Heparin Induced Thrombocytopenia: Pharmacoeconomics

Patients at BWH receiving unfractionated heparin or enoxaparin who subsequently develop heparin induced thrombocytopenia will be identified via a computer generated report designed for the purposes of this study. Subsequently, we will compare the heparin induced thrombocytopenia rates associated with heparin and low molecular weight heparin usage as well as evaluate the economic and long-term clinical burden of heparin induced thrombocytopenia.
