Davies et al identified factors predictive of survival of a patient undergoing continuous peritoneal dialysis (CAPD). These can help to identify a patient who may benefit from more aggressive management. The authors are from Staffordshire Hospital in Stoke-on-Trent, England.


Patient selection: chronic renal failure with continuous ambulatory peritoneal dialysis


Predictors of worse survival from multivariate analysis:

(1) greater comorbidity

(2) older age


The grade of comorbidity tended to increase with age.


Peripheral vascular disease and left ventricular dysfunction were important comorbid conditions associated with worse survival.


Additional factors (from the univariate analysis):

(1) hypoalbuminemia

(2) poor dietary intake of calories and protein (influenced by appetite)

(3) low dialysis dose (lower Kt/V)
