  • A 20-year review of surgical training case logs: Is general surgery still general? Surgery Kearse, L. E., Zeineddin, A., Schmiederer, I. S., Korndorffer, J. R., Lau, J. N. 2021


    BACKGROUND: Surgical training has undergone many facets of restructuring over the most recent decades, with critiques of the quality and variability of training as well as the competency of recent graduates. This study examines the changes in surgical training in operative volume and breadth in the past 2 decades.METHODS: The Accreditation Council for Graduate Medical Education Case Log Statistics Reports from 1999 to 2019 were reviewed. Case logs were grouped into defined case categories and group levels of postgraduate training. Descriptive analyses and multiple linear regressions were performed.RESULTS: General surgery residents are graduating with 10.7% more cases, owing to increases in mostly junior year cases (P < .001). The breadth of specialty cases has decreased, while there was an increase in alimentary and abdominal cases to 58.4% from 47.2% 20 years ago. A decrease in vascular surgery cases from 19.9% to 10.7% of all cases was noted. Analysis of the distribution of defined categories showed right skewness in many categories with mode being much lower than reported mean.CONCLUSION: Evaluation of trends, despite residents graduating with higher case volume than the minimum required, shows that the breadth and variety of cases has narrowed significantly in the past 20 years, providing a case for general surgery training restructuring.

    BACKGROUND: Given the multifaceted nature of operating room teams, miscommunication at various perioperative stages leads to lapses in teamwork and communication, which potentiates adverse events. In situ interprofessional operating room simulations are a valuable tool in identifying the possible threats to patient safety in the operating room. Participant confidence may also increase; however, perceived confidence in specific areas of team communication in the clinical environment remains unclear. This research aims to study how in situ interprofessional operating room simulations increase participants' individual confidence in 4 team principles derived from crisis resource management: using effective communication, utilizing resources, establishing role clarity, and using effective situational awareness.METHODS: Over a 2-year period, interdisciplinary operating room team members were assigned to participate in 13 simulated surgical case scenarios, which were chosen based on the volunteer surgeon's specialty. These cases were designed to engage all team members and included a crisis scenario (ie, hemorrhage, airway emergency, arrhythmia, or cardiac arrest). All statistical analyses were performed using RStudio version 1.2.1335 software. We analyzed matched pre- and postsimulation self-assessment of individual confidence using the Wilcoxon signed-rank test for each of the 4 aforementioned constructs of interest derived from crisis resource management training principles. Significance was set at P < .0038, using Bonferroni correction, for all comparisons to account for the multiple comparisons problem.RESULTS: There was a statistically significant shift in the 4-point scale toward greater self-reported confidence from presimulation to postsimulation for each of the 4 team principles: using effective communication (P= .0019, r= 0.18), utilizing resources well (P= .0014, r= 0.18), establishing role clarity (P < .0010, r= 0.22), and using effective situational awareness (P < .0010, r= 0.27).CONCLUSION: In this pilot study, we describe how teaching crisis resource management principles in an in situ operative simulation is an effective way to increase the confidence of communication skills among the members of an interdisciplinary procedure/operative team during crisis scenarios. In situ simulation can be used to evaluate system competence and interdisciplinary dynamics, and to identify latent conditions that predispose to medical error. As we continue to conduct these sessions, we aim to evaluate their impact on individual confidence and the advancement of interdisciplinary efforts to improve patient care.

  • A Generalizable Multimodal Scrub Training Curriculum in Surgical Sterile Technique. MedEdPORTAL : the journal of teaching and learning resources Anderson, T. N., Hasty, B. N., Schmiederer, I. S., Miller, S. E., Shi, R., Aalami, L. R., Huffman, E. M., Choi, J. N., Lau, J. N. 2021; 17: 11077


    Introduction: Recent endeavors from governing bodies such as the AAMC have formally recognized the importance of aseptic technique. AAMC guidelines include activities that all graduating physicians should be able to perform with minimum indirect supervision and were developed to recognize these needs. For example, the skills necessary for aseptic technique include daily safety habits and general physician procedures.Methods: We developed a scrub training curriculum and evaluated the program through a quasi-experimental study with a pre- and posttest design. Questions were developed to examine students' perceived knowledge and skills as related to the objectives of the course and to their anxieties, concerns, and future training needs.Results: Between February 2020 and March 2020, 44 students completed the curriculum. Students indicated that self-efficacy significantly increased in all aspects of the curricular goals following curriculum completion. Students identified understanding OR etiquette as the most anxiety-provoking element associated with scrub training. They felt that more time could be spent elucidating this etiquette. On the other hand, tasks such as surgical hand hygiene were the least anxiety-inducing.Discussion: We share this multimodal scrub training curriculum, mapped to the AAMC's guidelines, to reduce variability in teaching strategies and skills acquisition through a standardized curriculum. Also, we effectively imparted these skills and instilled a sense of confidence in learners as they worked to provide their best in patient care and safety.

  • COVID-19 Impact on Surgical Resident Education and Coping. The Journal of surgical research Wise, C. E., Bereknyei Merrell, S. n., Sasnal, M. n., Forrester, J. D., Hawn, M. T., Lau, J. N., Lin, D. T., Schmiederer, I. S., Spain, D. A., Nassar, A. K., Knowlton, L. M. 2021; 264: 534–43


    Healthcare systems and surgical residency training programs have been significantly affected by the novel coronavirus disease 2019 (COVID-19) pandemic. A shelter-in-place and social distancing mandate went into effect in our county on March 16, 2020, considerably altering clinical and educational operations. Along with the suspension of elective procedures, resident academic curricula transitioned to an entirely virtual platform. We aimed to evaluate the impact of these modifications on surgical training and resident concerns about COVID-19.We surveyed residents and fellows from all eight surgical specialties at our institution regarding their COVID-19 experiences from March to May 2020. Residents completed the survey via a secure Qualtrics link. A total of 38 questions addressed demographic information and perspectives regarding the impact of the COVID-19 pandemic on surgical training, education, and general coping during the pandemic.Of 256 eligible participants across surgical specialties, 146 completed the survey (57.0%). Junior residents comprised 43.6% (n = 61), compared to seniors 37.1% (n = 52) and fellows 19.3% (n = 27). Most participants, 97.9% (n = 138), anticipated being able to complete their academic year on time, and 75.2% (n = 100) perceived virtual learning to be the same as or better than in-person didactic sessions. Participants were most concerned about their ability to have sufficient knowledge and skills to care for patients with COVID-19, and the possibility of exposure to COVID-19.Although COVID-19 impacted residents' overall teaching and clinical volume, residency programs may identify novel virtual opportunities to meet their educational and research milestones during these challenging times.

  • Preclinical Surgical Preparatory Course and the NRMP Match: Early Exposure and Surgical Recruitment a 10-Year Follow-Up. Journal of surgical education Anderson, T. N., Shi, R., Schmiederer, I. S., Miller, S. E., Lee, E. W., Hasty, B. N., Lin, D. T., Lau, J. N. 2020


    OBJECTIVE: Many medical students mentally commit to specialties prior to entering clerkships. This is why early preclinical interactions with surgical specialties, through mentorship and/or interest groups, increases the opportunity to nurture enthusiasm for surgery. In 2007, a course providing preclinical medical students with introductory surgical skills training and preparation for the surgical environment ("SURG205") was established at our institution. The course underwent a major revision in 2016, increasing intraoperative mentorship by matching students to surgical attendings and requiring students to scrub into operative cases together. We anticipate that the positive surgical experiences created by the course will lead to further development and enhancement of student interest in surgical specialties-interest that we hypothesized would reflect in their National Resident Matching Program (NRMP) Match outcomes.DESIGN: NRMP results from 2010 to 2019 were cross-referenced with a database of students who participated in the SURG205 course from 2007 to 2016. With this, we examined the correlation between student participation in SURG205 and surgical specialty match. Descriptive statistics were used to review the trends of the NRMP results, and Pearson's correlation was used to determine the relationship and its significance.SETTING: This study was conducted in a single private medical school in California.PARTICIPANTS: Specialties considered "surgical" included: General Surgery, integrated programs-such as Plastic, Thoracic, or Vascular surgery, Obstetrics and Gynecology, Orthopedic Surgery, Otolaryngology, Neurosurgery, and Urology. All other specialties were considered nonsurgical. Students identified as having participated in SURG205 and who then also took part in the NRMP.RESULTS: Seven hundred eighty students underwent the Match process from 2010 to 2019. 144 (18.5%) of these students participated in SURG205 between 2007 and 2016. Each Match class ranged in size from 62 to 91 (median = 77.5, IQR = 14.5) students. (Table 1) Two-hundred and nineteen students (28.1%) matched into a surgical specialty, of which 34 (15.5%) selected general surgery. From 2010 to 2019 the rate of students who matched into surgical specialties averaged 28.1% per year with a slight nonstatistically significantly increasing trend over that time period R2 = 0.30 (p = 0.09; Fig. 1). There was a significant increase in trend in proportion of students who took the course and matched into any specialty between 2010 and 2019 (R2 = 0.85, p = 0.0002; Fig. 2). And, there was a statistically significant positive relationship between students taking the course and matching into a surgical specialty (R2 = 0.63, p = 0.01; Fig. 3).CONCLUSION: Our results highlight the increasing tendency of students who pursue surgical specialties having previously participated in this early exposure courses. Not only is student interest created and encouraged through positive mentorship experiences, but that interest may be associated with increases in application rates and eventual match into the specialty. General surgery training programs might consider these trends when designing courses to ease transitions into first-year residency positions-such as fourth-year surgical boot camps, surgical procedure-based anatomy courses, and mentorship frameworks. This information further justifies the cost and time commitment required to administer these programs for students.

  • Operating Room In Situ Interprofessional Simulation for Improving Communication and Teamwork. The Journal of surgical research Shi, R. n., Marin-Nevarez, P. n., Hasty, B. n., Roman-Micek, T. n., Hirx, S. n., Anderson, T. n., Schmiederer, I. n., Fanning, R. n., Goldhaber-Fiebert, S. n., Austin, N. n., Lau, J. N. 2020; 260: 237–44


    Effective teamwork and communication are correlated with improved patient care quality and outcomes. The belief that each team member contributes to excellent patient care in the operating room (OR) leads to a more productive work environment. However, poor teamwork and communication lead to poorer OR outcomes. We qualitatively and quantitatively explored perspectives of three OR professions (nursing, anesthesiology, and surgery) on teamwork and communication in the OR preinterprofessional and postinterprofessional in situ OR simulation.One-on-one semi-structured interviews were conducted; 14 pre-in situ simulations during July-October 2017 (three surgery, four anesthesiology, and six nursing staff), and 10 post-in situ simulations during August-November 2017 (five surgery, four anesthesiology, and one nursing staff). Themes were identified inductively to create a codebook. The codebook was used to consensus code all interviews. This analysis informed the development of a quantitative survey distributed to all contactable interviewees (22).Presimulation and postsimulation interview participants concurred on teamwork and communication importance, believed communication to be key to effective teamwork, and identified barriers to communication: lack of cordiality, lack of engagement from other staff, distractions, role hierarchies, and lack of familiarity with other staff. The large majority of survey participants-all having participated in simulations-believed they could use effective communication in their workplace.Establishing methods for improving and maintaining the ability of OR professionals to communicate with each other is imperative for patient safety. Effective team communication leads to safe and successful outcomes, as well as a productive and supportive OR work environment.

  • Defining the Deficit in US Surgical Training: The Trainee's Perspective. Journal of the American College of Surgeons Anderson, T. N., Payne, D. H., Dent, D. L., Kearse, L. E., Schmiederer, I. S., Korndorffer, J. R. 2020


    Self-efficacy (SE) is the personal judgement of how well one can successfully complete a task. The goal of this study is to assess SE of PGY5 residents for common general surgery operations. We hypothesize there are deficits in SE of PGY5 residents, and SE of a given operation correlates with 1) experience performing the operation without attending assistance (independently) and/or 2) teaching the operation start-to-finish.A survey was linked to the 2020 ABSITE. From the ACGME case log's 15 most commonly performed surgeon-chief operations and AHRQ's 15 most common operations, 10 operations were selected. Residents evaluated their ability to perform these operations independently using a 5-point SE scale. Residents were asked if they had experience performing these operations independently and/or teaching the operation start-to-finish. Descriptive statistics and Pearson correlation were used to examine the relationship between SE and operative experience.1145 of 1367 (84%) PGY5 residents responded. Highest SE was in performing wide-local excision (90.24%) and the lowest in performing open thyroidectomy (19.58%) (Table 1). Eighty-eight (7.7%) reported SE in all procedures. Statistically significant positive correlations were identified between experience and SE for cases performed without assistance (r = 0.98, p<0.01) and cases taught (r = 0.91, p<0.01).With 5 months left in training, 92.3% of residents report deficits in preparation for practice as defined by SE to complete common procedures independently. Resident SE increased in direct relation to performed cases and cases taught.
