Logistic regression was used to estimate the probability of having at least 1 complication not present on admission. The complications model had a C statistic of 0.64, and the Hosmer-Lemeshow goodness of fit test using 7 groups was not significant (P = .30). The link function used was the logit function. The error distribution is assumed to be Bernoulli. Three variables were log-transformed: number of diagnoses, total costs, and length of stay.
