Reversing the "Risk-Treatment Paradox" of Bleeding in Patients Undergoing Percutaneous Coronary Intervention: Risk-Concordant Use of Bleeding Avoidance Strategies Is Associated With Reduced Bleeding and Lower Costs.

Background Bleeding is a common, morbid, and costly complication of percutaneous coronary intervention. While bleeding avoidance strategies ( BAS ) are effective, they are used paradoxically less in patients at high risk of bleeding. Whether a patient-centered approach to specifically increase the risk-concordant use of BAS and, thus, reverse the risk-treatment paradox is associated with reduced bleeding and costs is unknown.
