Outcome of Patients Who Refuse Transfusion After Cardiac Surgery: A Natural Experiment With Severe Blood Conservation Outcome of Patients Who Refuse Transfusion
Jehovah's Witness patients (Witnesses) who undergo cardiac surgery provide a unique natural experiment in severe blood conservation because anemia, transfusion, erythropoietin, and antifibrinolytics have attendant risks. Our objective was to compare morbidity and long-term survival of Witnesses undergoing cardiac surgery with a similarly matched group of patients who received transfusions.
