Impact of Time Delay on Simulated Operative Video Telementoring: A Pilot Study.

INTRODUCTION: As NASA and private spaceflight companies push forward with plans for missions to cis-lunar and interplanetary space, the risk of surgical emergency increases. At latencies above 500 ms, telesurgery is not likely to be successful, so near-real-time telementoring is a more viable option. We examined the effect of a 700-ms time delay on the performance of first year surgical residents on a simulated task requiring significant feedback from a mentor in a pilot study.METHODS: A simulated surgical task requiring precision and accuracy with built-in error detection was used. Each resident underwent two trials, one with a mentor in the same room and one with the mentor using a teleconference with time delay. Outcomes measured included time to complete task, game pieces successfully removed, number of errors, and scores on the NASA Task Load Index by both mentor and operator. Data were analyzed using paired t-tests.RESULTS: The time delay group removed significantly fewer pieces successfully than the real time group (3.0 vs. 1.6, P = 0.02). There was no difference in the NASA Task Load Index (TLX) scores for the operators between the two groups, but the mentor reported significantly higher scores on Mental Demand (5.6 vs. 12.0, P = 0.04) and Effort (6.2 vs. 11.8, P = 0.05) during the time-delayed trials.DISCUSSION: A 750-ms time delay significantly degraded performance on the task. Though operator TLX scores were not affected, mentor TLX scores indicated significantly increased mental load. Telementoring is viable, but more onerous than in-person mentoring.Kamine TH, Smith BW, Fernandez GL. Impact of time delay on simulated operative video telementoring: a pilot study.

For the People and the Profession.

In 1982 Dean Warren delivered the presidential address "Not for the Profession… For the People" in which he identified substandard surgical residency programs graduating residents who were unable to pass American Board of Surgery exams. Drs. Warren and Shires as members of the independent ACGME began to close the substandard programs in order to improve surgical care for average Americans i.e. "for the people". By 2003 these changes dramatically reduced the failure rate for the ABS exams and trained good surgeons who could operate independently however the residents were on duty for every other or every third night. In 2003 the ACGME mandated duty hour restrictions in order improve resident wellness and improve the training environment for the profession. However, work hour restrictions reduced the time surgical residents spent in the hospital environment primarily when residents had more autonomy and had exposure to emergency cases which degraded readiness for independent practice. Surgical educators in the 2 decades after the work hour restrictions have improved techniques of training so graduates could not only pass the board exams but also be prepared for independent practice. Surgical residency training has improved by both the changes implemented by the independent ACGME in 1981 and by the work hour restrictions mandated in 2003. Five recommendations are made to ensure that Dr Warren's culture of excellence in surgical training continues in an environment that enhances wellbeing of the trainee i.e. "For the People and the Profession".

International Mixed Reality Immersive Experience: Approach via Surgical Grand Rounds.

BACKGROUND: Coronavirus disease 2019 created unintended but significant experiential barriers for surgical learners to interact at the bedside for teaching/case presentations. We hypothesized that an international grand rounds using the Microsoft HoloLens 2 extended reality (XR) headset would create an improved bedside-learning experience compared to traditional grand rounds formats. STUDY DESIGN: From December 2020 to March 2021, the world's first 2 international mixed reality grand rounds events using the HoloLens 2 headset were held, broadcasting transatlantically (between the University of Michigan and the Imperial College of London) bedside rounding experiences on 5 complex surgical patients to an international audience of 325 faculty, residents, and medical trainees. Participants completed pre- and post-event surveys to assess their experience. RESULTS: Of the 325 participants, 267 (80%) completed pre-surveys, and 95 (29%) completed both the pre- and post-surveys. Respondents (average age, 38 y; 44% women, 56% men; 211 US, 56 UK) included 92 (34%) medical students and residents and 175 faculty and staff. In the pre-event survey, 76% had little or no earlier experience with XR devices, and 94% thought implementation of XR into medical curricula was valuable. In the post-survey, 96% thought telerounding using XR technology was important for the current era, and 99% thought the ability to visualize the examination, imaging, and laboratory results at bedside via XR rounding was highly valuable and that this format was superior to traditional grand rounds. CONCLUSIONS: Almost all of the participants in the mixed reality international grand rounds felt the immersive XR experiences-allowing visualization of clinical findings, imaging, and laboratory results at the patient's bedside-were superior to a traditional grand rounds format, and that it could be a valuable tool for surgical teaching and telerounding.

The Quality of Operative Performance Narrative Feedback: A Retrospective Data Comparison Between End of Rotation Evaluations and Workplace-based Assessments.

OBJECTIVE: To describe the quality of operative performance feedback using evaluation tools commonly used by general surgery residency training programs. SUMMARY OF BACKGROUND DATA: The majority of surgical training programs administer an evaluation through which faculty members may rate and comment on trainee operative performance at the end of the rotation (EOR). Many programs have also implemented the system for improving and measuring procedural learning (SIMPL), a workplace-based assessment tool with which faculty can rate and comment on a trainee's operative performance immediately after a case. It is unknown how the quality of narrative operative performance feedback delivered with these tools compares. METHODS: The authors collected EOR evaluations and SIMPL narrative comments on trainees' operative performance from 3 university-based surgery training programs during the 2016-2017 academic year. Two surgeon raters categorized comments relating to operative skills as being specific or general and as encouraging and/or corrective. Comments were then classified as effective, mediocre, ineffective, or irrelevant. The frequencies with which comments were rated as effective were compared using Chi-square analysis. RESULTS: The authors analyzed a total of 600 comments. 10.7% of EOR and 58.3% of SIMPL operative performance evaluation comments were deemed effective (P < 0.0001). CONCLUSIONS: Evaluators give significantly higher quality operative performance feedback when using workplace-based assessment tools rather than EOR evaluations.

Examining the impact of COVID-19 restrictions on the operative volumes of US general surgery residents.

BACKGROUND: In March 2020, the COVID-19 virus global pandemic forced healthcare systems to institute regulations including the cancellation of elective surgical cases, which likely decreased resident operative experience. The objective of this study was to determine whether the COVID-19 pandemic affected operative experiences of US general surgery residents. METHODS: The operative experience of general surgery residents was examined nationally and locally. Aggregate Accreditation Council for Graduate Medical Education (ACGME) case logs for 2018 to 2019 (pre-COVID) and 2019 to 2020 (COVID) graduates were compared using national mean cumulative operative volume for total major and surgeon chief cases. Locally, ACGME case logs were used to analyze the operative experience among residents at a single, academic center. Average operative volumes per month per resident during peak COVID-19 quarantine months were compared with those the previous year. RESULTS: Compared with 2019 graduates, 2020 graduates completed 1.5% fewer total major cases (1055 ± 155 vs 1071 ± 150, P = .011). This was most evident during chief year, with 8.4% fewer surgeon chief cases logged in 2020 compared with 2019 (264 ± 67 vs 289 ± 69, P < .001). Institutional data revealed that during the peak of the pandemic, residents across all levels completed 42.5% fewer total major operations (12 ± 11 vs 20 ± 14, P < .001). This effect was more pronounced among junior residents compared with senior and chief residents. CONCLUSION: The COVID-19 pandemic was associated with decreased resident case volume. The ramifications of the COVID-19 pandemic for operative competency and autonomy should be carefully examined.

Sushruta on human dissection as pre-requisite to surgery / Sushruta sobre la disección humana como requisito previo a la cirugía

SUMMARY: In the western surgical tradition there has been little acknowledgement of the ancient Vedic surgeon Sushruta who initiated many aspects of surgical practice. In his compendium the Sushruta Samhita, Sushruta systematised medicine in various areas. His meticulous knowledge in many branches of medicine is evident. A brilliant surgeon, he developed plastic surgical techniques, types of bandaging, hygiene practices and over one hundred surgical instruments. In this article, I focus on Sushruta's ideas on human dissection as a pre-requisite for surgery, his method of preparation of human cadavers and his anatomical pedagogy. Sushruta pioneered the instruction of cadaveric based anatomical learning which is still being used in medical teaching.

Cirujano brillante, desarrolló técnicas de cirugía plástica, tipos de vendajes, prácticas de higiene y más de cien instrumentos quirúrgicos. El enfoque de este artículo se centra en las ideas de Sushruta sobre la disección humana como requisito previo para la cirugía, su método de preparación de cadáveres humanos y su pedagogía anatómica. Sushruta fue pionero en la instrucción del aprendizaje anatómico basado en cadáveres que todavía se utiliza en la enseñanza médica.

BJS commission on surgery and perioperative care post-COVID-19.

BACKGROUND: Coronavirus disease 2019 (COVID-19) was declared a pandemic by the WHO on 11 March 2020 and global surgical practice was compromised. This Commission aimed to document and reflect on the changes seen in the surgical environment during the pandemic, by reviewing colleagues' experiences and published evidence. METHODS: In late 2020, BJS contacted colleagues across the global surgical community and asked them to describe how severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) had affected their practice. In addition to this, the Commission undertook a literature review on the impact of COVID-19 on surgery and perioperative care. A thematic analysis was performed to identify the issues most frequently encountered by the correspondents, as well as the solutions and ideas suggested to address them. RESULTS: BJS received communications for this Commission from leading clinicians and academics across a variety of surgical specialties in every inhabited continent. The responses from all over the world provided insights into multiple facets of surgical practice from a governmental level to individual clinical practice and training. CONCLUSION: The COVID-19 pandemic has uncovered a variety of problems in healthcare systems, including negative impacts on surgical practice. Global surgical multidisciplinary teams are working collaboratively to address research questions about the future of surgery in the post-COVID-19 era. The COVID-19 pandemic is severely damaging surgical training. The establishment of a multidisciplinary ethics committee should be encouraged at all surgical oncology centres. Innovative leadership and collaboration is vital in the post-COVID-19 era.

Novel method to link surgical trainee performance data to patient outcomes.

BACKGROUND: A significant roadblock in surgical education research has been the inability to compare trainee performance to the outcomes of those surgeons after they enter independent practice. We describe the feasibility of an innovative method to link trainee performance data with patient outcomes. METHODS: We extracted surgeon NPI numbers from Medicare claims data for common general surgery procedures between 2007 and 2017. Next, American Board of Surgery (ABS) trainee performance data was cross-referenced with additional resources to supplement NPI data. The patient and trainee datasets were linked using NPI number and a linkage rate was calculated. RESULTS: We identified 12,952 unique surgeons in the Medicare file. Medicare surgeons were matched with ABS records by NPI number, with 96.2% (n = 12,460) of surgeons linked successfully. CONCLUSIONS: We demonstrated a novel process to link patient outcomes to trainee performance. This innovation can enable future research investigating the relationship between surgical trainee performance and patient outcomes in independent practice.

Policy options for surgical mentoring: Lessons from Zambia based on stakeholder consultation and systems science.

BACKGROUND: Supervision by surgical specialists is beneficial because they can impart skills to district hospital-level surgical teams. The SURG-Africa project in Zambia comprises a mentoring trial in selected districts, involving two provincial-level mentoring teams. The aim of this paper is to explore policy options for embedding such surgical mentoring in existing policy structures through a participatory modeling approach. METHODS: Four group model building workshops were held, two each in district and central hospitals. Participants worked in a variety of institutions and had clinical and/or administrative backgrounds. Two independent reviewers compared the causal loop diagrams (CLDs) that resulted from these workshops in a pairwise fashion to construct an integrated CLD. Graph theory was used to analyze the integrated CLD, and dynamic system behavior was explored using the Method to Analyse Relations between Variables using Enriched Loops (MARVEL) method. RESULTS: The establishment of a provincial mentoring faculty, in collaboration with key stakeholders, would be a necessary step to coordinate and sustain surgical mentoring and to monitor district-level surgical performance. Quarterly surgical mentoring reviews at the provincial level are recommended to evaluate and, if needed, adapt mentoring. District hospital administrators need to closely monitor mentee motivation. CONCLUSIONS: Surgical mentoring can play a key role in scaling up district-level surgery but its implementation is complex and requires designated provincial level coordination and regular contact with relevant stakeholders.

Impact of the COVID-19 pandemic on surgical practice, training, and research in Nigeria.

INTRODUCTION: the rising rate of SARS-CoV-2 infections has caused perceptible strain on the global health system. Indeed, this disease is also a litmus test for the resilience of the structures in the African health system including surgery. Therefore, this study aimed to determine the impact of the COVID-19 pandemic on surgical practice, training and research in Nigeria. METHODS: it was a cross-sectional study conducted over three weeks in Nigeria among doctors in 12 surgery-related specialties. Consenting participants filled a pre-tested online form consisting of 35 questions in 5 sections which assessed demographics, infection control measures, clinical practice, academic training, research program, and future trends. Data were analyzed using Statistical Package for Social Sciences Version 20. RESULTS: a total of 384 respondents completed the form. Their mean age was 38.3 years. Lockdown measures were imposed in the state of practice of 89.0% of respondents. Most participants reported a decrease in patient volume in outpatient clinics (95.5%) and elective operations (95.8%) compared to reports for emergency operations (50.2%). They also noted a decrease in academic training [Bedside teaching (92.1%), seminar presentation (91.1%) and journal presentation (91.8%)] and research (80.5%). Except in bedside teaching, those who had other virtual academic programmes were thrice the number of those who used in-person mode for the events. CONCLUSION: COVID-19 pandemic has caused a significant change in pattern and a decrease in the volume of patients seen by surgeons in their practice as well as a decrease in the frequency of academic programs and research activities in Nigeria.

Team training and surgical crisis management.

Team training and crisis management derive their roots from fundamental learning theory and the culture of safety that burgeoned forth from the industrial revolution through the rise of nuclear energy and aviation. The integral nature of telemedicine to many simulation-based activities, whether to bridge distances out of convenience or necessity, continues to be a common theme moving into the next era of surgical safety as newer, more robust technologies become available.

Surgical data science and artificial intelligence for surgical education.

Surgical data science (SDS) aims to improve the quality of interventional healthcare and its value through the capture, organization, analysis, and modeling of procedural data. As data capture has increased and artificial intelligence (AI) has advanced, SDS can help to unlock augmented and automated coaching, feedback, assessment, and decision support in surgery. We review major concepts in SDS and AI as applied to surgical education and surgical oncology.

Performance assessment using sensor technology.

Over the past 30 years, there have been numerous, noteworthy successes in the development, validation, and implementation of clinical skills assessments. Despite this progress, the medical profession has barely scratched the surface towards developing assessments that capture the true complexity of hands-on skills in procedural medicine. This paper highlights the development implementation and new discoveries in performance metrics when using sensor technology to assess cognitive and technical aspects of hands-on skills.

Human Cadaveric Artificial Lung Tumor-Mimic Training Model.

Introduction: An important phase in surgical training is gaining experience in real human anatomical situations. When a cadaver is available it may complement the various artificial practice models. However, it is often necessary to supplement the characteristics of the cadavers with a simulation of a tumor. Our objective was to develop an easy-to-create, realistic artificial tumor-mimic model for peripheral lung tumor resection practice. Methods: In our work we injected barium sulphate enriched silicone suspension into 10 isolated, non-fixed lungs of human cadavers, through the puncture of the visceral pleura. Four lesions-apical, hilar and two peripheral-were created in each of ten specimens. After fixation CT scans were obtained and analyzed. The implanted tumor-mimics were examined after anatomical preparation and slicing. Also performed CT-guided percutaneous puncture was also performed to create the lesions in situ in two lungs of human cadavers. Results: Analyzing the CT data of 10 isolated lungs, out of 40 lesions, 34 were nodular (85.0%) and in the nodular group five were spiculated (12.5%). Satellite lesions were formed in two cases (5.0%). Relevant outflow into vessels or airway occurred in five lesions (12.5%). Reaching the surface of the lung occured in 11 lesions (27.5%). The tumor-mimics were elastic and adhered well to the surrounding tissue. The two lesions, implanted via percutaneous puncture, both were nodular and one also showed lobulated features. Conclusion: Our artificial tumor-mimics were easy to create, varied in shape and size, and with percutaneous implantation the lesions provide a model for teaching every step of a surgical procedure.

The Biology and Psychology of Surgical Learning.

Surgical education requires proficiency with multiple types of learning to create capable surgeons. This article reviews a conceptual framework of learning that starts with the biological basis of learning and how neural networks encode memory. We then focus on how information can be absorbed, organized, and recalled, discussing concepts such as cognitive load, knowledge retrieval, and adult learning. Influences on memory and learning such as stress, sleep, and unconscious bias are explored. This overview of the biological and psychological aspects to learning provides a foundation for the articles to follow.
