The Governance of Helmet Safety to Prevent Traumatic Brain Injury in the Caribbean.

BACKGROUND: The Caribbean is a unique region of islands and cays home to nearly 43 million people. A significant challenge facing this population is the burden of traumatic brain injury, which disproportionately affects younger individuals and carries a significant economic burden. A preventive measure to reduce this burden is consistent wearing of helmets. This study aims to assess TBI prevention through helmet safety in Caribbean nations in order to demonstrate the regional impact of public health solutions. METHODS: We assess the member states of the Caribbean Community (CARICOM) and sought to evaluate CARICOM nations' TBI prevention through helmet safety with relation to public health, policy, laws, infrastructure, and regulations. We produced the Rolle Scoring System (RSS) to ascertain the influence of governance around helmet safety for TBI prevention. The RSS aims to provide a quantifiable method of how well a CARICOM nation is performing in efforts to reduce TBI. The RSS is broken down into 2 categories, with scores ranging from 1 (worst) to 5 (best). The range of possible scores a CARICOM nation could receive was 8 to 40. RESULTS: Fourteen CARICOM nations were ultimately incorporated into our analysis. From the initial cohort, 3 were removed. These nations were Anguilla, Saint Kitts & Nevis, and Montserrat. We analyzed values derived from the RSS, finding a mean Rolle score of 22. We further subdivided the nations into low Rolle score (8-24) and high Rolle score (>24). Trinidad and Tobago had the highest Rolle score at 29. Haiti was found to have the lowest Rolle score at 8. CONCLUSION: Several Caribbean nations have demonstrated leadership pertaining to TBI prevention through helmet safety. The regional momentum of helmet safety in the Caribbean can serve as a model for other geographical regional blocs that share interests and culture to consider comprehensive approaches to public health challenges.

The Experience of Survivors of Firearm Suicide Attempts: A Retrospective Case Series.

Objective: We sought to identify people who survived firearm suicide attempts to describe the acute stressors, substance use, and mental health conditions related to the attempt. Background: Most firearm deaths in the United States are the result of suicide. Because firearm suicide attempts have a case fatality rate of approximately 90%, little is known about the precipitating factors that lead to firearm suicide attempts. Methods: We conducted a retrospective case series of patients admitted to a large hospital system between 2000 and 2019 who survived intentional, self-inflicted gunshot wounds to the head. Through the electronic medical record, we collected information about acute stressors, substance use, and mental health diagnoses before or at the time of the suicide attempt. Results: Thirty-four patients were included in the study cohort. Patients were predominantly White (74%) and male (88%), with a mean age of 44 (range, 14-82). Nineteen (56%) patients were acutely intoxicated with alcohol upon hospitalization and 17 (50%) patients had a positive urine drug screen. Acute stressors involving interpersonal relationships (53%), work/school (32%), and legal disputes (18%), among others, were documented in 82% of patients. Most patients (65%) had been diagnosed with depression before their index hospitalization. Most patients were discharged to an acute rehabilitation center (41%) or an inpatient psychiatric facility (41%). Conclusions: Acute stress and alcohol intoxication were common in this cohort of patients who attempted suicide using firearms. These data offer an ability to learn from the experience of survivors of firearm suicide attempts, a rare population.

The impact of traumatic brain injury on economic productivity in the Caribbean.

Introduction: Traumatic brain injury (TBI) is a significant cause of morbidity and mortality in the Caribbean as well as globally. Within the Caribbean, the prevalence of TBI is approximately 706 per 100,000 persons - one of the highest rates per capita in the world. Research question: We aim to assess the economic productivity lost due to moderate to severe TBI in the Caribbean. Material and methods: The annual cost of economic productivity lost in the Caribbean from TBI was calculated from four variables: (1) the number of people with moderate to severe TBI of working age (15-64 years), (2) the employment-to-population ratio, (3) the relative reduction in employment for people with TBI, and (4) per capita Gross Domestic Product (GDP). Sensitivity analyses were performed to evaluate whether the uncertainty of the TBI prevalence data result in substantive changes in the productivity losses. Results: Globally, there was an estimated 55 million (95% UI 53, 400, 547 to 57, 626, 214) cases of TBI in 2016 of which 322,291 (95% UI 292,210 to 359,914) were in the Caribbean. Using GDP per capita, we calculated the annual cost of potential productivity losses for the Caribbean to be $1.2 billion. Discussion and conclusion: TBI has a significant impact on economic productivity in the Caribbean. With upwards of $1.2 billion lost in economic productivity from TBI, there is an urgent need for appropriate prevention and management of this disease by upscaling neurosurgical capacity. Neurosurgical and policy interventions are necessary to ensure the success of these patients in order to maximize economic productivity.

Analysis of the Caribbean Neurosurgery Workforce: Scope of Practice, Challenges, and Ways Forward.

BACKGROUND: The neurosurgical workforce in the Caribbean and surrounding countries is largely unknown due to the diversity in cultural, linguistic, political, financial disparities, and colonial history between the countries. About 45 neurosurgeons serve 16 million people in the Caribbean Community and Common Market, a trade alliance including most Caribbean nations. We aimed to understand the current scope of neurosurgical workforce in this region while highlighting any system challenges and potential solutions for upscaling the workforce. METHODS: We surveyed neurosurgeons within Caribbean countries and surrounding countries online using qualitative and quantitative methods via Qualtrics. RESULTS: Of the 38 countries within the Caribbean and surrounding countries, 26 (68%) were surveyed and of which 18 (69%) replied. In total, 172 regional neurosurgeons were identified, of which 61 (35%) replied-with a majority of general neurosurgeons (56%). Remarkably, the majority of countries failed to meet the threshold workforce density for safe health care-either expressed by full-time equivalent neurosurgeons or neurosurgical centers (see table). Most neurosurgical practices confirmed receiving or sending medical referrals. If so, most referrals took longer than 8 hours without significant difference regarding the destination. Lastly, challenges confronting neurosurgical advancement were found in the following: technology and equipment (40%), trained personnel (31%), hospital or medical center infrastructure (14%), neurosurgical education, and training (44%). CONCLUSIONS: To our knowledge, this is the first qualitative and quantitative study exploring the current status of the neurosurgical workforce within the Caribbean and surrounding countries. Identifying resources and challenges can contribute to improving regionalized neurosurgical care.

Time to Care: Analysis of Time Differences and Outcomes in the Management of Pediatric Traumatic Brain Injury for a High-Income and Lower-Middle-Income Country.

BACKGROUND: Pediatric cranial trauma is the leading cause of acquired death and disability in children worldwide. However, trauma resources vary widely among countries. We sought to compare management and timely access to care between a level 1 U.S. pediatric trauma center and a tertiary referral hospital in a lower-middle-income country to assess whether system and resource differences influence care and outcomes. METHODS: We compared data from 214 pediatric head trauma admissions to Philippine General Hospital (Manila) with 136 children from the TRACK-TBI pediatrics study cohort at Massachusetts General Hospital (MGH). Admitted MGH patients were compared with the Philippine cohort regarding demographics; mechanism of injury; times to neurosurgical consult, imaging, and surgery; in-hospital mortality; and length of hospitalization. RESULTS: Age (9 years), gender distribution (67% male), and presenting Glasgow Coma Scale scores were similar (P = 0.10) between sites. More children had intracranial injury in the Philippine cohort (73% vs. 60%; n = 319) and more underwent neurosurgery (27% vs. 4%). Times to consult, imaging, and surgery were longer in the Philippines (12.3 vs. 6.5, 12.0 vs. 2.8, and 45.4 vs. 5.6 hours, respectively). In-hospital mortality across all admissions was similar between cohorts (3% vs. 0%; P = 0.09), but significantly higher in the most severe Philippines cases (31% vs. 0%, P=0.04). Length of stay was longer (5 vs. 2 days; P < 0.001) in the Philippine cohort. CONCLUSIONS: High-income country status correlated with faster care, shorter hospitalizations, and better outcomes among severe cases. Prompt care through sophisticated trauma system implementation may improve pediatric health in resource-limited settings.

Racial and Social Determinants of Civilian Gunshot Wounds to the Head.

Objective: To assess the clinical, racial, and social characteristics of victims of Gunshot wounds (GSWs) to the head and assess for associations between these factors and outcomes. Summary Background Data: Previous literature has not focused on the association of race and socioeconomic factors with these specific injuries. Methods: We identified patients with GSWs to the head who presented to 2 urban academic medical centers between 1998 and 2020, and extracted patient-level demographic data, information about the clinical and surgical course, and outcomes at discharge and follow-up. Results: The cohort included 250 patients, 90% (n = 226) of whom were male, with a mean age of 28 years. Forty-five percent were white (n = 112), 19% Black (n = 48), 18% Latinx (n = 45), with 6% "other" (n = 16), and 12% "unknown" (n = 29). The majority of patients presented with assault-related trauma (n = 153, 61%) as compared to self-inflicted injuries (n = 97, 39%). Across the entire cohort, sex, age, race, and median income by ZIP code were not significant predictors of outcome. Victims of assault by GSW to the head were more likely to be age 18 or younger (OR 5.26, P = 0.01), between the ages of 19 and 33 years (OR 4.7, P = 0.001), Black (OR 6.66, P < .001), and Latinx (OR 2.65, P = 0.03). Most patients (n = 155, 63%) had a poor functional outcome (modified Rankin Score 3-6) at discharge. Conclusion: Age, race, and income status were not independent predictors of mortality or functional outcome at discharge in our population. Assault-related GSWs to the head mostly involved young Black or Latinx men of lower socioeconomic status, while self-inflicted injuries were largely seen in older white men.

Implementing a Neurotrauma Registry in Latin America and the Caribbean.

Background Traumatic brain injury (TBI) has a disproportionately greater impact in low- and middle-income countries (LMICs). One strategy to reduce the burden of disease in LMICs is through the implementation of a trauma registry that standardizes the assessment of each patient's management of care. Objective This study aims to ascertain the interest of Latin America and the Caribbean (LAC) nations in establishing a shared neurotrauma registry in the regional block, based on an existing framework for collaboration. Methods A descriptive review was performed regarding the interests of LAC nations in implementing a shared neurotrauma registry in their region. We convened a meeting with seven Caribbean and five Latin American nations. Results One hundred percent ( n = 12) of the LAC representatives including neurosurgeons, neurointensivists, ministers of health, and chief medical officers/emergency medical technicians (EMTs) agreed to adopt the registry for tracking the burden of TBI and associated pathologies within the region. Conclusion The implementation of a neurotrauma registry can benefit the region through a shared database to track disease, improve outcomes, build research, and ultimately influence policy.

Qualitative and Quantitative Analysis of Pediatric Post Neurosurgical Care in a Lower Middle-Income Country: The Zambian Experience.

OBJECTIVE: Pediatric postoperative neurosurgical care is an essential component of a child's treatment pathway. It is important to better understand how neurosurgeons in lower middle-income countries (LMICs) have been able to address socioeconomic and systemic factors to improve their patients' access to quality pediatric postoperative neurosurgical care. We aim to characterize the pediatric neurosurgical postoperative system in place in Zambia and to discuss how these efforts have been implemented to improve outcomes and address socioeconomic barriers to accessing health care. METHODS: We acquired a patient list of 90 tenants of House of Hope (HOH)-an out-of-hospital center caring for children awaiting surgery, as well as those recovering from surgery. Of the patient list, 44 patients qualified for our study. Survey responses and occurrence of demographic and clinical characteristics were calculated. Non-normally distributed variables (age) were reported by median and interquartile range (IQR). Dichotomous variables were presented as percentages. Fisher's Exact test was applied to compare categorical data and hospital re-admission. A P-value of <0.05 was considered significant. RESULTS: Our study demonstrates two key findings: (1) low 30-day hospital re-admission rate of 9% and (2) favorable postoperative experience by patient families. Of the 44 patients, a majority were 1-year-old children (n = 31, 70%) and female (n = 24, 55%) (IQR 1-2 years). Presenting conditions included: hydrocephalus only (n = 35, 80%), hydrocephalus and myelomeningocele (n = 5, 11%), myelomeningocele only (n = 2, 5%), cerebral palsy (n = 1, 2%), and encephalocele (n = 1, 2%). Half (n = 22, 50%) of the patients lived in east Zambia, 8 (18%) lived in central, 8 (18%) in north, 5 (11%) in south, and 1 (2%) in west Zambia. CONCLUSIONS: We report the first qualitative and quantitative analysis of postoperative care for LMIC pediatric neurosurgical patients in the academic literature. Quality, patient-centered postoperative pediatric neurosurgical care that is rooted in addressing socioeconomic determinants of health produces good outcomes in LMICs.

Timely Access to Neurosurgical Care in the Caribbean Using Geospatial Analysis.

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.

Global Neurosurgery Education in United States Residency Programs.

BACKGROUND: Global neurosurgery encompasses the social and surgical practices that effect the neurologic health of vulnerable and underserved populations in domestic and international resource-limited settings. Formal academic engagement in global neurosurgery is limited in residency programs. Here we explore the current status of global neurosurgery education in residency programs across the United States. METHODS: We contacted 115 Accreditation Council for Graduate Medical Education-accredited residency programs in the United States to complete an 8-question electronic survey on global neurosurgery education. Questions were framed with binary "yes" or "no" answers to indicate presence of a global health activity. Respondents provided additional information if desired. Global education activity was categorized based on the number of resources attributed to global health activities: low (0-2), moderate (3-5), or high (6-8). RESULTS: Thirty-four residency programs completed the survey (29.6%). The majority of respondents reported offering funding for research and educational opportunities in global neurosurgery (n = 22). Programs tended to support global neurosurgery conferences (n = 20), periodic dedicated lectures (n = 15), and rotations in resource-constrained or marginalized communities domestically or abroad (n = 15). Some programs offer continuity clinics in marginalized settings (n = 10), supplementary reading material (n = 8), core curricula (n = 6), or a designated residency track in global neurosurgery (n = 3). The majority of residency programs had low-level engagement in global neurosurgery (n = 18), with only 3 programs having high levels of engagement. CONCLUSIONS: Formal global neurosurgery training is limited within US residency programs. With rising trends in the neurosurgical disease burden globally, it may benefit residency programs to develop training paths to equip the next generation of neurosurgeons to address such needs.
