners). Patients and clinicians were asked to describe their experience using a PRO monitoring system in three surgical oncology clinics. Using a phenomenological approach, research team dyads independently coded the transcripts using an inductively developed codebook and the constant comparative approach with differences reconciled by consensus. RESULTS: Ten patients and five clinicians participated in the interviews. We identified four overarching themes related to functionality, workflow, meaningfulness, and actionability. Functionality refers to barriers faced by clinicians and patients in using the PRO technology. Workflow represents problematic integration of PROs into the clinical workflow and need for setting expectations with patients. Meaningfulness refers to lack of patient and clinician understanding of the impact of PROs on patient care. Finally, actionability reflects barriers to follow-up and practical use of PRO data. CONCLUSIONS: While use of PRO systems for postoperative patient monitoring have expanded, significant barriers persist for both patients and clinicians. Implementation enhancements are needed to optimize functionality, workflow, meaningfulness, and actionability.

RESUMEN

BACKGROUND AND OBJECTIVES: Evidence for neoadjuvant therapy (NAT) in extrahepatic cholangiocarcinoma (eCCA) is limited. Our objectives were to: (1) characterize treatment trends, (2) identify factors associated with receipt of NAT, and (3) evaluate associations between NAT and postoperative outcomes. METHODS: Retrospective cohort study of the National Cancer Database (2004-2017). Multivariable logistic regression assessed associations between NAT and postoperative outcomes. Stratified analysis evaluated differences between surgery first, neoadjuvant chemotherapy, and neoadjuvant chemoradiation (CRT). RESULTS: Among 8040 patients, 417 (5.2%) received NAT. NAT increased during the study period 2.9%-8.4% (p < 0.001). Factors associated with receipt of NAT included age <50 (vs. >75, odds ratio [OR] 4.32, p < 0.001) and stage 3 disease (vs. 1, OR 1.68, p = 0.01). Compared with surgery first, patients who received NAT had higher odds of R0 resection (OR 1.49, p = 0.01) and lower 30-day mortality (OR 0.51, p = 0.04). On stratified analysis, neoadjuvant chemotherapy was not associated with differences in any outcomes. However, neoadjuvant CRT was associated with improvement in R0 resection (OR 3.52, <0.001) and median survival (47.8 vs. 25.3 months, log-rank < 0.001) compared to surgery first. CONCLUSIONS: NAT, particularly neoadjuvant CRT, was associated with improved postoperative outcomes. These data suggest expanding the use of neoadjuvant CRT for eCCA.

RESUMEN

BACKGROUND AND OBJECTIVES: Emergency department (ED) utilization after gastrointestinal cancer operations is poorly characterized. Our study objectives were to determine the incidence of, reasons for, and predictors of ED treat-and-release encounters after gastrointestinal cancer operations. METHODS: Patients who underwent elective esophageal, hepatobiliary, gastric, pancreatic, small intestinal, or colorectal operations for cancer were identified in the 2015-2017 Healthcare Cost and Utilization Project State Inpatient and State Emergency Department Databases for New York, Maryland, and Florida. The primary outcomes were the incidence of ED treat-and-release encounters and readmissions within 30 days of discharge. RESULTS: Among 51 527 patients at 406 hospitals, 4047 (7.9%) had an ED treat-and-release encounter, and 5573 (10.8%) had an ED encounter with readmission. In total, 40.7% of ED encounters were treat-and-release encounters. ED treat-and-release encounters were most frequently for pain (12.0%), device/ostomy complaints (11.7%), or wound complaints (11.4%). ED treat-and-release encounters predictors included non-Hispanic Black race/ethnicity (odds ratio [OR] 1.24, 95% confidence interval [CI] 1.12-1.37) and Medicare (OR 1.27, 95% CI 1.16-1.40) or Medicaid (OR 1.82, 95% CI 1.62-2.40) coverage. CONCLUSIONS: ED treat-and-release encounters are common after major gastrointestinal operations, making up nearly half of postdischarge ED encounters. The reasons for ED treat-and-release encounters differ from those for ED encounters with readmissions.

RESUMEN

STUDY OBJECTIVE: The influence of workplace mistreatment on the well-being and career satisfaction of emergency medicine residents is unknown. This study examined the relationships between burnout, career choice regret, and workplace mistreatment in a national sample of emergency medicine residents. METHODS: This was a secondary analysis of a survey study on the prevalence of workplace mistreatment among emergency residents. Residents who reported emotional exhaustion or depersonalization at least once per week were considered to have burnout. Residents who reported dissatisfaction with their decision to become an emergency physician were considered to have career choice regret. Respondents also reported the type (discrimination, abuse, sexual harassment) and frequency of mistreatment over the academic year. Multivariable logistic regression, adjusting for program characteristics, was used to examine resident characteristics associated with burnout and career choice regret, with the frequency of mistreatment as a covariate. RESULTS: Of the 8,162 eligible residents, 7,680 (94.1 %) participated. About a third of respondents reported burnout (2,188 of 6,902, 31.7%), whereas a minority (224 of 6,923, 3.2%) reported career choice regret. Of the 7,087 responses on mistreatment frequency, 2,117 (29.9%) reported "a few times per year," and 1,296 (18.3%) reported "a few times per month or more." Compared with residents who never experienced mistreatment, residents who reported increasing frequencies of mistreatment were associated with having burnout-from mistreatment a few times per year (OR [odds ratio],1.6; 99% CI [confidence interval], 1.3 to 1.9) to a few times per month or more (OR, 3.3; 99% CI, 2.7 to 4.1). Compared with residents without burnout, residents who reported burnout were associated with having career choice regret (OR, 11.3; 99% CI, 7.0 to 18.1). After adjusting for burnout, there were no significant relationships between the frequency of mistreatment and career choice regret. CONCLUSIONS: Workplace mistreatment is associated with burnout, but not career choice regret, among emergency medicine residents. Efforts to address workplace mistreatment may improve emergency medicine residents' professional well-being.

RESUMEN

BACKGROUND: Cancer-related deaths over the next decade are expected to increase due to cancer screening deficits associated with the coronavirus disease 2019 (COVID-19) pandemic. Although national deficits have been quantified, a structured response to identifying and addressing local deficits has not been widely available. The objectives of this report are to share preliminary data on monthly screening deficits in breast, colorectal, lung, and cervical cancers across diverse settings and to provide online materials from a national quality improvement (QI) study to help other institutions to address local screening deficits. METHODS: This prospective, national QI study on Return-to-Screening enrolled 748 accredited cancer programs in the United States from April through June 2021. Local prepandemic and pandemic monthly screening test volumes (MTVs) were used to calculate the relative percent change in MTV to describe the monthly screening gap. RESULTS: The majority of facilities reported monthly screening deficits (colorectal cancer, 80.6% [n = 104/129]; cervical cancer, 69.0% [n = 20/29]; breast cancer, 55.3% [n = 241/436]; lung cancer, 44.6% [n = 98/220]). Overall, the median relative percent change in MTV ranged from -17.7% for colorectal cancer (interquartile range [IQR], -33.6% to -2.8%), -6.8% for cervical cancer (IQR, -29.4% to 1.7%), -1.6% for breast cancer (IQR, -9.6% to 7.0%), and 1.2% for lung cancer (IQR, -16.9% to 19.0%). Geographic differences were not observed. There were statistically significant differences in the percent change in MTV between institution types for colorectal cancer screening (P = .02). CONCLUSION: Cancer screening is still in need of urgent attention, and the screening resources made available online may help facilities to close critical gaps and address screenings missed in 2020. LAY SUMMARY: Question: How can the effects of the coronavirus disease 2019 pandemic on cancer screening be mitigated? FINDINGS: When national resources were provided, including methods to calculate local screening deficits, 748 cancer programs promptly enrolled in a national Return-to-Screening study, and the majority identified local screening deficits, most notably in colorectal cancer. Using these results, 814 quality improvement projects were initiated with the potential to add 70,000 screening tests in 2021. Meaning: Cancer screening is still in need of urgent attention, and the online resources that we provide may help to close critical screening deficits.

RESUMEN

BACKGROUND: Physicians, particularly trainees and those in surgical subspecialties, are at risk for burnout. Mistreatment (i.e., discrimination, verbal or physical abuse, and sexual harassment) may contribute to burnout and suicidal thoughts. METHODS: A cross-sectional national survey of general surgery residents administered with the 2018 American Board of Surgery In-Training Examination assessed mistreatment, burnout (evaluated with the use of the modified Maslach Burnout Inventory), and suicidal thoughts during the past year. We used multivariable logistic-regression models to assess the association of mistreatment with burnout and suicidal thoughts. The survey asked residents to report their gender. RESULTS: Among 7409 residents (99.3% of the eligible residents) from all 262 surgical residency programs, 31.9% reported discrimination based on their self-identified gender, 16.6% reported racial discrimination, 30.3% reported verbal or physical abuse (or both), and 10.3% reported sexual harassment. Rates of all mistreatment measures were higher among women; 65.1% of the women reported gender discrimination and 19.9% reported sexual harassment. Patients and patients' families were the most frequent sources of gender discrimination (as reported by 43.6% of residents) and racial discrimination (47.4%), whereas attending surgeons were the most frequent sources of sexual harassment (27.2%) and abuse (51.9%). Proportion of residents reporting mistreatment varied considerably among residency programs (e.g., ranging from 0 to 66.7% for verbal abuse). Weekly burnout symptoms were reported by 38.5% of residents, and 4.5% reported having had suicidal thoughts during the past year. Residents who reported exposure to discrimination, abuse, or harassment at least a few times per month were more likely than residents with no reported mistreatment exposures to have symptoms of burnout (odds ratio, 2.94; 95% confidence interval [CI], 2.58 to 3.36) and suicidal thoughts (odds ratio, 3.07; 95% CI, 2.25 to 4.19). Although models that were not adjusted for mistreatment showed that women were more likely than men to report burnout symptoms (42.4% vs. 35.9%; odds ratio, 1.33; 95% CI, 1.20 to 1.48), the difference was no longer evident after the models were adjusted for mistreatment (odds ratio, 0.90; 95% CI, 0.80 to 1.00). CONCLUSIONS: Mistreatment occurs frequently among general surgery residents, especially women, and is associated with burnout and suicidal thoughts.

RESUMEN

BACKGROUND: Substantial resources are dedicated to long-term follow-up within cancer registries; however, the completeness of these data is poorly characterized. Our objectives were to quantify long-term cancer follow-up data completeness and the effort required to collect these data using the National Cancer Database (NCDB). METHODS: To quantify data completeness, patients diagnosed with cancer in 1989 were identified in the NCDB and loss to follow-up rates were assessed for 25 years after diagnosis. To quantify data collection effort, patients diagnosed from 1989 to 2014 who were alive and eligible for follow-up in 2014 were identified and the effort to perform patient follow-up was obtained via a survey of tumor registrars. The effort to perform follow-up beyond various intervals after diagnosis was calculated. RESULTS: In total, 484,201 patients at 958 hospitals were diagnosed with cancer in 1989. After 5 years, 6.5% of patients were lost to follow-up (13.1% of living patients), 50.3% were deceased, and 43.2% had ongoing follow-up. After 15 years, 22.9% were lost to follow-up (68.7% of living patients), 66.7% were deceased, and 10.5% had ongoing follow-up. By 25 years, loss to follow-up increased to 28.6% (93.7% of living patients), 69.5% were deceased, and 1.9% had ongoing follow-up. In 2014, 522,838 h were spent performing follow-up for 2,091,353 patients at 1456 hospitals who were >15 years from their initial cancer diagnosis. CONCLUSIONS: While 5-year follow-up is excellent in the NCDB, loss to follow-up increases over time. The impact of curtailing data collection is under investigation and follow-up duration requirements will be re-evaluated.

RESUMEN

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.

RESUMEN

OBJECTIVE: Burnout and suicidality are known risks for vascular surgeons above other surgical subspecialties, with surgical trainees at risk for exposure to factors that increase burnout. This study aimed to inform initiatives to improve wellness by assessing the prevalence of hazards in vascular training (mistreatment, duty-hour violations) and the rates of wellness outcomes (burnout, thoughts of attrition/specialty change/suicide). We hypothesized that mistreatment and duty-hour violations would predispose trainees to increased burnout. METHODS: We performed a cross-sectional study of residents and fellows enrolled in accredited United States vascular surgery training programs using a voluntary, confidential survey administered during the 2020 Vascular Surgery In-Training Examination. The primary outcome assessed was burnout symptoms reported on a weekly basis or more frequently. The rates of wellness outcomes were measured. The association of mistreatment and duty hours with the primary outcome was modeled with multivariable logistic regression. RESULTS: A total of 475 residents and fellows who were enrolled in one of 120 vascular surgery training programs completed the survey (84.2% response rate). Of 408 trainees completing burnout survey items, 182 (44.6%) reported symptoms of burnout. Fewer trainees reported thoughts of attrition (n = 42 [10.0%], specialty change (n = 35 [8.4%]), or suicide (n = 22 [4.9%]). Mistreatment was reported by 191 vascular trainees (47.3%) and was more common in female trainees (n = 63 [48.5%] reporting monthly or more frequently) compared with male trainees (n = 51 [18.6%]; P < .001). Duty-hour violations were also more commonly reported by female trainees (n = 31 [21.4%] reporting 3+ months in violation) compared with male trainees (n = 50 [16.2%]; P = .002). After controlling for race/ethnicity, postgraduate year, program type, and geography, female trainees were less likely to report burnout (odds ratio [OR], 0.49; 95% confidence interval [CI], 0.28-0.86). Trainees experiencing mistreatment monthly or more were three times more likely to report burnout (OR, 3.09; 95% CI, 1.78-5.39). Frequency of duty-hour violations also increased the odds of reporting burnout (1-2 months in violation: OR, 2.09; 95% CI, 1.17-3.73; 3+ months in violation: OR, 3.95; 95% CI, 2.24-6.97). CONCLUSIONS: Nearly one-half of vascular surgery trainees reported symptoms of burnout, which was associated with frequency of mistreatment and duty-hour violations. Interventions to improve well-being in vascular surgery must be tailored to the local training environment to address trainee experiences that contribute to burnout.

RESUMEN

BACKGROUND: Surgical site infection reduction bundles are effective but can be complex and resource intensive. Understanding which bundle elements are associated with reduced surgical site infections may guide concise bundle implementation. OBJECTIVE: The purpose of this study was to evaluate the association of individual surgical site infection reduction bundle elements with infection rates. DESIGN: This was a post-hoc analysis of a prospective cohort study. SETTING: This study took place at Illinois Surgical Quality Improvement Collaborative hospitals. PATIENTS: Patients who had elective colorectal resections at participating hospitals from 2016 to 2017. INTERVENTIONS: The intervention was a 16-element colorectal surgical site infection reduction bundle. MAIN OUTCOME MEASURES: Surgical site infection rates were compared among patients by adherence with each bundle element using χ 2 tests and multivariable logistic regression. Principal component analysis identified composites of correlated bundle elements. Coincidence analysis identified combinations of bundle elements or principal component composites associated with the absence of surgical site infection. RESULTS: Among 2722 patients, 192 (7.1%) developed a surgical site infection. Infections were less likely when oral antibiotics (OR 0.63 [95% CI 0.41-0.97]), wound protectors (OR 0.55 [95% CI 0.37-0.81]), and occlusive dressings (OR 0.71 [95% CI 0.51-1.00]) were used. Bundle elements were reduced into 5 principal component composites. Adherence with the combination of oral antibiotics, wound protector, or redosing intravenous antibiotic prophylaxis plus chlorhexidine-alcohol intraoperative skin preparation was associated with the absence of infection (consistency = 0.94, coverage = 0.96). Four of the 5 principal component composites in various combinations were associated with the absence of surgical site infection, whereas the composite consisting of occlusive dressing placement, postoperative dressing removal, and daily postoperative chlorhexidine incisional cleansing had no association with the outcome. LIMITATIONS: The inclusion of hospitals engaged in quality improvement initiatives may limit the generalizability of these data. CONCLUSION: Bundle elements had varying association with infection reduction. Implementation of colorectal surgical site infection reduction bundles should focus on the specific elements associated with low surgical site infections.

DESEMPAQUETANDO PAQUETES EVALUACIN DE LA ASOCIACIN DE ELEMENTOS INDIVIDUALES DEL PAQUETE DE REDUCCIN DE INFECCIONES DEL SITIO QUIRRGICO COLORRECTAL CON LAS TASAS DE INFECCIN EN UNA COLABORACIN ESTATAL: ANTECEDENTES:Los paquetes de reducción de infecciones del sitio quirúrgico son efectivos pero pueden ser complejos y requieren muchos recursos. Comprender qué elementos del paquete están asociados con la reducción de las infecciones del sitio quirúrgico puede guiar la implementación concisa del paquete.OBJETIVO:Evaluar la asociación de los elementos individuales del paquete de reducción de infecciones del sitio quirúrgico con las tasas de infección.DISEÑO:Análisis post-hoc de un estudio de cohorte prospectivo.ESCENARIO:Hospitales colaborativos para la mejora de la calidad quirúrgica de Illinois.PACIENTES:Resecciones colorrectales electivas en los hospitales participantes entre 2016 y 2017.INTERVENCIONES:Paquete de reducción de infección del sitio quirúrgico colorrectal de 16 elementos.PRINCIPALES MEDIDAS DE RESULTADO:Se compararon las tasas de infección del sitio quirúrgico entre los pacientes según la adherencia con cada elemento del paquete mediante pruebas de Chi cuadrado y regresión logística multivariable. El análisis de componentes principales identificó compuestos de elementos de paquete correlacionados. El análisis de coincidencia identificó combinaciones de elementos del haz o compuestos de componentes principales asociados con la ausencia de infección del sitio quirúrgico.RESULTADOS:Entre 2722 pacientes, 192 (7,1%) desarrollaron una infección del sitio quirúrgico. Las infecciones fueron menos probables cuando se administraron antibióticos orales (OR 0,63 (IC 95% 0,41-0,97)), protectores de heridas (OR 0,55 (IC 95% 0,37-0,81)) y vendajes oclusivos (OR 0.71 (IC 95% 0,51-1,00]) fueron usados. Los elementos del paquete se redujeron a 5 grupos de componentes principales. La adherencia a la combinación de (1) antibióticos orales, (2) protector de heridas o (3) redosificación de profilaxis antibiótica intravenosa más preparación de la piel intraoperatoria con clorhexidina-alcohol se asoció con la ausencia de infección (consistencia = 0,94, cobertura = 0,96). Cuatro de los cinco grupos de componentes principales en varias combinaciones se asociaron con la ausencia de infección del sitio quirúrgico, mientras que el grupo que consiste en la colocación del apósito oclusivo, la remosión del apósito en posoperatorio y la limpieza incisional posoperatoria diaria con clorhexidina no tuvo asociación con el resultado.LIMITACIONES:La inclusión de hospitales que participan en iniciativas de mejora de la calidad puede limitar la generalización de estos datos.CONCLUSIONES:Los elementos del paquete tuvieron una asociación variable con la reducción de la infección. La implementación de paquetes de reducción de infecciones del sitio quirúrgico colorrectal debe centrarse en los elementos específicos asociados con pocas infecciones del sitio quirúrgico.

RESUMEN

INTRODUCTION: Many surgical societies have recently resumed in-person meetings after canceling or adopting virtual formats during the COVID-19 pandemic. These meetings implemented safety measures to limit viral exposure and ensure participant safety. While there have been anecdotal reports of COVID-19 cases after attendance, no large-scale assessments have been undertaken. The objective of this study was to evaluate COVID-19 positivity following an in-person surgical society meeting. METHODS: An online survey was administered to participants of the Society for Asian Academic Surgeons annual meeting, which was held in Chicago, Illinois in September 2021. This survey assessed vaccination status, in-person versus virtual conference attendance, and COVID-19 testing and symptoms in the 7 d immediately following the meeting. RESULTS: Among the 220 meeting participants, 173 attended in person (79%). There were 91 survey respondents (41% response rate): 67% attending physicians, 27% trainees, and 6% medical students. Nearly, all (99%) reported being fully vaccinated against COVID-19. COVID-19 testing was sought within 7 d of the meeting by 15% of in-person respondents, and all reported negative results. Among individuals who were not tested, no one reported development of symptoms (cough, shortness of breath, fever, new loss of taste/smell, etc.). CONCLUSIONS: Among in-person attendees of a recent surgical society meeting, no one reported positive COVID-19 testing after the meeting, and individuals who were not tested denied developing symptoms. While these results are encouraging, societies hosting meetings should continue to proactively assess the safety of in-person meetings to promptly identify outbreaks and opportunities for improvement.

RESUMEN

INTRODUCTION: While complication rates have been well described using the National Surgical Quality Improvement Program (NSQIP) and National Surgical Quality Improvement Program-Pediatric registries, there have been no direct comparisons of outcomes between adults and children. Our objective was to describe differences in postoperative outcomes between children and adults undergoing common surgical procedures. METHODS: Using data from 2013 to 2017, we identified patients undergoing laparoscopic appendectomy, laparoscopic cholecystectomy, thyroidectomy, and colectomy. Propensity score matching on gender, race, American Society of Anesthesiologists class, surgical indication, and procedure type was performed. Outcomes included surgical site infection (SSI), readmission rates, mortality/serious morbidity, and hospital length of stay and were analyzed using χ2 and student's t-test with statistical significance defined as P < 0.05. RESULTS: We matched 79,866 patients from 812 hospitals. Compared to adults, children had higher rates of SSI following appendectomy (4.12% versus 1.40%, P < 0.01) and cholecystectomy (0.96% versus 0.66%, P = 0.04), readmission following appendectomy (4.26% versus 2.47%, P < 0.01), and longer length of stay in all procedures. In adults, 30-day mortality/serious morbidity was higher for all procedures. CONCLUSIONS: Compared to adults, children demonstrate unique surgical complication and outcome profiles. Quality improvement efforts such as SSI prevention bundles and enhanced recovery protocols used in adults should be expanded to children.
