Abstract
Background:
Direct oral anticoagulants (DOACs) remain mostly investigational in patients with moderate to severe hepatic cirrhosis, yet are often selected over traditional anticoagulants including warfarin and enoxaparin in this setting.
Objective:
To determine the safety and efficacy of DOACs in patients with moderate to severe hepatic cirrhosis as compared with traditional anticoagulation.
Methods:
This was a retrospective, single-center cohort study evaluating inpatients and outpatients who were prescribed a DOAC, warfarin, or enoxaparin for therapeutic anticoagulation with Child-Turcotte-Pugh (CTP) B or C status at the time that the prescription was written. Included patients were followed until first bleeding or thromboembolic event, or until discontinuation of anticoagulation therapy. Data were collected by manual chart review. The primary outcomes included both bleeding events and thromboembolic events in the DOAC population as compared with traditional anticoagulation.
Results:
A total of 101 patients were included in the study, 69 treated with DOAC therapy and 32 with traditional anticoagulation. Bleeding events occurred in 36% of patients in the DOAC group and 22% of patients in the traditional group (P = 0.149). In both groups, bleeds were most commonly gastrointestinal. Thromboembolic events occurred in 4% of the DOAC population and no patients in the traditional population (P = 0.55). No fatal bleeding or thromboembolic events occurred.
Conclusion and Relevance:
DOACs do not appear to be more harmful than traditional anticoagulation in patients with CTP B or C status. These results support the use of DOACs in patients with CTP B or C hepatic cirrhosis when considering safety, efficacy, and convenience.
