The study investigates multimorbidity in view of the occurrence of two different therapeutic conflicts or dilemma situations, respectively. The first concerns patients with diagnosis of gastrointestinal bleeding and prescription of anticoagulants or/and antiplatelet drugs (e.g., warfarin, clopidogrel and acetylsalicylic acid) as a risk factor for bleeding events. The second concerns patients with diagnosis of exacerbated diabetes mellitus and prescription of corticosteroids as a risk factor for worsening of blood glucose.
