Development of a risk prediction model for transfusion in carotid endarterectomy and demonstration of cost-saving potential by avoidance of type and screen

摘要

ObjectivesPreoperative testing for carotid endarterectomy (CEA) often includes blood typing and antibody screen (T&S). In our institutional experience, however, transfusion for CEA is rare. We assessed transfusion rate and risk factors in a national clinical database to identify a cohort of patients in whom T&S can safely be avoided with the potential for substantial cost savings.
