Overall and subgroup specific performance of the pediatric index of mortality 2 score in Switzerland: a national multicenter study

Conclusion: The performance of the PIM 2 score in a cohort of Swiss patients is poor with adequate discrimination and poor calibration. The PIM 2 score tends to under predict the number of deaths among septic patients and in patients admitted after a cardiorespiratory arrest.What is Known:•PIM2 score is a widely used mortality prediction model in PICU.•PIM2 performance among uncommon but clinically relevant diagnostic subgroups of patients is unknown.•The performance of PIM2 score has never been assessed in Switzerland.What is New:•The performance of the PIM 2 score in a cohort of Swiss patients is poor with adequate discrimination and poor calibration.•Calibration varies significantly according to primary diagnosis. The PIM 2 score under predict the number of deaths among septic patients and in patients admitted after a cardiorespiratory arrest.
