This model resulted from preliminary analyses of 19 potential predictors, with removal of 9 predictors having p-values >0.10. The generalized linear model used robust estimation of the variance-covariance matrix and was based on the gamma family and log link, which produced the best fit according to AIC and BIC values. In addition to the predictors shown in the table, the model was adjusted for whether the patient was attributed to the lower-cost safety-net hospital.
