ABSTRACT

This Open Forum is relevant for investigators who conduct research with historically understudied and marginalized populations. The authors introduce a U.S. Department of Veterans Affairs clinical trial that experienced challenges with recruitment of African American or Black veterans and was terminated for not achieving its recruitment goals. The role of power dynamics in clinical research is discussed, specifically how unequal distributions of power may create recruitment challenges. The authors summarize three lessons learned and offer recommendations for sharing power equitably between investigators and potential participants. By recounting these experiences, the authors seek to promote culturally sensitive, veteran-centered approaches to recruitment in future clinical trials.

ABSTRACT

OBJECTIVE: To evaluate the impact of an innovative leadership development initiative in the core surgery clerkship that addressed duty hours compliance and time-off requests. DESIGN: A combination of deductive and inductive analysis of medical student reflections written after rotating on Acute Care Surgery over 2 academic years (2019-2020 and 2020-2021) was performed. Reflections were part of criteria to receive honors and a prompt was given to discuss their experience in creating their own call schedules. We utilized a combined deductive and inductive process to identify predominant themes within the reflections. Once established, we quantitatively identified frequency and density of themes cited, along with qualitative analysis to determine barriers and lessons learned. SETTING: Dell Seton Medical Center, Dell Medical School at The University of Texas at Austin, a tertiary academic facility. PARTICIPANTS: There were 96 students who rotated on Acute Care Surgery during the study period, 64 (66.7%) of whom completed the reflection piece. RESULTS: We identified 10 predominant themes through the combined deductive and inductive processes. Barriers were cited by most students (n = 58, 91%), with communication being the most commonly discussed theme when cited with a mean 1.96 references per student. Learned leadership skills included: communication, independence, teamwork, negotiating skills, reflection of best practices by residents, and realizing the importance of duty hours. CONCLUSIONS: Transferring duty hour scheduling responsibilities to medical students resulted in multiple professional development opportunities while decreasing administrative burden and improving adherence to duty hour requirements. This approach requires further validation, but may be considered at other institutions seeking to improve the leadership and communication skills of its students, while improving adherence to duty hour restrictions.

ABSTRACT

INTRODUCTION: The COVID-19 pandemic has significantly impacted the diagnosis of breast cancer (BC). With a large Hispanic/Latinx population, early revocation of mask mandates, and lower vaccination rate than many other states, this study explores the relationship between COVID-19 and the presentation and diagnosis of BC patients in the unique socio-politico-economic context of Central Texas. METHODS: This study is a retrospective review of the Seton Medical Center Austin tumor registry for BC patients from March 1, 2019 to March 2, 2021. We compared demographics, insurance status, clinical and pathologic stage, and time from diagnosis to intervention between "pre-COVID" (March 1, 2019- March 1, 2020) and "post-COVID" (March 2, 2020-March 2, 2021). We utilized descriptive, univariate, and multivariable logistic regression statistics. RESULTS: There were 781 patients diagnosed with BC, with 113 fewer post-COVID compared to pre-COVID. The proportion of Black patients diagnosed with BC decreased post-COVID compared with pre-COVID (10.1%-4.5%, P = 0.002). When adjusting for other factors, uninsured and underinsured patients had increased odds of presenting with late-stage BC (odds ratio:5.40, P < 0.001). There was also an association between presenting with stage 2 or greater BC and delayed time-to-intervention. CONCLUSIONS: Although fewer women overall were diagnosed with BC post-COVID, the return to baseline diagnoses has yet to be seen. We identified a pandemic-related decrease in BC diagnoses in Black women and increased odds of late-stage cancer among uninsured patients, suggesting a disparate relationship between COVID-19 and health care access and affordability. Outreach and screening efforts should address strategies to engage Black and uninsured patients.

ABSTRACT

Purpose: There are various assessments used during the core surgical clerkship (CSC), each of which may be influenced by factors external to the CSC or have inherent biases from an equity lens. In particular, the National Board of Medical Examiners' Clinical Subject Exams ("Shelf") is used heavily and may not reflect clerkship curriculum or clinical learning. Methods: This is a retrospective review of medical student characteristics and assessments during the CSC from July 2017-June 2021. Assessment methods included: subjective Clinical Performance Assessments (CPA), Shelf, Objective Structured Clinical Examinations, and a short-answer in-house examination (IHE) culminating in a Final Grade (FG) of Honors/Pass/Fail. A Shelf score threshold for Honors was added in academic years 2020-2021. Descriptive, univariate, and multivariable logistic and linear regression statistics were utilized. Results: We reviewed records of 192 students. Of these, 107 (55.7%) were female, median age was 24 [IQR: 23-26] years, and most were White/Caucasian (N = 106, 55.2%). Univariate analysis showed the number of Exceeds Expectations obtained on CPA to be influenced by surgical subspecialty taken (p = 0.013) and academic year (p < 0.001). Shelf was influenced by students' race (p = 0.009), timing of CSC before or after Internal Medicine (67.9 ± 7.3 vs 72.9 ± 7.1, p < 0.001), and Term taken (increasing from 66.0 ± 8.7 to 73.4 ± 7.5, p < 0.001). IHE scores did not have any external associations. After adjustment with multivariable logistic and linear regressions, CPA and IHE did not have external associations, but higher scores were obtained on Shelf exam in Terms 3, 5, and 6 (by 4.62 [95% CI 0.86-8.37], 4.92 [95% CI 0.53-9.31], and 7.56 [95% CI 2.81-12.31] points, respectively. Odds of FG honors were lower when Shelf threshold was implemented (OR 0.17 [95% CI 0.06-0.50]), and increased as students got older (OR 1.14 [95% CI 1.01-1.30]) or on specific subspecialties, such as vascular surgery (OR 7.06 [95% CI 1.21-41.26]). Conclusions: The Shelf is substantially influenced by temporal associations across Terms and timing in relation to other clerkships, such as Internal Medicine. An IHE reflective of a clerkship's specified curriculum may be a more equitable summative assessment of the learning that occurs from the CSC curriculum, with fewer biases or influences external to the CSC.

ABSTRACT

OBJECTIVE: Examine the concordance of perceived operative autonomy between attendings and resident trainees. DESIGN: Faculty and trainees rated trainee operative autonomy using the 4-level Zwisch scale over a variety of cases and training years. The respective ratings were then compared to explore the effects of experience, gender, case complexity, trainee, trainer, and other covariates to perceived autonomy. SETTING: This study was conducted over 14 general surgery programs in the United States, members of the Procedural Learning and Safety Collaborative. PARTICIPANTS: Participants included faculty and categorical trainees from 14 general surgery programs. RESULTS: A total of 8681 observations was obtained. The sample included 619 unique residents and 457 different attendings. A total of 598 distinct procedures was performed. In 60% of the cases, the autonomy ratings between trainees and attendings were concordant, with only 3.5% of cases discrepant by more than 1 level. An autonomy perception gap was modeled based on the discrepancy between the trainee and attending Zwisch ratings for the same case. The mean Zwisch score expected for a trainee was lower than the attending across all scenarios. Trainees were more likely to perceive relatively more autonomy in the second half of the year. The autonomy perception gap decreased with increasing case complexity. As trainees gained experience, the perception gap increased with trainees underestimating autonomy. CONCLUSIONS: Trainees and attendings generally demonstrated concordance on autonomy perception scores. However, in 40% of cases, a perception gap exists between trainee and attending with the trainee generally underestimating autonomy. The gap worsens as the trainee progresses through residency. This perception gap suggests that attendings and trainees could be better aligned on teaching goals and expectations.

ABSTRACT

BACKGROUND: Image-guided microwave ablation (MWA) is a technically demanding procedure, involving advanced visual-spatial perception skills. This study sought to create and evaluate a low-cost model and training curriculum for open ultrasound-guided liver tumor MWA. METHODS: Simulated tumors were created, implanted into bovine livers, and visualized by ultrasound. A high-fidelity abdominal model was constructed, with a total cost of $30. Experienced physicians in MWA performed simulated ablations and evaluated the model. Expert performance metrics were established and served as targets for our training curriculum. These included time, number of passes, number of repositionings, and percentage of tumor ablated. Next, 8 novice trainees completed our deliberate practice curriculum. Participants' performances were recorded throughout. RESULTS: Physicians completed a structured feedback questionnaire rating the model's realism and training utility at 8/10 and 10/10, respectively. Tumors appeared hyperechoic and were clearly visualized on ultrasound. Trainees performed a total of 32 ablations. Our trainees' performance improved significantly in all outcomes of interest in the postcurriculum ablations compared to precurriculum ablations. CONCLUSION: We have created a cost-effective, high-fidelity model of MWA, with a deliberate practice curriculum. Trainees can practice to proficiency with clear target metrics prior to participating in clinical cas.

ABSTRACT

OBJECTIVE: Although key clinical skills have been defined in the Core Entrustable Professional Activities, there is a need to improve medical school curricula with standardized training opportunities and assessments of these skills. Thus, we aimed to develop an innovative curriculum that emphasized critical thinking and clinical skills. We hypothesized that we would be able to observe measurable improvement on assessments of students' critical thinking and clinical skills after the implementation of the new curriculum. DESIGN: Prospective, Quasi-Experimental study with the use of historical controls. SETTING: This study took place through the third-year surgical clerkship at the University of Texas Medical Branch at the Galveston, Houston, and Austin, Texas, locations. PARTICIPANTS: A total of 214 students taking the third-year surgical clerkship for the first time during the periods of interest were included. RESULTS: Although the students with traditional curriculum improved 9.5% on a short answer exam from preclerkship to postclerkship completion, the students with new curriculum improved by 40%. Students under the new curriculum performed significantly better on the Objective Structured Clinical Exam; however, their shelf scores were lower. CONCLUSIONS: Under this new curriculum and grading system, we demonstrated that students can be incentivized to improve critical thinking and clinical skills, but this needs to be balanced with knowledge-based incentives.

ABSTRACT

: A workshop on "Simulation Research in Gastrointestinal and Urologic Care: Challenges and Opportunities" was held at the National Institutes of Health in June 2016. The purpose of the workshop was to examine the extent to which simulation approaches have been used by skilled proceduralists (not trainees) caring for patients with gastrointestinal and urologic diseases. The current status of research findings in the use and effectiveness of simulation applications was reviewed, and numerous knowledge gaps and research needs were identified by the faculty and the attendees. The paradigm of "deliberate practice," rather than mere repetition, and the value of coaching by experts was stressed by those who have adopted simulation in music and sports. Models that are most useful for the adoption of simulation by expert clinicians have yet to be fully validated. Initial studies on the impact of simulation on safety and error reduction have demonstrated its value in the training domain, but the role of simulation as a strategy for increased procedural safety remains uncertain in the world of the expert practitioner. Although the basic requirements for experienced physicians to acquire new skills have been explored, the widespread availability of such resources is an unrealized goal, and there is a need for well-designed outcome studies to establish the role of simulation in improving the quality of health care.

ABSTRACT

OBJECTIVE: The objective of this study was to test the hypothesis that distal pancreatectomy (DP) without intraperitoneal drainage does not affect the frequency of grade 2 or higher grade complications. BACKGROUND: The use of routine intraperitoneal drains during DP is controversial. Prior to this study, no prospective trial focusing on DP without intraperitoneal drainage has been reported. METHODS: Patients undergoing DP for all causes at 14 high-volume pancreas centers were preoperatively randomized to placement of a drain or no drain. Complications and their severity were tracked for 60 days and mortality for 90 days. The study was powered to detect a 15% positive or negative difference in the rate of grade 2 or higher grade complications. All data were collected prospectively and source documents were reviewed at the coordinating center to confirm completeness and accuracy. RESULTS: A total of 344 patients underwent DP with (N = 174) and without (N = 170) the use of intraperitoneal drainage. There were no differences between cohorts in demographics, comorbidities, pathology, pancreatic duct size, pancreas texture, or operative technique. There was no difference in the rate of grade 2 or higher grade complications (44% vs. 42%, P = 0.80). There was no difference in clinically relevant postoperative pancreatic fistula (18% vs 12%, P = 0.11) or mortality (0% vs 1%, P = 0.24). DP without routine intraperitoneal drainage was associated with a higher incidence of intra-abdominal fluid collection (9% vs 22%, P = 0.0004). There was no difference in the frequency of postoperative imaging, percutaneous drain placement, reoperation, readmission, or quality of life scores. CONCLUSIONS: This prospective randomized multicenter trial provides evidence that clinical outcomes are comparable in DP with or without intraperitoneal drainage.

ABSTRACT

BACKGROUND: The purpose of this study was to assess the adequacy of current surgical residency and gastroenterology (GI) fellowship flexible endoscopy training as measured by performance on the FES examination. METHODS: Fifth-year general surgery residents and GI fellows across six institutions were invited to participate. All general surgery residents had met ACGME/ABS case volume requirements as well as additional institution-specific requirements for endoscopy. All participants completed FES testing at the end of their respective academic year. Procedure volumes were obtained from ACGME case logs. Curricular components for each specialty and institution were recorded. RESULTS: Forty-eight (28 surgery and 20 GI) trainees completed the examination. Average case numbers for residents were 76 ± 26 colonoscopies and 45 ± 12 EGDs. Among GI fellows, PGY4 s (N = 10) reported 99 ± 64 colonoscopies and 147 ± 79 EGDs. PGY5 s (N = 3) reported 462 ± 307 colonoscopies and 411 ± 260 EGDs. PGY6 GI fellows (N = 7) reported 515 ± 111 colonoscopies and 418 ± 146 EGDs. The overall pass rate for all participants was 75 %, with 68 % of residents and 85 % of fellows passing both the cognitive and skills components. For surgery residents, pass rates were 75 % for manual skills and 85.7 % for cognitive. On the skills examination, Task 2 (loop reduction) was associated with the lowest performance. Skills scores correlated with both colonoscopy (r = 0.46, p < 0.001) and EGD experience (r = 0.46, p < 0.001). Receiver operating characteristics curves were examined among the resident cohort. The minimum number of total cases associated with passing the FES skills component was 103. Significant variability existed in curricular components across institutions. DISCUSSION: These data suggest that current flexible endoscopy training may not be sufficient for all trainees to pass the examination. Implementing additional components of the FEC may prove beneficial in achieving more uniform pass rates on the FES examination.

ABSTRACT

BACKGROUND: The ACGME case log is one of the primary metrics used to determine resident competency; it is unclear if this is an accurate reflection of the residents' role and participation. METHODS: Residents and faculty were independently administered 16-question surveys following each case over a three-week period. The main outcome was agreement between resident and faculty on resident role and percent of the case performed by the resident. RESULTS: Matched responses were collected for 87 cases. Agreement on percent performed occurred in 61% of cases, on role in 63%, and on both in 47%. Disagreement was more often due to resident perception they performed more of the case. Faculty with <10 years experience were more likely to have disagreement compared to faculty with ≥10 years (p = 0.009). CONCLUSIONS: There was a high degree of disagreement between faculty and residents regarding percent of the case performed and role. Accurate understanding of participation and competency is vital for accrediting institutions and for resident self-assessment meriting further study of the causes for this disagreement to improve training and evaluation.

ABSTRACT

INTRODUCTION: Resident satisfaction is a key performance metric for surgery programs; we studied factors influencing resident satisfaction in operative cases, and the concordance of faculty and resident perceptions on these factors. METHODS: Resident and faculty were separately queried on satisfaction immediately following operative cases. Statistical significance of the associations between resident and faculty satisfaction and case-related factors were tested by Chi-square or Fisher's exact test. RESULTS: Residents and faculty were very satisfied in 56/87 (64%) and 36/87 (41%) of cases respectively. Resident satisfaction was associated with their perceived role as surgeon (p < 0.04), performing >50% of the case (p < 0.01), autonomy (p < 0.03), and PGY year 4-5(p < 0.02). Faculty taking over the case was associated with both resident and faculty dissatisfaction. Faculty satisfaction was associated with resident preparation (p < 0.01), faculty perception of resident autonomy (p < 0.01), and faculty familiarity with resident's skills (p < 0.01). CONCLUSIONS: Resident and faculty satisfaction are associated with the resident's competent performance of the case, suggesting interventions to optimize resident preparation for a case or faculty's ability to facilitate resident autonomy will improve satisfaction with OR experience.

ABSTRACT

BACKGROUND: Operations requiring biliary-enteric anastomosis are uncommon, and the true incidence of postoperative stricture is unknown. Our goal was to determine the timing, incidence, and management of stricture after biliary-enteric anastomosis. METHODS: We used 5% Medicare claims data (1996-2011) to identify patients ≥66 years who underwent an operation requiring a biliary-enteric anastomosis. A cumulative incidence curve was used to describe timing of stricture diagnosis. The use of imaging and intervention was evaluated. A Cox proportional hazards model was constructed to identify factors associated with stricture. RESULTS: A total of 3,374 patients underwent an operation requiring either a hepaticojejunostomy (54.33%; N = 1,833) or choledochojejunostomy (45.67%; N = 1,541); 2-year survival was 57.0%. Overall, 403 (11.9%) patients developed a stricture. The cumulative incidence of stricture was 12.5% at 2 years. Mean time to stricture diagnosis was 16.8 ± 21.6 months (median = 8.5 months); 23% of patients with a stricture required hospitalization for cholangitis (N = 94). Only 18 (4.5%) patients with a stricture required reoperation. Younger age (hazard ratio 0.98; 95% confidence interval 0.98-0.99) was associated with a decreased likelihood of stricture formation; presence of an endostent (hazard ratio 1.66; 95% confidence interval 1.35-2.04) predicted stricture formation. CONCLUSION: Biliary-enteric anastomotic strictures occur with significant frequency after a biliary-enteric anastomosis. Although many patients are managed nonoperatively, stricture diagnosis remains burdensome.

ABSTRACT

BACKGROUND: As it addresses both technical and nontechnical skills, simulation-based training is playing an increasingly important role in surgery. In addition to the focus on skill acquisition, it is also important to ensure that surgeons are able to perform a variety of tasks in unique and challenging situations. These situations include responding to mass casualties, dealing with disease outbreaks, and preparing for wartime missions. Simulation-based training can be a valuable training modality in these situations, as it allows opportunities to practice and prepare for high-risk and often low-frequency events. METHODS: During the 8th Annual Meeting of the Consortium of the American College of Surgeons-Accredited Education Institutes in March 2015, a multidisciplinary panel was assembled to discuss how simulation can be used to prepare the surgical community for such high-risk events. CONCLUSION: An overview of how simulation has been used to address needs in each of these situations is presented.

ABSTRACT

BACKGROUND: Laparoscopic liver resection is rapidly expanding with more than 9500 cases performed worldwide. While initial series reported non-anatomic resection of benign peripheral hepatic lesions, approximately 50-65 % of laparoscopic liver resections are now being done for malignant tumors, primarily hepatocellular carcinoma (HCC) or colorectal cancer liver metastases (mCRC). METHODS: We performed a literature review of published studies evaluating outcomes of major laparoscopic liver resection, defined as three or more Couinaud segments. RESULTS: Initial fears of adverse oncologic outcomes or tumor seeding have not been demonstrated, and dozens of studies have reported comparable 5-year disease-free and overall survival between laparoscopic and open resection of HCC or mCRC in case-cohort and propensity score-matched analyses. Increased experience has led to laparoscopic anatomic liver resections including laparoscopic major hepatectomy. A steep learning curve of 45-60 cases is evident for laparoscopic hepatic resection. CONCLUSION: Laparoscopic major hepatectomy is safe and effective in the treatment of benign and malignant liver tumors when performed in specialized centers with dedicated teams. Comparable to other complex laparoscopic surgeries, laparoscopic major hepatectomy has a learning curve of 45-60 cases.

ABSTRACT

BACKGROUND: Tying gentle secure knots is an important skill. We have developed a force feedback simulator that measures force exerted during knot tying. This pilot study examines the benefits of this simulator in a deliberate practice curriculum. METHODS: The simulator consists of silastic tubing with a force sensor. Knot quality was assessed using digital caliper measurement. Participants performed 10 vessel ligations as a pretest, then were shown force readings and tied knots until reaching proficiency targets. Average peak forces precurriculum and postcurriculum were compared using Student t test. RESULTS: Participants exerted significantly less force after completing the curriculum (.61 N ± .22 vs 1.42 N ± .53, P < .001), and had fewer air knots (10% vs 27%). The curriculum was completed in an average of 19.4 ± 6.27 minutes and required an average of 11.7 ± 4.03 knots to reach proficiency. CONCLUSIONS: This study demonstrates the feasibility of real-time feedback in learning to tie delicate knots. The curriculum can be completed in a reasonable amount of time, and may also work as a warm-up exercise before a surgical case.

ABSTRACT

BACKGROUND: Despite numerous efforts to ensure that surgery residents are adequately trained in the areas of laparoscopy and flexible endoscopy, there remain significant concerns that graduates are not comfortable performing many of these procedures. METHODS: Online surveys were sent to surgery residents (98 items, PGY1-5 Categorical) and faculty (78 items, general surgery, and gastrointestinal specialties) at seven institutions. De-identified data were analyzed under an IRB-approved protocol. RESULTS: Ninety-five faculty and 121 residents responded, with response rates of 65 and 52 %, respectively. Seventy-three percent of faculty indicated that competency of their graduating residents were dramatically or slightly worse than previous graduates. Only 29 % of graduating residents felt very comfortable performing advanced laparoscopic (AL) cases and 5 % performing therapeutic endoscopy (TE) cases immediately after graduation. Over half of interns expressed a need for fellowship to feel comfortable performing AL and TE procedures, and this need did not decrease as residents neared graduation. For these procedures, residents receive only "little to some" autonomy, as reported by both faculty and PGY5s. Residents reported that current curricula for laparoscopy and endoscopy consist primarily of clinical experience. Both residents and faculty, though, reported considerable value in other training modalities, including simulations, live animal laboratories, cadavers, and additional didactics. CONCLUSIONS: These data indicate that both residents and faculty perceive significant competency gaps for both laparoscopy and flexible endoscopy, with the most notable shortcomings for advanced and therapeutic cases, respectively. Improvement in resident training methods in these areas is warranted.

ABSTRACT

BACKGROUND: The generative learning model posits that individuals remember content they have generated better than materials created by others. The goals of this study were to evaluate question generation as a study method for the American Board of Surgery In-Training Examination (ABSITE) and determine whether practice test scores and other data predict ABSITE performance. METHODS: Residents (n = 206) from 6 general surgery programs were randomly assigned to one of the two study conditions. One group wrote questions for practice examinations. All residents took 2 practice examinations. RESULTS: There was not a significant effect of writing questions on ABSITE score. Practice test scores, United States Medical Licensing Examination Step 1 scores, and previous ABSITE scores were significantly correlated with ABSITE performance. CONCLUSIONS: The generative learning model was not supported. Performance on practice tests and other data can be used for early identification of residents at risk of performing poorly on the ABSITE.
