Hemoglobin Levels Across the Pediatric Critical Care Spectrum: A Point Prevalence Study

Objectives: To determine the prevailing hemoglobin levels in PICU patients, and any potential correlates. Design: Post hoc analysis of prospective multicenter observational data. Settings: Fifty-nine PICUs in seven countries. Patients: PICU patients on four specific days in 2012. Interventions: None. Measurements and Main Results: Patients’ hemoglobin and other clinical and institutional data. Two thousand three hundred eighty-nine patients with median age of 1.9 years (interquartile range, 0.3–9.8 yr), weight 11.5 kg (interquartile range, 5.4–29.6 kg), and preceding PICU stay of 4.0 days (interquartile range, 1.0–13.0 d). Their median hemoglobin was 11.0 g/dL (interquartile range, 9.6–12.5 g/dL). The prevalence of transfusion in the 24 hours preceding data collection was 14.2%. Neonates had the highest hemoglobin at 13.1 g/dL (interquartile range, 11.2–15.0 g/dL) compared with other age groups (p
