Blood transfusions are the most common procedure for hospitalized patients. Transfusion reactions occur following 1-3% of all blood transfusions. These reactions can be classified into a number of specific entities, although the distinctions between specific types of reactions are often subjective.
A collaborative working group between the CDC and AABB has developed publicly available guidelines for accurate diagnosis of transfusion reactions. While this document lists specific diagnostic criteria, it is not very user-friendly.
This application is based on a proprietary algorithm that uses the CDC/AABB criteria and a series of simple questions to readily enable even the novice user to accurately diagnose transfusion reactions to blood products.
This application is only a tool. The results should be compared against the CDC/AABB criteria. Medical decisions based on the output of this app should only be made by qualified and licensed medical providers.
