[Training of Academic Neurosurgeons: Current Status and Challenges in Japan].

The concept of translational research, which emphasizes the importance of applying research findings to clinical practice, was first introduced in the early 21st century. Since then, Japan has actively promoted translational research through government and academic institutions, fostering collaboration between basic scientists and clinicians. Despite this, Japan's academic competitiveness has declined globally, particularly in fields such as neurosurgery, due to unique training systems and reduced time for research and education amidst physician work reforms. Herein, we discuss the significance of academic pursuits among clinicians, particularly in Japan's neurosurgery landscape, alongside future challenges.

International Hackathon as a Tool to Augment Education, Collaboration, and Innovation in Global Neurosurgery.

BACKGROUND AND OBJECTIVES: Health care providers' exposure to global surgical disparities is limited in current nursing and/or medical school curricula. For instance, global health is often associated with infectious diseases or maternal health without acknowledging the growing need for surgical care in low- and middle-income countries (LMICs). We propose an international virtual hackathon based on neurosurgical patient cases in under-resourced settings as an educational tool to bring awareness to global surgical disparities and develop relationships among trainees in different countries. METHODS: Participants were recruited through email listservs, a social media campaign, and prize offerings. A 3-day virtual hackathon event was administered, which included workshops, mentorship, keynote panels, and pitch presentations to judges. Participants were presented with real patient cases and directed to solve a barrier to their care. Surveys assessed participants' backgrounds and event experience. The hackathon was executed through Zoom at Harvard Innovation Lab in Boston, MA, on March 25 to 27, 2022. Participants included medical students, with additional participants from business, engineering, or current health care workers. RESULTS: Three hundred seven applications were submitted for 100 spots. Participants included medical students, physicians, nurses, engineers, entrepreneurs, and undergraduates representing 25 countries and 82 cities. Fifty-one participants previously met a neurosurgeon, while 39 previously met a global health expert, with no difference between LMIC and high-income countries' respondents. Teams spent an average of 2.75 hours working with mentors, and 88% of postevent respondents said the event was "very" or "extremely conducive" to networking. Projects fell into 4 categories: access, language barriers, education and training, and resources. The winning team, which was interdisciplinary and international, developed an application that analyzes patient anatomy while performing physical therapy to facilitate remote care and clinical decision-making. CONCLUSION: An international virtual hackathon can be an educational tool to increase innovative ideas to address surgical disparities in LMICs and establish early collaborative relationships with medical trainees from different countries.

How neurosurgeons maintain and update their professional knowledge in a self-directed learning context.

BACKGROUND: Given the changes in the current learning environment health professionals are facing major challenges to keep up with current and updated information with the rapidly growing clinical and scientific knowledge base. Being able to identify relevant, high-quality articles, adapt or adopt to new learning strategies with an already intense workload are just a few of the main challenges. Self-directed learning is a key skill of competent health professionals and describes the process by which individuals evaluate their learning needs, goals and the resources needed for learning, however the emerging problems for professionals practicing SDL are manifold. DESIGN: A qualitative, exploratory approach based on four research questions was used to understand how skilled neurosurgeons maintain and update their professional knowledge. Twenty-six neurosurgeons within the University Hospital of Bern completed a semi-structured interview. RESULTS: One of the main findings concerns the differences between neurosurgeons regarding the SDL strategies they employ, which is compounded by their level of experience. All participants recognized that new or alternative learning approaches are necessary to manage the learning landscape, and for many this concerned their use of learning digital tools. Many, however, were unsure how to change their current behavior. CONCLUSION: The results highlight that positive factors influencing SDL in the workplace include learning leadership and support in identifying new or alternative strategies, an internal culture committed to learning as well as digital learning tools and networks. All are vital in managing the continuously evolving learning environment.

"Now What Do I Do?" - Practical Challenges Faced By Young Neurosurgeons in their Career Management.

Neurosurgical residency is tough. Grueling hours and tough decisions require a mental makeup unlike many other specialties. But the real examination begins after the residency is over. Many young neurosurgeons are faced with a daunting task of deciding their future as soon as they step out of the medical school. Sometimes, such decisions can shape the entire career of the neurosurgeon. However, over the many years of academic teaching and learning what we are not taught is how to "Manage." Management of careers, decision making, and understanding the business end of our profession is lacking. Here, we review the career and decisions needed to be taken by a young neurosurgeon through the glass of a business management mindset. We try to define the opportunities and decisions and how they may reflect on the general population and patients as a whole.

Which Theory of Cerebrospinal Fluid Production and Absorption Do Neurosurgeons Teach to Medical Students? Survey from Medical Universities in Japan, 2022.

Several new studies have been conducted on cerebrospinal fluid (CSF) dynamics. Our educational guidelines, the Model Core Curriculum for Medical University, recommend access to the best current information. However, we do not know whether or when to introduce changes to this concept.We surveyed which theory of CSF dynamics taught to students by neurosurgeons. The old theory is the bulk flow theory, and the new theory explains that CSF is produced from the choroid plexus and capillaries; CSF then pulsates and drains into the venous and lymphatic systems through newly discovered pathways.Old and new theories were taught to 64.8% and 27.0% of students, respectively. The reason for teaching the old theory was to help them understand the pathogenesis of noncommunicating hydrocephalus (77.1%), whereas the reason for teaching the new theory was to teach the latest knowledge (40.0%). Physicians who wished to teach the new theory in the near future accounted for 47.3%, which was higher than those who would teach the new theory in 2022 (27.0%), and those who still wished to teach the old theory in the near future accounted for 43.2%.An education policy on CSF dynamics will be established when we interpret ventricular enlargement and its improvement by third ventriculostomy in noncommunicating hydrocephalus based on the new theory. The distributed answers in the survey shared that it is difficult to teach about CSF dynamics and provided an opportunity to discuss these issues.

Strengthening neurosurgical training programs in Sub-saharan Africa: a medical student's perspective.

This article provides a nuanced exploration of the state and exigencies of neurosurgical training in sub-Saharan Africa (SSA), viewed through the discerning lens of a medical student.

The insufficiency of neurosurgeons, facilities, and training centers, particularly in remote areas, exacerbates this predicament. The imperative to fortify neurosurgical training programs is underscored, necessitating a multifaceted approach inclusive of international collaborations and innovative strategies. The challenges impeding neurosurgical training program implementation range from constrained infrastructure to faculty shortages and financial constraints. Recommendations encompass infrastructural investments, faculty development initiatives, and augmented community engagement. An exploration of neurosurgical training programs across diverse African regions reveals commendable strides and imminent deficits, warranting heightened international collaboration. Furthermore, technological innovations, including virtual reality, robotics, and artificial intelligence, are posited as transformative conduits for augmenting neurosurgical training in SSA. The article concludes with a sagacious compendium of recommendations, encompassing standardized curricula, mentorship paradigms, and stringent evaluation mechanisms, all combining efficaciously fortifying neurosurgical insight in SSA and producing transformative improvements in healthcare outcomes.

Successful adaptation of twinning concept for global neurosurgery collaborations-a validation study.

INTRODUCTION: Globally, many regions have an urgent, unmet need of neurosurgical care. A multi-step neurosurgical twinning technique, International Neurosurgical Twinning Modeled for Africa (INTIMA), was proved to be successful during a previous mission to Neurosurgical Unit, Enugu, Nigeria. The Swedish African Neurosurgical Collaboration (SANC) performed a developmental mission together with the local neurosurgical unit in The Gambia, adopting the INTIMA model. METHODS: A multidisciplinary team visited for a 2-week collaborative mission at the Neurosurgical Department of the Edward Francis Small Teaching Hospital in Banjul, The Gambia. The mission followed the data of neurosurgical operations during and after the mission as well as about the operations 3 months prior to and after the mission was collected. RESULTS: During the mission, a total of 22 operations was carried out, the most common being degenerative spinal conditions (n = 9). In the 3 months following the mission, 43 operations were performed compared to 24 during the 3 months leading up to the mission. The complexity of the performed procedures increased after the mission. An operating microscope (Möller-Wedel) was donated and installed and the neurosurgeons on site underwent training in microneurosurgery. The surgical nurses, nurses at the postoperative ward, and the physiotherapists underwent training. A biomedical engineer serviced multiple appliances and devices improving the patient care on site while training local technicians. CONCLUSION: This study validated the use of the INTIMA model previously described in a mission by Swedish African Neurosurgical Collaboration (SANC). The model is sustainable and produces notable results. The core strength of the model is in the multidisciplinary team securing all the aspects and steps of the neurosurgical care. Installation of an operating microscope opened for further microsurgical possibilities, improving the neurosurgical care in The Gambia.

Evaluating the learning curve of endoscopic surgery for spontaneous intracerebral hemorrhage: A single-center experience in a county hospital.

BACKGROUND: Endoscopic surgery has shown promise in treating Spontaneous Intracerebral Hemorrhage (sICH), but its adoption in county-level hospitals has been hindered by the high level of surgical expertise required. METHODS: In this retrospective study at a county hospital, we utilized a Cumulative Sum (CUSUM) control chart to visualize the learning curve for two neurosurgeons. We compared patient outcomes in the learning and proficient phases, and compared them with expected outcomes based on ICH score and ICH functional outcome score, respectively. RESULTS: The learning curve peaked at the 12th case for NS1 and the 8th case for NS2, signifying the transition to the proficient stage. This stage saw reductions in operation time, blood loss, rates of evacuation < 90 %, rebleeding rates, intensive care unit stay, hospital stay, and overall costs for both neurosurgeons. In the learning stage, 6 deaths occurred within 30 days, less than the 10.66 predicted by the ICH score. In the proficient stage, 3 deaths occurred, less than the 15.88 predicted. In intermediate and high-risk patients by the ICH functional outcome score, the proficient stage had fewer patients with an mRS ≥ 3 at three months than the learning stage (23.8 % vs. 69.2 %, P = 0.024; 40 % vs. 80 %, P = 0.360). Micromanipulating bipolar precision hemostasis and aspiration devices in the endoport's channels sped up the transition from learning to proficient. CONCLUSION: The data shows a learning curve, with better surgical outcomes as surgeons gain proficiency. This suggests cost benefits of surgical proficiency and the need for ongoing surgical education and training in county hospitals.

Neurosurgery Residents' Satisfaction Toward Their Saudi Training Program: Insights from a National Survey.

BACKGROUND: Given the high-stakes nature of their work, neurosurgery residents face constant pressure and require high-quality training to succeed. We aim to investigate the satisfaction levels of residents with their Saudi Neurosurgery Residency Training Program (SNRTP) and its influential factors. METHODS: This is a nationwide, cross-sectional study that employed a questionnaire, structured based on the relevant literature, which was disseminated to neurosurgery residents, commencing from December 2021 and culminating in September 2022. RESULTS: A total of 70 out of 143 neurosurgery residents were included, giving a response rate of 48.9%. Most participants (62.9%) aged 24-28 years old, 55.7% were males, and 40.0% were from the Central region of Saudi Arabia. The residents were further divided into juniors (R1-R3; 64.3%) and seniors (R4-R6; 35.7%). Approximately 13.3% of the juniors were satisfied with the SNRTP, whereas only 8.0% of the seniors were satisfied. Dissatisfaction rates over the SNRTP were significantly higher in the seniors (68.0%) compared to the juniors (28.9%; P = 0.006). The frequency of operating room sessions per week and presence of protected research time were the only 2 factors significantly associated with the junior and senior residents' satisfaction, respectively. CONCLUSIONS: The SNRTP has a vision to provide the society with elite competent neurosurgeons. However, we found a degree of dissatisfaction among the residents, indicating a need for improving the SNRTP's policies. We recommend incorporating more hands-on training opportunities, implementing a mentorship model, setting tailored teaching sessions, and establishing resident wellness programs. We hope this study initiate dialogue on promoting residents' satisfaction and overall well-being.

Pediatric neurosurgery training during residency in Switzerland and the need for dedicated subspecialization training.

INTRODUCTION: Pediatric Neurosurgery as a subspeciality started to emerge during the late 1950s, with only a few dedicated pediatric neurosurgeons in the Western world. Over the last few decades, the awareness that children require subspecialized care by dedicated pediatric neurosurgeons and an interdisciplinary team has been growing worldwide, leading to an increase in pediatric neurosurgeons. Several studies have shown that subspecialized care for pediatric patients improves outcomes and is cost-effective. This survey aims to assess the current setting of pediatric neurosurgery and training of neurosurgical residents in pediatric neurosurgery in Switzerland. METHODS: We conducted an online survey by sending e-mail invitations in 2021 to all neurosurgical residents in Switzerland. The survey included questions regarding the participants' demographics, current workplace structures, the care of specific pediatric neurosurgical pathologies, and participants' opinions of the Swiss training program for pediatric neurosurgery and possible improvement. We defined at the beginning of the survey that a pediatric neurosurgeon is a board-certified neurosurgeon with at least one year of dedicated pediatric neurosurgical fellowship training abroad. RESULTS: We received a total of 25 responses from residents, of which 20 (80%) were male. Twenty-two participants (88%) worked in one of seven major hospitals in Switzerland at the time of the survey, and four (16%) were interested in pursuing a fellowship in pediatric neurosurgery. Seven (35%) and five residents (25%) feel comfortable taking care on the ward of a craniosynostosis and hydrocephalus patient younger than 6 months, respectively. Twelve residents (60%) feel comfortable taking care of a pediatric brain tumor patient. The majority (n = 22, 88%) of all residents agree that a fellowship-trained pediatric neurosurgeon should treat children, while two (8%) residents state that any neurosurgeon with an interest in pediatric neurosurgery should be able to treat children. All residents (n = 25, 100%) agree that pediatric neurosurgery training and care in Switzerland needs to be improved. CONCLUSION: Pediatric neurosurgery training in Switzerland is rather heterogeneous and not very well structured, with varying frequencies of children-specific neurosurgical pathologies. Most residents agreed that a subspecialized pediatric neurosurgeon should oversee the care of children in neurosurgery, while all agree that pediatric neurosurgical training and care should be improved in Switzerland.

The Impact of Colonialism on Surgical Training Structures in Africa Part 1: Contextualizing the Past, Present, and Future.

Since the first African country attained independence from colonial rule, surgical training on the continent has evolved along 3 principal models. The first is a colonial, local master-apprentice model, the second is a purely local training model, and the third is a collegiate intercountry model. The 3 models exist currently and there are varied perceptions of their relative merits in training competent neurosurgeons. We reviewed the historical development of training and in an accompanying study, seek to describe the complex array of surgical training pathways and explore the neocolonial underpinnings of how these various models of training impact today the development of surgical capacity in Africa. In addition, we sought to better understand how some training systems may contribute to the widely recognized "brain drain" of surgeons from the African continent to high income countries in Europe and North America. To date, there are no published studies evaluating the impact of surgical training systems on skilled workforce emigration out of Africa. This review aims to discover potentially addressable sources of improving healthcare and training equity in this region.

Neurosurgery Training in Greece.

OBJECTIVE: The structure and specifics of neurosurgery residency training vary substantially across programs and countries, potentially leading to differences in clinical reasoning, surgical skills, and professionalism. The Greek neurosurgical training system is unique in numerous respects. This manuscript delineates the current state of neurosurgical residency training in Greece and outlines future directions. METHODS: A narrative review was conducted to describe the Greek neurosurgical residency training structure. The perspectives of the authors regarding challenges in training and future directions were synthesized. RESULTS: This manuscript describes the neurosurgery residency curriculum and board certification process, existing training programs, and key challenges in neurosurgery residency training in Greece. The authors propose future directions to reform neurosurgical training in Greece. CONCLUSIONS: Neurosurgery residency training in Greece has been largely unchanged for many years. This review leads to suggested modification of the existing training process may improve the quality of training and equip neurosurgeons to respond to the rapidly changing landscape of the field.

A patient-specific, interactive, multiuser, online mixed-reality neurosurgical training and planning system.

OBJECTIVE: Mixed-reality simulation is an emerging tool for creating anatomical models for preoperative planning. Its use in neurosurgical training (NT) has been limited because of the difficulty in real-time interactive teaching. This study describes the development of a patient-specific, interactive mixed-reality NT system. The authors took cases of intracranial tumor resection or neurovascular compression (NVC) as examples to verify the technical feasibility and efficacy of the mixed-reality NT system for residents' training and preoperative planning. METHODS: This study prospectively enrolled 40 patients who suffered from trigeminal neuralgia, hemifacial spasms, or intracranial tumors. The authors used a series of software programs to process the multimodal imaging data, followed by uploading the holographic models online. They used a HoloLens or a standard iOS device to download and display the holographic models for training. Ten neurosurgical residents with different levels of surgical experience were trained with this mixed-reality NT system. Change in surgical strategy was recorded, and a questionnaire survey was conducted to evaluate the efficacy of the mixed-reality NT system. RESULTS: The system allows the trainer and trainee to view the mixed-reality model with either a HoloLens or an iPad/iPhone simultaneously online at different locations. Interactive manipulation and instant updates were able to be achieved during training. A clinical efficacy validation test was conducted. The surgeons changed their exploration strategy in 48.3% of the NVC cases. For residents with limited experience in surgery, the exploration strategy for 75.0% of all patients with NVC was changed after the residents were trained with the mixed-reality NT system. Of the 60 responses for intracranial tumors, the trainee changed the surgical posture in 19 (31.7%) cases. The change of the location (p = 0.0338) and size (p = 0.0056) of craniotomy are significantly related to the experience of the neurosurgeons. CONCLUSIONS: The mixed-reality NT system is available for local or real-time remote neurosurgical resident training. It may effectively help neurosurgeons in patient-specific training and planning of surgery for cases of NVC and intracranial tumor. The authors expect the system to have a broader application in neurosurgery in the near future.

Neurosurgical Education in Tanzania: The Dar es Salaam Global Neurosurgery Course.

BACKGROUND: Postgraduate neurosurgical training is essential to develop a neurosurgical workforce with the skills and knowledge to address patient needs for neurosurgical care. In Tanzania, the number of neurosurgeons and neurosurgical services offered have expanded in the past 40 years. Training opportunities within the country, however, are not sufficient to meet the needs of residents, specialists, and nurses in neurosurgery, forcing many to train outside the country incurring associated costs and burdens. We report on the Dar es Salaam Global Neurosurgery Course, which aims to provide local training to neurosurgical health care providers in Tanzania and surrounding countries. METHODS: We report the experience of the Global Neurosurgery Course held in March 2023 in Dar es Salaam, Tanzania. We describe the funding, planning, organization, and teaching methods along with participant and faculty feedback. RESULTS: The course trained 121 participants with 63 faculty-42 from Tanzania and 21 international faculty. Training methods included lectures, hands-on surgical teaching, webinars, case discussions, surgical simulation, virtual reality, and bedside teaching. Although there were challenges with equipment and Internet connectivity, participant feedback was positive, with overall improvement in knowledge reported in all topics taught during the course. CONCLUSIONS: International collaboration can be successful in delivering topic-specific training that aims to address the everyday needs of surgeons in their local setting. Suggestions for future courses include increasing training on allied topics to neurosurgery and neurosurgical subspecialty topics, reflecting the growth in neurosurgical capacity and services offered in Tanzania.

Fulfilling the specialist neurosurgical workforce needs in Africa: a systematic review and projection toward 2030.

OBJECTIVE: Africa contributes significantly to the global neurosurgical disease burden but has only 1% of the neurosurgery workforce. This study appraises the neurosurgical workforce and training capacity in Africa and projects the workforce capacity by 2030. METHODS: The authors conducted a systematic review of the online literature on neurosurgical workforce and training in Africa obtained from three journal databases (PubMed, Embase, and African Index Medicus), as well as from a gray literature search, between September and December 2020. Included literature passed a two-level screening conducted using a systematic review software by a team of two independent reviewers. Data were extracted from selected articles and documented and analyzed on spreadsheets. RESULTS: One hundred and fifty-nine eligible articles were analyzed: 1974 neurosurgeons serve 1.3 billion people in Africa (density 0.15 per 100,000 persons, ratio 1:678,740), with uneven distribution between the regions. North Africa has 64.39% of the neurosurgical workforce (n = 1271), followed by Southern Africa (12.66%, n = 250), West Africa (11.60%, n = 229), East Africa (8.26%, n = 163), and Central Africa (3.09%, n = 61). At an exponential growth rate of 7.03% (95% CI 5.83%-8.23%) per annum, Africa will have 3418 (95% CI 1811-6080) neurosurgeons by 2030, with a deficit of 5191 neurosurgeons, based on population workforce targets. In terms of training, there are 106 neurosurgery training institutions in 26 African countries. North Africa has 52 training centers (49.05%), West Africa 23 (21.70%), East Africa 15 (14.15%), Southern Africa 14 (13.21%), and Central Africa 2 (1.89%). The major regional training programs are those of the West African College of Surgeons (24 sites in 7 countries) and the College of Surgeons of East, Central, and Southern Africa (17 sites in 8 countries). CONCLUSIONS: The study is limited as it is based on the online literature, some of which includes modeled estimates with questionable reliability. However, the results indicate that while countries in North Africa are expected to surpass their population workforce requirements, sub-Saharan African countries are likely to have significant workforce deficits accentuated by the paucity of neurosurgery training programs. To meet the 2030 population workforce requirements, the continent's exponential growth rate should be scaled up to 15.87% per annum. Scaling up neurosurgical training would help to meet this target and requires collaborative efforts from continental, regional, and national agencies and international organizations.

Assessment of the Neurosurgical Capacity in Ghana: Challenges and Opportunities.

BACKGROUND: Low- and middle-income countries experience numerous challenges in the provision of neurosurgical care. However, limited information exists on the neurosurgical workforce and the constraints under which care is delivered in Ghana, West Africa. METHODS: A 19-item survey assessing neurosurgical workforce, infrastructure, and education was administered to Ghanaian consultant neurosurgeons and neurosurgeon trainees between November 8, 2021, and January 20, 2022. The data were analyzed using summary descriptions, and qualitative data were categorized into themes. RESULTS: There were 25 consultant neurosurgeons and 8 neurosurgical trainees (from 2 training centers) identified at 11 hospitals in Ghana totaling a workforce density of 1 neurosurgeon per 1,240,000. Most neurosurgical centers were located in Accra, the capital city. Almost half of the population did not have access to a hospital with a neurosurgeon in their region. Of hospitals, 82% had in-house computed tomography and/or magnetic resonance imaging scanners. In the operating room, most neurosurgeons had access to a high-speed drill (91%) but lacked microscopes and endoscopic sets (only 64% and 36% had these tools, respectively). There were no neurointensivists or neurological intensive care units in the entire country, and there was a paucity of neurovascular surgeries and functional neurosurgical procedures. CONCLUSIONS: The provision of neurosurgical care in Ghana has come a long way since the 1960s. However, the neurosurgical community continues to face significant challenges. Alleviating these barriers to care will call for systems-level changes that allow for the prioritization of neurosurgical care within the Ghanaian health care system.

Overcoming Barriers in Neurosurgical Education: A Novel Approach to Practical Ventriculostomy Simulation.

BACKGROUND: In the high-risk, high-stakes specialty of neurosurgery, traditional teaching methods often fail to provide young residents with the proficiency needed to perform complex procedures in stressful situations, with direct effects on patient outcomes. Physical simulators provide the freedom of focused, hands-on training in a more controlled environment. However, the adoption of simulators in neurosurgical training remains a challenge because of high acquisition costs, complex production processes, and lack of realism. OBJECTIVE: To introduce an easily reproducible, cost-effective simulator for external ventricular drain placements through various ventriculostomy approaches with life-like tactile brain characteristics based on real patients' data. METHODS: Whole brain and skull reconstruction from patient's computed tomography and MRI data were achieved using freeware and a desktop 3-dimensional printer. Subsequently, a negative brain silicone mold was created. Based on neurosurgical expertise and rheological measurements of brain tissue, gelatin in various concentrations was tested to cast tactilely realistic brain simulants. A sample group of 16 neurosurgeons and medical students tested and evaluated the simulator in respect to realism, haptics, and general usage, scored on a 5-point Likert scale. RESULTS: We saw a rapid and significant improvement of accuracy among novice medical students. All participants deemed the simulator as highly realistic, effective, and superior to conventional training methods. CONCLUSION: We were able to demonstrate that building and implementing a high-fidelity simulator for one of the most important neurosurgical procedures as an effective educational and training tool is achievable in a timely manner and without extensive investments.
