title: [Factors predicting survival in patients on peritoneal dialysis].
abstract: OBJECTIVE
  To determine the factors associated with survival in a cohort of 74 patients with end-stage renal disease (ESRD) undergoing chronic peritoneal dialysis (CPD).
  
  
  METHODS
  The study was carried out at a general hospital of the Instituto Mexicano del Seguro Social.
  
  
  METHODS
  Analysis of a retrolective cohort under a nested case control design.
  
  
  METHODS
  The variables studied included age, gender, cause of ESRD (diabetic or non-diabetic), socioeconomic status, modality of CPD (intermittent vs continuous ambulatory peritoneal dialysis), catheters per patient, rate of peritonitis, levels of serum creatinine and albumin at the beginning of the CPD.
  
  
  RESULTS
  During a 75.1 years-patient follow up, there were 41 deaths (cases). The main cause of death was peritonitis. The cumulated survival of the 74 patients was 64%, 29% and 13% at 12, 24 and 33 months, respectively. Intermittent peritoneal dialysis, the rate of peritonitis and the level of basal serum albumin were associated with a decreased survival in a univariate analysis. Only a high rate of peritonitis was associated with an increase in mortality rate independent from other variables (p = 0.002).
  
  
  CONCLUSIONS
  The probability of survival in ESRD in our hospital was low in relation to other nephrology departments of Mexico and other countries. A high rate of peritonitis proved to be an important independent predictor of a lesser survival rate in patients under CPD in our institution.
