Survival on dialysis therapy: one center's experience

Area of Science:

• Nephrology
• Internal Medicine
• Clinical Epidemiology

Background:

• Renal replacement therapy is crucial for end-stage renal disease patients.
• Evaluating survival across different dialysis modalities is essential for patient care.
• Long-term outcomes for continuous ambulatory peritoneal dialysis (CAPD) require careful comparison with other methods.

Purpose of the Study:

• To evaluate patient survival on renal replacement therapy.
• To compare survival rates among continuous ambulatory peritoneal dialysis (CAPD), home hemodialysis (HHD), and free-standing dialysis facility (LCD) treatments.
• To identify factors influencing patient survival during dialysis.

Main Methods:

• Retrospective analysis of 1,216 patients undergoing renal replacement therapy from 1967 to 1986.
• Categorization of patients into CAPD, HHD, and LCD groups.
• Covariate analysis to assess the impact of demographic factors and renal failure etiology on survival.

Main Results:

• Patient survival was not influenced by race, sex, or marital status.
• Survival was poorest in patients over 60 years old and those with diabetes or hypertension as the cause of renal failure.
• CAPD was associated with diminished survival compared to HHD, but not LCD, in unadjusted analyses.

Conclusions:

• Age and specific comorbidities (diabetes, hypertension) significantly impact survival on dialysis.
• While CAPD showed lower survival than HHD in this cohort, matched analyses suggest initial technique may not be the sole determinant.
• Further randomized prospective trials are needed to definitively compare the long-term efficacy of CAPD versus HHD for patient maintenance at home.
