This article is from PLoS ONE, volume 9.AbstractBackground: While some prediction models have been developed for diabetic populations, prediction rules for mortality in diabetic dialysis patients are still lacking. Therefore, the objective of this study was to identify predictors for 1-year mortality in diabetic dialysis patients and use these results to develop a prediction model. Methods: Data were used from the Netherlands Cooperative Study on the Adequacy of Dialysis NECOSAD, a multicenter, prospective cohort study in which incident patients with end stage renal disease ESRD were monitored until transplantation or death. For the present analysis, patients with DM at baseline were included. A prediction algorithm for 1-year all-cause mortality was developed through multivariate logistic regression. Candidate predictors were selected based on literature and clinical expertise. The final model was constructed through backward selection. The models predictive performance, measured by calibration and discrimination, was assessed and internally validated through bootstrapping. Results: A total of 394 patients were available for statistical analysis; 82 21% patients died within one year after baseline 3 months after starting dialysis therapy. The final prediction model contained seven predictors; age, smoking, history of macrovascular complications, duration of diabetes mellitus, Karnofsky scale, serum albumin and hemoglobin level. Predictive performance was good, as shown by the c-statistic of 0.810. Internal validation showed a slightly lower, but still adequate performance. Sensitivity analyses showed stability of results. Conclusions: A prediction model containing seven predictors has been identified in order to predict 1-year mortality for diabetic incident dialysis patients. Predictive performance of the model was good. Before implementing the model in clinical practice, for example for counseling patients regarding their prognosis, external validation is necessary.
