How do we implement pathogen reduction technology, while maintaining an adequate platelet inventory for our patients?

Abstract

Despite the significantly reduced infectious disease risk through robust and sensitive laboratory assays, comprehensive donor screening and good manufacturing practices, new and emerging infectious agents and bacterial contamination continue to pose a threat to the blood supply. Pathogen Reduction (PR) technology is an option to mitigate the risk of platelet transfusion transmitted infections. Here we describe our structure and strategies to implement PR technology. Pre-implementation and phased approach implementation processes from our hospital-based donor center, components processing laboratory, transfusion service, clinicians, nursing, and patient perspectives are described. Communication and reassessment of collection settings occurred between the donor center and components processing laboratory (CPL). During Phase 1, CPL consistently processed approximately 56% of monthly apheresis platelets (AP) collections by PR and the remaining 44% as conventional platelets (CP). Phase 2 increased the amount of AP undergoing PR from 56% to approximately 78%. A phased implementation and maintenance of a dual inventory may provide flexibility to blood collection, blood manufacturing, and transfusion service processes. Our dual inventory of PR and CP allows our transfusion service a readily available platelet inventory. A collaborative hospital-based donor center, component processing laboratory, and transfusion service are essential to the productivity and maintenance of the dual platelet inventory.
