Paediatric index of mortality (PIM): a mortality prediction model for children in intensive care

Abstract

Scores that use the worst value of their predictor variables in the first 12-24 h should not be used to compare different units: patients mismanaged in a bad unit will have higher scores than similar patients managed in a good unit, and the bad unit's high mortality rate will be incorrectly attributed to its having sicker patients. PIM is a simple model that is based on only eight explanatory variables collected at the time of admission to intensive care. It is accurate enough to be used to describe the risk of mortality in groups of children.

Incidence and short-term outcome of acute lung injury in mechanically ventilated children

“…Two possible explanations for the findings were considered. Firstly, the PIM may not be reliable for specific diagnostic subgroups such as ALI, because it was developed for a PICU population as a whole [11]. This explanation is supported by a recent report, where the PIM of children with respiratory failure showed a smaller AUC than the overall PICU population [36].…”

“…For the estimation of severity of disease and for comparison between survivors and nonsurvivors the paediatric index of mortality (PIM) [11], the paediatric risk of mortality score (PRISM) II [12] and a maximum score for multiorgan system failure (MOSF) during hospitalisation were assessed [13]. In addition to the well-developed indices for mortality prediction at admission (i.e.…”

Risk factors for healthcare-associated infection in pediatric intensive care units: a systematic review

“…Intrinsic factors generally include age, gender, nutritional status, underlying disease and severity of the illness. To assess disease severity and to predict the risk of death, scores such as the Paediatric Risk of Mortality (PRISM), or its modified PRISM III version, and the Paediatric Index of Mortality (PIM) or its PIM II modification have been used 9,10,11,12,13,14,15 . Extrinsic factors such as aspects of treatment, available structure and the quality of care have been studied as well 16 .…”

The effect of neuromuscular blockade on oxygen consumption in sedated and mechanically ventilated pediatric patients after cardiac surgery

“…This device has been validated in small children [12,13]. We also collected PIM and PRISMII scores reflecting severity of illness [14,15]. Furthermore, we collected data concerning length of stay (LOS), diagnosis, weight, height, and age.…”
