[Thromboembolic vein disease (TVD): antithrombotic therapy choice in ASL TO3.]

Thromboembolic vein disease (TVD) comprises of deep vein thrombosis (DVT) and pulmonary embolism (PE). Standard therapy consists of the administration of low molecular weight heparin (LMWH) imbricated with antivitamin K agonists (AVK). Recently a new series of oral anticoagulants known as the direct oral anticoagulants (DOACs) has been introduced. CHEST 2016 guidelines recommend the use of DOACs rather then AVKs for the treatment of TVD.

The aim of this study was to analise the choice of antithrombotic treatment and to see if CHEST 2016 guidelines were used in the ASL TO3 district for TVD therapy.

Data obtained from the SISR archives was used to perform a cohort retrospective study. Patients who had been recovered for TEVD were selected 6 months after dismissal. Based on Chest guidelines, the period that ranged from 01/01/2014 to 30/06/2017 was divided into two parts. The cohort was classified according to antithrombotic therapy administered to these patients.

475 patients that had been dismissed after recovery for TVD were identified and enrolled into this study. 1st period: from 275 patients, 247 had a prescription: 132 TAO, 73 DOACs, 42 eparine, 0 ASA. 2nd period: from 200 patients, 185 had a prescription: 55 TAO, 95 DOACs, 34 eparine, 1 ASA.

Our analysis shows a significant difference between the choice of antithrombotic therapy during both periods, this difference is greater among males. We can conclude that antithrombotic prescriptions carried out in the ASL TO3 area have been adherent to Chest guidelines.
