Insights

A new pediatric haemodialysis trigger tool (pHTT) significantly reduced adverse events in children undergoing dialysis. This bedside tool helps improve patient safety by systematically monitoring and reporting potential harms during haemodialysis sessions.

Area of Science:

  • Pediatric Nephrology
  • Patient Safety
  • Quality Improvement in Healthcare

Background:

  • Intermittent in-centre haemodialysis (HD) in children requires systematic monitoring for adverse events.
  • Existing patient safety systems may not adequately capture all potential harms during pediatric HD sessions.
  • A validated tool is needed to identify and address adverse events in pediatric haemodialysis.

Purpose of the Study:

  • To develop and evaluate a pediatric haemodialysis trigger tool (pHTT) for use during intermittent in-centre HD sessions in children.
  • To systematically monitor adverse events and assess the impact of interventions informed by the pHTT on patient safety.
  • To determine the feasibility and effectiveness of a bedside tool in reducing harm rates during pediatric haemodialysis.

Main Methods:

  • A single-centre quality improvement study was conducted over two 8-week cycles.
  • A pediatric haemodialysis trigger tool (pHTT) with 54 triggers across six domains was developed and prospectively applied.
  • Haemodialysis nurses completed the pHTT at the end of each dialysis session, with triggers evaluated for harm level.

Main Results:

  • A total of 241 triggers were identified over 182 dialysis sessions involving 28 children.
  • Following interventions based on pHTT data, the harm rate per session significantly decreased from 1.03 to 0.32 (P < 0.001).
  • Significant differences were observed in trigger distribution by harm category and pHTT domains between the two study cycles; no permanent harm was reported.

Conclusions:

  • The pilot study demonstrates the potential benefits of a bedside pHTT for monitoring adverse events in pediatric haemodialysis.
  • Interventions informed by the pHTT led to a significant reduction in the harm rate per session.
  • The study proposes the routine use of a pediatric haemodialysis trigger tool in centers providing HD to children to enhance patient safety.

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...

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,...

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...

Acute Kidney Injury IV: Diagnostic Studies and Prevention

Accurate diagnosis and effective prevention are critical in managing Acute Kidney Injury (AKI), which is linked to high mortality rates ranging from 10% to 80%. Timely recognition of at-risk patients and careful monitoring can significantly reduce the likelihood of kidney damage.Diagnostic Assessments:The diagnostic process starts with a comprehensive medical history to identify prerenal, intrarenal, and postrenal causes.Prerenal causes, such as dehydration, hypotension, or blood loss, should...

Acute Kidney Injury V: Interprofessional Care

Acute Kidney Injury (AKI) requires a collaborative healthcare approach to restore renal function and prevent complications. Essential management strategies involve monitoring fluid and electrolyte balance, adjusting medications, initiating dialysis when necessary, and providing nutritional support.Fluid and Electrolyte ManagementFluid Monitoring: Regularly monitoring body weight, central venous pressure, and urine output helps detect fluid imbalances early.

Dialysis

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...
