Pina C, Marco CA. Intoxication and Glasgow coma scale scores in patients with head trauma. Am J Emerg Med 2024; 80:8-10. [PMID: 38461650 DOI: 10.1016/j.ajem.2024.02.039] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/30/2023] [Revised: 02/19/2024] [Accepted: 02/25/2024] [Indexed: 03/12/2024] Open
Abstract
INTRODUCTION The Glasgow Coma Scale (GCS) is an assessment tool commonly used by emergency department (ED) clinicians to objectively describe level of consciousness, especially in trauma patients. This study aims to assess the effect of drug and alcohol intoxication on GCS scores in cases of traumatic head injury. METHODS In this retrospective chart review study, data were extracted from The Pennsylvania Trauma Systems Foundation Data Base Collection System. Eligible subjects included trauma patients aged 18 years and older, with head trauma, who presented between January 2019 and August 2023. Subjects were matched to controls who did not test positive for drugs or alcohol, matched by Injury Severity Score (ISS) category. RESULTS Among 1088 subjects, the mean age was 63 (95% CI 62-64). The mean Injury Severity Score was 21 (95% CI 21-22). The median GCS among all subjects was 14 (IQR 6-15). Cases with alcohol or drug use were matched to controls without alcohol or drug use, and were matched by categories of Injury Severity Score. Cases with alcohol or drug use had lower GCS (median 13; IQR 3-15), compared to cases without alcohol or drug use (median 15; IQR 13-15) (p < 0.0001, Wilcoxon Rank Sum Test). CONCLUSIONS Among patients with head trauma, intoxicated patients had statistically significant lower GCS scores as compared to matched patients with similar Injury Severity Scores.

Abstract
BACKGROUND The Glasgow coma score (GCS) is a clinical tool used to measure level of consciousness in traumatic brain injury and other settings. Despite its widespread use, there are many inaccuracies in its reporting. One source of inaccuracy is confounding factors which affect consciousness as well as each sub-score of the GCS. The purpose of this article was to create a comprehensive list of confounding factors in order to improve the accuracy of the GCS and ultimately improve decision-making. METHODS An English language literature search was conducted discussing GCS and multiple other keywords. Ultimately, 64 out of 3972 articles were included for further analysis. RESULTS A multitude of confounding factors were identified which may affect consciousness or GCS sub-scores including the eye exam, motor exam and the verbal response. CONCLUSIONS An up-to-date comprehensive list of confounding factors has been created that may be used to aide in GCS recording in hopes of improving its accuracy and utility.

Abstract
Cranioplasty involves the surgical reconstruction of cranial defects arising as a result of various factors, including decompressive craniectomy, cranial malformations, and brain injury due to road traffic accidents. Most of the modern decompressive craniectomies (DC) warrant a future cranioplasty surgery within 6-36 months. The conventional process of capturing the defect impression and polymethyl methacrylate (PMMA) flap fabrication results in a misfit or misalignment at the site of implantation. Equally, the intra-operative graft preparation is arduous and can result in a longer surgical time, which may compromise the functional and aesthetic outcomes. As part of a multicentric pilot clinical study, we recently conducted a cohort study on ten human subjects during 2019-2022, following the human ethics committee approvals from the participating institutes. In the current study, an important aspect of measuring the extent of bone remodelling during the time gap between decompressive craniectomy and cranioplasty was successfully evaluated. The sterilised PMMA bone flaps were implanted at the defect area during the cranioplasty surgery using titanium mini plates and screws. The mean surgery time was 90 ± 20 min, comparable to the other clinical studies on cranioplasty. No signs of intra-operative and post-operative complications, such as cerebrospinal fluid leakage, hematoma, or local and systemic infection, were clinically recorded. Importantly, aesthetic outcomes were excellent for all the patients, except in a few clinical cases, wherein the PMMA bone flap was to be carefully customized due to the remodelling of the native skull bone. The extent of physiological remodelling was evaluated by superimposing the pre-operative and post-operative CT scan data after converting the defect morphology into a 3D model. This study further establishes the safety and efficacy of a technologically better approach to fabricate patient-specific acrylic bone flaps with improved surgical outcomes. More importantly, the study outcome further demonstrates the strategy to address bone remodelling during the patient-specific implant design.

Abstract
Moderate traumatic brain injury (TBI) is a diagnosis that describes diverse patients with heterogeneity of primary injuries. Defined by a Glasgow Coma Scale between 9 and 12, this category includes patients who may neurologically worsen and require increasing intensive care resources and/or emergency neurosurgery. Despite the unique characteristics of these patients, there have not been specific guidelines published before this effort to support decision-making in these patients. A Delphi consensus group from the Latin American Brain Injury Consortium was established to generate recommendations related to the definition and categorization of moderate TBI. Before an in-person meeting, a systematic review of the literature was performed identifying evidence relevant to planned topics. Blinded voting assessed support for each recommendation. A priori the threshold for consensus was set at 80% agreement. Nine PICOT questions were generated by the panel, including definition, categorization, grouping, and diagnosis of moderate TBI. Here, we report the results of our work including relevant consensus statements and discussion for each question. Moderate TBI is an entity for which there is little published evidence available supporting definition, diagnosis, and management. Recommendations based on experts' opinion were informed by available evidence and aim to refine the definition and categorization of moderate TBI. Further studies evaluating the impact of these recommendations will be required.

Abstract
Traumatic Brain Injury (TBI) is a prevalent disorder mostly characterized by persistent impairments in cognitive function that poses a substantial burden on caregivers and the healthcare system worldwide. Crucially, severity classification is primarily based on clinical evaluations, which are non-specific and poorly predictive of long-term disability. In this Mini Review, we first provide a description of our model-free and model-based approaches within the turbulent dynamics framework as well as our vision on how they can potentially contribute to provide new neuroimaging biomarkers for TBI. In addition, we report the main findings of our recent study examining longitudinal changes in moderate-severe TBI (msTBI) patients during a one year spontaneous recovery by applying the turbulent dynamics framework (model-free approach) and the Hopf whole-brain computational model (model-based approach) combined with in silico perturbations. Given the neuroinflammatory response and heightened risk for neurodegeneration after TBI, we also offer future directions to explore the association with genomic information. Moreover, we discuss how whole-brain computational modeling may advance our understanding of the impact of structural disconnection on whole-brain dynamics after msTBI in light of our recent findings. Lastly, we suggest future avenues whereby whole-brain computational modeling may assist the identification of optimal brain targets for deep brain stimulation to promote TBI recovery.

Surgery 2024; 175:907-912. [PMID: 37981556 DOI: 10.1016/j.surg.2023.09.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/09/2023] [Revised: 09/13/2023] [Accepted: 09/26/2023] [Indexed: 11/21/2023]
Abstract
BACKGROUND Amantadine is used in the post-acute care setting to improve cognitive function after a traumatic brain injury. Its utility in the acute postinjury period is unknown. In this pilot study, we sought to examine the effect of amantadine on short-term cognitive disability among patients with a severe traumatic brain injury and hypothesized that patients receiving amantadine would have a greater improvement in disability throughout their acute hospitalization. METHODS We performed a prospective, observational study of patients ≥18 years with severe traumatic brain injury (Glasgow Coma Scale ≤8) at a level I trauma center between 2020 and 2022. Patients with penetrating trauma, death within 48 hours of admission, and no radiographic evidence of intracranial pathology were excluded. Patients were grouped according to whether they received amantadine. Our primary outcome was the change in cognitive disability, measured by the Disability Rating Scale (DRS), over the index hospitalization. RESULTS There were 55 patients in the cohort: 41.8% (n = 23) received amantadine and 58.2% (n = 32) did not. There were higher rates of motor vehicle collisions (65.2% vs 46.9%, P = .02), diffuse axonal injury (47.8% vs 18.8%, P = .02), intracranial pressure monitor use (73.9% vs 21.9%, P = .0001), and propranolol use (73.9% vs 21.9%, P = .0001) in the amantadine. There was a larger improvement in DRS scores among patients receiving amantadine (7.8 vs 3.6, P = .001), and amantadine independently predicted improvement in DRS scores (β, 1.61; 95% confidence interval, 0.20-3.02, P = .03). Rates of discharge to traumatic brain injury rehabilitation were significantly higher in the amantadine group (73.9% vs 21.9%, P = .0002). CONCLUSION Among patients with severe traumatic brain injury, amantadine use in the acute postinjury period may be associated with an improvement in cognitive disability and discharge to traumatic brain injury rehabilitation.

Abstract
Background The base deficit, international normalized ratio, and Glasgow Coma Scale (BIG) score was previously developed to predict the outcomes of pediatric trauma patients. We designed this study to explore and improve the prognostic value of the BIG score in adult patients with traumatic brain injury (TBI). Methods Adult patients diagnosed with TBI in a public critical care database were included in this observational study. The BIG score was calculated based on the Glasgow Coma Scale (GCS), the international normalized ratio (INR), and the base deficit. Logistic regression analysis was performed to confirm the association between the BIG score and the outcome of included patients. Receiver operating characteristic (ROC) curves were drawn to evaluate the prognostic value of the BIG score and novel constructed models. Results In total, 1,034 TBI patients were included in this study with a mortality of 22.8%. Non-survivors had higher BIG scores than survivors (p < 0.001). The results of multivariable logistic regression analysis showed that age (p < 0.001), pulse oxygen saturation (SpO2) (p = 0.032), glucose (p = 0.015), hemoglobin (p = 0.047), BIG score (p < 0.001), subarachnoid hemorrhage (p = 0.013), and intracerebral hematoma (p = 0.001) were associated with in-hospital mortality of included patients. The AUC (area under the ROC curves) of the BIG score was 0.669, which was not as high as in previous pediatric trauma cohorts. However, combining the BIG score with age increased the AUC to 0.764. The prognostic model composed of significant factors including BIG had the highest AUC of 0.786. Conclusion The age-adjusted BIG score is superior to the original BIG score in predicting mortality of adult TBI patients. The prognostic model incorporating the BIG score is beneficial for clinicians, aiding them in making early triage and treatment decisions in adult TBI patients.

Abstract
BACKGROUND Intentional injuries, including self-harm, suicide, conflict, and interpersonal violence are a significant public health concern in Iran, but they have not been adequately documented. This study aimed to investigate intentional injuries in cases admitted to Sina Hospital in Tehran, Iran, affiliated with the National Trauma Registry of Iran. Study Design: A retrospective cohort study. METHODS A registry-based study on the characteristics of 852 intentional injury cases was conducted from 2016 to 2023. Information on various aspects, including baseline characteristics, injury characteristics, and injury outcomes was compared between groups of self-harm/suicide, conflict/interpersonal violence, and others (abuse and legal prosecution). RESULTS Of 6,692 registered trauma cases, 852 (12.7%) had intentional injuries. Men accounted for 92 (77.3%) self-harm/suicide and 650 (96.4%) conflict/interpersonal violence cases (P<0.001). Self-harm/ suicide mostly occurred at home in 89 (74.8%) cases, while 73 (10.8%) conflict/interpersonal violence cases happened at home (P<0.001). Falls were the cause of trauma in 12 (10.1%) self-harm/suicide cases compared to 7 (1.0%) conflict/interpersonal violence cases (P<0.001). Furthermore, blunt trauma was the cause of trauma in one (0.8%) case of self-harm/suicide and 66 (9.8%) conflict/interpersonal violence cases (P<0.001). Moreover, 14 (11.8%) self-harm/suicide and 34 (5.0%) conflict/interpersonal violence cases required ventilation (P=0.010). Additionally, 74 (8.7%) intentional injury cases had multiple traumas, which were seen in nine (7.6%) self-harm/suicide and 58 (8.6%) conflict/interpersonal violence cases (P<0.001). CONCLUSION Men were the majority of self-harm/suicide and conflict/interpersonal violence cases. Self-harm/suicide incidents mostly occurred at home and resulted in more injuries from falls, while conflict/ interpersonal violence resulted in increased blunt traumas and multiple traumas.

Evaluating the state of non-invasive imaging biomarkers for traumatic brain injury. Neurosurg Rev 2023; 46:232. [PMID: 37682375 DOI: 10.1007/s10143-023-02085-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/25/2023] [Revised: 07/03/2023] [Accepted: 07/07/2023] [Indexed: 09/09/2023]
Abstract
Non-invasive imaging biomarkers are useful for prognostication in patients with traumatic brain injury (TBI) at high risk for morbidity with invasive procedures. The authors present findings from a scoping review discussing the pertinent biomarkers. Embase, Ovid-MEDLINE, and Scopus were queried for original research on imaging biomarkers for prognostication of TBI in adult patients. Two reviewers independently screened articles, extracted data, and evaluated risk of bias. Data was synthesized and confidence evaluated with the linked evidence according to the Grades of Recommendation, Assessment, Development, and Evaluation (GRADE) approach. Our search yielded 3104 unique citations, 44 of which were included in this review. Study populations varied in TBI severity, as defined by Glasgow Coma Scale (GCS), including: mild (n=9), mild and moderate (n=3), moderate and severe (n=7), severe (n=6), and all GCS scores (n=17). Diverse imaging modalities were used for prognostication, predominantly computed tomography (CT) only (n=11), magnetic resonance imaging (MRI) only (n=9), and diffusion tensor imaging (DTI) (N=9). The biomarkers included diffusion coefficient mapping, metabolic characteristics, optic nerve sheath diameter, T1-weighted signal changes, cortical cerebral blood flow, axial versus extra-axial lesions, T2-weighted gradient versus spin echo, translocator protein levels, and trauma imaging of brainstem areas. The majority (93%) of studies identified that the imaging biomarker of interest had a statistically significant prognostic value; however, these are based on a very low to low level of quality of evidence. No study directly compared the effects on specific TBI treatments on the temporal course of imaging biomarkers. The current literature is insufficient to make a strong recommendation about a preferred imaging biomarker for TBI, especially considering GRADE criteria revealing low quality of evidence. Rigorous prospective research of imaging biomarkers of TBI is warranted to improve the understanding of TBI severity.

Abstract
Background: Trauma is still a major cause of mortality in people < 50 years of age. Biomarkers are needed to estimate the severity of the condition and the patient outcome. Methods: Cell-free DNA (cfDNA) and further laboratory markers were determined in plasma and serum of 164 patients at time of admission to the emergency room. Among them were 64 patients with severe trauma (Injury Severity Score (ISS) ≥ 16), 51 patients with moderate trauma (ISS < 16) and 49 patients with single fractures (24 femur neck and 25 ankle fractures). Disease severity was objectified by ISS and Glasgow Coma Scale (GCS). Results: cfDNA levels in plasma and serum were significantly higher in patients with severe multiple trauma (SMT) than in those with moderate trauma (p = 0.002, p = 0.003, respectively) or with single fractures (each p < 0.001). CfDNA in plasma and serum correlated very strongly with each other (R = 0.91; p < 0.001). The AUC in ROC curves for identification of SMT patients was 0.76 and 0.74 for cfDNA in plasma and serum, respectively—this was further increased to 0.84 by the combination of cfDNA and hemoglobin. Within the group of multiple trauma patients, cfDNA levels were significantly higher in more severely injured patients and patients with severe traumatic brain injury (GCS ≤ 8 versus GCS > 8). Thirteen (20.3%) of the multiple trauma patients died during the first week after trauma. Levels of cfDNA were significantly higher in non-surviving patients than in survivors (p < 0.001), reaching an AUC of 0.81 for cfDNA in both, plasma and serum, which was further increased by the combination with hemoglobin and leukocytes. Conclusions: cfDNA is valuable for estimation of trauma severity and prognosis of trauma patients.

Basak D, Chatterjee S, Attergrim J, Sharma MR, Soni KD, Verma S, GerdinWärnberg M, Roy N. Glasgow coma scale compared to other trauma scores in discriminating in-hospital mortality of traumatic brain injury patients admitted to urban Indian hospitals: A multicentre prospective cohort study. Injury 2023; 54:93-99. [PMID: 36243583 DOI: 10.1016/j.injury.2022.09.035] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 01/13/2022] [Revised: 09/15/2022] [Accepted: 09/20/2022] [Indexed: 02/02/2023]
Abstract
BACKGROUND Glasgow Coma Scale (GCS) is one of the most commonly used trauma scores and is a good predictor of outcome in traumatic brain injury (TBI) patients. There are other more complex scores with additional physiological parameters. Whether they discriminate better than GCS in predicting mortality in TBI patients is debatable. The aim of this study was to compare the discrimination of GCS with that of MGAP, GAP, RTS and KTS for 24-hour and 30-day in-hospital mortality in adult TBI patients, in a resource limited LMIC setting. METHOD We analysed data from the multicentre, observational trauma cohort Towards Improved Trauma Care Outcome (TITCO) in India. We included all patients 18 years or older, admitted from the emergency department with TBI. The Area Under the Receiver Operating Characteristic (AUROC) curve was used to quantify and compare the discrimination of all scores: GCS; Revised Trauma Score (RTS); mechanism, GCS, age, systolic blood pressure (MGAP); GCS, age, systolic blood pressure (GAP) and Kampala Trauma Score (KTS) in the prediction of 24-hour and 30-day in-hospital mortality. RESULTS A total of 3306 TBI patients were included in this study. The majority were within the GCS range 3-8. The commonest mechanism of injury was road traffic injuries [1907(58.0%)]. In-hospital mortality was 27.2% (899). There was no significant difference in discrimination in 24-hour in-hospital mortality when comparing GCS with MGAP and GAP. While GCS performed better than KTS, RTS performed better than GCS. For 30-day in-hospital mortality, GCS discriminated significantly better compared with KTS, but there was no significant difference when compared to MGAP and RTS. GAP discriminated significantly better when compared with GCS. CONCLUSION This study shows that the discrimination of GCS is comparable to that of more complex trauma scores in predicting 24-hour and 30-day in-hospital mortality in adult TBI patients in a resource limited LMIC setting.

Abstract
BACKGROUND Older adults have the highest traumatic brain injury (TBI)-related morbidity and mortality, and rates in older adults are increasing, chiefly due to falls. OBJECTIVE This study used hierarchical linear modeling (HLM) to examine baseline predictors of functional independence trajectories across 1, 2, 5, and 10 years after TBI in older adults. METHODS Participants comprised 2,459 individuals aged 60 or older at the time of TBI, enrolled in the longitudinal TBI Model Systems database, and had Functional Independence Measure Motor and Cognitive subscale scores and Glasgow Outcome Scale-Extended scores during at least 1 time point. RESULTS Functional independence trajectories generally declined over the 10 years after TBI. Individuals who were older, male, underrepresented minorities, had lower education, were unemployed at time of injury, had no history of substance use disorder, or had difficulties with learning, dressing, and going out of the home prior to the TBI, or longer time in posttraumatic amnesia had lower functional independence trajectories across at least one of the functional independence outcomes. CONCLUSION These predictors of functional independence in older adults with TBI may heighten awareness of these factors in treatment planning and long-term health monitoring and ultimately as a way to decrease morbidity and mortality.

Abstract
OBJECTIVE The objective of this article was to compare children with traumatic brain injury (TBI) and Glasgow Coma Scale score (GCS) 13 with children presenting with GCS 14 and 15 and GCS 9 to 12. DATA SOURCE We searched PubMed for clinical studies of children of 0 to 18 years of age with mild TBI (mTBI) and moderate TBI, published in English language in the period of 2000 to 2020. STUDY SELECTION We selected studies sub-classifying children with GCS 13 in comparison with GCS 14 and 15 and 9 to 12. We excluded reviews, meta-analyses, non-U.S./European population studies, studies of abusive head trauma, and severe TBI. DATA SYNTHESIS Most children (>85%) with an mTBI present at the emergency department with an initial GCS 15. A minority of only 5% present with GCS 13, 40% of which sustain a high-energy trauma. Compared with GCS 15, they present with a longer duration of unconsciousness and of post-traumatic amnesia. More often head computerized tomography scans show abnormalities (in 9-16%), leading to neurosurgical intervention in 3 to 8%. Also, higher rates of severe extracranial injury are reported. Admission is indicated in more than 90%, with a median length of hospitalization of more than 4 days and 28% requiring intensive care unit level care. These data are more consistent with children with GCS 9 to 12. In children with GCS 15, all these numbers are much lower. CONCLUSION We advocate classifying children with GCS 13 as moderate TBI and treat them accordingly.

Abstract
Neuroethical questions raised by recent advances in the diagnosis and treatment of disorders of consciousness are rapidly expanding, increasingly relevant, and yet underexplored. The aim of this thematic review is to provide a clinically applicable framework for understanding the current taxonomy of disorders of consciousness and to propose an approach to identifying and critically evaluating actionable neuroethical issues that are frequently encountered in research and clinical care for this vulnerable population. Increased awareness of these issues and clarity about opportunities for optimizing ethically-responsible care in this domain are especially timely given recent surges in critically ill patients with unusually prolonged disorders of consciousness associated with coronavirus disease 2019 (COVID-19) around the world. We begin with an overview of the field of neuroethics: what it is, its history and evolution in the context of biomedical ethics at large. We then explore nomenclature used in disorders of consciousness, covering categories proposed by the American Academy of Neurology, the American Congress of Rehabilitation Medicine, and the National Institute on Disability, Independent Living, and Rehabilitation Research, including definitions of terms such as coma, the vegetative state, unresponsive wakefulness syndrome, minimally conscious state, covert consciousness, and the confusional state. We discuss why these definitions matter, and why there has been such evolution in this nosology over the years, from Jennett and Plum in 1972 to the Multi-Society Task Force in 1994, the Aspen Working Group in 2002 and up until the 2018 American and 2020 European Disorders of Consciousness guidelines. We then move to a discussion of clinical aspects of disorders of consciousness, the natural history of recovery, and ethical issues that arise within the context of caring for persons with disorders of consciousness. We conclude with a discussion of key challenges associated with assessing residual consciousness in disorders of consciousness, potential solutions and future directions, including integration of crucial disability rights perspectives.

Abstract
Background: We aimed to assess the prognostic value of Rotterdam and Marshall scoring systems to predict in-hospital mortality in patients with traumatic brain injury (TBI).Methods: A retrospective analysis was conducted for patients with TBI who underwent head computerized tomography (CT) scan at a Level I trauma center between 2011 and 2018. Receiver operating characteristic (ROC) curves were used to determine the cutoff values for predicting in-hospital mortality.Results: A total of 1035 patients with TBI were included with a mean age of 30 years. The mean Rotterdam and Marshall scores were higher among non-survivors (p = .001). Patients with higher Rotterdam (>3) or Marshall (>2) CT scores were older, had higher injury severity scores and in-hospital mortality and had lower GCS and blood ethanol levels than those with lower scores. The cutoff point of Rotterdam score was 3.5 (sensitivity, 61.2%; specificity, 85.6%) and Marshall score was 2.5 (74.3% sensitivity and 76.3% specificity). Multivariable logistic regression analyses showed that Marshall and Rotterdam scoring systems were independent predictors of mortality (odds ratio 8.4; 95% confidence interval 4.95-14.17 and odds ratio 4.4; 95% confidence interval 2.36-9.39, respectively).Conclusion: Rotterdam and Marshall CT scores have independent prognostic values in patients with TBI even in alcoholic patients.

Abstract
OBJECTIVE Severe traumatic brain injury (sTBI) is accompanied by significant declines in self-rated health (SRH). Although such deteriorations in SRH are related to various consequences of sTBI, the effect of posttraumatic reactions (i.e., posttraumatic stress [PTS] symptoms) has been tested insufficiently to date, especially among civilians. The present investigation is based on Trajectories of Recovery After Severe Traumatic brain injury-Matters In families (TRAST-MI), a unique study among civilians with sTBI and their families. Previous research revealed that civilian sTBI has effects beyond the injured patient, influencing their close relatives as well. The aim of this study was to assess the association between PTS symptoms and SRH among patients with civilian sTBI and their close relatives. METHODS Patients with sTBI (assessed by an Abbreviated Injury Scale of the head region score >3) and their close relatives participated in TRAST-MI. One hundred twenty-six patient-relative dyads were assessed at 3, 6, and 12 months after the injury. RESULTS Multilevel modeling revealed that patients' PTS symptoms were associated with consequent SRH (slope = 0.42; p < .001), and relatives' PTS symptoms were associated with their respective SRH (slope = 0.2; p = .012). CONCLUSIONS The findings of this study reveal that SRH of both patients with sTBI and their relatives are negatively affected by their own PTS symptoms. These findings underline the understanding that sTBI is not merely a medical trauma but rather a comprehensive psychosocial trauma, which has consequences for the whole family system.

Abstract
OBJECTIVES We developed a tool, Serial Neurologic Assessment in Pediatrics, to screen for neurologic changes in patients, including those who are intubated, are sedated, and/or have developmental disabilities. Our aims were to: 1) determine protocol adherence when performing Serial Neurologic Assessment in Pediatrics, 2) determine the interrater reliability between nurses, and 3) assess the feasibility and acceptability of using Serial Neurologic Assessment in Pediatrics compared with the Glasgow Coma Scale. DESIGN Mixed-methods, observational cohort. SETTING Pediatric and neonatal ICUs. SUBJECTS Critical care nurses and patients. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Serial Neurologic Assessment in Pediatrics assesses Mental Status, Cranial Nerves, Communication, and Motor Function, with scales for children less than 6 months, greater than or equal to 6 months to less than 2 years, and greater than or equal to 2 years old. We assessed protocol adherence with standardized observations. We assessed the interrater reliability of independent Serial Neurologic Assessment in Pediatrics assessments between pairs of trained nurses by percent- and bias- adjusted kappa and percent agreement. Semistructured interviews with nurses evaluated acceptability and feasibility after nurses used Serial Neurologic Assessment in Pediatrics concurrently with Glasgow Coma Scale during routine care. Ninety-eight percent of nurses (43/44) had 100% protocol adherence on the standardized checklist. Forty-three nurses performed 387 paired Serial Neurologic Assessment in Pediatrics assessments (149 < 6 mo; 91 ≥ 6 mo to < 2 yr, and 147 ≥ 2 yr) on 299 patients. Interrater reliability was substantial to near-perfect across all components for each age-based Serial Neurologic Assessment in Pediatrics scale. Percent agreement was independent of developmental disabilities for all Serial Neurologic Assessment in Pediatrics components except Mental Status and lower extremity Motor Function for patients deemed "Able to Participate" with the assessment. Nurses reported that they felt Serial Neurologic Assessment in Pediatrics, compared with Glasgow Coma Scale, was easier to use and clearer in describing the neurologic status of patients who were intubated, were sedated, and/or had developmental disabilities. About 92% of nurses preferred to use Serial Neurologic Assessment in Pediatrics over Glasgow Coma Scale. CONCLUSIONS When used by critical care nurses, Serial Neurologic Assessment in Pediatrics has excellent protocol adherence, substantial to near-perfect interrater reliability, and is feasible to implement. Further work will determine the sensitivity and specificity for detecting clinically meaningful neurologic decline.

Abstract
Hyperglycemia during sepsis is associated with increased organ dysfunction and higher mortality. The role of the host immune response in development of hyperglycemia during sepsis remains unclear. We performed a retrospective analysis of critically ill adult septic patients requiring mechanical ventilation (n = 153) to study the relationship between hyperglycemia and ten markers of the host injury and immune response measured on the first day of ICU admission (baseline). We determined associations between each biomarker and: (1) glucose, insulin, and c-peptide levels at the time of biomarker collection by Pearson correlation; (2) average glucose and glycemic variability in the first two days of ICU admission by linear regression; and (3) occurrence of hyperglycemia (blood glucose>180mg/dL) by logistic regression. Results were adjusted for age, pre-existing diabetes mellitus, severity of illness, and total insulin and glucocorticoid dose. Baseline plasma levels of ST2 and procalcitonin were positively correlated with average blood glucose and glycemic variability in the first two days of ICU admission in unadjusted and adjusted analyses. Additionally, higher baseline ST2, IL-1ra, procalcitonin, and pentraxin-3 levels were associated with increased risk of hyperglycemia. Our results suggest associations between the host immune response and hyperglycemia in critically ill septic patients particularly implicating the interleukin-1 axis (IL-1ra), the interleukin-33 axis (ST2), and the host response to bacterial infections (procalcitonin, pentraxin-3).

Salottolo K, Panchal R, Madayag RM, Dhakal L, Rosenberg W, Banton KL, Hamilton D, Bar-Or D. Incorporating age improves the Glasgow Coma Scale score for predicting mortality from traumatic brain injury. Trauma Surg Acute Care Open 2021; 6:e000641. [PMID: 33634212 PMCID: PMC7880096 DOI: 10.1136/tsaco-2020-000641] [Citation(s) in RCA: 4] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/10/2020] [Revised: 01/05/2021] [Accepted: 01/29/2021] [Indexed: 12/19/2022] Open
Abstract
Background The Glasgow Coma Scale (GCS) score has been adapted into categories of severity (mild, moderate, and severe) and are ubiquitous in the trauma setting. This study sought to revise the GCS categories to account for an interaction by age and to determine the discrimination of the revised categories compared with the standard GCS categories. Methods The American College of Surgeons National Trauma Data Bank registry was used to identify patients with traumatic brain injury (TBI; ICD-9 codes 850-854.19) who were admitted to participating trauma centers from 2010 to 2015. The primary exposure variables were GCS score and age, categorized by decade (teens, 20s, 30s…, 80s). In-hospital mortality was the primary outcome for examining TBI severity/prognostication. Logistic regression was used to calculate the conditional probability of death by age decade and GCS in a development dataset (75% of patients). These probabilities were used to create a points-based revision of the GCS, categorized as low (mild), moderate, and high (severe). Performance of the revised versus standard GCS categories was compared in the validation dataset using area under the receiver operating characteristic (AUC) curves. Results The final population included 539,032 patients with TBI. Age modified the performance of the GCS, resulting in a novel categorization schema for each age decile. For patients in their 50s, performance of the revised GCS categories mirrored the standard GCS categorization (3-8, 9-12, 13-15); all other revised GCS categories were heavily modified by age. Model validation demonstrated the revised GCS categories statistically significantly outperformed the standard GCS categories at predicting mortality (AUC: 0.800 vs 0.755, p<0.001). The revised GCS categorization also outperformed the standard GCS categories for mortality within pre-specified subpopulations: blunt mechanism, isolated TBI, falls, non-transferred patients. Discussion We propose the revised age-adjusted GCS categories will improve severity assessment and provide a more uniform early prognostic indicator of mortality following traumatic brain injury. Level of evidence III epidemiologic/prognostic.

Assessing the Severity of Traumatic Brain Injury-Time for a Change? J Clin Med 2021; 10:jcm10010148.

Abstract
Traumatic brain injury (TBI) has been described to be man's most complex disease, in man's most complex organ. Despite this vast complexity, variability, and individuality, we still classify the severity of TBI based on non-specific, often unreliable, and pathophysiologically poorly understood measures. Current classifications are primarily based on clinical evaluations, which are non-specific and poorly predictive of long-term disability. Brain imaging results have also been used, yet there are multiple ways of doing brain imaging, at different timepoints in this very dynamic injury. Severity itself is a vague concept. All prediction models based on combining variables that can be assessed during the acute phase have reached only modest predictive values for later outcome. Yet, these early labels of severity often determine how the patient is treated by the healthcare system at large. This opinion paper examines the problems and provides caveats regarding the use of current severity labels and the many practical and scientific issues that arise from doing so. The objective of this paper is to show the causes and consequences of current practice and propose a new approach based on risk classification. A new approach based on multimodal quantifiable data (including imaging and biomarkers) and risk-labels would be of benefit both for the patients and for TBI clinical research and should be a priority for international efforts in the field.

Abstract
Trauma brain injury (TBI) is the most common cause of death and disability in young adults. A method to determine the probability of survival (Ps) in trauma called iterative random comparison classification (IRCC) was developed and its performance was evaluated in TBI. IRCC operates by iteratively comparing the test case with randomly chosen subgroups of cases from a database of known outcomes (survivors and not survivors) and determines the overall percentage match. The performance of IRCC to determine Ps in TBI was compared with two existing methods. One was Ps14 that uses regression and the other was predictive statistical diagnosis (PSD) that is based on Bayesian statistic. The TBI database contained 4124 adult cases (mean age 67.9 years, standard deviation 21.6) of which 3553 (86.2%) were survivors and 571 (13.8%) were not survivors. IRCC determined Ps for the survivors and not survivors with an accuracy of 79.0 and 71.4%, respectively, while the corresponding values for Ps14 were 97.4% (survivors) and 40.2% (not survivors) and for PSD were 90.8% (survivors) and 50% (not survivors). IRCC could be valuable for determining Ps in TBI and with a suitable database in other traumas.

Abstract
BACKGROUND Emergency physicians on-scene provide highly specialized care to severely sick or injured patients. High-quality research relies on the quality of data, but no commonly accepted definition of EMS data quality exits. Glasgow Coma Score (GCS) and Systolic Blood Pressure (SBP) are core physiological variables, but little is known about the quality of these data when reported in p-EMS research. This systematic review aims to describe the quality of pre-hospital reporting of GCS and SBP data in studies where emergency physicians are present on-scene. METHODS A systematic literature search was performed using CINAHL, Cochrane, Embase, Medline, Norart, Scopus, SweMed + and Web of Science, in accordance with the PRISMA guidelines. Reported data on accuracy of reporting, completeness and capture were extracted to describe the quality of documentation of GCS and SBP. External and internal validity assessment was performed by extracting a set of predefined variables. RESULTS We included 137 articles describing data collection for GCS, SBP or both. Most studies (81%) were conducted in Europe and 59% of studies reported trauma cases. Reporting of GCS and SBP data were not uniform and may be improved to enable comparisons. Of the predefined external and internal validity data items, 26%-45% of data were possible to extract from the included papers. CONCLUSIONS Reporting of GCS and SBP is variable in scientific papers. We recommend standardized reporting to enable comparisons of p-EMS.

Abstract
Moore, James, Martin J. MacInnis, Jon Dallimore, and Matt Wilkes. The Lake Louise Score: A Critical Assessment of Its Specificity. High Alt Med Biol. 21:237-242, 2020. Introduction: The Lake Louise Score (LLS) has low specificity for diagnosing acute mountain sickness (AMS). As this tool is used for research and clinical decision making, it is important to understand the origins of this poor specificity. We reviewed AMS diagnoses in a population trekking at low altitude ("false positives") to critically assess LLS specificity. Method: We retrospectively analyzed data from a sample of 123 adolescents trekking at low altitude to establish the predominant causes of false-positive AMS diagnoses (1993 LLS criteria), separately removing each LLS component to assess its contribution to the final score. Exploratory factor analysis (EFA) was applied to the data to establish component patterns. Results: Removal of LLS components individually showed fatigue contributed slightly more to false-positive AMS diagnoses than sleep quality in this group. An EFA from morning data highlighted sleep quality as a stand-alone factor in the measurement of AMS. Although of smaller significance, an EFA of the evening data highlighted fatigue and headache as the stand-alone factor. Conclusion: Our findings not only supported the recent removal of sleep quality from the LLS, but also demonstrated that fatigue had an equal part to play in the misdiagnosis of AMS in this population. These data highlighted the poor specificity of the LLS and suggest that the measurement of illness at altitude undergo further review.

Abstract
ObjectiveHead injury (HI) is a common presentation to emergency departments (EDs). The risk of clinically important traumatic brain injury (ciTBI) is low. We describe the relationship between Glasgow Coma Scale (GCS) scores at presentation and risk of ciTBI.MethodsPlanned secondary analysis of a prospective observational study of children<18 years who presented with HIs of any severity at 10 Australian/New Zealand centres. We reviewed all cases of ciTBI, with ORs (Odds Ratio) and their 95% CIs (Confidence Interval) calculated for risk of ciTBI based on GCS score. We used receiver operating characteristic (ROC) curves to determine the ability of total GCS score to discriminate ciTBI, mortality and need for neurosurgery.ResultsOf 20 137 evaluable patients with HI, 280 (1.3%) sustained a ciTBI. 82 (29.3%) patients underwent neurosurgery and 13 (4.6%) died. The odds of ciTBI increased steadily with falling GCS. Compared with GCS 15, odds of ciTBI was 17.5 (95% CI 12.4 to 24.6) times higher for GCS 14, and 484.5 (95% CI 289.8 to 809.7) times higher for GCS 3. The area under the ROC curve for the association between GCS and ciTBI was 0.79 (95% CI 0.77 to 0.82), for GCS and mortality 0.91 (95% CI 0.82 to 0.99) and for GCS and neurosurgery 0.88 (95% CI 0.83 to 0.92).ConclusionsOutside clinical decision rules, decreasing levels of GCS are an important indicator for increasing risk of ciTBI, neurosurgery and death. The level of GCS should drive clinician decision-making in terms of urgency of neurosurgical consultation and possible transfer to a higher level of care.

Abstract
Objectives: Variables collected early after severe traumatic brain injury (sTBI) could predict health-related quality of life (HRQoL). Our aim was to determine the prevalence of patients with a low HRQoL 4 years after sTBI and to develop a prediction model including early variables.Methods: Adult patients with both sTBI [abbreviated injury score of the head region (HAIS) >3] and disease-specific HRQoL assessments using the 'Quality of Life after Brain Injury' (QOLIBRI) were included. The outcome was the total score (TS) of QOLIBRI; cutoff for low HRQoL: <60 points. A multivariate logistic regression model and prediction model were performed.Results: One hundred-sixteen patients [median age 50.8 years (IQR 25.9-62.8; 21.6% >65 years)] were included; 68 (58.6%) with HAIS = 4, 48 (41.4%) with HAIS = 5. Median Glasgow Coma Scale (GCS) was 13 (IQR 3-15). Median TS was 77 (IQR 60-88). Low HRQoL was observed in 28 patients (24.1%). Two variables were associated with low HRQoL: GCS <13, working situation other than employed or retired. The prediction model had an AUROC of 0.765; calibration was moderate (Hosmer Lemeshow Chi2 6.82, p = .556).Conclusion: One in four patients had a low HRQoL after 4 years. A lower GCS and working situations were associated with low HRQoL.

Abstract
OBJECTIVES To examine the association of the base deficit, international normalized ratio, and Glasgow Coma Scale (BIG) score on emergency department arrival with functional dependence at hospital discharge (Pediatric Cerebral Performance Category ≥ 4) in pediatric multiple trauma patients with traumatic brain injury. DESIGN A retrospective cohort study of a pediatric trauma database from 2001 to 2018. SETTING Level 1 trauma program at a university-affiliated pediatric institution. PATIENTS Two to 17 years old children sustaining major blunt trauma including a traumatic brain injury and meeting trauma team activation criteria. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS Two investigators, blinded to the BIG score, determined discharge Pediatric Cerebral Performance Category scores. The BIG score was measured on emergency department arrival. The 609 study patients were 9.7 ± 4.4 years old with a median Injury Severity Score 22 (interquartile range, 12). One-hundred seventy-one of 609 (28%) had Pediatric Cerebral Performance Category greater than or equal to 4 (primary outcome). The BIG constituted a multivariable predictor of Pediatric Cerebral Performance Category greater than or equal to 4 (odds ratio, 2.39; 95% CI, 1.81-3.15) after adjustment for neurosurgery requirement (odds ratio, 2.83; 95% CI, 1.69-4.74), pupils fixed and dilated (odds ratio, 3.1; 95% CI, 1.49-6.38), and intubation at the scene or referral hospital (odds ratio, 2.82; 95% CI, 1.35-5.87) and other postulated predictors of poor outcome. The area under the BIG receiver operating characteristic curve was 0.87 (0.84-0.90). Using an optimal BIG cutoff less than or equal to 8, sensitivity and negative predictive value for functional dependence at discharge were 93% and 96%, respectively, compared with a sensitivity of 79% and negative predictive value of 91% with Glasgow Coma Scale less than or equal to 8. In children with Glasgow Coma Scale 3, the BIG score was associated with brain death (odds ratio, 2.13; 95% CI, 1.58-2.36). The BIG also predicted disposition to inpatient rehabilitation (odds ratio, 2.26; 95% CI, 2.17-2.35). CONCLUSIONS The BIG score is a simple, rapidly obtainable severity of illness score that constitutes an independent predictor of functional dependence at hospital discharge in pediatric trauma patients with traumatic brain injury. The BIG score may benefit Trauma and Neurocritical care programs in identifying ideal candidates for traumatic brain injury trials within the therapeutic window of treatment.

Abstract
OBJECTIVE To evaluate the safety and efficacy of Cerebrolysin as an add-on therapy to local standard treatment protocol in patients after moderate-to-severe traumatic brain injury. METHODS The patients received the study medication in addition to standard care (50 mL of Cerebrolysin or physiological saline solution daily for 10 days, followed by two additional treatment cycles with 10 mL daily for 10 days) in a prospective, randomized, double-blind, placebo-controlled, parallel-group, multi-centre phase IIIb/IV trial. The primary endpoint was a multidimensional ensemble of 14 outcome scales pooled to be analyzed by means of the multivariate, correlation-sensitive Wei-Lachin procedure. RESULTS In 46 enrolled TBI patients (Cerebrolysin 22, placebo 24), three single outcomes showed stand-alone statistically significant superiority of Cerebrolysin [Stroop Word/Dots Interference (p = 0.0415, Mann-Whitney(MW) = 0.6816, 95% CI 0.51-0.86); Color Trails Tests 1 and 2 (p = 0.0223/0.0170, MW = 0.72/0.73, 95% CI 0.53-0.90/0.54-0.91), both effect sizes lying above the benchmark for "large" superiority (MW > 0.71)]. While for the primary multivariate ensemble, statistical significance was just missed in the intention-to-treat population (pWei-Lachin < 0.1, MWcombined = 0.63, 95% CI 0.48-0.77, derived standardized mean difference (SMD) 0.45, 95% CI -0.07 to 1.04, derived OR 2.1, 95% CI 0.89-5.95), the per-protocol analysis showed a statistical significant superiority of Cerebrolysin (pWei-Lachin = 0.0240, MWcombined = 0.69, 95% CI 0.53 to 0.85, derived SMD 0.69, 95% CI 0.09 to 1.47, derived OR 3.2, 95% CI 1.16 to 12.8), with effect sizes of six single outcomes lying above the benchmark for "large" superiority. Safety aspects were comparable to placebo. CONCLUSION Our trial suggests beneficial effects of Cerebrolysin on outcome after TBI. Results should be confirmed by a larger RCT with a comparable multidimensional approach.

Abstract
OBJECTIVES Estimate the inter-rater reliability of critical care nurses performing a pediatric modification of the Glasgow Coma Scale in a contemporary PICU. DESIGN Prospective observation study. SETTING Large academic PICU. PATIENTS/SUBJECTS All 274 nurses with permanent assignments in the PICU were eligible to participate. A subset of 18 nurses were selected as study registered nurses. All PICU patients were eligible to participate. INTERVENTIONS None. MEASUREMENTS AND MAIN RESULTS PICU nurses were educated and demonstrated proficiency on a pediatric modification of the Glasgow Coma Scale we created to make it more applicable to a diverse PICU population that included patients who are sedated, mechanically ventilated, and/or have developmental disabilities. Each study registered nurse observed a sample of nurses perform the Glasgow Coma Scale, and they independently scored the Glasgow Coma Scale. Patients were categorized as having developmental disabilities if their preillness Pediatric Cerebral Performance Category score was greater than or equal to 3. Fleiss' Kappa (κ), intraclass correlation coefficient, and percent agreement assessed inter-rater reliability for each Glasgow Coma Scale component (eye, verbal, motor) and age-specific scale (≥ 2 and < 2-yr-old). The overall percent agreement between study registered nurses and nurses was 89% for the eye, 91% for the verbal, and 79% for the motor responses. Inter-rater reliability ranged from good (intraclass correlation coefficient = 0.75) to excellent (intraclass correlation coefficient = 0.96) for testable patients. Agreement on the motor response was significantly lower for children with developmental disabilities (< 2 yr: 59% vs 95%; p = 0.0012 and ≥ 2 yr: 55% vs 91%; p = 0.0012). Agreement was significantly worse for intermediate range Glasgow Coma Scale motor responses compared with responses at the extremes (e.g., motor responses 2, 3, 4 vs 1, 5, 6; p < 0.05). CONCLUSIONS A pediatric modification of the Glasgow Coma Scale performed by trained PICU nurses has excellent inter-rater reliability, although reliability was reduced in patients with developmental disabilities and for intermediate range Glasgow Coma Scale responses. Further research is needed to determine the effectiveness of this Glasgow Coma Scale modification to detect clinical deterioration.

[PMID: 30686543 DOI: 10.1016/j.injury.2019.01.027] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 09/24/2018] [Revised: 01/02/2019] [Accepted: 01/14/2019] [Indexed: 02/02/2023]
Abstract
BACKGROUND Most trauma mortality prediction scores are complex in nature. GAP (Glasgow Coma Scale, Age, Systolic blood pressure) and mGAP (mechanism, Glasgow Coma Scale, Age, Systolic blood pressure) scores are relatively simple scoring tools. However, these scores were not validated in low and middle income countries including Malaysia and its accuracies are influenced by the fluctuating physiologic parameters. This study aims to develop a relevant simplified anatomic trauma scoring system for the local trauma patients in Malaysia. METHOD A total of 3825 trauma patients from 2011 to 2016 were extracted from the Hospital Sultanah Aminah Trauma Surgery Registry. Patients were split into a development sample (n = 2683) and a validation sample (n = 1142). Univariate analysis is applied to identify significant anatomic predictors. These predictors were further analyzed using multivariable logistic regression to develop the new score and compared to existing score systems. The quality of prediction was determined regarding discrimination using sensitivity, specificity and receiver operating characteristic [ROC] curve. RESULTS Existing simplified score systems (GAP & mGAP) revealed areas under the ROC curve of 0.825 and 0.806. The newly developed HeCLLiP (Head, cervical spine, lung, liver, pelvic fracture) score combines only five anatomic components: injury involving head, cervical spine, lung, liver and pelvic bone. The probabilities of mortality can be estimated by charting the total score points onto a graph chart or using the cut-off value of (>2) with a sensitivity of 79.2 and specificity of 70.6% on the validation dataset. The HeCLLiP score achieved comparable values of 0.802 for the area under the ROC curve in validation samples. CONCLUSION HeCLLiP Score is a simplified anatomic score suited to the local Malaysian population with a good predictive ability for trauma mortality.

Does an assessment aid improve Glasgow Coma Scale scoring by helicopter rescuers in Hong Kong: A randomised controlled trial. Australas Emerg Care 2019; 21:105-110. [PMID: 30998881 DOI: 10.1016/j.auec.2018.06.001] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/23/2018] [Revised: 05/15/2018] [Accepted: 06/01/2018] [Indexed: 11/22/2022]
Abstract
BACKGROUND Glasgow Coma Scale (GCS) is one of the most commonly used patient assessment tools. This study aimed to determine whether an assessment aid can improve the GCS scoring accuracy by helicopter rescuers in Hong Kong. METHODS In this randomised controlled trial, Air Crewman Officers (ACMOs) of Government Flying Service in Hong Kong were randomised into two groups, with and without assessment aid. The group with the assessment aid was provided a printed copy of the GCS scoring table while watching the patient simulated videos. Ten videos with GCS scores ranging from 3 to 15 were used to test the performance of total GCS (tGCS) and motor component of GCS (mGCS) scoring. RESULTS 78% (n=25/32) of ACMOs participated in the study. By comparing the groups with and without an assessment aid, there was no significant difference in the accuracy of tGCS score (60% versus 60%; p=0.85) or mGCS score (80% versus 80%; p=0.75). Overall, mGCS has a higher accuracy than tGCS (p<0.001). The accuracy of mGCS was better than tGCS in mild and moderate brain injury scenarios. CONCLUSION The use of an assessment aid did not improve GCS scoring by helicopter rescuers. The assessing of mGCS was more accurate than tGCS, further supporting the use of mGCS for prehospital conscious level assessment.

Abstract
Secondary injuries are associated with bad outcomes in the case of severe traumatic brain injury (sTBI). Patients with a Glasgow Coma Scale (GCS) < 9 should undergo pre-hospital intubation (PHI). There is controversy about whether PHI is beneficial. The aim of this study was to estimate the effect of PHI in patients after sTBI. A multicenter, prospective cohort study was performed in Switzerland, including 832 adults with sTBI. Outcomes were death and impaired consciousness at 14 days. Associations between risk factors and outcomes were assessed with univariate and multivariate Cox models for survival, and univariate and multivariate regression models for impaired consciousness. Potential risk factors were age, GCS on scene, pupil reaction, Injury Severity Score (ISS), PHI, oxygen administration, and type of admission to trauma center. Age, GCS on scene < 9, abnormal pupil reaction and ISS ≥ 25 were associated with mortality. GCS < 9 and ISS ≥ 25 were correlated with impaired consciousness. PHI was overall not associated with short-term mortality and consciousness. However, there was a significative interaction with PHI and major trauma. PHI improves outcome from patients with sTBI and an ISS ≥ 25.

Abstract
Timing of the intervention for intracranial hematomas is critical for its success, specifically since expansion of the hemorrhage can result in debilitating and sometimes fatal outcomes. Led by Britton Chance, we and an extended team from University of Pennsylvania, Baylor and Drexel universities developed a handheld brain hematoma detector for early triage and diagnosis of head trauma victims. After obtaining de novo Food and Drug Administration clearance, over 200 systems are deployed in all Marine battalion aid stations around the world. Infrascanner, a handheld brain hematoma detection system, is based on the differential near-infrared light absorption of the injured versus the noninjured part of brain. About 12 independent studies have been conducted in the USA, Canada, Spain, Italy, the Netherlands, Germany, Russia, Poland, Afghanistan, India, China, and Turkey. Here, we outline the background and design of the device as well as clinical studies with a total of 1293 patients and 203 hematomas. Infrascanner demonstrates high sensitivity (adults: 92.5% and children: 93%) and specificity (adults: 82.9% and children: 86.5%) in detecting intracranial hematomas >3.5 mL in volume and <2.5 cm from the surface of the brain. Infrascanner is a clinically effective screening solution for head trauma patients in prehospital settings where timely triage is critical.

Abstract
Traumatic brain injury (TBI) is a major healthcare problem and a major burden to society. The identification of a TBI can be challenging in the prehospital setting, particularly in elderly patients with unobserved falls. Errors in triage on scene cannot be ruled out based on limited clinical diagnostics. Potential new mobile diagnostics may decrease these errors. Prehospital care includes decision-making in clinical pathways, means of transport, and the degree of prehospital treatment. Emergency care at hospital admission includes the definitive diagnosis of TBI with, or without extracranial lesions, and triage to the appropriate receiving structure for definitive care. Early risk factors for an unfavorable outcome includes the severity of TBI, pupil reaction and age. These three variables are core variables, included in most predictive models for TBI, to predict short-term mortality. Additional early risk factors of mortality after severe TBI are hypotension and hypothermia. The extent and duration of these two risk factors may be decreased with optimal prehospital and emergency care. Potential new avenues of treatment are the early use of drugs with the capacity to decrease bleeding, and brain edema after TBI. There are still many uncertainties in prehospital and emergency care for TBI patients related to the complexity of TBI patterns.

Comparison of two simple models for prediction of short term mortality in patients after severe traumatic brain injury. Injury 2019; 50:65-72. [PMID: 30213562 DOI: 10.1016/j.injury.2018.08.022] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 04/23/2018] [Revised: 08/06/2018] [Accepted: 08/23/2018] [Indexed: 02/02/2023]
Abstract
INTRODUCTION The subscale motor score of Glasgow Coma Scale (msGCS) and the Abbreviated Injury Score of head region (HAIS) are validated prognostic factors in traumatic brain injury (TBI). The aim was to compare the prognostic performance of a HAIS-based prediction model including HAIS, pupil reactivity and age, and the reference prediction model including msGCS in emergency department (ED), pupil reactivity and age. METHODS Secondary analysis of a prospective epidemiological study including patients after severe TBI (HAIS > 3) with follow-up from the time of accident until 14 days or earlier death was performed in Switzerland. Performance of prediction, based on accuracy of discrimination [area under the receiver-operating curve (AUROC)], calibration (Hosmer-Lemeshow test) and validity (bootstrapping with 2000 repetitions to correct) for optimism of the two prediction models were investigated. A non-inferiority approach was performed and an a priori threshold for important differences was established. RESULTS The cohort included 808 patients [median age 56 {inter-quartile range (IQR) 33-71}, median motor part of GCS in ED 1 (1-6), abnormal pupil reactivity 29.0%] with a death rate of 29.7% at 14 days. The accuracy of discrimination was similar (AUROC HAIS-based prediction model: 0.839; AUROC msGCS-based prediction model: 0.826, difference of the 2 AUROC 0.013 (-0.007 to 0.037). A similar calibration was observed (Hosmer-Lemeshow X2 11.64, p = 0.168 vs. Hosmer-Lemeshow X2 8.66, p = 0.372). Internal validity of HAIS-based prediction model was high (optimism corrected AUROC: 0.837). CONCLUSIONS Performance of prediction for short-term mortality after severe TBI with HAIS-based prediction model was non-inferior to reference prediction model using msGCS as predictor.

Abstract
BACKGROUND The primary aim was to investigate the performance of a National Advisory Committee for Aeronautics based predictive model (NACA-BM) for mortality at 14 days and a reference model using motor GCS (GCS-RM). The secondary aim was to compare the models for impaired consciousness of survivors at 14 days (IC-14; GCS ≤ 13). METHODS Patients ≥16 years having sustained TBI with an abbreviated injury scale score of head region (HAIS) of >3 were included. Multivariate logistic regression models were used to test models for death and IC-14. The discrimination was assessed using area under the receiver-operating curves (AUROCs); noninferiority margin was -5% between the AUROCs. Calibration was assessed using the Hosmer Lemeshow goodness-of-fit test. RESULTS Six hundred and seventy seven patients were included. The median age was 54 (IQR 32-71). The mortality rate was 31.6%; 99 of 438 surviving patients (22.6%) had an IC-14. Discrimination of mortality was 0.835 (95%CI 0.803-0.867) for the NACA-BM and 0.839 (0.807-0.872) for the GCS-RM; the difference of the discriminative ability was -0.4% (-2.3% to +1.7%). Calibration was appropriate for the NACA-BM (χ2 8.42; P = 0. 393) and for the GCS-RM (χ2 3.90; P = 0. 866). Discrimination of IC-14 was 0.757 (0.706-0.808) for the NACA-BM and 0.784 (0.734-0.835) for the GCS-RM; the difference of the discriminative ability was -2.5% (-7.8% to +2.6%). Calibration was appropriate for the NACA-BM (χ2 10.61; P = 0.225) and for the GCS-RM (χ2 6.26; P = 0.618). CONCLUSIONS Prehospital prediction of mortality after TBI was good with both models, and the NACA-BM was not inferior to the GCS-RM. Prediction of IC-14 was moderate in both models.

Abstract
IntroductionNeurodevelopmental disabilities in children with CHD can result from neurologic injury sustained in the cardiac ICU when children are at high risk of acute neurologic injury. Physicians typically order and specify frequency for serial bedside nursing clinical neurologic assessments to evaluate patients' neurologic status.Materials and methodsWe surveyed cardiac ICU physicians to understand how these assessments are performed, and the attitudes of physicians on the utility of these assessments. The survey contained questions regarding assessment elements, assessment frequency, communication of neurologic status changes, and optimisation of assessments. RESULTS: Surveys were received from 50 institutions, with a response rate of 86%. Routine clinical neurologic assessments were reported to be performed in 94% of institutions and standardised in 56%. Pupillary reflex was the most commonly reported assessment. In all, 77% of institutions used a coma scale, with Glasgow Coma Scale being most common. For patients with acute brain injury, 82% of institutions reported performing assessments hourly, whereas assessment frequency was more variable for low-risk and high-risk patients without overt brain injury. In all, 84% of respondents thought their current practice for assessing and monitoring neurologic status was suboptimal. Only 41% felt that the Glasgow Coma Scale was a valuable tool for assessing neurologic function in the cardiac ICU, and 91% felt that a standardised approach to assessing pre-illness neurologic function would be valuable. CONCLUSIONS: Routine nursing neurologic assessments are conducted in most surveyed paediatric cardiac ICUs, although assessment characteristics vary greatly between institutions. Most clinicians rated current neurologic assessment practices as suboptimal.

Abstract
OBJECTIVE To evaluate utility and equivalence of Glasgow Coma Scale (GCS) and the Alert, Voice, Pain, Unresponsive (AVPU) scale in children with head injury. DESIGN Cross sectional study. SETTING UK hospital admissions: September 2009-February 2010. PATIENTS <15 years with head injury. INTERVENTIONS GCS and/or AVPU at injury scene and in emergency departments (ED). MAIN OUTCOME Measures used, the equivalence of AVPU to GCS, GCS at the scene predicting GCS in ED, CT results by age, hospital type. RESULTS Level of consciousness was recorded in 91% (5168/5700) in ED (43%: GCS/30.5%: GCS+AVPU/17.3%: AVPU) and 66.1% (1190/1801) prehospital (33%: GCS/26%GCS+AVPU/7%: AVPU). Failure to record level of consciousness and the use of AVPU were greatest for infants. Correlation between AVPU and median GCS in 1147 children <5 years: A=15, V=14, P=8, U=3, for 1163 children ≥5 years: A=15, V=13, P=11, U=3. There was no significant difference in the proportion of infants who had a CT whether AVPU=V/P/U or GCS<15. However diagnostic yield of intracranial injury or depressed fracture was significantly greater for V/P/U than GCS<15 :7/7: 100% (95% CI 64.6% to 100%) versus 5/17: 29.4% (95% CI 13.3% to 53.1%). For children >1 year significantly more had a CT scan when GCS<14 was recorded than 'V/P/U only' and the diagnostic yield was greater. Prehospital GCS and GCS in the ED were the same for 77.4% (705/911). CONCLUSION There was a clear correlation between Alert and GCS=15 and between Unresponsive and GCS=3 but a wider range of GCS scores for responsive to Pain or Voice that varied with age. AVPU was valuable at initial assessment of infants and did not adversely affect the proportion of infants who had head CT or the diagnostic yield.

Abstract
BACKGROUND Discordant assessments of Glasgow Coma Score (GCS) following trauma can result in inappropriate triage. This study sought to determine the reliability of prehospital GCS compared to emergency department (ED) GCS. METHODS We conducted a retrospective review of traumas from 01/2000 to 12/2015 at a Level-1 pediatric trauma center. We evaluated reliability between field and ED GCS using Pearson's correlation. We ascertained the difference between prehospital and ED GCS (delta-GCS). Associations between patient characteristics and delta-GCS were modeled using Poisson and linear regression, adjusting for demographic and clinical covariates. RESULTS We identified 5306 patients. Pearson's correlation for GCS measurements was 0.57 for ages 0-3, and 0.67-0.77 for other age groups. Mean delta-GCS was highest for age<3years (0.95, SD=2.4). Poisson regression demonstrated that compared to children 0-3years, higher age was associated with lower delta-GCS (RR 0.65 95% CI 0.56-0.74). Linear regression showed that in those with a delta-GCS, more severe injury (higher ISS, worse ED disposition) and older age were associated with a negative change, signifying decline in score. CONCLUSIONS GCS is generally unreliable in pediatric trauma patients aged 0-3years, particularly the verbal score component. This may impact accuracy of triage priority for pediatric trauma patients.

Abstract
OBJECTIVE To investigate whether emotional intelligence (EI) skills measured via the Perceiving, Understanding, and Managing Emotions branches of the Mayer-Salovey-Caruso Emotional Intelligence Test V2.0 are associated with community integration (CI) and return to work (RTW) after moderate-to-severe acquired brain injury (ABI), after accounting for other established predictors. DESIGN Retrospective cohort study. SETTING Outpatient follow-up services within 2 specialist ABI rehabilitation centers in Melbourne, Australia. PARTICIPANTS Individuals (N=82) with moderate-to-severe ABI discharged from inpatient rehabilitation and living in the community (2mo to 7y postinjury). INTERVENTION Not applicable. MAIN OUTCOME MEASURES Community Integration Questionnaire scores for the total sample (N=82; age range 18-80) and RTW status (employed vs not employed) for the subset of participants employed prior to ABI (n=71; age range 19-66). RESULTS Hierarchical logistic and multiple regression analyses were used to examine the unique contribution of Perceiving, Understanding, and Managing Emotions scores to RTW and CI, after controlling for demographic, injury-related, psychological, and cognitive predictors. As a set, the 3 EI variables did not explain incremental variance in outcomes. However, individually, Understanding Emotions predicted RTW (adjusted odds ratio=3.10, P=.03), χ2 (12)=35.52, P<.001, and Managing Emotions predicted CI (β=0.23, P=.036), F12,69=5.14, P<.001. CONCLUSION Although the EI constructs in combination did not improve prediction beyond the effects of established variables, individual components of strategic EI may be important for specific participation outcomes after ABI.

Prospective evaluation of the Quality of Life after Brain Injury (QOLIBRI) score: minor differences in patients with major versus no or mild traumatic brain injury at one-year follow up. Health Qual Life Outcomes 2018; 16:136. [PMID: 29986710 PMCID: PMC6038178 DOI: 10.1186/s12955-018-0966-z] [Citation(s) in RCA: 11] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/10/2018] [Accepted: 07/02/2018] [Indexed: 02/02/2023] Open
Abstract
Background The Quality of Life after Brain Injury (QOLIBRI) score was developed to assess disease-specific health-related quality of life (HRQoL) after traumatic brain injury (TBI). So far, validation studies on the QOLIBRI were only conducted in cohorts with traumatic brain injury. This study investigated the longer-term residuals in severely injured patients, focusing specifically on the possible impact of major TBI. Methods In a prospective questionnaire investigation, 199 survivors with an injury severity score (ISS) > 15 participated in one-year follow-up. Patients who had sustained major TBI (abbreviated injury scale, AIS head > 2) were compared with patients who had no or only mild TBI (AIS head ≤ 2). Univariate analysis (ANOVA, Cohen’s kappa, Pearson’s r) and stepwise linear regression analysis (B with 95% CI, R, R2) were used. Results The total QOLIBRI revealed no differences in one-year outcomes between patients with versus without major TBI (75 and 76, resp.; p = 0.68). With regard to the cognitive subscore, the group with major TBI demonstrated significantly more limitations than the one with no or mild TBI (p < 0.05). The AIS head correlated significantly with the cognitive dimension of the QOLIBRI (r = − 0.16; p < 0.05), but not with the mental components of the SF-36 or the TOP. In multivariate analysis, the influence of the severity of head injury (AIS head) on total QOLIBRI was weaker than that of injured extremities (R2 = 0.02; p < 0.05 vs. R2 = 0.04; p = 0.001) and equal to the QOLIBRI cognitive subscore (R2 = 0.03, p < 0.01 each). Conclusions Given the unexpected result of similar mean QOLIBRI total score values and only minor differences in cognitive deficits following major trauma independently of whether patients sustained major brain injury or not, further studies should investigate whether the QOLIBRI actually has the discriminative capacity to detect specific residuals of major TBI. In effect, the score appears to indicate mental deficits following different types of severe trauma, which should be evaluated in more detail. Trial registration NCT02165137; retrospectively registered 11 June 2014.

Abstract
BACKGROUND The Glasgow Coma Scale (GCS) characterizes patients with diminished consciousness. In a recent systematic review, we found overall adequate reliability across different clinical settings, but reliability estimates varied considerably between studies, and methodological quality of studies was overall poor. Identifying and understanding factors that can affect its reliability is important, in order to promote high standards for clinical use of the GCS. OBJECTIVE The aim of this systematic review was to identify factors that influence reliability and to provide an evidence base for promoting consistent and reliable application of the GCS. METHODS A comprehensive literature search was undertaken in MEDLINE, EMBASE, and CINAHL from 1974 to July 2016. Studies assessing the reliability of the GCS in adults or describing any factor that influences reliability were included. Two reviewers independently screened citations, selected full texts, and undertook data extraction and critical appraisal. Methodological quality of studies was evaluated with the consensus-based standards for the selection of health measurement instruments checklist. Data were synthesized narratively and presented in tables. RESULTS Forty-one studies were included for analysis. Factors identified that may influence reliability are education and training, the level of consciousness, and type of stimuli used. Conflicting results were found for experience of the observer, the pathology causing the reduced consciousness, and intubation/sedation. No clear influence was found for the professional background of observers. CONCLUSION Reliability of the GCS is influenced by multiple factors and as such is context dependent. This review points to the potential for improvement from training and education and standardization of assessment methods, for which recommendations are presented.

Abstract
Accurate assessment of the acutely ill adult who has recently been admitted to hospital, or an inpatient whose condition begins to deteriorate, is becoming a required skill for nurses as people live longer and with a variety of complex conditions, and as nursing skills continue to evolve and develop. This article emphasises the importance of undertaking an accurate and comprehensive patient assessment to ensure that management strategies are implemented in a timely manner. The article also considers the importance of the National Early Warning Score (NEWS), which is a 'track-and-trigger' tool designed to identify patients who are at risk of deterioration. The presentation of shock is considered and how this can be identified using the NEWS. The patient assessment skills required by nurses are discussed and the main signs of patient deterioration, regardless of cause, are outlined. The article also examines the ABCDE (airway, breathing, circulation, disability and exposure) approach to assessment.

Evaluation of novel computerized tomography scoring systems in human traumatic brain injury: An observational, multicenter study. PLoS Med 2017; 14:e1002368.

Abstract
BACKGROUND Traumatic brain injury (TBI) is a major contributor to morbidity and mortality. Computerized tomography (CT) scanning of the brain is essential for diagnostic screening of intracranial injuries in need of neurosurgical intervention, but may also provide information concerning patient prognosis and enable baseline risk stratification in clinical trials. Novel CT scoring systems have been developed to improve current prognostic models, including the Stockholm and Helsinki CT scores, but so far have not been extensively validated. The primary aim of this study was to evaluate the Stockholm and Helsinki CT scores for predicting functional outcome, in comparison with the Rotterdam CT score and Marshall CT classification. The secondary aims were to assess which individual components of the CT scores best predict outcome and what additional prognostic value the CT scoring systems contribute to a clinical prognostic model. METHODS AND FINDINGS TBI patients requiring neuro-intensive care and not included in the initial creation of the Stockholm and Helsinki CT scoring systems were retrospectively included from prospectively collected data at the Karolinska University Hospital (n = 720 from 1 January 2005 to 31 December 2014) and Helsinki University Hospital (n = 395 from 1 January 2013 to 31 December 2014), totaling 1,115 patients. The Marshall CT classification and the Rotterdam, Stockholm, and Helsinki CT scores were assessed using the admission CT scans. Known outcome predictors at admission were acquired (age, pupil responsiveness, admission Glasgow Coma Scale, glucose level, and hemoglobin level) and used in univariate, and multivariable, regression models to predict long-term functional outcome (dichotomizations of the Glasgow Outcome Scale [GOS]). In total, 478 patients (43%) had an unfavorable outcome (GOS 1-3). In the combined cohort, overall prognostic performance was more accurate for the Stockholm CT score (Nagelkerke's pseudo-R2 range 0.24-0.28) and the Helsinki CT score (0.18-0.22) than for the Rotterdam CT score (0.13-0.15) and Marshall CT classification (0.03-0.05). Moreover, the Stockholm and Helsinki CT scores added the most independent prognostic value in the presence of other known clinical outcome predictors in TBI (6% and 4%, respectively). The aggregate traumatic subarachnoid hemorrhage (tSAH) component of the Stockholm CT score was the strongest predictor of unfavorable outcome. The main limitations were the retrospective nature of the study, missing patient information, and the varying follow-up time between the centers. CONCLUSIONS The Stockholm and Helsinki CT scores provide more information on the damage sustained, and give a more accurate outcome prediction, than earlier classification systems. The strong independent predictive value of tSAH may reflect an underrated component of TBI pathophysiology. A change to these newer CT scoring systems may be warranted.

Abstract
The Glasgow Coma Scale (GCS) and the Abbreviated Injury Score of the head region (HAIS) are validated prognostic factors in traumatic brain injury (TBI). The aim of this study was to compare the prognostic performance of an alternative predictive model including motor GCS, pupillary reactivity, age, HAIS, and presence of multi-trauma for short-term mortality with a reference predictive model including motor GCS, pupil reaction, and age (IMPACT core model). A secondary analysis of a prospective epidemiological cohort study in Switzerland including patients after severe TBI (HAIS >3) with the outcome death at 14 days was performed. Performance of prediction, accuracy of discrimination (area under the receiver operating characteristic curve [AUROC]), calibration, and validity of the two predictive models were investigated. The cohort included 808 patients (median age, 56; interquartile range, 33-71), median GCS at hospital admission 3 (3-14), abnormal pupil reaction 29%, with a death rate of 29.7% at 14 days. The alternative predictive model had a higher accuracy of discrimination to predict death at 14 days than the reference predictive model (AUROC 0.852, 95% confidence interval [CI] 0.824-0.880 vs. AUROC 0.826, 95% CI 0.795-0.857; p < 0.0001). The alternative predictive model had an equivalent calibration, compared with the reference predictive model Hosmer-Lemeshow p values (Chi2 8.52, Hosmer-Lemeshow p = 0.345 vs. Chi2 8.66, Hosmer-Lemeshow p = 0.372). The optimism-corrected value of AUROC for the alternative predictive model was 0.845. After severe TBI, a higher performance of prediction for short-term mortality was observed with the alternative predictive model, compared with the reference predictive model.
