Quality of life in the elderly patients on dialysis

Abstract

The pattern of end-stage renal disease (ESRD) has changed significantly with the emerging predominance of elderly patients. Age is no longer seen as a contraindication to dialysis. Based on 2004 data, in the USA, patients aged 45-64 years old comprise the largest portion of the incident population, while patients aged 75 and older have the highest incident rates of ESRD. Mortality is higher among the elderly dialysis patients for whom cardiovascular diseases and infections are the most common causes of death. The quality of life (QoL) of these patients has been found to vary in different investigations, dependent on such factors as the investigator(s), the composition of the study group and the criteria used, among others; however, age was always found one of the major determinants of their QoL. Quality-of-life data suggest that older dialysis patients have similar levels of social functioning and mental health as younger dialysis patients but that their level of physical functioning is poorer. As such, the survival and QoL of elderly patients depends mainly on the severity of the comorbid conditions. The rationing of dialysis on the basis of age alone is not justified as dialysis can provide elderly patients with the means to gain the health status that permits them to enjoy life, but in their own way.
