Abstract T P57: Length of Stay and Hospital Charges in Japanese NVAF Inpatients with Acute Stroke/TIA: The SAMURAI-NVAF Study

Purpose: Warfarin needs several days to reach the steady anticoagulative state, however novel oral anticoagulants (NOACs) does not. It may cause differences in acute hospital stay for stroke and hospital charges between NVAF patients taking warfarin and those taking NOACs. We aimed to determine the association of OAC choice after stroke with length of hospital stay and hospital charges from a multicenter prospective registry (the SAMURAI-NVAF, NCT01581502) involving 18 hospitals. Methods: 634 acute ischemic stroke/TIA survivors with NVAF (277 women, 77±10 years old) who was taking OACs at discharge between Sep 2011 and Jun 2013 were studied; three NOACs were approved for clinical use in NVAF patients in Japan just before or during the periods (dabigatran in Jan 2011, rivaroxaban in Jan 2012, apixaban in Dec 2012). Hospital charges were analyzed using 217 patients in the first author’s hospital where the Diagnosis Procedure Combination, a Japanese diagnosis-dominant case-mix system was used for charges. Re...
