Implication

Health system analysis demonstrates reduced unnecessary serotonin release assays in suspected heparin-induced thrombocytopenia, indicating stewardship improves diagnostic testing efficiency.

Key Points

Anticoagulation stewardship substantially optimizes serotonin release assay ordering by curbing unnecessary testing among patients with negative platelet factor 4 antibody results.
Hospital testing dropped to 3.4% under stewardship compared to 24.4% without oversight, confirming reduced serotonin release assay ordering for antibody-negative patients.
Analysis of health system laboratory records highlights reflex thresholding for heparin-induced thrombocytopenia, while small validation cohorts warrant ongoing performance monitoring.
