Abstract
BACKGROUND: Data regarding the use of direct oral anticoagulants (DOACs) for the treatment of acute pulmonary embolism (PE) are sparse. We conducted a prospective multicentre registry study to describe patterns of DOAC prescription for the treatment of acute PE, and the associated risk of 6-month adverse events in daily practice. METHODS: We included all PE patients discharged since the availability of DOACs for the dedicated indication of acute PE treatment. Clinical data and 6-month outcomes, including death, recurrent venous thromboembolism (VTE), bleeding, and chronic thromboembolic pulmonary hypertension (CTEPH) were recorded prospectively. Temporal trends in DOAC prescription were tested. RESULTS: Between 09/2012 and 04/2017, 1082 patients were included: 60.6% (n = 656) were treated with DOACs and 39.4% (n = 426) with another anticoagulant. The prescription rate of DOACs increased sharply just after their release on the market to reach a plateau over time, between 56% and 72% of the total prescription per year in PE patients (p for trend = 0.33). Active malignancy and renal function impairment were factors independently associated with non-prescription of DOACs. Overall, prescription of DOACs was appropriate in 95.3% of patients. The rate of use of non-recommended DOAC doses was 4.2% (n = 28). The rate of death, recurrent VTE, bleeding and CTEPH were 2.4%, 1.2%, 7.2%, and 1.9%, respectively in the DOAC group. CONCLUSION: The choice to prescribe DOACs or not is related to patient characteristics. The overall appropriateness of prescription is high, while the rate of adverse events observed in patients treated with DOAC is low in our registry.
