Cost of Purchased Versus Produced Plasma from Donor Recruitment Through Transfusion

Background Plasma is used to treat acquired coagulopathy or thrombotic thrombocytopenic purpura, or to reverse warfarin effect. Scant data are available, however, about its costs. Objective To estimate total costs of plasma from production through administration, from the perspective of a US hospital blood donor center (BDC). Study Design and Methods Six sequential decision analytic models were constructed and informed by primary and secondary data on time, tasks, personnel, and supplies for donation, processing, and administration. Expected values of the models were summed to yield the BDC’s total cost of producing, preparing, and transfusing plasma. Costs ($US 2015) are reported for a typical patient using three units of plasma. Models assume plasma was obtained from whole blood donation and transfused in an inpatient setting. Univariate sensitivity analyses were performed to test the impact of changing inputs for personnel costs and adverse event (AE) rates and costs. Results BDC production cost of plasma was $91.24/patient ($30.41/unit), a $30.16/patient savings versus purchased plasma. Administration and monitoring costs totaled $194.64/patient. Sensitivity analyses indicated that modifying BDC personnel costs during donation and processing has little impact on total plasma costs. However, the probability and cost of transfusion-associated circulatory overload (TACO) have a significant impact on costs. Conclusion Plasma produced by our BDC may be less costly than purchased plasma. Though plasma processes have multiple tasks involving staff time, these are not the largest cost driver. Major plasma-related AEs are uncommon, but are the biggest driver of total plasma costs.
