Dialysis

465
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...

Hemodialysis III: Nursing Management

172
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...

Chronic Kidney Disease I: Introduction

65
Chronic Kidney Disease (CKD) arises when the kidneys progressively lose their ability to function, ultimately leading to end-stage renal disease. At this advanced stage, the kidneys can no longer filter waste or maintain essential body functions, requiring renal replacement therapy (RRT) through dialysis or a kidney transplant for survival.Early-stage chronic kidney disease and detection challengesIn CKD's early stages, symptoms often remain absent because healthy nephrons compensate for...

Hemodialysis I: Introduction

279
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

126
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,...

Kidney Transplant I: Introduction01:28

Kidney Transplant I: Introduction

59
A kidney transplant is a surgical approach that involves replacing a non-functioning kidney with a healthy one from a donor. This procedure is often a treatment option for end-stage renal disease (ESRD) patients. The method requires careful recipient selection, including evaluating various medical and psychosocial factors. These criteria vary between transplant centers but generally include assessments of the patient's overall health, adherence to medical recommendations, and lifestyle...

Summary

Suboptimal dialysis initiation is frequent in advanced chronic kidney disease (CKD) patients. Higher hemoglobin levels reduced risk, while comorbidity and more nephrologist visits increased risk, but no modifiable patient factors were found.

Area of Science:

  • Nephrology
  • Public Health

Background:

  • Suboptimal dialysis initiation is a prevalent issue in advanced chronic kidney disease (CKD).
  • It is linked to increased patient morbidity and mortality.
  • Identifying risk factors is crucial for improving patient outcomes.

Purpose of the Study:

  • To identify risk factors for suboptimal dialysis initiation in patients with advanced CKD.
  • To analyze associations between patient characteristics and suboptimal dialysis start.

Main Methods:

  • Prospective cohort study of English-speaking patients without cognitive impairment in multidisciplinary kidney clinics.
  • Follow-up included a 6-month visit and healthcare administrative data.
  • Suboptimal dialysis initiation defined as initiation during hospitalization or with a central venous catheter in patients <75 years old.
  • Adjusted cause-specific hazard models were used.

Main Results:

  • 33% of 366 patients experienced suboptimal dialysis initiation.
  • Higher time-varying hemoglobin was associated with lower risk (aHR 0.96).
  • Higher comorbidity index and more nephrologist visits (within 6 months) were associated with higher risk (aHR 1.17 and 1.70, respectively).
  • Health literacy, kidney disease knowledge, and influenza vaccination were not associated with suboptimal initiation.

Conclusions:

  • Suboptimal dialysis initiation remains common even with established nephrology care.
  • No readily modifiable patient-related risk factors were identified in this study.
  • Further research may be needed to explore other contributing factors.
