Abstract
OBJECTIVE Addressing equitable opportunities for medical student (MS) education is important for minimizing disparities in neurosurgical care. However, international MSs, particularly from low- and middle-middle income countries (LMICs) may lack access to educational opportunities compared with their contemporaries in high-income countries. We compare the usefulness of virtual neurosurgery training camps (VNTC) between U.S. and international MSs. METHODS A survey assessing demographics, baseline interests, and ratings of usefulness was sent to attendees after the VNTC. Ratings were compared between international and U.S. MSs. RESULTS Thirty-three (27.7%) of 119 attendees were international MSs, of whom 24 (72.7%) were from LMICs. International MSs were more likely to hold an advanced degree (P = 0.0009), more likely to be MS3/MS4s (P = 0.0111) or postdoctoral (P < 0.0001), and less likely to be MS1/MS2s (P = 0.0059). After the VNTC, international MSs reported greater increase in interest in neurosurgery in general (P = 0.0009) and subspecialties of spine (P = 0.0002), peripheral nerve (P = 0.002), vascular (P = 0.0468), functional/epilepsy (P = 0.001), pediatric (P = 0.0285), and trauma/neurocritical care (P = 0.0067). International MSs reported greater post-VNTC willingness to pursue a career in neurosurgery (P = 0.0001), likelihood of taking a year off during medical school (P = 0.0363), and preparedness for subinternships (P = 0.0003). International MSs reported greater increases in awareness of burnout (P = 0.0157) and work-life balance in neurosurgery (P = 0.0249). CONCLUSIONS International MSs experience prolonged periods of education before applying to residency and have unmet informational needs. Distance learning is useful for international MSs. MS neurosurgery education, through online platforms, represents a long-term strategy for addressing disparities in neurosurgical care worldwide.

The Application of Guideline-Based Care for Traumatic Brain and Spinal Cord Injury in Low- and Middle-Income Countries: A Provider-Based Survey. World Neurosurg X 2022; 15:100121. [PMID: 35515346 PMCID: PMC9061784 DOI: 10.1016/j.wnsx.2022.100121] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/02/2022] [Accepted: 03/04/2022] [Indexed: 11/22/2022] Open
Abstract
Objective Neurosurgical guidelines have resulted in improved clinical outcomes and more optimized care for many complex neurosurgical pathologies. As momentum in global neurosurgical efforts has grown, there is little understanding about the application of these guidelines in low- and middle-income countries. Methods A 29-question survey was developed to assess the application of specific recommendations from neurosurgical brain and spinal cord injury guidelines. Surveys were distributed to an international cohort of neurosurgeons and neurotrauma stakeholders. Results A total of 82 of 222 (36.9%) neurotrauma providers responded to the survey. The majority of respondents practiced in low- and middle-income countries settings (49/82, 59.8%). There was a significantly greater mean traumatic brain injury volume in low-income countries (56% ± 13.5) and middle-income countries (46.5% ± 21.3) compared with high-income countries (27.9% ± 13.2), P < 0.001. Decompressive hemicraniectomy was estimated to occur in 61.5% (±30.8) of cases of medically refractory intracranial pressure with the lowest occurrence in the African region (44% ± 37.5). The use of prehospital cervical immobilization varied significantly by income status, with 36% (±35.6) of cases in low-income countries, 52.4% (±35.5) of cases in middle-income countries, and 95.2% (±10) in high-income countries, P < 0.001. Mean arterial pressure elevation greater than 85 mm Hg to improve spinal cord perfusion was estimated to occur in 71.7% of cases overall with lowest occurrence in Eastern Mediterranean region (55.6% ± 24). Conclusions While some disparities in guideline implementation are inevitably related to the availability of clinical resources, other differences could be more quickly improved with accessibility of current evidence-based guidelines and development of local data.

The unmet global burden of cranial epidural hematomas: A systematic review and meta-analysis. Clin Neurol Neurosurg 2022; 219:107313. [PMID: 35688003 DOI: 10.1016/j.clineuro.2022.107313] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/27/2022] [Revised: 05/25/2022] [Accepted: 05/27/2022] [Indexed: 11/24/2022]
Abstract
OBJECTIVE Approximately 69 million people suffer from traumatic brain injury (TBI) annually. Patients with isolated epidural hematomas (EDH) with access to timely surgical intervention often sustain favorable outcomes. Efforts to ensure safe, timely, and affordable access to EDH treatment may offer tremendous benefits. METHODS A comprehensive literature search was conducted. A random-effects model was used to pool the outcomes. Studies were further categorized into groups by World Bank Income classification: high-income countries (HICs) and low- and middle-income countries (LMICs). RESULTS Forty-nine studies were included, including 36 from HICs, 12 from LMICs, and 1 from HIC / LMIC. Incidence of EDH amongst TBI patients 8.2 % (95 % CI: 5.9,11.2), including 9.2 % (95 %CI 6.4,13.2) in HICs and 5.8 % (95 % CI: 3.1,10.7) in LMICs (p = 0.20). The overall percent male was 73.7 % and 47.4 % were caused by road traffic accidents. Operative rate was 76.0 % (95 %CI: 67.9,82.6), with a numerically lower rate of 74.2 % (95 %CI: 64.0,81.8) in HICs than in LMICs 82.9 % (95 %CI: 65.4,92.5) (p = 0.33). This decreased to 55.5 % after adjustment for small study effect. The non-operative mortality (5.3 %, 95 %CI: 2.2,12.3) was lower than the operative mortality (8.3 %, 95 %CI: 4.6,14.6), with slightly higher rates in HICs than LMICs. This relationship remained after adjustment for small study effect, with 9.3 % operative mortality compared to 6.9 % non-operative mortality. CONCLUSION With an overall EDH incidence of 8.2 % and an operative rate of 55.5 %, 3.1 million people worldwide require surgery for traumatic EDH every year, most of whom are in prime working age. Given the favorable prognosis with treatment, traumatic EDH is a strong investment for neurosurgical capacity building.

World Neurosurg 2022; 164:413-423.e3. [PMID: 35636659 DOI: 10.1016/j.wneu.2022.05.093] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Revised: 05/19/2022] [Accepted: 05/20/2022] [Indexed: 11/18/2022]
Abstract
OBJECTIVE Craniosynostosis leads to craniofacial deformity and may result in raised intracranial pressure, neurocognitive deficits, and psychosocial issues if left untreated. The global epidemiology of craniosynostosis is unknown. We conducted a meta-analysis to estimate global birth prevalence. METHODS PubMed, Embase, and Scopus were searched. Articles were screened by title and abstract and then full text. Meta-analysis of birth prevalence was conducted. Birth prevalence figures were combined with metrics detailing the number of births in 2019 to estimate the number of children worldwide born with craniosynostosis annually. RESULTS Of 1378 resultant articles, 24 studies were included, including 20 providing data for craniosynostosis overall and 9 for nonsyndromic craniosynostosis. World Health Organization regions of included studies were 9 (37.5%) European Region, 8 (33.3%) Region of the Americas, 4 (16.7%) Western Pacific region, 2 (8.3%) African Region, and 1 (4.2%) Eastern Mediterranean Region. Lower middle-income countries represented only 4% of study manuscripts. The overall birth prevalence of craniosynostosis was 5.9 per 10,000 live births (20 studies; 95% confidence interval [CI]: 3.9, 8.4; I2 = 100%). The birth prevalence of nonsyndromic craniosynostosis was 5.2 per 10,000 live births (9 studies; 95% CI: 3.4, 7.3; I2 = 98%). The number of children born globally with craniosynostosis in 2019 was estimated to be 84,665 (95% CI: 55,965, 120,540), including 72,857 (95% CI: 47,637, 120,280) with nonsyndromic craniosynostosis. CONCLUSIONS Craniosynostosis is a common condition that affects the neurocognitive and craniofacial skeletal development of children worldwide. Initiatives to scale up capacity for craniosynostosis epidemiologic research and clinical care are warranted, particularly in low- and middle-income countries.

[PMID: 35609725 DOI: 10.1016/j.wneu.2022.05.053] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2022] [Revised: 05/12/2022] [Accepted: 05/13/2022] [Indexed: 11/29/2022]
Abstract
BACKGROUND Neurosurgery-specific research plays a critical role in improving outcomes in patients with neurosurgical diseases. Despite the high burden of neurosurgical diseases in Ethiopia, little is known about types of neurosurgical research from Ethiopia. The goal of this scoping review is to assess the quantity and types of neurosurgical research published in peer-reviewed journals by authors from Ethiopia. METHODS PubMed, CINAHL, Embase, and Scopus were searched for Ethiopian neurosurgery literature published from 2001 to 2021. We selected articles based on the following criteria: articles must 1) discuss topics within neurosurgery and 2) focus on clinical practice and/or public health in Ethiopia. We collected data on research originality, study designs, and clinical versus public health research. The frequencies and percentages of categorical variables were reported. All analyses were conducted using Jamovi software. RESULTS Of the 362 results, 89 neurosurgical research articles were included in the final analysis. Of the 89 articles, case reports/series were most common (28.7%), followed by retrospective cohort (20.7%) and prospective cohort studies (18.4%). There were 8 literature reviews (9.2%) and 1 systematic review and meta-analysis (1.1%). No randomized controlled trial was found. Of all articles, 66 (75.9%) focused on clinical practice, and 21 (23.6%) were related to the public health aspect of neurosurgery. Forty-two articles (48.3%) included authors only from Ethiopia; 37 articles (42.5%) involved collaboration between Ethiopian and authors from another country, and 8 articles (9.2%) did not have Ethiopian authors. CONCLUSIONS Neurosurgery research from Ethiopia is lacking, despite its high disease burden. Case reports/series and cohort studies remain the mainstay, with few systematic reviews and no randomized controlled trial. International collaboration accounts for approximately half of Ethiopian neurosurgery research output. Further research support and infrastructure should be developed to encourage neurosurgery articles from Ethiopia.

Abstract
The global deficiency in surgical care has been highlighted in the past several years, through the publication of the Lancet Commission on Global Surgery in 2015, the passage of WHA Resolution 68.15, and concerted efforts by advocacy organizations such as the G4 Alliance.Approximately 23,300 additional neurosurgeons are estimated to be needed to address the greater than 5 million essential neurosurgical cases that are not performed annually, most in low- and middle-income countries (LMICs). However, increasing recognition of the ease and feasibility of virtual technology prompted a shift towards virtual modes of communication. InterSurgeon (https://www.intersurgeon.org/), an independent, internet-based social network platform, has allowed for formal connection between global surgery advocates who may have complementary needs and resources.This manuscript aims to: 1) characterize the current progress of InterSurgeon, 2) describe lessons learned from the creation and use of InterSurgeon, and 3) discuss future directions for InterSurgeon. Equitable, well-designed collaborations are central to progress in global neurosurgery. InterSurgeon has catalyzed collaborations within global neurosurgery across world regions and country income status. In addition to its role in facilitating traditional in person collaborations, InterSurgeon will become an increasingly important tool for connecting surgeons worldwide as virtual collaboration and augmented reality training paradigms become important components of global surgery capacity building.

Abstract
BACKGROUND Traumatic brain injury (TBI) disproportionately affects children within low- and middle-income countries (LMICs). Prehospital emergency care can mitigate secondary brain injury and improve outcomes. Here, we systematically review clinical practice guidelines (CPGs) for pediatric TBI with the goal to inform LMICs prehospital care. METHODS A systematic search was conducted in PubMed/Medline, Embase, and Web of Science databases. We appraised evidence-based CPGs addressing prehospital management of pediatric TBI using the Appraisal of Guidelines for Research & Evaluation (AGREE) tool. CPGs were rated as high-quality if ≥ 5 (out of 6) AGREE domains scored > 60%. RESULTS Of the 326 articles identified, 10 CPGs were included in analysis. All 10 were developed in HICs, and 4 were rated as high-quality. A total of 154 pediatric prehospital recommendations were grouped into three subcategories, initial assessment (35.7%), prehospital treatment (38.3%), and triage (26.0%). Of these, 79 (51.3%) were evidence-based with grading, and 31 (20.1%) were consensus-based without direct evidence. CONCLUSION Currently available CPGs for prehospital pediatric TBI management were all developed in HICs. Four CPGs have high-quality, and recommendations from these can serve as frameworks for LMICs or resource-limited settings. Context-specific evaluation and implementation of evidence-based recommendations allow LMIC settings to respond to the public health crisis of pediatric TBI and address gaps in trauma care systems.

[PMID: 34687934 DOI: 10.1016/j.wneu.2021.10.112] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/01/2021] [Revised: 10/13/2021] [Accepted: 10/13/2021] [Indexed: 10/20/2022]
Abstract
BACKGROUND The provision of equitable and affordable health care has become increasingly challenging as advanced technology is introduced, particularly in developing countries. We explored the hypothesis that focused, small-scale mini-public-private partnerships have a potential role in providing equitable and affordable access to advanced technology for the benefit of all patients in developing nations, particularly middle-income countries. METHODS A clinician-led financial plan was developed at the University of Malaya to create the Centre for Image Guidance and Minimally Invasive Therapy (CIGMIT) to provide an integrated platform for high-end care for Malaysian patients of all ages, both public and private, requiring complex neurosurgical and spinal procedures and stereotactic and intensity-modulated radiotherapy. The challenges faced during development of the plan were documented together with an audit of patient throughput and analyses of financial risk and return. RESULTS CIGMIT opened in 2015. Patient throughput, both public and private, progressively increased in all facilities. In 2015-2019, 37,724 patients used the Centre's facilities. CIGMIT has become progressively more profitable for the University of Malaya, the public and private hospitals, and the investor. CIGMIT has weathered the challenges posed by coronavirus disease 19. CONCLUSIONS Focused, small-scale mini-public-private partnerships have a potential role in providing advanced technology for the benefit of patients in developing nations, particularly middle-income countries, subject to an approach that balances equity of access between public and private health care systems with fair reward.

Abstract
BACKGROUND Neurotrauma is a leading cause of morbidity and mortality around the world. Assessment of injury prevention and prehospital care for neurotrauma patients is necessary to improve care systems. METHODS A 29-question electronic survey was developed based on the Enhancing the Quality and Transparency Of health Research (EQUATOR) checklist to assess neurotrauma policies and laws related to safety precautions. The survey was distributed to members of World Health Organization regions that were considered to be experienced medical authorities in neurosurgery and traumatic brain injury. RESULTS There were 82 (39%) responses representing 46 countries. Almost all respondents (95.2%) were within the neurosurgical field. Of respondents, 40.2% were from high-income countries (HICs), and 59.8% were from low- and middle-income countries (LMICs). Motor vehicle accidents were reported as the leading cause of neurotrauma, followed by workplace injury and assault. Of respondents, 84.1% reported having a helmet law in their country. HICs (4.38 ± 0.78) were ranked more likely than LMICs (2.88 ± 1.34; P = 0.0001) to enforce helmet laws on a scale of 1-10. Effectiveness of helmet laws was rated as 3.94 ± 0.95 out of 10. Measures regarding prehospital care varied between HICs and LMICs. Patients in HICs were more likely to use public emergency ambulance transportation (81.8% vs. 42.9%; P = 0.0004). All prehospital personnel having emergency training was also reported to be more likely in HICs than LMICs (60.6% vs. 8.7%; P = 0.0001). CONCLUSIONS When injuries occur, timely access to neurosurgical care is critical. A focus on prehospital components of the trauma system is paramount, and policymakers can use the information presented here to implement and refine health care systems to ensure safe, timely, affordable, and equitable access to neurotrauma care.

Abstract
BACKGROUND Despite the growing incidence of traumatic brain injury (TBI) in Sub-Saharan Africa, there is yet to be a study to map the current burden of the disease on the continent. This scoping review aims to outline the literature on TBI. METHODS This scoping review was conducted in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analysis extension for scoping reviews. A search string was developed to identify studies relating to TBI epidemiology, management, and outcomes. The search was applied to Medline, Embase, and Global Medicus Index. RESULTS In total, 107 studies were included in the final analysis. More than one half originated from South Africa. Seventy-five studies were published in 2013 or later. Studies recruited a median of 115 patients: 83.5 male and 31 female. TBI affected all age groups (range = 0-105 years) and sexes but was more common among young males aged 20-40. Road traffic accidents caused TBI in a median of 71 patients. Other major causes included assault (median = 39.5) and falls (median = 12.5). Craniectomies were the most commonly reported surgical treatment (18.7%) followed by burr holes (7.5%). Four studies (3.7%) reported delays in seeking neurotrauma care, with delays in reaching a neurotrauma facility and delays in receiving care being reported in 15 studies (14%) each. Glasgow Outcome Scale score was reported in 28 (26.1%) studies, whereas quality of life measures were reported in 2 (1%). Younger age was associated with favorable outcomes. CONCLUSIONS There is an increased need for TBI research, education, and training in Sub-Saharan Africa. This will aid stakeholders in optimizing patient management and outcome.

BACKGROUND Global neurosurgery operates at the intersection of neurosurgery and public health. Although most global neurosurgery initiatives have targeted neurosurgeons and trainees, medical students represent the future of global neurosurgery. METHODS A narrative review of the literature regarding research methodology, education, economics, health policy, health advocacy, relevant to global neurosurgery was conducted. RESULTS We summarize pearls that all medical students interested in global neurosurgery should know. DISCUSSION To become effective agents of change within global neurosurgery, medical students must master competencies of motivation, organization, collaborativeness, dependability, flexibility, resilience, creative problem-solving, ethical thinking, cultural humility, and global awareness and gain knowledge and skills regarding research, education, policy making, and advocacy. Discussions with neurosurgeons and trainees, neurosurgery interest groups, conferences, university global neurosurgery initiatives, and student organizations represent opportunities for learning and becoming involved in global neurosurgery.

Abstract
Five million neurosurgical cases go untreated each year. This is in part due to the lack of neurosurgical care providers. The World Federation of Neurosurgical Societies has spearheaded efforts to monitor the number of neurosurgical providers around the globe since 2016. In this perspective, we discuss why, when, and how the neurosurgical workforce should be measured.

Abstract
Background: Barriers to care cause delays in seeking, reaching, and getting care. These delays affect low-and middle-income countries (LMICs), where 9 out of 10 LMIC inhabitants have no access to basic surgical care. Knowledge of healthcare utilization behavior within underserved communities is useful when developing and implementing health policies. Little is known about the neurosurgical health-seeking behavior of African adults. This study evaluates public awareness, knowledge of availability, and readiness for neurosurgical care services amongst African adults. Methodology: The cross-sectional study will be run using a self-administered e-survey hosted on Google Forms (Google, CA, USA) disseminated from 10th May 2021 to 10th June 2021. The Questionnaire would be in two languages, English and French. The survey will contain closed-ended, open-ended, and Likert Scale questions.

Rosseau G, Kim EE, Barthélemy EJ, Yusuf M, Dahir SM, Tolessa CS, Yusuuf MA, Carter A, Vryhof D, Geelhoed GW, Shlobin NA. The Current State of Neurosurgery in Somaliland. World Neurosurg 2021; 153:44-51. [PMID: 34229101 DOI: 10.1016/j.wneu.2021.06.136] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/08/2021] [Revised: 06/26/2021] [Accepted: 06/28/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Surgical conditions account for as much as one third of the global burden of disease, yet 5 billion people worldwide do not have access to timely, affordable surgical care. These disparities in access to timely surgical care are most pronounced in low- and middle-income countries, where the availability of specialty surgical services such as neurosurgery are severely limited or completely absent. The African autonomous region of Somaliland, in the Horn of Africa, is one such region. METHODS Discussions were conducted with key individuals in Somaliland to ascertain the current state of neurosurgery in Somaliland. RESULTS The current state of neurosurgery in Somaliland was characterized. First, a background on the recent history of the republic and the surrounding region was furnished, which provides context for the challenging socioeconomic conditions in Somaliland. Brief biographical sketches were presented of local leaders and general surgeons who are actively working to improve economic and health conditions and who welcome opportunities to improve all health services, including neurosurgery. In addition, an overview was presented of new initiatives in capacity building in neurosurgery and sources of directed training and care in neurosurgery. CONCLUSIONS This article provides the first-ever assessment of current neurosurgery-related activity in Somaliland. The article provides recommendations to guide the international neurosurgery community in future contributions.

[PMID: 34052452 DOI: 10.1016/j.wneu.2021.05.071] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/30/2021] [Revised: 05/16/2021] [Accepted: 05/17/2021] [Indexed: 10/21/2022]
Abstract
BACKGROUND Inequitable access to surgical care is most conspicuous in low-income countries (LICs), such as Ethiopia, where infectious diseases, malnutrition, and other maladies consume the lion's share of the available health resources. The aim of this article was to provide an update on the current state of neurosurgery in Ethiopia and identify targets for future development of surgical capacity as a universal health coverage component in this East African nation. METHODS Publicly available data included in this report were gathered from resources published by international organizations. A PubMed search was used for a preliminary bibliometric analysis of scholarly output of neurosurgeons in Ethiopia and other low-income countries. Statistical analysis was used to determine the correlation between the number of neurosurgeons and academic productivity. RESULTS Neurosurgeon density has increased >20-fold from 0.0022 to 0.045 neurosurgeons per 100,000 population between 2006 and 2020. The increase in neurosurgeons was strongly correlated with an increase in total publications (P < 0.001) and the number of new publications per year (P = 0.003). Despite recent progress, the availability of neuroimaging equipment remains inadequate, with 38 computed tomography scanners and 11 magnetic resonance imaging machines for a population of 112.07 million. The geographic distribution of neurosurgical facilities is limited to 12 urban centers. CONCLUSIONS Ethiopian neurosurgery exemplifies the profound effect of international partnerships for training local surgeons on progress in low-income countries toward improved neurosurgical capacity. Collaborations that focus on increasing the neurosurgical workforce should synchronize with efforts to enhance the availability of diagnostic and surgical equipment necessary for basic neurosurgical care.

[PMID: 33905905 DOI: 10.1016/j.wneu.2021.04.077] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/25/2021] [Revised: 04/16/2021] [Accepted: 04/17/2021] [Indexed: 11/28/2022]
Abstract
BACKGROUND Access to timely neurosurgical care in particular remains limited worldwide, and is associated with increased morbidity and mortality, a decrease in overall life expectancy, and catastrophic economic costs. To date, access to neurosurgical care has not been completely studied and reported in the Caribbean neurosurgical literature. In this study, we aim to understand the geographic distribution of hospital facilities with neurosurgical capacity among the CARICOM member states to determine timely access to neurosurgical care. METHODS We assessed geographical access to facilities capable of providing neurosurgical care in the Caribbean. The GPS coordinates of the hospitals that provide neurosurgical care were identified using street addresses and satellite imaging from Google Maps. Facilities with neurosurgical care were mapped in ArcGIS Pro (Version 2.6.0). using Manhattan distance. We identified the area around each facility and stratified by 30- minute, 1-hour, 2-hour, and 4-hour geographic driving intervals. RESULTS A total of 16 hospitals were identified as providing neurosurgical care in the Caribbean. Our results suggest that 14 million people (76% of the population) had 4-hour geographic access to a facility capable of providing neurosurgical care. In addition, 7 million people (40% of the population) had 2-hour geographical access to neurosurgical care. CONCLUSIONS Timely access to care is an important tenet of global neurosurgery. We found that 3.5 million Caribbean residents are outside of the access zone to neurosurgical capacity. Public health advocates, governments, providers, and patients should be aware of the inequity in access to neurosurgical care and should collectively work to close the gap.

World Neurosurg 2021; 149:174-180. [PMID: 33647494 DOI: 10.1016/j.wneu.2021.02.104] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.7] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2020] [Revised: 02/20/2021] [Accepted: 02/21/2021] [Indexed: 11/16/2022]
Abstract
BACKGROUND Evolutions in cranioplasty have allowed for the creation of customized implants via advances in 3-dimensional (3D) printing technology, although the high cost associated with this technique presents a barrier for low-income countries. Through an international collaboration, our team in Da Nang, Vietnam is able to create low-cost, customized titanium implants for patients with skull defects. We discuss the details of our collaboration and present our experience with this procedure. METHODS We conducted a retrospective review of 35 patients who underwent cranioplasty using custom-made titanium implants. The molding and implant making processes were performed by our neurosurgeons using a 3D printer donated by the United Kingdom-based nongovernmental organization Facing the World. We obtained demographic and preoperative data (reason for skull defect, location, surface area measurement of defect) and postoperative data (complications, cosmetic outcome, and patient satisfaction). RESULTS The median patient age was 27 years (range, 16-60 years). Primary indications for craniectomy included traumatic brain injury from motor vehicle accident (77.1%), cerebrovascular disease (11.4%), implant failure following previous cranioplasty (5.7%), and fall (5.7%). Postoperatively, all implants were found to have an excellent fit; at 6-month follow-up, none of the implants required removal. Complications included 4 postoperative hematomas and 1 surgical site infection. All the patients had improved aesthetic appearance and high satisfaction. CONCLUSIONS Cranioplasty using customized titanium implants yields excellent results for patients with skull defects, demonstrating the practicality of this technique for cranioplasty in low-income countries. Our experience highlights the importance of ongoing international collaboration to improve neurosurgical care in these countries.

Abstract
Telecollaboration via web-based platforms has emerged as a tool to relieve constraints on the establishment of tumor boards for neurosurgical oncology. Challenging tumor cases arising in low- and middle-income countries may benefit from the use of such models. The case of a 5-year-old boy presenting in Western Kenya with a challenging tumor and symptomatic hydrocephalus was presented on a novel web platform to a multi-national audience of neurosurgeons. The treating neurosurgeon invited a physician network to review the case vignette and radiographic images. Respondents independently offered input during a prescribed response period. Three respondents provided surgical opinions during a 24-h response period. The treating neurosurgeon utilized the pooled input to determine a course of action for the patient. When a web-based platform is available, lone neurosurgeons in low-resource settings may nevertheless apply multi-national, multi-institutional perspectives to challenging oncology cases.

Abstract
INTRODUCTION Training capable and competent neurosurgeons to work in underserved regions of the world is an essential component of building global neurosurgical capacity. One strategy for achieving this goal is establishing longitudinal partnerships between institutions in low- and middle-income countries (LMICs) and their counterparts in high-income countries (HICs) utilizing a multi-component model. We describe the initial experience of the Children's of Alabama (COA) Global Surgery Program partnership with multiple Vietnamese neurosurgical centers. METHODS The training model developed by the COA Global Surgery Program utilizes three complementary and interdependent methods to expand neurosurgical capacity: in-country training, out-of-country training, and ongoing support and mentorship. Multiple Vietnamese hospital systems have participated in the partnership, including three hospitals in Hanoi and one hospital in Ho Chi Minh City. RESULTS During the 7 years of the partnership, the COA and Viet Nam teams have collaborated on expanding pediatric neurosurgical care in numerous areas of clinical need including five subspecialized areas of pediatric neurosurgery: cerebrovascular, epilepsy, neuroendoscopy for hydrocephalus management, craniofacial, and neuro-oncology. CONCLUSION Long-term partnerships between academic departments in LMICs and HICs focused on education and training are playing an increasingly important role in scaling up global surgical capacity. We believe that our multi-faceted approach consisting of in-country targeted hands-on training, out-of-country fellowship training at the mentor institution, and ongoing mentorship using telecollaboration and Internet-based tools is a viable and generalizable model for enhancing surgical capacity globally.

Abstract
BACKGROUND The setting of a randomized trial can determine whether its findings are generalizable and can therefore apply to different settings. The contribution of low- and middle-income countries (LMICs) to neurosurgical randomized trials has not been systematically described before. OBJECTIVE To perform a systematic analysis of design characteristics and methodology, funding source, and interventions studied between trials led by and/or conducted in high-income countries (HICs) vs LMICs. METHODS From January 2003 to July 2016, English-language trials with >5 patients assessing any one neurosurgical procedure against another procedure, nonsurgical treatment, or no treatment were retrieved from MEDLINE, Scopus, and Cochrane Library. Income classification for each country was assessed using the World Bank Atlas method. RESULTS A total of 73.3% of the 397 studies that met inclusion criteria were led by HICs, whereas 26.7% were led by LMICs. Of the 106 LMIC-led studies, 71 were led by China. If China is excluded, only 8.8% were led by LMICs. HIC-led trials enrolled a median of 92 patients vs a median of 65 patients in LMIC-led trials. HIC-led trials enrolled from 7.6 sites vs 1.8 sites in LMIC-led studies. Over half of LMIC-led trials were institutionally funded (54.7%). The majority of both HIC- and LMIC-led trials evaluated spinal neurosurgery, 68% and 71.7%, respectively. CONCLUSION We have established that there is a substantial disparity between HICs and LMICs in the number of published neurosurgical trials. A concerted effort to invest in research capacity building in LMICs is an essential step towards ensuring context- and resource-specific high-quality evidence is generated.

Abstract
Background: Intracranial convexity lesions are poorly defined by recognizable anatomical landmarks. Even in expert hands, exact localization of small subcortical lesion and its projection to the skull is sometimes unreliable and can cause potential surgical complications. In this report, a simple and handy technique for localizing superficial intracranial lesions on the scalp under computed tomography (CT)-scan guidance is described. Methods: This technique, HeaDax, is based on using extracranial landmarks. We constructed an isosceles square triangle with three pieces of copper electrical wire and placed it on the skin scalp. Then, we took a CT-scan but without the need of the classic head reference planes (e.g., orbitomeatal or along the orbital roof). Results: For the measurements, we need to have the intracranial lesion located on the CT slice with respect to the two landmarks which are the height and hypotenuse of the triangle. The promising preliminary results of HeaDax applied to a phantom skull model encourage us to use it successfully for our first patient presenting a right subcortial supramarginal retrorolandic cavernoma. Conclusion: HeaDax procedure is a good alternative for localizing superficial intracranial lesions on the skin scalp under CT-scan or magnetic resonance imaging guidance. It can be used as a substitute when stereotactic and neuronavigation systems are not easily available, especially in developing countries and in resource-limited environments. HeaDax has a true potential for further developments and applications in cranial surgery.

Abstract
OBJECTIVE Neurosurgery departments worldwide have been forced to restructure their training programs because of the coronavirus disease 2019 (COVID-19) pandemic. In this study, we describe the impact of COVID-19 on neurosurgical training in Southeast Asia. METHODS We conducted an online survey among neurosurgery residents in Indonesia, Malaysia, Philippines, Singapore, and Thailand from May 22 to 31, 2020 using Google Forms. The 33-item questionnaire collected data on elective and emergency neurosurgical operations, ongoing learning activities, and health worker safety. RESULTS A total of 298 of 470 neurosurgery residents completed the survey, equivalent to a 63% response rate. The decrease in elective neurosurgical operations in Indonesia and in the Philippines (median, 100% for both) was significantly greater compared with other countries (P < 0.001). For emergency operations, trainees in Indonesia and Malaysia had a significantly greater reduction in their caseload (median, 80% and 70%, respectively) compared with trainees in Singapore and Thailand (median, 20% and 50%, respectively; P < 0.001). Neurosurgery residents were most concerned about the decrease in their hands-on surgical experience, uncertainty in their career advancement, and occupational safety in the workplace. Most of the residents (n = 221, 74%) believed that the COVID-19 crisis will have a negative impact on their neurosurgical training overall. CONCLUSIONS An effective national strategy to control COVID-19 is crucial to sustain neurosurgical training and to provide essential neurosurgical services. Training programs in Southeast Asia should consider developing online learning modules and setting up simulation laboratories to allow trainees to systematically acquire knowledge and develop practical skills during these challenging times.

Abstract
OBJECTIVE Global neurosurgery is the practice of neurosurgery with the primary purpose of delivering timely, safe, and affordable neurosurgical care to all who need it. The aim of this study is to identify the most frequently cited articles in global neurosurgery through a bibliographic review to characterize articles and trends around this growing topic. METHODS The top most-cited articles in global neurosurgery were determined by searching the Web of Science database using a priori search terms. Articles with at least 5 citations were selected, and there were no time period or language restrictions. The data were extracted from each included article and all characteristics were summarized. RESULTS A total of 932 articles were identified using the search terms; 69 articles fulfilled inclusion criteria and 17 articles were selected that had more than 5 citations. The articles' number of citations ranged from 6 to 98 for the most-cited article. Authors from, or affiliated with, 14 countries contributed to the 17 articles, and the country that had the greatest representation was the United States. The main topic discussed was surgical capacity, the second topic was the treatment of different neurosurgical conditions, and volunteerism was the third topic. CONCLUSIONS There is currently a deficit in both the amount of literature surrounding the topic of global neurosurgery and how much that literature is cited. Developing innovative ways to increase academic productivity within, or in collaboration with, low-middle income countries is essential to contribute to global neurosurgery.
