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.

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.

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.

The unmet global burden of cranial epidural hematomas: A systematic review and meta-analysis.

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.

Global neurosurgical workforce density-you cannot improve what you do not measure.

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.

Safety and efficacy of cement augmentation with fenestrated pedicle screws for tumor-related spinal instability.

OBJECTIVE: Achieving rigid spinal fixation can be challenging in patients with cancer-related instability, as factors such as osteopenia, radiation, and immunosuppression adversely affect bone quality. Augmenting pedicle screws with cement is a strategy to overcome construct failure. This study aimed to assess the safety and efficacy of cement augmentation with fenestrated pedicle screws in patients undergoing posterior, open thoracolumbar surgery for spinal metastases. METHODS: A retrospective review was performed for patients who underwent surgery for cancer-related spine instability from 2016 to 2019 at the Massachusetts General Hospital. Patient demographics, surgical details, radiographic characteristics, patterns of cement extravasation, complications, and prospectively collected Patient-Reported Outcomes Measurement Information System Pain Interference and Pain Intensity scores were analyzed using descriptive statistics. Logistic regression was performed to determine factors associated with cement extravasation. RESULTS: Sixty-nine patients underwent open posterior surgery with a total of 502 cement-augmented screws (mean 7.8 screws per construct). The median follow-up period for those who survived past 90 days was 25.3 months (IQR 10.8-34.6 months). Thirteen patients (18.8%) either died within 90 days or were lost to follow-up. Postoperative CT was performed to assess the instrumentation and patterns of cement extravasation. There was no screw loosening, pullout, or failure. The rate of cement extravasation was 28.9% (145/502), most commonly through the segmental veins (77/145, 53.1%). Screws breaching the lateral border of the pedicle but with fenestrations within the vertebral body were associated with a higher risk of leakage through the segmental veins compared with screws without any breach (OR 8.77, 95% CI 2.84-29.79; p < 0.001). Cement extravasation did not cause symptoms except in 1 patient who developed a symptomatic thoracic radiculopathy requiring decompression. There was 1 case of asymptomatic pulmonary cement embolism. Patients experienced significant pain improvement at the 3-month follow-up, with decreases in Pain Interference (mean change 15.8, 95% CI 14.5-17.1; p < 0.001) and Pain Intensity (mean change 28.5, 95% CI 26.7-30.4; p < 0.001). CONCLUSIONS: Cement augmentation through fenestrated pedicle screws is a safe and effective option for spine stabilization in the cancer population. The risk of clinically significant adverse events from cement extravasation is very low.

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.
