Abstract

Aims: The management of patients treated with direct oral anticoagulants (DOACs) during hospitalization is a common challenge in clinical practice. Although bridging is generally not recommended, too often DOACs are switched to parenteral therapy with low molecular weight heparins. Our objectives were to update a local guideline for perioperative DOAC management and to develop a guideline for the anticoagulation management in non-surgical patients regarding temporary DOAC discontinuation.

Methods: We executed a two-step modified Delphi study in a 1000-bed university hospital in Belgium. The Delphi questionnaires were developed based on a literature review and a telephone survey of prescribers. Two expert panels were established: one dedicated to perioperative DOAC management and the other to DOAC management in non-surgical patients. Both panels completed two rounds, commencing with an individual and online round, followed by a face-to-face group session.

Results: After the two-round Delphi process, the updated perioperative guideline on DOAC management included reasons for delaying the resumption of DOACs following surgery, such as oral intake not possible, the probability of re-intervention within 3 days, and insufficient haemostasis (e.g. active clinically significant haematoma, haemorrhagic drains or wounds). Furthermore, a guideline for non-surgical hospitalized patients was developed, outlining possible reasons for interrupting DOAC therapy. Both guidelines offer clear anticoagulation therapy strategies corresponding to the identified scenarios.

Conclusions: We have updated and developed guidelines for DOAC management in surgical and non-surgical patients during hospitalization, which aim to support prescribers and to enhance targeted prescription review by hospital pharmacists.
