Abstract
The role of transfusion medicine consultative services in prospectively auditing (PA) orders for four-factor prothrombin complex concentrate (4F-PCC) was evaluated at an academic medical center. Data from 4 years of 4F-PCC orders were obtained from the laboratory information system, and electronic health records of patients receiving concentrate were reviewed. 4F-PCC was ordered for 427 patients with warfarin-, apixaban-, or rivaroxaban-associated hemorrhage. Turnaround time (TAT) to prepare 4F-PCC was longer when PA-recommended dose adjustments were needed (85 vs 66 minutes, P = .03). There was no difference in TAT between patients who died and those who were ultimately discharged (60 vs 70, P = .22). TAT was shortest for orders originating in the emergency department (ED) compared with other locations (64 vs 85, P < .001), and ED TAT was not associated with patient outcomes in ED patients. PA and dose adjustments reduced amounts of concentrate issued by 27 IU per dose (P = .01). Median international normalized ratio less than 1.3 after 4F-PCC transfusion was achieved for all anticoagulants after dose adjustments. PA did not affect order cancellation or product wastage rates. PA can ensure 4F-PCC is dosed appropriately without affecting patient outcomes.
