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.

Low anti-factor Xa level predicts 90-day symptomatic venous thromboembolism in surgical patients receiving enoxaparin prophylaxis: a pooled analysis of eight clinical trials.
This study examined whether low anti-factor Xa (aFXa) level predicts 90-day symptomatic venous thromboembolism (VTE) in surgical patients receiving enoxaparin prophylaxis. The authors conducted a pooled analysis of 8 clinical trials from a single institution over a 4-year period. Among 985 patients, 2.3% had symptomatic 90-day VTE, 4.2% had 90-day clinically relevant bleeding, and 2.1% had major bleeding. Patients with initial low aFXa were significantly more likely to have 90-day VTE than patients with adequate or high xFXa (4.2% vs 1.3%). This relationship was significant for patients who received enoxaparin twice daily as opposed to once a day. No association was seen between high xFXa and 90-day clinically relevant bleeding or major bleeding.

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.

Warfarin monitoring in safety-net health systems: analysis by race/ethnicity and language preference.
This study’s objective was to determine if there were any race/ethnicity or language disparities in warfarin monitoring in safety-net systems using differences in international normalized ratio (INR) monitoring. This cross-section analysis used process and safety data shared from the Safety Promotion Action Research and Knowledge Network (SPARK-Net) initiative, a consortium of five California safety-net hospital systems. A total of 8129 patients were included: 3615 (44%) were female; 1470 (18%), Black/African American; 3354 (41%), Hispanic/Latinx; 1210 (15%), Asian; 1643 (20%), White; and 452 (6%), other. A total of 45% were non-English preferring. The authors did not observe statistically significant disparities in the rate of appropriate INR monitoring by race/ethnicity or language. The primary source of variation was by healthcare network.

Management of patients on anticoagulants and antiplatelets during acute gastrointestinal bleeding and the peri-endoscopic period: a clinical practice guideline dissemination tool.
The American College of Gastroenterology and the Canadian Association of Gastroenterology jointly created recommendations on the management of anticoagulants and antiplatelets during acute gastrointestinal (GI) bleeding and the elective per-endoscopic period. The clinical practice guideline (CPG) panel was restricted in making strong recommendations regarding some relevant clinical questions because of the limited certainty of evidence in the literature. The purpose of this paper was to describe a clinical practice guideline dissemination tool for the management of patients on anticoagulants and antiplatelets during acute gastrointestinal bleeding and the peri-endoscopic period. The dissemination tool addresses provider concerns about limited certainty of evidence in the literature by providing clinicians with a companion piece to execute recommendations with contextual guidance and practical algorithms. The patient’s risks of a thromboembolic event versus the procedural risk of GI bleeding is taken into account in the implementation of the tool. The authors concluded that the clinical practice guideline dissemination tool provides both contextual information in interpreting the clinical guideline panel’s recommendations and algorithmic guidance for common scenarios encountered during endoscopic practice.

Lessons learned from the historical trends on thrombolysis use for acute ischemic stroke among Medicare beneficiaries in the United States.
The authors’ objectives were to assess and validate the change in intravenous thrombolysis (IVT) utilization in a national sample of Medicare beneficiaries and to examine the effect of patient, stroke center designation, and geography on IVT utilization. They found that, between 2007 and 2014, the frequency of IVT for patients with acute ischemic stroke increased substantially, though differences persisted in the form of less frequent treatment associated with certain characteristics.

Implementing an electronic health record dashboard for safe anticoagulant management: learning from qualitative interviews with existing and potential users to develop an implementation process.
This study examined the implementation of electronic dashboards and the key barriers that were found. Semi-structured interviews were conducted at the national Veterans Health Affairs (VA) following implementation of a population health tool, and in Michigan for the Michigan Anticoagulation Quality Improvement Initiative (MAQI(2) dashboard tool designed for pharmacist or nurse use to monitor safe outpatient anticoagulant prescribing by physicians and other clinicians. A total of 45 stakeholders were interviewed, 32 at the VA, and 13 at MAQI(2). Five key determinants of implementation success were identified: (1) clinician authority and autonomy, (2) clinician self-identity and job satisfaction, (3) documentation and administrative needs, (4) staffing and work schedule, and (5) integration with existing information systems. Key differences between the two contexts included concerns about IT support and prioritization within MAQI(2) prior to implementation but not VHA after implementation and also concerns about authority and autonomy.
