Insights

The Patient Reported Instrument for Engagement in Self-Management for people with Chronic Kidney Disease, receiving Haemodialysis (PRIESM CKD-HD) is a new, valid, and reliable tool. It measures patient engagement in self-management, offering a patient-centered perspective for better support.

Area of Science:

  • Nephrology
  • Psychology
  • Health Services Research

Background:

  • Self-management requires clearer definition in kidney research and practice.
  • Current measures focus heavily on dialysis tasks and adherence.
  • The Patient Reported Instrument for Engagement in Self-Management for people with Chronic Kidney Disease, receiving Haemodialysis (PRIESM CKD-HD) addresses this gap.

Purpose of the Study:

  • To develop and validate a patient-reported measure of self-management engagement for individuals undergoing haemodialysis (HD).
  • To incorporate a biopsychosocial model, capturing daily management, impact, communication, and clinical care aspects.
  • To provide a tool for identifying support needs and fostering discussion on targeted interventions.

Main Methods:

  • Sequential mixed-methods approach including literature review, qualitative interviews (n=27), expert consensus (n=19), and cognitive testing (n=11).
  • Large-scale survey (n=363) across three kidney centers for validation, with subgroup follow-up (n=95).
  • Exploratory factor analysis and correlation analyses with depression and self-efficacy measures.

Main Results:

  • PRIESM CKD-HD demonstrated good validity and reliability, with an overall Cronbach's alpha of 0.92.
  • Exploratory factor analysis supported a three-factor model: daily managing and impact (α=0.91), communication (α=0.84), and clinical care (α=0.66).
  • Strong correlations with depression (r=-0.74) and self-efficacy (r=0.75) supported construct validity. Test-retest reliability was high (r=0.84).

Conclusions:

  • PRIESM CKD-HD is the first measure to capture self-management from the patient's perspective, including psychosocial elements for haemodialysis patients.
  • The findings challenge the notion that some individuals do not wish to self-manage.
  • This instrument can guide tailored support strategies for chronic kidney disease patients on haemodialysis.

Hemodialysis III: Nursing Management

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 measurement...

Chronic Kidney Disease III: Interprofessional Care

Chronic kidney disease (CKD) requires collaborative and comprehensive management. CKD progresses through stages and can lead to end-stage kidney disease (ESKD) if untreated. Interprofessional collaboration and patient education are crucial, enabling patients to manage their health and improve their quality of life.Diagnostic approach for chronic kidney diseaseThe diagnosis of CKD primarily focuses on the glomerular filtration rate (GFR), which assesses kidney function by measuring how well...

Hemodialysis I: Introduction

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...

Chronic Kidney Disease IV: Nursing Management

Nursing management is essential for preventing complications, maintaining stability, and improving patients' quality of life in chronic kidney disease (CKD). By using a structured approach, nurses help slow CKD progression and support effective patient care​.1. Comprehensive patient assessmentEffective management begins with nurses reviewing the patient’s medical history, and identifying key risk factors like diabetes, hypertension, and nephrotoxic drug use. Nurses assess signs of fluid...

Peritoneal Dialysis III: Nursing Management

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...

Hemodialysis II: Procedure and Complications

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,...
