Assessing the impact of a heparin-induced thrombocytopenia protocol on patient management, outcomes and cost.

Establishing the diagnosis of heparin induced thrombocytopenia (HIT) is challenging as laboratory tests for HIT vary in specificity and availability. As HIT suspicion far exceeds confirmation of diagnosis, overtreatment is an emerging concern. This pilot study evaluated the impact of a HIT Recognition and Management Protocol on direct thrombin inhibitor (DTI) prescribing, outcomes, and cost.
