PICU- FE: A longitudinal analysis-ready dataset of harmonized hourly vital signs time-series from a Spanish Paediatric Intensive Care Unit

Description PICU-LaFe is a longitudinal, analysis-ready dataset comprising 14 years (2011–2024) of high-resolution clinical data from the Paediatric Intensive Care Unit (PICU) at the Hospital Universitari i Politècnic La Fe (Valencia, Spain). This dataset provides a curated resource for the development and validation of machine learning models in paediatric critical care, featuring harmonized vital signs time-series for 11,891 unique patients (aged 0–16 years). The data is presented in a single-table, long-format CSV structure to minimize data engineering overhead. Key Features: Temporal Scope: May 19, 2011, to January 9, 2024. Scale: 1,155,211 hourly-resolution records (12,910 unique episodes). Parameters: Heart Rate (HR), Respiratory Rate (RR), Oxygen Saturation (SpO2), Temperature, and Blood Pressure (Systolic, Diastolic, Mean), including the monitoring source (invasive vs. non-invasive). Outcome: Mortality status (Alive/Exitus) for each admission (1.39% mortality rate).
