Background and purpose: The incidence of non-traumatic intracranial hemorrhage (ICH) during treatment with direct oral anticoagulants (DOACs) is lower than that during warfarin treatment. The characteristics of intracranial hemorrhage during DOAC therapy, however, remain unclear. Therefore, we performed a nationwide survey in Japan to examine the clinical characteristics and outcomes of DOAC-associated ICH using data obtained from the Japanese Diagnosis Procedure Combination (DPC)-based Payment System. Methods: We analyzed the data of 1,567 patients with ICH (DOAC-associated ICH, 88; warfarin-associated ICH, 1,479) who were urgently hospitalized at 575 institutions across Japan from April 2010 to March 2013 for whom prescription data before admission were available. Results: The annual number of patients with all anticoagulant (DOAC or warfarin)- associated ICH in each year from 2010 to 2013 was 226, 252, 426, and 663, representing 15.7%, 15.4%, 16.1%, and 16.1% of all ICH cases in the same period, respectively. There was an increase in the proportion of patients who presented with DOAC-associated ICH in all anticoagulant-associated ICH in each year from 2010 to 2013 (0%→0.4%→3.8%→10.7%). The proportion of patients with impaired consciousness (three-digit score on Japan Coma Scale) at admission (DOAC, 19.3%; Warfarin, 25.4%; P=0.20), in-hospital mortality within 7 days (DOAC, 11.4%; Warfarin, 19.5%; P=0.06), and mRS score of 5-6 at discharge (DOAC, 27.3%; Warfarin, 37.4%; P=0.06) were lower in the patients with DOAC-associated ICH. The rates of surgery for hematoma removal were significantly lower in the patients with DOAC-associated ICH (NOAC, 2.3%; Warfarin, 9.7%; P=0.019). Conclusions: This is the largest nationwide study of DOAC-associated ICH in a real-world situation in Japan, revealing that the patients with DOAC-associated ICH had better clinical outcomes compared with warfarin-associated ICH, probably due to milder hemorrhage at admission.

Background Direct oral anticoagulants (DOACs) have overtaken warfarin as the preferred anticoagulants for stroke prevention with atrial fibrillation and for treatment of venous thromboembolism. Despite the increased prevalence of DOACs, literature studying their impact on trauma patients with intracranial hemorrhage (ICH) remains limited. Most DOAC reversal agents have only been recently available, and concerns for worse outcomes with DOACs among this population remain. This study aims to assess the outcomes of patients with traumatic ICH taking DOACs compared with those taking warfarin. Methods A retrospective analysis of patients with traumatic ICH over a 5-year period was conducted. Demographics, injury severity, medication, and outcome data were collected for each patient. Patients taking warfarin and DOACs were compared. Results 736 patients had traumatic ICH over the study period, 75 of which were on either DOACs (25 patients) or warfarin (50 patients). The median age of the anticoagulated patients was 78 years; 52% were female, and 91% presented secondary to a fall. DOACs were reversed at close to half the rate of warfarin (40% vs 77%; P = .032). Despite this, the 2 groups had similar rates of worsening examination, need for operative intervention, and in-hospital mortality. In the follow-up, fewer patients taking DOACs had died at 6-months postinjury compared with those taking warfarin (8% vs 30%; P = .041). Discussion Despite DOACs being reversed at nearly half the rate of warfarin, patients presenting with traumatic ICH on warfarin had higher 6-month mortality suggesting a potential survival advantage for DOACs over warfarin in this population.

Abstract Background The role of coagulopathy in patients with traumatic brain injury has remained elusive. In the present study, we aim to assess the prevalence of coagulopathy in patients with traumatic intracranial hemorrhage, their clinical features, and the effect of coagulopathy on treatment and mortality. Methods An observational, retrospective single-center cohort of consecutive patients with traumatic intracranial hemorrhage treated at Helsinki University Hospital between 01 January and 31 December 2010. We compared clinical and radiological parameters in patients with and without coagulopathy defined as drug- or disease-induced, i.e., antiplatelet or anticoagulant medication at a therapeutic dose, thrombocytopenia (platelet count < 100 E9/L), international normalized ratio > 1.2, or thromboplastin time < 60%. Primary outcome was 30-day all-cause mortality. Logistic regression analysis allowed to assess for factors associated with coagulopathy and mortality. Results Of our 505 patients (median age 61 years, 65.5% male), 206 (40.8%) had coagulopathy. Compared to non-coagulopathy patients, coagulopathy patients had larger hemorrhage volumes (mean 140.0 mL vs. 98.4 mL, p < 0.001) and higher 30-day mortality (18.9% vs. 9.7%, p = 0.003). In multivariable analysis, older age, lower admission Glasgow Coma Scale score, larger hemorrhage volume, and conservative treatment were independently associated with mortality. Surgical treatment was associated with lower mortality in both patients with and without coagulopathy. Conclusions Coagulopathy was more frequent in patients with traumatic intracranial hemorrhage presenting larger hemorrhage volumes compared to non-coagulopathy patients but was not independently associated with higher 30-day mortality. Hematoma evacuation, in turn, was associated with lower mortality irrespective of coagulopathy.

Direct oral anticoagulants (DOACs) are a new class of anticoagulants that directly inhibit either thrombin or factor Xa in the coagulation cascade. They are being increasingly used instead of warfarin or other vitamin K antagonists (VKAs). Adverse side effects of DOACs may result in hemorrhagic complications, including life-threatening intracranial hemorrhage (ICH), though to a much lesser degree than VKAs. Currently there are relatively limited indications for DOACS but their usage is certain to expand with the availability of their respective specific reversal agents. Currently, only idarucizumab (antidote for dabigatran) has been United States Food and Drug Administration- (FDA-) approved, but others (andexanet-α and ciraparantag) may be approved in near future, and the development and availability of such reversal agents have the potential to dramatically change the current anticoagulant use by providing reversal of multiple oral anticoagulants. Until all the DOACs have FDA-approved reversal agents, the treatment of the dreaded side effects of bleeding is challenging. This article is an attempt to provide an overview of the management of hemorrhage, especially ICH, related to DOAC use.
