AbstractIn the last decade, direct oral anticoagulants (DOACs) have entered the clinical practice of different specialists for the prevention of cardioembolic stroke in patients with non-valvular atrial fibrillation (NVAF) and the prevention and treatment of venous thromboembolism (VTE). Owing to the persistent uncertainties about the use of DOACs in daily clinical scenarios not fully explored in the clinical trials, we conducted a national Delphi consensus regarding issues deemed interesting by the Italian Atherosclerosis, Thrombosis and Vascular Biology (ATBV) Study Group in relation to: (i) elderly and/or frail patients; (ii) chronic kidney disease; (iii) drug-drug interactions; (iv) lower doses and safety; (v) criteria for choosing individual drugs and compliance; (vi) VTE in the cancer patient. Eighty-four Italian clinicians (cardiologists, internists, geriatricians, neurologists and hematologists) expressed their level of agreement on each statement using a 5-point Likert scale (1: very much in disagreement, 2: disagreement, 3: partial agreement, 4: agreement, 5: very much in agreement). In particular, 1-2 selections were considered as disagreement, while 3-5 selections were considered as agreement. A ≥66% agreement between the participants for each statement was considered consensus. In general, a broad and general awareness and sharing of the methods of use of DOACs emerged from our initiative, and in particular their preferential indication in the elderly population and in frail patients or with renal insufficiency or oncological, always following the prescription indications and dose reduction criteria. The importance of being aware of drug-drug interactions has also been underlined in a concordant way, as well as simplicity of treatment in the multi-treated patient. In view of the persistent, albeit limited (12%), absence of consensus on some issues, with regard to the frail patient, drug-food interactions and availability of antidote, the acquisition of further evidence and a persistent educational effort are nonetheless indicated.
