In this multicenter, donor-product-recipient linked cohort study, after excluding patients with bleeding, most transfusions among neonates and older children were at high pretransfusion platelet counts. Use of PAS, PR, longer storage duration, male donors, and donor age older than 40 years were independently associated with lower posttransfusion platelet increments. Use of PAS, PR, platelet storage longer than 3 days, and donor age 40 years or older were associated with a significantly higher overall platelet transfusion burden but were not associated with hospital length of stay or mortality. These results have important implications for transfusion practices for platelets among neonates and children and need validation in well-designed prospective studies.
