N2  - Objective 
    To develop a comorbidity model for children that can be used with hospital discharge administrative databases.Design 
    Retrospective study using administrative data obtained from the Canadian Institute for Health Information Discharge Abstract Database and the Deaths File to develop a logistic regression model. Hosmer-Lemeshow χ2 test was used to examine model fit. The C statistic was used to assess model discrimination. Bootstrapping was used to determine the stability of regression coefficients.Setting 
    We used linked administrative databases to compile 339 077 hospital discharge abstracts from April 1, 1991, through March 31, 2002.Participants 
    Children between ages 1 and 14 years in Ontario, Canada.Main Outcome Measure 
    Death within 1 year of hospital discharge.Results 
    The 27-variable pediatric comorbidity model predicted 1-year mortality with a C statistic of 0.83 in the Ontario data set from which it was derived. The presence of brain cancer (odds ratio, 76.38 [95% confidence interval, 53.40-109.27]) at hospital admission was the strongest predictor, followed by diabetes insipidus (odds ratio, 39.23 [95% confidence interval, 20.75-74.17]).Conclusion 
    Using clinical judgment and empirical modeling strategies, we were able to identify 27 diagnoses highly predictive of death for children between 1 and 14 years of age within 1 year of hospital discharge.
