- 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 < 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.
- 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 analysis
