Cryoprecipitate. Patterns of use.

Abstract

The type of coagulation factors and proteins in cryoprecipitate determine the appropriate indications for its use. To determine the pattern of use at a tertiary care medical center, we performed a retrospective audit of cryoprecipitate utilization. A total of 51 patients received 88 pools of cryoprecipitate. In 39 patients, cryoprecipitate was transfused for appropriate indications: hypofibrinogenemia (n = 19), tissue plasminogen activator reversal (n = 1), management of massive transfusion (n = 7), correction of uremic bleeding (n = 2), and for making fibrin sealant (n = 10). Overall, these patients used approximately 80% of the cryoprecipitate transfused. In 12 other patients, cryoprecipitate was transfused inappropriately to attempt reversal of the anticoagulant effects of warfarin therapy (n = 6), to treat impaired surgical hemostasis in the absence of hypofibrinogenemia (n = 4), and to treat hepatic coagulopathy with multiple factor deficiencies (n = 2). The patterns of misuse, involving 24% of all cryoprecipitate orders, suggest a widespread misunderstanding and need for focused education about the coagulation factors and proteins present in cryoprecipitate and appropriate indications for its use.
