Drug-drug interaction between dexamethasone and direct-acting oral anticoagulants: a nested case-control study in the national COVID cohort collaborative (N3C).
This study examined whether there is an association between thromboembolotic events (TEEs) and concomitant use of dexamethasone with either apixaban or rivaroxaban (both direct oral anticoagulants or DOACs) during treatment for COVID-19. The authors used data from the National COVID Cohort Collaborative (N3C) to conduct a nested case-control study. Eligible participants were adults over 18 years who were exposed to a DOAC for 10 or more consecutive days and exposure to dexamethasone at least 5 or more consecutive days. The study did not find a discernible association of TEE in patients concomitantly exposed to dexamethasone and a DOAC.

Shared decision-making for drug-drug interactions: formative evaluation of an anticoagulant drug interaction.
This study evaluated a tool called DDInteract that was developed to enhance and support shared decision-making (SDM) between patients and physicians when both warfarin and NSAIDs are used concurrently. The study used case vignettes with physicians and patients on warfarin to conduct simulated virtual clinical encounters where they discussed the use of taking ibuprofen and warfarin concurrently and determined an appropriate therapeutic plan based on the patient’s individualized risk. Participants completed a postsession interview and SDM process survey, including the 9-item Shared Decision-Making Questionnaire (SDM-Q-9), tool usability and workload National Aeronautics and Space Administration (NASA) Task Load Index, Unified Theory of Acceptance and Use of Technology (UTAUT), Perceived Behavioral Control (PBC) scale, System Usability Scale (SUS), and Decision Conflict Scale (DCS). A total of 12 physician-patient dyads were used, with over 91% of the patients over 50 and 75% had been taking warfarin for over 2 years. Most participants rated DDInteract higher than usual care (UC) and would be willing to use the tool for an interaction involving warfarin and NSAIDs.
