Barriers to continued administration of direct oral anticoagulants between acute hospital and subacute or chronic hospitals and geriatric health services facilities in Japan

Abstract

ABSTRACT Objectives: To investigate whether direct oral anticoagulant (DOAC) therapy at acute hospitals is continued after transfer to subacute or chronic hospitals and geriatric health services facilities in Japan. Methods: Acute hospitals routinely transfer patients to nearby subacute or chronic hospitals and geriatric health services facilities after acute stroke treatment. To elucidate the status of antithrombotic therapy, particularly DOAC therapy, we conducted a questionnaire survey of chief physicians at 33 subacute or chronic hospitals and geriatric health services facilities in the vicinity of Kawasaki City. Results: Responses were received from 23 hospitals and geriatric health services facilities (5 convalescent and rehabilitation hospitals, 5 chronic hospitals, 13 geriatric health services facilities). The number of convalescent hospitals responding, ‘no problem with DOAC administration’ before transfer to subacute or chronic hospitals and geriatric health services facilities increased from 4 (80%) at the introduction of DOACs to 5 (100%) presently. The number of chronic hospitals and geriatric health services facilities also increased from 1 (20%) to 3 (60%) and 4 (30.8%) to 5 (38.5%), respectively, albeit not significantly. The number of convalescent hospitals, chronic hospitals, and geriatric health services facilities requesting pre-transfer change of oral anticoagulants decreased from 20% to 0%, 60% to 40%, and 69.2% to 61.5%, respectively. All convalescent hospitals continued DOAC therapy after transfer. However, only 40.0% of chronic hospitals and 46.2% of geriatric health services facilities used DOACs in the present period. Warfarin was used instead at 3 (60%) chronic hospitals and 7 (53.8%) geriatric health services facilities and antiplatelet drugs were used at 1 hospital/facility each (20% and 7.7%, respectively). Nine (39.1%) hospitals and facilities cited high DOAC costs for the switch. Conclusions: Convalescent hospitals have incorporated DOAC use and readily accept patients receiving DOACs at transferring hospitals. Conversely, many chronic hospitals and geriatric health services facilities eventually switch from DOACs to warfarin or antiplatelet drugs due to cost. Efforts to resolve these barriers to continued administration of DOACs between acute hospitals and subacute or chronic hospitals and geriatric health services facilities in Japan are needed as soon as possible.
