The Society of Black Academic Surgeons membership survey: Insights on demographics, engagement, and opportunities for improvement.

BACKGROUND: The Society of Black Academic Surgeons (SBAS) sought to understand who constitutes its membership and obtain feedback to improve the organization. METHODS: SBAS conducted a 25-question survey amongst members. RESULTS: The response rate was 19 â€‹% (n â€‹= â€‹132/685) with an even gender breakdown (male n â€‹= â€‹64, female n â€‹= â€‹68). The majority identified as Black or African American (85 â€‹%), followed by White (12 â€‹%). Fifty-two percent identified as trainees, while the rest were practicing surgeons specializing in burn/trauma/critical care (19 â€‹%), oncology (19 â€‹%), and general surgery (13 â€‹%). Half joined SBAS within the last 3 years. Satisfaction was reported at a mean of 3.7/5. Lack of awareness (41 â€‹%), time (13 â€‹%), or interest (5 â€‹%) limited committee participation. Networking (83 â€‹%), mentorship/sponsorship/allyship (71 â€‹%), and leadership development (46 â€‹%) were most valued benefits with job boards, webinars, and grants least valuable. CONCLUSION: SBAS is a unique organization uniting both new and lifetime members and opportunities exist to enhance current membership and improve participation.

Advocating for a New Residency Application Process: A Student Perspective.

OBJECTIVE: The COVID-19 pandemic provided an opportunity for surgical residency programs to rethink their methods of evaluating and recruiting candidates. However, the past year has not been seamless, with a soaring number of applications, reports of programs and applicants having difficulty evaluating each other, and an increasingly uneven distribution of interviews among applicants. Consequently, many have called for national changes to the residency application process to address these longstanding concerns. RESULTS: Here, we review the evolving literature and advocate for the permanent adoption of visiting rotations, virtual interviews with a universal release date and data-driven attendance limits, and opportunities for in-person applicant visits. CONCLUSIONS: We believe these changes leverage the strengths of each format, allow for satisfactory bidirectional evaluation, and promote principles of justice, equity, diversity, and inclusion.

Third year medical student knowledge gaps after a virtual surgical rotation.

INTRODUCTION: This study describes perceived knowledge gaps of third-year medical students after participating in a virtual surgical didactic rotation (EMLR) and shortened in-person surgery rotation during the COVID-19 Pandemic. METHODS: Open-ended and Likert questions were administered at the end of the virtual rotation and inperson-surgical rotation to medical students. Three blinded coders identified themes by semantic analysis. RESULTS: 82 students (51% of all MS3s) participated in the EMLR. Semantic analysis revealed gaps in perioperative management (Post-EMLR:18.4%, Post-Inpatient:26.5%), anatomy (Post-EMLR:8.2%, PostInpatient:26.5%). and surgical skills (Post-EMLR: 43.0%, Post-Inpatient: 44.1%). Students also described gaps related to OR etiquette (Post-EMLR: 12.2%, Post-Inpatient: 8.8%) and team dynamics/the hidden curriculum (Post- Inpatient:26.6%). There was a significant improvement in perceived confidence to perform inpatient tasks after completing the inpatient clinical experience (p ≤ 0.01). CONCLUSION: Virtual interactive didactics for cognitive skills development cannot replace a full clinical surgical experience for third-year medical students. Future curricula should address perceived gaps.

Bursting the Hidden Curriculum Bubble: A Surgical Near-Peer Mentorship Pilot Program for URM Medical Students.

The hidden curriculum of unspoken professional expectations negatively impacts medical student interest in surgery. Medical student mentorship and early surgical exposure have been shown to demystify the hidden curriculum. Although residents and faculty play a vital role, near-peer mentorship may aid in uncovering the hidden curriculum and promoting medical student interest in surgery, especially for those learners who are underrepresented in medicine. We developed and implemented a formalized near-peer mentorship program composed of quarterly small group Surgical Peer Teacher led lessons and one-on-one Surgical Support Team mentorship meetings covering surgical curriculum topics for medical students at an academic medical school. This structured near-peer mentorship model provides a mechanism to demystify surgical culture, increase early access to surgical mentorship, and develop mentorship skills amongst students. This program aims to uncover the surgical hidden curriculum to improve surgical career support and interest among medical students with less exposure and access to physician role models. This longitudinal mentorship model is student-run and can be easily adapted to enhance existing support models at medical schools. Future studies will evaluate utilization, impact on surgical specialty interest, and efficacy in demystifying the surgical hidden curriculum.

Common Injury Patterns from Standing Motorized Scooter Crashes.

PURPOSE OF REVIEW: With the rising popularity of standing motorized scooters in major cities in the United States, many hospitals are experiencing a surge of traumatic injuries associated with this new mode of transportation. The impact and characteristics of injuries associated with standing motorized scooters are evolving, and safety regulations for the riders are poorly defined. There is a need for a review for healthcare providers and policy makers on this topic. RECENT FINDINGS: Since its market introduction of rentable standing motorized scooters in late 2017, there has been an exponential rise in emergency department visits and hospitalization due to scooter-related trauma in urban hospitals. There have been a number of independent hospital-based and national-level studies describing demographics and trends of injury patterns in the last 2 years. SUMMARY: Patients presenting to the hospital with injuries tend to be young male between 20 and 40 years of age, presenting at night. Head and extremity injuries are common, and patients often do not comply with helmets and other protective gears. Intoxication is a major risk factor for injuries requiring hospital admission and surgical interventions. These findings increase awareness for (1) healthcare providers to recognize and triage high-energy injuries, and (2) policy makers to advocate universal helmet use, increase public safety education, and enforce road safety regulations to minimize the impact of these injuries.

"Who wants me to do what?" varied expectations from key stakeholder groups in the surgical intensive care unit creates a challenging learning environment.

BACKGROUND: Surgical intensive care units (SICU) require complex care from a multi-disciplinary team. Frequent changes in team members can lead to shifting expectations for junior general surgical trainees, which creates a challenging working and learning environment. We aim to identify expectations of junior surgery trainee's medical knowledge and technical/non-technical skills at the start of their SICU rotation. We hypothesize that expectations will not be consistent across SICU stakeholder groups. METHODS: Twenty-eight individual semi-structured interviews were conducted with six SICU stakeholder groups at a medium-sized academic hospital. Expectations were identified from interview transcripts. Frequency counts were analyzed. RESULTS: Forty-one expectations were identified. 4 expectations were identified by a majority of interviewees. Most expectations were identified by 7 or fewer interviewees. 23 (53%) expectations were shared by at least one stakeholder group. 2 (8%) expectations were shared by all groups. CONCLUSIONS: SICU stakeholder groups identified ten medical knowledge, ten technical skill, and three non-technical skill expectations. Yet, few expectations were shared among the groups. Thus, SICU stakeholder groups have disparate expectations for surgery trainees in our SICU.

Where Do We Go From Here? Assessing Medical Students' Surgery Clerkship Preparedness During COVID-19.

INTRODUCTION: The impact of COVID-19 on surgical education has been profound, and clinical learning experiences transitioned to virtual formats. This study investigated the impact of virtual experiences created to facilitate learning during the pandemic for medical students. METHODS: We performed a cohort study to determine the perceived clinical preparedness for medical students enrolled in the preclinical surgery pilot course, surgical Extended Mastery Learning Rotation (EMLR), and longitudinal surgical clerkship (LC). The preclinical surgery pilot course took place before COVID-19 disruptions, and the EMLR and LC experiences took place virtually. Specialty choice was examined in the EMLR and LC cohorts. Performance on the NBME surgical assessments was analyzed among students enrolled in the traditional clerkship and pandemic-disrupted courses and compared to national data using a two-sample t-test. RESULTS: Compared to preclinical students, EMLR and LC students demonstrated improvements in their perceived surgical clerkship readiness. After the 3-week EMLR course, in the setting of completing only one-third of the clerkship year, students had an average NBME Surgical Self-Assessment Exam score of 72 (SD 12), comparable to the national average of 71 (SD 9) p = 0.33. The average shelf exam score for students (N = 24) enrolled in the traditional clerkship (block 1), prior to COVID-19, disruptions was 66 (SD 9) compared to an average score of 69 (SD 9) for the longitudinal clerkship students (N = 20) that took the shelf exam later in the year (p = 0.36). COVID-19 disruptions did not affect specialty choice. All LC students have decided on a specialty; 50% nonsurgical and 50% surgical. From the EMLR cohort, 36% and 38% plan to pursue surgical and nonsurgical specialties, respectively, with 26% still undecided. CONCLUSIONS: Courses were well-liked and will be implemented in future clerkships. Surgical educators demonstrated flexibility and creativity in the development of the EMLR. Despite COVID-19 disruptions, medical students made progress in their clinical skills and foundational science knowledge. COVID-19 disruptions did not appear to impact specialty choice.

Near-Peer Learning During the Surgical Clerkship: A Way to Facilitate Learning After a 15-Month Preclinical Curriculum.

OBJECTIVES: To investigate the performance and perspectives of third-year medical students (MS3s) participating in near-peer learning (NPL) sessions during their core surgical clerkship following a 15-month preclerkship curriculum. DESIGN: An evaluation study of 7 NPL sessions developed and implemented by fourth-year medical students (MS4s) held from March 2019 to February 2020. MS4s taught 1-2 sessions per rotation that included test taking strategies, illness script development, radiology review, case-based multiple-choice questions, and rapid review. Participants completed a questionnaire with 11 seven-point Likert and open-ended questions after each session. Analyses included quantitative comparison of shelf score averages between NPL participants and nonparticipants and qualitative content analysis for open-ended questions. SETTING: Surgical clerkship at the University of California, San Francisco. PARTICIPANTS: Forty-eight (32%) MS3s participated, with an average attendance of 10 students per rotation. Thirty-three (69%) participants completed the questionnaire. RESULTS: MS3s enjoyed the session (6.9 ± 0.4), improved their knowledge (6.8 ± 0.5), and felt more prepared for the surgery shelf examination (6.5 ± 0.6). MS4 leaders found that MS3s always wanted radiology review, and their interest in test taking strategies and illness script development declined across the clerkship year. Participants had lower shelf exam scores compared to nonparticipants (68.1 vs 71.4, respectively; p = 0.04, ES = 0.03). Shelf exam scores increased over time in both cohorts. Each group had 2 shelf exam failures. Qualitative analysis suggests that MS3s appreciated the NPL's tailored approach and exam demystification, with a desire for increased NPL integration into the clerkship. CONCLUSION: Students participating in NPL were satisfied with the sessions. Participants may have been students who struggled as indicated by shelf exam scores and appreciated the support. The shift in preferred topics across the blocks reflects the students' development during clerkships. Near-peer teachers should adjust sessions over time to fit students' evolving needs.

The spontaneous breathing pattern and work of breathing of patients with acute respiratory distress syndrome and acute lung injury.

BACKGROUND: The spontaneous breathing pattern and its relationship to compliance, resistance, and work of breathing (WOB) has not been examined in patients with acute respiratory distress syndrome (ARDS) or acute lung injury (ALI). Clinically, the ratio of respiratory frequency to tidal volume (f/VT) during spontaneous breathing may reflect adaptation to altered compliance, resistance, and increased WOB. We examined the relationship between f/VT, WOB, and respiratory system mechanics in patients with ARDS/ALI. METHODS: Data from spontaneous breathing trials were collected from 33 patients (20 with ARDS, 13 with ALI) at various points in their disease course. WOB and respiratory system mechanics were measured with a pulmonary mechanics monitor that incorporates Campbell diagram software. Differences between the patients with ARDS and ALI were assessed with 2-sided unpaired t tests. Multivariate linear regression models were constructed to assess the relationship between f/VT and other pulmonary-related variables. RESULTS: Patients with ARDS had significantly lower compliance than those with ALI (24 +/- 6 mL/cm H2O vs 40 +/- 13 mL/cm H2O, respectively, p < 0.001), but this did not translate into significant differences in either WOB (1.70 +/- 0.59 J/L vs 1.43 +/- 0.90 J/L, respectively, p = 0.30) or f/VT (137 +/- 82 vs 107 +/- 49, respectively, p = 0.23). Multivariate linear regression modeling revealed that peak negative esophageal pressure, central respiratory drive, duration of ARDS/ALI, minute ventilation deficit between mechanical ventilation and spontaneous breathing, and female gender were the strongest predictors of f/VT. CONCLUSION: The characteristic rapid shallow breathing pattern in patients with ARDS/ALI occurs in the context of markedly diminished compliance, elevated respiratory drive, and increased WOB. That f/VT had a strong, inverse relationship to peak negative esophageal pressure also may reflect the influence of muscle weakness.

Routine computed tomography after recent operative exploration for penetrating trauma: What injuries do we miss?

BACKGROUND: Patients with penetrating trauma who cannot be stabilized undergo operative intervention without preoperative imaging. In such cases, postoperative imaging may reveal additional injuries not identified during the initial operative exploration. The purpose of this study is to explore the utility of postoperative CT imaging in the setting of penetrating trauma. METHODS: This was a retrospective analysis of patients with penetrating trauma treated at an urban Level 1 trauma center between 2010 and 2015. Patients were included if they underwent an emergent laparotomy without preoperative imaging. Patients were excluded if they had prior imaging or concomitant blunt injury. For the purposes of this study, occult injury was defined as a CT scan finding not mentioned in the first operative report. Descriptive statistics were used to compare patient characteristics who had received imaging immediately postoperatively with those who had not. RESULTS: During the 5-year study period, 328 patients who had a laparotomy for penetrating trauma over the study period, 225 patients met the inclusion criteria. Seventy-three (32%) patients underwent CT scanning immediately postoperatively with occult injuries identified in 38 (52%) patients. The most frequent occult injuries were orthopedic (20 of 43) and genitourinary (9 of 43). Importantly, 10 (26%) of the 38 patients required an intervention for these occult injuries. Those selected for immediate postoperative imaging were more likely to have sustained gunshot wounds and were significantly more severely injured (higher Injury Severity Score and longer length of hospital stay) when compared to patients who did not receive immediate imaging. CONCLUSION: We recommend the use of immediate postoperative CT after emergent laparotomy especially when there is a high index of suspicion for spine or genitourinary injuries and in patients who have sustained ballistic penetrating injuries. LEVEL OF EVIDENCE: Therapeutic/care management, level IV; diagnostic tests or criteria, level IV.

Reconsidering the Resources Needed for Multiple Casualty Events: Lessons Learned From the Crash of Asiana Airlines Flight 214.

IMPORTANCE: To date, a substantial portion of multiple casualty incident literature has focused exclusively on prehospital and emergency department resources needed for optimal disaster response. Thus, inpatient resources required to care for individuals injured in multiple casualty events are not well described. OBJECTIVE: To highlight the resources beyond initial emergency department triage needed for multiple casualty events, using one of the largest commercial aviation disasters in modern US history as a case study. DESIGN, SETTING, AND PARTICIPANTS: Prospective case series of injured individuals treated at an urban level I trauma center following the crash of Asiana Airlines flight 214 on July 6, 2013. This analysis was conducted between June 1, 2014, and December 1, 2015. EXPOSURE: Commercial jetliner crash. MAIN OUTCOMES AND MEASURES: Medical records, imaging data, nursing overtime, blood bank records, and trauma registry data were analyzed. Disaster logs, patient injuries, and blood product data were prospectively collected during the incident. RESULTS: Among 307 people aboard the flight, 192 were injured; 63 of the injured patients were initially evaluated at San Francisco General Hospital and Trauma Center (the highest number at any of the receiving medical facilities; age range, 4-74 years [23 were aged <17 years and 3 were aged >60 years]; median injury severity score of 19 admitted patients, 9 [range, 9-45]), including the highest number of critically injured patients (10 of 12). Despite the high impact of the crash, only 3 persons (<1%) died, including 1 in-hospital death. Among the 63 patients, 32 (50.8%) underwent a computed tomographic imaging study, with imaging of the abdomen and pelvis being the most common. Sixteen of the 32 patients undergoing computed tomography (50.0%) had a positive finding on at least 1 scan. Nineteen patients had major injuries and required admission, with 5 taken directly from the emergency department to the operating room. The most frequent injury was spinal fracture (13 patients). In the first 48 hours, 15 operations were performed and 117 total units of blood products were transfused. A total of 370 nursing overtime hours were required to treat the injured patients on the day of the event. CONCLUSIONS AND RELEVANCE: Proper disaster preparedness requires attention to hospital-level needs beyond initial emergency department triage. The Asiana Airlines flight 214 crash highlights the need to plan for high use of advanced imaging, blood products, operating room availability, nursing resources, and management of inpatient hospital beds.

Work of breathing during lung-protective ventilation in patients with acute lung injury and acute respiratory distress syndrome: a comparison between volume and pressure-regulated breathing modes.

BACKGROUND: Pressure-control ventilation (PCV) and pressure-regulated volume-control (PRVC) ventilation are used during lung-protective ventilation because the high, variable, peak inspiratory flow rate (V (I)) may reduce patient work of breathing (WOB) more than the fixed V (I) of volume-control ventilation (VCV). Patient-triggered breaths during PCV and PRVC may result in excessive tidal volume (V(T)) delivery unless the inspiratory pressure is reduced, which in turn may decrease the peak V (I). We tested whether PCV and PRVC reduce WOB better than VCV with a high, fixed peak V (I) (75 L/min) while also maintaining a low V(T) target. METHODS: Fourteen nonconsecutive patients with acute lung injury or acute respiratory distress syndrome were studied prospectively, using a random presentation of ventilator modes in a crossover, repeated-measures design. A target V(T) of 6.4 + 0.5 mL/kg was set during VCV and PRVC. During PCV the inspiratory pressure was set to achieve the same V(T). WOB and other variables were measured with a pulmonary mechanics monitor (Bicore CP-100). RESULTS: There was a nonsignificant trend toward higher WOB (in J/L) during PCV (1.27 + 0.58 J/L) and PRVC (1.35 + 0.60 J/L), compared to VCV (1.09 + 0.59 J/L). While mean V(T) was not statistically different between modes, in 40% of patients, V(T) markedly exceeded the lung-protective ventilation target during PRVC and PCV. CONCLUSIONS: During lung-protective ventilation, PCV and PRVC offer no advantage in reducing WOB, compared to VCV with a high flow rate, and in some patients did not allow control of V(T) to be as precise.

A Case of Unrecognized Intrathoracic Placement of a Subclavian Central Venous Catheter in a Patient with Large Traumatic Hemothorax.

Traditional recommendations suggest placement of a subclavian central venous catheter (CVC) ipsilateral to a known pneumothorax to minimize risk of bilateral pneumothorax. We present the case of a 65-year-old male with a right hemopneumothorax who was found to have intrathoracic placement of his right subclavian CVC at thoracotomy despite successful aspiration of blood and transduction of central venous pressure (CVP). We thus recommend extreme caution with the interpretation of CVC placement by blood aspiration and CVP measurement alone in patients with large volume ipsilateral hemothorax.

The effects of tidal volume demand on work of breathing during simulated lung-protective ventilation.

BACKGROUND: Lung-protective ventilation (LPV) can result in a ventilator tidal volume (V(T)) below patient V(T) demand, which may elevate work of breathing (WOB). Increasing the ventilator inspiratory flow may not sufficiently reduce WOB, because the patient's flow-time requirements may exceed the ventilator's flow-time delivery pattern. We investigated (1) the effects of V(T) demand on WOB during LPV and (2) which ventilator pattern best reduced WOB while achieving LPV goals. METHODS: A standard WOB lung model simulated assisted breathing. Using 3 ventilators (Hamilton Veolar, Hamilton Galileo, and Dräger Evita 2 dura), we tested volume-control ventilation with a constant flow pattern (VCV-CF), volume-control ventilation with a decelerating flow (VCV-DF), and pressure-control ventilation (PCV). Simulated V(T) demand was increased from 50-125% of the ventilator-delivered V(T) (400 mL) as ventilator inspiratory time (T(I)) was decreased (0.95, 0.80, 0.65, and 0.45 s) relative to simulated T(I) (0.8 s). WOB was measured with a pulmonary mechanics monitor. RESULTS: During VCV-CF and VCV-DF, a V(T) demand of > or = 100% drastically increased WOB, attributable to imposed WOB from the inspiratory valve. Increasing inspiratory flow by using the decelerating flow pattern and/or decreasing T(I) reduced WOB, but generally not to normal levels. "Double-triggered" breaths, with excessive V(T) delivery, often occurred when ventilator T(I) was well below simulated T(I). PCV was most effective in reducing WOB, but V(T) delivery exceeded the LPV target unless T(I) was reduced. CONCLUSIONS: Given our dual goals of reducing both WOB and V(T) during LPV, VCV-DF with relatively brief T(I) appeared to be the best option, followed by PCV with a relatively brief T(I).

Discussion of medical errors in morbidity and mortality conferences.

CONTEXT: Morbidity and mortality conferences in residency programs are intended to discuss adverse events and errors with a goal to improve patient care. Little is known about whether residency training programs are accomplishing this goal. OBJECTIVE: To determine the frequency at which morbidity and mortality conference case presentations include adverse events and errors and whether the errors are discussed and attributed to a particular cause. DESIGN, SETTING, AND PARTICIPANTS: Prospective survey conducted by trained physician observers from July 2000 through April 2001 on 332 morbidity and mortality conference case presentations and discussions in internal medicine (n = 100) and surgery (n = 232) at 4 US academic hospitals. MAIN OUTCOME MEASURES: Frequencies of presentation of adverse events and errors, discussion of errors, and attribution of errors. RESULTS: In internal medicine morbidity and mortality conferences, case presentations and discussions were 3 times longer than in surgery conferences (34.1 minutes vs 11.7 minutes; P =.001), more time was spent listening to invited speakers (43.1% vs 0%; P<.001), and less time was spent in audience discussion (15.2% vs 36.6%; P<.001). Fewer internal medicine case presentations included adverse events (37 [37%] vs 166 surgery case presentations [72%]; P<.001) or errors causing an adverse event (18 [18%] vs 98 [42%], respectively; P =.001). When an error caused an adverse event, the error was discussed as an error less often in internal medicine (10 errors [48%] vs 85 errors in surgery [77%]; P =.02). Errors were attributed to a particular cause less often in medicine than in surgery conferences (8 [38%] of 21 medicine errors vs 88 [79%] of 112 surgery errors; P<.001). In discussions of cases with errors, conference leaders in both internal medicine and surgery infrequently used explicit language to signal that an error was being discussed and infrequently acknowledged having made an error. CONCLUSIONS: Our findings call into question whether adverse events and errors are routinely discussed in internal medicine training programs. Although adverse events and errors were discussed frequently in surgery cases, teachers in both surgery and internal medicine missed opportunities to model recognition of error and to use explicit language in error discussion by acknowledging their personal experiences with error.

American College of Surgeons/Association for Surgical Education medical student simulation-based surgical skills curriculum needs assessment.

BACKGROUND: Simulation can enhance learning effectiveness, efficiency, and patient safety and is engaging for learners. METHODS: A survey was conducted of surgical clerkship directors nationally and medical students at 5 medical schools to rank and stratify simulation-based educational topics. Students applying to surgery were compared with others using Wilcoxon's rank-sum tests. RESULTS: Seventy-three of 163 clerkship directors (45%) and 231 of 872 students (26.5%) completed the survey. Of students, 28.6% were applying for surgical residency training. Clerkship directors and students generally agreed on the importance and timing of specific educational topics. Clerkship directors tended to rank basic skills, such as examination skills, higher than medical students. Students ranked procedural skills, such as lumbar puncture, more highly than clerkship directors. CONCLUSIONS: Surgery clerkship directors and 4th-year medical students agree substantially about the content of a simulation-based curriculum, although 4th-year medical students recommended that some topics be taught earlier than the clerkship directors recommended. Students planning to apply to surgical residencies did not differ significantly in their scoring from students pursuing nonsurgical specialties.
