Insights

Patients with chronic kidney disease (CKD) undergoing total hip arthroplasty (THA) face a higher risk of 90-day readmission. However, CKD did not significantly increase risks for revision surgery, infection, or mortality after THA.

Area of Science:

  • Orthopedic Surgery
  • Nephrology
  • Public Health

Background:

  • Chronic kidney disease (CKD) affects surgical outcomes.
  • Total hip arthroplasty (THA) is a common procedure.
  • Understanding risks for CKD patients undergoing THA is crucial.

Purpose of the Study:

  • To evaluate the risks of revision, surgical site infection (SSI), thromboembolic events, mortality, and readmission in patients with CKD undergoing THA.
  • To compare outcomes between CKD patients and those without CKD after THA.

Main Methods:

  • Retrospective analysis of 20,720 primary THA cases.
  • Identified 1269 patients (6.1%) with CKD.
  • Adjusted for demographic and comorbidity factors.

Main Results:

  • CKD patients had a 1.4-fold increased risk of 90-day readmission (95% CI 1.1-1.8).
  • No significant differences in risks for revision (aseptic, septic), SSI (deep, superficial), deep vein thrombosis, pulmonary embolism, or mortality (30-day, 90-day, ever) were observed.
  • CKD patients represent a distinct population requiring specific attention.

Conclusions:

  • CKD is associated with an elevated risk of 90-day readmission following THA.
  • CKD does not appear to significantly increase the risk of major complications like revision, infection, or mortality after THA.
  • These findings highlight the need for targeted post-discharge care for CKD patients after THA.

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...

Chronic Kidney Disease I: Introduction

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...

Acute Kidney Injury III: Clinical Manifestations

Acute Kidney Injury (AKI) progresses through distinct clinical phases: the oliguric, diuretic, and recovery phases, each marked by unique manifestations and challenges.Oliguric Phase:The oliguric phase is the initial stage of AKI, typically lasting 10 to 14 days. This phase is marked by a significant reduction in urine output, usually less than 400 mL per day, indicating decreased kidney function. Fluid retention is a prominent feature, leading to symptoms such as edema, hypertension, and...

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...

Chronic Kidney Disease II: Clinical Manifestations

Chronic Kidney Disease (CKD) progressively impairs multiple body systems due to the accumulation of uremic toxins, which disrupt cellular functions across various organs.Neurologic symptomsNeurologic symptoms often arise early in CKD, as uremic toxin buildup drives changes in cognitive and motor functions. Patients frequently experience fatigue, headache, confusion, difficulty concentrating, and, in severe cases, seizures. Peripheral neuropathy commonly manifests as burning sensations in the...

Acute Kidney Injury I: Introduction

Introduction:Acute Kidney Injury (AKI) describes a swift decrease in kidney function occurring over hours to days, characterized by the kidneys' failure to remove waste products from the bloodstream. This leads to dangerous complications like metabolic acidosis, fluid overload, and electrolyte imbalances, such as hyperkalemia, which can cause life-threatening arrhythmias. AKI is common in both hospital and outpatient settings, often triggered by dehydration, sepsis, or exposure to nephrotoxic...
