Parent Perceptions of Emergent Blood Transfusion in Children.

BACKGROUND: RhD-negative blood products are in chronic short supply leading to renewed interest in utilizing RhD-positive blood products for emergency transfusions. This study assessed parental perceptions of emergency RhD-positive blood use in children.

METHODS: A survey of parents/guardians was conducted on their tolerance of transfusing RhD-positive blood to RhD-negative female children ≤17 years old at four level 1 pediatric hospitals.

RESULTS: In total, 621 parents/guardians were approached of whom 378/621 (61%) completed the survey in its entirety and were included in the analysis. Respondents were mostly females [295/378 (78%)], White [242/378 (64%)], had some college education [217/378 (57%)] and less than $60,000 annual income [193/378 (51%)]. Respondents had a total of 547 female children. Most children's ABO [320/547 (59%)] and RhD type [348/547 (64%)] were not known by their parents; of children with known RhD type, 58/186 (31%) were RhD-negative. When the risk of harm to a future fetus was given as 0-6%, more than 80% of respondents indicated they were likely to accept RhD-positive blood transfusions on behalf of RhD-negative female children in a life-threatening situation. The rate of willingness to accept emergent RhD-mismatched blood transfusions significantly increased as the potential survival benefit of the transfusion increased.

CONCLUSION: Most parents were willing to accept RhD-positive blood products on behalf of RhD-negative female children in an emergency situation. Further discussions and evidence-based guidelines on transfusing RhD-positive blood products to RhD-unknown females in emergency settings are needed. This article is protected by copyright.
