Outcome Predictor of Spontaneous Supratentorial Intracerebral Hemorrhage Management

Background: Spontaneous intracerebral hemorrhage (SICH) is responsible for higher morbidity and mortality rates than ischemic stroke. Although SICH is less common than ischemic stroke. Identifying the predictors of outcome after spontaneous supratentorial intracerebral hemorrhage is crucial for a clinical decision-making framework and implementing efficient therapeutic measures. Aims: The study aimed to analyze the clinical profile, assess the outcome, and identify the outcome prognosticators after supratentorial SICH in the Neurosurgery Department of a tertiary care hospital in the southeastern part of Bangladesh. Materials and Methods: This prospective interventional study included 183 patients with computerized tomography (CT) evidence of supratentorial SICH above 18 years of age from the Department of Neurosurgery of Chittagong Medical College Hospital between September 2021 and February 2023.The variables analyzed were age, sex, comorbidities, Glasgow coma scale (GCS) score on admission, radiological features, treatment modality and outcome at 90-day. Glasgow outcome scale (GOS) score was used to assess the outcome. GOS score 4-5 was considered good outcome and GOS score 1-3 was considered as poor outcome. Results: The mean age of the patients was 58.9±14.4 years and 52.5% were male. The 90-day mortality rate was 50.8% and 55.2% patients had poor outcomes. On bivariate analysis, higher age, comorbid CKD state, low GCS score, higher hematoma volume, midline shift, hydrocephalus and intraventricular hematoma (IVH) were associated with poor outcome. Independent predictors of poor outcome included a higher baseline age (OR: 1.07, 95% CI:1.02-1.11, p=0.002), lower GCS on admission (OR: 0.55, 95% CI: 0.39- 0.76, p<0.001), and medical management (OR = 30.56, 95% CI = 7.15-130.69, P <0.001). Conclusions: In conclusion, SICH is associated with high mortality and morbidity. Higher age, low GCS on admission and medical management independently predicted poor outcome in the present study. Patients with a lower age, higher GCS on admission and who were managed surgically were more likely to have a good outcome. Bang. J Neurosurgery 2024; 13(2): 96-103

Study of etiology, clinical profile, and outcome of altered sensorium patients admitted in a tertiary care hospital

Background: Altered sensorium is one of the most common presentations in patients coming to the emergency room. It includes decreased level of consciousness, attention disorder, arousal disorder, and cognitive disorder. The causes of altered sensorium can be varied, some of which are cerebrovascular diseases, alcoholism, cerebral trauma, hypoglycemia, epilepsy, drug intoxication, and neuroinfection. 4–10% of the patients presenting to the emergency department may have altered mental status. The outcome is dependent on early identification and effective treatment using investigations and imaging technologies, and it might range from full recovery to permanent damage to death. Aims and Objectives: (1) To study clinical profile and etiology in altered sensorium patients. (2) To assess outcomes in altered sensorium patients. Materials and Methods: In this prospective cross-sectional study, clinical examination and investigations are done and data are collected using pro forma for patients fulfilling the inclusion criteria. In this study, all altered sensorium patients were evaluated by detailed history, clinical examination, Glasgow Coma Scale (GCS), laboratory investigations, computed tomography brain, and other investigations. All patients were followed up till discharge or death of the patient in the hospital. Results: There were 270 patients who presented with encephalopathy, 184 (68%) were males. The majority of these patients 60 (22.2%) were in the age group of 51–60 years old. The most common cause is neurological in 109 (40.3%) patients, metabolic in 64 (24%) patients, and sepsis in 50 (19%) patients. Ischemic stroke 83 (76%) is the most common neurological cause. Hepatic encephalopathy was the most common cause of metabolic encephalopathy present in 21 (32%) patients. Pneumonia was the most common infection. There were 114 (42.2%) deaths. Septic encephalopathy is the most common cause of mortality. Early presentation to the hospital, higher GCS, and conscious level at presentation were good prognostic markers of outcome in patients, while septic encephalopathy was found to have the worst prognosis. Conclusion: The common etiologies of encephalopathy are neurological followed by metabolic and sepsis. Early presentation to the emergency room within 6 h of symptom onset, higher GCS, neurological and metabolic causes are associated with a good prognosis. The mortality rate was 42.2%. Septic encephalopathy is the most common cause of death with pneumonia being the most common source of infection.

Wartime penetrating traumatic brain injury of the anterior skull base involving the paranasal sinuses: a single-center, first-year experience from Dnipro, Ukraine.

Since February 2022, the number of casualties in the Russian-Ukrainian war have dramatically increased, with a high incidence of penetrating traumatic brain injuries (pTBIs). To date, there has been limited evaluation of pTBI of the anterior skull base involving the paranasal sinuses. The objective of this study was to highlight the authors' experience with this injury pattern and identify specific factors associated with favorable short-term (1-month) outcome and survival. The authors conducted a single-institution retrospective review of patient data collected from the 1st year of the Russian-Ukrainian war at a frontline civilian Ukrainian hospital. To prevent complications from conservative treatment of pTBI with paranasal sinus injury, a protocol of early primary neurosurgical treatment including debridement/hematoma evacuation, repair of dural defects with vascularized pericranial flaps, and titanium plating of external/skull base defects was implemented. Using 1-month postoperative Glasgow Outcome Scale scores, the authors defined a favorable outcome as good recovery/moderate disability and a poor outcome as severe disability/vegetative state/death. Patient demographics, injury characteristics, imaging findings, and postoperative complications were assessed. Logistic regression models were used to estimate the effect of patient characteristics on unfavorable outcome or survival. From February 2022 to February 2023, there were 141 pTBIs (20%) involving the paranasal sinuses, 134 (95%) due to blast fragmentation. One hundred eighteen patients (84%) had a favorable outcome. Most patients with pTBIs (69%) had other nonbrain-related injuries. While 48 patients (34%) presented with preoperative CSF leak, only 1 patient (0.7%) had persistent postoperative CSF leak, which was managed with lumbar drainage. High admission Glasgow Coma Scale (GCS) score, favorable injury lateralization (single hemisphere involved), and low Injury Severity Score (ISS) were associated with significantly increased odds of favorable short-term outcome, whereas high admission GCS scores and no midline shift were associated with significantly increased odds of survival. This was the largest single-year study on neurosurgical treatment of wartime pTBI involving the paranasal sinuses. Implementation of primary neurosurgical intervention at the time of presentation demonstrated promising early results and a shift away from expectant management of this injury pattern. The association of high admission GCS score, low ISS, favorable injury lateralization, and no midline shift on favorable short-term outcomes or survival has not been previously documented with this injury pattern.

Traumatic brain injury outcomes at the “epicenter of the epicenter” of the united states COVID-19 pandemic amidst ongoing socio-demographic challenges

Abstract Introduction Traumatic brain injury (TBI) poses a significant public health challenge with profound impacts at individual, family, community, and societal levels. Early during the COVID-19 pandemic, the neighborhood of Elmhurst, Queens in New York City was a hotspot dubbed the “epicenter of the epicenter” of the crisis in the United States, requiring major changes in healthcare resource allocation. This study investigates how different phases of the COVID-19 pandemic affected the incidence, severity, and clinical outcomes of TBI in this geographical area. Methods TBI admissions to NYC Health + Hospitals/Elmhurst, a Level 1 Trauma Center, during the first six months of 2019, 2020, and 2021 were retrospectively analyzed. Data were grouped into three periods: pre-pandemic (1/1/19–6/30/19 and 1/1/20–2/29/20) [Group 1], first COVID-19 wave (3/1/20–6/30/20) [Group 2], and second COVID-19 wave (1/1/21–6/30/21) [Group 3]. Univariate analyses were conducted to explore factors potentially associated with TBI outcomes; variables that reached statistical significance (p < 0.05) were included in a binary logistic regression analysis dichotomized into good outcome (discharge to home or acute rehabilitation disposition) and poor outcome (discharge to skilled nursing facility/subacute rehabilitation, hospice, or in-hospital mortality). Results Analysis of 443 TBI patients (median age 56 [range 38, 73]; mean admissions/week 5.6 ± 2.7) demonstrated no significant variance in age (H = 0.92; p = 0.63), sex (χ2 = 1.4, p = 0.51), or ethnicity (χ2 = 17.1; p = 0.07) across groups. Group 2 had significantly fewer weekly admissions (3.9 ± 2.6) compared to Groups 1 (5.9 ± 2.2; p = 0.02) and 3 (6.1 ± 2.9; p = 0.01). Over the course of the pandemic, the proportion of uninsured patients decreased from 15 to 4%, while Medicaid and Medicare coverage rates rose from 25 to 41% and 20% to 28%, respectively (p < 0.001). A binary logistic regression model dichotomized by discharge outcome for all 443 TBI patients confirmed that increasing age (OR = 0.95; 95% CI 0.93–0.97; p < 0.001) and Injury Severity Score (OR = 0.88; 95% CI 0.83–0.93; p < 0.001) were inversely correlated with good outcome, while higher Glasgow Coma Scale (OR = 1.26; 95% CI 1.17–1.36; p < 0.001) was positively correlated. Of particular interest, Black/Hispanic ethnicity (OR = 0.36; 95% CI 0.19–0.66; p = 0.002) and public health insurance (Medicaid/Medicare) coverage (OR = 0.83; 95% CI 0.68–1.00; p = 0.05) were both associated with less favorable outcomes. Neither group designation, patient sex, COVID-19 status, or need for neurosurgical intervention was correlated with outcome (p > 0.05). Conclusion Despite the changes in TBI admission patterns throughout New York City during the COVID-19 pandemic, the quality of patient outcomes at our institution remained relatively consistent across the pandemic’s different phases, as assessed by discharge disposition. However, two important socioeconomic factors—ethnicity and health insurance status—were significantly associated with outcome, underscoring the need for systemic changes to address ongoing disparities in neurotrauma care.

Predicting 30-day mortality in severely injured elderly patients with trauma in Korea using machine learning algorithms: a retrospective study.

The number of elderly patients with trauma is increasing; therefore, precise models are necessary to estimate the mortality risk of elderly patients with trauma for informed clinical decision-making. This study aimed to develop machine learning based predictive models that predict 30-day mortality in severely injured elderly patients with trauma and to compare the predictive performance of various machine learning models. This study targeted patients aged ≥65 years with an Injury Severity Score of ≥15 who visited the regional trauma center at Chungbuk National University Hospital between 2016 and 2022. Four machine learning models-logistic regression, decision tree, random forest, and eXtreme Gradient Boosting (XGBoost)-were developed to predict 30-day mortality. The models' performance was compared using metrics such as area under the receiver operating characteristic curve (AUC), accuracy, precision, recall, specificity, F1 score, as well as Shapley Additive Explanations (SHAP) values and learning curves. The performance evaluation of the machine learning models for predicting mortality in severely injured elderly patients with trauma showed AUC values for logistic regression, decision tree, random forest, and XGBoost of 0.938, 0.863, 0.919, and 0.934, respectively. Among the four models, XGBoost demonstrated superior accuracy, precision, recall, specificity, and F1 score of 0.91, 0.72, 0.86, 0.92, and 0.78, respectively. Analysis of important features of XGBoost using SHAP revealed associations such as a high Glasgow Coma Scale negatively impacting mortality probability, while higher counts of transfused red blood cells were positively correlated with mortality probability. The learning curves indicated increased generalization and robustness as training examples increased. We showed that machine learning models, especially XGBoost, can be used to predict 30-day mortality in severely injured elderly patients with trauma. Prognostic tools utilizing these models are helpful for physicians to evaluate the risk of mortality in elderly patients with severe trauma.

Analysis of the efficacy of hyperbaric oxygen therapy for disorders of consciousness: A retrospective cohort study.

To analyze the efficacy and associated factors affecting the prognosis in patients with disturbance of consciousness after hyperbaric oxygen (HBO) treatment. A retrospective study was carried out on patients with disorders of consciousness (DOC) receiving HBO treatment from January to January 2022 in the Second Department of Rehabilitation Medicine of the Second Hospital of Hebei Medical University, China. HBO therapy improved the Glasgow Coma Scale (GCS) and Chinese Nanjing Persistent Vegetative State Scale (CNPVSS), as well as the clinical efficacy in patients with DOC. The comparison of GCS and CNPVSS scores in patients with DOC before and after HBO treatment was all statistically significant, with 325 patients (67.1%) showing effective results and 159 patients (32.9%) having unchanged outcomes. Univariate analysis indicated that there were statistically significant differences in age, HBO intervention time, HBO treatment times, pre-treatment GCS score, and etiology and underlying diseases between the good and poor prognoses groups. Multivariate regression analysis showed that HBO intervention time ≤7 days, HBO treatment ＞ times, high GCS score before HBO treatment, and brain trauma were independent influencing factors in achieving a good prognosis for patients with DOC. Low pre-treatment GCS scores were an independent risk factor for a poor prognosis in patients with brain trauma while being male, late HBO intervention time, fewer HBO treatment times, and low pre-treatment GCS scores were independent risk factors for a poor prognosis in patients with DOC after a stroke. Being ≥50 years of age, late HBO intervention time, and low pre-treatment GCS scores were independent risk factors for a poor prognosis in patients with DOC after hypoxic-ischaemic encephalopathy. HBO therapy can improve the GCS, CNPVSS scores and clinical efficacy in patients with DOC, and the timing of HBO intervention ≤7 days, times of HBO treatment, high pre-treatment GCS score, and brain trauma were the independent influencing factors of good prognosis in patients with DOC.

Pelvic fractures in blunt trauma patients: A comparative study.

Pelvic fractures (PF) with concomitant injuries are on the rise due to an increase of high-energy trauma. Increase of the elderly population with age related comorbidities further complicates the management. Abdominal organ injuries are kindred with PF due to the proximity to pelvic bones. Presence of contrast blush (CB) on computed tomography in patients with PF is considered a sign of active bleeding, however, its clinical significance and association with outcomes is debatable. To analyze polytrauma patients with PF with a focus on the geriatric population, co-injuries and the value of contrast blush. This retrospective cohort study included 558 patients with PF admitted to level 1 trauma center (01/2017-01/2023). Analyzed variables included: Age, sex, mechanism of injury (MOI), injury severity score (ISS), Glasgow coma scale (GCS), abbreviated injury scale (AIS), co-injuries, transfusion requirements, pelvic angiography, embolization, laparotomy, orthopedic pelvic surgery, intensive care unit and hospital lengths of stay, discharge disposition and mortality. The study compared geriatric and non-geriatric patients, patients with and without CB and abdominal co-injuries. Propensity score matching was implemented in comparison groups. PF comprised 4% of all trauma admissions. 89 patients had CB. 286 (52%) patients had concomitant injuries including 93 (17%) patients with abdominal co-injuries. Geriatric patients compared to non-geriatric had more falls as MOI, lower ISS and AIS pelvis, higher GCS, less abdominal co-injuries, similar CB and angio-embolization rates, less orthopedic pelvic surgeries, shorter lengths of stay and higher mortality. After propensity matching, orthopedic pelvic surgery rates remained lower (8% vs 19%, P < 0.001), hospital length of stay shorter, and mortality higher (13% vs 4%, P < 0.001) in geriatric patients. Out of 89 patients with CB, 45 (51%) were embolized. After propensity matching, patients with CB compared to without CB had more pelvic angiography (71% vs 12%, P < 0.001), higher embolization rates (64% vs 22%, P = 0.02) and comparable mortality. Half of the patients with PF had concomitant co-injuries, including abdominal co-injuries in 17%. Similarly injured geriatric patients had higher mortality. Half of the patients with CB required an embolization.

Effect of early mobilization on the development of pneumonia in patients with traumatic brain injury in the neurosurgical intensive care unit: A historical controls study.

Pneumonia has a high incidence in traumatic brain injury (TBI) patients and lacks effective treatments. Early mobilization (EM) may be a potentially effective treatment. To explore the impact of EM on TBI-related pneumonia in the neurosurgical intensive care unit (NICU). This study was a historical control study. 100 TBI patients who received EM intervention were prospectively included as the experimental group (EM cohort), and 250 TBI patients were retrospectively included as the control group. The propensity score matching (PSM) method was employed to balance baseline and minimize potential bias. The relationship between EM and TBI-related pneumonia was investigated by univariate and multivariate logistic regression, then further determined by subgroup analysis. The influence of other variables was excluded by interaction analyses. Finally, the effect of EM on the prognosis of TBI patients was analysed by comparing the Glasgow Coma Scale (GCS) and the hospital stay. After screening, 86 patients were included in the EM cohort and 199 patients were included in the control cohort. There were obvious differences between the two cohorts at baseline, and these differences were eliminated after PSM, when the incidence of pneumonia was significantly lower in the EM cohort than in the control cohort (35.0% vs. 61.9%, p < .001). Multivariate logistic regression showed that EM was an independent risk factor for TBI-related pneumonia and was significantly associated with a decreased incidence of pneumonia. This correlation was present in most subgroups and was not affected by other variables (p for interaction >.05). Patients in the EM cohort had shorter length of ICU stay (6 vs. 7 days, p = .017) and higher GCS at discharge (12 vs. 11, p = .010). EM is a safe and effective treatment for TBI patients in NICU, which can reduce the incidence of pneumonia, help to improve prognosis and shorten the length of ICU stay. Although the utilization rate of EM is low in TBI patients for various reasons, EM is still an effective method to prevent complications. Our study confirms that a scientific and detailed EM strategy can effectively reduce the incidence of pneumonia while ensuring the safety of TBI patients, which is worthy of further research and clinical application.

Implementation of early prophylaxis for deep-vein thrombosis in intracerebral hemorrhage patients: an observational study from the Chinese Stroke Center Alliance

BackgroundThere is substantial evidence to support the use of several methods for preventing deep-vein thrombosis (DVT) following intracerebral hemorrhage (ICH). However, the extent to which these measures are implemented in clinical practice and the factors influencing patients’ receipt of preventive measures remain unclear. Therefore, we aimed to evaluate the rate of the early implementation of DVT prophylaxis and the factors associated with its success in patients with ICH.MethodsThis study enrolled 49,950 patients with spontaneous ICH from the Chinese Stroke Center Alliance (CSCA) between August 2015 and July 2019. Early DVT prophylaxis implementation was defined as an intervention occurring within 48 h after admission. Univariate and multivariate logistic regression analyses were conducted to identify the rate and factors associated with the implementation of early prophylaxis for DVT in patients with ICH.ResultsAmong the 49,950 ICH patients, the rate of early DVT prophylaxis implementation was 49.9%, the rate of early mobilization implementation was 29.49%, and that of pharmacological prophylaxis was 2.02%. Factors associated with an increased likelihood of early DVT prophylaxis being administered in the multivariable model included receiving early rehabilitation therapy (odds ratio [OR], 2.531); admission to stroke unit (OR 2.231); admission to intensive care unit (OR 1.975); being located in central (OR 1.879) or eastern regions (OR 1.529); having a history of chronic obstructive pulmonary disease (OR 1.292), ischemic stroke (OR 1.245), coronary heart disease or myocardial infarction (OR 1.2); taking antihypertensive drugs (OR 1.136); and having a higher Glasgow Coma Scale (GCS) score (OR 1.045). Conversely, being male (OR 0.936), being hospitalized in tertiary hospitals (OR 0.778), and having a previous intracranial hemorrhage (OR 0.733) were associated with a lower likelihood of early DVT prophylaxis being administered in patients with ICH.ConclusionsThe implementation rate of early DVT prophylaxis among Chinese patients with ICH was subpar, with pharmacological prophylaxis showing the lowest prevalence. Various controllable factors exerted an impact on the implementation of early DVT prophylaxis in this population.

Association of inflammatory cytokines expression in cerebrospinal fluid with the severity and prognosis of spontaneous intracerebral hemorrhage

ObjectiveTo investigate the potential diagnostic and prognostic implications of inflammatory cytokine levels in the cerebrospinal fluid (CSF) of patients with spontaneous intracerebral hemorrhage (SICH) upon their initial hospital admission.MethodsOur cohort included 100 patients diagnosed with acute SICH, presenting to the Department of Neurosurgery. Additionally, we recruited 50 individuals without central nervous system (CNS) pathology, treated concurrently at our facility, as controls. CSF samples, collected upon hospital entry, were quantitatively assessed for 10 inflammatory cytokines using the Mesoscale Discovery Platform (MSD, Rockville, MD, USA) electrochemiluminescence technology, followed by validation through enzyme-linked immunosorbent assay (ELISA).ResultsWe observed a marked elevation of IL-6, IL-8, IL-10, and TNF-α in the CSF of the SICH subgroup compared to controls. Higher Glasgow Coma Scale (GCS) scores in SICH patients corresponded with lower CSF concentrations of IL-6, IL-8, IL-10, and TNF-α, indicating an inverse relationship. Notably, CSF inflammatory cytokine levels were consistently higher in SICH patients with hydrocephalus than in those without. Increases in IL-6, IL-8, IL-10, and TNF-α in the CSF were notably more pronounced in the poor prognosis group (Glasgow Outcome Scale, GOS 1–3) compared to those with a favorable prognosis (GOS 4–5). The AUC values for these cytokines in predicting SICH prognosis were 0.750, 0.728, 0.717, and 0.743, respectively.ConclusionsInitial CSF levels of IL-6, IL-8, IL-10, and TNF-α upon admission provide significant insights into the severity of neural damage and are robust indicators for prognosis in SICH patients.

The role of serum adropin in determining the clinical outcomes of patients with traumatic brain injury: a case-control study.

It has been determined that adropin has a role in tissue healing. This study aimed to determine the effects of head trauma on the tissues and blood levels of patients admitted to the emergency department. The study group was divided into two to compare the adropin level in healthy individuals and patients with head trauma. Blood tests from patients and healthy volunteers were compared using the adropin kit. Adropin levels, Glasgow Coma Scale, and revised scores of trauma patients were recorded and analyzed. All patients in the trauma group had significantly higher adropin levels than the control group. Among these patients, the adropin level of the discharged patients was higher than the others. In addition, patients with high Glasgow Coma Scale and normal blood pressure were found to have higher adropin levels than the others. Although adropin cannot make a sharp distinction in determining the prognosis, the increase in its level in trauma patients shows that it triggers a protective mechanism.

Prevalence and Outcome of Sepsis: Mortality and Prolonged Intensive Care Unit Stay among Sepsis Patients Admitted to a Tertiary Centre in Malaysia.

Sepsis and septic shock are the leading causes of critical care-related mortality worldwide. This study aimed to determine the prevalence of sepsis, its intensive care unit (ICU) mortality rate and the factors associated with both ICU mortality and prolonged stay. A prospective cohort study was conducted from January 2019 to December 2019 with adult patients presenting evidence of sepsis who were admitted to the ICU. Parameters were assessed in the ICU to determine the association with all-cause ICU mortality and prolonged stay. Out of 607 adults, 292 with sepsis were admitted to the ICU in 2019, with a mean age of 50.98 (standard deviation [SD] = 17.75) years old. There was, thus, a 48% incidence of sepsis. Mortality was observed in 78 patients (mortality rate = 26.7%) (95% confidence interval [CI]: 21.7, 32.2). Patients with higher Glasgow coma scale (GCS) scores had lower odds of ICU mortality (adjusted odds ratio [OR] = 0.90; 95% CI: 0.82, 0.98; P = 0.019), while patients with higher sequential organ failure assessment (SOFA) scores had higher odds (adjusted OR = 1.22; 95% CI: 1.11, 1.35; P < 0.001). Eighty patients (37.4%) who survived had prolonged ICU stays (95% CI: 30.9, 44.2). Patients with higher albumin levels had lower odds of a prolonged ICU stay (adjusted OR = 0.94; 95% CI: 0.90, 0.98; P = 0.006) and patients on renal replacement therapy had higher odds of a prolonged ICU stay (adjusted OR = 1.25; 95% CI: 1.74, 7.12; P < 0.001). Our study identified a sepsis prevalence of 48% and an ICU mortality rate of 26.7% among adult patients admitted to the ICU. GCS and SOFA scores were the most important factors associated with ICU mortality.

Cost Associated with Geriatric Traumatic Brain Injury in Developing Countries: An Observational Study

Traumatic brain injury (TBI) in the geriatric population is a serious public health problem and has a huge impact on mortality and morbidity. A retrospective cohort study including patients aged above 65 admitted to a tertiary specialized trauma center, in the period from January 2016 to 31 December 2019. The data collected include patients' demographics, diagnosis, Glasgow Coma Scale (GCS) on arrival, length of stay, investigations, and type of surgery done. Total number of TBI cases in our study is 145. The most frequent single diagnosis was subdural hematoma (85). Subsequently, it was the costliest diagnosis with an average cost of 3569 USD per patient. Length of stay on average was 17.11 ± 41hours, with the majority (109 patients) having nonprolonged hospital stay (<14days). Most of those managed by observation have below-average costs compared to other patients (P<0.001). Complete blood count was the highly requested test with a total cost 5070 $ in the study period. And head computed tomography had the highest total cost 58,864 $. 21 craniotomies and 30 burr holes were made with a total cost of 30,000 and 25,325 respectively. Patients with lower GCS (64.6%) have below-average hospitalization costs compared to those who got high GCS scores (P<0.001). This study provides the first estimates of the financial burden of Geriatric TBI in the region, which signifies the importance of developing strategies to prevent TBIs and help in resource allocation and healthcare policy formation.

31 Characterizing Sociodemographic Factors Associated with the Cognitive and Linguistic Scale (CALS) Among Pediatric Rehabilitation Patients Admitted for Traumatic Brain Injury

Objective:Extant literature suggests significant heterogeneity in recovery trajectories after experiencing a moderate to severe traumatic brain injury (TBI) during childhood (Moran et al., 2016). The Cognitive and Linguistic Scale (CALS) is a promising non-norm-referenced measure designed for serial monitoring within an inpatient rehabilitation setting that may optimize prediction of acute recovery and long-term neuropsychological functioning. To date, the CALS has primarily been examined in the context of injury characteristics such as severity and etiology (e.g., Slomine et al., 2016), and it is unclear what non-injury factors may be relevant to consider. Using archival data gathered from an inpatient pediatric neurorehabilitation program, this study examined associations between the CALS and select sociodemographic factors to better inform the clinical utility of the measure.Participants and Methods:Participants included 56 youth (46% BIPOC, 66% male) aged 2-17 years (M = 12.40, SD = 3.99) who were admitted for moderate to severe TBI to an inpatient rehabilitation program at a regional tertiary care children’s hospital. Data extracted from medical records included demographic information (i.e., age at injury, sex, ethnoracial identity, address, initial Glasgow Coma Scale (GCS) rating, CALS at admission, and full-scale IQ (FSIQ) at discharge. GCS was used as a proxy for injury severity. Residential addresses were geocoded and area-level median income was used as a proxy for familial socioeconomic status (SES). A multiple regression model was utilized to parse the individual contributions of demographic variables) on initial CALS performance while accounting for injury severity. Parallel regression models were used to determine whether patient characteristics moderate the association between initial CALS performance and cognitive functioning at discharge.Results:Preliminary analyses demonstrated that there were no significant associations between GCS and demographic variables, ps &gt; .05. Patient age at injury was significantly associated with CALS total score at admission above and beyond injury severity and other demographic characteristics, t (31) = 2.55, p = .016, such that older age was associated with higher initial CALS scores. Results of moderator analyses between CALS and patient characteristics showed a significant main effect of injury severity, such that higher GCS was associated with higher FSIQ at discharge across models, ps &lt; .05. No significant interactions were identified.Conclusions:These findings provide additional evidence for the generalizability of the CALS and further characterize its associations with non-injury factors, which is important for better understanding aspects that contribute to recovery trajectories and outcomes after moderate to severe TBI. Given the longstanding challenges in regard to the validity of neuropsychological assessment for diverse groups, it is critical to explicitly examine cultural context when considering the clinical utility of a measure. A limitation of the current study is the utilization of broad demographic information due to limited availability of sociocultural data. Future research should examine more granular and culturally-specific variables that may impact CALS performance (e.g., educational attainment, linguistic considerations), beyond using broad-based demographic data as a proxy for sociocultural factors. Another important next step is to utilize serial administrations of the CALS to examine the impact of sociocultural factors on recovery trajectories following TBI.

Predictive Modeling and Integrated Risk Assessment of Postoperative Mortality and Pneumonia in Traumatic Brain Injury Patients through Clustering and Machine Learning: Retrospective Study.

This study harnessed machine learning to forecast postoperative mortality (POM) and postoperative pneumonia (PPN) among surgical traumatic brain injury (TBI) patients. Our analysis centered on the following key variables: Glasgow Coma Scale (GCS), midline brain shift (MSB), and time from injury to emergency room arrival (TIE). Additionally, we introduced innovative clustered variables to enhance predictive accuracy and risk assessment. Exploring data from 617 patients spanning 2012 to 2022, we observed that 22.9% encountered postoperative mortality, while 30.0% faced postoperative pneumonia (PPN). Sensitivity for POM and PPN prediction, before incorporating clustering, was in the ranges of 0.43-0.82 (POM) and 0.54-0.76 (PPN). Following clustering, sensitivity values were 0.47-0.76 (POM) and 0.61-0.77 (PPN). Accuracy was in the ranges of 0.67-0.76 (POM) and 0.70-0.81 (PPN) prior to clustering and 0.42-0.73 (POM) and 0.55-0.73 (PPN) after clustering. Clusters characterized by low GCS, small MSB, and short TIE exhibited a 3.2-fold higher POM risk compared to clusters with high GCS, small MSB, and short TIE. In summary, leveraging clustered variables offers a novel avenue for predicting POM and PPN in TBI patients. Assessing the amalgamated impact of GCS, MSB, and TIE characteristics provides valuable insights for clinical decision making.

Factors Associated With Early Discharge in Pediatric Trauma Patients Transported by Rotor: A Retrospective Analysis

ObjectiveHelicopter emergency medical services (HEMS) play a crucial role in providing timely transport for pediatric trauma patients. This service carries the highest risk of any mode of medical transport and a high financial burden, and patient outcomes are seldom investigated. This study evaluated the characteristics of pediatric trauma patients discharged within 24 hours after transport by HEMS. MethodsThis was a single-center, retrospective analysis on pediatric trauma patients transported by HEMS from 2019 to 2022. Analyses were performed to identify factors associated with discharge within 24 hours. Factors analyzed included vital signs, Shock Index, Pediatric Age-Adjusted scores, management details, and clinical outcomes. ResultsA total of 466 pediatric trauma patients were transported by HEMS, including 171 patients (36.7%) who were discharged within 24 hours. There were no differences in the rates of blunt and penetrating injury (P = .583). Patients discharged within 24 hours were more likely to have a higher Glasgow Coma Scale score (14 vs. 11, P < .001) and a lower Injury Severity Score (4.9 vs. 14.7, P < .001), required less prehospital fluid resuscitation (5.5 vs. 11.7 mL/kg, P = .039), and had higher levels of serum calcium (9.3 vs. 8.9 mg/dL, P < .001). They were also less likely to meet criteria for level 1 trauma activation (13.0% vs. 40%, P < .001) or to require prehospital respiratory support of any kind (4.1% vs. 31.1%, P < .001). After arrival at the hospital, they were less likely to require blood transfusions (2.9% vs. 29.8%, P < .001) or tranexamic acid (2.9% vs. 11.5%, P = .001). ConclusionTrauma patients with a high Glasgow Coma Scale score and a low Injury Severity Score who do not require critical care or meet the criteria for high-level trauma activation may be suitable for transportation with lower acuity. Further studies aimed at improving triage and implementing improved criteria for the use of HEMS are paramount.

Impact of premorbid oral anticoagulant use on survival in patients with traumatic intracranial hemorrhage.

Although oral anticoagulant use has been implicated in worse outcomes for patients with a traumatic brain injury (TBI), prior studies have mostly examined the use of vitamin K antagonists (VKAs). In an era of increasing use of direct oral anticoagulants (DOACs) in lieu of VKAs, the authors compared the survival outcomes of TBI patients on different types of premorbid anticoagulation medications with those of patients not on anticoagulation. The authors retrospectively reviewed the records of 1186 adult patients who presented at a level I trauma center with an intracranial hemorrhage after blunt trauma between 2016 and 2022. Patient demographics; comorbidities; and pre-, peri-, and postinjury characteristics were compared based on premorbid anticoagulation use. Multivariable Cox proportional hazards regression modeling of mortality was performed to adjust for risk factors that met a significance threshold of p < 0.1 on bivariate analysis. Of 1186 patients with a traumatic intracranial hemorrhage, 49 (4.1%) were taking DOACs and 53 (4.5%) used VKAs at the time of injury. Patients using oral anticoagulants were more likely to be older (p < 0.001), to have a higher Charlson Comorbidity Index (p < 0.001), and to present with a higher Glasgow Coma Scale (GCS) score (p < 0.001) and lower Injury Severity Score (ISS; p < 0.001) than those on no anticoagulation. Patients using VKAs were more likely to undergo reversal than patients using DOACs (53% vs 31%, p < 0.001). Cox proportional hazards regression demonstrated significantly increased hazard ratios (HRs) for VKA use (HR 2.204, p = 0.003) and DOAC use (HR 1.973, p = 0.007). Increasing age (HR 1.040, p < 0.001), ISS (HR 1.017, p = 0.01), and Marshall score (HR 1.186, p < 0.001) were associated with an increased risk of death. A higher GCS score on admission was associated with a decreased risk of death (HR 0.912, p < 0.001). Patients with a traumatic intracranial injury who were on oral anticoagulant therapy before injury demonstrated higher mortality rates than patients who were not on oral anticoagulation after adjusting for age, comorbid conditions, and injury presentation.

A multicenter observational study on outcomes of moderate and severe pediatric traumatic brain injuries-time to reappraise thresholds for treatment.

Children with moderate traumatic brain injury (modTBI) (Glasgow Coma Scale (GCS) 9-13) may benefit from better stratification. We aimed to compare neurocritical care utilization and functional outcomes between children with high GCS modTBI (hmodTBI, GCS 11-13), low GCS modTBI (lmodTBI, GCS 9-10), and severe TBI (sTBI, GCS ≤ 8). We hypothesized that patients with lmodTBI have higher neurocritical care needs and worse outcomes than patients with hmodTBI and are similar to patients with sTBI. Prospective observational study from June 2018 to October 2022 in 28 pediatric intensive care units (PICU) in Asia, South America, and Europe. We included children (age < 18years) with modTBI and sTBI admitted to PICU and measured functional outcomes at 3months using the Glasgow Outcome Scale-Extended Pediatric Revision (GOS-E Peds, scale 1-8, 1 = upper good recovery, 8 = death). We analyzed 409 patients: 98 (24%) and 311 (76%) with modTBI and sTBI, respectively. Patients with lmodTBI (vs. hmodTBI) were more likely to have invasive ICP monitoring (32.3% vs. 4.5%, p < 0.001), longer PICU stay (days, median [IQR]; 5.00 [4.00, 9.75] vs 4.00 [2.00, 5.00], p = 0.007), and longer hospital stay (days, median [IQR]: 13.00 [8.00, 17.00] vs. 8.00 [5.00, 12, 25], p = 0.015). Median GOS-E Peds scores were significantly different (hmodTBI (1.00 [1.00, 3.00]), lmodTBI (3.00 [IQR 2.00, 5.75]), and sTBI (5.00 [IQR 1.00, 6.00]) (p < 0.001)). After adjusting for age, sex, presence of polytrauma and cerebral edema, lmodTBI, and sTBI remained significantly associated with higher GOS-E scores (adjusted coefficient (standard error): 1.24 (0.52), p = 0.018, and 1.27 (0.33), p < 0.001, respectively) compared with hmodTBI. Children with lmodTBI have higher rates of neurocritical care utilization and worse functional outcomes than those with hmodTBI but better than those with sTBI. Children with lmodTBI may benefit from guideline-based management similar to what is implemented in children with sTBI. This work was performed in hospitals within the PACCMAN and LARed networks.

Patient Outcomes in Traumatic Subarachnoid Hemorrhage: A Retrospective Analysis

IntroductionPatients with isolated traumatic subarachnoid hemorrhage (itSAH) are often transferred to a Level I or II trauma center for neurosurgical evaluation. Recent literature suggests that some patients, such as those with high Glasgow Coma Scale (GCS) scores, may be safely observed without neurosurgical consultation. The objective of this study was to investigate characteristics of patients with itSAH to determine the clinical utility of neurosurgical evaluation and repeat imaging. Materials and methodsA retrospective chart review of 350 patients aged ≥ 18 y with initial computed tomography head (CTH) showing itSAH and GCS scores of 13-15. Patient demographics, medical history, medications, length of stay, transfer status, injury type and severity, and CTH results were extracted for analysis. Bivariate analyses were conducted to determine whether any factors were associated with a worsening repeat CTH. ResultsMost patients were female (57.4%) with blunt injuries (99.1%). The median age was 73 y. Neurosurgery was consulted for 342 (97.7%) patients, with one (0.3%) requiring intervention. Of 311 (88.9%) repeat imaging, 16 (5.1%) showed worsening. Factors with statistically significant associations with worsening CTH included injury severity; neurological deficit; lengths of stay; and a history of congestive heart failure, cirrhosis, or substance use disorder. ConclusionsThe findings suggest that patients with itSAH and high GCS scores may be able to be managed safely without neurosurgical oversight. The factors strongly associated with worsening CTH may be useful in identifying patients who need transfer for intensive care. Further research is needed to confirm these findings and develop appropriate management strategies for patients with itSAH.

Functional Outcomes at 6 and 12 Months Post-Injury in a Trauma Centre Population with Moderate-to-Severe Traumatic Injuries.

This study aims to evaluate the global functional outcomes after moderate-to-severe traumatic injury at 6 and 12 months and to examine the sociodemographic and injury-related factors that predict these outcomes. A prospective cohort study was conducted in which trauma patients of all ages with a New Injury Severity Score > 9 who were discharged alive from two regional trauma centres in Norway over a one-year period (2020) were included. The Glasgow Outcome Scale Extended (GOSE) score was used to analyse the functional outcomes. Regression analyses were performed to investigate the predictors of the GOSE score. Follow-up assessments were obtained from approximately 85% of the 601 included patients at both time points. The mean (SD) GOSE score was 6.1 (1.6) at 6 months and 6.4 (1.6) at 12 months, which corresponds to an upper-moderate disability. One-half of the patients had a persistent disability at 12 months post-injury. The statistically significant predictors of a low GOSE score at both time points were more pre-injury comorbidity, a higher number of injuries, and higher estimated rehabilitation needs, whereas a thorax injury with an Abbreviated Injury Scale ≥ 3 predicted higher GOSE scores. A high Glasgow Coma Scale score at admission predicted a higher GOSE score at 6 months. This study strengthens the evidence base for the functional outcomes and predictors in this population.
