Platelet Transfusions in a Multi-Neonatal Intensive Care Unit Health Care Organization Before and After Publication of the PlaNeT-2 Clinical Trial.

To evaluate whether implementing more restrictive neonatal intensive care unit (NICU) platelet transfusion guidelines following the Platelets for Neonatal Transfusion - Study 2 randomized controlled trial (transfusion threshold changed from 50 000/μL to 25 000/μL for most neonates) was associated with fewer NICU patients receiving a platelet transfusion, without adversely affecting outcomes. Multi-NICU retrospective analysis of platelet transfusions, patient characteristics, and outcomes during 3 years before vs 3 years after revising system-wide guidelines. During the first period, 130 neonates received 1 or more platelet transfusions; this fell to 106 during the second. The transfusion rate was 15.9/1000 NICU admissions in the first period vs 12.9 in the second (P = .106). During the second period, a smaller proportion of transfusions was administered when the platelet count was in the 50 000-100 000/μL range (P = .017), and a larger proportion when it was <25 000/μL (P = .083). We also saw a fall in the platelet counts that preceded the order for transfusion from 43 100/μL to 38 000/μL (P = .044). The incidence of adverse outcomes did not change. Changing platelet transfusion guidelines in a multi-NICU network to a more restrictive practice was not associated with a significant reduction in number of neonates receiving a platelet transfusion. The guideline implementation was associated with a reduction in the mean platelet count triggering a transfusion. We speculate that further reductions in platelet transfusions can safely occur with additional education and accountability tracking.
