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.

Racial and Ethnic Disparities in Operative Experience Among General Surgery Residents: A Multi-Institutional Study from the US ROPE Consortium.

OBJECTIVE: To determine the relationship between race/ethnicity and case volume among graduating surgical residents. BACKGROUND: Racial/ethnic minority individuals face barriers to entry and advancement in surgery; however, no large-scale investigations of the operative experience of racial/ethnic minority residents have been performed. METHODS: A multi-institutional retrospective analysis of the Accreditation Council for Graduate Medical Education case logs of categorical general surgery residents at 20 programs in the US Resident OPerative Experience Consortium database was performed. All residents graduating between 2010 and 2020 were included. The total, surgeon chief, surgeon junior, and teaching assistant case volumes were compared between racial/ethnic groups. RESULTS: The cohort included 1343 residents. There were 211 (15.7%) Asian, 65 (4.8%) Black, 73 (5.4%) Hispanic, 71 (5.3%) "Other" (Native American or Multiple Race), and 923 (68.7%) White residents. On adjusted analysis, Black residents performed 76 fewer total cases (95% CI, -109 to -43, P <0.001) and 69 fewer surgeon junior cases (-98 to -40, P <0.001) than White residents. Comparing adjusted total case volume by graduation year, both Black residents and White residents performed more cases over time; however, there was no difference in the rates of annual increase (10 versus 12 cases per year increase, respectively, P =0.769). Thus, differences in total case volume persisted over the study period. CONCLUSIONS: In this multi-institutional study, Black residents graduated with lower case volume than non-minority residents throughout the previous decade. Reduced operative learning opportunities may negatively impact professional advancement. Systemic interventions are needed to promote equitable operative experience and positive culture change.

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.

A multi-institutional study from the US ROPE consortium examining factors associated with endocrine surgery exposure for general surgery residents.

BACKGROUND: Prior analyses of general surgery resident case logs have indicated a decline in the number of endocrine procedures performed during residency. This study aimed to identify factors contributing to the endocrine operative experience of general surgery residents and compare those who matched in endocrine surgery fellowship with those who did not. METHODS: We analyzed the case log data of graduates from 18 general surgery residency programs in the US Resident Operative Experience Consortium over an 11-year period. RESULTS: Of the 1,240 residents we included, 17 (1%) matched into endocrine surgery fellowships. Those who matched treated more total endocrine cases, including more thyroid, parathyroid, and adrenal cases, than those who did not (81 vs 37, respectively, P < .01). Program-level factors associated with increased endocrine volume included endocrine-specific rotations (+10, confidence interval 8-12, P < .01), endocrine-trained faculty (+8, confidence interval 7-10, P < .01), and program co-location with otolaryngology residency (+5, confidence interval 2 -8, P < .01) or endocrine surgery fellowship (+4, confidence interval 2-6, P < .01). Factors associated with decreased endocrine volume included bottom 50th percentile in National Institute of Health funding (-10, confidence interval -12 to -8, P < .01) and endocrine-focused otolaryngologists (-3, confidence interval -4 to -1, P < .01). CONCLUSION: Several characteristics are associated with a robust endocrine experience and pursuit of an endocrine surgery fellowship. Modifiable factors include optimizing the recruitment of dedicated endocrine surgeons and the inclusion of endocrine surgery rotations in general surgery residency.

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.

Examining the transplant case composition of early-career transplant surgeons.

Fellowship training established by the American Society of Transplant Surgeons and certified by the Transplant Accreditation and Certification Council provides trainees with broad exposure and practice readiness for the core aspects of abdominal transplantation. However, the operative case mix of a new transplant surgeon early in practice is unknown. This study examined the volume and composition of the transplant case mix of early-career transplant surgeons to better inform residents interested in transplantation about potential career opportunities following fellowship. cas 209 early-career transplant surgeons were identified from the UNOS database containing encrypted surgeon-specific identifiers and were included in this study. At 5 years into practice, there were 85 (40.7%) kidney-predominant, 38 (18.2%) liver-predominant, and 86 (41.1%) multiorgan transplant surgeons. Comparing surgeon subgroups, multiorgan surgeons performed more transplants in year 5 of practice than both liver-predominant and kidney-predominant surgeons (both p < .05). This is the first study to describe the transplant case composition of the early-career transplant surgeons. This data can be used to inform aspiring transplant surgeons about potential career opportunities and to assist fellowship programs in guiding and mentoring fellows.

Biophysiological stress and sleep deprivation among abdominal transplant surgery fellows: A prospective multi-institutional study using a wearable device.

BACKGROUND: Transplant surgery fellowship is physically and emotionally demanding. The objective of this study was to characterize biophysiological stress and sleep patterns among transplant surgery fellows. METHODS: Participating fellows wore a biophysical monitor over a 28-day period and completed biweekly surveys. Sleep patterns were dichotomized as normal or sleep deprived, and heart rate variability (HRV) was used to assess stress. RESULTS: Seventeen fellows participated. Fellows were frequently sleep deprived (43.9% of nights) and stress was near universal (87.2% of days). Burnout was reported by 2 fellows (11.8%). Only 4 fellows (23.5%) reported compliance with the Transplant Accreditation and Certification Council managed time policy; these fellows experienced fewer days of stress than non-compliant fellows (79.8% vs 89.2% p = 0.02). CONCLUSIONS: This is the first study to quantify sleep deprivation and stress among transplant fellows. Future work is needed to evaluate the effects of sleep deprivation, and stress on burnout and patient outcomes.

Experience of surgical subspecialty residents on general surgery rotations.

BACKGROUND: Surgical subspecialty residents complete 5-6 years of training which includes general surgery rotations. A lack of data exists evaluating these rotations. This study aims to identify discrepancies in subspecialty training and improve the quality of surgical education. METHODS: Case logs for surgical subspecialty residents and general surgery residents at our institution were analyzed and queried for cases performed on general surgery rotations. A survey was distributed to subspecialty residents regarding their perceptions of these rotations. RESULTS: 50 residents were included in the study and the majority were male (n = 27, 54%). Subspecialty residents perform fewer cases per month compared to general surgery residents (13 vs 21, p < 0.001). 75% of subspecialty residents were satisfied with their experience on general surgery rotations. CONCLUSIONS: Subspecialty residents perform fewer operations on general surgery rotations. Despite this, most are satisfied with off-service rotations and believe they are an important part of their education.

10 Year Analysis of Pediatric Surgery Fellowship Match and Operative Experience: Concerning Trends?

OBJECTIVE: This paper aims to evaluate the pediatric surgery training pipeline vis-à-vis the pediatric surgery match and operative experience of pediatric surgery fellows. SUMMARY OF BACKGROUND DATA: Pediatric surgery remains a competitive surgical subspecialty. However, there is concern that operative experience for pediatric surgery fellows is changing. This paper examines the selectivity of the pediatric surgery match, along with the operative experience of pediatric surgery fellows to characterize the state of pediatric surgery training. METHODS: The pediatric surgery fellowship match was analyzed from the National Resident Matching Program data from 2010 to 2019. Selectivity among fellowships was compared using analysis of variance with Dunnett test. Operative log data for pediatric fellows was analyzed using the Accreditation Council for Graduate Medical Education case logs from 2009 to 2019. Linear regression analysis was used to evaluate trends in operative volume over time. RESULTS: Pediatric surgery had the highest proportion of unmatched applicants (47.2% ± 5.3%) and lowest proportion of unfilled positions (1.4% ± 1.6%) when compared to other National Resident Matching Program surgical fellowships. Accreditation Council for Graduate Medical Education case log analysis revealed a statistically significant decrease in cases for graduating fellows (-5.3 cases/year, P < 0.05). Total index cases decreased (-4.7 cases/year, P < 0.01, R 2 = 0.83) such that graduates in 2019 completed 59 fewer index operations than graduates in 2009. CONCLUSION: Although pediatric surgery fellowship remains highly selective there has been a decline in the operative experience for graduating fellows. This highlights the need for evaluation of training paradigms and operative exposure in pediatric surgery to ensure the training of competent pediatric surgeons.

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.

Incidence of attrition among early-career abdominal transplant surgeons.

BACKGROUND: The prevalence of burnout and depression among abdominal transplant surgeons has been well described. However, the incidence of early-career transplant surgeons leaving the field is unknown. The objective of this study was to quantify the incidence of attrition among early-career abdominal transplant surgeons. METHODS: A custom database from the Organ Procurement and Transplantation Network with encrypted surgeon-specific identifiers was queried for transplant surgeons who entered the field between 2008 and 2019. Surgeons who experienced attrition, defined as not completing a subsequent transplant after a minimum of 5, were identified. Surgeon-specific case volumes, case mix, and recipient outcomes were modeled to describe their association with attrition. RESULTS: Between 2008 and 2018, 496 abdominal transplant surgeons entered the field and performed 76,465 transplant procedures. A total of 24.4% (n = 121) experienced attrition, with a median time to attrition of 2.75 years. Attrition surgeons completed fewer kidney (7 vs 21, P < .01), pancreas (0.52 vs 1.43, P < .01), and liver transplants (1 vs 4, P < .01) in their first year of practice. Attrition surgeons completed a smaller proportion of their transplant center's volume (9% vs 18%, P < .01) and were less likely to participate in pediatric transplants (26.5% vs 52.5%, P < .01) and living donor kidney transplants (64.5% vs 84.5%, P < .01). On multivariable analysis, performing fewer kidney (odds ratio: 0.98, 95% confidence interval: 0.98-0.99) and liver transplants (odds ratio: 0.98, 95% confidence interval: 0.97-0.98) by year 5 and completing a smaller proportion of their centers' volume (odds ratio: 0.96, 95% confidence interval: 0.94-0.98) were associated with attrition. Furthermore, attrition surgeons had worse allograft and patient survival for liver transplant recipients (both log-rank P < .01). CONCLUSION: This investigation was the first to quantify the high incidence of attrition experienced by early-career abdominal transplant surgeons and its association with surgeon-specific case volumes, case mix, and worse recipient outcomes. These findings suggested the abdominal transplant workforce is struggling to retain their fellowship-trained surgeons.

Do General Surgery Residents Begin Specializing Before Fellowship? A Multi-Institutional Study from the US ROPE Consortium.

BACKGROUND: Single-center data suggest that general surgery residents perform more cases related to their future fellowship compared with their peers. This study aimed to determine whether this experience was true for residents across multiple programs. STUDY DESIGN: Data from graduates of 18 Accreditation Council for Graduate Medical Education (ACGME)-accredited general surgery residency programs in the US Resident OPerative Experience (ROPE) Consortium were analyzed. Residents were categorized as entering 1 of 12 fellowships or entering directly into general surgery practice. Case log operative domains were mapped to each fellowship, and analyses were performed between groups. RESULTS: Of 1,192 graduated general surgery residents, 955 (80%) pursued fellowship training whereas 235 (20%) went directly into general surgery practice. The top 3 fellowships pursued were trauma/surgical critical care (18%), vascular surgery (13%), and minimally invasive surgery (12%). Residents entering minimally invasive surgery performed the most total cases, whereas residents pursuing breast performed the least (1,209 [1,056-1,325] vs 1,091 [1,006-1,171], p < 0.01). For each fellowship type, graduates completed more total fellowship-specific cases in their future specialty compared with their peers (all p < 0.05). This association was observed for all 12 fellowships at the surgeon chief level (all p < 0.05) and for 10 of 12 fellowships at the surgeon junior level (all p < 0.05). CONCLUSIONS: General surgery residents perform more cases related to their future specialty choice compared with their peers. These data suggest that the specialization process begins during residency. This tendency among residents should be considered as general surgery residency undergoes structural redesign in the future.

A multi-institutional study from the US ROPE Consortium examining factors associated with directly entering practice upon residency graduation.

BACKGROUND: There is concern regarding the competency of today's general surgery graduates as a large proportion defer independent practice in favor of additional fellowship training. Little is known about the graduates who directly enter general surgery practice and if their operative experiences during residency differ from graduates who pursue fellowship. METHODS: Nineteen Accreditation Council for Graduate Medical Education-accredited general surgery programs from the US Resident OPerative Experience Consortium were included. Demographics, career choice, and case logs from graduates between 2010 to 2020 were analyzed. RESULTS: There were 1,264 general surgery residents who graduated over the 11-year period. A total of 248 (19.6%) went directly into practice and 1,016 (80.4%) pursued fellowship. Graduates directly entering practice were more likely to be a high-volume resident (43.1% vs 30.5%, P < .01) and graduate from a high-volume program (49.2% vs 33.0%, P < .01). Direct-to-practice graduates performed 53 more cases compared with fellowship-bound graduates (1,203 vs 1,150, P < .01). On multivariable analysis, entering directly into practice was positively associated with total surgeon chief case volume (odds ratio = 1.47, 95% confidence interval 1.18-1.84, P < .01) and graduating from a US medical school (odds ratio = 2.54, 95% confidence interval 1.45-4.44, P < .01) while negatively associated with completing a dedicated research experience (odds ratio = 0.31, 95% confidence interval 0.22-0.45, P < .01). CONCLUSION: This is the first multi-institutional study exploring resident operative experience and career choice. These data suggest residents who desire immediate practice can tailor their experience with less research time and increased operative volume. These data may be helpful for programs when designing their experience for residents with different career goals.

Contemporary Practice of General Surgery in the US: Analysis of American Board of Surgery Diplomate Case Logs.

BACKGROUND: The demographics and operative experience of general surgeons certified by the American Board of Surgery were last examined a decade ago. This study examines the contemporary workforce and scope of practice of general surgeons. STUDY DESIGN: Applications of diplomates seeking American Board of Surgery recertification from 2013 to 2017 were reviewed. Demographic data and case logs from the year before submission were analyzed. Total operative volume was examined, as were total volumes for 13 operative domains and 11 abdominal and alimentary tract subdomains. RESULTS: There were 4,735 general surgeons certified by the American Board of Surgery with a mean ± SD age of 53 ± 8 years and included 19% women and 14% international graduates. Regions of practice were 22% Northeast, 31% Southeast, 20% Midwest, 20% West, and 7% Southwest. Practice settings were 86% urban, 9% large rural, 4% small rural, and 1% isolated. Forty-one percent were 10 years, 35% were 20 years, and 24% were 30 years since initial certification. On average, general surgeons performed 417 ± 338 procedures per year, with abdominal, alimentary tract, and endoscopy being the most common. On multivariable analysis, male sex and being midcareer or late career were positively associated with being a high-volume (top quartile) surgeon, whereas age and practicing in either the Northeast or West demonstrated a negative association. CONCLUSIONS: The demographics of general surgeons have remained stable over time, except for an increased proportion of female surgeons. The overall operative experience is similar to years past but is widely variable between surgeons. Periodic analysis of these data is important for education and certification purposes.

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.

Impact of Integrated Thoracic Residency on General Surgery Residents' Thoracic Operative Volume.

BACKGROUND: Integrated thoracic surgery (I-6) programs have become popular over traditional general surgery (GS) pathways since their inception in 2007. However the effect of I-6 programs on GS resident training remains unknown. The purpose of this study was to evaluate the effect of I-6 programs on the thoracic operative experience of co-located GS residents. METHODS: Thoracic surgery cases recorded by residents in GS programs co-located with I-6 programs until 2019 were analyzed. Cases were reviewed 5 years before (TSR-5) through 5 years after (TSR-5) the matriculation of the first thoracic resident in the co-located I-6 program. To contextualize the overall trends in the field Accreditation Council for Graduate Medical Education GS resident case logs from 1990 to 2018 were analyzed and total thoracic surgery cases recorded. Statistical analysis was performed with linear regression. RESULTS: Residents in 19 GS programs with co-located I-6 programs showed an increase in total thoracic cases from 3710 to 4451 (Δ/year of +85.05 cases a year; P = .03) balanced by an increase in GS residents from 107 to 126 (Δ/year of +1.45; P = .01) with no significant overall change in the median thoracic operative case volume (31.00 at both thoracic residency before and after 5 years). Nationally from 1990 to 2018 there was no change in the total thoracic operative experience for GS graduates. CONCLUSIONS: The introduction of I-6 programs did not negatively impact thoracic operative experience for residents in co-located GS programs. Adequate training of both I-6 and GS residents at the same institution is feasible.

Who is Committed to Education? An Analysis of Surgical Education Research Publications.

OBJECTIVE: Advances in surgical training have led to the recent emergence of surgical education research. While the importance of surgical education research is well recognized, not all surgical journals are publishing these works. The objective of this study was to analyze the volume and types of surgical education publications in general surgery and surgical subspecialty journals. DESIGN: A PubMed search string was developed to identify surgical education publications in general surgery (GS, n = 10) and surgical subspecialty (SS, n = 16) journals from 2015 to 2019. Publications were catalogued into 7 categories: curriculum and/or teaching, trainee assessment, program evaluation, wellness and/or burnout, resident research, case outcomes with resident involvement, and other. Journals were also categorized by impact factor into 3 groups. Statistical analysis was performed using linear regression and Wilcoxon rank-sum to analyze differences in education publication number and percent between GS and SS journals, as well as between different impact factor groups. RESULTS: The median proportion of surgical education publications was 1.2% (IQR 0.3-2.8%) of total publications for journals queried. The highest proportion of surgical education publications by a journal was 13.9%. All other journals had median ≤ 5.5%. GS journals had a significantly higher median percent of surgical education publications than SS journals (2.9% [IQR 1.7-4.8%] vs 0.5% [IQR 0.0-1.4%] p < 0.01). Additionally, no significant differences were found for number of surgical education publications when journals were categorized by IF (p > 0.05). CONCLUSIONS: Education research is an important component of the surgical literature, with similar publication rates among journals of different impact factors. Publication volume is higher among general surgery than surgical subspecialty journals. With the ever-changing paradigm of surgical training, a rigorous scientific approach is needed to ensure effective training of future surgeons. Subspecialty journals should promote surgical education research to further understand and develop training in their field.

Patient personalized translational tools in cystic fibrosis to transform data from bench to bed-side and back.

Cystic fibrosis is a deadly multiorgan disorder caused by loss of function mutations in the gene that encodes for the cystic fibrosis transmembrane conductance regulator (CFTR) chloride/bicarbonate ion channel. More than 1,700 CFTR genetic variants exist that can cause CF, and majority of these are extremely rare. Because of genetic and environmental influences, CF patients exhibit large phenotypic variation. These factors make clinical trials difficult and largely impractical due to limited and heterogeneous patient pools. Also, the benefit of approved small-molecule CF modulators in a large number of rare mutation patients remains unknown. The goal of this study is to perform a comprehensive bench-side study using in vitro patient enteroids and in vivo mice implanted human intestinal organoids (HIOs) to test CF modulator-Ivacaftor response for a rare CF mutation patient. Based on the positive Ivacaftor response in the enteroids, the patient was enrolled in a (N = 1) clinical trial and showed improved clinical outcomes upon Ivacaftor treatment. HIO implantation model allowed in vivo modulator dosing and provided an elegant human organ-based demonstration of bench-to-bedside testing of modulator effects. Additionally, using the CF HIO model the role of CFTR function in the maturation of human intestine was reported for the first time. In all, we demonstrate that these models effectively serve to translate data from the lab to the clinic and back so that patient-specific therapies could be easily identified and disease-relevant developmental abnormalities in CF organs could be studied and addressed.NEW & NOTEWORTHY In this study, we report an example of laboratory models informing clinical care for rare CF mutation patient, with subsequent recapitulation of clinical benefit in a unique and disease relevant, human-derived in vivo model, effectively translating data from the lab to the clinic and back. This extensive work outlines a potential platform to identify patient-specific therapies and to understand relevant developmental abnormalities associated with CF disease.

Transplant Surgery Pipeline: A Report from the American Society of Transplant Surgeons Pipeline Taskforce.

BACKGROUND: Transplant surgery fellowship has evolved over the years and today there are 66 accredited training programs in the US and Canada. There is growing concern, however, about the number of US-trained general surgery residents pursuing transplant surgery. In this study, we examined the transplant surgery pipeline, comparing it with other surgical subspecialty fellowships, and characterized the resident transplantation experience. METHODS: Datasets were compiled and analyzed from surgical fellowship match data obtained from the National Resident Matching Program and ACGME reports and relative fellowship competitiveness was assessed. The surgical resident training experience in transplantation was evaluated. RESULTS: From 2006 to 2018, a total of 1,094 applicants have applied for 946 transplant surgery fellowship positions; 299 (27.3%) were US graduates. During this period, there was a 0.8% decrease per year in US-trained surgical residents matching into transplant surgery (p = 0.042). In addition, transplant surgery was one of the least competitive fellowships compared with other National Resident Matching Program surgical subspeciality fellowships, as measured by the number of US applicants per available fellowship position, average number of fellowship programs listed on each applicant's rank list, and proportion of unfilled fellowship positions (each, p < 0.05). Finally, from 2015 to 2017, there were 57 general surgery residency programs that produced 77 transplant surgery fellows, but nearly one-half of the fellows (n = 36 [46.8%]) came from 16 (28.1%) programs. CONCLUSIONS: Transplant surgery is one of the least competitive and sought after surgical fellowships for US-trained residents. These findings highlight the need for dedicated efforts to increase exposure, mentorship, and interest in transplantation to recruit strong US graduates.
