At the conclusion of this educational activity, the participant should be able to:
1) Define heparin-induced thrombocytopenia (HIT)
2) Describe the study design/analysis – the vast majority of patients with HIT did not received plasma exchange
3) Explain the main findings: no mortality difference, possible association of plasma exchange with bleeding risk and higher hospital length of stay. This may have been due to sicker patients being more likely to receive plasma exchange.
