Objective: Decompressive craniectomy is recommended to reduce mortality in severe traumatic brain injury (TBI). Disparities exist in TBI treatment outcomes; however, data on disparities pertaining to decompressive craniectomy utilization is lacking. We investigated these disparities, focusing on race, insurance, sex, and age., Methods: Hospitalizations (2004-2014) were retrospectively extracted from the Nationwide Inpatient Sample. The criteria included are as follows: age ≥18 years and indicators of severe TBI diagnosis. Poor outcomes were defined as discharge to institutional care and death. Multivariable logistic regression models were used to assess the effects of race, insurance, age, and sex, on craniectomy utilization and outcomes., Results: Of 349,164 hospitalized patients, 6.8% (n = 23,743) underwent craniectomy. White (odds ratio [OR] = 0.50, 95% confidence interval [CI] = 0.44-0.57; P < 0.001) and Black (OR = 0.45, 95% CI = 0.32-0.64; P = 0.003) Medicare beneficiaries were less likely to undergo craniectomy. Medicare (P < 0.0001) and Medicaid beneficiaries (P < 0.0001) of all race categories had poorer outcomes than privately insured White patients. Black (OR = 1.2, 95% CI = 1.08-2.34; P = 0.001) patients with private insurance and Black (OR = 1.39, 95% CI = 1.22-1.58; P < 0.0001) Medicaid beneficiaries had poorer outcomes than privately insured White patients (P < 0.0001). Older patients (OR = 0.74, 95%, CI = 0.71-0.76; P < 0.001) were less likely to undergo craniectomy and were more likely to have poorer outcomes. Females (OR = 0.82, 95% CI = 0.76-0.88; P < 0.001) were less likely to undergo craniectomy., Conclusions: There are disparities in race, insurance status, sex, and age in craniectomy utilization and outcome. This data highlights the necessity to appropriately address these disparities, especially race and sex, and actively incorporate these factors in clinical trial design and enrollment., (Copyright © 2022 Elsevier Inc.

Objective: Traumatic brain injury (TBI) is a risk factor for venous thromboembolism (VTE). The risk of VTE after decompressive craniectomy (DC) and its effects on the outcomes are unknown. We assessed the incidence of VTE, associated risk factors, and effects on the outcomes., Methods: Using the National Inpatient Sample database, the hospitalizations of patients aged ≥18 years with a severe TBI diagnosis from 2004 to 2014 were extracted. The outcome was discharge status without mortality. Multivariable logistic and linear regressions were used., Results: Of the 349,165 TBI hospitalizations, 23,813 (6.82%) had undergone DC and 14,175 (4.06%) had developed VTE. The VTE incidence was higher after DC compared with no DC (6.14% vs. 3.91%; P < 0.0001). DC (odds ratio [OR], 1.29; P < 0.005) was an independent predictor for the development of VTE. Age (OR, 1.26; P < 0.005), chronic lung disease (OR, 1.58; P < 0.05), electrolyte imbalance (OR, 1.43; P < 0.05), liver disease (OR, 0.10; P < 0.05), urinary tract infection (OR, 1.56; P < 0.05), pneumonia (OR, 2.03; P < 0.0001), and sepsis (OR, 1.57; P < 0.05) were significantly associated with the development of VTE. Obesity (OR, 2.09; P > 0.05) and spine injury (OR, 2.03; P > 0.05) showed a trend toward significance. VTE was associated with worse discharge outcomes (OR, 1.40; P < 0.05), longer lengths of stay (OR, 1.01; P < 0.00001), and higher costs (P < 0.0001)., Conclusions: Our study showed an independent association between DC and an increased risk of VTE for patients with severe TBI. The development of VTE after DC increased the proportion of poor outcomes, prolonged the length of stay, and increased the hospitalization costs. Older patients with obesity, an electrolyte imbalance, chronic lung disease, spine injury, and infections were at a greater risk of VTE after DC. These risk factors could help in considering VTE prophylaxis for these patients., (Copyright © 2022 Elsevier Inc. All rights reserved.)

Objective: Cervical spine injury screening is common practice for traumatic brain injury (TBI) patients. However, risk factors for concomitant thoracolumbar trauma remain unknown. We characterized epidemiology and clinical risk for concomitant thoracolumbar trauma in TBI., Methods: We conducted a multi-center, retrospective cohort analysis of TBI patients in the National Trauma Data Bank from 2011-2014 using multivariable logistic regression., Results: Out of 768,718 TBIs, 46,654 (6.1%) and 42,810 (5.6%) patients were diagnosed with thoracic and lumbar spine fractures, respectively. Only 11% of thoracic and 7% of lumbar spine fracture patients had an accompanying spinal cord injury at any level. The most common mechanism of injury was motor vehicle accident (67% of thoracic and 71% and lumbar fractures). Predictors for both thoracic and lumbar fractures included moderate (thoracic: OR 1.26, 95%CI 1.21-1.31; lumbar: OR 1.13, 95%CI 1.08-1.18) and severe Glasgow Coma Scale (GCS) score (OR 1.71, 95%CI 1.67-1.75; OR 1.17, 95%CI 1.13-1.20) compared to mild; epidural hematoma (OR 1.36, 95%CI 1.28-1.44; OR 1.1, 95%CI 1.04-1.19); lower extremity injury (OR 1.38, 95%CI 1.35-1.41; OR 2.50, 95%CI 2.45-2.55); upper extremity injury (OR 2.19, 95%CI 2.14-2.23; OR 1.15, 95%CI 1.13-1.18); smoking (OR 1.09, 95%CI 1.06-1.12; OR 1.12, 95%CI 1.09-1.15); and obesity (OR 1.39, 95%CI 1.34-1.45; OR 1.29, 95%CI 1.24-1.35). Thoracic injuries (OR 4.45; 95% CI 4.35-4.55) predicted lumbar fractures, while abdominal injuries (OR 2.02; 95% CI 1.97-2.07) predicted thoracic fractures., Conclusions: We identified GCS, smoking, upper and lower extremity injuries, and obesity as common risk factors for thoracic and lumbar spinal fractures in TBI., Competing Interests: Declaration of Competing Interest The authors declare that the article content was composed in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021.
