Chronic peritoneal dialysis in the tenth decade of life

Abstract

In this retrospective study we present our experience with chronic peritoneal dialysis in nine patients with ESRD in their 10th decade of life (≥90 years) at the Toronto Western Hospital. A family member or a private nurse assisted all patients in dialysis procedure. The co-morbid illnesses, survival, hospitalizations and complications related or unrelated to peritoneal dialysis were reviewed. Four patients started dialysis before and five after their 90th birthday, their mean age was 90.61 ± 4.04 years. All patients had three or more co-morbid illnesses at the start of dialysis. Total duration of PD treatment was 210 patient months with a median duration of 25 months (range 4–68 months). Of the nine patients, four died after a mean follow up of 38.5 months on dialysis. Of the remaining five, one was transferred to hemodialysis after remaining for 10 months on peritoneal dialysis and the other four are continuing on PD for a mean duration of 9.25 months. Peritonitis (1/13.4 patient months) and exit site infection (1/100.5 patient months) responded to treatment. Hospitalization rate was one admission per 2.5 patient years. Most often, the cause of hospitalization was unrelated to PD, e.g., cardiovascular events, pneumonia and peripheral vascular disease etc. Patient survival at 1, 3 and 5 years was 88%, 58% and 24% respectively. The technique survival was 69%, 47% and 23% at 1, 3 and 5 years respectively. We conclude that continuous peritoneal dialysis is a safe and suitable treatment even in nonagenarians (≥90 years) ESRD patients.
