Dialysis

408
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 I: Introduction

90
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

60
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...

Peritoneal Dialysis II: Peritoneal Dialysis Systems and Complications

Peritoneal dialysis (PD) is a medical process that removes waste products and excess fluid from the body using the peritoneal membrane as a natural filter.Peritoneal Dialysis MethodsSeveral methods can be used for peritoneal dialysis, including Acute Intermittent Peritoneal Dialysis, Continuous Ambulatory Peritoneal Dialysis, and Automated Peritoneal Dialysis, also known as Continuous Cyclic Peritoneal Dialysis.Acute Intermittent Peritoneal Dialysis (AIPD) is used for patients with uremic...

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. Patient intake and output are...

Summary

Medicare Advantage patients with end-stage kidney disease use larger dialysis chains, travel further, and receive slightly lower quality care compared to Traditional Medicare patients. Monitoring dialysis network adequacy is crucial as Medicare Advantage enrollment grows.

Area of Science:

  • Nephrology
  • Health Services Research
  • Health Economics

Background:

  • Traditional Medicare (TM) and Medicare Advantage (MA) are distinct pathways for end-stage kidney disease (ESKD) patients to access dialysis care.
  • Understanding differences in dialysis facility characteristics between TM and MA enrollees is essential for ensuring equitable access and quality of care.
  • The growing enrollment in MA necessitates an evaluation of dialysis network adequacy for these beneficiaries.

Purpose of the Study:

  • To compare the characteristics of dialysis facilities utilized by TM and MA enrollees diagnosed with ESKD.
  • To identify disparities in facility ownership, distance, and quality metrics between TM and MA patients within the same geographic areas.

Main Methods:

  • Utilized 20% TM claims and 100% MA encounter data from 2018.
  • Extracted publicly available data from the Centers for Medicare and Medicaid Services.
  • Compared dialysis facility characteristics (ownership, distance, quality measures) for TM and MA patients in the same ZIP codes, adjusting for patient demographics.

Main Results:

  • MA patients were more likely to use facilities owned by the two largest dialysis organizations compared to TM patients in the same ZIP code.
  • MA patients, on average, traveled further (0.15 miles) and used facilities with modestly lower quality (e.g., 0.67 deaths per 100 patient-years higher mortality rate) than TM patients.
  • Differences in facility ownership, distance, and quality, while statistically significant, were modest in magnitude.

Conclusions:

  • MA enrollees with ESKD tend to use dialysis facilities that are further away and of slightly lower quality than those used by TM enrollees in the same areas.
  • The findings highlight potential concerns regarding dialysis network adequacy for the increasing number of ESKD patients enrolled in MA plans.
  • Continued monitoring of dialysis facility access and quality for MA beneficiaries is recommended to ensure comprehensive care standards.
