Dialysis

1.7K
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

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...

Hemodialysis III: Nursing Management

1.2K
The nursing management of a patient undergoing hemodialysis includes several critical steps, starting with a thorough assessment before the procedure.Before the Hemodialysis ProcedureFirst, record the patient's vital signs—blood pressure, heart rate, respiratory rate, and temperature—to establish a baseline. This baseline is essential for detecting conditions such as hypotension that could impact the patient's response to dialysis. Document the patient's pre-dialysis weight, as this...

Hemodialysis I: Introduction

2.3K
Hemodialysis (HD) is a medical treatment that artificially removes waste products, excess fluids, and toxins from the blood when the kidneys are no longer able to perform these functions effectively. In this process, blood is filtered through a semipermeable membrane, allowing for the selective removal of waste while preserving necessary components like blood cells and proteins. Hemodialysis is typically performed in patients with end-stage renal disease (ESRD) or severe kidney...

Postoperative Nursing Management for Kidney Transplant PatientsPostoperative nursing management care includes monitoring the surgical site, encouraging early movement, and promoting lung health through breathing exercises. Nurses also administer prescribed medications like H2-blockers, such as famotidine, or proton pump inhibitors, like omeprazole, to help prevent gastrointestinal ulcers and bleeding. Fungal infections in the mouth and bladder can result from immunosuppressive and antibiotic...

DialyzersA hemodialysis (HD) dialyzer is a plastic cartridge containing thousands of parallel hollow fibers, which serve as semipermeable membranes. These fibers are typically made from cellulose-based or other synthetic materials. During HD, blood is pumped into the top of the cartridge and distributed among these fibers. Simultaneously, dialysis fluid, known as dialysate, is introduced into the bottom of the cartridge, bathing the outside of the fibers. Across the semipermeable membrane,...

Area of Science:

  • Nephrology
  • Health Informatics
  • Patient Adherence Research

Background:

  • Comorbidities and socioeconomic factors present significant barriers to hemodialysis adherence and self-management.
  • Missed hemodialysis sessions, often due to communication issues, lead to emergency treatments and preventable hospitalizations.

Purpose of the Study:

  • To evaluate the efficacy of a novel digital-messaging platform, EpxDialysis, in enhancing patient-to-dialysis center communication.
  • To assess the impact of EpxDialysis on appointment adherence and hospitalization rates among hemodialysis patients with poor attendance.

Main Methods:

  • A randomized controlled trial with a cross-over design was conducted at Washington University-affiliated hemodialysis centers.
  • The study involved End-Stage Renal Disease (ESRD) patients exhibiting poor attendance (2-6 missed sessions in 12 weeks).
  • Appointment adherence and hospitalization data were compared pre- and post-intervention using the EpxDialysis platform (text messaging and telephone).

Main Results:

  • Median appointment adherence increased by 75% after implementing EpxDialysis.
  • Median unintended hospitalization days decreased by 31% among participating patients.
  • A cost-benefit analysis indicated a 1:36 savings ratio attributed to improved appointment adherence.

Conclusions:

  • EpxDialysis is a low-risk, cost-effective intervention for improving hemodialysis adherence in high-risk patient populations.
  • The digital platform shows particular promise for centers serving vulnerable and low-income patient groups.
  • Enhanced communication through EpxDialysis can mitigate missed sessions and reduce associated healthcare costs.
