Abstract
A validated age and comorbidity prognostic index for survival in dialysis patients
Highlights
In 2007, we described a prognostic index (ACPI) for survival in the dialysis population based on 11 comorbid conditions and age [1]
The cohort consisted of 339 patients with endstage renal disease (ESRD) who began chronic haemodialysis between January 2003 and December 2008
This index was designed on patients admitted in a medical institution with different diagnoses and validated in a cohort of breast cancer patients, populations which are not comparable with those patients with ESRD
Summary
In 2007, we described a prognostic index (ACPI) for survival in the dialysis population based on 11 comorbid conditions and age [1]. To demonstrate that a predictive model is valuable, evidence that it performs successfully for other groups of patients is needed; this process is called validation [2,3,4,5,6]. We tested the ability of our index to predict the risk of death from comorbid conditions and age, in a cohort comprised of the incident patients acquired by our dialysis centers in the five years following the first study. We here report a validation study, that prospectively evaluated data from a cohort independent of the former test group. We performed this study to assess the reproducibility of the ACPI
