Delayed hemolytic transfusion reaction in the French hemovigilance system

Area of Science:

• Transfusion Medicine
• Hematology
• Patient Safety

Background:

• Mandatory reporting of transfusion-related adverse events in France since 1993.
• The French hemovigilance system has enhanced recognition of transfusion risks.
• Delayed hemolytic transfusion reactions (DHTR) in sickle-cell disease (SCD) were previously under-reported.

Purpose of the Study:

• To highlight the role of the French hemovigilance system in recognizing DHTR in SCD patients.
• To present one of the largest series of DHTR in SCD patients.
• To describe improvements in reporting and data quality for transfusion complications.

Main Methods:

• Analysis of data collected by the French hemovigilance system.
• Dissemination of information within the hemovigilance network to improve reporting.
• Development of guidelines and specific reporting forms for DHTR.

Main Results:

• Significant improvement in the reporting of DHTR in SCD patients.
• The French hemovigilance system holds a substantial dataset on DHTR in this population.
• Enhanced data quality is anticipated with new guidelines and forms.

Conclusions:

• The French hemovigilance system plays a crucial role in identifying and managing transfusion risks like DHTR in SCD.
• Improved reporting and data quality are essential for epidemiological studies and patient safety.
• Ongoing development of guidelines and reporting tools will further strengthen hemovigilance efforts.
