To review pharmacokinetic and pharmacodynamic drug-drug interactions (DDIs) involving new oral anticoagulants for atrial fibrillation. ⋯ Awareness of drugs that alter the function of the P-gp efflux transporter protein and CYP3A4 enzymes and provide additive effects should enable prescribers to anticipate and avoid potential DDIs involving the new oral anticoagulants. To this end, briefing documents and prescribing information have applied cautionary measures for individuals treated with these newer anticoagulants.

Medication-related harm can be detected using the adverse drug event (ADE) trigger tool and the medication module of the Global Trigger Tool (GTT) developed by the Institute for Healthcare Improvement (IHI). In recent years, there has been some controversy on the performance of this method. In addition, there are limited data on the performance of the medication module of the GTT as compared with the ADE trigger tool. ⋯ Applying the trigger tool method proposed by the IHI to a Belgian hospital led to the identification of one ADE out of 4 admissions. To increase performance, refining the list of triggers in the ADE trigger tool and in the medication module of the GTT would be needed. Recording nontriggered events should be encouraged.
