Show moreBackgroundAcute alcohol intoxication is very common in patients with severe traumatic brain injury (TBI). Whether there is an independent association between alcohol intoxication and mortality is debated. This study hypothesized that alcohol intoxication is independently associated with less mortality after severe TBI (sTBI).MethodsThis retrospective observational cohort study included all patients with sTBI [head-Abbreviated Injury Score (AIS) >= 3, corresponding to serious head injury or worse] admitted from 1 January 2011 to 31 December 2016 in an academic level I trauma center. Patients were classified as with alcohol intoxication or without intoxication based on blood alcohol concentration or description of alcohol intoxication on admission. The primary endpoint was in-hospital mortality. Multivariable logistic regression analysis, including patient and injury characteristics, was used to assess independent association with alcohol intoxication.ResultsOf the 2865 TBI patients, 715 (25%) suffered from alcohol intoxication. They were younger (mean age 46 vs. 68 years), more often male (80 vs. 57%) and had a lower median Glasgow Coma Scale upon arrival (14 vs. 15) compared to the no-intoxication group. There was no difference in injury severity by head AIS or Rotterdam CT. Alcohol intoxication had an unadjusted association with in-hospital mortality [unadjusted odds ratio (OR) 0.51; 95% confidence interval (CI), 0.38-0.68]; however, there was no independent association after adjusting for potentially confounding patient and injury characteristics (adjusted OR 0.72; 95% CI, 0.48-1.09).ConclusionIn this retrospective study, there was no independent association between alcohol intoxication and higher in-hospital mortality in emergency patients with sTBI.

Show moreBackground: Patients on prehospital anticoagulation with warfarin or direct oral anticoagulants (DOACs) represent a vulnerable subset of the trauma population. While protocolized warfarin reversal is widely available and easily implemented, prehospital anticoagulation with DOAC is cost prohibitive with only a few reversal options. This study aims to compare hospital outcomes of non-head injured trauma patients taking pre-injury DOAC versus warfarin.Methods: A retrospective cohort study at a level 1 trauma center was performed. All adult trauma patients with pre-injury anticoagulation admitted between January 2015 and December 2018, were stratified into DOAC-using and warfarin-using groups. Patients were excluded if they had traumatic brain injury (TBI). Univariate and multivariable analyses were performed. Outcomes measures included inhospital mortality, blood transfusion requirements, ICU length of stay (LOS), hospital LOS and discharge disposition.Results: 374 non-TBI trauma patients on anticoagulation were identified, of which 134 were on DOACs and 240 on warfarin. Patients on DOACs had a higher ISS (9 [IQR, 9-10] vs. 9 [IQR, 5-9]; p<0.001), and lower admission INR values (1.2 [IQR, 1.1-1.3] vs 2.4 [IQR, 1.8-2.7]; p<0.001) than warfarin users. Use of reversal agents was higher in warfarin users (p< 0.001). Relative to warfarin, DOAC users did not differ significantly with respect to hospital mortality (OR 0.47, 95% CI [0.13-1.73]). Multivariable analysis (not possible for mortality) did not show significant difference for RBC transfusion requirements (OR 0.92 [0.51-1.67]), ICU LOS (OR 1.08 [0.53-2.19]), hospital LOS (OR 1.10 [0.70-1.74]) or discharge disposition (OR 0.56 [0.29-1.11]) between the groups.Conclusion: Despite lower reversal rates and higher ISS, non-TBI trauma patients with pre-injury DOAC use had similar outcomes as patients on pre-injury warfarin. There may be equipoise to have larger, prospective studies evaluating the comparative safety of DOACs and warfarin in the population prone to low energy fall type injuries. (C) 2020 Elsevier Ltd.
