ReviewA narrative review of red blood cell distribution width as a marker for pulmonary embolism.
Red blood cell distribution width (RDW) is a marker of variability in red blood cell size, and is routinely reported as part of a patient's complete blood count. RDW has been shown to be associated with the prediction, severity and prognosis of pulmonary embolism (PE) in recent studies. ⋯ Nevertheless, the comparison of current studies is limited due to the definition of high RDW (each study uses a different RDW cutoff level), the broad range of exclusion criteria and the inclusion of differing modalities used to diagnose a PE (computed tomography angiogram, ventilation-perfusion study, or clinical diagnosis). Despite the above limitations, these studies provide a promising future clinical use for RDW as a marker of PE.

Assessing patient preferences for switching from warfarin to direct oral anticoagulants.
Warfarin remains the most commonly prescribed oral anticoagulant in the United States, but it has disadvantages such as dietary interactions and frequent laboratory monitoring. Direct oral anticoagulants (DOACs) have been introduced as safer and equally effective alternatives to warfarin. This study assessed patient preference for warfarin or DOAC based on a willingness to pay more for potential DOAC benefits. ⋯ Many patients currently taking warfarin preferred to stay on warfarin when given the choice, despite DOAC benefits. Willingness to pay extra for DOAC advantages did not exceed $20 in the majority of survey respondents. Previous DOAC exposure influences patient preference and perceived value for DOACs.
