Abstract
OBJECTIVES We aimed to develop and validate a simple scoring system to predict in-hospital mortality after endoscopic variceal ligation (EVL) for esophageal variceal bleeding. METHODS Data from a 13-year study involving 46 Japanese institutions were split into development (initial 7 years) and validation (last 6 years) cohorts. The study subjects were patients hospitalized for esophageal variceal bleeding and treated with EVL. Variable selection was performed using least absolute shrinkage and selection operator regression, targeting in-hospital all-cause mortality as the outcome. We developed the Hospital Outcome Prediction following Endoscopic Variceal Ligation (HOPE-EVL) score from β coefficients of multivariate logistic regression and assessed its discrimination and calibration. RESULTS The study included 980 patients: 536 in the development cohort and 444 in the validation cohort. In-hospital mortality was 13.6% and 10.1% for the respective cohorts. The scoring system used five variables: systolic blood pressure (<80 mmHg: 2 points), Glasgow Coma Scale (≤12: 1 point), total bilirubin (≥5 mg/dL: 1 point), creatinine (≥1.5 mg/dL: 1 point), and albumin (<2.8 g/dL: 1 point). The risk groups (low: 0-1, middle: 2-3, high: ≥4) in the validation cohort corresponded to observed and predicted mortality probabilities of 2.0% and 2.5%, 19.0% and 22.9%, and 57.6% and 71.9%, respectively. In this cohort, the HOPE-EVL score demonstrated excellent discrimination ability (area under the curve [AUC] 0.890; 95% confidence interval [CI] 0.850-0.930) compared with the Model for End-stage Liver Disease score (AUC 0.853; 95% CI 0.794-0.912) and the Child-Pugh score (AUC 0.798; 95% CI 0.727-0.869). CONCLUSIONS The HOPE-EVL score practically and effectively predicts in-hospital mortality. This score could facilitate the appropriate allocation of resources and effective communication with patients and their families.

Development and validation of a model to predict the need for artificial airways for acute trauma patients in the emergency department: a retrospective case-control study. BMJ Open 2024; 14:e081638. [PMID: 38889944 PMCID: PMC11191793 DOI: 10.1136/bmjopen-2023-081638] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/03/2023] [Accepted: 06/05/2024] [Indexed: 06/20/2024] Open
Abstract
OBJECTIVE To develop scores for predicting the need for artificial airway procedures for acute trauma patients in the emergency department (ED). DESIGN Retrospective case-control. SETTING A tertiary comprehensive hospital in China. PARTICIPANTS 8288 trauma patients admitted to the ED within 24 hours of injury and who were admitted from 1 August 2012 to 31 July 2020. PRIMARY AND SECONDARY OUTCOME MEASURES The study outcome was the establishment of an artificial airway within 24 hours of admission to the ED. Based on the different feature compositions, two scores were developed in the development cohort by multivariable logistic regression. The predictive performance was assessed in the validation cohort. RESULTS The O-SPACER (Oxygen saturation, Systolic blood pressure, Pulse rate, Age, Coma Scale, Eye response, Respiratory rate) score was developed based on the patient's basic information with an area under the curve (AUC) of 0.85 (95% CI 0.80 to 0.89) in the validation group. Based on the basic information and trauma scores, the IO-SPACER (Injury Severity Score, Oxygen saturation, Systolic blood pressure, Pulse rate, Age, Coma Scale, Eye response, Respiratory rate) score was developed, with an AUC of 0.88 (95% CI 0.84 to 0.92). According to the O-SPACER and IO-SPACER scores, the patients were stratified into low, medium and high-risk groups. According to these two scores, the high-risk patients were associated with an increased demand for artificial airways, with an OR of 40.16-40.67 compared with the low-risk patients. CONCLUSIONS The O-SPACER score provides risk stratification for injured patients requiring urgent airway intervention in the ED and may be useful in guiding initial management. The IO-SPACER score may assist in further determining whether the patient needs planned intubation or tracheotomy early after trauma.

Abstract
BACKGROUND The Japan Coma Scale (JCS) is the most frequently adopted method for evaluating level of consciousness in Japan. However, no validated method for converting the JCS to the Glasgow Coma Scale (GCS) exists. The aims of the present study were to develop and validate a method to convert the JCS to GCS. METHODS This is a multicenter retrospective analysis involving three emergency departments (EDs) in Japan. We included all adult patients who visited the ED between 2017 and 2020. The participating facilities were divided into two cohorts-one cohort to develop a table to convert the JCS to GCS (development cohort), and the other cohort to validate the conversion table (validation cohort). The conversion table of the JCS to GCS was developed based on the median values of the GCS. The outcome was the concordance rate between the JCS and GCS. RESULTS We identified 8,194 eligible patients. The development cohort included 7,373 patients and the validation cohort included 821 patients. In the validation cohort, the absolute and relative concordance rates were 80.3% (95% confidence interval, 77.4-82.9%) and 93.2% (95% confidence interval, 91.2-94.8%), respectively. CONCLUSION This study developed and validated a novel method for converting the JCS to GCS. Assuming the offset by a single category between the JCS and GCS is acceptable, the concordance rate was over 90% in the general adult patient population visiting the ED. The conversion method may assist researchers to convert JCS scores into GCS scores, which are more commonly recognized among global audiences.

In-hospital recurrence and functional outcome between ischemic stroke caused by intracranial arterial dissection and intracranial atherosclerosis: Retrospective cohort study of the nationwide multicenter registry. J Stroke Cerebrovasc Dis 2023; 32:107212. [PMID: 37331251 DOI: 10.1016/j.jstrokecerebrovasdis.2023.107212] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2022] [Revised: 06/04/2023] [Accepted: 06/06/2023] [Indexed: 06/20/2023] Open
Abstract
BACKGROUND Intracranial arterial dissection (ICAD) and intracranial atherosclerotic stenosis (ICAS) are often difficult to differentiate, and studies on their background factors and prognosis are scarce. Information on prognosis, including recurrence, is necessary for stroke care, and clarification of epidemiological and clinical differences between the two diseases is important for appropriately handling their heterogeneity. This study aimed to determine the association of ICAD and ICAS with in-hospital recurrence and prognosis and compare their background and clinical findings. METHODS In this multicenter cohort study, we retrospectively analyzed data from the Saiseikai Stroke Database. Adults with ischemic stroke caused by ICAD or ICAS were included in this study. Patients' backgrounds and clinical findings were compared between the ICAD and ICAS groups. The outcome showed an association of ICAD with in-hospital recurrence of ischemic stroke and poor functional outcome relative to ICAS. Multivariable logistic regression analyses were performed to calculate the adjusted odds ratios (ORs) for ICAD with 95% confidence intervals (CIs) for each outcome. RESULTS Among 15,622 patients registered in the Saiseikai Stroke Database, 2,020 were enrolled (ICAD group: 89; ICAS group: 1,931). In the ICAD group, 65.2% of the patients were aged <64 years. Vascular lesion location was more common in ICAD with the vertebral artery [42 (47.2%)], anterior cerebral artery [20 (22.5%)], and middle cerebral artery (MCA) [16 (18.0%)], and in ICAS with MCA 1046 (52.3%). Multivariable logistic regression analyses of the association between ICAD and in-hospital recurrence and poor functional outcome yielded a crude OR (95% CI) of 3.26 (1.06-9.97) and 0.97 (0.54-1.74), respectively, relative to ICAS. CONCLUSION ICAD was associated with a higher in-hospital recurrence than ICAS; however, there was no significant difference in prognosis between the two groups. Differences in background characteristics and vessel lesions may be of interest in these two diseases.

Abstract
The difficulty of accurately identifying patients who would benefit from promising treatments makes it challenging to prove the efficacy of novel treatments for traumatic brain injury (TBI). Although machine learning is being increasingly applied to this task, existing binary outcome prediction models are insufficient for the effective stratification of TBI patients. The aim of this study was to develop an accurate 3-class outcome prediction model to enable appropriate patient stratification. To this end, retrospective balanced data of 1200 blunt TBI patients admitted to six Japanese hospitals from January 2018 onwards (200 consecutive cases at each institution) were used for model training and validation. We incorporated 21 predictors obtained in the emergency department, including age, sex, six clinical findings, four laboratory parameters, eight computed tomography findings, and an emergency craniotomy. We developed two machine learning models (XGBoost and dense neural network) and logistic regression models to predict 3-class outcomes based on the Glasgow Outcome Scale-Extended (GOSE) at discharge. The prediction models were developed using a training dataset with n = 1000, and their prediction performances were evaluated over two validation rounds on a validation dataset (n = 80) and a test dataset (n = 120) using the bootstrap method. Of the 1200 patients in aggregate, the median patient age was 71 years, 199 (16.7%) exhibited severe TBI, and emergency craniotomy was performed on 104 patients (8.7%). The median length of stay was 13.0 days. The 3-class outcomes were good recovery/moderate disability for 709 patients (59.1%), severe disability/vegetative state in 416 patients (34.7%), and death in 75 patients (6.2%). XGBoost model performed well with 69.5% sensitivity, 82.5% accuracy, and an area under the receiver operating characteristic curve of 0.901 in the final validation. In terms of the receiver operating characteristic curve analysis, the XGBoost outperformed the neural network-based and logistic regression models slightly. In particular, XGBoost outperformed the logistic regression model significantly in predicting severe disability/vegetative state. Although each model predicted favorable outcomes accurately, they tended to miss the mortality prediction. The proposed machine learning model was demonstrated to be capable of accurate prediction of in-hospital outcomes following TBI, even with the three GOSE-based categories. As a result, it is expected to be more impactful in the development of appropriate patient stratification methods in future TBI studies than conventional binary prognostic models. Further, outcomes were predicted based on only clinical data obtained from the emergency department. However, developing a robust model with consistent performance in diverse scenarios remains challenging, and further efforts are needed to improve generalization performance.

Abstract
OBJECTIVE It remains unclear which factors contribute to dysphagia recovery after an acute stroke. This study aimed to identify factors associated with complete oral intake recovery in patients with post-stroke dysphagia. METHODS Data were obtained from the Diagnosis Procedure Combination database, which is a nationwide database of administrative claims and discharge abstracts in Japan. We selected patients admitted within 3 days of stroke onset and conducted multivariable logistic regression analysis. Total oral intake within 30 days of admission was the primary outcome measure. RESULTS A total of 151,302 patients were included, and total oral intake was observed in 48% of them within 30 days of admission. Total oral intake was significantly associated with age, sex, stroke subtype, consciousness disturbance, low body mass index, multiple comorbidities, and the modified Rankin Scale before stroke onset. In addition, males had worse outcomes than females (odds ratio, 0.75; 95% confidence interval, 0.73-0.77, p < 0.001), and intracerebral and subarachnoid hemorrhagic stroke subtypes were associated with non-recovery. CONCLUSION This study identified several prognostic factors for total oral intake in patients with acute stroke. These results may be useful for predicting a patient's dysphagia prognosis at the time of admission and designing a nutritional management plan for patients with acute stroke.

The association between age and vital signs documentation of trauma patients in prehospital settings: analysis of a nationwide database in Japan. BMC Emerg Med 2022; 22:165. [PMID: 36195850 PMCID: PMC9531500 DOI: 10.1186/s12873-022-00725-2] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/19/2022] [Accepted: 09/26/2022] [Indexed: 11/27/2022] Open
Abstract
Background Emergency medical service (EMS) providers are the first medical professionals to make contact with patients in an emergency. However, the frequency of care by EMS providers for severely injured children is limited. Vital signs are important factors in assessing critically ill or injured patients in the prehospital setting. However, it has been reported that documentation of pediatric vital signs is sometimes omitted, and little is known regarding the performance rate of vital sign documentation by EMS providers in Japan. Using a nationwide data base in Japan, this study aimed to evaluate the relationship between patients’ age and the documentation of vital signs in prehospital settings. Methods This study was a secondary data analysis of the Japan Trauma Data Bank. The inclusion criterion was patients with severe trauma, as defined by an Injury Severity Score ≥ 16. Our primary outcome was the rate of recording all four basic vital signs, namely blood pressure, heart rate, respiratory rate, and level of consciousness in the prehospital setting among different age groups. We also compared the prehospital vital sign completion rate, that is, the rate at which all four vital signs were recorded in a prehospital setting based on age groups. Multivariate analysis was performed to evaluate factors associated with the prehospital vital sign completion rate. Results We analyzed 75,777 severely injured patients. Adults accounted for 94% (71400) of these severely injured patients, whereas only 6% of patients were children. The rate of prehospital recording of vital signs was lower in children ≤5 years than in adult patients for all four vital signs. When the adult group was used as a reference, the adjusted odds ratios of vital sign completion rate in infants (0 years), younger children (1–5 years), older children (6–11 years), and teenagers (12–17 years) were 0.09, 0.30, 0.78, and 0.87, respectively. Conclusions Analysis of the nationwide trauma registry showed that younger children tended to have a lower rate of vital sign documentation in prehospital settings.

BMC Emerg Med 2022; 22:160. [PMID: 36109716 PMCID: PMC9479253 DOI: 10.1186/s12873-022-00718-1] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/20/2022] [Accepted: 09/09/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
The outcome of road traffic injury (RTI) is determined by duration of prehospital time, patient’s demographics, and the type of injury and its mechanism. During the emergency medical service (EMS) prehospital time interval, on-scene time should be minimized for early treatment. This study aimed to examine the factors influencing on-scene EMS time among RTI patients.
Methods
We evaluated 19,141 cases of traffic trauma recorded between April 2014 and March 2020 in the EMS database of the Nara Wide Area Fire Department and the prehospital database of the emergency Medical Alliance for Total Coordination of Healthcare (e-MATCH). To examine the association of the number of EMS phone calls until hospital acceptance, age ≥65 years, high-risk injury, vital signs, holiday, and nighttime (0:00–8:00) with on-scene time, a generalized linear mixed model with random effects for four study regions was conducted.
Results
EMS phone calls were the biggest factor, accounting for 5.69 minutes per call, and high-risk injury accounted for an additional 2.78 minutes. Holiday, nighttime, and age ≥65 years were also associated with increased on-scene time, but there were no significant vital sign variables for on-scene time, except for the level of consciousness. Regional differences were also noted based on random effects, with a maximum difference of 2 minutes among regions.
Conclusions
The number of EMS phone calls until hospital acceptance was the most significant influencing factor in reducing on-scene time, and high-risk injury accounted for up to an additional 2.78 minutes. Considering these factors, including regional differences, can help improve the regional EMS policies and outcomes of RTI patients.

Abstract
OBJECTIVES This study aimed to investigate the effectiveness and safety of early mobilization with a physiatrist and registered therapist Operating rehabilitation (PROr) for patients with stroke and severe disturbance of consciousness (DoC). MATERIALS AND METHODS We retrospectively screened records from patients with stroke admitted to our hospital from January 2015 to June 2021. Eligible patients with severe DoC were classified into two groups: patients who received standard rehabilitation (control group) and patients who received PROr (PROr group). We studied longitudinal change in the level of consciousness using the Japan Coma Scale (JCS) during hospital stay and compared in-hospital mortality, the incidence of respiratory complication, and modified Rankin Scale of discharge between the two groups. RESULTS Among the 2191 patients screened for inclusion, 16 patients were included in the PROr group, and 12 patients were included in the control group. Early mobilization was more promoted in the PROr group compared to the control group, but there were no significant differences in in-hospital mortality, the incidence of respiratory complication, or modified Rankin Scale at discharge between the two groups. In patients who survived during their hospital stay, JCS scores 2 weeks after the onset of stroke and JCS scores at discharge significantly improved from the start of rehabilitation in the PROr group, but not in the control group. CONCLUSIONS Early mobilization provided with the PROr program appears to be a safe treatment and may contribute to the improvement of consciousness level for patients with acute stroke and severe DoC.

Effect of decreased tongue pressure on dysphagia and survival rate in elderly people requiring long-term care. J Dent Sci 2022; 17:856-862. [PMID: 35756815 PMCID: PMC9201529 DOI: 10.1016/j.jds.2021.09.031] [Citation(s) in RCA: 9] [Impact Index Per Article: 4.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 09/21/2021] [Indexed: 12/11/2022] Open
Abstract
Background/purpose Tongue pressure plays an important role in swallowing function. The purpose of this study is to investigate whether decreased tongue pressure is associated with dysphagia and the development of pneumonia in the elderly requiring long-term care. Materials and methods Tongue pressure measurement and swallowing videoendoscopic (VE) examination were performed in 60 hospitalized elderly people (33 males and 27 females, with an average age of 84.3 years) to investigate the relationship with the clinical course. Factors related with dysphagia was analyzed by Fisher's exact test and one-way ANOVA, followed by multivariate logistic regression. The relationship between each variable and survival were analyzed by cox regression. Results Twenty-one patients had dysphagia by VE examination. Multivariate analysis showed that smaller BMI and reduced tongue pressure were significantly correlated with dysphagia. Smaller number of remaining teeth and dysphagia were significantly related to pneumonia-related death. No patients with tongue pressure of larger than 20 kpa died by pneumonia within one year, while in those with tongue pressure of smaller than 20 kpa, one-year cumulative survival rate by pneumonia was 44.3%. Conclusion Decreased tongue pressure was significantly associated with dysphagia and may increase the risk of pneumonia-related death in the elderly requiring long-term care.

Abstract
Aim This study aimed to investigate the association between level of impaired consciousness and severe hypothermia (<28°C) and to evaluate the association between level of impaired consciousness and inhospital mortality among accidental hypothermia patients. Methods This was a multicenter retrospective study using the J‐Point registry database, which includes data regarding patients whose core body temperature was 35.0°C or less and who were treated as accidental hypothermia in emergency departments between April 1, 2011 and March 31, 2016. We estimated adjusted odds ratios of the level of impaired consciousness for severe hypothermia less than 28°C and inhospital mortality using a logistic regression model. Results The study included 505 of 572 patients in the J‐Point registry. Relative to mildly impaired consciousness (Glasgow Coma Scale [GCS] 13–15), the adjusted odds ratios for severe hypothermia less than 28°C were: moderate (GCS 9–12), 3.26 (95% confidence interval [CI], 1.69–6.25); and severe (GCS < 9), 4.68 (95% CI, 2.40–9.14). Relative to mildly impaired consciousness (GCS 13–15), the adjusted odds ratios for inhospital mortality were: moderate (GCS9–12), 1.65 (95% CI, 0.95–2.88); and severe (GCS < 9), 2.10 (95% CI, 1.17–3.78). Conclusion The level of impaired consciousness in patients with accidental hypothermia was associated with severe hypothermia and inhospital mortality.

Validation of the Japan Coma Scale for the prediction of mortality in children: analysis of a nationwide trauma database. WORLD JOURNAL OF PEDIATRIC SURGERY 2022; 5:e000350. [DOI: 10.1136/wjps-2021-000350] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/15/2021] [Accepted: 12/10/2021] [Indexed: 11/04/2022] Open
Abstract
ObjectiveThe Japan Coma Scale (JCS) is widely used in clinical practice to evaluate levels of consciousness in Japan. There have been several studies on the usefulness of JCS in adults. However, its usefulness in evaluating children has not been reported. Therefore, this study aimed to assess the usefulness of the JCS for the prediction of mortality in children.MethodsThis is a multicenter cohort study which used data from a national trauma registry (Japan Trauma Data Bank). This study included patients under 16 years of age who were treated between 2004 and 2015.The primary outcome measure was in-hospital mortality. Two models were used to examine each item of the Glasgow Coma Scale (GCS) and the JCS. Model A included the discrete levels of each index. In model B, data regarding age, sex, vital signs on arrival to hospital, the Injury Severity Score, and blunt trauma were added to each index. The effectivity of the JCS score was then evaluated using the area under the curve (AUC) for discrimination, a calibration plot, and the Hosmer-Lemeshow test for calibration.ResultsA total of 9045 patients were identified. The AUCs of the GCS and JCS were 0.929 (95% confidence interval (CI) 0.904 to 0.954) and 0.930 (95% CI 0.906 to 0.954) in model A and 0.975 (95% CI 0.963 to 0.987) and 0.974 (95% CI 0.963 to 0.985) in model B, respectively. The results of the Hosmer-Lemeshow test were 0.00 (p=1.00) and 0.00 (p=1.00) in model A and 4.14 (p=0.84) and 8.55 (p=0.38) in model B for the GCS and JCS, respectively.ConclusionsWe demonstrated that the JCS is as valid as the GCS for predicting mortality. The findings of this study indicate that the JCS is a useful and relevant tool for pediatric trauma care and future research.

Abstract
Background Tracheal intubation may be performed in patients with drug overdose due to self-harm; however, the details of the causative drug are unknown. The purpose of this study was to clarify the relationship between drugs or its blood levels of patients with drug overdose and the need for tracheal intubation based on the actual measurement results. Methods From October 2018 to March 2020, 132 patients with drug overdose due to self-harm who were transported to the emergency department (ED) were studied. Patient drugs were measured using gas chromatography–mass spectrometry (GC-MS) and were analyzed on the basis of the GC/MS Forensic Toxicological Database. Logistic analysis was performed by combining patient information and GC-MS information. Results The Glasgow Coma Scale (GCS) and Japan Coma Scale (JCS) efficiently predicted tracheal intubation in patients with drug overdose during transport triage; GCS (cut-off value: 12, area under the curve (AUC): 0.81, 95% confidence interval (CI): 0.71–0.88, sensitivity: 0.85, specificity: 0.71, P < 0.05) and JCS (cut-off value: 3, AUC: 0.74, 95% CI: 0.60–0.84, sensitivity: 0.60, specificity: 0.84, P < 0.05). The drugs detected in all patients with drug overdose in order were benzodiazepine receptor agonists (BZs; 43.9%), anticonvulsants (38.6%), antipsychotics (25.0%), and antidepressants (9.8%). In univariate logistic analysis, antipsychotics (odds ratio (OR) 2.46, 95% CI 1.19–5.20, P < 0.05), anticonvulsants (OR 2.71, 95% CI 1.26–5.98, P < 0.05), and anticonvulsants above alert blood levels (OR 27.8, 95% CI 2.92–264.1, P < 0.05) were significantly associated with tracheal intubation in patients with drug overdose, but not BZs and antidepressants. Also, in multivariate logistic analysis, antipsychotics (OR 2.27, 95% CI 1.07–4.83, P < 0.05), anticonvulsants (OR 2.50, 95% CI 1.14–5.64, P < 0.05) and in multivariate logistic analysis of blood levels, anticonvulsants above the alert blood levels (OR 24.9, 95% CI 2.56–241.6, P < 0.05) were significantly associated with tracheal intubation in patients with drug overdose respectively. Conclusions Logistic analysis revealed that the use of anticonvulsants and antipsychotics were significantly associated with an increased OR in the tracheal intubation of patients with drug overdose due to self-harm.

Abstract
Introduction: We retrospectively investigated prognostic factors for severe abdominal trauma patients evacuated by a physician-staffed helicopter emergency medical service (HEMS) and ground ambulance using the Japan Trauma Data Bank (JTDB). Methods: The study period was from January 2004 to May 2019. The subjects were divided into two groups, according to the type of outcome: the Mortality group, which included patients who ultimately died, and the Survival group, which included patients who obtained a survival outcome. Results: There were 2457 in the Mortality group and 11,326 in the Survival group. When variables that showed statistical significance in the univariate analysis were included in a multivariate analysis, the following variables were identified as significant positive predictors of a fatal outcome: evacuation from the scene, blunt injury, injury severity score, and age; significant negative predictors of a fatal outcome were transportation by the HEMS and revised trauma score. Conclusions: The present study described the usefulness of the HEMS for severe abdominal trauma patients in comparison with ground ambulance transportation using the JTDB.

Abstract
Objective: The authors retrospectively investigated prognostic factors for
severe isolated head trauma in patients evacuated by a physician-staffed helicopter
emergency medical service (HEMS) or ground ambulance using data from the Japan Trauma Data
Bank (JTDB). Patients and Methods: This study was a retrospective analysis of data housed
in the JTDB database. The study period was from January 2004 to May 2019. Subjects were
divided into two groups according to the method of transportation: helicopter (i.e.,
HEMS), which included patients transported by a physician-staffed helicopter; and
ambulance, which included patients transported by ground ambulance. Results: A total of 41,358 patients were enrolled in the study, including
2,029 in the helicopter group and 39,329 in the ambulance group. The ratio of males,
median head Abbreviated Injury Scale and Injury Severity Scale (ISS) scores were
significantly greater in the helicopter group than in the ambulance group, while the
average age, median Glasgow Coma Scale, average Revised Trauma Score (RTS), and survival
rate were significantly lower in the helicopter group than in the ambulance group. Of the
variables that demonstrated statistical significance in the univariate analysis and
classification of transportation and included in the multivariate analysis, the following
were identified as significant predictors of survival outcomes: younger age, lower ISS,
female sex, and greater RTS. HEMS was not a significant predictor of survival. Conclusion: The present study revealed no effect of HEMS transport on the
outcomes of patients who experienced severe isolated head trauma compared with ground
ambulance transportation. Further prospective studies, including an analysis of the
operation time or distance traveled by the HEMS and the functional outcome(s) of patients
with severe head injury transported by HEMS, are warranted.

Abstract
BACKGROUND We evaluated the association between D-dimer (DD) levels and long-term neurological prognoses among patients with isolated traumatic brain injury. METHODS Using data from multiple centers in the Japanese Neurotrauma Data Bank, we conducted an observational retrospective cohort study. Patients with isolated traumatic brain injury (head Abbreviated Injury Scale score > 2; any other Abbreviated Injury Scale score < 3) who were registered in the Japanese Neurotrauma Data Bank from 2015 to 2017 were recruited. We excluded patients younger than age 16 years and those who developed cardiac arrest at hospital admission. We also excluded patients with unknown Glasgow Outcome Scale (GOS) scores at 6 months after injury and those with unknown DD levels. The primary outcome was the association of DD levels with GOS scores at 6 months. We defined GOS scores 1 to 3 as poor and GOS scores 4 and 5 as good. The secondary outcome was the association of DD levels with mortality at 6 months after injury. We conducted multivariate logistic regression analyses to calculate the adjusted odds ratios of DD levels at hospital admission and GOS scores at 6 months as tertiles with 95% confidence intervals (CIs). A total of 293 patients were enrolled (median age 67 years; interquartile range 51-79 years). The median DD level was 27.1 mg/L (interquartile range 9.7-70.8 mg/L), and 58.0% (n = 170) had poor GOS scores at 6 months. RESULTS The multivariable logistic regression analysis indicated that the adjusted odds ratios were 2.52 (95% CI 1.10-5.77) for middle DD levels with poor GOS scores at 6 months and 5.81 (95% CI 2.37-14.2) for high DD levels with poor GOS scores at 6 months. CONCLUSIONS We revealed an association between DD levels and poor long-term neurological outcomes among patients with isolated traumatic brain injury.

Abstract
Aim We aimed to evaluate effect of prehospital intravenous (IV) access on mortality in traumatic shock using a large nationwide dataset. Methods We used the Japan Trauma Data Bank to identify adults (≥18 years) with a systolic blood pressure <90 mm Hg at the trauma scene and were directly transported to the hospital between 2010 and 2019. We compared patients who had prehospital IV access (IV (+)) or not (IV (−)), using propensity score‐matched analysis, and 1:1 nearest‐neighbor matching without replacement. Standardized mean difference was used to evaluate the match balance between the two matched groups; a standardized mean difference >0.1 was considered a significant imbalance. Primary outcome was 72‐h mortality. Results Propensity scores matching generated 479 pairs from 5,857 patients. No significant between group differences occurred in 72‐h mortality (7.8 versus 8.8%; difference, −1.0%; 95% confidence interval [CI]: −2.5–4.5%), 28‐day mortality (11.8 versus 11.3%; 95% CI: −4.6–3.6%), blood transfusion administration within 24 h (55.3 versus 49.1%; 95% CI: −0.1–12.6%), prehospital time (56.3 versus 53.0 min; 95% CI: −1.8–8.4 min), and cardiopulmonary arrest on hospital arrival (1.3 versus 1.3%; 95% CI: −1.4–1.4%). However, significantly higher systolic blood pressure on hospital arrival was found in the IV (+) than in the IV (−) group (104.6 versus 100.1 mm Hg; 95% CI: 0.3‐8.7 mm Hg). Conclusion We found no significant effect of establishing IV access in the prehospital setting on survival outcomes of patients with traumatic shock.

Abstract
PURPOSE The aim of this study was to assess the association between the implementation of abdominal angiography and outcome among pediatric patients with blunt splenic or hepatic injury. METHODS This was a retrospective observational study, with a study period of 14 years, from January 2004 to December 2017. Blunt-trauma patients with splenic or hepatic injury who were less than 19 years old were included in this study. We used propensity-score-(PS) matching analysis to assess the relationship between abdominal angiography and in-hospital mortality. RESULTS In total, 639 patients were eligible for analysis, with 257 patients included in the abdominal-angiography group and 382 patients in the no-abdominal-angiography group. After PS matching, 224 patients from each group were selected. In the PS matched patients, in-hospital mortality was lower in the abdominal-angiography group than in the no-abdominal-angiography group (4.9% vs. 11.2%, odds ratio 0.416, 95% confidence interval 0.177-0.903). CONCLUSION In this population, the implementation of abdominal angiography was significantly associated with lower in-hospital mortality among pediatric patients with blunt splenic or hepatic injury compared with nonimplementation of abdominal angiography.

Abstract
BACKGROUND Safe blood pressure levels in the prehospital setting for patients with traumatic brain injury (TBI) remain unclear. We aimed to investigate the association between prehospital blood pressure and the outcomes of patients with TBI to determine optimal threshold for hypotension that could be considered in the prehospital setting. METHODS Using data from the Japan Trauma Data Bank, we identified adult patients (aged ≥18 years) who experienced severe TBI (maximum head Abbreviated Injury Severity score ≥3) and were transported directly from the scene of the blunt trauma occurrence to the hospital, between 2004 and 2019. We excluded patients with prehospital systolic blood pressure (SBP) levels of <60 and ≥160 mm Hg. Using mixed effects logistic regression models, we investigated the association between prehospital SBP and in-hospital mortality, considering the hospital ID as a random effect variable. In addition, we also conducted a stratified analysis based on age (<60 vs. ≥60 years). RESULTS A total of 34,175 patients (16,114 aged <60 years and 18,061 aged ≥60 years) were eligible for the analyses. Plotting the adjusted odds ratios for in-hospital mortality as a function of SBP produced J-shaped curves. An SBP <110 mm Hg was significantly associated with in-hospital mortality, with an adjusted odds ratio of 1.52 (95% confidence interval: 1.39-1.65). Stratified analyses revealed that the threshold did not differ between the age groups. CONCLUSIONS An SBP <110 mm Hg in the prehospital setting is significantly associated with higher in-hospital mortality.

PARTICIPANTS Paediatric trauma patients <16 years old who were transferred directly from the scene of injury to the hospital and registered in the JTDB from January 2004 to December 2017 were included. We excluded patients >16 years old and those who developed cardiac arrest before or on hospital arrival. PRIMARY OUTCOME The association between BT on hospital arrival and in-hospital mortality. We conducted multivariate logistic regression analyses to calculate the adjusted ORs, with their 95% CIs, of the association between BT and in-hospital mortality. RESULTS A total of 9012 patients were included (median age: 9 years (IQR, 6.0-13.0 years), mortality: 2.5% (mortality number was 226 in total 9012 patients)). In the multivariate logistic regression analysis, the corresponding adjusted ORs of BT <36.0°C and BT ≥37.0°C, relative to a BT of 36°C-36.9°C, for in-hospital mortality were 2.83 (95% CI: 1.85 to 4.33) and 0.93 (95% CI: 0.53 to 1.63), respectively. CONCLUSIONS In paediatric patients with hypothermia (BT <36.0°C) on hospital arrival, a clear association with in-hospital mortality was observed; no such association was observed between higher BT values (≥37.0°C) and outcomes.

The associations of the number of medications and the use of anticholinergics with recovery from tubal feeding: a longitudinal hospital-based study. BMC Geriatr 2020; 20:373. [PMID: 32993523 PMCID: PMC7526129 DOI: 10.1186/s12877-020-01778-3] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/05/2020] [Accepted: 09/17/2020] [Indexed: 01/22/2023] Open
Abstract
Background Several medications, such as anticholinergics, are considered to affect the swallowing function adversely; however, whether or not anticholinergics or polypharmacy should be avoided to prevent eating dysfunction in elderly populations remains unclear. We therefore examined whether or not the number of medications or the use of anticholinergics was associated with recovery from tubal feeding in elderly inpatients. Methods We conducted a retrospective 1-year observation study in 95 Japanese hospitalized patients (83.3 ± 9.7 years old) receiving nutrition through a feeding tube. The anticholinergic cognitive burden scale (ACBs) was used as an index for quantifying the anticholinergic action. Results Thirty-six (37.9%) subjects recovered from tubal to oral feeding during the observation period. The logistic regression models showed that an increased number of prescribed medications and an increase in ACBs decreased the incidence of recovery from tubal feeding (odds ratio [95% confidence interval]: 0.66 [0.50–0.87], P = 0.003 and 0.52 [0.29–0.92], P = 0.024, respectively). Furthermore, the cumulative incidence of recovery from tubal feeding was significantly lower in the subjects who were given an additional ≥3 medications during the observation period than in those who were not (hazard ratio [95% confidence interval]: 0.08 [0.01–0.59], P = 0.014). Conclusions The findings of this study suggest that an increased exposure to medications, especially anticholinergics, may be an important factor interfering with recovery from tubal feeding in hospitalized elderly patients.

Abstract
PURPOSE We retrospectively investigated prognostic factors for severe thoracic trauma patients evacuated by a physician-staffed helicopter emergency medical service (HEMS) and ground ambulance using the Japan Trauma Data Bank (JTDB). METHODS This study was a retrospective analysis of the JTDB database. The study period was from January 2004 to May 2019. The subjects were divided into two groups, according to the type of transportation: the Heli group included cases transported by the HEMS, while the Ambulance group included cases transported by ground ambulance. RESULTS During the investigation period, a total of 57,872 patients were enrolled as subjects, including 7238 in the Heli group and 50,634 in the Ambulance group. The average age, male ratio, average injury severity score (ISS), average revised trauma score (RTS) and survival ratio were significantly greater in the Heli group than in the Ambulance group. After performing a propensity score-matched analysis, there were no statistical differences concerning the age, sex, ISS, RTS between the two groups. However, the survival ratio in the Heli group remained greater than that in the Ambulance group. When variables that showed statistical significance in the univariate analysis were included in a multivariate analysis, the RTS, transport by the HEMS, age, ISS and female gender were identified as significant predictors of a survival outcome. The HEMS was significantly associated with an increased survival ratio (odds ratio: 1.69; 95% confidence interval: 1.51-1.88) compared with a ground ambulance. CONCLUSION The present study showed that transport by the HEMS improved the survival rate compared to that by a ground ambulance for patients with severe thoracic trauma.

Abstract
OBJECTIVE We retrospectively investigated the actual conditions of burn patients evacuated by helicopter in comparison to those evacuated by ground ambulance using the Japan Trauma Data Bank. METHODS This study was a retrospective analysis of the data recorded in the Japan Trauma Data Bank between January 2004 and May 2019. After propensity score matching for the method of transportation, the survival rate was compared between the 2 groups. RESULTS During the investigation period, there were 4,627 burn patients (helicopter group, n = 276; ambulance group, n = 4,351). After propensity score matching, there were no significant differences between the 2 groups in any of the assessed variables, and the survival rate did not differ to a statistically significant extent. CONCLUSION After propensity score matching, the survival rate of the helicopter group did not appear to be superior to the ambulance group. Further prospective studies are needed to explore the proper indications for air transportation of burn patients, which could potentially improve outcomes.
