Peritoneal dialysis: update on patient survival
Clinical Nephrology
|October 28, 2014
Summary
Patients with end-stage renal disease (ESRD) requiring dialysis have similar survival rates with hemodialysis (HD) versus peritoneal dialysis (PD). Lifestyle and quality of life should guide the choice between HD and PD modalities.
Area of Science:
- Nephrology
- Renal Replacement Therapy
- Clinical Outcomes Research
Background:
- End-stage renal disease (ESRD) necessitates dialysis for most patients due to kidney transplant limitations.
- Hemodialysis (HD) and peritoneal dialysis (PD), including continuous ambulatory PD (CAPD) and automated PD (APD), are the primary dialysis modalities worldwide.
- Observational data on dialysis survival are complex due to confounding factors and difficulties in patient randomization.
Purpose of the Study:
- To review and analyze long-term survival data comparing hemodialysis (HD) with peritoneal dialysis (PD).
- To compare survival outcomes between continuous ambulatory PD (CAPD) and automated PD (APD).
- To assess the evolution of survival equivalence across different dialysis modalities over time.
Main Methods:
- Systematic review of observational studies on dialysis patient survival over several decades.
- Analysis of survival data comparing HD versus PD.
- Comparative analysis of CAPD versus APD survival outcomes.
Main Results:
- Recent data (last 10-15 years) indicate virtual equivalence in overall survival between HD and PD.
- Survival outcomes for CAPD and APD show a similar pattern of equivalence.
- Improved statistical methods for observational data have clarified survival trends.
Conclusions:
- Survival rates are comparable between hemodialysis and peritoneal dialysis, including CAPD and APD.
- The choice of dialysis modality should prioritize patient lifestyle and quality of life.
- Nephrologists and patients can focus on non-survival factors when selecting dialysis treatment.

Peritoneal dialysis (PD) is a procedure that facilitates the exchange of solutes, waste products, electrolytes, and excess fluid between the blood in the peritoneal capillaries and a dialysis solution introduced into the peritoneal cavity.Principles of Peritoneal Dialysis (PD)Diffusion: Waste products such as urea and electrolytes move from high concentrations in the blood to low concentrations in the dialysate across the peritoneal membrane. This mechanism is driven by the concentration...

Peritoneal dialysis, or PD, utilizes the peritoneal membrane as a filter to eliminate excess fluid and waste products. Effective nursing management is essential for ensuring patient safety, preventing complications, and promoting optimal function of the peritoneal dialysis process.Assessment and MonitoringNurses must thoroughly assess the patient before, during, and after each dialysis session. Regular monitoring includes vital signs, daily weight, fluid intake and output, and laboratory values...

Renal failure occurs when the kidneys lose their ability to filter waste products from the blood effectively. It can be classified into two types: acute renal failure (ARF) and chronic renal failure (CRF).
Acute kidney injury develops suddenly and can be caused by pre-renal causes (e.g., hypovolemia, shock), intrinsic renal causes (e.g., acute tubular necrosis), or post-renal causes (e.g., urinary obstruction). In contrast, chronic renal failure progresses gradually over time and is often...

Dialysis is a diffusion-based purification process that separates analyte molecules from a complex matrix. This is accomplished by allowing molecules in the solution to pass through a semipermeable membrane into a liquid on the other side. The membrane is usually made of cellulose acetate or cellulose nitrate, and the second liquid must be miscible with the solution. Ions (e.g., chloride or sodium) or organic molecules (e.g., glucose) can pass through the membrane pores, which generally have...

1.1K
Patients with end-stage renal disease (ESRD) or those experiencing drug overdose often require extracorporeal methods to eliminate accumulated drugs and metabolites. Hemoperfusion, hemofiltration, and dialysis are the primary techniques to rapidly remove harmful substances without disrupting the patient's fluid and electrolyte balance. For those with compromised renal function, dosage adjustments of concurrent medications may be necessary during extracorporeal drug removal.Dialysis is a process...
