Ankle fracture surgery performed by orthopaedic residents without supervision has comparable outcomes to surgery performed by fellowship trained orthopaedic surgeons.

BACKGROUND: Unstable fractures often necessitate open reduction and internal fixation (ORIF), which generally yield favourable outcomes. However, the impact of surgical trainee autonomy on healthcare quality in these procedures remains uncertain. We hypothesized that surgery performed solely by residents, without supervision or participation of an attending surgeon, can provide similar outcomes to surgery performed by trauma or foot and ankle fellowship-trained orthopaedic surgeons. METHODS: A single-center cohort of an academic level-1 trauma center was retrospectively reviewed for all ankle ORIF between 2015 and 2019. Data were compared between surgery performed solely by post-graduate-year 4 to 6 residents, and surgery performed by trauma or foot and ankle fellowship-trained surgeons. Demographics, surgical parameters, preoperative and postoperative radiographs, and primary (mortality, complications, and revision surgery) and secondary outcome variables were collected and analyzed. Univariate analysis was performed to evaluate outcomes. RESULTS: A total of 460 ankle fractures were included in the study. Nonoperative cases and cases operated by senior orthopaedic surgeons who are not trauma or foot and ankle fellowship-trained orthopaedic surgeons were excluded. The average follow-up time was 58.4 months (SD ± 12.5). Univariate analysis of outcomes demonstrated no significant difference between residents and attendings in complications and reoperations rate (p = 0.690, p = 0.388). Sub-analysis by fracture pattern (Lauge-Hansen classification) and the number of malleoli involved and fixated demonstrated similar outcomes. surgery time was significantly longer in the resident group (p < 0.001). CONCLUSION: The current study demonstrates that ankle fracture surgery can be performed by trained orthopaedic surgery residents, with similar results and complication rates as surgery performed by fellowship-trained attendings. These findings provide valuable insights into surgical autonomy in residency and its role in modern clinical training and surgical education. LEVEL OF EVIDENCE: Level III - retrospective cohort study.

Patellar Fracture Surgery Performed Autonomously by Residents, Yields Similar Short-Term Outcomes to Surgery Performed by Fellowship-Trained Surgeons.

BACKGROUND: Open reduction and internal fixation are the gold-standard treatment for displaced patellar fractures. The current literature remains inconclusive on the relationship between resident participation in the operating room and optimal patient outcomes. We hypothesize that surgeries performed solely by residents, without attending supervision, can provide similar outcomes to those performed by fellowship-trained orthopedic surgeons, providing new insights into the relationship between resident autonomy and surgical outcomes in the field of orthopedic trauma. METHODS: A tertiary trauma center cohort was retrospectively reviewed for all surgically treated patellar fractures between 2015 and 2020. The cohort was divided into 2 groups: patients operated by residents and patients operated by orthopedic trauma specialists. Demographics, surgical parameters, and radiographs were compared between the groups to evaluate complications and reoperation rates, radiographic outcomes (such as hardware failure, or loss of reduction), and clinical outcomes (including residual pain, painful hardware, decreased range of motion, and infections). RESULTS: A total of 129 patellar fractures were included in the study. Demographics and ASA were similar between the groups. There were no significant differences in complications (p = 0.900) or reoperation rates (p = 0.817), with an average follow-up time of 8 months (SD ± 5.3). Residents had significantly longer surgery duration (p =0.002). However, the overall length of stay was shorter in the resident group (p < 0.001). CONCLUSION: The study shows patellar fracture surgery performed by adequately trained residents can provide similar outcomes to those performed by fellowship-trained orthopaedic trauma surgeons. These findings highlight the significance of surgical autonomy in residency and its role in contemporary surgical education.

Identifying barriers to resident robotic console time in a general surgery residency through a targeted needs assessment.

Robotic-assisted general surgery is experiencing exponential growth. Despite our institution's high volume, residents often graduate with inadequate console experience. Our aim was to identify the educational needs of residents and perceived barriers to residents' console time from both attendings and residents. Separate surveys were created and distributed to robotic surgery faculty and general surgery residents at our institution. Questions were a variety of modalities and focused on the robotic surgery experience at our institution, including barriers to resident console time from both attending surgeon and resident perspectives. Although residents' interest in robotic surgery exceeded that of open and laparoscopic surgery, confidence in their robotic skills was low compared to the other modalities. The top barriers to participating in robotic cases according to residents included minimal or no previous console time with the attending, lack of simulator time, and being required to perform bedside assistant duties. Faculty reported resident preparedness, prior robotic skill demonstration, simulator time, case complexity, and their own confidence as significant factors influencing resident console time. Using these results, we concluded that the design and implementation of a formal robotic surgery curriculum should incorporate simulation-based opportunities for residents to practice their skills, improve confidence, and increase console experience. In addition, simulation opportunities for faculty should also be considered to allow for improvement and maintenance of robotic surgical skills.

Unveiling the Economic Toll of Surgical Learning Curve in Elderly Hip Fractures.

Can the financial impact of implant choice during the learning curve of inexperienced surgeons in hip fracture surgery be quantified? Hip fractures in the elderly are a significant medical concern, often requiring surgical interventions performed by orthopedic surgery residents. As healthcare costs rise, exploring cost reduction opportunities within the healthcare system becomes crucial. In this prospective analysis, we examined the financial implications of implant choices encountered by residents during their learning curve in hip fracture surgery. Our study included 278 surgically treated pertrochanteric fractures using the same locking cephalomedullary nail. Data on patients, surgeons (including their experience and seniority), and all implants charged by the hospital were collected. This encompassed documentation of any nail-related equipment that was opened on the operating table and whether it was subsequently used by the end of the procedure. By calculating the number and cost of these implants, we assessed the financial burden associated with suboptimal choices made during the learning curve. Our findings revealed that in 16.18% of surgeries, instances of suboptimal implant utilization occurred, highlighting the complexities of the learning process. Importantly, the rate of these challenges was not influenced by surgeon seniority or patient characteristics. The mean additional cost per surgery was determined to be USD 65.69 ± 157.63 for surgeries with suboptimal implant utilization, compared to USD 56.55 ± 139.13 for surgeries without such challenges. Although there was a trend towards higher implant-related costs in resident-led surgeries, the difference did not reach statistical significance. These findings underscore the feasibility of enabling residents to autonomously perform intramedullary nailing surgeries, even without specialist supervision, while incurring minimal additional expenses during the learning curve. By acknowledging the financial implications associated with the learning curve in the management of hip fractures, we can strive to optimize healthcare costs, thus addressing an important aspect of this issue.

Improving the resident assessment process: application of App-based e-training platform and lean thinking.

BACKGROUND: The assessment system for standardized resident training is crucial for developing competent doctors. However, it is complex, making it difficult to manage. The COVID-19 pandemic has also aggravated the difficulty of assessment. We, therefore, integrated lean thinking with App-based e-training platform to improve the assessment process through Define-Measure-Analyze-Improve-Control (DMAIC) cycles. This was designed to avoid unnecessary activities that generate waste. METHODS: Panels and online surveys were conducted in 2021-2022 to find the main issues that affect resident assessment and the root causes under the frame of waste. An online app was developed. Activities within the process were improved by brainstorming. Online surveys were used to improve the issues, satisfaction, and time spent on assessment using the app. RESULTS: A total of 290 clinical educators in 36 departments responded to the survey, and 153 clinical educators used the online app for assessment. Unplanned delay or cancellation was defined as the main issue. Eleven leading causes accounted for 87.5% of the issues. These were examiner time conflict, student time conflict, insufficient examiners, supervisor time conflict, grade statistics, insufficient exam assistants, reporting results, material archiving, unfamiliarity with the process, uncooperative patients, and feedback. The median rate of unplanned delay or cancellation was lower with use of the app (5% vs 0%, P < 0.001), and satisfaction increased (P < 0.001). The median time saved by the app across the whole assessment process was 60 (interquartile range 60-120) minutes. CONCLUSIONS: Lean thinking integrated with an App-based e-training platform could optimize the process of resident assessment. This could reduce waste and promote teaching and learning in medical education.

Cost analysis of training residents in robotic-assisted surgery.

INTRODUCTION: Use of robotic-assisted surgery is increasing, and resident involvement may lead to higher costs. We investigated whether senior resident involvement in noncomplex robotic cholecystectomy (RC) and inguinal hernia (RIH) would take more time and cost more when compared to non-robotic cholecystectomy (NRC) and inguinal hernia repair (NRIH). METHODS: We extracted surgery duration and total cost of NRC, NRIH, RC, and RIH from 7/2016 to 6/2020 with senior resident (PGY4-5) involvement. We excluded complex cases as well as prisoner cases and those with new faculty and research residents. We assessed differences between robotic and non-robotic cases in surgery duration and total cost per minute, using one-way ANOVA. RESULTS: We included 1608 cases (non-robotic 1145 vs. robotic 463). On average, RC cases with a senior resident took less time than NRC (179.4 < 185.8, p = 0.401); surgery duration of RIH cases was similar with NRIH cases. The total cost per minute of RC cases with a senior resident on average was $9.30 higher than NRC cases for each minute incurred in the operating room but did not lead to a significant change in overall cost. RIH cases, on the other hand, cost less per minute than NRIH cases (114.1 < 126.5, p = 0.399). CONCLUSION: Training in robotic surgery is important. Noncomplex RC and RIH involving senior residents were not significantly longer nor did they incur significantly more cost than non-robotic procedures. Senior resident training in noncomplex robotic surgery can be efficient and can be included in the residency curriculum.

Clinical training within an Indigenous community: a qualitative description of pediatric residents' learning experiences.

Objectives: Indigenous children and families experience inequities across health domains. Calls to action from the Truth and Reconciliation Commission of Canada and the Indigenous Physicians Association of Canada have highlighted the need for medical professionals to better understand these inequities and improve the provision of culturally safe services through collaboration between Indigenous communities and medical residency programs. There are currently no published evaluations of clinical training for Canadian medical residents within Indigenous communities. The current study was conducted at an on-reserve pediatric outreach clinic (Maskwacis Pediatric Outreach Clinic; MPOC). Methods: From the perspectives of pediatric residents, the researchers explored the impacts of attending MPOC during resident training. Residents completed anonymous surveys over an 18-month period that addressed patient and caregiver encounters, the value of MPOC on resident training, significant pediatric health issues in the community, and limitations of MPOC in contributing to training. Seven residents participated in a focus group that expanded upon survey results. Results: Thirty-four surveys were completed. Responses reflected an enhanced understanding of social, environmental, and systemic contributors to health issues, and learning regarding the complexity of circumstances that Indigenous children and families face. Focus group results were organized into the impacts of MPOC on (1) residents and (2) patients, with several sub-categories. Conclusions: Findings suggest that direct clinical exposure to Indigenous child health issues is a valuable educational experience for pediatric residents. The importance of strength-based approaches to educating medical residents regarding the social determinants of health and colonial contexts of Indigenous health disparities is also identified.

Telementoring Feasibility Using a Novel Low-cost Lazy Glass Microsurgical Simulator: A "Proof of Concept" Experimental Study.

BACKGROUND: In order to mitigate the challenges in microsurgical skill acquisition and training, especially in the COVID-19 era, we devised a novel microsurgical telementoring protocol for imparting microsurgical skill training in a socially distanced setting. We objectively analyzed its feasibility among neurosurgical trainees. METHODS: In a controlled experimental design, 8 residents at different stages of their tenure participated in a lazy glass microsurgical simulator-based telementoring exercise. Microsuturing with 4-0 silk, 10-0 nylon on silastic sheets, and eggshell peeling tasks were performed by the residents prior to and after a telementoring session by a panel of 4 neurosurgical experts. Impact of telementoring was assessed in terms of surgical accuracy, efficiency, and dexterity by providing objective (Performance score [PS]), subjective (Neurosurgery Education and Training School [NETS] score), and cumulative scores (CS). Subgroup analysis was performed to assess the impact at different stages of residency. RESULTS: PS, NETS score, and CS were significantly improved by telementoring sessions for 10-0 nylon micro-suturing (P < 0.001), and egg-hell peeling tasks (P < 0.01). PS and CS improved significantly (P = 0.01) after telementoring sessions for 4-0 silk microsuturing. Both pre- and post-training CS were similar across the 2 subgroups PGY 1-4 and PGY 5-6 (P > 0.05). CONCLUSIONS: Telementoring is a viable alternative for neurosurgical resident training in the COVID-19 era, where reduction in elective surgeries and social distancing norms preclude conventional teaching. Lazy glass microsurgical simulator-based structured telementoring protocol is a cost-effective tool to augment surgical proficiency and finesse, irrespective of stage of residency.

Assessment of training and selected factors on speed and quality of performing different tasks on the endoscopic simulator.

INTRODUCTION: One of the most significant challenges nowadays is to educate and predict the predispositions of young surgeons taking into consideration that every ability has its own learning curve. AIM: To determine the influence of selected factors and examine the shape and the length of the learning curve in performing simple tasks on an endoscopic simulator. MATERIAL AND METHODS: Twenty students took part in 4 training sessions with a one-week break between sessions. They were training 12 min and performed three tasks at every session on the endoscopic simulator. To identify whether selected factors influence the time of completing tasks, the participants were asked to fill in questionnaires. All participants also completed the Minnesota Manual Dexterity Test (MMDT) to assess hand-eye coordination. RESULTS: Our research reveals that regardless of activities performed in free time, the shape of the learning curve was logarithmic. Improvement after the fourth session ranged from 50% to 75%. Performing specific activities in the free time did not influence the results achieved on the simulator. No statistically significant correlation between MMDT results and the time to accomplish each task was found. CONCLUSIONS: This study has shown that the length of the learning curve of performing simple tasks is quite short and the shape is logarithmic. It suggests that more complex exercises should be included in the training programme.

Efficiency of Increasing Prospective Resident Entrustment in the Operating Room.

BACKGROUND: Prospective resident entrustment (i.e., trust an attending surgeon intends to give to a resident in the near future) in the operating room (OR) closely associates with granted future autonomy. However, the process of determining resident entrustment takes time and effort. Thus, this study aimed to assess the efficiency of granting incremental resident entrustment for upcoming surgical cases. METHODS: We analyzed prospective resident entrustment of 6 chief residents in 76 cases of laparoscopic cholecystectomy, laparoscopic colectomy, ventral hernia, and inguinal hernia scored by attending surgeon, resident, and a surgeon observer. Matched direct costs and operative time were extracted from hospital billing. We assessed the efficiency of granting incremental prospective resident entrustment with direct cost per minute incurred in the evaluated case. Effect size was computed to assess the differences between groups. RESULTS: Sixty-three cases (82.9%) were matched; 47.6% (30/63) of matched cases received prospective resident entrustment score ≥ 4. The direct cost per minute increased in three procedures (laparoscopic cholecystectomy, laparoscopic colectomy, and ventral hernia) with increased intention of granting incremental resident entrustment. Inguinal hernia was the only procedure in which chiefs were entrusted with future independence while the direct cost per minute decreased. CONCLUSIONS: Our findings demonstrate more time and effort are required (except for inguinal hernia) for residents to be entrusted with increased independence in the future. Faculty and resident development programs are recommended to improve the efficiency of the process of granting incremental operative entrustment to optimize resident training quality and cost of care delivery.

Development and evaluation of a low-cost part-task trainer for laparoscopic repair of inguinal hernia in boys and the acquisition of basic laparoscopy skills.

PURPOSE: To examine the fidelity of our model of laparoscopic inguinal hernia repair (LIHR) in boys and evaluate its value in resident training programs and the learning of basic laparoscopy skills. METHODS: We created a simulation model with inexpensive, easy-to-obtain equipment. Study participants from 34 university hospital departments received a user manual and an evaluation questionnaire (11 items rated on a 5-point Likert scale). We considered that the evaluation was positive when the median overall score was 4 or over. We compared the results for residents (n=26) vs. expert surgeons (n=29) (t tests). RESULTS: The duration of the procedure was significantly longer among the residents (30.0±16.8 min) than among the expert surgeons (20.5±11.7 min; p=0.01). In both groups, the participants rated the model favorably with regard to the overall impression (median score: 4.0±1.0), realism (4.0±0.9), ease of access to the required equipment (5.0±0.6), the quality of the user manual (5.0±0.6), ease of assembly (5.0±0.8), ease of the procedure (5.0±0.8), value in resident training programs (4.0±0.9), and value in learning basic laparoscopy skills (5.0±0.8)). The evaluation was positive (4.0±0.9). CONCLUSION: Our low-cost model was an effective teaching and training tool for LIHR and basic laparoscopy skills. LEVEL OF EVIDENCE: Level IV.

"POMELO PROJECT" - a simple and low cost simulator for harvesting skin graft by plastic surgery residents.

BACKGROUND: Harvesting partial thickness skin grafts is an important technical skill the training plastic surgeon is required to hone. Historically accomplished via manual dermatome (Humby's knife) or the modern day electric dermatome. OBJECTIVE: Presenting a means of practicing the use of Humby's knife for novice surgeons. METHODS: 15 plastic surgeons comprising 8 seniors and 7 residents, in a single tertiary center participated. Each utilised a Humby knife to harvest 4 skin grafts from a Pomelo. The graft areas were measured via computerised image processing, comparing measures of graft harvest consistency across groups of surgeons. RESULTS: In the resident surgeon group, the average relative difference between exact graft area and encompassing area was 0.45, as compared with 0.15 in the Senior surgeon group, indicating a greater degree of inconsistency in graft harvest. Comparisons across groups yielded significant differences per each of the 4 grafts harvested (p <=0.005). LIMITATIONS: single center and small cohort (inherent to the sparsity of plastic surgeons), marginal statistical evidence. CONCLUSIONS: Citrus Maxima (Pomelo) is a useful substrate to instruct and practice the use of Humby knife effectively, allowing novice surgeons to practice the manual manoeuvres required therefore as well as increase confidence in its subsequent operative use.

Low-cost 3D print-based phantom fabrication to facilitate interstitial prostate brachytherapy training program.

PURPOSE: The purpose of this study was to manufacture a realistic and inexpensive prostate phantom to support training programs for ultrasound-based interstitial prostate brachytherapy. METHODS AND MATERIALS: Five phantom material combinations were tested and evaluated for material characteristics; Ecoflex 00-30 silicone, emulsion silicone with 20% or 50% mineral oil, and regular or supersoft polyvinyl chloride (PVC). A prostate phantom which includes an anatomic simulated prostate, urethra, seminal vesicles, rectum, and normal surrounding tissue was created with 3D-printed molds using 20% emulsion silicone and regular and supersoft PVC materials based on speed of sound testing. Needle artifact retention was evaluated at weekly intervals. RESULTS: Speed of sound testing demonstrated PVC to have the closest ultrasound characteristics of the materials tested to that of soft tissue. Several molds were created with 3D-printed PLA directly or cast on 3D-printed PLA with high heat resistant silicone. The prostate phantom fabrication workflow was developed, including a method to produce dummy seeds for low-dose-rate brachytherapy practice. A complete phantom may be fabricated in 1.5-2 h, and the material cost for each phantom was approximated at $23.98. CONCLUSIONS: A low-cost and reusable phantom was developed based on 3D-printed molds for casting. The proposed educational prostate phantom is an ideal cost-effective platform to develop and build confidence in fundamental brachytherapy procedural skills in addition to actual patient caseloads.

The prevalence and effects of on-call stepdown on orthopaedic registrar training: the North West trainees' perspective.

INTRODUCTION: Safe staffing levels are increasingly being threatened by gaps in rotas. When a gap occurs in junior grade on-call rotas the orthopaedic registrar needs to step down and undertake the role of both junior and middle-grade doctor. This increased responsibility could compromise the safety and wellbeing of patients and doctors. This study quantifies the prevalence and effects for trainees of stepdown while on call. MATERIALS AND METHODS: An anonymous online and paper survey of trainees was conducted. The primary outcomes were the prevalence of stepdown in trainees' experience, the effects of stepdown on trainees and patients, and the overall impact on training and morale. RESULTS: The response rate was 93% (n = 51). Of the total, 55% of trainees had experienced stepdown, which occurred a minimum of 84 times, statistically more frequently for expected absences rather than unexpected absences (p = 0.002). Of the trainees who stepped down, 64% felt pressure to do so from seniors and 79% from hospital management. Some 50% of trainees felt that step down was managed in an unsafe manner; 40% of trainees stated that stepdown impacted on their own personal safety and 50% of trainees lost a training opportunity. Overall, 57% of trainees considered that stepdown and rota gaps affected their morale negatively. In 85% of cases there were no issues that resulted in patient harm. CONCLUSION: The survey results suggest that stepdown is common and it does impact negatively upon registrar training, safety and morale. Patient safety overall seems to be well protected.

Incorporating Sex and Gender into Culturally Competent Simulation in Medical Education.

Background and Objectives: Simulation provides a vehicle to introduce sex and gender competent training into the education of medical trainees. Materials and Methods: Using the previously validated Texas Tech University Health Sciences Center Sex and Gender Specific Health PubMed Advanced Search Tool, we reviewed the existing sex- and gender-based medical simulation education literature. A single article specifically addressed the incorporation of sex- and gender-based medicine in the development of simulation-based training. The Society for Academic Emergency Medicine Sex and Gender Interest Group then collaboratively developed recommendations for the incorporation of these concepts into simulation training. Results: Collaboratively developed recommendations were as follows. Knowledge-based competency in sex- and gender-based medicine involves understanding the relevant key terminology. Attitude-based competencies include an understanding of tendencies toward bias in patient assessment and care, which can be addressed in the self-reflection component of a simulation debrief. Skill-based competencies include communication skills, assessing the social context in which a patient is pursuing medical care, and recognition of gender-based cultural models of health and disease. Successful implementation includes specific faculty development, administrative and financial resources, gender-specific simulation equipment and selection of standardized patients, and scenarios that address sex- and gender-based medical care. Conclusion: The adoption of sex and gender competent simulation has the potential to significantly impact medical training and the provision of empathetic and humanistic care while reducing sex- and gender-based health care disparities.

Content counts, but context makes the difference in developing expertise: a qualitative study of how residents learn end of shift handoffs.

BACKGROUND: Handoff education is both formal and informal and varies widely across medical school and residency training programs. Despite many efforts to improve clinical handoffs, little evidence has shown meaningful improvement. The objective of this study was to identify residents' perspectives and develop a deeper understanding on the necessary training to conduct safe and effective patient handoffs. METHODS: A qualitative study focused on the analysis of cognitive task interviews targeting end-of-shift handoff experiences with 35 residents from three geographically dispersed VA facilities. The interview data were analyzed using an iterative, consensus-based team approach. Researchers discussed and agreed on code definitions and corresponding case examples. Grounded theory was used to analyze the transcripts. RESULTS: Although some residents report receiving formal training in conducting handoffs (e.g., medical school coursework, resident boot camp/workshops, and handoff debriefing), many residents reported that they were only partially prepared for enacting them as interns. Experiential, practice-based learning (i.e., giving handoffs, covering night shift to match common issues to handoff content) was identified as the most suited and beneficial for delivering effective handoff training. Six skills were described as critical to learning effective handoffs: identifying pertinent information, providing anticipatory guidance, applying acquired clinical knowledge, being concise, incorporating delivery strategies, and appreciating the styles/preferences of handoff recipients. CONCLUSIONS: Residents identified the immersive performance and the experience of covering night shifts as the most important aspects of learning to execute effective handoffs. Formal education alone can miss the critical role of real-time sense-making throughout the process of handing off from one trainee to another. Interventions targeting senior resident mentoring and night shift could positively influence the cognitive and performance capacity for safe, effective handoffs.

Perspectives from a Residency Training Program Following the Implementation of a Wellness Initiative.

BACKGROUND AND OBJECTIVES: Programs that address overall wellbeing early in residency are necessary to prevent physician burnout and promote physician mental health to improve patient outcomes and ensure long and productive careers. A wellness initiative was implemented at our institution 3 years ago. We present feedback from participating residents across all levels of training. METHODS: A 17-question survey was administered to resident physicians in the department of neurosurgery at our institution. In addition to the resident survey results, we obtained personal perspective pieces from attendings and residents across all levels of training. RESULTS: A total of 8 resident physicians completed a 17-question survey. 100% of participants felt that health and wellness initiatives are "very important" for resident physicians, that the initiative has been "largely positive" for the department overall, and that is has positively impacted their personal life in addition to their professional life. The majority (75%) of respondents indicated that participation has not affected patient care responsibilities "at all." CONCLUSIONS: Participating resident perceptions of the wellness program are highly favorable. The survey results, combined with the perspectives across training levels, provide insight for other programs wishing to implement program of their own.

Low-cost endoscopic third ventriculostomy simulator with mimetic endoscope.

OBJECTIVE Hydrocephalus affects approximately 1 in 500 people in the US, yet ventricular shunting, the gold standard of treatment, has a nearly 85% failure rate. Endoscopic third ventriculostomy (ETV) is an alternative surgical approach for a specific subset of hydrocephalic patients, but can be limited by the inability of neurosurgical residents to practice prior to patient contact. The goal of this study was to create an affordable ETV model and endoscope for resident training. METHODS Open-source software was used to isolate the skull and brain from the CT and MR images of a 2-year-old boy with hydrocephalus. A 3D printer created the skull and a 3D mold of the brain. A mixture of silicone and silicone tactile mutator was used to cast the brain mold prior to subsequent compression and shearing modulus testing. A mimetic endoscope was then created from basic supplies and a 3D printed frame. A small cohort of neurosurgical residents and attending physicians evaluated the ETV simulator with mimetic endoscope. RESULTS The authors successfully created a mimetic endoscope and ETV simulator. After compression and shearing modulus testing, a silicone/Slacker ratio between 10:6 and 10:7 was found to be similar to that of human brain parenchyma. Eighty-seven percent of participants strongly agreed that the simulator was useful for resident training, and 93% strongly agreed that the simulator helped them understand how to orient themselves with the endoscope. CONCLUSIONS The authors created an affordable (US$123, excluding 3D printer), easy-to-use ETV simulator with endoscope. Previous models have required expensive software and costly operative endoscopes that may not be available to most residents. Instead, this attempt takes advantage of open-source software for the manipulation and fabrication of a patient-specific mold. This model can assist with resident development, allowing them to safely practice use of the endoscope in ETV.

Prevalence, management, and outcome of problem residents among neurosurgical training programs in the United States.

OBJECTIVE: The challenging nature of neurosurgical residency necessitates that appropriate measures are taken by training programs to ensure that residents are properly progressing through their education. Residents who display a pattern of performance deficiencies must be identified and promptly addressed by faculty and program directors to ensure that resident training and patient care are not affected. While studies have been conducted to characterize these so-called "problem residents" in other specialties, no current data regarding the prevalence and management of such residents in neurosurgery exist. The purpose of this study was to determine the rate and the outcome of problem residents in US neurosurgical residency programs and identify predictive risk factors that portend a resident's departure from the program. METHODS: An anonymous nationwide survey was sent to all 108 neurosurgical training programs in the US to assess a 20-year history of overall attrition as well as the management course of problem residents, including the specific deficiencies of the resident, management strategies used by faculty, and the eventual outcome of each resident's training. RESULTS: Responses were received from 36 centers covering a total of 1573 residents, with the programs providing a mean 17.4 years' worth of data (95% CI 15.3-19.4 years). The mean prevalence of problem residents among training programs was 18.1% (95% CI 14.7%-21.6%). The most common deficiencies recognized by program directors were poor communication skills (59.9%), inefficiency in tasks (40.1%), and poor fund of medical knowledge (39.1%). The most common forms of program intervention were additional meetings to provide detailed feedback (93.9%), verbal warnings (78.7%), and formal written remediation plans (61.4%). Of the identified problem residents whose training status is known, 50% graduated or are on track to graduate, while the remaining 50% ultimately left their residency program for other endeavors. Of the 97 residents who departed their programs, 65% left voluntarily (most commonly for another specialty), and 35% were terminated (often ultimately training in another neurosurgery program). On multivariable logistic regression analysis, the following 3 factors were independently associated with departure of a problem resident from their residency program: dishonesty (OR 3.23, 95% CI 1.67-6.253), poor fund of medical knowledge (OR 2.54, 95% CI 1.47-4.40), and poor technical skill (OR 2.37, 95% CI 1.37-4.12). CONCLUSIONS: The authors' findings represent the first study to characterize the nature of problem residents within neurosurgery. Identification of predictive risk factors, such as dishonesty, poor medical knowledge, and/or technical skill, may enable program directors to preemptively act and address such deficiencies in residents before departure from the program occurs. As half of the problem residents departed their programs, there remains an unmet need for further research regarding effective remediation strategies.

The impact of a head and neck microvascular fellowship program on otolaryngology resident training.

OBJECTIVE: To assess the impact of a microvascular head and neck (H&N) fellowship on senior residents' surgical experience. STUDY DESIGN: Retrospective review of Accreditation Council for Graduate Medical Education-generated operative case log reports, retrospective chart review, and electronic survey. METHODS: A retrospective review of one institution's residents' H&N operative case logs and free flap operative reports was performed to determine changes in key indicator cases (KICs) after the addition of a H&N fellowship. An electronic survey was distributed to senior residents at all U.S. otolaryngology residency programs to determine residents' perceptions of a H&N fellow's impact on their surgical experience. An electronic survey was distributed to senior medical students applying to surgical residencies to explore the perceived impact that a fellowship has on the desirability of a residency program. RESULTS: The average number of each postgraduate year (PGY)5's H&N KIC before and after the addition of the fellowship were: parotidectomy, 19 versus 17.8; neck dissection, 33.2 versus 40.6; oral cavity resection, 15.3 versus 12.6; thyroid/parathyroid, 45.5 versus 45.6; and flaps/grafts, 56.7 versus 42. PGY5 participation as first assistant in free flaps dropped from 78% to 17%; however, residents still participated in some aspect of 45% of the cases. Seventy percent of senior residents reported a positive perception of the H&N fellow on their H&N operative experience. Eighty-nine percent of senior medical student respondents reported a nonnegative perception of a fellowship in their applied field. CONCLUSION: The addition of a H&N fellowship did not decrease senior residents' H&N KIC, and most senior residents at programs with fellowships report that the fellow has a positive impact on their H&N operative experience.
