Abstract
The objective of this study was to define current blood transfusion practices among European pediatric intensive care physicians treating critically ill children. A questionnaire of case scenarios was administered to members of the European Society of Pediatric and Neonatal Intensive Care (ESPNIC). Of the 258 members of the ESPNIC, 134 (51.9%) pediatric intensive care physicians completed the questionnaire. The suggested blood transfusion thresholds for case scenario 1 (post-orthopedic surgery child) ranged from <7.0 g/dl to 11 g/dl. A total of 57.3% suggested 7 g/dl, 33.6% suggested 8 g/dl, and 6.9% suggested 9 g/dl as a hemoglobin threshold for transfusion (mean, 7.54 +/- 0.75). For case scenarios 2 to 4, the suggested hemoglobin thresholds were 7 g/dl to 12 g/dl. For case scenario 2 (a child with acute respiratory distress syndrome), 22.4% suggested 8 g/dl, 15.7% suggested 9 g/dl, and 41% suggested 10 g/dl as a hemoglobin threshold for transfusion (mean, 9.40 +/- 1.27 g/dl). For case scenario 3 (a post-cardiac surgery infant), 20.1% suggested 7 g/dl, 24.6% suggested 8 g/dl, 21.6% suggested 9 g/dl, and 23.9% suggested 10 g/dl as a hemoglobin threshold for transfusion (mean, 8.72 +/- 1.24 g/dl). For case scenario 4 (a child with septic shock), 23.1% suggested 8 g/dl, 16.4% suggested 9 g/dl, and 41% suggested 10 g/dl as a hemoglobin threshold for transfusion (mean, 9.45 +/- 1.24 g/dl). The threshold for transfusion was not statistically different (P >.05) between the physicians according to their subspecialty, years of experience, or country of origin. The suggested volume of transfused blood was 10 to 15 ml/kg in 427 responses (82.6%) and 20 ml/kg in 89 responses (17.2%). Most physicians, 78/128 (60.9%), did not consider the age of the transfused blood an important factor in their decision to transfuse. Of the 106 (79.1%) physicians who detailed their considerations for elevating the threshold for transfusion, 82 (77.3%) gave a general nonspecific indication, 47 (44.3%) stated hemodynamic instability and shock, and 40 (37.7%) an ongoing bleeding. The hemoglobin threshold for blood transfusion and transfusion volume varies among European pediatric intensive care physicians, for the same patient.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
