Objective: Upwards of 79%-88% of practicing surgeons report musculoskeletal pain due to operating. However, little is known about when these issues begin to become clinically significant. This survey evaluates the prevalence and impact of musculoskeletal pain among surgical residents., Design: After IRB approval, an anonymous 19-question survey based on Cornell Musculoskeletal Discomfort Questionnaire was sent to current surgical residents measuring frequency and degree of pain at 5 sites (neck, shoulder, upper back, lower back, and elbow/wrist) as well as impact on activities both at work and outside of work. Chi square analysis was used to identify differences between groups., Setting: Single academic medical center., Participants: Trainees in all surgical-based specialties., Results: Fifty-three residents responded from 8 different specialties (38% response rate). Respondents were a representative balance of male (53%)/female (47%) with a mean age of 30 ± 2 years. Residents in all specialties and all years of clinical training responded, with the greatest number from general surgery (the largest program with 48% of respondents), second year of clinical training (30%) and an overwhelming 96% of residents reported experiencing pain they felt was due to operating. The most common sites of pain were the neck (92%) and lower back (77%). This pain was a frequent issue for most with 74% reporting multiple times per month and 26% reporting pain nearly every day. Nearly half of residents reported that pain slightly to substantially interfered with their ability to work (44%) and with activities outside of work (47%). Most residents (75%) sought no treatment. No residents missed work despite reporting pain., Conclusions: Musculoskeletal pain begins during training, occurs regularly, and affects function. Neck pain is the most frequent, severe, and disabling site. This provides a target for interventions to reduce the impact of chronic pain on patient care, surgeon wellness, and career longevity., (Copyright © 2023 Association of Program Directors in Surgery.

Background: Simulation-based training is a valuable component of cardiothoracic surgical education. Effective curriculum development requires consensus on procedural components and focused attention on specific learning objectives. Through use of a Delphi process, we established consensus on the steps of video-assisted thoracoscopic surgery (VATS) left upper lobectomy and identified targets for simulation., Methods: Experienced thoracic surgeons were randomly selected for participation. Surgeons voted and commented on the necessity of individual steps comprising VATS left upper lobectomy. Steps with greater than 80% of participants in agreement of their necessity were determined to have established "consensus." Participants voted on the physical or cognitive complexity of each, or both, and chose steps most amenable to focused simulation., Results: Thirty thoracic surgeons responded and joined in the voting process. Twenty operative steps were identified, with surgeons reaching consensus on the necessity of 19. Components deemed most difficult and amenable to simulation included those related to dissection and division of the bronchus, artery, and vein., Conclusions: Through a Delphi process, surgeons with a variety of practice patterns can achieve consensus on the operative steps of left upper lobectomy and agreement on those most appropriate for simulation. This information can be implemented in the development of targeted simulation for VATS lobectomy., (Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc.

We present a low-cost, simple simulation model of major vascular injury repair for cardiothoracic trainees. This model uses commercially available orthopedic elastic bands to allow repetitive practice of the skills necessary during these rare but critical clinical scenarios. Practicing core skills in the simulation setting will help residents be better prepared when the situation arises., (Copyright © 2021 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Objective: The aim of this study was to propose an evidence-based blueprint for training, assessment, and certification of operative performance for surgical trainees., Summary Background Data: Operative skill is a critical aspect of surgical performance. High-quality assessment of operative skill therefore has profound implications for training, accreditation, certification, and the public trust of the profession. Current methods of operative skill assessment for surgeons rely heavily on global assessment strategies across a very broad domain of procedures. There is no mechanism to assure technical competence for individual procedures. The science and scalability of operative skill assessment has progressed significantly in recent decades, and can inform a much more meaningful strategy for competency-based assessment of operative skill than has been previously achieved., Methods: The present article reviews the current status and science of operative skill assessment and proposes a template for competency-based assessment which could be used to update training, accreditation, and certification processes. The proposal is made in reference to general surgery but is more generally applicable to other procedural specialties., Results: Streamlined, routine assessment of every procedure performed by surgical trainees is feasible and would enable a more competency-based educational paradigm. In light of the constraints imposed by both clinical volume and assessment bias, trainees should be expected to become proficient and be measured against a mastery learning standard only for the most important and highest-frequency procedures. For less frequently observed procedures, performance can be compared to a norm-referenced standard and, to provide an overall trajectory of performance, analyzed in aggregate. Key factors in implementing this approach are the number of evaluations, the number of raters, the timeliness of evaluation, and evaluation items., Conclusions: A competency-based operative skill assessment can be incorporated into surgical training, assessment, and certification. The time has come to develop a systematic approach to this issue as a means of demonstrating professional standards worthy of the public trust., Competing Interests: The authors report no conflicts of interest., (Copyright © 2020 Wolters Kluwer Health, Inc.

Objective: Minimally invasive surgery (MIS) is an integral component of General Surgery training and practice. Yet, little is known about how much autonomy General Surgery residents achieve in MIS procedures, and whether that amount is sufficient. This study aims to establish a contemporary benchmark for trainee autonomy in MIS procedures. We hypothesize that trainees achieve progressive autonomy, but fail to achieve meaningful autonomy in a substantial percentage of MIS procedures prior to graduation., Setting/participants: Fifty General Surgery residency programs in the United States, from September 1, 2015 to March 19, 2020. All Categorical General Surgery Residents and Attending Surgeons within these programs were eligible., Design: Data were collected prospectively from attending surgeons and categorical General Surgery residents. Trainee autonomy was assessed using the 4-level Zwisch scale (Show and Tell, Active Help, Passive Help, and Supervision Only) on a smartphone application (SIMPL). MIS procedures included all laparoscopic, thoracoscopic, endoscopic, and endovascular/percutaneous procedures performed by residents during the study. Primary outcomes of interest were "meaningful autonomy" rates (i.e., scores in the top 2 categories of the Zwisch scale) by postgraduate year (PGY), and "progressive autonomy" (i.e., differences in autonomy between PGYs) in MIS procedures, as rated by attending surgeons. Primary outcomes were determined with descriptive statistics, one-way analysis of variance (ANOVA) and Z-tests. Secondary analyses compared (i) progressive autonomy between common MIS procedures, and (ii) progressive autonomy in MIS vs. non-MIS procedures., Results: A total of 106,054 evaluations were performed across 50 General Surgery residency programs, of which 38,985 (37%) were for MIS procedures. Attendings performed 44,842 (42%) of all evaluations, including 16,840 (43%) of MIS evaluations, while residents performed the rest. Overall, meaningful autonomy in MIS procedures increased from 14.1% (PGY1s) to 75.9% (PGY5s), with significant (p < 0.001) increases between each PGY level. Meaningful autonomy rates were higher in the MIS vs. non-MIS group [57.2% vs. 48.0%, p < 0.001], and progressed more rapidly in MIS vs. non-MIS, (p < 0.05). The 7 most common MIS procedures accounted for 83.5% (n = 14,058) of all MIS evaluations. Among PGY5s performing these procedures, meaningful autonomy rates (%) were: laparoscopic appendectomy (95%); laparoscopic cholecystectomy (93%); diagnostic laparoscopy (87%); upper/lower endoscopy (85%); laparoscopic hernia repair (72%); laparoscopic partial colectomy (58%); and laparoscopic sleeve gastrectomy (45%)., Conclusions: US General Surgery residents receive progressive autonomy in MIS procedures, and appear to progress more rapidly in MIS versus non-MIS procedures. However, residents fail to achieve meaningful autonomy in nearly 25% of MIS cases in their final year of residency, with higher rates of meaningful autonomy only achieved in a small subset of basic MIS procedures., (Copyright © 2020.

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., (Copyright © 2020 Association of Program Directors in Surgery.

The extraordinary demands of managing the COVID-19 pandemic has disrupted the world's ability to care for patients with thoracic malignancies. As a hospital's COVID-19 population increases and hospital resources are depleted, the ability to provide surgical care is progressively restricted, forcing surgeons to prioritize among their cancer populations. Representatives from multiple cancer, surgical, and research organizations have come together to provide a guide for triaging patients with thoracic malignancies as the impact of COVID-19 evolves as each hospital., (Copyright © 2020.

Objective: We examined the impact of video editing and rater expertise in surgical resident evaluation on operative performance ratings of surgical trainees., Design: Randomized independent review of intraoperative video., Setting: Operative video was captured at a single, tertiary hospital in Boston, MA., Participants: Six common general surgery procedures were video recorded of 6 attending-trainee dyads. Full-length and condensed versions (n = 12 videos) were then reviewed by 13 independent surgeon raters (5 evaluation experts, 8 nonexperts) using a crossed design. Trainee performance was rated using the Operative Performance Rating Scale, System for Improving and Measuring Procedural Learning (SIMPL) Performance scale, the Zwisch scale, and ten Cate scale. These ratings were then standardized before being compared using Bayesian mixed models with raters and videos treated as random effects., Results: Editing had no effect on the Operative Performance Rating Scale Overall Performance (-0.10, p = 0.30), SIMPL Performance (0.13, p = 0.71), Zwisch (-0.12, p = 0.27), and ten Cate scale (-0.13, p = 0.29). Additionally, rater expertise (evaluation expert vs. nonexpert) had no effect on the same scales (-0.16 (p = 0.32), 0.18 (p = 0.74), 0.25 (p = 0.81), and 0.25 (p = 0.17)., Conclusions: There is little difference in operative performance assessment scores when raters use condensed videos or when raters who are not experts in surgical resident evaluation are used. Future validation studies of operative performance assessment scales may be facilitated by using nonexpert surgeon raters viewing videos condensed using a standardized protocol., (Copyright © 2020 Association of Program Directors in Surgery.

Objectives: To determine whether there is an overall survival (OS) benefit to the addition of thoracic radiation therapy (RT) following R0 resection of pathologic (p) T1 or pT2 N0 M0 small cell lung cancer., Methods: Using the National Cancer Database, we performed a retrospective cohort analysis. Patients who underwent R0 resection for pT1 or p2 N0 M0 small cell lung cancer, stratified by receipt of adjuvant thoracic RT, were compared on the basis of OS using hierarchical Cox Proportional hazards models., Results: Of 4969 patients diagnosed with pT1or pT2 N0 M0 SCLC from 2004 to 2014, 1617 (33%) underwent R0 resection of their primary tumor; of these resected patients, 146 (9.0%) had adjuvant thoracic RT. In unadjusted analysis, there was no significant difference in OS between groups (median survival: surgery alone, 62.2 months vs surgery+RT, 43.8 months; P = .1436). In multivariable analysis, RT was not associated with improved survival (P = .099). There was no significant difference in unadjusted or adjusted survival associated with receipt of RT in both a young and healthy cohort (P = .647 for unadjusted and P = .858 for adjusted) and a matched cohort (P = .867 and P = .954). In the matched cohort, improved OS was associated with younger patient age (adjusted hazard ratio, 1.07; 95% confidence interval, 1.04-1.10; P < .001), female sex (adjusted hazard ratio, 0.68, 95% confidence interval, 0.47-0.97; P = .035), and smaller tumors (adjusted hazard ratio, 1.02; 95% confidence interval, 1.01-1.03; P = .005). Having 2 or more comorbidities was associated with worse OS (adjusted hazard ratio, 2.16; 95% confidence interval, 1.21-3.86; P = .009)., Conclusions: Although complete resection was accomplished in a minority of patients, for these patients, survival was good. The addition of thoracic RT to complete resection does not appear to confer additional survival benefit., (Copyright © 2019. Published by Elsevier Inc.)

Background: Leveraging Internet technologies for academic activities can be complex and expensive, costing tens of thousands of dollars. This report describes an experience in eliminating financial barriers and realizing the potential for a new paradigm in applications for surgical education and practice., Methods: After developing multiple surgical smartphone applications (apps), the report describes the acquisition of skill sets and resources to create state-of-the-art tools. Learning these techniques is nontrivial but is attainable and clearly defined. The report then discusses the trivial costs associated with complex software development, thereby opening new doors to creative uses of technology., Results: Acquisition of coding skills for smartphones took approximately 100 hours. For a simple app without data storage, EuroSCORE (European System for Cardiac Operative Risk Evaluation), total programming time was 25 hours with no additional costs. The more complex autonomy evaluation app, Zwisch Me, was used to evaluate more than 1260 cases from 15 cardiothoracic surgery training programs between January 2016 and August 2018 by using smartphone apps for data collection and a Web dashboard for data reporting. During the first year, all enrollment and data reporting was done manually, at a cost of $124. Automating user enrollment and data reporting increased costs by roughly $240, for an annual expense of $364. Total programming time for this app was approximately 120 hours., Conclusions: Mobile software is underused in the academic surgical arena. The historically large financial barriers to adoption can be overcome by acquisition of coding skills by surgical team members. Direct physician involvement will spawn previously undreamed-of creative applications to enhance practice and education., (Copyright © 2019 The Society of Thoracic Surgeons.

Background: Despite an increasing number of women in the field of surgery, bias regarding cognitive or technical ability may continue to affect the experience of female trainees differently than their male counterparts. This study examines the differences in the degree of operative autonomy given to female compared with male general surgery trainees., Methods: A smartphone app was used to collect evaluations of operative autonomy measured using the 4-point Zwisch scale, which describes defined steps in the progression from novice ("show and tell") to autonomous surgeon ("supervision only"). Differences in autonomy between male and female residents were compared using hierarchical logistic regression analysis., Results: A total of 412 residents and 524 faculty from 14 general surgery training programs evaluated 8,900 cases over a 9-month period. Female residents received less autonomy from faculty than did male residents overall (P < .001). Resident level of training and case complexity were the strongest predictors of autonomy. Even after controlling for potential confounding factors, including level of training, intrinsic procedural difficulty, patient-related case complexity, faculty sex, and training program environment, female residents still received less operative autonomy than their male counterparts. The greatest discrepancy was in the fourth year of training., Conclusion: There is a sex-based difference in the autonomy granted to general surgery trainees. This gender gap may affect female residents' experience in training and possibly their preparation for practice. Strategies need to be developed to help faculty and residents work together to overcome this gender gap., (Copyright © 2019 Elsevier Inc. All rights reserved.)

Training in thoracic surgery has evolved immensely over the past decade due to the advent of integrated programs, technological innovations, and regulations on resident duty hours, decreasing the time trainees have to learn. These changes have made assessment of thoracic surgical trainees even more important. Shifts in medical education have increasingly emphasized competency, which has led to novel competency-based assessment tools for clinical and operative assessment. These novel tools take advantage of simulation and modern technology to provide more frequent and comprehensive assessment of the surgical trainee to ensure competence., (Copyright © 2019 Elsevier Inc.

Objective: The System for Improving and Measuring Procedural Learning (SIMPL) is a smart-phone application used to provide residents with an evaluation of operative autonomy and feedback. This study investigated the perceived benefits and barriers to app use., Design: A database of previously performed SIMPL evaluations was analyzed to identify high, low, and never users. Potential predisposing factors to use were explored. A survey investigating key areas of value and barriers to use for the SIMPL application was sent to resident and faculty users. Respondents were asked to self-identify how often they used the app. The perceived benefits and barriers were correlated with the level of usage. Qualitative analysis of free text responses was used to determine strategies to increase usage., Setting: General surgery training programs who are members of the Procedural Learning and Safety Collaborative., Participants: Surgical residents and faculty., Results: At least 1 SIMPL evaluation was created for 411 residents and 524 faculty. Thirty percent of both faculty and residents were high-frequency users. Thirty percent of faculty were never users. One hundred eighty-eight residents and 207 faculty (response rate 46%) completed the survey. High-frequency resident users were more likely to perceive a benefit for both numerical evaluations (76% vs 30%) and dictated feedback (92% vs 30%). Faculty and residents commonly blamed each other for not creating and completing evaluations regularly (87% of residents, 81% of faculty). Suggested strategies to increase usage included reminders and integration with existing data systems., Contributions: Frequent users perceive value from the application, particularly from dictated feedback and see a positive impact on feedback in their programs. Faculty engagement represents a major barrier to adoption. Mechanisms which automatically remind residents to initiate an evaluation will help improve utilization but programs must work to enhance faculty willingness to respond and dictate feedback., (Copyright © 2019 Association of Program Directors in Surgery.

Objective: In this study we present historic data on adherence to and survival outcomes associated with recently introduced quality measures for the management of non-small-cell lung cancer., Methods: The National Cancer Data Base was queried to identify all patients with non-small-cell lung cancer from 1998 to 2011. Adherence to guidelines was assessed for each of 3 Commission on Cancer-defined quality measures: (1) sampling 10 regional lymph nodes at surgery; (2a) surgery within 120 days of neoadjuvant chemotherapy or, (2b) 180 days of adjuvant chemotherapy; and (3) nonsurgical primary therapy in cN2 disease. The likelihood of measure adherence and the association of measure adherence with all-cause mortality were analyzed controlling for patient, hospital, and time period characteristics., Results: Regional lymph node sampling was inadequate in 72.7% of cases. Only 28.7% began adjuvant chemotherapy within 180 days of surgery. However, 96.5% of patients who received neoadjuvant chemotherapy proceeded to surgery within 120 days and surgery was first-line treatment for cN2 disease in only 3.7% of patients. Uninsured or Medicaid status was an independent risk factor for a prolonged delay between neoadjuvant chemotherapy and surgery (odds ratio, 1.36; 95% confidence interval, 1.08-1.72) and surgery and adjuvant treatment (odds ratio, 1.92; 95% confidence interval, 1.69-2.19). Overall survival was significantly better in patients whose care conformed to quality standards for nodal sampling (measure 1), and timing of chemotherapy., Conclusions: Adherence rates for nodal sampling at the time of surgery and receipt of adjuvant chemotherapy were low. These findings highlight opportunities for improvement efforts, but more measures are needed to more broadly assess the quality of lung cancer care., (Copyright © 2018. Published by Elsevier Inc.)

Objective: To establish the number of operative performance observations needed for reproducible assessments of operative competency., Background: Surgical training is transitioning from a time-based to a competency-based approach, but the number of assessments needed to reliably establish operative competency remains unknown., Methods: Using a smart phone based operative evaluation application (SIMPL), residents from 13 general surgery training programs were evaluated performing common surgical procedures. Two competency metrics were investigated separately: autonomy and overall performance. Analyses were performed for laparoscopic cholecystectomy performances alone and for all operative procedures combined. Variance component analyses determined operative performance score variance attributable to resident operative competency and measurement error. Generalizability and decision studies determined number of assessments needed to achieve desired reliability (0.80 or greater) and determine standard errors of measurement., Results: For laparoscopic cholecystectomy, 23 ratings are needed to achieve reproducible autonomy ratings and 17 ratings are needed to achieve reproducible overall operative performance ratings. For the undifferentiated mix of procedures, 60 ratings are needed to achieve reproducible autonomy ratings and 40 are needed for reproducible overall operative performance ratings., Conclusion: The number of observations needed to achieve reproducible assessments of operative competency far exceeds current certification requirements, yet remains an important and achievable goal. Attention should also be paid to the mix of cases and raters in order to assure fair judgments about operative competency and fair comparisons of trainees.

Background: Tracheal surgery is uncommon, and most of the published literature consists of single-center series over large periods. Our goal was to perform a national, contemporary analysis to identify predictors of major morbidity and mortality based on indication and surgical approach., Methods: The Society of Thoracic Surgeons General Thoracic Surgery Database (STS GTSD) was queried for all patients undergoing tracheal resection between 2002 and 2016. We identified 1,617 cases and compared outcomes by indication and approach. We created a multivariable model for a combined end point of mortality or major morbidity. The relationship between volume and outcome was analyzed., Results: The cervical approach was used 81% of the time, and benign disease was the indication in 75% of cases. Overall 30-day mortality was 1%, and no significant difference was found between the cervical and thoracic approach (1.1% versus 1.6%, p = 0.57) or between benign and malignant indications (1.1% versus 1.5%, p = 0.61). Independent factors associated with morbidity or mortality included thoracic approach, diabetes, and functional status. Centers were divided into those averaging fewer than four resections per year and those performing at least four per year. The low volume (<4) group had a combined morbidity and mortality of 27%, significantly higher than 17% observed among centers with more than four per year (p < 0.0001)., Conclusions: STS GTSD participants perform tracheal resection for benign and malignant disease with low early morbidity and mortality. Higher operative volume is associated with improved outcome. Longer follow-up is needed to confirm airway stability and rate of reoperation., (Copyright © 2018 The Society of Thoracic Surgeons.

Background: We investigated attending surgeon decisions regarding resident operative autonomy, including situations where operative autonomy was discordant with performance quality., Methods: Attending surgeons assessed operative performance and documented operative autonomy granted to residents from 14 general surgery residency programs. Concordance between performance and autonomy was defined as "practice ready performance/meaningfully autonomous" or "not practice ready/not meaningfully autonomous." Discordant circumstances were practice ready/not meaningfully autonomous or not practice ready/meaningfully autonomous. Resident training level, patient-related case complexity, procedure complexity, and procedure commonality were investigated to determine impact on autonomy., Results: A total of 8,798 assessments were collected from 429 unique surgeons assessing 496 unique residents. Practice-ready and exceptional performances were 20 times more likely to be performed under meaningfully autonomous conditions than were other performances. Meaningful autonomy occurred most often with high-volume, easy and common cases, and less complex procedures. Eighty percent of assessments were concordant (38% practice ready/meaningfully autonomous and 42% not practice ready/not meaningfully autonomous). Most discordant assessments (13.8%) were not practice ready/meaningfully autonomous. For fifth-year residents, practice ready/not meaningfully autonomous ratings (9.7%) were more frequent than not practice ready/meaningfully autonomous ratings (7.5%). Ten surgeons (2.3%) failed to afford residents meaningful autonomy on any occasion., Conclusion: Resident operative performance quality is the most important determinant in attending surgeon decisions regarding resident autonomy., (Copyright © 2018 Elsevier Inc.

Purpose of Review: Pericardial effusion is commonly associated with malignancy. The goals of treatment should include optimizing symptom relief, minimizing repeat interventions, and restoring as much functional status as possible., Recent Findings: Pericardiocentesis should be the first intervention but has high recurrence rates (30-60%). For patients with recurrence, repeat pericardiocentesis is indicated in those with limited expected lifespans. Extended pericardial drainage decreases recurrence to 10-20%. The addition of sclerosing agents decreases recurrence slightly but creates significant pain and can lead to pericardial constriction and therefore has fallen out of favor. Most patients with symptomatic pericardial disease have a short median survival time due to their underlying disease. In patients with a longer life expectancy, surgical drainage offers the lowest recurrence rate. Surgical approach is based on effusion location and clinical condition. Subxiphoid and thoracoscopic approaches lead to similar outcomes. Thoracotomy should be avoided as it increases morbidity without improving outcomes.

Objective: We have previously demonstrated the feasibility and validity of a smartphone-based system called Procedural Autonomy and Supervision System (PASS), which uses the Zwisch autonomy scale to facilitate assessment of the operative performances of surgical residents and promote progressive autonomy. To determine whether the use of PASS in a general surgery residency program is associated with any negative consequences, we tested the null hypothesis that PASS implementation at our institution would not negatively affect resident or faculty satisfaction in the operating room (OR) nor increase mean OR times for cases performed together by residents and faculty., Methods: Mean OR times were obtained from the electronic medical record at Northwestern Memorial Hospital for the 20 procedures most commonly performed by faculty members with residents before and after PASS implementation. OR times were compared via two-sample t-test. The OR Educational Environment Measure tool was used to assess OR satisfaction with all clinically active general surgery residents (n = 31) and full-time general surgery faculty members (n = 27) before and after PASS implementation. Results were compared using the Mann-Whitney rank sum test., Results: A significant prolongation in mean OR time between control and study period was found for only 1 of the 20 operative procedures performed at least 20 times by participating faculty members with residents. Based on the overall survey score, no significant differences were found between resident and faculty responses to the OR Educational Environment Measure survey before and after PASS implementation. When individual survey items were compared, while no differences were found with resident responses, differences were noted with faculty responses for 7 of the 35 items addressed although after Bonferroni correction none of these differences remained significant., Conclusions: Our data suggest that PASS does not increase mean OR times for the most commonly performed procedures. Resident OR satisfaction did not significantly change during PASS implementation, whereas some changes in faculty satisfaction were noted suggesting that PASS implementation may have had some negative effect with them. Although the effect on faculty satisfaction clearly requires further investigation, our findings support that use of an autonomy-based OR performance assessment system such as PASS does not appear to have a major negative influence on OR times nor OR satisfaction., (Copyright © 2016 Association of Program Directors in Surgery.

Background: Concerns exist regarding the competency of general surgery graduates with performing core general surgery procedures. Current competence assessment incorporates minimal procedural numbers requirements., Methods: Based on the Zwisch scale we evaluated the level of autonomy achieved by categorical PGY1-5 general surgery residents at 14 U.S. general surgery resident training programs between September 1, 2015 and December 31, 2016. With 5 of the most commonly performed core general surgery procedures, we correlated the level of autonomy achieved by each resident with the number of procedures they had performed before the evaluation period, with the intent of identifying specific target numbers that would correlate with the achievement of meaningful autonomy for each procedure with most residents., Results: Whereas a definitive target number was identified for laparoscopic appendectomy (i.e. 25), for the other 4 procedures studied (i.e. laparoscopic cholecystectomy, 52; open inguinal hernia repair, 42; ventral hernia repair, 35; and partial colectomy, 60), target numbers identified were less definitive and/or were higher than many residents will experience during their surgical residency training., Conclusions: We conclude that procedural target numbers are generally not effective in predicting procedural competence and should not be used as the basis for determining residents' readiness for independent practice., (Copyright © 2017.

Background: Educating residents in the operating room requires balancing patient safety, operating room efficiency demands, and resident learning needs. This study explores 4 factors that influence the amount of autonomy supervising surgeons afford to residents., Methods: We evaluated 7,297 operations performed by 487 general surgery residents and evaluated by 424 supervising surgeons from 14 training programs. The primary outcome measure was supervising surgeon autonomy granted to the resident during the operative procedure. Predictor variables included resident performance on that case, supervising surgeon history with granting autonomy, resident training level, and case difficulty., Results: Resident performance was the strongest predictor of autonomy granted. Typical autonomy by supervising surgeon was the second most important predictor. Each additional factor led to a smaller but still significant improvement in ability to predict the supervising surgeon's autonomy decision. The 4 factors together accounted for 54% of decision variance (r = 0.74)., Conclusion: Residents' operative performance in each case was the strongest predictor of how much autonomy was allowed in that case. Typical autonomy granted by the supervising surgeon, the second most important predictor, is unrelated to resident proficiency and warrants efforts to ensure that residents perform each procedure with many different supervisors., (Copyright © 2017 Elsevier Inc.

Objective: Mock oral examinations are often used to prepare residents for the American Board of Surgery certifying examination. Another potential use of these examinations is to identify programmatic weaknesses. Results from a multi-institutional mock oral examination were evaluated to determine if specific areas of weakness within each of the participating programs could be identified to facilitate program development., Design: A mock oral examination was administered annually consisting of 3 examination rooms per resident with 3 cases in each room. Case categories included core general surgery and subspecialties and cases were changed yearly. Each case included facets of patient management from history and physical examination, and differential diagnosis to postoperative care and professional behaviors., Setting: General Surgery programs at 3 academic medical centers-Northwestern University, Rush University, and University of Illinois at Chicago., Participants: A total of 259 resident examinations of fourth- and fifth-year general surgery residents over a 7-year period., Results: A total of 2331 individual resident cases were evaluated with an overall case pass rate of 50.2% across all 3 programs. The weakest case category for each program was different (A = vascular 40.0% pass, B = trauma 41.4% pass, and C = breast 30.0% pass). All programs scored above their mean in gastrointestinal and abdominal surgery and below their mean in vascular surgery. Within vascular surgery, the weakest facet of patient management also differed between programs (A = select tests 44.3% pass, B = complications 57.0% pass, and C = history and physical 55.4% pass)., Conclusions: A standardized mock oral examination is able to identify topic areas of relative strength and weakness that differ between programs. These results can be used to define focused areas for improvement within training programs, guide rotation schedules, and improve didactic curricula., (Copyright © 2017 Association of Program Directors in Surgery.

Objective: Discrimination against women training in medicine and surgery has been subjectively described for decades. This study objectively documents gender differences in the degree of autonomy given to thoracic surgery trainees in the operating room., Design: Thoracic surgery residents and faculty underwent frame of reference training on the use of the 4-point Zwisch scale to measure operative autonomy. Residents and faculty then submitted evaluations of their perception of autonomy granted for individual operations as well as operative difficulty on a real-time basis using the "Zwisch Me!!" mobile application. Differences in autonomy given to male and female residents were elucidated using chi-square analysis and ordered logistic regression., Setting: Seven academic medical centers with thoracic surgery training programs., Participants: Volunteer thoracic surgery residents in both integrated and traditional training pathways and their affiliated cardiothoracic faculty., Results: Residents (n = 33, female 18%) submitted a total of 596 evaluations to faculty (n = 48, female 12%). Faculty gave less autonomy to female residents with only 56 of 184 evaluations (30.3%) showing meaningful autonomy (passive help or supervision only) compared to 107 of 292 evaluations (36.7%) at those levels for male residents (p = 0.02). Resident perceptions of autonomy showed even more pronounced differences with female residents receiving only 38 of 197 evaluations (19.3%) with meaningful autonomy compared to 133 of 399 evaluations (33.3%) for male residents (p < 0.001). Potential influencing factors explored included attending gender and specialty, case type and difficulty, and resident level of training. In multivariate analysis, only case difficultly, resident gender, and level of training were significantly related to autonomy granted to residents., Conclusions: Evaluations of operative autonomy reveal a significant bias against female residents. Faculty education is needed to encourage allowing female residents more operative autonomy., (Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc.

Objective: Residents frequently report inadequate feedback both in quantity and quality. The study evaluates the quality of faculty feedback about operative performance given using an app-based system., Design: Residents requested operative performance evaluation from faculty on a real-time basis using the "Zwisch Me!!" mobile application which allows faculty to provide brief written feedback. Qualitative analysis of feedback was performed using grounded theory., Setting: The 7 academic medical centers with thoracic surgery training programs., Participants: Volunteer thoracic surgery residents in both integrated and traditional training pathways and their affiliated cardiothoracic faculty., Results: Residents (n = 33) at 7 institutions submitted a total of 596 evaluations to faculty (n = 48). Faculty acknowledged the evaluation request in 476 cases (80%) and in 350 cases (74%) provided written feedback. Initial open coding generated 12 categories of feedback type. We identified 3 overarching themes. The first theme was the tone of the feedback. Encouraging elements were identified in 162 comments (46%) and corrective elements in 230 (65%). The second theme was the topic of the feedback. Surgical technique was the most common category at 148 comments (42.2%) followed by preparation for case (n = 69, 19.7%). The final theme was the specificity of the feedback. Just over half of comments (n = 190, 54.3%) contained specific feedback, which could be applied to future cases. However, 51 comments (14.6%) contained no useful information for the learners., Conclusions: An app-based system resulted in thoracic surgery residents receiving identifiable feedback in a high proportion of cases. In over half of comments the feedback was specific enough to allow improvement. Feedback was better quality when addressing error prevention and surgical technique but was less useful when addressing communication, flow of the case, and assisting. Faculty development around feedback should focus on making feedback specific and actionable, avoiding case descriptions, or simple platitudes., (Copyright © 2017. Published by Elsevier Inc.)

Objective: This study evaluates the current state of the General Surgery (GS) residency training model by investigating resident operative performance and autonomy., Background: The American Board of Surgery has designated 132 procedures as being "Core" to the practice of GS. GS residents are expected to be able to safely and independently perform those procedures by the time they graduate. There is growing concern that not all residents achieve that standard. Lack of operative autonomy may play a role., Methods: Attendings in 14 General Surgery programs were trained to use a) the 5-level System for Improving and Measuring Procedural Learning (SIMPL) Performance scale to assess resident readiness for independent practice and b) the 4-level Zwisch scale to assess the level of guidance (ie, autonomy) they provided to residents during specific procedures. Ratings were collected immediately after cases that involved a categorical GS resident. Data were analyzed using descriptive statistics and supplemented with Bayesian ordinal model-based estimation., Results: A total of 444 attending surgeons rated 536 categorical residents after 10,130 procedures. Performance: from the first to the last year of training, the proportion of Performance ratings for Core procedures (n = 6931) at "Practice Ready" or above increased from 12.3% to 77.1%. The predicted probability that a typical trainee would be rated as Competent after performing an average Core procedure on an average complexity patient during the last week of residency training is 90.5% (95% CI: 85.7%-94%). This falls to 84.6% for more complex patients and to less than 80% for more difficult Core procedures. Autonomy: for all procedures, the proportion of Zwisch ratings indicating meaningful autonomy ("Passive Help" or "Supervision Only") increased from 15.1% to 65.7% from the first to the last year of training. For the Core procedures performed by residents in their final 6 months of training (cholecystectomy, inguinal/femoral hernia repair, appendectomy, ventral hernia repair, and partial colectomy), the proportion of Zwisch ratings (n = 357) indicating near-independence ("Supervision Only") was 33.3%., Conclusions: US General Surgery residents are not universally ready to independently perform Core procedures by the time they complete residency training. Progressive resident autonomy is also limited. It is unknown if the amount of autonomy residents do achieve is sufficient to ensure readiness for the entire spectrum of independent practice.

Background: There is concern about graduating thoracic trainees' independent operative skills due to limited autonomy in training. This study compared faculty and trainee expected levels of autonomy with intraoperative measurements of autonomy for common cardiothoracic operations., Methods: Participants underwent frame-of-reference training on the 4-point Zwisch scale of operative autonomy (show and tell → active help → passive help → supervision only) and evaluated autonomy in actual cases using the Zwisch Me!! mobile application. A separate "expected autonomy" survey elicited faculty and resident perceptions of how much autonomy a resident should have for six common operations: decortication, wedge resection, thoracoscopic lobectomy, coronary artery bypass grafting, aortic valve replacement, and mitral valve repair., Results: Thirty-three trainees from 7 institutions submitted evaluations of 596 cases over 18 months (March 2015 to September 2016). Thirty attendings subsequently provided their evaluation of 476 of those cases (79.9% response rate). Expected autonomy surveys were completed by 21 attendings and 19 trainees from 5 institutions. The six operations included in the survey constituted 47% (226 of 476) of the cases evaluated. Trainee and attending expectations did not differ significantly for senior trainees. Both groups expected significantly higher levels of autonomy than observed in the operating room for all six types of cases., Conclusions: Although faculty and trainees both expect similar levels of autonomy in the operating room, real-time measurements of autonomy show a gap between expectations and reality. Decreasing this gap will require a concerted effort by both faculty and residents to focus on the development of independent operative skills., (Copyright © 2017 The Society of Thoracic Surgeons.

Background: Although error identification and recovery skills are essential for the safe practice of surgery, they have not traditionally been taught or evaluated in residency training. This study validates a method for assessing error identification and recovery skills in surgical residents using a thoracoscopic lobectomy simulator., Methods: We developed a 5-station, simulator-based examination containing the most commonly encountered cognitive and technical errors occurring during division of the superior pulmonary vein for left upper lobectomy. Successful completion of each station requires identification and correction of these errors. Examinations were video recorded and scored in a blinded fashion using an examination-specific rating instrument evaluating task performance as well as error identification and recovery skills. Evidence of validity was collected in the categories of content, response process, internal structure, and relationship to other variables., Results: Fifteen general surgical residents (9 interns and 6 third-year residents) completed the examination. Interrater reliability was high, with an intraclass correlation coefficient of 0.78 between 4 trained raters. Station scores ranged from 64% to 84% correct. All stations adequately discriminated between high- and low-performing residents, with discrimination ranging from 0.35 to 0.65. The overall examination score was significantly higher for intermediate residents than for interns (mean, 74 versus 64 of 90 possible; p = 0.03)., Conclusions: The described simulator-based examination with embedded errors and its accompanying assessment tool can be used to measure error identification and recovery skills in surgical residents. This examination provides a valid method for comparing teaching strategies designed to improve error recognition and recovery to enhance patient safety., (Copyright © 2017 The Society of Thoracic Surgeons.

Background: Practice-based learning is a core competency that is required of residency programs. This study uses a simple written system to encourage structured reflection and describes the experiences residents identify as significant for learning., Methods: Thoracic surgery residents were asked to submit a brief monthly written reflection, highlighting something they learned from a clinical experience. Qualitative analysis of these reflections was performed with grounded theory to generate categories of learning topics. These categories were then combined into themes used to develop theories about how residents learn from their experiences. The frequency of responses within each category was compared between senior and junior residents to examine differences in their approach to learning., Results: Seven residents submitted 56 learning experiences (19 by seniors, 37 by juniors) over a 1-year period. Open coding revealed 113 learning points in 12 unique categories. Procedure choice was the most common category reported. Senior residents were more likely to report learning points that involved procedure choice (31% versus 18%, p = 0.01) and procedure timing (8% versus 2%, p = 0.04) than junior residents. The 12 categories were combined into four themes: evaluation and management; technical skills; complication identification and management; and teamwork and communication. Seniors were more likely to report learning points in the preoperative phase (46% versus 32%, p = 0.01)., Conclusions: Brief written reflection is a feasible approach to encourage thoughtful reflection and practice-based learning. Faculty members should explicitly help residents improve their practice by using individualized guidance and can influence resident learning by asking targeted questions, clarifying decisions, and modeling behavior., (Copyright © 2016 The Society of Thoracic Surgeons.

Purpose: Intraoperative performance assessment of residents is of growing interest to trainees, faculty, and accreditors. Current approaches to collect such assessments are limited by low participation rates and long delays between procedure and evaluation. We deployed an innovative, smartphone-based tool, SIMPL (System for Improving and Measuring Procedural Learning), to make real-time intraoperative performance assessment feasible for every case in which surgical trainees participate, and hypothesized that SIMPL could be feasibly integrated into surgical training programs., Methods: Between September 1, 2015 and February 29, 2016, 15 U.S. general surgery residency programs were enrolled in an institutional review board-approved trial. SIMPL was made available after 70% of faculty and residents completed a 1-hour training session. Descriptive and univariate statistics analyzed multiple dimensions of feasibility, including training rates, volume of assessments, response rates/times, and dictation rates. The 20 most active residents and attendings were evaluated in greater detail., Results: A total of 90% of eligible users (1267/1412) completed training. Further, 13/15 programs began using SIMPL. Totally, 6024 assessments were completed by 254 categorical general surgery residents (n = 3555 assessments) and 259 attendings (n = 2469 assessments), and 3762 unique operations were assessed. There was significant heterogeneity in participation within and between programs. Mean percentage (range) of users who completed ≥1, 5, and 20 assessments were 62% (21%-96%), 34% (5%-75%), and 10% (0%-32%) across all programs, and 96%, 75%, and 32% in the most active program. Overall, response rate was 70%, dictation rate was 24%, and mean response time was 12 hours. Assessments increased from 357 (September 2015) to 1146 (February 2016). The 20 most active residents each received mean 46 assessments by 10 attendings for 20 different procedures., Conclusions: SIMPL can be feasibly integrated into surgical training programs to enhance the frequency and timeliness of intraoperative performance assessment. We believe SIMPL could help facilitate a national competency-based surgical training system, although local and systemic challenges still need to be addressed., (Copyright © 2016.

It is important to realize that guidelines cannot always account for individual variation among patients. They are not intended to supplant physician judgment with respect to particular patients or special clinical situations. Infectious Diseases Society of America considers adherence to these guidelines to be voluntary, with the ultimate determination regarding their application to be made by the physician in the light of each patient's individual circumstances.Coccidioidomycosis, also known as San Joaquin Valley fever, is a systemic infection endemic to parts of the southwestern United States and elsewhere in the Western Hemisphere. Residence in and recent travel to these areas are critical elements for the accurate recognition of patients who develop this infection. In this practice guideline, we have organized our recommendations to address actionable questions concerning the entire spectrum of clinical syndromes. These can range from initial pulmonary infection, which eventually resolves whether or not antifungal therapy is administered, to a variety of pulmonary and extrapulmonary complications. Additional recommendations address management of coccidioidomycosis occurring for special at-risk populations. Finally, preemptive management strategies are outlined in certain at-risk populations and after unintentional laboratory exposure., (© The Author 2016.

Objectives: Lung cancer is the leading cause of cancer-related death in the USA. Regulatory T cells (Tregs) normally function to temper immune responses and decrease inflammation. Previous research has demonstrated different subsets of Tregs with contrasting anti- or pro-inflammatory properties. This study aimed to determine Treg subset distributions and characteristics present in non-small cell lung cancer (NSCLC) patients., Methods: Peripheral blood was collected from healthy controls (HC) and NSCLC patients preceding surgical resection, and mononuclear cells were isolated, stained, and analyzed by flow cytometry. Tregs were defined by expression of CD4 and CD25 and classified into CD45RA(+)Foxp3(int) (naïve, Fr. I) or CD45RA(-)Foxp3(hi) (activated Fr. II). Activated conventional T cells were CD4(+)CD45RA(-)Foxp3(int) (Fr. III)., Results: Samples from 23 HC and 26 NSCLC patients were collected. Tregs isolated from patients with NSCLC were found to have enhanced suppressive function on naive T cells. Cancer patients had significantly increased frequencies of activated Tregs (fraction II: FrII), 17.5 versus 3.2% (P < 0.001). FrII Tregs demonstrated increased RORγt and IL17 expression and decreased IL10 expression compared to Tregs from HC, indicating pro-inflammatory characteristics., Conclusions: This study demonstrates that a novel subset of Tregs with pro-inflammatory characteristics preferentially expand in NSCLC patients. This Treg subset appears identical to previously reported pro-inflammatory Tregs in human colon cancer patients and in mouse models of polyposis. We expect the pro-inflammatory Tregs in lung cancer to contribute to the immune pathogenesis of disease and propose that targeting this Treg subset may have protective benefits in NSCLC.

Background: Despite overwhelming evidence of decreased pain, fewer complications, and shorter length of stay with equivalent oncologic outcomes, video-assisted thoracic surgery (VATS) lobectomy has been slow to be adopted in the community. This study evaluates the role of training surgical assistants to ease the transition to VATS lobectomy., Methods: A half-day training course for physician assistants in the specific skills needed to assist with VATS lobectomy was developed to be offered annually in conjunction with a national meeting. Each participant completed a needs assessment before the course and a course assessment afterward. One-year follow-up data were obtained from the first cohort to determine the effects of the course on their practice., Results: Forty-four physician assistants participated in the course in either 2013 or 2014. Participant-identified educational needs included enhanced camera navigation skills, use of specialized instruments, and knowledge of the steps of the operation to provide proactive assistance. After completing the course, 90% (n = 39) felt more confident in their ability to provide optimal visualization for the operating surgeon, and 93% (n = 40) felt more confident in their ability to recognize and anticipate the steps of a VATS lobectomy. These changes persisted at 1 year., Conclusions: Specific training directed at surgical assistants may improve the adoption of new technology by mechanisms including improved visualization and better understanding of methods to facilitate the operation and avoid frustration. This type of training should be made available to assistants of surgeons learning new operations., (Copyright © 2015 The Society of Thoracic Surgeons. Published by Elsevier Inc.

Objective: To develop operative independence with essential procedures by the end of their training, residents need graded autonomy as they progress through training. This study compares autonomy expectations, as defined by faculty and residents, with autonomy measured in the operating room., Methods: Operative procedures performed by general surgery residents between November 2012 and June 2013 were each assigned an autonomy score by the operating attending physician using a previously described rating scale (Zwisch). Scores range from minimum autonomy, "show and tell," to maximum autonomy, "supervision only." Autonomy expectations were defined by a survey asking faculty and residents what autonomy-level residents should achieve during each year of training for each of the 10 most commonly performed procedures. Faculty expectations, resident expectations, and actual operating room autonomy data were compared using analysis of variance with post hoc analysis by Tukey honestly significant difference test., Results: A total of 1467 operative cases were scored using the Zwisch scale over the period of the study. The 10 most common procedures accounted for 56.3% (827) of the cases. Resident and faculty expectations of resident operative autonomy were similar. For only laparoscopic cholecystectomy, residents expected significantly more autonomy than the faculty did during the junior years but they agreed with the faculty for the chief year. When expectations were compared with actual performance, the resident autonomy level achieved was significantly less than that expected by residents or faculty or both for all 10 procedures in at least one postgraduate level. For every procedure performed more than 5 times during the study period by postgraduate years 3 to 5 residents, autonomy was significantly less than expected., Conclusions: Surgical faculty and residents had similar expectations for resident operative autonomy, yet actual resident performance failed to achieve those shared expectations for even the most common procedures. This autonomy gap provides more evidence for concerns about the preparedness of graduating residents for independent practice., (Copyright © 2014 Association of Program Directors in Surgery.

Purpose: The existing methods for evaluating resident operative performance interrupt the workflow of the attending physician, are resource intensive, and are often completed well after the end of the procedure in question. These limitations lead to low faculty compliance and potential significant recall bias. In this study, we deployed a smartphone-based system, the Procedural Autonomy and Supervisions System, to facilitate assessment of resident performance according to the Zwisch scale with minimal workflow disruption. We aimed to demonstrate that this is a reliable, valid, and feasible method of measuring resident operative autonomy., Methods: Before implementation, general surgery residents and faculty underwent frame-of-reference training to the Zwisch scale. Immediately after any operation in which a resident participated, the system automatically sent a text message prompting the attending physician to rate the resident's level of operative autonomy according to the 4-level Zwisch scale. Of these procedures, 8 were videotaped and independently rated by 2 additional surgeons. The Zwisch ratings of the 3 raters were compared using an intraclass correlation coefficient. Videotaped procedures were also scored using 2 alternative operating room (OR) performance assessment instruments (Operative Performance Rating System and Ottawa Surgical Competency OR Evaluation), against which the item correlations were calculated., Results: Between December 2012 and June 2013, 27 faculty used the smartphone system to complete 1490 operative performance assessments on 31 residents. During this period, faculty completed evaluations for 92% of all operations performed with general surgery residents. The Zwisch scores were shown to correlate with postgraduate year (PGY) levels based on sequential pairwise chi-squared tests: PGY 1 vs PGY 2 (χ(2) = 106.9, df = 3, p < 0.001); PGY 2 vs PGY 3 (χ(2) = 22.2, df = 3, p < 0.001); and PGY 3 vs PGY 4 (χ(2) = 56.4, df = 3, p < 0.001). Comparison of PGY 4 to PGY 5 scores were not significantly different (χ(2) = 4.5, df = 3, p = 0.21). For the 8 operations reviewed for interrater reliability, the intraclass correlation coefficient was 0.90 (95% CI: 0.72-0.98, p < 0.01). Correlation of Procedural Autonomy and Supervisions System ratings with both Operative Performance Rating System items (each r > 0.90, all p's < 0.01) and Ottawa Surgical Competency OR Evaluation items (each r > 0.86, all p's < 0.01) was high., Conclusions: The Zwisch scale can be used to make reliable and valid measurements of faculty guidance and resident autonomy. Our data also suggest that Zwisch ratings may be used to infer resident operative performance. Deployed on an automated smartphone-based system, it can be used to feasibly record evaluations for most operations performed by residents. This information can be used to council individual residents, modify programmatic curricula, and potentially inform national training guidelines., (Copyright © 2014 Association of Program Directors in Surgery.

Conduit failure and conduit airway fistula are rare complications after esophagectomy, however they can be catastrophic resulting in high mortality. Survivors can expect a prolonged hospital course with multiple interventions and an extended period of time prior to being able to resume oral nutrition. High index of suspicion can aid in early diagnosis. Conduit failure usually requires a period of proximal esophageal diversion and staged reconstruction. Conduit airway fistulas may be amenable to endoscopic repair but this has a high failure rate and many patients will require surgical repair with closure of the fistula and interposition of vascularized tissue to minimize recurrence.

Objectives: The American Board of Surgery has mandated intraoperative assessment of general surgery residents, yet the time required to train faculty to accurately and reliably complete operating room performance evaluation forms is unknown. Outside of surgical education, frame-of-reference (FOR) training has been shown to be an effective training modality to teach raters the specific performance indicators associated with each point on a rating scale. Little is known, however, about what form and duration of FOR training is needed to accomplish reliable ratings among surgical faculty., Design: Two groups of surgical faculty separately underwent either an accelerated 1-hour (n = 10) or immersive four-hour (n = 34) FOR faculty development program. Both programs included a formal presentation and a facilitated discussion of sample behaviors for each point on the Zwisch operating room performance rating scale (see DaRosa et al.(8)). The immersive group additionally participated in a small group exercise that included additional practice. After training, both groups were tested using 10 video clips of trainees at various levels. Responses were scored against expert consensus ratings. The 2-sided Mann-Whitney U test was used to compare between group means., Setting and Participants: All trainees were faculty members in the Department of Surgery of a large midwestern private medical school., Results: Faculty undergoing the 1-hour FOR training program did not have a statistically different mean correct response rate on the video test when compared with those undergoing the 4-hour training program (88% vs 80%; p = 0.07)., Conclusions: One-hour FOR training sessions are likely sufficient to train surgical faculty to reliably use a simple evaluation instrument for the assessment of intraoperative performance. Additional research is needed to determine how these results generalize to different assessment instruments., (© 2013 Association of Program Directors in Surgery. Published by Elsevier Inc.

The operating room (OR) remains primarily a master/apprenticeship-based learning environment for surgical residents. Changes in surgical education and health care systems challenge faculty to efficiently and effectively graduate residents truly competent in operations classified by the Surgical Council on Resident Education as "common essential" and "uncommon essential." Program directors are charged with employing resident evaluation systems that yield useful data, yet feasible enough to fit into a busy surgical faculty member's workflow. This paper proposes a simple model for teaching and assessing residents in the operating room to guide faculty and resident interaction in the OR, and designating a resident's earned level of autonomy for a given procedure. The system as proposed is supported by theories associated with motor skill acquisition and learning., (Copyright © 2012 Association of Program Directors in Surgery. Published by Elsevier Inc.

Background: Research suggests a benefit from a skills curriculum emphasizing error prevention, identification, and management. Our purpose was to identify common errors committed by trainees during simulated thoracoscopic lobectomy for use in developing an error-based curriculum., Methods: Twenty-one residents (postgraduate years 1 to 8) performed a thoracoscopic left upper lobectomy on a previously validated simulator. Videos of the procedure were reviewed in a blinded fashion using a checklist listing 66 possible cognitive and technical errors., Results: Of the 21 residents, 15 (71%) self-reported completing the anatomic lobectomy; however, only 7 (33%) had actually divided all of the necessary structures correctly. While dissecting the superior pulmonary vein, 16 residents (76%) made at least one error. The most common (n=13, 62%) was dissecting individual branches rather than the entire vein. On the bronchus, 14 (67%) made at least one error. Again, the most common (n=9, 43%) was dissecting branches. During these tasks, cognitive errors were more common than technical errors. While dissecting arterial branches, 18 residents (86%) made at least one error. Technical and cognitive errors occurred with equal frequency during arterial dissection. The most common arterial error was excess tension on the vessel (n=10, 48%)., Conclusions: Curriculum developers should identify skill-specific technical and judgment errors to verify the scope of errors typically committed. For a thoracoscopic lobectomy curriculum, emphasis should be placed on correct identification of anatomic landmarks during dissection of the vein and airway and on proper tissue handling technique during arterial dissection., (Copyright © 2012 The Society of Thoracic Surgeons.

Objectives: Although simulation is considered integral to general surgery training, its role has only recently been recognized in thoracic surgical education, perhaps due to a lack of widely available, validated simulators for advanced thoracic procedures. This study evaluates the construct, content and face validity of an inexpensive, easily reproducible simulator for teaching thoracoscopic lobectomy., Methods: Construct validity (ability of the simulator to discriminate between users of different skill levels) was assessed by having surgical trainees perform a lobectomy on the simulator. Participants were divided into three groups (experienced, intermediate and novice) based on self-reported experience with minimally invasive surgery. After instruction and practice time to limit the effect of any simulator-specific learning curve, each performed a left upper lobectomy that was scored using a standardized assessment tool incorporating total time plus weighted penalty minutes assigned for errors. Content validity (simulator requires same steps and decision-making as a clinical lobectomy) was assessed using a Likert scale by those participants who had previously seen a thoracoscopic lobectomy in a patient., Results: Thirty-one residents participated in the study (12 experienced, 6 intermediate and 13 novice). All 12 experienced participants completed the lobectomy. The other groups were less successful with 4 of 6 in the intermediate group and 5 of 13 in the novice group completing the lobectomy (P = 0.004). The mean times for lobectomy + penalty minutes were 35 + 6.8 (experienced), 50 + 13 (intermediate) and 54 + 20 (novice). Differences between groups were statistically significant for experienced vs. novice (P < 0.001) and experienced vs. intermediate (P < 0.04). Content validity was assessed by the 18 participants who had previously seen a thoracoscopic lobectomy with a mean of 9.2 of 10 possible points., Conclusions: The thoracoscopic lobectomy simulator used in this study demonstrates acceptable validity and can be a useful tool for teaching thoracoscopic lobectomy to trainees or experienced surgeons.

Objective: : As the population continues to age, more benign and malignant lung lesions requiring surgical intervention are being identified in elderly patients. Historically, advanced age has been used to justify performing wedge resection rather than a lobectomy in elderly patients. The introduction of thoracoscopic surgery has resulted in improved short-term outcomes compared with thoracotomy. The objective of this study is to compare short-term outcomes of thoracoscopic lung resection in elderly patients to that in younger patients., Methods: : A retrospective review was performed of all patients undergoing thoracoscopic anatomic lobectomy without previous chemotherapy or radiation between April 2006 and April 2009. Patient charts were reviewed to determine risk factors, perioperative complications, and length of stay. Student's t test was used for comparison between groups., Results: : Over the period studied, 86 patients underwent thoracoscopic lobectomy. Forty of them were 70 years or older. Baseline pulmonary function testing showed an average FEV1 of 85% predicted (81% younger vs 90% older, P = nonsignificant). Median chest tube duration was 3 days and median length of stay was 4 days in both groups. The overall incidence of perioperative complications was 21% and was not different in the two groups (20% younger vs 22% older)., Conclusions: : Elderly patients with good baseline pulmonary function tolerate thoracoscopic lobectomy as well as younger patients. Advanced age alone should not be considered a contraindication to lobectomy in the era of thoracoscopy. Elderly patients should be offered lobectomy rather than wedge resection on the basis of the same criteria used in younger patients.

Purpose: Simulation is rapidly becoming an integral part of surgical education at all levels including the education of practicing surgeons in new techniques such as thoracoscopic lobectomy. Current thoracoscopic lobectomy simulator models have significant limitations including expense and requirement for specialized facilities. This study describes a novel low-cost, easily reproducible, bench top simulator., Description: Tissue blocks consisting of a porcine heart and bilateral lungs with intact pericardium were secured from a commercially available source. The pulmonary artery and veins were statically distended with ketchup to more realistically mimic the technique of dissection and allow for simultaneous identification of technical errors., Evaluation: This simulator has been used at seven different industry and society sponsored thoracoscopic lobectomy training programs by more than 100 participants. Qualitative data on the performance of the model was collected from faculty and course participants., Conclusions: A low-cost porcine heart-lung block statically perfused with ketchup provides an inexpensive, easily reproducible model for teaching thoracoscopic lobectomy, which reasonably and accurately simulates a clinical experience., (2010 The Society of Thoracic Surgeons.
