Blood transfusion is the most common procedure performed in hospitals in the U.S. Yet published evidence shows significant gaps in clinicians' knowledge of this critical aspect of patient care, including possible adverse reactions that can occur after blood transfusion. James Stubbs, M.D.; Daryl Kor, M.D.; and Justin Kreuter, M.D., offer five steps for improving the safety and efficacy of the transfusion-medicine practice.
