Abstract

Objective: We developed a new nomogram for the prediction of mortality risk in children in pediatric intensive care units (PICU).

Methods: We conducted a retrospective analysis using the PICU Public Database, a study that included a total of 10,538 children, to develop a new risk model for mortality in children in the intensive care units (ICU). The prediction model was analyzed using multivariate logistic regression with predictors including age and physiological indicators, and the prediction model was presented as a nomogram. The performance of the nomogram was evaluated based on its discriminative power and was internally validated.

Results: Predictors contained in the individualized prediction nomogram included the neutrophils, platelets, albumin, lactate, oxygen saturation (P<0.1). The area under the receiver operating characteristic (ROC) curve for this prediction model is 0.7638 (95% CI: 0.7415-0.7861), which has effective discriminatory power. The area under the ROC curve of the prediction model in the validation dataset is 0.7404 (95% CI: 0.7016-0.7793), which is still effectively discriminative.

Conclusion: The mortality risk prediction model constructed in this study can be easily used for individualized prediction of mortality risk in children in pediatric intensive care units.

Nomogram for predicting mortality of pediatric ICU. To use the nomogram, an individual patient’s value is located on each variable axis, and a line is drawn upward to determine the number of points received for each variable value. The sum of these numbers is located on the Total Points axis, and a line is drawn downward to the risk axes to determine the risk of mortality.
