Abstract
Among nonagenarians admitted to our emergency department (ED) for ground-level falls, we assessed the impact of pre-injury antithrombotic (AT) treatment on the post-traumatic consequences, and identified risk factors for 1-month mortality. All eligible patients were consecutively included over an 18-month period. Head trauma was attested by reliable medical history, witnesses or recent external signs. Patient characteristics, post-traumatic consequences and outcomes were compared across patients with and without AT. Risk factors for 1-month mortality were assessed using multivariate logistic regression analyses. 1014 consecutive nonagenarians were analysed, 675 (66.6%) with AT and 339 (33.4%) without. Head trauma (n = 429, 42.3%) was significantly more frequent among patients with AT (49.2 vs 28.6%, p < 0.001). Intracranial hemorrhage (ICH, n = 43, 4.2%), mostly subdural hematomas (58%), were more frequently found among patients with AT (p < 0.015). At least one fracture was diagnosed for 23.9% of the population, mostly hip fractures, without any significant association with AT. At 1 month, 103 patients (10.2%) had died. The independent risk factors for 1-month mortality were: ICH associated with head trauma (OR = 5.9, 95% CI 2.5-14), Glasgow coma score ≤ 12 at admission (OR = 10; 95% CI 2.2-46), atrial fibrillation (OR = 2.2, 95% CI 1.4-3.4) and age ≥ 95 years (OR = 1.6, 95% CI 1.0-2.5). Our results support accurate and regular assessment of the benefit/risk ratio for antithrombotic treatment among elderly people at high risk for falls.

Abstract
OBJECTIVES Primary: describe characteristics of adults aged ≥65 attending the Emergency Department (ED) at one major trauma center. Secondary: examine co-morbidities and complications; identify use of anticoagulant/antiplatelet medication among older adults presenting with Head Injury (HI); assess clinical management against UK guidelines. METHODS All ED admissions were screened prospectively to identify HI using case notes, hospital records and Trauma Audit Research Network data. Data were collected on demographics, cause and severity of injury, co-morbidities, anticoagulation/antiplatelet use, diagnostic imaging and discharge outcomes. RESULTS Over 12 months, 697 patients aged ≥65 years attended the ED for HI, representing over a quarter of adult ED attendances for HI. Mean age was 78.5 years (range 65-106), 395 (56.7%) were female. Most HIs were mild (93.5%) and 86% caused by falls. Three-quarters were discharged without hospital admission. Most had a preexisting medical condition andtaking medications prior to HI. Of these 116 were taking anticoagulants/antiplatelets but only 37 (31.9%) received a head CT scan. Half the patients were given a written HI information sheet at ED discharge. CONCLUSIONS Care of HI in older adults is challenging due to comorbidities. Practising evidence-based clinical management and following guidelines is important, but strict adherence is not common practice.

"Decision tree analysis for assessing the risk of post-traumatic haemorrhage after mild traumatic brain injury in patients on oral anticoagulant therapy". BMC Emerg Med 2022; 22:47.

Abstract
BACKGROUND The presence of oral anticoagulant therapy (OAT) alone, regardless of patient condition, is an indication for CT imaging in patients with mild traumatic brain injury (MTBI). Currently, no specific clinical decision rules are available for OAT patients. The aim of the study was to identify which clinical risk factors easily identifiable at first ED evaluation may be associated with an increased risk of post-traumatic intracranial haemorrhage (ICH) in OAT patients who suffered an MTBI. METHODS Three thousand fifty-four patients in OAT with MTBI from four Italian centers were retrospectively considered. A decision tree analysis using the classification and regression tree (CART) method was conducted to evaluate both the pre- and post-traumatic clinical risk factors most associated with the presence of post-traumatic ICH after MTBI and their possible role in determining the patient's risk. The decision tree analysis used all clinical risk factors identified at the first ED evaluation as input predictor variables. RESULTS ICH following MTBI was present in 9.5% of patients (290/3054). The CART model created a decision tree using 5 risk factors, post-traumatic amnesia, post-traumatic transitory loss of consciousness, greater trauma dynamic, GCS less than 15, evidence of trauma above the clavicles, capable of stratifying patients into different increasing levels of ICH risk (from 2.5 to 61.4%). The absence of concussion and neurological alteration at admission appears to significantly reduce the possible presence of ICH. CONCLUSIONS The machine-learning-based CART model identified distinct prognostic groups of patients with distinct outcomes according to on clinical risk factors. Decision trees can be useful as guidance in patient selection and risk stratification of patients in OAT with MTBI.

Incremental Risk of Intracranial Hemorrhage After Mild Traumatic Brain Injury in Patients on Antiplatelet Therapy: Systematic Review and Meta-Analysis. J Emerg Med 2020; 59:843-855. [PMID: 33008665 DOI: 10.1016/j.jemermed.2020.07.036] [Citation(s) in RCA: 11] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/29/2020] [Revised: 07/05/2020] [Accepted: 07/19/2020] [Indexed: 02/07/2023]
Abstract
BACKGROUND Mild traumatic brain injury (TBI) is a common event and antiplatelet therapy might represent a risk factor for bleeding. OBJECTIVE The aim of this study was to evaluate the risk of intracranial hemorrhage (ICH) after mild TBI in patients on antiplatelet therapy through a systematic review and meta-analysis. METHODS We conducted a systematic review and meta-analysis of prospective and retrospective observational studies on patients with mild TBI on antiplatelet therapy vs. those not on any antithrombotic therapy. The primary outcome was the risk of ICH in patients with mild TBI based on the first computed tomography scan. Secondary outcome was the risk of mortality and neurosurgery. RESULTS Nine studies and 14,545 patients were included. The incidence of ICH ranged from 3.6% to 29.4% in the antiplatelet group and from 1.6% to 21.1% in the control group. Patients on antiplatelet therapy had a higher risk of ICH after a mild TBI compared with patients that were not on antithrombotic therapy (risk ratio 1.51; 95% confidence interval 1.21-1.88). No difference was found in the composite outcome of mortality and neurosurgery. CONCLUSIONS Patients on antiplatelet therapy have an increased risk of ICH after mild TBI compared with patients not on antithrombotic therapy. However, the risk is just slightly increased, and the need to perform a computed tomography scan in patients on antiplatelet therapy after a mild TBI should be evaluated case by case, but always considered in patients with other risk factors.
