Chronic peritoneal dialysis in the elderly: a review.

During the past few decades, the pattern of end-stage renal disease has changed significantly with the emerging predominance of elderly patients. Because this heterogeneous population is characterized by a physiological decline in function of all organs, the nephrologist must contemplate the special needs of individual patients when they develop end-stage renal disease. Before the initiation of dialysis, these patients must be given detailed information to help them select the particular mode that will maximize their quality of life. According to available data, peritoneal dialysis offers some advantages for elderly patients, such as hemodynamic stability, steady-state metabolic control, good control of hypertension, independence from hospital, and avoidance of repeated vascular access. Early referral promotes the establishment of peritoneal access and minimizes the consequences of uremia, subsequent morbidity, and frequent hospitalization. Elderly patients are compliant and highly motivated to cooperate with their treatment. They have no higher modality-related complications than younger patients and their quality of life is satisfactory. Although most have comorbid conditions that interfere with self-performance of dialysis, such as impaired vision and reduced physical and mental activity, they can perform peritoneal dialysis successfully if they have a high level of family support. Patients who do not have family support may have successful peritoneal dialysis if they have access to a network of medical and social support, that is, private home nurses, rehabilitation and chronic care dialysis units, or nursing homes.
