BACKGROUND

Prothrombin complex concentrate (PCC) is widely used to reverse the action of direct oral anticoagulants (DOACs) in accordance with current guidelines and because of a lack of specific reversal agents. Indications, clinical characteristics and patient outcomes of patients might differ in comparison to reversal of vitamin K antagonists where reversal with PCC is well established.

METHODS

Our cohort study explores patient characteristics, indications and clinical outcomes for reversal of all DOAC patients receiving PCC at our university emergency department from 01.06.2012 to 01.07.2017, in comparison with patients on VKA.

RESULTS

Out of 199,982 consultations, we studied 346 patients who were given PCC for reversal of either DOAC (n = 74) or VKA (n = 272). The most common reason for treatment was acute bleeding; in 86.7% of both groups. 37.3% of bleeding was traumatic (p = 0.666). The most frequent bleeding location was intracranial (61.6%, p = 0.881). Gastrointestinal bleeding was more often found in the DOAC group (18.9% vs. 8.8%, p = 0.014). More erythrocyte concentrates (ECs) were given to DOAC patients with blood transfusion (p = 0.014). Tranexamic acid was used more often in DOAC patients than in VKA patients (28.4% vs. 7.4%, p < 0.001). No significant group differences were found for the following patient outcomes: in-hospital mortality, ICU stay, and length of stay at the ICU or in hospital.

CONCLUSION

In DOAC treated patients, PCC was applied more often because of gastrointestinal bleeding and patients received higher numbers of ECs as well as tranexamic acid. No differences were observed with regard to important clinical outcomes.
