Abstract
Introduction Early discharge from the emergency department (ED) or a 6-hour observation in the ED are two methods for management of patients with mild traumatic brain injury (mTBI) with normal brain computed tomography (CT) scan. This study aimed to compare the outcomes of the two management options. Methods This study is a single-center, open-label, pilot randomized case control study conducted in the ED of Ramathibodi Hospital from June 2022 to September 2023. Eligible participants included all individuals with mTBI who had negative findings on Brain CT scans. They were randomly assigned to either the early ED discharge or 6-hour ED observation group and compared regarding the outcomes (rate of 48-hour ED revisits; occurrence of post-concussion syndrome (PCS) 1 day, 1 month, and 3 months after the initial injury; and 3-month mortality). Results 122 patients with the mean age of 74.62 ± 14.96 (range: 25-99) years were consecutively enrolled (57.37% female). No significant differences were observed between the early discharge and observation groups regarding the severity of TBI (p=0.853), age (p=0.334), gender (p=0.588), triage level (p=0.456), Glasgow Coma Scale (GCS) score (p=0.806), comorbidities (p=0.768), medication usage (p=0.548), mechanism of injury (p=0.920), indication for brain CT scan (p=0.593), time from TBI onset to ED arrival (p=0.886), and time from ED triage to brain CT scan (p=0.333). Within 48 hours after randomization, the incidence of revisits was similar between the two groups (1.57% vs. 3.23%; p = 1.000). There were no statistically significant differences in the incidence of PCS between the early discharge and observation groups at 1 day (33.90% vs. 35.48%, p = 0.503), at 1 month (12.07% vs. 13.11%, p = 0.542), and at 3 months (1.92% vs. 5.56%, p = 0.323) after randomization. After a three-month follow-up period, four patients in the early discharge group, had expired (none of the deaths were associated with TBI). Conclusion It seems that, in mTBI patients with normal initial brain CT scan and the absence of other injuries or neurological abnormalities, early discharge from the ED without requiring observation could be considered safe.

Risk factors for intracerebral hemorrhage in small-vessel disease and non-small-vessel disease etiologies-an observational proof-of-concept study. Front Neurol 2024; 15:1322442. [PMID: 38515448 PMCID: PMC10954881 DOI: 10.3389/fneur.2024.1322442] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/16/2023] [Accepted: 02/19/2024] [Indexed: 03/23/2024] Open
Abstract
Background Sporadic cerebral small-vessel disease (CSVD), i.e., hypertensive arteriopathy (HA) and cerebral amyloid angiopathy (CAA), is the main cause of spontaneous intracerebral hemorrhage (ICH). Nevertheless, a substantial portion of ICH cases arises from non-CSVD etiologies, such as trauma, vascular malformations, and brain tumors. While studies compared HA- and CAA-related ICH, non-CSVD etiologies were excluded from these comparisons and are consequently underexamined with regard to additional factors contributing to increased bleeding risk beyond their main pathology. Methods As a proof of concept, we conducted a retrospective observational study in 922 patients to compare HA, CAA, and non-CSVD-related ICH with regard to factors that are known to contribute to spontaneous ICH onset. Medical records (available for n = 861) were screened for demographics, antithrombotic medication, and vascular risk profile, and CSVD pathology was rated on magnetic resonance imaging (MRI) in a subgroup of 185 patients. The severity of CSVD was assessed with a sum score ranging from 0 to 6, where a score of ≥2 was defined as advanced pathology. Results In 922 patients with ICH (median age of 71 years), HA and CAA caused the majority of cases (n = 670, 73%); non-CSVD etiologies made up the remaining quarter (n = 252, 27%). Individuals with HA- and CAA-related ICH exhibited a higher prevalence of predisposing factors than those with non-CSVD etiologies. This includes advanced age (median age: 71 vs. 75 vs. 63 years, p < 0.001), antithrombotic medication usage (33 vs. 37 vs. 19%, p < 0.001), prevalence of vascular risk factors (70 vs. 67 vs. 50%, p < 0.001), and advanced CSVD pathology on MRI (80 vs. 89 vs. 51%, p > 0.001). However, in particular, half of non-CSVD ICH patients were either aged over 60 years, presented with vascular risk factors, or had advanced CSVD on MRI. Conclusion Risk factors for spontaneous ICH are less common in non-CSVD ICH etiologies than in HA- and CAA-related ICH, but are still frequent. Future studies should incorporate these factors, in addition to the main pathology, to stratify an individual's risk of bleeding.

Abstract
Mild traumatic brain injury (TBI) and concussion can have serious consequences that develop over time with unpredictable levels of recovery. Millions of concussions occur yearly, and a substantial number result in lingering symptoms, loss of productivity, and lower quality of life. The diagnosis may not be made for multiple reasons, including due to patient hesitancy to undergo neuroimaging and inability of imaging to detect minimal damage. Biomarkers could fill this gap, but the time needed to send blood to a laboratory for analysis made this impractical until point-of-care measurement became available. A handheld blood test is now on the market for diagnosis of concussion based on the specific blood biomarkers glial fibrillary acidic protein (GFAP) and ubiquitin carboxyl terminal hydrolase L1 (UCH-L1). This paper discusses rapid blood biomarker assessment for mild TBI and its implications in improving prediction of TBI course, avoiding repeated head trauma, and its potential role in assessing new therapeutic options. Although we focus on the Abbott i-STAT TBI plasma test because it is the first to be FDA-cleared, our discussion applies to any comparable test systems that may become available in the future. The difficulties in changing emergency department protocols to include new technology are addressed.

Abstract
Introduction Inadequate spinal motion restriction in patients suffering from spinal injuries could lead to further neurological damage, ultimately worsening their prognosis. This study aimed to investigate the efficacy of long spinal boards (LSB), ske stretcher, and vacuum mattress for cervical spine immobilization during transportation of patients by measuring the angular motion of the cervical spine following lifting, transferring, and tilting. Methods We conducted an experimental study using a box of three randomizations and crossover designs without a washout period effect for the long spinal board, sked stretcher, and vacuum mattress. We concealed the randomization with sequentially numbered, opaque, sealed envelopes (SNOSE). Kinematic data were collected using eight optoelectronic cameras at 200 Hz (BTS Bioengineering, Milan, Italy) in triangular planes (lateral bending, flexion-extension, and axial rotation) while performing all three motions (static lift-hold, transfer, and 90° tilt). Results 12 cases (7 males and 5 females) with the mean age of 20 ± 3.03 (range: 18-28) years were studied. The three highest angular motions were observed in the axial rotation plane during patient's tilting under immobilization on all devices (Vacuum mattress having the highest value of 99.01±8.93, followed by the LSB at 89.89±34.35 and the sked stretcher at 86.30±7.73 degrees). During patient lifting, a higher angular motion was observed with vacuum mattress immobilization in flexion extension (Coefficient = 4.45; 95%CI: 0.46 - 8.45; p =0.029) and axial rotation (Coefficient = 3.70; 95%CI: 0.58 - 6.81; p =0.020) planes. During patient transfer, a higher angular motion was observed with sked stretcher in the flexion-extension plane (Coefficient = 2.98; 95%CI: 0.11 - 5.84; p = 0.042). During patient tilting to 90 degrees, a higher angular motion was observed with vacuum mattress immobilization in lateral bending (Coefficient = -4.08; 95%CI: -7.68 - -0.48; p = 0.026) for the vacuum mattress. Conclusion Based on the finding of the present study, patients on the vacuum mattress experience significantly higher angular motion in flexion extension and axial rotation during lifting, as well as lateral bending during 90-degree tilting. In addition, patients on the sked stretcher showed significantly higher angular motion in flexion-extension during the transferring. However, the predictive margins for immobilization across all devices did not demonstrate clinically significant differences among the three immobilization devices.

Abstract
Background: Intracranial hemorrhage is a complication of head injury. The initial assessment of the consciousness using Glasgow Coma Scale (GCS) shows severity level of head injury since arriving to the hospital. The GCS score is also known to have association with the presence of intracranial bleeding caused by head injury. This finding helps doctor lived in rural area with no facility of computed tomography (CT) scan to predict the intracranial haemorrhage by assessing the level of consciousness correctly using GCS score. Methods: This study is an observational analytic study using a cross-sectional design. The research was conducted in Dr. Moewardi Hospital for 6 months starting from July to October 2020. The population was all patients with head injury and were then examined by CT scan of head. The 61 subjects were established through the inclusion and the exclusion criteria. Results: There were 61 patients in this study. The reliability test of CT-Scan instrument used Kappa-Cohen test which showed the K value of 0.875 with p < 0.001. The finding of moderate-severe head injury (GCS score 3-12) was associated with the increased risk of intracranial bleeding in head CT scan by 20.70 (5.58-76.77) times significantly higher (p < 0.001). Conclusion: There is significant relationship between the patient's level of consciousness represented by Glasgow Coma Scale (GCS) and the intracranial bleeding based on the head CT scan in the patients with head injuries

Abstract
INTRODUCTION Traumatic brain injury (TBI) remains a leading cause of hospital admission and mortality, intracranial hemorrhage (ICH) presents a severe complication. Low complication tolerance in developed countries and risk uncertainty, often cause excessive observation, diagnostics and hospitalization, considered unnecessary and expensive. Risk factors predicting ICH, progression and death in patients hospitalized with mild TBI have not been identified yet. METHODS Mild TBI cases indicated for cranial computer tomography (CT) and hospitalization, according to international guidelines, at our Level I Trauma Center between 2008 and 2018 were retrospectively included. Multivariate logistic regression was performed for ICH, progression and mortality predictors. RESULTS 1788 mild TBI adults (female: 44.3%; age at trauma: 58.0 ± 22.7), were included. Skull fracture was diagnosed in 13.8%, ICH in 46.9%, ICH progression in 10.6%. In patients < 35 years with mild TBI, chronic alcohol consumption (p = 0.004) and skull fracture (p < 0.001) were significant ICH risk factors, whilst in patients between 35 and 65 years, chronic alcohol consumption (p < 0.001) and skull fracture (p < 0.001) revealed as significant ICH predictors. In patients with mild TBI > 65 years, age (p = 0.009), anticoagulation (p = 0.007) and neurocranial fracture (p < 0.001) were significant, independent risk factors for ICH, whilst increased age (p = 0.01) was a risk factor for mortality following ICH in mild TBI. Late-onset ICH only occurred in mild TBI cases with at least two of these risk factors: age > 65, anticoagulation, neurocranial fracture. Overall hospitalization could have been reduced by 15.8% via newly identified low-risk cases. CONCLUSIONS Age, skull fracture and chronic alcohol abuse require vigilant observation. Repeated CT in initially ICH negative cases should only be considered in newly identified high-risk patients. Non-ICH cases aged < 65 years do not gain safety from observation or hospitalization. Recommendations from our data might, without impact on patient safety, reduce costs by unnecessary hospitalization and diagnostics.

Abstract
Background Ruptured appendicitis has a high morbidity and mortality and requires immediate surgery. The Alvarado Score is used as a tool to predict the risk of acute appendicitis, but there is no such score for predicting rupture. This study aimed to develop the prediction score to determine the likelihood of ruptured appendicitis in an Asian population. Methods This study was a diagnostic, retrospective cross-sectional study in the Emergency Medicine Department of Ramathibodi Hospital between March 2016 and March 2018. The inclusion criteria were age >15 years and an available pathology report after appendectomy. Clinical factors included gender, age>60 years, right lower quadrant pain, migratory pain, nausea and/or vomiting, diarrhea, anorexia, fever>37.3°C, rebound tenderness, guarding, white blood cell count, polymorphonuclear white blood cells (PMN) > 75%, and pain duration before presentation. The predictive model and prediction score for ruptured appendicitis were developed by multivariable logistic regression analysis. Result During the study period, 480 patients met the inclusion criteria; of these, 77 (16%) had ruptured appendicitis. Five independent factors were predictive of rupture, age>60 years, fever>37.3°C, guarding, PMN>75%, and duration of pain>24 hours to presentation. A score >6 increased the likelihood ratio of ruptured appendicitis by 3.88 times. Conclusion Using the Ramathibodi Welawat Ruptured Appendicitis Score (RAMA WeRA Score) developed in this study, a score of >6 was associated with ruptured appendicitis.

Abstract
Background The majority of clinical decision rules for prediction of intracranial injury in patients with mild traumatic brain injury (TBI) were developed from high-income countries. The application of these rules in low or middle-income countries, where the primary mechanism of injury was traffic accidents, is questionable. Methods We developed two practical decision rules from a secondary analysis of a multicenter, prospective cohort of 1,164 patients with mild TBI who visited the emergency departments from 2013 to 2016. The clinical endpoints were the presence of any intracranial injury on CT scans and the requirement of neurosurgical interventions within seven days of onset. Results Thirteen predictors were included in both models, which were age ≥60 years, dangerous mechanism of injury, diffuse headache, vomiting >2 episodes, loss of consciousness, posttraumatic amnesia, posttraumatic seizure, history of anticoagulant use, presence of neurological deficits, significant wound at the scalp, signs of skull base fracture, palpable stepping at the skull, and GCS <15 at 2 hours. For the model-based score, the area under the receiver operating characteristic curve (AuROC) was 0.85 (95%CI 0.82, 0.87) for positive CT results and 0.87 (95%CI 0.83, 0.91) for requirement of neurosurgical intervention. For the clinical-based score, the AuROC for positive CT results and requirement of neurosurgical intervention was 0.82 (95%CI 0.79, 0.85) and 0.84 (95%CI 0.80, 0.88), respectively. Conclusions The models delivered good calibration and excellent discrimination both in the development and internal validation cohort. These rules can be used as assisting tools in risk stratification of patients with mild TBI to be sent for CT scans or admitted for clinical observation.

Abstract
Traumatic brain injury (TBI) is a major public health issue worldwide. A portable near-infrared spectroscopy (NIRS) is a non-invasive device to detect intracranial hematoma. The advantages of the NIRS include real time results and non-radiation exposure. However, sensitivity and specificity of the NIRS for intracranial hematoma are varied. This study aimed to evaluate the diagnostic properties of the NIRS in TBI patients to detect intracranial hematoma. This study was a diagnostic and prospective study conducted at the Emergency Department. The inclusion criteria were adult patients (age of 18 years or over) with moderate to high risk of all degrees of traumatic brain injury within 24 h after the injury. The primary endpoint of the study was a description of diagnostic properties of the NIRS compared with the CT brain. There were 47 patients enrolled in the study. Most of patients had Glasgow Coma Scale of 15 (44 patients; 93.62 %). Of those, 11 patients (23.40 %) had intracranial hematoma: subdural hematoma (n = 9), epidural hematoma (n = 1), intracerebral hematoma (n = 1), and subarachnoid hemorrhage (n = 3). One patient had subdural hematoma, epidural hematoma, intracerebral hematoma and subarachnoid hemorrhage. There were 31 patients had abnormal findings by the NIRS but only 11 patients had bleeding detected by the CT brain. There were 16 patients had negative results on both the NIRS and the CT brain. The sensitivity and specificity of the NIRS compared with the CT brain was 100 % and 44.4 %, respectively. The area under the ROC curve of the NIRS was 0.722. The median time to complete the NIRS examination was 3 min. In conclusion, the NIRS has high sensitivity and negative predictive value for intracranial hematoma detection in mild TBI patients with extra-axial hematomas.

Abstract
INTRODUCTION Emergency departments (EDs) routinely provide discharge instructions due to a large number of patients with mild traumatic brain injury (mTBI) being discharged home directly from ED. This study aims to evaluate the quality of available mTBI discharge instructions provided by EDs of Malaysia government hospitals. METHODS All 132 EDs were requested for a copy of written discharge instruction given to the patients. The mTBI discharge instructions were evaluated using the Patient Education Materials Assessment-Printable Tool (PEMAT-P) for understandability and actionability. Readability was measured using an online readability tool of Malay text. The content was compared against the discharge instructions recommended by established guidelines. RESULTS 49 articles were eligible for the study. 26 of the articles met the criteria of understandability, and 3 met the criteria for actionability. The average readability level met the ability of average adult. Most of the discharge instructions focused on emergency symptoms, and none contained post-concussion features. CONCLUSION Majority of the discharge instructions provided were appropriate for average people to read but difficult to understand and act upon. Important information was neglected in most discharge instructions. Thus, revision and future development of mTBI discharge instruction should consider health literacy demand and cognitive ability to process such information.

Validity of mild TBI risk score to predict intracranial hemorrhage in cases of mild traumatic brain injury in Thailand. Trauma Surg Acute Care Open 2020; 5:e000453. [PMID: 32377569 PMCID: PMC7199817 DOI: 10.1136/tsaco-2020-000453] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/10/2020] [Revised: 03/28/2020] [Accepted: 03/31/2020] [Indexed: 11/03/2022] Open
Abstract
BackgroundPatients with mild traumatic brain injury (TBI) will receive a brain CT scan based on risk of injury. A previous study established a scoring system for patients with mild TBI that assigned <3 points for the low-risk group, 3–6 points for the moderate-risk group, and ≥6 points for the high-risk group. The purpose of this study was to evaluate the external validity of mild TBI risk scores for predicting intracranial hemorrhage in patients with mild TBI who had been transferred to receive a brain CT scan at the 10 nationwide CT scan–capable facilities in Thailand.MethodsThe study was a retrospective cross-sectional review of patients with mild TBI who received a brain CT scan in 10 nationwide hospitals of Thailand. Risk factors were observed and points calculated for predicting mild TBI scores based on patient records. Injured patients were divided into two groups: CT scans indicating normal and abnormal brain images. After this, the accuracy of mild TBI score for predicting the presence of intracranial hemorrhage was investigated.ResultsThe study included a total of 999 patients, comprising 461 (46.15%) patients with abnormal brain CT scans indicating intracranial hemorrhage and 538 (53.85%) indicating no intracranial hemorrhage. In the low-risk group (mild TBI risk score <3), moderate-risk group (mild TBI risk score 3–6), and high-risk group (mild TBI risk score >6), the likelihood ratio positive of brain CT scans were 0.41, 3.53, and 77.3, respectively.DiscussionMild TBI risk score may assist healthcare providers to select patients with mild TBI for brain CT scan referral, particularly in hospitals without CT scan facilities. In such cases, based on the proposed scoring system, immediate transfer of moderate-risk and high-risk patients with mild TBI to a CT scan–capable facility is necessary.
