SOUSA-AMORIM, Erika De et al. Thirty years in a peritoneal dialysis unit: long-term survival. Nefrología (Madr.) [online]. 2013, vol.33, n.4, pp.546-551. ISSN 1989-2284.  https://dx.doi.org/10.3265/Nefrologia.pre2013.Apr.11956.

Background and objective: Peritoneal dialysis (PD) is an establish renal replacement therapy that has evolved in the last decades thanks to technological and clinical advances showing improving survival rates. The aim of this study was to evaluate the patient and technique survival in PD over 30 years of experience and in the different decades. Patients and method: Retrospective cohort study including all patients in the PD unit of the Hospital Universitario La Paz (Madrid), from 1980 to 2010. Demographics and clinical variables were collected from medical records. Results: A total of 667 patients were included, 54.4% males, with a mean age of 51.47 years and a median follow-up of 23.1 months. There was an increased in PD incident patients, especially in automatic PD (APD). Patient survival at 5 years was 54%, with a median of 64.66 months, increasing significantly in the last decade (p=0.000). Age, comorbidity, male sex, chronic ambulatory PD and diabetes were independently predictor of patient survival. Technique survival at 5 years was 64.2% and median 82 months. Younger patients, in APD and with less comorbity showed better technique survival. Conclusions: Over 30 years of experience we found an increased in incident patients. Age, comorbidity and diabetes were still the main predictors of survival.
