ABSTRACT
PURPOSE: The objectives of this study were to analyse the clinical value of protein S100b (S100b) in association with clinical findings and anticoagulation therapy in predicting traumatic intracranial haemorrhage (tICH) and unfavourable outcomes in elderly individuals with low-energy falls (LEF). METHODS: We conducted a retrospective study in the emergency department (ED) of the LMU University Hospital, Munich by consecutively including all patients aged ≥ 65 years presenting to the ED following a LEF between September 2014 and December 2016 and receiving an emergency cranial computed tomography (cCT) examination. Primary endpoint was the prevalence of tICH. Multivariate logistic regression models and receiver operating characteristics were used to measure the association between clinical findings, anticoagulation therapy and S100b and tICH. RESULTS: We included 2687 patients, median age was 81 years (60.4% women). Prevalence of tICH was 6.7% (180/2687) and in-hospital mortality was 6.1% (11/180). Skull fractures were highly associated with tICH (odds ratio OR 46.3; 95% confidence interval CI 19.3-123.8, p < 0.001). Neither anticoagulation therapy nor S100b values were significantly associated with tICH (OR 1.14; 95% CI 0.71-1.86; OR 1.08; 95% CI 0.90-1.25, respectively). Sensitivity of S100b (cut-off: 0.1 ng/ml) was 91.6% (CI 95% 85.1-95.9), specificity was 17.8% (CI 95% 16-19.6), and the area under the curve value was 0.59 (95% CI 0.54 - 0.64) for predicting tICH. CONCLUSION: In conclusion, under real ED conditions, neither clinical findings nor protein S100b concentrations or presence of anticoagulation therapy was sufficient to decide with certainty whether a cCT scan can be bypassed in elderly patients with LEF. Further prospective validation is required.

PURPOSE: The purpose of this study was to assess the performance of a decision-tree for head-CT indication in elderly patients presenting minor traumatic injuries MATERIALS AND METHODS: A single-centre retrospective study was performed and analyses were based on emergency CT scans of all patients aged 65 and over who experienced minor head trauma due to falls. The primary judgement criteria was the diagnosis of a traumatic intracranial haemorrhagic lesion (tICH) depicted on the CT scan. Focal neurological deficit and history of tICH on a previous CT scan were used to create the decision-tree. RESULTS: A total of 1001 patients were included. Ninety-five (9.5%) had tICH on the CT scan. Of these patients, 42 (46.1%) had an abnormal Glasgow Coma Scale, 30 (31.6%) a focal neurological deficit and 13 (13.7%) a history of tICH on a previous CT scan. The presence of at least one of these 3 risk factors was associated with the occurrence of tICH (p <0.001). The decision-tree developed from these risk factors allowed the appropriate classification of 63 of 95 patients (66.3%) with tICH. Undetected haemorrhagic lesions in patients with no clinical severity criteria evolved favourably. The decision-tree correctly identified 97% of patients without any tICH on the CT. CONCLUSION: Systematic head CT for elderly patients presenting minor head trauma could be irrelevant. A decision-tree based on objective clinical severity criteria for the indication of head CT could detect the majority of tICH requiring surgical intervention. Prospective randomized studies are mandatory to confirm these hypotheses.

OBJECTIVE: Limited evidence exists characterizing the incidence, risk factors, and clinical associations of cerebral vasospasm following traumatic intracranial hemorrhage (tICH) on a large scale. Therefore, the authors sought to use data from a national inpatient registry to investigate these aspects of posttraumatic vasospasm (PTV) to further elucidate potential causes of neurological morbidity and mortality subsequent to the initial insult. METHODS: Weighted discharge data from the National (Nationwide) Inpatient Sample from 2015 to 2018 were queried to identify patients with tICH who underwent diagnostic angiography in the same admission and, subsequently, those who developed angiographically confirmed cerebral vasospasm. Multivariable logistic regression analysis was performed to identify significant associations between clinical covariates and the development of vasospasm, and a tICH vasospasm predictive model (tICH-VPM) was generated based on the effect sizes of these parameters. RESULTS: Among 5880 identified patients with tICH, 375 developed PTV corresponding to an incidence of 6.4%. Multivariable adjusted modeling determined that the following clinical covariates were independently associated with the development of PTV, among others: age (adjusted odds ratio [aOR] 0.98, 95% CI 0.97-0.99; p < 0.001), admission Glasgow Coma Scale score < 9 (aOR 1.80, 95% CI 1.12-2.90; p = 0.015), intraventricular hemorrhage (aOR 6.27, 95% CI 3.49-11.26; p < 0.001), tobacco smoking (aOR 1.36, 95% CI 1.02-1.80; p = 0.035), cocaine use (aOR 3.62, 95% CI 1.97-6.63; p < 0.001), fever (aOR 2.09, 95% CI 1.34-3.27; p = 0.001), and hypokalemia (aOR 1.62, 95% CI 1.26-2.08; p < 0.001). The tICH-VPM achieved moderately high discrimination, with an area under the curve of 0.75 (sensitivity = 0.61 and specificity = 0.81). Development of vasospasm was independently associated with a lower likelihood of routine discharge (aOR 0.60, 95% CI 0.45-0.78; p < 0.001) and an extended hospital length of stay (aOR 3.53, 95% CI 2.78-4.48; p < 0.001), but not with mortality. CONCLUSIONS: This population-based analysis of vasospasm in tICH has identified common clinical risk factors for its development, and has established an independent association between the development of vasospasm and poorer neurological outcomes.

INTRODUCTION: Patients with traumatic intracranial hemorrhage (tICH) often require intensive care unit (ICU) admission until bleeding stability is demonstrated through interval head computed tomography (HCT). The brain injury guidelines (BIG) suggest a minimum 24-h ICU admission for severe patients (BIG 3) regardless of repeat CT stability. We sought to evaluate the rate of tICH expansion after an initial stable interval scan was obtained. METHODS: A single-center retrospective cohort study at a level 1 trauma center was performed. All adult patients with tICH evaluated using BIG criteria were included. The primary endpoint was incidence of tICH expansion after initial stability on interval HCT performed at approximately 6 h. Secondary endpoints included time to tICH stability, frequency of neurosurgical intervention, and time to surgical intervention. RESULTS: A total of 1517 patients met inclusion criteria. Of the 1121 patients with repeat imaging, 288 (25.7%) experienced progression with 94.4% detected on the initial 6-h interval scan. Of all patients with initially stable repeat imaging (n = 833), progression occurred in 16 (1.9%) patients. Of these patients, 5 required neurosurgical intervention, 4 received increased monitoring, 2 transitioned to comfort measures and 5 had no change in management. The median time from initial scan to expansion in these patients was 42.2 h. Median time to surgical intervention after post-stability expansion was 102 h. CONCLUSION: Patients who demonstrate bleeding stability on first interval HCT after tICH rarely experience expansion. Consideration should be given to discharging patients from the ICU when initial interval HCT shows no progression.

The number of patients with traumatic intracranial hemorrhage (tICH) that are taking antithrombotics (ATs), antiplatelets (APs) and/or anticoagulants (ACs), has increased, but the influence of it for outcome remains unclear. This study aimed to evaluate an influence of AT for tICH. We retrospectively reviewed all patients with tICH treated between 2012 and 2019, and analyzed demographics, neurological status, clinical course, radiological findings, and outcome data. A total of 393 patients with tICH were included; 117 were on AT therapy (group A) and 276 were not (group B). Fifty-one (43.6%) and 159 (57.6%) patients in groups A and B, respectively, exhibited mRS of 0-2 at discharge (p = 0.0113). Mortality at 30 days was significantly higher in group A than in group B (25.6% vs 16.3%, p = 0.0356). Multivariate analysis revealed that higher age (OR 32.7, p < 0.0001), female gender (OR 0.56, p = 0.0285), pre-injury vitamin K antagonist (VKA; OR 0.42, p = 0.0297), and hematoma enlargement (OR 0.27, p < 0.0001) were associated with unfavorable outcome. AP and direct oral anticoagulant were not. Hematoma enlargement was significantly higher in AC-users than in non-users. Pre-injury VKA was at high risk of poor prognosis for patients with tICH. To improve outcomes, the management of VKA seems to be important.

BACKGROUND: Emergency department visits due to head injury in the United States have increased significantly over the past decade, and parallel the increasing use of direct oral anticoagulants (DOACs). OBJECTIVE: We investigated the incidence of delayed intracranial hemorrhage (DICH) in patients with head injury who were taking DOACs. METHODS: We conducted a single-center retrospective study at a level II trauma center. All patients with head injury and using DOACs with an initial negative head computed tomography (HCT) scan from March 1, 2014 to December 31, 2017 were included. DICH was identified as a positive finding on repeat HCT performed within 24 h. Each case of DICH underwent blinded review by two additional neuroradiologists. Demographic data were collected; independent t-tests were used to compare group means and linear regression for variable correlations. RESULTS: Two hundred and eighty-seven patients with mean age of 80 years (interquartile range 14 years) met inclusion criteria. Repeat HCT was performed in 224 study participants (78%). Five (1.7%) resulted in DICH, three of which might have been present on initial HCT, with an incidence rate ranging from 0.7% to 1.7%. Only two initial HCTs were read as negative by all three neuroradiologists; 60% disagreed on the initial read. Independent t-test procedures showed an association between DICH and higher Injury Severity Score (ISS). CONCLUSIONS: We found a DICH incidence rate of 0.7-1.7%. ISS was statistically significant between the two groups. It is possible that in patients with a subjective estimation of low injury severity, a low mechanism of injury and reasonable outpatient follow-up, patients can be discharged home with standard head injury precautions and no repeat HCT, but further prospective studies are needed.

OBJECTIVE: To examine the occurrence of traumatic intracranial hemorrhage (tICH) and outcome in patients with minor head injury and assess the probable risk factors. METHODS: Patients with minor head injury who visited our hospital from January 2015 to July 2017 were registered consecutively, and enrolled patients were aged ≥18 years, visited within 24 hours of the injury, and had a Glasgow Coma Scale score of 15 at outpatient clinic or before the injury. RESULTS: Of the 1122 enrolled patients, 55 (4.9%) had tICH. An antiplatelet agent was administered in 114 patients, an anticoagulant agent was administered in 49 patients, and none of them were administered in 948 patients. A multivariate analysis of tICH identified it as a risk factor, showing significant difference between antiplatelet medication (P = 0.0312), fall from stairs (P = 0.0057), traffic accident (P = 0.0117), neurologic symptoms (P = 0.0091), and modified Rankin Scale (mRS) score before trauma (P < 0.0001). We also analyzed association of enlargement of tICH with different parameters and only anticoagulant medication indicated an increased risk (P = 0.0005). Thirty patients (2.6%) were dependent or died at discharge (mRS 3-6). The mRS score before trauma (P < 0.0001), tICH (P < 0.0001), spinal injury (P < 0.0001), and enlargement of intracranial hemorrhage (P = 0.0008) indicated an increased probability of morbidity (mRS 3-6) in multivariate analysis. CONCLUSIONS: Antiplatelet and anticoagulant medications were risk factor for tICH and enlargement of tICH in patients with minor head injury, respectively. A pretrauma condition of disability/dependence is an important risk factor for tICH and outcome.

OBJECTIVES: The primary objective of this study was to determine the incidence of clinically significant traumatic intracranial hemorrhage (T-ICH) following minor head trauma in older adults. Secondary objective was to investigate the impact of anticoagulant and antiplatelet therapies on T-ICH incidence. METHODS: This retrospective cohort study extracted data from electronic patient records. The cohort consisted of patients presenting after a fall and/or head injury and presented to one of five ED between 1st March 2010 and 31st July 2017. Inclusion criteria were age ≥ 65 years old and a minor head trauma defined as an impact to the head without fulfilling criteria for traumatic brain injury. RESULTS: From the 1,000 electronic medical records evaluated, 311 cases were included. The mean age was 80.1 (SD 7.9) years. One hundred and eighty-nine (189) patients (60.8%) were on an anticoagulant (n = 69), antiplatelet (n = 130) or both (n = 16). Twenty patients (6.4%) developed a clinically significant T-ICH. Anticoagulation and/or antiplatelets therapies were not associated with an increased risk of clinically significant T-ICH in this cohort (Odds ratio (OR) 2.7, 95% CI 0.9-8.3). CONCLUSIONS: In this cohort of older adults presenting to the ED following minor head trauma, the incidence of clinically significant T-ICH was 6.4%.

BACKGROUND/OBJECTIVES: To determine the prevalence and severity of traumatic intracranial hemorrhage (tICH) in a large cohort of older adults presenting with low-energy falls and the association with anticoagulation or antiplatelet medication. DESIGN: Bicentric retrospective cohort analysis. SETTING: Two level 1 trauma centers in Switzerland and Germany. PARTICIPANTS: Consecutive sample of older adults (aged ≥65 y) presenting to the emergency department (ED) over a 1-year period with low-energy falls who received cranial computed tomography (cCT) within 48 hours of ED presentation. MEASUREMENTS: The prevalence and severity of tICHs was assessed and the outcomes (in-hospital mortality, admission to intensive care unit [ICU], or neurosurgical intervention) were specified. We used multivariate regression models to measure the association between anticoagulation/antiplatelet therapy and the risk for tICH after adjustment for known predictors. RESULTS: The overall prevalence for tICH detected by cCT was 176 of 2567 (6.9%). Neurosurgical intervention was performed in 15 of 176 (8.5%) patients with tICH, 28 of 176 (15.9%) patients were admitted to the ICU, and 14 of 176 (8.0%) died in the hospital. CT-detected skull fracture and signs of injury above the clavicles were the strongest predictors for the presence of tICH (odds ratio [OR] = 4.28; 95% confidence interval [CI] = 2.79-6.51; OR = 1.88; 95% CI = 1.3-2.73, respectively). Among 2567 included patients, 1424 (55%) were on anticoagulation/antiplatelet therapy. Multivariate regression models showed no differences for the risk of tICH (OR = 1.05; 95% CI = .76-1.47; P = .76) or association with the head-specific Injury Severity Scale (incident rate ratio = 1.08; 95% CI = .97-1.19; P = .15) with or without anticoagulation/antiplatelet therapy. CONCLUSION: Medication with anticoagulants or antiplatelet agents was not associated with higher prevalence and severity of tICH in older patients with low-energy falls undergoing cCT examination. In addition to cCT-detected skull fractures, visible injuries above the clavicles were the strongest clinical predictors for tICH. Our findings merit prospective validation.

OBJECTIVES: Emergency department (ED) visits among older adults are frequently instigated by a fall at home. Some of these patients develop intracranial bleeding. The aim of this study was to identify the incidence of intracranial bleeding and the associated clinical features in older adults who present to the ED after falling. DESIGN: Prospective cohort study. SETTING: Three Canadian EDs. PARTICIPANTS: A total of 2 176 patients age 65 years or older who presented to the ED with a fall were assessed, and 1753 were included. Inclusion criteria were a fall on level ground, off a bed, chair, or toilet, or from one or two steps within 48 hours. MEASUREMENTS: Emergency physicians recorded predefined clinical findings on initial assessment. The primary outcome was intracranial bleeding, diagnosed either by computed tomography at the index visit or within 42 days. Associations between baseline clinical findings and the presence of intracranial bleeding were assessed with multivariable logistic regression. RESULTS: A total of 1753 patients (median age = 82 y) were enrolled, of whom 39% were male, 35% were on antiplatelet therapy, and 25% were on an anticoagulant. The incidence of intracranial bleeding was 5.0% (95% confidence interval [CI] = 4.1-6.1). Overall, 76 patients were diagnosed at the index ED visit, and 12 were diagnosed during follow-up. Multivariable regression identified four clinical variables that were independently associated with intracranial bleeding: new abnormalities on neurologic examination (odds ratio [OR] = 4.4; 95% CI = 2.4-8.1), bruise or laceration on the head (OR = 4.3; 95% CI = 2.7-7.0), chronic kidney disease (OR = 2.4; 95% CI = 1.3-4.6), and reduced Glasgow Coma Scale from normal (OR = 1.9; 95% CI = 1.0-3.4). CONCLUSION: The incidence of intracranial bleeding in our study was 5.0%. We found significant associations between intracranial bleeding and four simple clinical variables. We did not find significant associations between intracranial bleeding and antiplatelet or anticoagulant use. J Am Geriatr Soc 68:970-976, 2020.

BACKGROUND: This study aims to analyze the incidence and outcomes of bicycle-related injuries in hospitalized patients in The Netherlands. METHODS: Bicycle accidents resulting in hospitalization in a level-I trauma center in The Netherlands between 2007 and 2017 were retrospectively identified. We subcategorized data of patients involved in a regular bicycle, race bike, off-road bike or e-bike accident. The primary outcomes were mortality rate and incidence of multitrauma. Secondary outcomes were differences between bicycle subcategories. Independent risk factors were identified using multivariable logistic regression. All variables with a p value < 0.20 in univariable analysis were entered in multivariable analysis. RESULTS: We identified 1986 patients. The mortality rate after emergency room admission was 5.7%, and 41.0% were multitraumas. A higher age, multitrauma and cerebral haemorrhages were independent risk factors for in hospital mortality. Independent risk factors found for multitrauma were a higher age, two-sided trauma, e-bike accidents and cerebral haemorrhage. CONCLUSION: Bicycle accidents resulting in hospitalization have a high mortality rate. Furthermore, a high incidence of multitrauma, fractures and cerebral haemorrhages were found. Considering the increasing incidence of bicycle accident victims needing hospital admission, new and more efficient prevention strategies are essential.

BACKGROUND: There is debate regarding routine repeat head computed tomography (CT) in blunt trauma patients on a pre-injury antithrombotic when the initial CT is negative for intracranial hemorrhage (ICH). DATA SOURCES: Retrospective chart review and systematic literature review with meta-analysis. CONCLUSIONS: In the chart review, 32.1% did not have a repeat head CT and 67.9% did. The delayed ICH incidence between those with and without a repeat head CT was similar (1.7% vs 0, pâ¯=â¯.3101). The current study was combined with the identified 24 studies. Delayed ICH with or without routine repeat CT was similar between antiplatelet and anticoagulant categories (1.4% vs. 1.3%, pâ¯=â¯.5322). Delayed ICH was lower for patients without routine repeat CT compared to those with routine repeat CT (0.8% vs 1.7%, pâ¯=â¯.0008). For this patient population, repeat scans should be discretionary. Routine repeat CT may identify a larger proportion of minor delayed ICH.

Objective: To evaluate the accuracy of emergency medical services (EMS) provider judgment for traumatic intracranial hemorrhage (tICH) in older patients following head trauma in the field. We also compared EMS provider judgment with other sets of field triage criteria. Methods: This was a prospective observational cohort study conducted with five EMS agencies and 11 hospitals in Northern California. Patients 55 years and older who experienced blunt head trauma were transported by EMS between August 1, 2015 and September 30, 2016, and received an initial cranial computed tomography (CT) imaging, were eligible. EMS providers were asked, "What is your suspicion for the patient having intracranial hemorrhage (bleeding in the brain)?" Responses were recorded as ordinal categories (<1%, 1-5%, >5-10%, >10-50%, or >50%) and the incidences of tICH were recorded for each category. The accuracy of EMS provider judgment was compared to other sets of triage criteria, including current field triage criteria, current field triage criteria plus multivariate logistical regression risk factors, and actual transport. Results: Among the 673 patients enrolled, 319 (47.0%) were male and the median age was 75 years (interquartile range 64-85). Seventy-six (11.3%) patients had tICH on initial cranial CT imaging. The increase in EMS provider judgment correlated with an increase in the incidence of tICH. EMS provider judgment had a sensitivity of 77.6% (95% CI 67.1-85.5%) and a specificity of 41.5% (37.7-45.5%) when using a threshold of 1% or higher suspicion for tICH. Current field triage criteria (Steps 1-3) was poorly sensitive (26.3%, 95% CI 17.7-37.2%) in identifying tICH and current field trial criteria plus multivariate logistical regression risk factors was sensitive (97.4%, 95% CI 90.9-99.3%) but poorly specific (12.9%, 95% CI 10.4-15.8%). Actual transport was comparable to EMS provider judgment (sensitivity 71.1%, 95% CI 60.0-80.0%; specificity 35.3%, 95% CI 31.6-38.3%). Conclusions: As EMS provider judgment for tICH increased, the incidence for tICH also increased. EMS provider judgment, using a threshold of 1% or higher suspicion for tICH, was more accurate than current field triage criteria, with and without additional risk factors included.

BACKGROUND: Hospital admissions resulting from traumatic intracranial haemorrhages (TIH) in older people are increasing. There are concerns regarding an increased risk of a TIH in people taking oral anticoagulants (OAC) like phenprocoumon. AIMS: The aim of this study was to estimate the incremental risk of a TIH associated with OAC in older people. Furthermore, this study explored differences in risk according to functional status. METHODS: The study took data from a large German health insurance provider and combined hospital diagnoses with data regarding drug dispensing to estimate rates of a TIH in people with and without exposure to phenprocoumon. Analyses were stratified by sex and by severe functional impairment as disclosed by the long-term care insurance provider. RESULTS: Overall, exposure to OAC resulted in 2.7 times higher rates of TIH. People with severe functional impairment had a higher baseline risk of TIH than people without severe functional impairment. However, the incremental risk in those exposed to OAC was similar among people with and without severe functional impairment (standardised incidence rate difference 15.73 (95% CI 7.84; 23.61) and 12.10 (95% CI 9.63; 14.57) per 10,000 person-years, respectively). CONCLUSIONS: OAC increases the risk of TIH considerably. The incremental risk of TIH in those exposed to OAC is comparable between people with and without severe functional impairment. The presence of severe functional impairment per se should not exclude such patients from the potential benefits of OAC. For now, the prescription should be personalized based on individual fall risk factors and risk-taking behaviour.

OBJECTIVES: The aim of this study was to investigate the association between increased weight status (IWS), a weight for age/sex at greater than the 95th percentile, and fall-induced intracranial hemorrhage (ICH) in children aged 4 years or younger. METHODS: In 7072 children aged 4 years or younger with head injury who visited a tertiary care hospital emergency department in Korea from 2013 through 2015, the presence of fall-induced ICH was reviewed. The association between IWS and ICH was investigated by multivariable logistic regression. We retrospectively validated the Pediatric Emergency Care Applied Research Network rule alone and in combination with IWS for predicting ICH. RESULTS: Of 7072 children, 547 (7.7%) underwent computed tomography, of whom 451 (6.4%) were enrolled. Of these, 41 (9.1%; estimated event rate, 0.6%) had ICHs, and 26 (5.8%) had IWS. Increased weight status was more common in the children with ICH (P = 0.023). The association between IWS and ICH remained significant after adjustment (odds ratio, 5.24; 95% confidence interval [CI], 1.49-18.46; P = 0.010). The validation of the rule in combination with IWS showed no significant increases in a sensitivity (92.7% [95% CI, 80.1%-98.5%] to 95.7% [95% CI, 83.5%-99.4%]) and negative predictive value (98.2% [95% CI, 94.7%-99.4%] to 98.8% [95% CI, 95.4%-99.8%]). CONCLUSIONS: Increased weight status is associated with fall-induced ICH in children aged 4 years or younger. Information on weight status could be potentially helpful in predicting ICH in young children with fall-induced head injury.

BACKGROUND: Head trauma is a health problem that may be observed in all age groups, and it may cause significant losses in terms of health and economy. The purpose of our study is to evaluate the abnormal computerized brain tomography (CBT) prevalence and the rate of admission to brain surgery clinics in patients who applied to the Emergency Service Department for CBT due to minor head trauma. METHODS: In the present study, the patients who were admitted to Afyonkarahisar Health Sciences University, Faculty of Medicine Hospital, Emergency Service Department between January 1st, 2017, and December 31st, 2017, due to head trauma and in who CBT was performed were examined retrospectively. The electronic files, CBTs, and consultation notes of these patients were accessed in the information system of the hospital. RESULTS: A total of 43,389 patients who applied to the Emergency Service Department in 1 years' time (2017) were examined retrospectively. As a result of the examination, it was determined that a total of 2,515 (5.7%) patients received CBT. The reason for a total of 1,152 (45%) of these patients was traumatic injury. It was determined that 618 (53.6%) of the patients in who CBT was performed due to trauma were aged <18 years; 280 (24.3%) patients were aged <2 years; 179 (15.5%) patients had to consult with the Brain Surgery Clinic; and 94 (8.1%) were hospitalized. It was also determined that there were abnormal computed tomography (CT) findings in only 68 (5.9%) of the patients in who CBT was performed. CONCLUSION: The use of CBT indication criteria, which have been previously established and which reliability has been proven, in emergency trauma cases applying to the Emergency Service Department with minor head traumas may reduce the complication risk that may appear as a result of an unnecessary CBT and avoid complications that may occur in the long run due to CBT.

BACKGROUND: Traumatic brain injury (TBI) remains a life-threatening condition characterized by growing incidence worldwide, particularly in the aging population, in which the primary goal of treatment appears to be avoidance of chronic institutionalization. METHODS: To identify independent predictors of 30-day mortality or vegetative state in a geriatric population and calculate an intuitive scoring system, we screened 480 patients after TBI treated at a single department of neurosurgery over a 2-year period. We analyzed data of 214 consecutive patients aged ≥65 years, including demographics, medical history, cause and time of injury, neurologic state, radiologic reports, and laboratory results. A predictive model was developed using logistic regression modeling with a backward stepwise feature selection. RESULTS: The median Glasgow Coma Scale (GCS) score on admission was 14 (interquartile range, 12-15), whereas the 30-day mortality or vegetative state rate amounted to 23.4%. Starting with 20 predefined features, the final prediction model highlighted the importance of GCS motor score (odds ratio [OR], 0.17; 95% confidence interval [CI], 0.09-0.32); presence of comorbid cardiac, pulmonary, or renal dysfunction or malignancy (OR, 2.86; 9 5% CI, 1.08-7.61); platelets ≤100 × 109 cells/L (OR, 13.60; 95% CI, 3.33-55.49); and red blood cell distribution width coefficient of variation ≥14.5% (OR, 2.91; 95% CI, 1.09-7.78). The discovered coefficients were used for nomogram development. It was further simplified to facilitate clinical use. The proposed scoring system, Elderly Traumatic Brain Injury Score (eTBI Score), yielded similar performance metrics. CONCLUSIONS: The eTBI Score is the first scoring system designed specifically for older adults. It could constitute a framework for clinical decision-making and serve as an outcome predictor. Its capability to stratify risk provides reliable criteria for assessing efficacy of TBI management.

OBJECTIVES: To examine cerebral autoregulation in children with complex mild traumatic brain injury. DESIGN: Prospective observational convenience sample. SETTING: PICU at a level I trauma center. PATIENTS: Children with complex mild traumatic brain injury (trauma, admission Glasgow Coma Scale score 13-15 with either abnormal head CT, or history of loss of consciousness). INTERVENTIONS: Cerebral autoregulation was tested using transcranial Doppler ultrasound between admission day 1 and 8. MEASUREMENTS AND MAIN RESULTS: The primary outcome was prevalence of impaired cerebral autoregulation (autoregulation index < 0.4),determined using transcranial Doppler ultrasonography and tilt testing. Secondary outcomes examined factors associated with and evolution and extent of impairment. Cerebral autoregulation testing occurred in 31 children 10 years (SD, 5.2 yr), mostly male (59%) with isolated traumatic brain injury (91%), median admission Glasgow Coma Scale 15, Injury Severity Scores 14.2 (SD, 7.7), traumatic brain injury due to fall (50%), preadmission loss of consciousness (48%), and abnormal head CT scan (97%). Thirty-one children underwent 56 autoregulation tests. Impaired cerebral autoregulation occurred in 15 children (48.4%) who underwent 19 tests; 68% and 32% of tests demonstrated unilateral and bilateral impairment, respectively. Compared with children on median day 6 of admission after traumatic brain injury, impaired autoregulation was most common in the first 5 days after traumatic brain injury (day 1: relative risk, 3.7; 95% CI, 1.9-7.3 vs day 2: relative risk, 2.7; 95% CI, 1.1-6.5 vs day 5: relative risk, 1.33; 95% CI, 0.7-2.3). Children with impaired autoregulation were older (12.3 yr [SD, 1.3 yr] vs 8.7 yr [SD, 1.1 yr]; p = 0.04) and tended to have subdural hematoma (64% vs 44%), epidural hematoma (29% vs 17%), and subarachnoid hemorrhage (36% vs 28%). Eight children (53%) were discharged home with ongoing impaired cerebral autoregulation. CONCLUSIONS: Impaired cerebral autoregulation is common in children with complex mild traumatic brain injury, despite reassuring admission Glasgow Coma Scale 13-15. Children with complex mild traumatic brain injury have abnormal cerebrovascular hemodynamics, mostly during the first 5 days. Impairment commonly extends to the contralateral hemisphere and discharge of children with ongoing impaired cerebral autoregulation is common.

OBJECT: Traumatic intracranial hemorrhage (TICH) patients with acute kidney injury (AKI) were reported to have a high mortality rate. Renal replacement therapy (RRT) is indicated for patients with a severe kidney injury. This study aimed to compare the effects of different RRT modalities regarding chronic dialysis rate among adult TICH patients with AKI. METHODS: A retrospective search of computerized hospital records from 2000 to 2010 for patients with a discharge diagnosis of TICH was conducted to identify the index cases. We collected the data of TICH patients with increased intracranial pressure combined with severe AKI who received intermittent hemodialysis (IHD) or continuous veno-venous hemofiltration (CVVH) as RRT. The outcome was dialysis dependence between 2000 and 2010. RESULTS: From a total of 310 patients who were enrolled in the study, 134 (43%) received CVVH and 176 (57%) received IHD. The risk of dialysis dependency was significantly lower in the CVVH group than in the IHD group (adjusted hazard ratio: 0.368, 95% CI, 0.158-0.858, P = 0.034). Diabetes mellitus and coronary artery disease were risk factors for dialysis dependency. CVVH compared with IHD modality was associated with lower dialysis dependency rate in TICH patients combined with AKI and diabetes mellitus and those with an injury severity score (ISS) ≥16. CONCLUSION: CVVH may yield better renal outcomes than IHD among TICH patients with AKI, especially those with diabetes mellitus and an ISS ≥16. The beneficial impact of CVVH on TICH patients needs to be clarified in a large cohort study in future.

BACKGROUND: The exact mechanism, incidence, and risk factors for cerebral vasospasm after traumatic intracranial hemorrhage (ICH) continue to be poorly characterized. The incidence of post-traumatic vasospasm (PTV) varies depending on the detection modality. OBJECTIVE: We aimed to shed light on the predictors, associations, and true incidence of cerebral vasospasm after traumatic ICH using digital subtraction angiography (DSA) as the gold standard. METHODS: We examined a prospectively maintained database of traumatic brain injury (TBI) patients to identify patients with ICH secondary to TBI enrolled between 2002 and 2015 at our trauma center. Patients with TBI-associated ICH and evidence of elevated velocities on transcranial Doppler and computed tomography angiograms, confirmed with DSA were included. The diagnostic cerebral angiograms were evaluated by 2 blinded neurointerventionalists for cerebral vasospasm. Statistical analyses were conducted to determine predictors of PTV. RESULTS: Twenty patients with ICH secondary to TBI and evidence of vasospasm underwent DSAs. Seven patients (7/20; 35%) with traumatic ICH developed cerebral vasospasm and of those, 1 developed delayed cerebral ischemia (1/7; 14%). Of these 7 patients, 6 presented with subarachnoid hemorrhage (6/7; 85%). Vasospasm was substantially more common in patients with a Glasgow Coma Scale <9 (P = 0.017) than in all other groups. CONCLUSIONS: PTV as demonstrated by DCA may be more common than previously reported. Patients who exhibit PTV were more likely to have a Glasgow Coma Scale <9. This subgroup of patients may benefit from more systematic screening for the development of PTV, and earlier monitoring for signs of delayed cerebral ischemia.
