Implication

Survey study reveals widespread use of bivalirudin protocols in cardiac surgery patients with heparin-induced thrombocytopenia, highlighting guideline adoption despite practice variation.

Key Points

To characterize clinical practice patterns regarding the diagnosis and alternative anticoagulation management of patients with heparin-induced thrombocytopenia requiring cardiopulmonary bypass.
Administered an electronic survey to members of the Society of Cardiovascular Anesthesiologists and the American Society for Extracorporeal Technology.
Assessed institutional protocol utilization, diagnostic approaches, and alternative anticoagulant selection across clinical practices (N=304 respondents; 5.8% response rate).
Diagnosis relied primarily on clinical history (71%) and antibody assays (63%), with 75% of respondents utilizing an established institutional protocol for bypass cases.
Bivalirudin was the most frequently selected alternative anticoagulant (75%), and activated clotting time was used by 83% of respondents for anticoagulation monitoring across at least 785 managed cases.
