The frequency of pressure injury in level 3 intensive care units and determination of risk factors: A cross-sectional study.

AIM: This study was carried out to determine the prevalence of pressure injury and risk factors in patients hospitalized in a university hospital's level 3 intensive care unit. DESIGN: It is a descriptive, prospective, observational type study. METHOD: The sample of the study consisted of 176 patients aged 18 and over who were admitted to the intensive care units of a University Hospital for at least 24 h. Patient Information Form and Braden Risk Assessment Scale, Glasgow Coma Scale were used to collect data. IBM SPSS Statistics 20 program was used to analyze the data. RESULTS: Presence of chronic disease in the development of pressure injury (22.7%), high-risk patients according to the Glasgow Coma Scale (21%), high-risk patients according to the Braden Risk Assessment Scale (84.2%), low hemoglobin (31%), low albumin levels (32.4%) and duration of stay in the intensive care unit until the day of evaluation were found to be independent risk factors (p < 0.05). The prevalence of pressure injury was determined to be 32.4%, and the rate of pressure injury due to medical devices was 7.4%. CONCLUSION: Pressure injuries are still common in adult intensive care patients. In terms of patient safety, it is important to give more space to care standards and awareness-raising research and training to prevent pressure injuries.

An Assessment of Clinical Accuracy of Vital Sign-based Triage Tools Among U.S. and Coalition Forces.

INTRODUCTION: Early appropriate allocation of resources for critically injured combat casualties is essential. This is especially important when inundated with an overwhelming number of casualties where limited resources must be efficiently allocated, such as during mass casualty events. There are multiple scoring systems utilized in the prehospital combat setting, including the shock index (SI), modified shock index (MSI), simple triage and rapid treatment (START), revised trauma score (RTS), new trauma score (NTS), Glasgow Coma Scale + age + pressure (GAP), and the mechanism + GAP (MGAP) score. The optimal score for application to the combat trauma population remains unclear. MATERIALS AND METHODS: This is a secondary analysis of a previously described dataset from the Department of Defense Trauma Registry from January 1, 2007 through March 17, 2020. We constructed univariable analyses to determine the area under the receiving operator characteristic (AUROC) for the scoring systems of interest. Our primary outcomes were early death (within 24 hours) or early massive transfusion, as defined by ≥3 units. RESULTS: There were 12,268 casualties that met inclusion criteria. There were 168 (1%) who died within the first 24 hours and 2082 (17%) that underwent significant transfusion within the first 24 hours. When assessing the predictive capabilities for death within 24 hours, the AUROCs were 0.72 (SI), 0.69 (MSI), 0.89 (START), 0.90 (RTS), 0.83 (NTS), 0.90 (GAP), and 0.91 (MGAP). The AUROCs for massive transfusion were 0.89 (SI), 0.89 (MSI), 0.82 (START), 0.81 (RTS), 0.83 (NTS), 0.85 (MGAP), and 0.86 (GAP). CONCLUSIONS: This study retrospectively applied seven triage tools to a database of 12,268 cases from the Department of Defense Trauma Registry to evaluate their performance in predicting early death or massive transfusion in combat. All scoring systems performed well with an AUROC >0.8 for both outcomes. Although the SI and MSI performed best for predicting massive transfusion (both had an AUROC of 0.89), they ranked last for assessment of mortality within 24 hours, with the other tools performing well. START, RTS, NTS, MGAP and GAP reliably identified early death and need for massive transfusion, with MGAP and GAP performing the best overall. These findings highlight the importance of assessing triage tools to best manage resources and ultimately preserve lives of traumatically wounded warfighters. Further studies are needed to explain the surprising performance discrepancy of the SI and MSI in predicting early death and massive transfusion.

Admission pattern, treatment outcomes, and associated factors for children admitted to pediatric intensive care unit of Tikur Anbessa specialized hospital, 2021: a retrospective cross-sectional study.

BACKGROUND: Assessement of the pattern of admission and treatment outcomes of critically ill pediatrics admitted to pediatric intensive care units (PICU) in developing countries is crucial. In these countries with resource limitations, it may help to identify priorities for resource mobilization that may improve patient service quality. The PICU mortality rate varies globally, depending on the facilities of the intensive care unit, availability of experties, and admission patterns. This study assessed the admission pattern, treatment outcomes, and associated factors for children admitted to the PICU. METHODS: A retrospective cross-sectional study was implemented on 406 randomly selected pediatrics patients admitted to the PICU of Tikur Anbessa Specialized Hospital from 1-Oct-2018 to 30-Sept-2020. The data were collected with a pretested questionnaire. A normality curve was used to check for data the distribution. Both bivariable and multivariable analyses were used to see association of variables. A variable with a p-value of < 0.2 in the bivariable model was a candidate for multivariate analysis. The strength of association was shown by an adjusted odds ratio (AOR) with a 95% Confidence interval (CI), and a p-value of < 0.05 was considered statistically significant. Frequency, percentage,and tables were used to present the data. RESULTS: A total of 361 (89% response rate) patient charts were studied, 197 (54.6%) were male, and 164(45.4%) were female. The most common pattern for admission was a septic shock (27.14%), whereas the least common pattern was Asthma 9(2.50%). The mortality rate at the pediatric intensive care unit was 43.8%. Moreover, mechanical ventilation need (AOR = 11.2, 95%CI (4.3-28.9), P < 0.001), need for inotropic agents (AOR = 10.7, 95%CI (4.1-27.8), P < 0.001), comorbidity (AOR =8.4, 95%CI (3.5-20.5), P < 0.001), length of PICU stay from 2 to 7 days (AOR = 7.3, 95%CI (1.7-30.6), P = 0.007) and severe GCS (< 8) (AOR = 10.5, 95%CI (3.8-29.1), P < 0.001) were independent clinical outcome predictors (mortality). CONCLUSION: The mortality rate at the PICU was 43.8%. Septic shock, and meningitis were the common cause of death and the largest death has happened in less than 7 days of admission.

Epidemiological changes of geriatric trauma in the United Arab Emirates.

ABSTRACT: We aimed to study the epidemiological changes in geriatric trauma in Al-Ain City, United Arab Emirates, in the past decade to give recommendations on injury prevention.Trauma patients aged 65 years and above who were hospitalized at Al-Ain Hospital for more than 24 hours or died in the hospital after their arrival regardless of the length of stay were studied. Data were extracted from the Al-Ain Hospital trauma registry. Two periods were compared; March 2003 to March 2006 and January 2014 to December 2017. Studied variables which were compared included demography, mechanism of injury and its location, and clinical outcome.There were 66 patients in the first period and 200 patients in the second period. The estimated annual incidence of hospitalized geriatric trauma patients in Al-Ain City was 8.5 per 1000 geriatric inhabitants in the first period compared with 7.8 per 1000 geriatric inhabitants in the second period. Furthermore, mortality was reduced from 7.6% to 2% (P = 0.04). There was a significant increase in falls on the same level by14.9% (62.1%-77%, P = 0.02, Pearson χ2 test). This was associated with a significant increase of injuries occurring at home (55.4%-78.7% P = 0.0003, Fisher Exact test). There was also a strong trend in the reduction of road traffic collision injuries which was reduced by 10.8% (27.3%-16.5%, P = 0.07, Fisher Exact test).Although the incidence and severity of geriatric trauma did not change over the last decade, in-hospital mortality has significantly decreased over time. There was a significant increase in injuries occurring at homes and in falls on the same level. The home environment should be targeted in injury prevention programs so as to reduce geriatric injuries.

Limits of the Glasgow Coma Scale When Assessing for Sepsis in Allogeneic Hematopoietic Cell Transplant Recipients.

BACKGROUND: The well-documented association between acute mental status changes and sepsis development and progression makes acute mental status an attractive factor for sepsis screening tools. However, the usefulness of acute mental status within these criteria is limited to the frequency and accuracy of its capture. The Glasgow Coma Scale (GCS) score-the acute mental status indicator in many clinical sepsis criteria-is infrequently captured among allogeneic hematopoietic cell transplant recipients with suspected infections, and its ability to serve as an indicator of acute mental status among this high-risk population is unknown. OBJECTIVE: We evaluated the GCS score as an indicator of acute mental status during the 24 hours after suspected infection onset among allogeneic hematopoietic cell transplant recipients. METHODS: Using data from the first 100 days posttransplant for patients transplanted at a single center between September 2010 and July 2017, we evaluated the GCS score as an indicator of documented acute mental status during the 24 hours after suspected infection onset. From all inpatients with suspected infections, we randomly selected a cohort based on previously published estimates of GCS score frequency among hematopoietic cell transplant recipients with suspected infections and performed chart review to ascertain documentation of clinical acute mental status within the 24 hours after suspected infection onset. RESULTS: A total of 773 patients had ≥1 suspected infections and experienced 1,655 suspected infections during follow-up-625 of which had an accompanying GCS score. Among the randomly selected cohort of 100 persons with suspected infection, 28 were accompanied with documented acute mental status, including 18 without a recorded GCS. In relation to documented acute mental status, the GCS had moderate to high sensitivity and high specificity. DISCUSSION: These data indicate that, among allogeneic hematopoietic cell transplant recipients with suspected infections, the GCS scores are infrequently collected and have a moderate sensitivity. If sepsis screening tools inclusive of acute mental status changes are to be used, nursing teams need to increase measurement of GCS scores among high sepsis risk patients or identify a standard alternative indicator.

Utility of the Marshall & Rotterdam Classification Scores in Predicting Outcomes in Trauma Patients.

BACKGROUND: Traumatic Brain Injury (TBI) is a leading cause of mortality in the trauma population. Accurate prognosis remains a challenge. Two common Computed Tomography (CT)-based prognostic models include the Marshall Classification and the Rotterdam CT Score. This study aims to determine the utility of the Marshall and Rotterdam scores in predicting mortality for adult patients in coma with severe TBI. METHOD: Retrospective review of our Level 1 Trauma Center's registry for patients ≥ 18 years of age with blunt TBI and a Glasgow Coma Scale (GCS) of 3-5, with no other significant injuries. Admission Head CT was evaluated for the presence of extra-axial blood (SDH, EDH, SAH, IVH), intra-axial blood (contusions, diffuse axonal injury), midline shift and mass effect on basilar cisterns. Rotterdam and Marshall scores were calculated for all patients; subsequently patients were divided into two groups according to their score (< 4, ≥ 4). RESULTS: 106 patients met inclusion criteria; 75.5% were males (n = 80) and 24.5% females (n = 26). The mean age was 52. The odds ratio (OR) of dying from severe TBI for patients in coma with a Rotterdam score of ≥ 4 compared to < 4 was OR = 17 (P < 0.05). The odds of dying from severe TBI for patients in coma with a Marshall score of ≥ 4 versus < 4 was OR = 11 (P < 0.05). CONCLUSION: Higher scores in the Marshall classification and the Rotterdam system are associated with increased odds of mortality in adult patients in come from severe TBI after blunt injury. The results of our study support these scoring systems and revealed that a cutoff score of < 4 was associated with improved survival.

Pediatric adjusted reverse shock index multiplied by Glasgow Coma Scale as a prospective predictor for mortality in pediatric trauma.

INTRODUCTION: Shock index and its pediatric adjusted derivative (pediatric age-adjusted shock index [SIPA]) have demonstrated utility as prospective predictors of mortality in adult and pediatric trauma populations. Although basic vital signs provide promise as triage tools, factors such as neurologic status on arrival have profound implications for trauma-related outcomes. Recently, the reverse shock index multiplied by Glasgow Coma Scale (GCS) score (rSIG) has been validated in adult trauma as a tool combining early markers of physiology and neurologic function to predict mortality. This study sought to compare the performance characteristics of rSIG against SIPA as a prospective predictor of mortality in pediatric war zone injuries. METHODS: Retrospective review of the Department of Defense Trauma Registry, 2008 to 2016, was performed for all patients younger than 18 years with documented vital signs and GCS on initial arrival to the trauma bay. Optimal age-specific cutoff values were derived for rSIG via the Youden index using receiver operating characteristic analyses. Multivariate logistic regression was performed to validate accuracy in predicting early mortality. RESULTS: A total of 2,007 pediatric patients with a median age range of 7 to 12 years, 79% male, average Injury Severity Score of 11.9, and 62.5% sustaining a penetrating injury were included in the analysis. The overall mortality was 7.1%. A total of 874 (43.5%) and 685 patients (34.1%) had elevated SIPA and pediatric rSIG scores, respectively. After adjusting for demographics, mechanism of injury, initial vital signs, and presenting laboratory values, rSIG (odds ratio, 4.054; p = 0.01) was found to be superior to SIPA (odds ratio, 2.742; p < 0.01) as an independent predictor of early mortality. CONCLUSION: Reverse shock index multiplied by GCS score more accurately identifies pediatric patients at highest risk of death when compared with SIPA alone, following war zone injuries. These findings may help further refine early risk assessments for patient management and resource allocation in constrained settings. Further validation is necessary to determine applicability to the civilian population. LEVEL OF EVIDENCE: Prognostic study, level IV.

Predictors of Inappropriate Helicopter Transport.

BACKGROUND: Helicopter transport (HT) is an efficient, but costly, means for injured patients to receive life-saving, definitive trauma care. Identifying the characteristics of inappropriate HT presents an opportunity to improve the utilization of this finite medical resource. METHODS: Trauma registry records of all HT for a 3-year period (2016-2018) to an urban Level I trauma center were reviewed. HT was defined as inappropriate for patients who were discharged home from the emergency department or had a hospital length of stay <1 day, and who were discharged alive. Chi-square analysis and Student's t-test were used for univariate analysis. Predictors with a P value of less than .15 were subject to binary logistic regression analysis. A P value ≤.05 was considered significant. RESULTS: There were 713 patients who received HT during the study period. One-hundred and forty-eight (20.8%) patients met the criteria as an inappropriate HT. In univariate analysis, Glasgow Coma Scale >8, Shock Index <0.9, and fall mechanism were found to be significantly associated with inappropriate HT. Age >55 was found to be associated with an appropriate HT. The average Injury Severity Score of the inappropriate HT group was 3.86 (±3.85) compared with 16.80 (±11.23) (P = .0001, Student's t-test). DISCUSSION: Our findings suggest that there are evidence-based predictors of patients receiving inappropriate HT. Triage of HT using these predictors has the potential to decrease unnecessary deployments and reduce health care costs.

Interobserver Reliability of Glasgow Coma Scale Scores for Intensive Care Unit Patients.

BACKGROUND: Intensive care units frequently use the Glasgow Coma Scale to objectively assess patients' levels of consciousness. Interobserver reliability of Glasgow Coma Scale scores is critical in determining the degree of impairment. OBJECTIVE: To evaluate interobserver reliability of intensive care unit patients' Glasgow Coma Scale scores. Methods This prospective observational study evaluated Glasgow Coma Scale scoring agreement among 21 intensive care unit nurses and 2 independent researchers who assessed 202 patients with neurosurgical or neurological diseases. Each assessment was completed independently and within 1 minute. Participants had no knowledge of the others' assessments. RESULTS: Agreement between Glasgow Coma Scale component and sum scores recorded by the 2 researchers ranged from 89.5% to 95.9% (P = .001). Significant agreement among nurses and the 2 researchers was found for eye response (73.8%), motor response (75.0%), verbal response (68.1%), and sum scores (62.4%) (all P = .001). Significant agreement among nurses and the 2 researchers (55.2%) was also found for sum scores of patients with sum scores of 10 or less (P = .03). CONCLUSIONS: Although the study showed near-perfect agreement between the 2 researchers' Glasgow Coma Scale scores, agreement among nurses and the 2 researchers was moderate (not near perfect) for subcomponent and sum scores. Accurate Glasgow Coma Scale evaluation requires that intensive care unit nurses have adequate knowledge and skills. Educational strategies such as simulations or orientation practice with a preceptor nurse can help develop such skills.

Clinical Features and Risk Factors for Mortality in Children With Acute Encephalitis Who Present to the Emergency Department.

Acute encephalitis is an important pediatric emergency that tends to be associated with neurological morbidity, critical illness, and mortality. Few data have specifically focused on evaluating various early clinical parameters in the pediatric emergency department as candidate predictors of mortality. The present retrospective study assessed the clinical, laboratory, and neuroimaging findings of children with acute encephalitis who presented to the emergency department. Of 158 patients diagnosed with encephalitis, 7 (4.4%) had mortality. Compared to the survivors, a multivariate analysis revealed that an initial Glasgow Coma Scale score ≤ 5 (odds ratio [OR]: 8.3, P = .022), acute necrotizing encephalitis (OR: 12.1, P = .01), white blood count level ≤ 5.2 × 109 cells/L (OR: 28.7, P < .001), aspartate aminotransferase level > 35 U/L (OR: 14.3, P = .022), and influenza A infection (OR: 7.7, P = .027) were significantly associated with mortality. These results indicate that the early recognition of preliminary clinical features and the development of more specific etiologies for encephalitis are important for early treatment strategies.

Microsurgery of Cerebral Aneurysm: Epidemiological Profile

Objectives Intracranial aneurysm consists of localized dilatation of the vascular wall. Its importance includes the fearsome event of rupture and subarachnoid hemorrhage, which presents high morbimortality rates. The present study aimed to analyze the profile and clinical outcome of patients submitted to the microsurgical approach of cerebral aneurysm in the city of Criciúma, state of Santa Catarina, Brazil, from 2015 to 2018. Methods A retrospective observational study was performed, with secondary data collection and a quantitative approach of 47 charts. Results A predominance of females (74.5%) and amean age of 53 years old (53.53 9.64) was observed. The middle cerebral artery was the most affected vessel (36.2%), with the highest percentage of aneurysms being between 2.1mmand 7.0mm(65.9%). Therewas a correlation between consciousness level and classification on the Hunt-Hess (HH) scale. Patients with GlasgowComa Scale (GCS)> 7 points had a better prognostic score in the HH scale, and those with GCS 7 points had a worse prognostic score in the HH scale. Conclusions The present study observed the presence of important risk factors for cerebral aneurysm formation, such as gender, age, smoking, and systemic arterial hypertension. The present study can measure a correlation of the level of consciousness with the HH classification.

Role of Xingnaojing Injection in treating acute cerebral hemorrhage: A systematic review and meta-analysis.

BACKGROUND: Xingnaojing injection (XNJi) is widely used for acute cerebral hemorrhage. However, the efficacy of XNJi for acute cerebral hemorrhage has not been comprehensively proved by systematic analysis yet. Therefore, it is essential to evaluate the efficacy and safety of XNJi in an evidence-based method. METHODS: Six databases were searched with XNJi used for acute cerebral hemorrhage in randomized controlled trials (RCTs). Meta-analysis was performed by Review Manager 5.3. The efficacy rate, brain edema, cerebral hematoma, neurological deficit score, hs-crp, Glasgow Coma Scale (GCS), and activities of daily living (ADL) were systematically evaluated. The Cochrane risk of bias was used to evaluate the methodological quality of eligible studies. RESULTS: This study is registered with PROSPERO (CRD42018098737). Twenty-nine studies with a total of 2638 patients were included in this meta-analysis. Compared with conventional treatment, XNJi got higher efficacy rate (OR = 3.37, 95% CI [2.65, 4.28], P < .00001). Moreover, XNJi showed significant enhancement of efficacy rate via subgroup analysis in course and dosage. In addition, XNJi demonstrated significant improvement in Chinese stroke scale (CSS) and National Institutes of Health Stroke Scale (NHISS) (mean difference [MD] = -4.74, 95% CI [-5.89, -3.60], P < .00001; MD = -4.45, 95% CI [-5.49, -3.41], P < .00001), GCS (MD = 2.72, 95% CI [2.09, 3.35], P < .00001). It also remarkably decreased the level of hs-crp (MD = -6.50, 95% CI [-7.79, -5.21], P < .00001), enhanced ADL (MD = 20.38, 95% CI [17.98, 22.79], P < .00001), and alleviated hematoma and edema (MD = -2.53, 95% CI [-4.75, -0.31] P < .05; MD = -1.74 95% CI [-2.42, -1.07] P < .00001) compared with conventional treatment. CONCLUSION: XNJi is effective in treating acute cerebral hemorrhage with significant improvement of CSS, NHISS and impairment of hs-crp, hematoma, and edema compared with conventional treatment. Moreover, XNJi got remarkable efficacy at the dose of 20, 30, 60 mL and from 7 to 28 days. No serious adverse reactions occurred. These results were mainly based on small-sample and low-quality studies. Therefore, more rigorous, large-scale RCTs were further needed to confirm its efficacy, safety, and detailed characteristic of application.

Association of clinically important traumatic brain injury and Glasgow Coma Scale scores in children with head injury.

OBJECTIVE: Head 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. METHODS: Planned 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. RESULTS: Of 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). CONCLUSIONS: Outside 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.

Reverse shock index multiplied by Glasgow Coma Scale (rSIG) predicts mortality in severe trauma patients with head injury.

The reverse shock index (rSI), a ratio of systolic blood pressure (SBP) to heart rate (HR), is used to identify prognosis in trauma patients. Multiplying rSI by Glasgow Coma Scale (rSIG) can possibly predict better in-hospital mortality in patients with trauma. However, rSIG has never been used to evaluate the mortality risk in adult severe trauma patients (Injury Severity Score [ISS] ≥ 16) with head injury (head Abbreviated Injury Scale [AIS] ≥ 2) in the emergency department (ED). This retrospective case control study recruited adult severe trauma patients (ISS ≥ 16) with head injury (head AIS ≥ 2) who presented to the ED of two major trauma centers between January 01, 2014 and May 31, 2017. Demographic data, vital signs, ISS scores, injury mechanisms, laboratory data, managements, and outcomes were included for the analysis. Logistic regression and receiver operating characteristic analysis were used to evaluate the accuracy of rSIG score in predicting in-hospital mortality. In total, 438 patients (mean age: 56.48 years; 68.5% were males) were included in this study. In-hospital mortality occurred in 24.7% patients. The median (interquartile range) ISS score was 20 (17-26). Patients with rSIG ≤ 14 had seven-fold increased risks of mortality than those without rSIG ≤ 14 (odds ratio: 7.64; 95% confidence interval: 4.69-12.42). Hosmer-Lemeshow goodness-of-fit test and area under the curve values for rSIG score were 0.29 and 0.76, respectively. The sensitivity, specificity, positive predictive value, and negative predictive values of rSIG ≤ 14 were 0.71, 0.75, 0.49, and 0.89, respectively. The rSIG score is a prompt and simple tool to predict in-hospital mortality among adult severe trauma patients with head injury.

Coma Reversal After Intravenous Lipid Emulsion Therapy in a Trazodone-Poisoned Patient.

A 77-year-old woman developed a deep coma (Glasgow Coma Scale score at 3/15) after a trazodone overdose (maximal ingested dose, 4500 mg), and orotracheal intubation was required for mechanical ventilation. In addition, she presented sinus bradycardia (<40/min) with QTc prolongation, whereas arterial blood pressure was preserved. The administration of intravenous lipid emulsion (1.5 mL/kg as a bolus followed by a continuous infusion of 0.5 mL/kg per minute for 30 minutes) resulted in a rapid improvement of her neurological condition, with a Glasgow Coma Scale score rising from 3 to 10/15 at the end of intravenous lipid emulsion infusion. A significant increase in heart rate (from 39 to 54/min) was also observed. The treatment was well tolerated, and the patient did not experience ventricular dysrhythmias. In addition, the patient was found to have a reduced metabolic activity related to cytochrome P450 2D6 polymorphism.

The Association of Trauma Center Transport and Long-term Functional Outcomes in Head-injured Older Adults Transported by Emergency Medical Services.

OBJECTIVE: It is unclear whether trauma center care is associated with improved outcomes in older adults with traumatic brain injury (TBI) compared to management at nontrauma centers. Our primary objectives were to describe the long-term outcomes of older adults with TBI and to evaluate the association of trauma center transport with long-term functional outcome. METHODS: This was a prospective, observational study at five emergency medical services (EMS) agencies and 11 hospitals representing all 9-1-1 transfers within a county. Older adults (≥55 years) with TBI (defined as closed head injury associated with loss of consciousness and/or amnesia, abnormal Glasgow Coma Scale [GCS] score, or traumatic intracranial hemorrhage) and transported by EMS from August 2015 to September 2016 were eligible. EMS providers completed standardized data forms and emergency department (ED) and hospital data were abstracted. Functional outcomes were measured using the Extended Glasgow Outcome Scale (GOS-E) at 3- and 6-month intervals by telephone follow-up. Reasons for disabilities were coded as due to head injury, due to illness or injury to other part of body, or due to a mixture of both. To evaluate the association of trauma center transport and functional outcomes, we conducted multivariate ordinal logistic regression analyses on multiple imputed data for 1) all patients with TBI and 2) patients with traumatic intracranial hemorrhage. RESULTS: We enrolled 350 patients with TBI; the median (Q1, Q3) age was 70 (61, 84) years, 187 (53%) were male, and 91 patients (26%) had traumatic intracranial hemorrhage on initial ED cranial computed tomography (CT) imaging. A total of 257 patients (73%) were transported by EMS to a Level I or II trauma center. Sixty-nine patients (20%) did not complete follow-up at 3 or 6 months. Of the patients with follow-up, 119 of 260 patients (46%) had moderate disability or worse at 6 months, including 55 of 260 patients (21%) who were dead at 6-month follow-up. Death or severe disabilities were more commonly attributed to non-TBI causes while moderate disabilities or better were more commonly due to TBI. On adjusted analysis, an abnormal GCS score, higher Charlson Comorbidity Index scores, and the presence of traumatic intracranial hemorrhage on initial ED cranial imaging were associated with worse GOS-E scores at 6 months. Trauma center transport was not associated with GOS-E scores at 6 months for TBI patients and in patients with traumatic intracranial hemorrhage on initial ED CT imaging. CONCLUSIONS: In older adults with TBI, moderate disability or worse is common 6 months after injury. Over one in five of older adults with TBI died by 6 months, usually due to nonhead causes. Patients with TBI or traumatic intracranial hemorrhage did not have improved functional outcomes with initial triage to a trauma center.

Determination of Imminent Brain Death Using the Full Outline of Unresponsiveness Score and the Glasgow Coma Scale: A Prospective, Multicenter, Pilot Feasibility Study.

PURPOSE: To evaluate the accuracy of the imminent brain death (IBD) diagnosis in predicting brain death (BD) by daily assessment of the Full Outline of Unresponsiveness (FOUR) score and the Glasgow Coma Scale (GCS) with the assessment of brain stem reflexes. MATERIALS AND METHODS: Prospective multicenter pilot study carried out in 5 adult Italian intensive care units (ICUs). Imminent brain death was established when the FOUR score was 0 (IBD-FOUR) or the GCS score was 3 and at least 3 among pupillary light, corneal, pharyngeal, carinal, oculovestibular, and trigeminal reflexes were absent (IBD-GCS). RESULTS: A total of 219 neurologic evaluations were performed in 40 patients with deep coma at ICU admission (median GCS 3). Twenty-six had a diagnosis of IBD-FOUR, 27 of IBD-GCS, 14 were declared BD, and 9 were organ donors. The mean interval between IBD diagnosis and BD was 1.7 days (standard deviation [SD] 2.0 days) using IBD-FOUR and 2.0 days (SD 1.96 days) using IBD-GCS. Both FOUR and GCS had 100% sensitivity and low specificity (FOUR: 53.8%; GCS: 50.0%) in predicting BD. CONCLUSIONS: Daily IBD evaluation in the ICU is feasible using FOUR and GCS with the assessment of brain stem reflexes. Both scales had 100% sensitivity in predicting IBD, but FOUR may be preferable since it incorporates the pupillary, corneal, and cough reflexes and spontaneous breathing that are easily assessed in the ICU.

Location-specific differences in hematoma volume predict outcomes in patients with spontaneous intracerebral hemorrhage.

BACKGROUND AND OBJECTIVE: Functional outcome after spontaneous intracerebral hemorrhage (ICH) may vary depending on hematoma volume and location. We assessed the interaction between hematoma volume and location, and modified the original ICH score to include such an interaction. METHODS: Consecutive ICH patients were enrolled in the Intracerebral Hemorrhage Outcomes Project from 2009 to 2017. Inclusion criteria were age≥18 years, baseline modified Rankin Scale (mRS) score 0-2, neuroimaging, and follow-up. Functional dependence and mortality were defined as 90-day mRS>2 and death, respectively. A location ICH score was developed using multivariable regression and area under the receiver operator characteristic curve (AUROC) analyses. RESULTS: The study cohort comprised 311 patients, and the derivation and validation cohorts comprised 209 and 102 patients, respectively. Interactions between hematoma volume and location predicted functional dependence (p = 0.008) and mortality (p = 0.025). The location ICH score comprised age≥80 years (1 point), Glasgow Coma Scale score (3-9 = 2 points; 10-13 = 1 point), volume-location (lobar:≥24 mL=2 points, 21-24 mL=1 point; deep:≥8 mL=2 points, 7-8 mL=1 point; brainstem:≥6 mL=2 points, 3-6 mL=1 point; cerebellum:≥24 mL=2 points, 12-24 mL=1 point), and intraventricular hemorrhage (1 point). AUROC of the location ICH score was higher in functional dependence (0.883 vs. 0.770, p = 0.002) but not mortality (0.838 vs. 0.841, p = 0.918) discrimination compared to the original ICH score. CONCLUSIONS: The interaction between hematoma volume and location exerted an independent effect on outcomes. Excellent discrimination of functional dependence and mortality was observed with incorporation of location-specific volume thresholds into a prediction model. Therefore, the volume-location relationship plays an important role in ICH outcome prediction.

The Intracerebral Hemorrhage Score: Changing Perspectives on Mortality and Disability.

BACKGROUND: Intracerebral hemorrhage (ICH) remains a devastating diagnosis. While the ICH Score continues to be used in the clinical setting to prognosticate outcomes, contemporary improvements in management have reduced mortality rates for each scoring tier. The aims of this study were to examine mortality rates within ICH Score strata and examine if these findings are stable when major disability is included in categorizing poor outcomes. METHODS: From a single-institution cohort built between 2009 and 2016, 582 patients were extracted based on the criteria for complete ICH Score, discharge mortality, and functional status for survivors. Mortality rates were stratified by ICH Score and compared with both historical and similar contemporary cohorts. Poor outcome was defined as severe disability (modified Rankin Scale score 5) in addition to death, stratified by ICH Score, and compared. A secondary analysis of patients with ICH Score of 2 was performed in light of the primary results. RESULTS: Mortality rates stratified by ICH Score were notably lower than expected for low- and moderate-grade ICH compared with the original cohort. However, when defining a poor outcome as including severe disability (modified Rankin Scale score 5) in addition to death, the rates for poor outcomes were higher for patients with ICH Score of 2 (51.16% vs. 26%, P = 0.017) and no different for any other score group compared with the original cohort. CONCLUSIONS: Though the original ICH Score overestimates mortality for low-grade and moderate-grade hemorrhages, it may underpredict severe disability.

Distributions and Reference Ranges for Automated Pupillometer Values in Neurocritical Care Patients.

BACKGROUND: Automated pupillometry is becoming widely accepted as an objective measure of pupillary function, especially in neurocritical care units. Normative reference values and thresholds to denote a significant change are necessary for integrating automated pupillometry into practice. OBJECTIVE: Providing point estimates of normal ranges for pupillometry data will help clinicians intuit meaning from these data that will drive clinical interventions. METHODS: This study used a planned descriptive analysis using data from a multicenter registry including automated pupillometry assessments in 2140 subjects from 3 US hospitals collected during a 3-year period. RESULTS: We provide a comprehensive list of admission pupillometry data. Our data demonstrate significant differences in pupillary values for Neurological Pupil Index, latency, and constriction velocity when stratified by age, sex, or severity of illness defined by the Glasgow Coma Scale score. CONCLUSION: This study provides a greater understanding of expected distributions for automated pupillometry values in a wide range of neurocritical care populations.
