Rural trauma education emphasizes that radiologic imaging should be discouraged if it delays transfer to definitive care. With increased capacity for image sharing, however, radiography obtained at referring hospitals (RH) could help providers at trauma centers (TC) prepare for patients with traumatic brain injury. We evaluated whether a head CT prior to transfer accelerated time to neurosurgical intervention at the TC. The study was conducted at a combined adult Level I and pediatric Level II TC with a catchment area that includes rural hospitals within a 150 mile radius. The trauma registry was used to identify patients with traumatic brain injury who went to surgery for a neurosurgical procedure immediately after arrival at the TC. All patients were transferred in from a RH. Differences between groups were assessed using analysis of variance and chi-square. Fifty-six patients met study criteria during the study period (2010-2015). The majority (86%) of patients received head CT imaging at the RH, including a significant percentage of patients (18%) who presented with GCS ≤8. There was no statistically significant decrease in time to surgery when patients received imaging at the RH. CTimaging was associated with a delay in transfer that exceeded 90 minutes. Findings demonstrate that imaging at the RH delayed transfer to definitive care and did not improve time to neurosurgical intervention at the TC. Transfer to the TC should not be obstructed by imaging, especially for patients with severe TBI.

Patients with severe traumatic brain injury (TBI) are at an increased risk of venous thromboembolism (VTE). Because of concerns of worsening intracranial hemorrhage, clinicians are hesitant to start VTE chemoprophylaxis in this population. We hypothesized that ACS Level I trauma centers would be more aggressive with VTE chemoprophylaxis in adults with severe TBI than Level II centers. We also predicted that Level I centers would have a lower risk of VTE. We queried the Trauma Quality Improvement Program (2010–2016) database for patients with Abbreviated Injury Scale scores of 4 and 5 of the head and compared them based on treating the hospital trauma level. Of 204,895 patients with severe TBI, 143,818 (70.2%) were treated at Level I centers and 61,077 (29.8%) at Level II centers. The Level I cohort had a higher rate of VTE chemoprophylaxis use (43.2% vs 23.3%, P < 0.001) and a shorter median time to chemoprophylaxis (61.9 vs 85.9 hours, P < 0.001). Although Level I trauma centers started VTE chemoprophylaxis more often and earlier than Level II centers, there was no difference in the risk of VTE ( P = 0.414) after controlling for covariates. Future prospective studies are warranted to evaluate the timing, safety, and efficacy of early VTE chemoprophylaxis in severe TBI patients.

ABSTRACTBACKGROUNDTraumatic brain injury (TBI) carries a devastatingly high rate of morbidity and mortality.OBJECTIVETo assess whether patients undergoing craniotomy/craniectomy for severe TBI fare better at level I than level II trauma centers in a mature trauma system.METHODSThe data were extracted from the Pennsylvania Trauma Outcome Study database. Inclusion criteria were patients &gt; 18 yr with severe TBI (Glasgow Coma Scale [GCS] score less than 9) undergoing craniotomy or craniectomy in the state of Pennsylvania from January 1, 2002 through September 30, 2017.RESULTSOf 3980 patients, 2568 (64.5%) were treated at level I trauma centers and 1412 (35.5%) at level II centers. Baseline characteristics were similar between the 2 groups except for significantly worse GCS scores at admission in level I centers (P = .002). The rate of in-hospital mortality was 37.6% in level I centers vs 40.4% in level II centers (P = .08). Mean Functional Independence Measure (FIM) scores at discharge were significantly higher in level I (10.9 ± 5.5) than level II centers (9.8 ± 5.3; P &lt; .005). In multivariate analysis, treatment at level II trauma centers was significantly associated with in-hospital mortality (odds ratio, 1.2; 95% confidence interval, 1.03-1.37; P = .01) and worse FIM scores (odds ratio, 1.4; 95% confidence interval, 1.1-1.7; P = .001). Mean hospital and ICU length of stay were significantly longer in level I centers (P &lt; .005).CONCLUSIONThis study showed superior functional outcomes and lower mortality rates in patients undergoing a neurosurgical procedure for severe TBI in level I trauma centers.

Abstract Objective Studies on Performance Validity Tests (PVTs) for tele-neuropsychology (TeleNP) are sparse. Verbal PVTs appear to better translate to TeleNP, so the primary objective of this study was to provide initial data on two well-established, verbal PVTs administered via TeleNP for research participants with traumatic brain injury (TBI). Methods This secondary analysis of the Veterans Affairs TBI Model Systems data included 53 participants enrolled in a PVT module study (3/01/2020–09/20/2020) with documented moderate-to-severe TBI per Glasgow Coma Score (M = 6.5, SD = 4.4), posttraumatic amnesia duration (M = 42.7 days, SD = 47.1), and/or time to follow commands (M = 10.5 days, SD = 16.3). Participants completed two PVTs—Reliable Digit Span (RDS) and the 21-Item Test (21-IT)—alongside telephone-based cognitive assessment 1–7 years after TBI. Descriptive analyses were performed to compare PVT performances to previously established cut scores. Chi square analyses were employed to examine 21-IT and RDS as dichotomous outcomes (pass/fail) at selected cutoffs. Results RDS ranged from 5 to 16 (M = 10.5, SD = 2.4). 21-IT ranged from 7 to 21 (M = 16.4, SD = 3.1). For RDS, 9.8% were invalid with a cutscore of ≤7 and 19.6% using a cutscore of ≤8. For the 21-IT, 7.8% were in invalid using a cutscore of ≤11, and 13.7% using a cutscore of ≤12. Conclusion(s) Using previously established cut scores, telephone-administered RDS and 21-IT resulted in relatively low rates of invalid performance among individuals with moderate-to-severe TBI. These findings provide preliminary support for the RDS and 21-IT in TeleNP.

Object More than 1.5 million Americans suffer a traumatic brain injury (TBI) each year. Seventy-five percent of these patients have a mild TBI, with Glasgow Coma Scale (GCS) Score 13–15. At the authors' institution, the usual practice has been to admit those patients with an associated intracranial hemorrhage (ICH) to an ICU and to obtain repeat head CT scans 12–24 hours after admission. The purpose of this study was to determine if there exists a subpopulation of mild TBI patients with an abnormal head CT scan that requires neither repeat brain imaging nor admission to an ICU. This group of patients was further classified based on initial clinical factors and imaging characteristics. Methods A retrospective review of all patients admitted to a Level I trauma center from January 2007 through December 2008 was performed using the hospital Trauma Registry Database, medical records, and imaging data. The inclusion criteria were as follows: 1) an admission GCS score ≥ 13; 2) an isolated head injury with no other injury requiring ICU admission; 3) an initial head CT scan positive for ICH; and 4) an initial management plan that was nonoperative. Collected data included age, etiology, initial GCS score, time of injury, duration of ICU stay, duration of hospital stay, and anticoagulation status. Primary outcomes measured were the occurrence of neurological or medical decline and the need for neurosurgical intervention. Imaging data were analyzed and classified based on the predominant blood distribution found on admission imaging. Data were further categorized based on the Marshall CT classification, Rotterdam score, and volume of intraparenchymal hemorrhage (IPH). Progression was defined as an increase in the Marshall classification, an increase in the Rotterdam score, or a 30% increase in IPH volume. Results Three hundred twenty-one of 1101 reviewed cases met inclusion criteria for the study. Only 4 patients (1%) suffered a neurological decline and 4 (1%) required nonemergent neurosurgical intervention. There was a medical decline in 18 of the patients (6%) as a result of a combination of events such as respiratory distress, myocardial infarction, and sepsis. Both patient age and the transfusion of blood products were significant predictors of medical decline. Overall patient mortality was 1%. Based on imaging data, the rate of injury progression was 6%. The only type of ICH found to have a significant rate of progression (53%) was a subfrontal/temporal intraparenchymal contusion. Other variables found to be significant predictors of progression on head CT scans were the use of anticoagulation, an age over 65 years, and a volume of ICH > 10 ml. Conclusions Most patients with mild TBI have a good outcome without the necessity of neurosurgical intervention. Mild TBI patients with a convexity SAH, small convexity contusion, small IPH (≤ 10 ml), and/or small subdural hematoma do not require admission to an ICU or repeat imaging in the absence of a neurological decline.

Severe traumatic brain injury (TBI) is associated with increased risk for early clinical and sub-clinical seizures. The use of continuous electroencephalography (cEEG) monitoring after TBI allows for identification and treatment of seizures that may otherwise occur undetected. Benefits of “routine” cEEG after TBI remain controversial. We examined the rate of subclinical seizures identified by cEEG in TBI patients admitted to a Level I trauma center. We analyzed a cohort of trauma patients with moderate to severe TBI (head Abbreviated Injury Score ≥3) who received cEEG within seven days of admission between October 2011 and May 2015. Demographics, clinical data, injury severity, and costs were recorded. Clinical characteristics were compared between those with and without seizures as identified by cEEG. A total of 106 TBI patients with moderate to severe TBI received a cEEG during the study period. Most were male (74%) with a mean age of 55 years. Subclinical seizures were identified by cEEG in only 3.8 per cent of patients. Ninety-three per cent were on antiseizure prophylaxis at the time of cEEG. Patients who had subclinical seizures were significantly older than their counterparts (80 vs 54 years, P = 0.03) with a higher mean head Abbreviated Injury Score (5.0 vs 4.0, P = 0.01). Mortality and intensive care unit stay were similar in both groups. Of all TBI patients who were monitored with cEEG, seizures were identified in only 3.8 per cent. Seizures were more likely to occur in older patients with severe head injury. Given the high cost of routine cEEG and the low incidence of subclinical seizures, we recommend cEEG monitoring only when clinically indicated.

Neuroimaging Techniques

The purpose of this article is to review conventional and advanced neuroimaging techniques performed in the setting of traumatic brain injury (TBI). The primary goal for the treatment of patients with suspected TBI is to prevent secondary injury. In the setting of a moderate to severe TBI, the most appropriate initial neuroimaging examination is a noncontrast head computed tomography (CT), which can reveal life-threatening injuries and direct emergent neurosurgical intervention. We will focus much of the article on advanced neuroimaging techniques including perfusion imaging and diffusion tensor imaging and discuss their potentials and challenges. We believe that advanced neuroimaging techniques may improve the accuracy of diagnosis of TBI and improve management of TBI.

Neurosurgical Intervention

Trauma patients presenting with a Glasgow Coma Scale (GCS) score of 14–15 are considered to have mild traumatic brain injury (TBI) with overall good neurologic outcomes. Current practice consists of initial stabilization, followed by a head CT, and neurosurgical consultation. Aside from serial neurologic examinations, patients with a GCS of 15 rarely require neurosurgical intervention. In this study, we examined the added value of neurosurgical consultation in the care of patients after TBI with a GCS of 15. We retrospectively reviewed the medical records of patients presenting after blunt trauma with an abnormal head CT and GCS of 15 between January 2004 and January 2005. Patients with a normal head CT and <48 hours hospital stay were excluded. Data included demographics, mechanisms of injury, Injury Severity Score, the radiologists’ dictated interpretations of the head CT, and neurosurgical interventions. Fifty-six patients met the inclusion criteria. The mean age was 41 ± 2.3 years, and the mean Injury Severity Scores was 10.2 ± 0.6. Mechanisms of injury included 64 per cent motor vehicle crash, 16 per cent motorcycle crash, 13 per cent fall, and 7 per cent all-terrain vehicle crash. The initial CT scans showed 43 per cent parenchymal contusions, 38 per cent subarachnoid hemorrhage, 14 per cent subdural hematomas, and 5 per cent epidural hematomas. All patients received a routine follow-up head CT, and 16 per cent showed changes (five improved and four were worse compared with initial CT scans). None of these patients received a neurosurgical intervention, and two were transferred to a rehabilitation service. In this era of limited resources, trauma patients who present with a GCS score of 15 after mild TBI can be safely managed without neurosurgical consultation, even in the presence of an abnormal head CT scan.

Traumatic brain injury (TBI) is a major cause of death and disability in children in both developed and developing nations. Children and adolescents suffer from TBI at a higher rate than the general population; however, research in this population lags behind research in adults. This may be due, in part, to the smaller number of investigators engaged in research with this population and may also be related to changes in safety laws and clinical practice that have altered length of hospital stays, treatment, and access to this population. Specific developmental issues also warrant attention in studies of children, and the ever-changing context of childhood and adolescence may require larger sample sizes than are commonly available to adequately address remaining questions related to TBI. The ENIGMA (Enhancing NeuroImaging Genetics through Meta-Analysis) Pediatric Moderate-Severe TBI (msTBI) group aims to advance research in this area through global collaborative meta-analysis. In this paper we discuss important challenges in pediatric TBI research and opportunities that we believe the ENIGMA Pediatric msTBI group can provide to address them. We conclude with recommendations for future research in this field of study.
