Twelve tips for creating a works in progress conference that builds capacity for educational scholarship and creates a scholarly community.

Educators have implemented various strategies to build capacity for education scholarship, and often, these strategies focus on a specific set of interested individuals. We perceived a need for a strategy to engage a health professions education community with peer support. The purpose of these 12 tips is to describe an approach in place for nearly two decades that concurrently advances education scholarship and fosters a community that welcomes novices to experts. The approach is based on principles that not only build capacity and community but also stress the importance of alignment with the institution's missions. The tips guide setting up, conducting, and sustaining such an approach.

Improving Medical Student Performance With Unsupervised Simulation and Remote Asynchronous Feedback.

OBJECTIVE: This study aims to assess the effectiveness of training medical students to perform two clinical procedures using unsupervised simulation with remote asynchronous feedback, compared to an intensive workshop with in-person feedback. DESIGN, SETTING, AND PARTICIPANTS: Third-year medical students were recruited and randomized into 2 groups: Thoracentesis or paracentesis. Within each group, participants were further randomized into either unsupervised simulation with remote asynchronous feedback (experimental group; EG) or a 2-hour workshop (control group; CG). The EG underwent two unsupervised 20-minute training sessions and received remote asynchronous feedback. The CG had a 2-hour workshop where they received in-person feedback. After training, students were assessed using the objective structured assessment of technical skills (OSATS) scale. Twenty students in thoracentesis and 23 in paracentesis training completed the 2 training sessions with remote and asynchronous feedback, and 30 students for both thoracentesis and paracentesis groups completed the 2-hour workshop. RESULTS: The EG achieved a significantly higher passing rate than the CG on both procedures (thoracentesis 80% vs. 43%, paracentesis 91% vs. 67%, p-value< 0.05). CONCLUSION: The asynchronous educational method allowed EG students to achieve higher performance than CG students. This novel modality allowed students and instructors to train and assess at their own pace.

Novel paediatric case of a spinal high-grade astrocytoma with piloid features in a patient with Noonan Syndrome.

Noonan Syndrome (NS) is associated with an increased risk of low-grade central nervous system tumours in children but only very rarely associated with high-grade gliomas. Here we describe the first reported case of a spinal high-grade astrocytoma with piloid features (HGAP) in a child with NS. This case was a diagnostic and treatment dilemma, prior to whole-genome germline and tumour sequencing, tumour transcriptome sequencing and DNA methylation analysis. The methylation profile matched strongly with HGAP and sequencing identified somatic FGFR1 and NF1 variants and a PTPN11 germline pathogenic variant. Therapeutic targets were identified but also alterations novel to HGAP such as differential expression of VEGFA and PD-L1. The germline PTPN11 finding has not been previously described in individuals with HGAP. This case underscores the power of precision medicine from a diagnostic, therapeutic and clinical management perspective, and describes an association between HGAP and NS which has not previously been reported.

Consensus guidelines on the bedside assistant skills required in robotic surgery.

BACKGROUND: While bedside assistants play a critical role in many robotic operations, substantial heterogeneity remains in bedside assistant training pathways. As such, this study aimed to develop consensus guidelines for bedside assistant skills required for team members in robotic operations. METHODS: We designed a study using the Delphi process to develop consensus guidelines around bedside assistant skills. We generated an initial list of bedside assistant skills from the literature, training materials, and expert input. We selected experts for the Delphi process based on prior scholarship in the area of robotic bedside assistant education and experience facilitating robotic bedside assistant training. For each item, respondents specified which robotic team members should have the skill from a list of "basic" bedside assistants, "advanced" bedside assistants, surgeons, surgical technologists, and circulating nurses. We conducted two rounds of the Delphi process and defined 80% agreement as sufficient for consensus. RESULTS: Fourteen experts participated in two rounds of the Delphi process. By the end of the second round, the group had reached consensus on 253 of 305 items (83%). The group determined that "basic" bedside assistants should have 52 skills and that "advanced" bedside assistants should have 60 skills. The group also determined that surgeons should have 54 skills, surgical technologists should have 25 skills, and circulating nurses should have 17 skills. Experts agreed that all participants should have certain communication skills and basic knowledge of aspects of the robotic system. CONCLUSIONS: We developed consensus guidelines on the skills required during robotic surgery by bedside assistants and other team members using the Delphi process. These findings can be used to design training around bedside assistant skills and assess team members to ensure that each team member has the appropriate skills. Hospitals can also use these guidelines to standardize expectations for robotic team members.

Therapeutic Opportunities for Biomarkers in Metastatic Spine Tumors.

For many spine surgeons, patients with metastatic cancer are often present in an emergent situation with rapidly progressive neurological dysfunction. Since the Patchell trial, scoring systems such as NOMS and SINS have emerged to guide the extent of surgical excision and fusion in the context of chemotherapy and radiation therapy. Yet, while multidisciplinary decision-making is the gold standard of cancer care, in the middle of the night, when a patient needs spinal surgery, the wealth of chemotherapy data, clinical trials, and other medical advances can feel overwhelming. The goal of this review is to provide an overview of the relevant molecular biomarkers and therapies driving patient survival in lung, breast, prostate, and renal cell cancer. We highlight the molecular differences between primary tumors (i.e., the patient's original lung cancer) and the subsequent spinal metastasis. This distinction is crucial, as there are limited data investigating how metastases respond to their primary tumor's targeted molecular therapies. Integrating information from primary and metastatic markers allows for a more comprehensive and personalized approach to cancer treatment.

SpliceVarDB: A comprehensive database of experimentally validated human splicing variants.

Variants that alter gene splicing are estimated to comprise up to a third of all disease-causing variants, yet they are hard to predict from DNA sequencing data alone. To overcome this, many groups are incorporating RNA-based analyses, which are resource intensive, particularly for diagnostic laboratories. There are thousands of functionally validated variants that induce mis-splicing; however, this information is not consolidated, and they are under-represented in ClinVar, which presents a barrier to variant interpretation and can result in duplication of validation efforts. To address this issue, we developed SpliceVarDB, an online database consolidating over 50,000 variants assayed for their effects on splicing in over 8,000 human genes. We evaluated over 500 published data sources and established a spliceogenicity scale to standardize, harmonize, and consolidate variant validation data generated by a range of experimental protocols. According to the strength of their supporting evidence, variants were classified as "splice-altering" (∼25%), "not splice-altering" (∼25%), and "low-frequency splice-altering" (∼50%), which correspond to weak or indeterminate evidence of spliceogenicity. Importantly, 55% of the splice-altering variants in SpliceVarDB are outside the canonical splice sites (5.6% are deep intronic). These variants can support the variant curation diagnostic pathway and can be used to provide the high-quality data necessary to develop more accurate in silico splicing predictors. The variants are accessible through an online platform, SpliceVarDB, with additional features for visualization, variant information, in silico predictions, and validation metrics. SpliceVarDB is a very large collection of splice-altering variants and is available at https://splicevardb.org.

Social determinants of health and outcome disparities in spine tumor surgery. Part 2: Neighborhood disadvantage and long-term outcomes.

OBJECTIVE: Neighborhood-level resource disadvantage has been previously shown to predict extent of resection, oncological follow-up, adjuvant treatment, and clinical trial participation for malignancies, including glioblastoma. The authors aimed to characterize the association between neighborhood disadvantage and long-term outcomes after spine tumor surgery. METHODS: The authors analyzed all patients who underwent surgery for primary or secondary (all metastatic pathologies) spine tumors at a single spinal oncology specialty center in the United States from 2015 to 2022. The Area Deprivation Index (ADI), a validated metric compositing 17 social determinants of health variables that ranges continuously from 0% (higher advantage) to 100% (higher disadvantage), was used to quantify neighborhood disadvantage. Patient addresses were matched to ADI on the basis of the census block of residence. Subsequently, the study population was dichotomized into advantaged (ADI 0%-33%) and disadvantaged (ADI 34%-100%) cohorts. The primary endpoint was functional status, as defined by Eastern Cooperative Oncology Group (ECOG) Performance Status Scale grade, with secondary endpoints including inpatient outcomes, mortality, readmissions, reoperations, and clinical research participation. Multivariable logistic, gamma log-link, and Cox regression adjusted for 14 confounders, including patient and oncological characteristics, general and tumor-related presenting severity, and treatment. RESULTS: In total, 237 patients underwent spine tumor surgery from 2015 to 2022, with an average age of 53.9 years, and 57.0% had primary tumors whereas 43.0% had secondary tumors; 55.3% (n = 131) were classified by ADI into the disadvantaged cohort. This cohort had higher rates of ambulation deficits on presentation (39.1% vs 23.5%, p = 0.015) and nonelective surgery (35.1% vs 23.6%, p = 0.030). Postoperatively, disadvantaged patients exhibited higher odds of residual tumor (OR 2.55, p = 0.026), especially for secondary tumors (OR 4.92, p = 0.045). Patients from disadvantaged neighborhoods additionally exhibited significantly higher odds of poor functional status at follow-up (OR 3.94, p = 0.002). Postoperative survival was 74.7% (mean follow-up 17.6 months), with the disadvantaged cohort experiencing significantly shorter survival (HR 1.92, p = 0.049). Moreover, this population had higher odds of readmission (OR 1.92, p = 0.046) and, for primary tumors, reoperation (OR 9.26, p = 0.005). Elective participation in prospective clinical research was lower among the disadvantaged cohort (OR 0.45, p = 0.016). CONCLUSIONS: Neighborhood disadvantage predicts higher rates of residual tumor, readmission, and reoperation, as well as poorer functional status, shorter postoperative survival, and decreased elective research participation. The ADI may be used to risk stratify spine oncology patients and guide targeted interventions to ameliorate neurosurgical disparities and to reduce barriers to research participation.

Social determinants of health and outcome disparities in spine tumor surgery. Part 1: An analysis of 6.6 million nationwide admissions.

OBJECTIVE: Earlier research has demonstrated that social determinants of health (SDoH) impact neurosurgical access and outcomes, but these trends are less characterized for spine tumors relative to intracranial tumors. The authors aimed to elucidate the association between SDoH and outcomes for a nationwide cohort of spine tumor surgery admissions. METHODS: The authors identified all admissions with a spine tumor diagnosis in the National Inpatient Sample (NIS) from 2002 to 2019. Four SDoH were analyzed: race and ethnicity, insurance, household income, and safety-net hospital (SNH) treatment. Hospitals in the top quartile of safety-net burden (in terms of percentage of patients receiving Medicaid or uninsured) were categorized as SNHs. Multivariable regression queried the association between 22 variables and 5 perioperative outcomes: mortality, discharge disposition, complications, length of stay (LOS), and hospitalization costs. Interaction term analysis with hospitalization year was used to assess longitudinal changes in outcome disparities. Finally, the authors constructed random forest machine learning models to assess the impact of SDoH variables on prognostic accuracy and to quantify the relative importance of predictors for disposition. RESULTS: Of 6,593,392 total admissions with spine tumors, 219,380 (3.3%) underwent surgery. Non-White race (OR 0.80-0.91, p < 0.001) and nonprivate insurance (OR 0.76-0.83, p < 0.001) were associated with lower odds of receiving surgery. Among surgical admissions, presenting severity, including of myelopathy and plegia, was elevated among non-White, nonprivate insurance, and low-income admissions (all p < 0.001). Black race (OR 0.70, p < 0.001), Medicare (OR 0.70, p < 0.001), Medicaid (OR 0.90, p < 0.001), and lower income (OR 0.88-0.93, all p < 0.001) were associated with decreased odds of favorable discharge disposition. Increased LOS and costs were observed among non-White (+6%-10% in LOS and +5%-9% in costs, both p < 0.001) and Medicaid (+16% in LOS and +6% in costs, both p < 0.001) admissions. SNH treatment was also associated with higher mortality (OR 1.49, p < 0.001) and complication (OR 1.20, p < 0.001) rates. From 2002 to 2019, disposition improved annually for Medicaid patients (OR 1.03 per year, p = 0.022) but worsened for Black patients (OR 0.98 per year, p = 0.046). Random forest models identified household income as the most important predictor of discharge disposition. CONCLUSIONS: For spine tumor admissions, SDoH predicted surgical intervention, presenting severity, and perioperative outcomes. Over 2 decades, disparities improved for Medicaid patients but worsened for Black patients. Finally, SDoH significantly improve prognostic accuracy for outcomes after spine tumor surgery. Further study toward ameliorating patient disparities for this population is warranted.

"When You're in It, It Feels Like It's Everything": Medical Students' Experience of Failure and Remediation in the United States and the Netherlands.

PURPOSE: Medical training institutions worldwide must be prepared to remediate struggling learners, but there is little empirical evidence around learners' perspectives on remediation efforts. Research shows that emotion has a significant effect on learning, but it has not been well studied in remediation in medical education. Given the high stakes of remediation, understanding more about learners' emotional experience could lead to improvements in remediation programs. This study aimed to explore medical students' emotional experience of failure and remediation to offer opportunities to improve remediation. METHOD: This study is a thematic analysis of data collected from July to September 2022 from one-to-one interviews with students from 4 institutions (2 in the United States and 2 in the Netherlands) who had not met expectations on 1 or more medical school assessment(s). Interview questions explored students' experiences with learning of and responding to a performance that was below expected standards, with probes around any mentions of emotions. RESULTS: Fourteen students participated: 9 from schools in the United States and 5 from schools in the Netherlands. The students perceived the failure and remediation event to be highly significant, reflecting negatively on their suitability for a career as a physician. We identified 5 themes: (1) shame was pervasive and only retrospectively perceived as unwarranted; (2) self-doubt was common and weighty; (3) resentment, blame, and other external-facing emotions were present but softened over time; (4) worry and stress related to perceived career effect differed across countries; and (5) students had mixed emotional reactions to the remediation process. CONCLUSIONS: Medical students have strong emotional responses to failure and remediation. Expecting and considering emotions such as shame, self-doubt, and anger could help educators design better remediation programs. Differences across countries may be at least partially explained by different degrees of time variability and flexibility within the curricula.

Avoiding common pitfalls in mixed methods research?

This column is intended to address the kinds of knotty problems and dilemmas with which many scholars grapple in studying health professions education. In this article, the authors focus on how to help mentees take an analytic approach to improve their mixed methods work. Mixed methods research has increased in popularity and with that comes both strengths and weaknesses in these studies. We suggest key elements to look for when reading a mixed methods research paper. We also provide guidance around weaknesses we have noticed in reporting.

Streamlining the Journey of Research Into Clinical Practice: Making Your Patients and Practice Flourish Understanding and Setting Treatment Expectations for Patients With Metastatic Spine Tumors.

STUDY DESIGN: Literature review with clinical recommendation. OBJECTIVE: A concise curation of the latest spine literature exploring the relationship between expectations and satisfaction for patients with metastatic spinal disease (MSD). Deliver recommendations to practicing clinicians regarding interpretation and utilisation of this evidence. METHODS: The latest spine literature in the topic of factors affecting the expectations of patients with MSD was reviewed and clinical recommendations were formulated. Recommendations are graded as strong or Conditional. RESULTS: 5 articles were selected. Article 1: risk factors for the development of dissatisfaction from a cohort of 362 MSD patients. Strong recommendation to incorporate risk factor assessment when considering treatment. Article 2: systematic review assessing the relationship between pre-operative patient expectations and subsequent satisfaction in allied disciplines. Conditional recommendation to optimize patient expectation to positively modify patient satisfaction. Article 3: qualitative study of how clinicians, from different specialties, counsel patients with MSD pre-treatment. Strong recommendation to use a multidisciplinary approach. Article 4 qualitative study of how MSD patients experience their pre-treatment counselling and how that affected their appreciation of treatment success. Conditional recommendation to furnish patients with tailored, expected outcomes in the context of systemic progression. Article 5 Design and validation of a pre-treatment questionnaire specific to MSD. A conditional recommendation to incorporate this questionnaire in clinical and research MSD practice. CONCLUSION: Patients with MSD are approaching end of life care and high levels of treatment satisfaction are crucial at this juncture. The role of expectation management and comprehensive counselling is critical.

Comparing observed and preferred instruction in robotic surgery.

BACKGROUND: The unique setup of robotic surgery challenges the traditional instructional dynamic between surgical learners and teachers. Previous studies have posited difficulties such as reliance on observational learning and ease of takeover. However, we lack understanding of how these instructional challenges manifest and are perceived by learners. Improving instruction has the potential to optimize education and performance in robotic surgery. METHODS: In this qualitative study, we conducted robotic case observations and learner interviews focusing on instruction in robotic surgery. We deductively generated codes in a theory-informed manner after review of the instructional literature in surgery, medicine, and other fields. We applied these codes in a rigorous directed content analysis of field notes and transcripts to identify themes. RESULTS: Thirty-eight faculty, fellows, and residents participated in 10 robotic cases and 20 semistructured interviews. Observed practices on the basis of case observations differed substantially from preferred practices on the basis of interview data. Using 37 codes, we identified 4 main themes related to instruction in robotic surgery: contextualization, individualization, autonomy, and multimodality. We contrasted observed and preferred instruction in each of these areas to generate instructional considerations that may better align preferences and practices. CONCLUSIONS: We observed several suboptimal instructional practices that contradicted preferred ways of learning. We suggested robotic-specific instructional considerations such as using multimodality to promote active learning and to reduce ambiguity. We also provided considerations applicable to all types of surgery, such as to include rationale to promote learning consolidation and to frame operative steps to allow trainees to plan their participation.

Vascular Anastomoses and Dissection: A Six-Part Simulation Curriculum for Surgical Residents.

Introduction: As surgical technologies grow, so too do demands on surgical trainees to master increasing numbers of skill sets. With the rise of endovascular surgery, trainees have fewer opportunities to practice open vascular techniques in the operating room. Simulation can bridge this gap. However, existing published open vascular simulation curricula are basic or based on expensive models. Methods: We iteratively developed an open vascular skills curriculum for second-year surgery residents comprising six 2-hour sessions. We refined the curriculum based on feedback from learners and faculty. The curriculum required skilled facilitators, vascular instruments, and tissue models. We evaluated the latest iteration with a survey and by assessing participants' technical skills using the Objective Structured Assessment of Technical Skills (OSATS) form. Results: Over the past 10 years, 101 residents have participated in the curriculum. Nine of 13 residents who participated in the latest curricular iteration completed the survey. All respondents rated the sessions as excellent and strongly agreed that they had improved their abilities to perform anastomoses with tissue and prosthetic. Facilitators completed 18 OSATS forms for residents in the fifth and sixth sessions of the latest iteration. Residents scored well overall, with a median 26.5 (interquartile range: 24-29) out of a possible score of 35, with highest scores on knowledge of instruments. Discussion: This simulation-based curriculum facilitates open vascular surgical skill acquisition among surgery residents. The curriculum allows residents to acquire critical vascular skills that are challenging to learn in an increasingly demanding operative setting.

An At-Home Laparoscopic Curriculum for Junior Residents in Surgery, Obstetrics/Gynecology, and Urology.

Introduction: Laparoscopic surgery requires significant training, and prior studies have shown that surgical residents lack key laparoscopic skills. Many educators have implemented simulation curricula to improve laparoscopic training. Given limited time for dedicated, in-person simulation center practice, at-home training has emerged as a possible mechanism by which to expand training and promote practice. There remains a gap in published at-home laparoscopic curricula employing embedded feedback mechanisms. Methods: We developed a nine-task at-home laparoscopic curriculum and an end-of-curriculum assessment following Kern's six-step approach. We implemented the curriculum over 4 months with first- to third-year residents. Results: Of 47 invited residents from general surgery, obstetrics/gynecology, and urology, 37 (79%) participated in the at-home curriculum, and 25 (53%) participated in the end-of-curriculum assessment. Residents who participated in the at-home curriculum completed a median of six of nine tasks (interquartile range: 3-8). Twenty-two residents (47%) responded to a postcurriculum survey. Of these, 19 (86%) reported that their laparoscopic skills improved through completion of the curriculum, and the same 19 (86%) felt that the curriculum should be continued for future residents. Residents who completed more at-home curriculum tasks scored higher on the end-of-curriculum assessment (p = .009 with adjusted R 2 of .28) and performed assessment tasks in less time (p = .004 with adjusted R 2 of .28). Discussion: This learner-centered laparoscopic curriculum provides guiding examples, spaced practice, feedback, and graduated skill development to enable junior residents to improve their laparoscopic skills in a low-stakes, at-home environment.

How Many Is Too Many? Using Cognitive Load Theory to Determine the Maximum Safe Number of Inpatient Consultations for Trainees.

PURPOSE: Cognitive load, specifically extraneous load (EL) reflective of distractions, may provide evidence of a lack of focus, potentially making additional work unsafe. The assessment of trainees performing inpatient consultations provides a helpful model for examining this question. The goal of this study was to provide useful information to clinical and educational leaders to optimize inpatient consultation services and rotations and mitigate potential patient safety risk. METHOD: In 2019, using the Consult Cognitive Load instrument, the authors obtained EL data from inpatient consultations performed by internal medicine fellows and psychiatry residents across 5 University of California hospitals. In 2023, the authors constructed a Wright map to compare the participants' EL data with the number of prior initial consultations performed during the shift. RESULTS: Of 326 trainees contacted, 139 (43%) completed the EL survey items. The Wright map shows that trainees were estimated to agree that interruptions were already distracting at the first consultation of the shift. After 4 consultations, trainees were estimated to strongly agree that interruptions were distracting and to agree that emotions, extraneous information, and technology were distracting. CONCLUSIONS: The authors propose a quantitative, empirically driven, mean safety limit of 4 new inpatient consultations per shift for trainees to avoid cognitive overload, thereby potentially supporting patient safety. Clinical and educational leaders can adjust this limit to fit the unique needs of their practice setting. A similar approach using cognitive load and item response theory could be used to conduct patient safety research in other domains.

Who should proof my paper?

This column is intended to address the kinds of knotty problems and dilemmas with which many scholars grapple in studying health professions education. In this article, the authors address the challenges in proofreading a manuscript. Emerging researchers might think that someone in the production team will catch any errors. This may not always be the case. We emphasize the importance of guiding mentees to take the process of preparing a manuscript for submission seriously.

Comparing Peer and Faculty Feedback for Asynchronous Laparoscopic Skill Acquisition.

OBJECTIVE: Traditionally, expert surgeons have provided surgical trainees with feedback about their simulation performance, including for asynchronous practice. Unfortunately, innumerable time demands may limit experts' ability to provide feedback. It is unknown whether and how peer feedback is an effective mechanism to help residents acquire laparoscopic skill in an asynchronous setting. As such, we aimed to assess the effect of peer feedback on laparoscopic performance and determine how residents perceive giving and receiving peer feedback. DESIGN: We conducted a convergent mixed methods study. In the quantitative component, we randomized residents to receive feedback on home laparoscopic tasks from peers or faculty. We then held an end-of-curriculum, in-person laparoscopic assessment with members from both groups and compared performance on the in-person assessment between the groups. In the qualitative component, we conducted interviews with resident participants to explore experiences with feedback and performance. Three authors coded and rigorously reviewed interview data using a directed content analysis. SETTING: We performed this study at a single tertiary academic institution: the University of California, San Francisco. PARTICIPANTS: We invited 47 junior residents in general surgery, obstetrics-gynecology, and urology to participate, of whom 37 (79%) participated in the home curriculum and 25 (53%) participated in the end-of-curriculum assessment. RESULTS: Residents in the peer feedback group scored similarly on the final assessment (mean 70.7%; SD 16.1%) as residents in the faculty feedback group (mean 71.8%; SD 11.9%) (p = 0.86). Through qualitative analysis of interviews with 13 residents, we identified key reasons for peer feedback's efficacy: shared mental models, the ability to brainstorm and appreciate new approaches, and a low-stakes learning environment. CONCLUSIONS: We found that peer and faculty feedback led to similar performance in basic laparoscopy and that residents engaged positively with peer feedback, suggesting that peer feedback can be used when residents learn basic laparoscopy.

Beyond the Task: Developing a Tool to Measure Workplace Characteristics That Affect Cognitive Load and Learning.

PURPOSE: Educators lack tools to measure the workplace characteristics that learners perceive to affect learning. Without a tool that encompasses the social, organizational, and physical components of workplace learning environments (WLEs), it is challenging to identify and improve problematic workplace characteristics. Using echocardiography WLE, this study developed a tool to measure workplace characteristics that cardiology fellows perceive to affect learning. METHOD: The Workplace-Cognitive Load Tool (W-CLT) was developed, which encompasses 17 items to measure workplace characteristics that could affect perceived cognitive load and learning. Exploratory factor analysis was used to identify the most parsimonious structure. A total of 646 cardiology subspeciality fellows were recruited from 60 cardiology fellowship programs to complete the survey between November 2020 and February 2021. Validity evidence was collected, guided by the unified model of validity. RESULTS: A total of 308 fellows (response rate, 49%) participated in the survey. The most parsimonious structure included 4 factors: (1) workplace-task, (2) workplace-environment, (3) workplace-orientation, and (4) workplace-teaching and feedback. All factors had high reliability (Cronbach α = 0.92, 0.92, 0.96, and 0.94, respectively). Social, organizational, and physical components of WLEs were represented in the items. Workplace-teaching and feedback had moderate negative correlations with workplace-environment (r = -0.41, P < .001) and workplace-orientation (r = -0.36, P < .001). A moderate positive correlation was found between workplace-task and workplace-teaching and feedback (r = 0.42, P < .001). Workplace-task had weak negative correlations with workplace-environment (r = -0.22, P < .001) and workplace-orientation (r = -0.23, P < .001). CONCLUSIONS: The W-CLT measures workplace characteristics that cardiology fellows perceive to affect their learning. The presence of social, organizational, and physical components emphasizes how workplace characteristics can enhance or impede learning. The W-CLT provides a foundation to explore how learning can be optimized in other WLEs.

Multidisciplinary surgical considerations for en bloc resection of sacral chordoma: review of recent advances and a contemporary single-center series.

OBJECTIVE: Contemporary management of sacral chordomas requires maximizing the potential for recurrence-free and overall survival while minimizing treatment morbidity. En bloc resection can be performed at various levels of the sacrum, with tumor location and volume ultimately dictating the necessary extent of resection and subsequent tissue reconstruction. Because tumor resection involving the upper sacrum may be quite destabilizing, other pertinent considerations relate to instrumentation and subsequent tissue reconstruction. The primary aim of this study was to survey the surgical approaches used for managing primary sacral chordoma according to location of lumbosacral spine involvement, including a narrative review of the literature and examination of the authors' institutional case series. METHODS: The authors performed a narrative review of pertinent literature regarding reconstruction and complication avoidance techniques following en bloc resection of primary sacral tumors, supplemented by a contemporary series of 11 cases from their cohort. Relevant surgical anatomy, advances in instrumentation and reconstruction techniques, intraoperative imaging and navigation, soft-tissue reconstruction, and wound complication avoidance are also discussed. RESULTS: The review of the literature identified several surgical approaches used for management of primary sacral chordoma localized to low sacral levels (mid-S2 and below), high sacral levels (involving upper S2 and above), and high sacral levels with lumbar involvement. In the contemporary case series, the majority of cases (8/11) presented as low sacral tumors that did not require instrumentation. A minority required more extensive instrumentation and reconstruction, with 2 tumors involving upper S2 and/or S1 levels and 1 tumor extending into the lower lumbar spine. En bloc resection was successfully achieved in 10 of 11 cases, with a colostomy required in 2 cases due to rectal involvement. All 11 cases underwent musculocutaneous flap wound closure by plastic surgery, with none experiencing wound complications requiring revision. CONCLUSIONS: The modern management of sacral chordoma involves a multidisciplinary team of surgeons and intraoperative technologies to minimize surgical morbidity while optimizing oncological outcomes through en bloc resection. Most cases present with lower sacral tumors not requiring instrumentation, but stabilizing instrumentation and lumbosacral reconstruction are often required in upper sacral and lumbosacral cases. Among efforts to minimize wound-related complications, musculocutaneous flap closure stands out as an evidence-based measure that may mitigate risk.
