Peridischarge prophylactic platelet transfusions after stem cell transplant: is a tranfusion trigger needed?

Area of Science:

• Hematology
• Transplant Medicine
• Oncology

Background:

• Assessing the appropriateness of peridischarge platelet (PLT) transfusions in transplant recipients.
• Evaluating the feasibility of reducing the PLT transfusion threshold before discharge.

Purpose of the Study:

• To examine the appropriateness of prophylactic PLT transfusions within 24 hours of discharge.
• To determine if lowering the PLT transfusion threshold is feasible in transplant recipients.

Main Methods:

• Retrospective review of prophylactic PLT transfusions administered within 24 hours of discharge.
• Analysis of transfusion indications and adherence to institutional guidelines.
• Identification of 187 transplant patients, with 44 receiving prophylactic PLT transfusions.

Main Results:

• Of 44 patients receiving transfusions, indications included meeting discharge PLT count (20 × 10(9)/L), central venous catheter removal, active bleeding, or anticoagulation.
• 95% of prophylactic PLT transfusions were deemed appropriate; only 5% were avoidable.
• Lowering the threshold to 15 × 10(9)/L could have avoided 41% of appropriate transfusions.

Conclusions:

• A significant portion of prophylactic PLT transfusions before discharge may be avoidable.
• A risk-adapted strategy for selecting transplant recipients for prophylactic PLT transfusions could be beneficial.
• Further research is warranted to explore risk-adapted methods for PLT transfusion management.
