Abstract

BACKGROUND:

Chronic kidney disease (CKD) is becoming increasingly prevalent and there are increasing numbers of older patients with advanced CKD. Peritoneal dialysis (PD) is a potential treatment. This study aims to compare PD outcomes in age-defined populations in the largest PD centre in the Republic of Ireland over 10 years.

METHODS:

We retrospectively identified all adult patients, over the age of 50 years, who commenced PD as their first modality of renal replacement therapy (RRT) between 1 January 1998 and 31 December 2008 at our institution. Primary outcome was patient survival; secondary outcomes were technique failure, peritonitis-free survival, transplantation and hospitalisations.

RESULTS:

One hundred and forty-eight patients with a mean age of 63 years were included. Twenty-two patients were on assisted PD, the majority of whom were aged 70 years or over (P = 0.001). There were no differences in patient survival or technique failure by age group, Charlson Co-Morbidity Index (CCI), modified-CCI or adjusted CCI. Renal transplantation occurred predominantly in younger patients (P = 0.001) with lower m-CCI (P = 0.001) and a-CCI (P = 0.002) who performed PD independently (P = 0.004). Older patients required longer hospital stays to initiate PD (P = 0.004). Assisted PD was not associated with an increase in early complications or technique failure but death rates were higher (P = 0.002).

CONCLUSION:

This study shows PD to be an acceptable modality of renal replacement therapy in elderly patients, with no observed differences in survival, technique survival or complication rates. Co-morbidities appear to play a stronger role in predicting survival than age alone. Assisted PD is a viable option in those unable to undergo PD independently.
