The worldwide elderly (≥65 years old) 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. There are some studies about comorbidity scoring systems for predicting survival in dialysis patients. To establish a simple and practicable scoring system for predicting survival in the elderly population is increasingly important for physicians worldwide. The aim of this critical review was to discuss the comorbidity scoring systems for predicting survival in elderly dialysis patients and additional management strategies.
Of the current comorbidity scoring systems for predicting survival in dialysis patients, the Charlson comorbidity index is considered the most predictive one than any other commonly used comorbidity scoring systems. Recently, a new comorbidity index with good predictive value for patient outcomes was developed and validated in chronic dialysis patients. The new comorbidity index, even without the age component, is a strong predictor of mortality in elderly dialysis patients. Using one or both of these scoring systems, a physician may be able to provide some helpful objective opinions and suggestions to elderly patients who must choose between initiating and not initiating dialysis.
