Effect of perioperative anticoagulant prophylaxis in patients with traumatic subdural hematoma and a history of anticoagulant use: a propensity-matched National Trauma Data Bank analysis.

OBJECTIVE: The use of anticoagulation to prevent venous thromboembolism (VTE) is controversial in the setting of neurosurgical decompression for traumatic subdural hematoma (SDH). In these patients, there is concern that anticoagulation may cause secondary hemorrhage, increasing the risk of death and other complications. Patients with a history of anticoagulant use are at further risk of VTE, but the effect of VTE prophylaxis (VTEP) following neurosurgery for SDH has not been thoroughly investigated in this population. This study aims to investigate the differences in in-hospital outcomes in patients with SDH and preexisting anticoagulant use who received VTEP following neurosurgical intervention compared with those who did not. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for all patients with preexisting anticoagulant use presenting with an SDH who subsequently underwent neurosurgical intervention. Patients who received VTEP were propensity score matched with patients who did not based on demographics, insurance type, injury severity, and comorbidities. Paired Student t-tests, Pearson's chi-square tests, and Benjamini-Hochberg multiple comparisons correction were used to compare differences in in-hospital complications, length of stay (LOS), and mortality rate between the two groups. A logistic regression model was developed to identify risk factors for in-hospital mortality. RESULTS: Two thousand seven hundred ninety-four patients matching the inclusion criteria were identified, of whom 950 received VTEP. Following one-to-one matching and multiple comparisons correction, the VTEP group had a lower mortality rate (18.53% vs 34.53%, p < 0.001) but longer LOS (14.09 vs 8.57 days, p < 0.001) and higher rates of pressure ulcers (2.11% vs 0.53%, p = 0.01), unplanned intensive care unit admission (9.05% vs 3.47%, p < 0.001), and unplanned intubation (9.47% vs 6.11%, p = 0.021). The multivariable logistic regression showed that use of unfractionated heparin (UH; OR 0.36, p < 0.001) and low-molecular-weight heparin (LMWH; OR 0.3, p < 0.001) were associated with lower odds of in-hospital mortality. CONCLUSIONS: In patients with traumatic SDH and a history of anticoagulant use, perioperative VTEP was associated with increased LOS but provided a mortality benefit. LMWH and UH use were the strongest predictors of survival.

Racial disparities in incidence, treatment, and survival in adult brain metastases: a 10-year national database analysis.

OBJECTIVE: The aim of this study was to assess demographic and racial disparities in incidence, treatment, and survival of adults with metastatic malignancy to the brain. METHODS: Using the Surveillance, Epidemiology, and End Results (SEER) Program database, the authors identified adults with nonprimary brain metastases between 2010 and 2019. Incidence was calculated for all 10 years while data from 2010 to 2014 were used for survival analysis. The primary outcome measure was all-cause mortality within 5 years, assessed by 6-month, 1-year, 2-year, and 5-year survival rates. Chi-square tests of independence and one-way ANOVA were used to compare categorical and continuous measures, respectively, between non-Hispanic White (NHW), Hispanic White (HW), Black, and Asian/Pacific Islander (API) patients. A multivariable Cox proportional hazards model was developed to evaluate the risk of death within 5 years. RESULTS: A total of 64,690 patient records were identified and analyzed following exclusion based on age (patients > 84 years or < 18 years were excluded), missing race data, and missing survival data. Incidences are reported per 100,000 adults. The incidence of brain metastases increased from 2.59 in 2010 to 2.78 in 2019, with an average 10-year incidence of 2.72. API patients had the highest population-adjusted incidence (3.52), followed by NHW (2.99), Black (2.32), and HW (1.59) patients. Black patients were the most likely to have low income and single status, while API patients were the most likely to have high income and married status. Subsequently, Black patients had the shortest survival time (9.05 months vs 9.19 months for NHW vs 12.93 months for HW vs 15.89 months for API patients, p < 0.001). After controlling for the effect of socioeconomic factors on survival, the multivariable analysis showed that Black (HR 0.91, 95% CI 0.88-0.94), HW (HR 0.73, 95% CI 0.69-0.76), and API (HR 0.69, 95% CI 0.66-0.73) patients all had a survival advantage compared with NHW patients. Surgery also conferred a strong survival advantage (HR 0.47, 95% CI 0.44-0.49). CONCLUSIONS: The incidence of brain metastases has increased slightly between 2010 and 2019, with the highest rate in API patients. Black patients had the lowest survival, potentially due to poor socioeconomic status and lower rates of surgery and chemotherapy. Black patients were the most likely to not be recommended surgery, suggesting a discrepancy in services offered to these patients. More research is warranted to understand the underlying causes of these disparities.

Characteristics of work-related spine injury in the USA: a National Trauma Data Bank analysis.

PURPOSE: Workplace injury is a commonplace occurrence in the USA. Spine injuries are especially devastating as they can cause chronic pain and limit mobility which prevents patients from returning to work. Gaining a better understanding of the patients, mechanisms, and treatments associated with these injuries can aid in improving outcomes. The purpose of this study is to characterize the nature of work-related spine injuries. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for all diagnoses involving the cervical, thoracic, lumbar, and sacral spine. Patient demographics, comorbidities, injury characteristics, spinal diagnoses, and procedures were identified for each occupation. Occupational industries, patient demographics, mechanisms of injury, diagnoses, and spinal procedures were characterized. RESULTS: A total of 100,842 work-related injuries were identified between 2017 and 2019. Of those, 19,002 (19%) were spine injuries, and subsequently, 3963 (21%) required spinal surgery. Eight thousand twenty-nine (42%) cases were seen among construction workers, which had the highest proportion of Hispanic patients (36%). Smoking was prevalent in labor-intensive occupations with high rates of spine injury such as building and grounds maintenance. The most common mechanism of injury was a fall from a roof. The most common injury diagnoses were L1, L2, and L3 fractures, and the most common procedures were T12-L1 fusion, multilevel thoracic fusion, and multilevel lumbar fusion. CONCLUSION: Spine injuries represent a significant portion of work-related injuries in the USA and a considerable portion require neurosurgical intervention. Initial efforts should focus on the prevention and management of lumbar spine injuries in the construction industry.

Surgical Outcomes in Octogenarians with Central Cord Syndrome: A Propensity-Score Matched Analysis.

OBJECTIVE: Central cord syndrome (CCS) is a traumatic cervical spine injury that is treated with surgical decompression. In octogenarians (80-89), surgeons often opt for conservative management instead due to fears of postoperative complications and prolonged recovery times. This study aims to assess the in-hospital complications and outcomes in octogenarians undergoing surgery compared to those undergoing nonsurgical management for CCS. METHODS: The National Trauma Data Bank was queried from 2017 to 2019 for octogenarians with CCS. Patients who received surgical fusion or decompression were divided into the surgery group and the remaining into the nonsurgical group. The surgery group was sampled and propensity score matched with the non-surgery group. Student t tests and Pearson χ2 tests were used to test for group differences. RESULTS: A total of 759 octogenarians with CCS were identified. Following sampling and propensity score matching, 225 patients were identified in each group. The surgery group experienced longer intensive care unit (6.8 days vs. 3.21 days, P < 0.001) and hospital (13.79 days vs. 7.8 days, P < 0.001) lengths of stay and higher rates of deep vein thrombosis (4.89% vs. 0.44%, P = 0.02) and ventilator-associated pneumonia (4% vs. 0%, P = 0.02). Patients did not otherwise differ in mortality rate, other hospital complications, and discharge disposition. CONCLUSIONS: Octogenarians undergoing surgery for CCS experience longer length of stay and complications consistent with prolonged hospitalization but otherwise have similar mortality, hospital complications, and discharge disposition compared to non-surgical treatment. Given the relative lack of short-term drawbacks, surgery should be considered first-line management when the long-term benefits are substantive.

Racial Disparities in Time to Decompression in Central Cord Syndrome: A National Trauma Database Analysis.

OBJECTIVE: Cervical cord syndrome (CCS) is the most common type of incomplete spinal cord injury. Prompt surgical decompression within 24 hours increases neurologic function and rates of home discharge. Racial disparities exist in spinal cord injury, with Black patients experiencing longer lengths of stay and higher rates of complications than in White patients. This study aims to investigate potential racial disparities in time to surgical decompression in patients with CCS. METHODS: The National Trauma Data Bank (NTDB) was queried from 2017 to 2019 for patients who underwent surgery for CCS. The primary outcome was time from hospital admission to surgery. Student's t-test and Pearson's chi-squared test were used to evaluate differences in categorical and continuous variables, respectively. An uncensored Cox proportional hazards regression model was developed to assess the effect of race on surgical timing while adjusting for potential confounders. RESULTS: 1,076 patients with CCS resulting in cervical spinal cord surgery were included in the analysis. Regression analysis results showed that Black patients (HR=0.85, P = 0.03), female patients (HR=0.81, P < 0.01), and patients treated at community hospitals (HR=0.82, P = 0.01) were less likely to receive early surgery. CONCLUSIONS: Though the advantages of early surgical decompression in the setting of CCS have been detailed in medical literature, Black, and female patients experience lower rates of prompt surgery following hospital admission and higher rates of adverse outcomes. This disproportionately increased time to intervention exemplifies demographic disparities in the timely provision of treatment to patients with spinal cord injuries.
