To analyze platelet transfusion practices and factors influencing posttransfusion platelet increments in neonates and children.
Approach:
Key Findings:
3.6% of encounters involved at least one platelet transfusion.
Transfusion rates were lowest in children <1 year (2.6%) and highest in those aged 1 to <6 years (4.7%).
67.8% of neonates received transfusions at platelet counts >25 × 10^3/μL.
81.0% of older children received transfusions at counts >10 × 10^3/μL.
Factors like PAS, PR, and longer storage were linked to lower posttransfusion increments.
Interpretation:
Platelet transfusion practices vary significantly, with specific donor and product factors influencing transfusion outcomes and frequency. Decisions should be based on clinical context rather than solely on platelet increment targets.
Limitations:
Retrospective design limits causal inference.
Inability to determine exact transfusion indications.
Post hoc definitions of bleeding may affect results.
Limited adjustment for illness severity.
Conclusion:
The study underscores the need for a nuanced approach to platelet transfusion in pediatric populations, considering both clinical context and variability in transfusion practices.
