The comorbidity scoring systems for predicting survival in elderly dialysis patients

The worldwide elderly dialysis population has grown significantly and is expected to have more comorbid
conditions and shorter life expectancies than the general elderly population. Predicting outcomes for this
population is important for decision-making. Our study is to examine the comorbidity index for outcome
predictability in elderly dialysis patients. In this population-based cohort study, we enrolled elderly patients
who startedmaintenance dialysis in Taiwan. Further analyses of all-cause mortality and life expectancy in these
groups with different comorbidity index score were performed. As results, a total of 21,043 incident dialysis
patients divided into 4 groups by the comorbidity index score (intervals ≤ 3, 4-6, 7-9, ≥ 10) were analyzed.
During a 10-year follow-up, 11272 (53.55%) patients died. Kaplan-Meier curves showed significant survival
differences between groups (log-rank: P < 0.001). After stratification by age, life expectancy was significantly
longer in groups with lower the comorbidity index scores. In conclusion, the comorbidity index is a strong
predictor of mortality in elderly dialysis patients.
