Evaluation of Heparin-Induced Thrombocytopenia Antibody Laboratory Use and Anticoagulation Prescribing Patterns

Introduction Heparin-induced thrombocytopenia (HIT) is a rare adverse reaction Calculating a 4T score prior to ordering a heparin-PF4 immunoassay is recommended. For a score \u3c 4, HIT probability is low and an assay is not advised If high suspicion of HIT (4T greater than or equal to 4), an assay should be ordered, all heparin products discontinued, and a non-heparin anticoagulant initiated. Purpose Determine if heparin immunoassay ordering was indicted according to retrospective 4T score Assess anticoagulation prescribing depending on the result of the assay Serve as a pre-group for a planned perverse post-HIT order set implementation analysishttps://digitalcommons.centracare.com/pharmacy_posters/1007/thumbnail.jp
