Le Guide d'utilisation des anticoagulants oraux directs a été réalisé par des professionnels de la santé (médecins, pharmacien(ne)s et infirmières) oeuvrant dans des Centres Universitaires de la région de Québec. Il se veut un ouvrage de référence pratique et facile à consulter pour tous les professionnels (généralistes, spécialistes, pharmacien(ne)s et infirmier(ère)s) qui sont impliqués dans le suivi des patients pour lesquels un anticoagulant oral direct (dabigatran (Pradaxa md), rivaroxaban (Xarelto md), apixaban (Eliquis md) ou edoxaban (Lixiana md)) a été prescrit. Le guide fourni de l'information sur les indications et les critères de remboursements, les posologies (dont l'ajustement en insuffisance rénale), les précautions et contre-indications, les paramètres pharmacocinétiques, les interactions, la gestion péri et post-opératoire, la gestion des saignements, ainsi que les recommandations sur le suivi des patients. Des calculatrices utiles pour le calcul de la clairance à la créatinine ainsi que pour les échelles de risque CHADS₂, CHA₂DS₂VASC et HAS-BLED ont été intégrées afin de faciliter la prise en charge du patient. L'utilisateur doit toutefois prendre en considération que le guide a d'abord été créé par et pour les professionnels de la santé des Centres Universitaires de la région de Québec avec les particularités propres à leurs milieux spécialisés. L'utilisation du guide doit faire l'objet d'adaptations en fonction du milieu et du jugement clinique. L'application du Guide d’utilisation des AODs est une réalisation de Effenti inc.
