The ties that bind: innovation configurations in low- and middle-income healthcare delivery settings.

PURPOSE: This study examines innovation configurations (i.e. sets of product/service, social and business model innovations) and configuration linkages (i.e. factors that help to combine innovations) across six organizations as contingent upon organizational structure. DESIGN/METHODOLOGY/APPROACH: Using semi-structured interviews and available public information, qualitative data were collected and examined using content analysis to characterize innovation configurations and linkages in three local/private organizations and three foreign-led/public-private partnerships in Repiblik Ayiti (Haiti). FINDINGS: Organizations tend to combine product/service, social, and business model innovations simultaneously in locally founded private organizations and sequentially in foreign-based public-private partnerships. Linkages for simultaneous combination include limited external support, determined autonomy and shifting from a "beneficiary mindset," and financial need identification. Sequential combination linkages include social need identification, community connections and flexibility. RESEARCH LIMITATIONS/IMPLICATIONS: The generalizability of our findings for this qualitative study is subject to additional quantitative studies to empirically test the suggested factors and to examine other health care organizations and countries. PRACTICAL IMPLICATIONS: Locally led private organizations in low- and middle-income settings may benefit from considering how their innovations are in service to one another as they may have limited resources. Foreign based public-private partnerships may benefit from pacing their efforts alongside a broader set of stakeholders and ecosystem partners. ORIGINALITY/VALUE: This study is the first, to our knowledge, to examine how organizations combine sets of innovations, i.e. innovation configurations, in a healthcare setting and the first of any setting to examine innovation configuration linkages.

A guide to interpreting systematic reviews and meta-analyses in neurosurgery and surgery.

INTRODUCTION: Systematic reviews (SRs) and meta-analyses (MAs) are methods of data analysis used to synthesize information presented in multiple publications on the same topic. A thorough understanding of the steps involved in conducting this type of research and approaches to data analysis is critical for appropriate understanding, interpretation, and application of the findings of these reviews. METHODS: We reviewed reference texts in clinical neuroepidemiology, neurostatistics and research methods and other previously related articles on meta-analyses (MAs) in surgery. Based on existing theories and models and our cumulative years of expertise in conducting MAs, we have synthesized and presented a detailed pragmatic approach to interpreting MAs in Neurosurgery. RESULTS: Herein we have briefly defined SRs sand MAs and related terminologies, succinctly outlined the essential steps to conduct and critically appraise SRs and MAs. A practical approach to interpreting MAs for neurosurgeons is described in details. Based on summary outcome measures, we have used hypothetical examples to illustrate the Interpretation of the three commonest types of MAs in neurosurgery: MAs of Binary Outcome Measures (Pairwise MAs), MAs of proportions and MAs of Continuous Variables. Furthermore, we have elucidated on the concepts of heterogeneity, modeling, certainty, and bias essential for the robust and transparent interpretation of MAs. The basics for the Interpretation of Forest plots, the preferred graphical display of data in MAs are summarized. Additionally, a condensation of the assessment of the overall quality of methodology and reporting of MA and the applicability of evidence to patient care is presented. CONCLUSION: There is a paucity of pragmatic guides to appraise MAs for surgeons who are non-statisticians. This article serves as a detailed guide for the interpretation of systematic reviews and meta-analyses with examples of applications for clinical neurosurgeons.

CGRP as a potential mediator for the sexually dimorphic responses to traumatic brain injury.

BACKGROUND: The outcomes of traumatic brain injury (TBI) exhibit variance contingent upon biological sex. Although female sex hormones exert neuroprotective effects, the administration of estrogen and progesterone has not yielded conclusive results. Hence, it is conceivable that additional mediators, distinct from female sex hormones, merit consideration due to their potential differential impact on TBI outcomes. Calcitonin gene-related peptide (CGRP) exhibits sexually dimorphic expression and demonstrates neuroprotective effects in acute brain injuries. In this study, we aimed to examine sex-based variations in TBI structural and functional outcomes with respect to CGRP expression. METHODS: Male and female Sprague Dawley rats were exposed to controlled cortical impact to induce severe TBI, followed by interventions with and without CGRP inhibition. In the acute phase of TBI, the study centered on elucidating the influence of CGRP on oxidative stress, nuclear factor erythroid 2-related factor 2 (Nrf2) and endothelial nitric oxide synthase (eNOS) signaling in the peri-impact tissue. Subsequently, during the chronic phase of TBI, the investigation expanded to evaluate CGRP expression in relation to lesion volume, microvascular dysfunction, and white matter injury, as well as working and spatial memory, anxiety-like, and depression-like behaviors in subjects of both sexes. RESULTS: Female rats exhibited elevated levels of CGRP in the peri-impact brain tissue during both baseline conditions and in the acute and chronic phases of TBI, in comparison to age-matched male counterparts. Enhanced CGRP levels in specific brain sub-regions among female rats correlated with superior structural and functional outcomes following TBI compared to their male counterparts. CGRP inhibition induced heightened oxidative stress and a reduction in the expression of Nrf2 and eNOS in both male and female rats, with the observed alteration being more pronounced in females than in males. CONCLUSIONS: This study marks the inaugural identification of CGRP as a downstream mediator contributing to the sexually dimorphic response observed in TBI outcomes.

Investigating sex disparities in traumatic brain injury (TBI) is crucial for the advancement of precision therapeutics. Despite the neuroprotective effects demonstrated by female sex hormones, the administration of estrogen and progesterone has not produced conclusive results. Therefore, it is conceivable that additional mediators, separate from female sex hormones, warrant consideration due to their potential differential influence on TBI outcomes. In this study, we examined sex-related variations in calcitonin gene-related peptide (CGRP) expression in peri-impact brain tissue and investigated its potential implications on associated TBI outcomes. CGRP exhibits sexually dimorphic expression and exerts a multifaceted influence on diverse physiological processes that contribute to the pathophysiology of TBI. Our findings reveal that female rats exhibit heightened CGRP levels at both baseline and post-TBI within specific brain sub-regions, thereby contributing to superior structural and functional outcomes compared to their age-matched male counterparts. Additionally, we identified substantial sex-based variations in mechanisms modulated by CGRP pertaining to oxidative stress and microvascular dysfunction. The disparities in CGRP levels may be crucial for comprehending the advantageous outcomes noted in female TBI. Therefore, elucidating the sex-related distinctions in CGRP within TBI brains could pave the way for improved management and treatment strategies for TBI in both male and female individuals.

"Aneurysmal Subarachnoid Hemorrhage and Cocaine Consumption: A Systematic Review and Metanalysis".

BACKGROUND: The use of cocaine can lead to a variety of neurologic complications, including cerebral vasoconstriction, ischemia, aneurysm formation, and aneurysm rupture. A previous study has shown that cocaine use is associated with an increased risk of subarachnoid hemorrhage (SAH). This study conducted a systematic review and meta-analysis of observational studies to assess the association between cocaine use and the risk of poor neurological outcomes and mortality in patients with SAH. METHODS: A systematic review and meta-analysis were performed following the meta-analysis of observational studies in epidemiology (MOOSE) declaration for systematic reviews and the Cochrane Manual of Systematic Reviews and Meta-Analyses guidelines. Randomized controlled trials (RCTs), nonrandomized clinical trials, and prospective and retrospective cohort studies that reported data about adults who suffered Aneurysmal Subarachnoid Hemorrhage (aSAH) after having consumed cocaine recreationally were included. Variables such as mortality, vasospasm, seizures, re-bleeding, and complications were analyzed. RESULTS: After a thorough selection process, 14 studies involving 116,141 patients, of which 2227 had a history of cocaine consumption, were included in the analysis. There was a significant increase in overall unfavorable outcomes in aSAH patients with a history of cocaine use (OR 5.51 CI 95% [4.26-7.13] P = <0.0001; I2 = 78%), with higher mortality and poor neurologic outcomes. There were no significant differences in the risk of hydrocephalus, seizures, or re-bleeding. Cocaine use was found to increase the risk of vasospasm and overall complications. CONCLUSIONS: This study insinuates that cocaine use is associated with worse clinical outcomes in aSAH patients. Despite the cocaine users did not exhibit a higher risk of certain complications such as hydrocephalus and seizures, they had an increased risk of vasospasm and overall complications. These findings highlight the importance of addressing the issue of cocaine consumption as a primary preventive measure to decrease the incidence of aSAH and improve patient outcomes.

Global Neurosurgery Advances From Trenches to Bedside: Lessons From Neurosurgical Care in War, Humanitarian Assistance, and Disaster Response.

INTRODUCTION: War has influenced the evolution of global neurosurgery throughout the past century. Armed conflict and mass casualty disasters (MCDs), including Humanitarian Assistance Disaster Relief missions, require military surgeons to innovate to meet extreme demands. However, the military medical apparatus is seldom integrated into the civilian health care sector. Neurosurgeons serving in the military have provided a pragmatic template for global neurosurgeons to emulate in humanitarian disaster responses. In this paper, we explore how wars and MCD have influenced innovations of growing interest in the resource-limited settings of global neurosurgery. METHODS: We performed a narrative review of the literature examining the influence of wars and MCD on contemporary global neurosurgery practices. RESULTS: Wartime innovations that influenced global neurosurgery include the development of triage systems and modernization with airlifts, the implementation of ambulance corps, early operation on cranial injuries in hospital camps near the battlefield, the use of combat body armor, and the rise of damage control neurosurgery. In addition to promoting task-shifting and task-sharing, workforce shortages during wars and disasters contributed to the establishment of the physician assistant/physician associate profession in the USA. Low- and middle-income countries (LMICs) face similar challenges in developing trauma systems and obtaining advanced technology, including neurosurgical equipment like battery-powered computed tomography scanners. These challenges-ubiquitous in low-resource settings-have underpinned innovations in triage and wound care, rapid evacuation to tertiary care centers, and minimizing infection risk. CONCLUSION: War and MCDs have catalyzed significant advancements in neurosurgical care both in the pre-hospital and inpatient settings. Most of these innovations originated in the military and subsequently spread to the civilian sector as military neurosurgeons and reservist civilian neurosurgeons returned from the battlefront or other low-resource locations. Military neurosurgeons have utilized their experience in low-resource settings to make volunteer global neurosurgery efforts in LMICs successful. LMICs have, by necessity, responded to challenges arising from resource shortages by developing innovative, context-specific care paradigms and technologies.

Neurosurgery resident education in Ethiopia: a cross-sectional study, history, and future educational opportunities.

OBJECTIVE: An adequate healthcare workforce characterizes high-quality health systems. Sustainable domestic neurosurgery training is critical to developing a local neurosurgical workforce in low- and middle-income countries (LMICs). This study evaluated how neurosurgical training is delivered in Ethiopia, provides a historical narrative of neurosurgery training in the nation, and proposes future educational opportunities. METHODS: A mixed-methods design consisting of a semi-structured interview and a comprehensive survey was used to acquire data. The interview participants included neurosurgery program directors and faculty involved in resident education. The survey was sent to all current neurosurgery residents in Ethiopia. RESULTS: Ethiopian neurosurgical service began in 1970, and neurosurgical education started in 2006 with the establishment of the Addis Ababa University (AAU) residency program. The survey response rate was 86%, with 69 of 80 eligible neurosurgery residents responding. Most respondents were male (93%), aged 20-25 years (62%), and enrolled in the AAU program (61%). The oldest medical schools affiliated with tertiary hospitals were the top feeder institutions for neurosurgery training. Seventy-one percent of respondents worked for more than 60 hours/week, and 52% logged at least 100 cases annually. Survey responses demonstrated a critical need to establish subspecialty training and harmonize the national training curriculum. CONCLUSIONS: The history of Ethiopian neurosurgery training exemplifies how global neurosurgery efforts focused on capacity building can rapidly expand the local neurosurgical workforces of LMICs. Opportunities for neurosurgical education require initiatives promoting a subspecialized, diverse workforce that attains both the clinical and academic proficiency necessary for advancing neurosurgical care locally and globally.

Reducing the Gap in Neurosurgical Education in LMICs: A Report of a Non-Profit Educational Program.

INTRODUCTION: Central to neurosurgical care, neurosurgical education is particularly needed in low- and middle-income countries (LMICs), where opportunities for neurosurgical training are limited due to social and economic constraints and an inadequate workforce. The present paper aims (1) to evaluate the validity and usability of a cadaver-free hybrid system in the context of LMICs and (2) to report their learning needs and whether the courses meet those needs via a comprehensive survey. METHODS: From April to November 2021, a non-profit initiative consisting of a series of innovative cadaver-free courses based on virtual and practical training was organized. This project emerged from a collaboration between the Young Neurosurgeons Forum of the World Federation of Neurological Societies (WFNS), the NIHR Global Health Research Group on Neurotrauma, and UpSurgeOn, an Italian hi-tech company specialized in simulation technologies, creator of the UpSurgeOn Box, a hyper-realistic simulator of cranial approaches fused with augmented reality. Over that period, 11 cadaver-free courses were held in LMICs using remote hands-on Box simulators. RESULTS: One hundred sixty-eight participants completed an online survey after course completion of the course. The anatomical accuracy of simulators was overall rated high by the participant. The simulator provided a challenging but manageable learning curve, and 86% of participants found the Box to be very intuitive to use. When asked if the sequence of mental training (app), hybrid training (Augmented Reality), and manual training (the Box) was an effective method of training to fill the gap between theoretical knowledge and practice on a real patient/cadaver, 83% of participants agreed. Overall, the hands-on activities on the simulators have been satisfactory, as well as the integration between physical and digital simulation. CONCLUSIONS: This project demonstrated that a cadaver-free hybrid (virtual/hands-on) training system could potentially participate in accelerating the learning curve of neurosurgical residents, especially in the setting of limited training possibilities such as LMICs, which were only worsened during the COVID-19 pandemic.

The AANS Harvey Cushing Medal: a demographic and academic analysis of its recipients.

Background: The Harvey Cushing Medal, awarded by the American Association of Neurological Surgeons, is the premier accolade in neurosurgery. The study's purpose was to examine the qualities and accomplishments of previous winners, emphasizing potential selection biases, with the aim to promote social justice and guide young neurosurgeons in their career paths. Results: Predominantly, recipients graduated from top-ranked United States News and World Report institutions and specialized in cerebrovascular and neuro-oncologic/skull base neurosurgery. A significant proportion held roles as department or division chairs and led neurosurgical organizations. All awardees were male, and there was a notable trend of increasing publication counts among more recent recipients. Conclusions: Commonalities among Harvey Cushing Medal winners include graduating from top institutions, holding significant leadership roles, and having an extensive publication history. However, the absence of female and underrepresented minority awardees underscores an urgent need for greater diversity in the selection process.

Needs, Roles, and Challenges of Young Asian Neurosurgeons.

BACKGROUND: Asia has a marked shortage of neurosurgical care, with approximately 2.5 million critical cases left untreated. The Young Neurosurgeons Forum of the World Federation of Neurosurgical Societies surveyed Asian neurosurgeons to identify research, education, and practice. METHODS: A cross-sectional study using a pilot-tested e-survey was circulated to the Asian neurosurgical community from April to November 2018. Descriptive statistics were used to summarize variables pertaining to demographics and neurosurgical practices. The chi-square test was used to explore the relationship between World Bank income level and variables on neurosurgical practices. RESULTS: A total of 242 responses were analyzed. Respondents were mostly from the low- and middle-income countries (70%). Most represented institutions were teaching hospitals (53%). More than 50% of the hospitals had between 25and 50 neurosurgical beds. Access to an operating microscope (P = 0.038) or image guidance system (P = 0.001) appeared to increase in correlation to a higher World Bank income level. Limited opportunities for conducting research (56%) and hands-on operating opportunities (45%) were leading challenges in daily academic practice. The leading challenges were limited numbers of intensive care unit beds (51%), inadequate or absent insurance coverage (45%), and lack of organized perihospital care (43%). Inadequate insurance coverage decreased with increasing World Bank income levels (P < 0.001). Organized perihospital care (P = 0.001), regular magnetic resonance imaging access (P = 0.032), and equipment necessary for microsurgery (P = 0.007) increased with higher World Bank income levels. CONCLUSIONS: Improving neurosurgical care hinges on regional and international collaboration and national policies to ensure universal access to essential neurosurgical care.

Authorship Disparities in International Neurosurgical Research Collaborations: A Bibliometric Analysis.

BACKGROUND: Research is pivotal to neurosurgical training and practice. The objectives of this study were to quantify neurosurgical research output by authors from low-income countries (LICs), using author affiliation as a proxy, and to understand the patterns of collaboration between LIC authors and their international partners. METHODS: PubMed, CINAHL, and EMBASE were searched for neurosurgical literature published by authors from the 27 World Bank LICs from 2010 to 2020. These articles were screened for relevance. Information about publication type, study design, and author demographics was then extracted from included articles. Scopus was subsequently used to determine the H-indices of the authors. RESULTS: The rate at which LIC authors have been publishing neurosurgical research has increased significantly from 2010 to 2020. Overall, 19 of the 27 LICs were represented. The LICs with the most research output includes Uganda, Ethiopia, and Rwanda. When LIC authors collaborated with authors from middle-or-high-income countries, these LIC researchers were solely listed in a middle authorship position more than 70% of the time. On average, the H-index of LIC authors was 4.9, compared with average H-indices of 8.7 and 16.8 for their MIC and HIC collaborators, respectively. CONCLUSIONS: The positioning of LIC researchers as middle author contributors revealed significant authorship disparities in international neurosurgical research collaborations. The average H-indices of authors from middle-or-high-income countries were more than 3 times greater than those of LIC authors. Quantifying this issue allows neurosurgical organizations to understand the current landscape and to set concrete goals for research capacity building in LICs.

Needs, Roles, and Challenges of Young Latin American and Caribbean Neurosurgeons.

BACKGROUND: Barriers to neurosurgery training and practice in Latin American and Caribbean countries (LACs) have been scarcely documented. The World Federation of Neurosurgical Societies Young Neurosurgeons Forum survey sought to identify young neurosurgeons' needs, roles, and challenges. We present the results focused on Latin America and the Caribbean. METHODS: In this cross-sectional study, we analyzed the Young Neurosurgeons Forum survey responses from LACs, following online survey dissemination through personal contacts, social media, and neurosurgical societies' e-mailing lists between April and November 2018. Data analysis was performed using Jamovi version 2.0 and STATA version 16. RESULTS: There were 91 respondents from LACs. Three (3.3%) respondents practiced in high-income countries, 77 (84.6%) in upper middle-income countries, 10 (11%) in lower middle-income countries, and 1 (1.1%) in an unclassified country. The majority (77, or 84.6%) of respondents were male, and 71 (90.2%) were younger than 40. Access to basic imaging modalities was high, with access to computed tomography scan universal among the survey respondents. However, only 25 (27.5%) of respondents reported having access to imaging guidance systems (navigation), and 73 (80.2%) reported having access to high-speed drills. A high GDP per capita was associated with increased availability of high-speed drills and more time dedicated to educational endeavors in neurosurgery, such as didactic teaching and topic presentation (P < 0.05). CONCLUSIONS: This survey found that neurosurgery trainees and practitioners of Latin America and the Caribbean face many barriers to practice. These include inadequate state-of-the-art neurosurgical equipment, a lack of standardized training curricula, few research opportunities, and long working hours.

Global Neurosurgery: Progress and Resolutions at the 75th World Health Assembly.

Neurosurgical advocates for global surgery/neurosurgery at the 75th World Health Assembly gathered in person for the first time after the COVID-19 pandemic in Geneva, Switzerland, in May 2022. This article reviews the significant progress in the global health landscape targeting neglected neurosurgical patients, emphasizing high-level policy advocacy and international efforts to support a new World Health Assembly resolution in mandatory folic acid fortification to prevent neural tube defects. The process of developing global resolutions through the World Health Organization and its member states is summarized. Two new global initiatives focused on the surgical patients among the most vulnerable member states are discussed, the Global Surgery Foundation and the Global Action Plan on Epilepsy and other Neurological Disorders. Progress toward a neurosurgery-inspired resolution on mandatory folic acid fortification to prevent spina bifida-folate is described. In addition, priorities for moving the global health agenda forward for the neurosurgical patient as it relates to the global burden of neurological disease are reviewed after the COVID-19 pandemic.

Historical determinants of neurosurgical inequities in Africa and the African diaspora: A review and analysis of coloniality.

The movement to decolonize global health challenges clinicians and researchers of sub-disciplines, like global neurosurgery, to redefine their field. As an era of racial reckoning recentres the colonial roots of modern health disparities, reviewing the historical determinants of these disparities can constructively inform decolonization. This article presents a review and analysis of the historical determinants of neurosurgical inequities as understood by a group of scholars who share Sub-Saharan African descent. Vignettes profiling the colonial histories of Cape Verde, Rwanda, Cameroon, Ghana, Brazil, and Haiti illustrate the role of the colonial legacy in the currently unmet need for neurosurgical care in each of these nations. Following this review, a bibliographic lexical analysis of relevant terms then introduces a discussion of converging historical themes, and practical suggestions for transforming global neurosurgery through the decolonial humanism promulgated by anti-racist practices and the dialogic frameworks of conscientization.

Current Neurosurgical Care in Ethiopia Using the Lens of the Lancet Global Health Commission on High-Quality Health Systems.

BACKGROUND: Neurosurgery is a rapidly developing specialty in Ethiopia. Previous global neurosurgery studies have highlighted the need for synchronizing workforce increase with improving quality, access, and capacity to provide neurosurgical care. OBJECTIVE: To evaluate Ethiopia's neurosurgical system and highlight the critical interventions required for the sustained development of Ethiopian neurosurgery as part of a high-quality health system (HQHS). METHODS: A comprehensive survey was sent to all practicing neurosurgeons. Public databases on Ethiopian census reports and current road infrastructure were used for spatial analysis of neurosurgical access. RESULTS: The survey response rate was 90% (45/50). Most respondents were men (95.6%), aged 30 to 40 years (82%), who worked at national referral hospitals (71%). The reported annual caseload per practicing neurosurgeon was >150 cases for 40% of urban and 20% of rural neurosurgeons. Head and spine neurotrauma and tumors were the most common neurosurgical indications. Computed tomography scanner was the most widely available diagnostic equipment (62%). 76% of respondents indicated the presence of postoperative rehabilitation care at their institutions. Thirteen percent and 27% of the nation lived within a 2-hour and 4-hour driving distance from a neurosurgical center, respectively. CONCLUSION: The results highlight the need for vital improvements in neurosurgical capacity to sustain progress toward HQHS. Promoting sustained development in all components of HQHS can be achieved by diversifying the workforce and training residency candidates committed to practicing in underserved regions. Additional strategies might include establishing a national registry for neurosurgical data and implementing policy changes conducive to improving perihospital care and other health system components.

Breaking boundaries through Doctors Reaching Minority Men Exploring Neuroscience: a mentorship model to foster a pipeline for underrepresented minorities.

OBJECTIVE: In 2015, the Association of American Medical Colleges report titled "Altering the Course: Black Males in Medicine" showed a decline in the number of Black men matriculating into medical school. To alter this trend, the authors' hypothesis was that formally exposing Black men to the clinical neurosciences during high school would enhance their chances of entering the physician workforce. For this reason, in 2007, the Doctors Reaching Minority Men Exploring Neuroscience (DR. MMEN) program was established at the Icahn School of Medicine at Mount Sinai. The program aimed to provide early exposure, mentorship, and inspiration to high school-age Black and Latinx men. The aim of this study was to evaluate the impact of the DR. MMEN program in the context of the recent race and ethnicity trends among medical school matriculants (MSMs). METHODS: Association of American Medical Colleges data on MSMs stratified by race and ethnicity were reviewed for the period between 2015 and 2020. Data pertinent to the academic achievements of DR. MMEN participants, such as matriculation to college and/or medical school, were prospectively tracked and incorporated with mixed-methods exit assessment data. Qualitative responses were coded and analyzed using a thematic concept analysis method. RESULTS: Over the study period, the increase of MSMs in the US was 1.0% and 1.7% for Black and Latinx individuals, respectively. Changes for the male MSM cohort were negligible: 0.3% for Black and 0.7% for Latinx. With respect to DR. MMEN, 42% of participants from 2017 to 2019 earned college scholarships, and 25% of students from the 2017-2018 cohort matriculated to a combined college-medical program. Survey data showed that 100% of DR. MMEN participants found the program useful. Analysis of qualitative data revealed that participants considered pursuing a career in neurosurgery or in another medical field. Diligence and a passion for medicine were identified as the top two most important lessons in the program, and witnessing patient satisfaction and observing a neurosurgery operation were described as the most important experiences. Participants considered availability to give advice and feedback and a passion for teaching as the principal attributes of their mentors. CONCLUSIONS: Over the past 6 years, the slight increase in Black and Latinx MSMs has not been significant enough to remedy ethnoracial disparities among MSMs. In particular, Black male matriculation to medical school has remained stagnant. The DR. MMEN program is a promising model to inspire young scholars and improve diversity within neuroscience and medicine at large.

International Survey of Antiseizure Medication Use in Patients with Complicated Mild Traumatic Brain Injury: A New York Neurotrauma Consortium Study.

BACKGROUND: Seizures and epilepsy after traumatic brain injury (TBI) negatively affect quality of life and longevity. Antiseizure medication (ASM) prophylaxis after severe TBI is associated with improved outcomes; these medications are rarely used in mild TBI. However, a paucity of research is available to inform ASM use in complicated mild TBI (cmTBI) and no empirically based clinical care guidelines for ASM use in cmTBI exist. We aim to identify seizure prevention and management strategies used by clinicians experienced in treating patients with cmTBI to characterize standard care and inform a systematic approach to clinical decision making regarding ASM prophylaxis. METHODS: We recruited a multidisciplinary international cohort through professional organizational listservs and social media platforms. Our questionnaire assessed factors influencing ASM prophylaxis after cmTBI at the individual, institutional, and health system-wide levels. RESULTS: Ninety-two providers with experience managing cmTBI completed the survey. We found a striking diversity of ASM use in cmTBI, with 30% of respondents reporting no/infrequent use and 42% reporting frequent use; these tendencies did not differ by provider or institutional characteristics. Certain conditions universally increased or decreased the likelihood of ASM use and represent consensus. Based on survey results, ASMs are commonly used in patients with cmTBI who experience acute secondary seizure or select positive neuroimaging findings; we advise caution in elderly patients and those with concomitant neuropsychiatric illness. CONCLUSIONS: This study is the first to characterize factors influencing clinical decision making in ASM prophylaxis after cmTBI based on multidisciplinary multicenter provider practices. Prospective controlled studies are necessary to inform standardized guideline development.
