Why the study?
Does the Pediatric Index of Mortality 2 (PIM-2) accurately predict mortality in pediatric cardiac surgery patients?
Does the Pediatric Index of Mortality 2 (PIM-2) accurately predict mortality in pediatric cardiac surgery patients?
The PIM-2 score demonstrates poor calibration and predictive ability for pediatric cardiac surgery patients and is not recommended as an adequate adjustment tool for quality measurement in this population.
