Learning Objectives

After participating in this educational activity, participants should be able to:

  • List current AABB criteria for culturing residual components in the setting of suspected septic transfusion reaction.
  • Discuss variation in transfusion reaction reporting and culturing rates between institutions.
  • Apply modified criteria to decision-making about when to culture residual units to improve sensitivity for positive results.

Program Description

In the setting of a suspected septic transfusion reaction, current AABB criteria can guide the decision-making process about when to culture residual units. However, these criteria as currently defined have some limitations. This program will present data from the SCARED study, a multicenter retrospective study which assessed institutional variability in residual unit and patient culturing practices and the yield of various approaches. Modified criteria are proposed which will improve the sensitivity of detecting a positive culture.
