Dialysis01:27

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...

Internal Anatomy of the Kidney01:12

Internal Anatomy of the Kidney

1.4K
The kidneys are essential organs in the human body, performing a myriad of tasks that maintain homeostasis and overall health.
Anatomical Position and Dimensions
The kidneys are retroperitoneal organs positioned against the posterior abdominal wall on either side of the spine, roughly between the twelfth thoracic and third lumbar vertebrae. Each kidney is typically 10-12 cm long, 5-6 cm wide, and 3-4 cm thick, weighing about 150 grams.
Renal Cortex
The outermost region of the kidney is the...

Factors Affecting Renal Clearance: Renal Impairment01:17

Factors Affecting Renal Clearance: Renal Impairment

62
Renal dysfunction significantly impairs the renal clearance of drugs, leading to potential complications in drug therapy. Renal failure, which can be caused by various factors, poses a significant challenge in the elimination of drugs from the body.
One condition associated with renal failure is uremia. Uremia is characterized by impaired glomerular filtration and fluid accumulation in the body. This condition hinders the renal clearance of drugs, resulting in drug accumulation and potential...

Renal Failure: Dose Adjustments01:11

Renal Failure: Dose Adjustments

69
In patients with renal impairment, drugs undergo significant changes in their pharmacokinetics, which require dosage adjustments to ensure safe and effective therapy.
Reduced renal clearance and elimination rate are common outcomes of renal impairment. These alterations lead to a prolonged elimination half-life and an altered apparent volume of distribution for drugs. As a result, dosage adjustments are typically necessary to maintain optimal drug levels in the body.
However, dosage adjustments...

Renal Drug Excretion: Tubular Secretion01:28

Renal Drug Excretion: Tubular Secretion

153
Active tubular secretion is a robust, energy-demanding process that utilizes carrier systems to transport drugs into renal tubules. The active renal secretion systems include the organic anion transporter (OAT) for weak acids and the organic cation transporter (OCT) for weak bases. Structurally similar drugs can compete for the same transporter, potentially leading to drug accumulation and toxicity. However, this principle can be exploited therapeutically. One example is probenecid (Probalan),...

Heart Failure Drugs: Diuretics01:22

Heart Failure Drugs: Diuretics

352
Heart failure and kidney perfusion are interconnected in a complex way. Reduced renal perfusion and venous congestion are two significant factors that contribute to renal dysfunction in heart failure. The kidneys, primarily responsible for fluid balance in the body, are adversely affected due to compromised cardiac output and increased venous pressure. In response to reduced renal perfusion, the kidneys activate neurohumoral mechanisms to restore balance. However, these mechanisms can be...

Area of Science:

  • Nephrology
  • Population Health Management
  • Health Services Research

Background:

  • Chronic kidney disease (CKD) is a global health burden, causing mortality and high healthcare costs.
  • Significant gaps exist in guideline-concordant CKD care, exacerbated by racial and socioeconomic disparities.
  • These care gaps contribute to disease progression, hospitalizations, and increased mortality.

Purpose of the Study:

  • To describe the implementation of nephrology population health initiatives across the CKD spectrum.
  • To demonstrate how electronic health records can modernize CKD care delivery.
  • To highlight strategies for improving patient outcomes and reducing healthcare costs in CKD.

Main Methods:

  • Leveraging electronic health records for population health management.
  • Implementing initiatives across primary care, kidney-palliative care, kidney transplantation, and transitions of care.
