Minor head injury in anticoagulated patients: Outcomes and analysis of clinical predictors. A prospective study. Am J Emerg Med 2024; 76:105-110. [PMID: 38056055 DOI: 10.1016/j.ajem.2023.11.023] [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: 07/04/2023] [Revised: 11/01/2023] [Accepted: 11/13/2023] [Indexed: 12/08/2023] Open
Abstract
BACKGROUND The optimal management of patients taking oral anticoagulants who experience minor head injury (MHI) is unclear. The availability of validated protocols and reliable predictors of prognosis would be of great benefit. We investigated clinical factors as predictors of clinical outcomes and intracranial injury (ICI). METHODS We conducted a single-cohort, prospective, observational study in an ED. Our structured clinical pathway included a first head CT scan, 24 h observation and a second CT scan. The primary outcome was the occurrence of MHI-related death or re-admission to ED at day +30. The secondary outcome was the rate of delayed ICI (dICI), defined as second positive CT scan after a first negative CT scan. We assessed some clinical predictors derived from guidelines and clinical prediction rules as potential risk factors for the outcomes. RESULTS 450 patients with a negative first CT scan who underwent a second CT scan composed our 'study population'. The rate of the primary outcome was 4%. The rate of the secondary outcome was 4.7%. Upon univariate and multivariate analysis no statistically significant predictors for the outcomes were found. CONCLUSIONS Previous retrospective studies showed a lot of negative predictive factors for anticoagulated patients suffering a minor head injury. In our prospective study no clinical factors emerged as predictors of poor clinical outcomes and dICI. So, even if we confirmed a low rate of adverse outcomes, the best management of these patients in ED remains not so clear and future trials are needed.

Risk of both intracranial hemorrhage and ischemic stroke in elderly individuals with nonvalvular atrial fibrillation taking direct oral anticoagulants compared with warfarin: Analysis of the ANAFIE registry. Int J Stroke 2023; 18:986-995.

Abstract
BACKGROUND AND AIMS Elderly patients with nonvalvular atrial fibrillation (NVAF) might have a higher risk of intracerebral hemorrhage. To investigate this, we compared the incidence of intracranial hemorrhage (ICH) and its subtypes, as well as ischemic stroke, in patients taking direct oral anticoagulants (DOACs) compared with warfarin in a real-world setting. We also determined the baseline characteristics associated with both ICH and ischemic stroke. METHODS Patients aged ⩾ 75 years with documented NVAF enrolled in the prospective, multicenter, observational All Nippon Atrial Fibrillation in the Elderly Registry between October 2016 and January 2018 were evaluated. The co-primary endpoints were the incidence of ischemic stroke and ICH. Secondary endpoints included subtypes of ICH. RESULTS Of 32,275 patients (13,793 women; median age, 81.0 years) analyzed, 21,585 (66.9%) were taking DOACs and 8233 (25.5%) were taking warfarin. During the median 1.88-year follow-up, 743 patients (1.24/100 person-years) developed ischemic stroke and 453 (0.75/100 person-years) developed ICH (intracerebral hemorrhage, 189; subarachnoid hemorrhage, 72; subdural/epidural hemorrhage, 190; unknown subtype, 2). The incidence of ischemic stroke (adjusted hazard ratio (aHR) 0.82, 95% confidence interval (CI) 0.70-0.97), ICH (aHR 0.68, 95% CI 0.55-0.83), and subdural/epidural hemorrhage (aHR 0.53, 95% CI 0.39-0.72) was lower in DOAC users versus warfarin users. The incidence of fatal ICH and fatal subarachnoid hemorrhage was also lower in DOAC users versus warfarin users. Several baseline characteristics other than anticoagulants were also associated with the incidence of the endpoints. Of these, history of cerebrovascular disease (aHR 2.39, 95% CI 2.05-2.78), persistent NVAF, (aHR 1.90, 95% CI 1.53-2.36), and long-standing persistent/permanent NVAF (aHR 1.92, 95% CI 1.60-2.30) was strongly associated with ischemic stroke; severe hepatic disease (aHR 2.67, 95% CI 1.46-4.88) was strongly associated with overall ICH; and history of fall within 1 year was strongly associated with both overall ICH (aHR 2.29, 95% CI 1.76-2.97) and subdural/epidural hemorrhage (aHR 2.90, 95% CI 1.99-4.23). CONCLUSION Patients aged ⩾ 75 years with NVAF taking DOACs had lower risks of ischemic stroke, ICH, and subdural/epidural hemorrhage than those taking warfarin. Fall was strongly associated with the risks of intracranial and subdural/epidural hemorrhage. DATA ACCESS STATEMENT The individual de-identified participant data and study protocol will be shared for up to 36 months after the publication of the article. Access criteria for data sharing (including requests) will be decided on by a committee led by Daiichi Sankyo. To gain access, those requesting data access will need to sign a data access agreement.

Abstract
Objective To assess the accuracy of a five-step prehospital trauma triage protocol ( Échelle québécoise de triage préhospitalier en traumatologie (EQTPT)) to identify patients requiring urgent and specialized in-hospital trauma care in the Capitale-Nationale region – Québec. Methods The medical records of trauma patients transported by ambulance to one of the five participating emergency departments (EDs) between November 2016 and March 2017 were reviewed. Our primary outcome was the need for one of the following urgent and specialized trauma care: endotracheal intubation in the ED, administration of ≥ 2 blood products in the ED, angioembolization or surgery (excluding single limb surgery) < 24 h and admission to the intensive care unit (ICU) or in-hospital trauma-related death. Results A total of 902 patients were included. The median age was 63 (interquartile range (IQR) 51) and 494 (54.8%) were female. The main trauma mechanism was falls (n = 592), followed by motor vehicle accidents (n = 201). Eighty-two (9.1%) patients required at least one urgent and specialized trauma care. Of those, 44 (53.6%) were identified as requiring transport to a level one trauma centre (steps 1–3), 16 were identified as requiring transport to a centre with a lower level of trauma designation (steps 4–5) while 22 (26.8%) did not meet any of the EQTPT criteria. For steps 1 to 3, the sensitivity was 53.7% (95% confidence interval (CI) 42.9–64.4) and the specificity was 81.7% (95% CI 79.1–84.4) in identifying patients requiring specialized trauma care. Conclusion The EQTPT lacked sensitivity and was poorly specific to identify trauma patients who need specialized in-hospital trauma care.

Validation of the cutaneous impact location to predict intracranial lesion among elderly admitted to the Emergency Department after a ground-level fall. Injury 2023; 54:1306-1313. [PMID: 36841696 DOI: 10.1016/j.injury.2023.02.023] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 07/21/2022] [Revised: 01/30/2023] [Accepted: 02/10/2023] [Indexed: 02/27/2023]
Abstract
INTRODUCTION In the Emergency Departments, almost one out of two head CT scans are carried out for traumatic brain injuries among elderly victims of ground level-falls. Recently, a new predictive factor for intracranial lesions in this population has been suggested: presence and location of cutaneous impact. The aim of this study was to establish determinants of intracranial lesion among older patients admitted to EDs due to ground-level falls with traumatic brain injury using the head cutaneous impact location. METHODS A retrospective, observational and monocentric study of patients admitted to Emergency Department for ground-level falls with traumatic brain injury was carried out between 01 January 2017 and 31 July 2017. The primary outcome was identification of an acute intracranial lesion. A bootstrap procedure was employed to evaluate performance and internal validity of the final model. RESULTS Among the 1036 patients included, the mean age was 85.6 (SD 7.6) years and 94/1036 (9.1%, 95% CI 7.4-10.9) patients presented with an acute intracranial lesion. Multivariable analysis adjusted by bootstrap shrinkage showed that compared with temporal-parietal or occipital impact, Odds Ratio of intracranial lesions were 0.61 (95% CI 0.39-0.95, p = 0.03) in patients with frontal impact, 0.27 (95% CI 0.12-0.59, p = 0.001) in patients with facial impact and 0.21 (95% CI 0.06-0.77, p = 0.018) in patients without cutaneous impact. Subcutaneous hematoma (OR 1.97, p = 0.007), loss of consciousness (OR 4.66, p<0.001), fall-related amnesia (OR 2.58, p = 2.6), vomiting (OR 2.62, p = 0.002) and altered Glasgow Score (OR 6.79, p<0.001) were as well associated with high risk of intracranial lesion. Taking antiplatelets or anticoagulants were not associated with an increased risk of intracranial lesions. The model discrimination was adequate (C-statistic 0.79; 95% CI 0.73 - 0.85). CONCLUSION Our results establish specific determinants of intracranial lesions among elderly after ground level-falls. The cutaneous impact location may identify patients with high risk of intracranial lesion. Further researches are needed to propose a specific score based on these determinants so as to better target Head CT scan use.

Abstract
INTRODUCTION Elderly patients on oral anticoagulation are commonly seen in emergency departments (EDs). Oral anticoagulation, particularly warfarin, is associated with an increased risk of intracranial hemorrhage after head trauma. Data on delayed bleeds in anticoagulated patients are limited. The objective of this study was to examine risk of delayed intracranial hemorrhage in patients presenting to the ED with a head injury anticoagulated with warfarin or a direct oral anticoagulant, compared to patients not anticoagulated. METHODS Cohort study using administrative data from Ontario of patients ≥ 65 years presenting to the ED with a complaint of head injury between 2016 and 2018. The primary outcome was delayed intracranial hemorrhage, defined as a new ICD-10 code for intracranial hemorrhage within 90 days of the initial ED visit for a head injury where no intracranial hemorrhage was diagnosed. The main exposure variable was oral anticoagulation use, which was a three-level variable (warfarin, direct oral anticoagulants, or no oral anticoagulation). We used multivariable logistic regression to determine the odds of delayed intracranial hemorrhage based on anticoagulation status. RESULTS 69,321 patients were included: 58,233 (84.0%) had not been prescribed oral anticoagulation, 3081 (4.4%) had a warfarin prescription, and 8007 (11.6%) had a direct oral anticoagulant prescription. Overall, 718 (1.0%) patients had a delayed intracranial hemorrhage within 90 days of ED visit for head injury. Among patients not anticoagulated, 586 (1.0%) had a delayed intracranial hemorrhage, 54 (1.8%) patients on warfarin, and 78 (1.0%) patients on a direct oral anticoagulant had a delayed intracranial hemorrhage. There was an increased odds of delayed intracranial hemorrhage with warfarin use compared with no anticoagulation (OR 1.5, 95% CI 1.1-2.1). There was no association between delayed intracranial hemorrhage and direct oral anticoagulant use compared to no anticoagulation (OR 0.9, 95% CI 0.6-1.1). CONCLUSIONS There was an increased odds of delayed intracranial hemorrhage within 90 days in older ED head injured patients prescribed warfarin compared to patients not on anticoagulation. direct oral anticoagulant use was not associated with increased risk of delayed intracranial hemorrhage.
