Peritoneal dialysis in nondiabetic patients older than 70 years : Comparison with patients aged 40 to 60 years

Abstract In all industrial countries, the number of elderly patients who need dialysis has increased in recent years. In the present study, we retrospectively analyzed two different age groups of nondiabetic peritoneal dialysis patients treated at the same unit by the same team of physicians and nurses with the same protocols. However, our purpose was to study possible differences in technique and survival rates, causes of dropout, complications, hospitalization rate, and everyday needs between the two groups. The results of 63 consecutive nondiabetic patients older than 70 years treated with continuous ambulatory peritoneal dialysis (CAPD) were compared with those of 86 nondiabetic patients aged 40 to 60 years treated during the same period. Patient survival was significantly worse in the elderly patients, but the observed to expected survival ratio with respect to age was similar. Technique survival was comparable in the two groups. Total hospitalization was 5,501 days (32 d/yr) in the elderly patients and 4,511 days (18 d/yr; P
