Most platelet transfusions are prophylactic. Previously, higher platelet-count thresholds were recommended for neonates, but this recommendation has been questioned in recent studies. In the PlaNeT2 trial, mortality and serious bleeding were more frequent in neonates with the highest platelet-count threshold than in others. Following this trial, we changed our platelet transfusion practice by lowering the platelet-count threshold for prophylactic transfusion from 50,000 to 25,000\/mm<jats:sup>3<\/jats:sup>. We conducted a before\u2013after retrospective cohort study to quantify the frequency of platelet transfusions and assess the new protocol by analyzing death and serious hemorrhage events. This retrospective monocentric study included neonates born before 37\u00a0weeks of gestation with platelet count\u2009&lt;\u2009150,000\/mm<jats:sup>3<\/jats:sup> during the 2\u00a0years preceding the new platelet transfusion protocol (high prophylactic transfusion threshold, 50,000\/mm<jats:sup>3<\/jats:sup>) and during the 2\u00a0years after the new platelet transfusion protocol (low prophylactic transfusion threshold, 25,000\/mm<jats:sup>3<\/jats:sup>). The primary outcome was the proportion of neonates receiving at least one platelet transfusion in both groups. We also compared the proportion of deaths and severe hemorrhage events. A total of 707 neonates with thrombocytopenia were identified. In the high-threshold group, 99\/360 (27.5%) received at least one platelet transfusion as compared with 56\/347 (16.1%) in the low-threshold group (<jats:italic>p<\/jats:italic>\u2009&lt;\u20090.001).
