[Patient survival, a change in methods, and hospitalization in CAPD abd hemodialysis]
Unlabelled:
BACKGROUND AND OBJECTIVE OF STUDY: Continuous ambulatory peritoneal dialysis (CAPD) still plays a minor role in Germany compared with haemodialysis (HD) in the management of terminal renal failure. An investigation was undertaken to compare mortality rate, change of dialysing method as well as number and duration of hospital stays of patient undergoing CAPD or HD at a nephrological centre.
Patients And Methods:
All 166 patients in terminal renal failure (except those with a malignancy) admitted between January 1987 and December 1992 were included (63 women and 103 men, aged 19-84 years). The choice between the two dialysis methods was made by the patients after detailed information had been given. Taking into account basic disease and any secondary illness as well as age and sex, survival time, any change of dialysing method and hospitalisation details were prospectively analysed for the two dialysing methods.
Results:
After 4 years there were no significant differences in mortality rate between the two methods (HD 37%, CAPD 29%). The Cox model revealed no influence of various parameters on the mortality rate of the two methods. However, cumulative patients survival was significantly decreased by arterio-sclerotic disease (P < 0.05; probability of survival after 4 years was 53% and 73%, respectively, for HD and 57% and 77% for CAPD). Similarly, age > or = 60 years at onset of dialysis significantly lowered probability of survival (after 4 years of dialysis, 53% vs 70% for HD, 45% vs 80% for CAPD: P < 0.05). But there were no significant differences between the two methods with respect to these two factors. After 4 years, "method survival" was more common with HD (94%) than CAPD (64%), P < 0.05). In particular diabetics had a significantly lower "method survival" after 4 years than non-diabetics (29% vs 74%). There was no significant difference between the two methods regarding number and duration of hospital stays.
Conclusions:
These data show that, in a nephrological centre with long experience in both methods of dialysis, CAPD is an equal alternative to HD.
