Summary
Optimizing care for older adults on peritoneal dialysis (PD) is crucial. Despite challenges in PD selection and self-care, older patients can achieve good outcomes with tailored renal programs.
Area of Science:
- Nephrology
- Geriatric Medicine
Background:
- Peritoneal dialysis (PD) selection in older adults is a complex process.
- Older individuals face unique challenges in PD assessment and initiation, often defaulting to hemodialysis (HD).
Purpose of the Study:
- To highlight the complexities and barriers in PD selection for older individuals.
- To emphasize the need for optimized care pathways to increase PD utilization in this demographic.
Main Methods:
- Review of factors influencing PD selection in elderly patients.
- Analysis of barriers to PD assessment, eligibility, and self-care.
Main Results:
- Older adults encounter medical instability, palliative care considerations, and reluctance to initiate PD.
- Contraindications, self-care barriers, and patient reluctance further limit PD use.
- Catheter complications and urgent HD can also impede PD receipt.
Conclusions:
- Despite challenges, older patients can achieve positive outcomes with PD.
- Optimizing each step in renal programs is essential to maximize PD use in older patients.

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...

01:18Pharmacokinetics in Geriatric Patients: Effect of Age on Drug Excretion
316
In geriatric patients, renal physiology undergoes significant changes, including diminished renal blood flow and a lower glomerular filtration rate (GFR), leading to alterations in medication clearance. Drugs such as aminoglycoside antibiotics, lithium, and digoxin, which rely on glomerular filtration for removal from the body, particularly impact pharmacokinetics. These drugs tend to have slower clearance rates in older adults, necessitating careful dosage considerations.Evaluation of renal...

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...
