Physician compliance with platelet usage criteria.

Area of Science:

• Hematology
• Transfusion Medicine
• Clinical Pathology

Background:

• Platelet transfusions are critical for managing bleeding in thrombocytopenic patients.
• However, transfusions carry inherent risks and significant costs.
• Appropriate allocation of platelet units is essential for patient safety and resource management.

Purpose of the Study:

• To assess physician adherence to established platelet transfusion criteria.
• The study focused on a tertiary care academic institution.

Main Methods:

• Retrospective review of 282 platelet unit releases over four months.
• Analysis of pretransfusion platelet counts and reasons for transfusion via chart review and clinician interviews.
• Determination of compliance with institutional platelet transfusion guidelines.

Main Results:

• 11% (32 of 282) of platelet transfusions did not meet established criteria.
• Justifiable exceptions included bleeding risks (oral ulcers, pre-discharge) and antiplatelet use in cardiac surgery.
• Unjustified transfusions occurred in a lung cancer patient (110 x 10(3)/microL) and four septic patients (70-90 x 10(3)/microL).

Conclusions:

• Physician compliance with platelet transfusion criteria reached 89%.
• Transfusion medicine specialists deemed strict adherence inapplicable for 9.2% of cases.
• A small percentage (1.8%) of platelet transfusions were deemed unnecessary, preventable by expert intervention.
