Development of a Pediatric Risk Assessment Score to Predict Perioperative Mortality in Children Undergoing Noncardiac Surgery.

BACKGROUND: Although there have been numerous attempts to predict perioperative mortality in adults, an objective model to predict mortality in children has not been developed. In this study, we aimed to develop a Pediatric Risk Assessment (PRAm) score to predict perioperative mortality in children undergoing noncardiac surgery. METHODS: We included all children recorded in the 2012 and 2013 American College of Surgeons National Surgical Quality Improvement Program Pediatric databases in a derivation cohort and those from the 2014 database in a validation cohort. The primary outcome was the incidence of in-hospital mortality. A total of 115,229 (63%) were included in the derivation cohort and 68,194 (37%) in the validation cohort. We used multivariable logistic regression to determine the predictors for mortality and designed the PRAm score. RESULTS: On the basis of the multivariable regression model, we created a simplified risk assessment tool (PRAm score) ranging from 0 to >=9, including the presence of any comorbidities, factors of critical illness, age =4, there is wide variability in objectively obtained PRAm scores.
