2025 Imagine - P153 - Warfarin and Hospital Stay: “A Clot” of Unwanted Time - On Demand
This session analyzes the impact of warfarin use on the length of stay (LOS) and blood transfusion rates of cardiac surgery patients, using data from WVU Medicine and the Vizient Clinical Data Base. Findings indicate warfarin is associated with significant increases in LOS and blood use, raising concerns about the fairness of current quality metrics. Attendees will gain a deeper understanding of the clinical implications of warfarin therapy, particularly for hospitals struggling with an international normalized ratio (INR) greater than five in warfarin management. This session is crucial for healthcare professionals seeking to optimize anticoagulation practices in cardiac surgery.
