Factors That Worsen Kidney Disease Progression in Hospitalized Patients

Key Modifiable Risk Factors

  • Inadequate dialysis clearance is the most significant factor worsening kidney disease progression in hospitalized patients, with low creatinine clearance directly associated with prolonged hospitalization and increased mortality, according to the American Journal of Kidney Diseases 1, 2
  • Low creatinine clearance is associated with increased overall hospitalization rates and prolonged hospital stays in patients with kidney disease, as reported by the American Journal of Kidney Diseases 1
  • Inadequate dialysis is directly related to uremic symptoms such as nausea, vomiting, and gastrointestinal bleeding, which can worsen kidney function, as stated in the American Journal of Kidney Diseases 2
  • Suboptimal ultrafiltration and total solute clearance negatively impact technique survival in peritoneal dialysis patients, according to the American Journal of Kidney Diseases 1
  • Metabolic acidosis contributes to malnutrition and protein depletion, accelerating kidney function decline, as found in Clinical Nutrition 3
  • Hyperglycemia and insulin resistance are associated with increased risk of complications in critically ill patients with acute kidney injury/disease, as reported in Clinical Nutrition 4
  • Cardiovascular disease is the most frequent cause for hospitalizations among hemodialysis patients (33.68%) and a major cause in peritoneal dialysis patients (28.77%), according to Kidney International 5
  • Elevated blood pressure is a key modifiable risk factor for CKD progression, as stated in Kidney International 6

Non-Modifiable Risk Factors

  • Age, race/ethnicity, and genetic factors influence kidney disease progression, as reported in Kidney International 6
  • History of cardiovascular disease increases risk of CKD progression, according to Kidney International 6
  • Patients with diabetes have a higher prevalence among peritoneal dialysis patients (33.33%) compared to hemodialysis patients (25.71%), as found in Kidney International 5
  • Ongoing exposure to nephrotoxic agents accelerates kidney disease progression, as stated in Kidney International 6
  • Malnutrition is prevalent in 11-54% of patients with non-dialysis CKD stages 3-5, and between 28-54% in patients undergoing chronic hemodialysis, as reported in Clinical Nutrition 3
  • Progressive depletion of protein and/or energy stores is often observed in CKD patients, with prevalence rates increasing along with declining kidney function, according to Clinical Nutrition 3
  • Medical nutrition therapy should be provided to any patient with acute kidney injury/disease or CKD staying in the ICU for more than 48 hours, as recommended in Clinical Nutrition 3

Prevention Strategies

  • Angiotensin receptor blockers (ARBs) or angiotensin-converting enzyme inhibitors (ACE-Is) should be used in both diabetic and non-diabetic adults with CKD and urine albumin excretion >300 mg/24h, as recommended in Kidney International 6
  • Define CKD progression based on decline in GFR category, a 25% or greater drop in eGFR from baseline, or a sustained decline in eGFR of ≥5 ml/min per 1.73 m²/year, as stated in Kidney International 6
  • Categorize hospitalizations according to whether they are related to ESRD or not for better analysis and management, as recommended in the American Journal of Kidney Diseases 1
  • Medical nutrition therapy should be considered for any patient with acute kidney injury/disease, acute kidney injury on CKD, or CKD with or without kidney failure requiring hospitalization, as stated in Clinical Nutrition 3

Pitfalls and Caveats

  • Small fluctuations in GFR are common and not necessarily indicative of progression, as reported in Kidney International 6
  • Changes in eGFR may be due to true change in GFR or due to changes in the non-GFR determinants of creatinine concentrations, as stated in the American Journal of Kidney Diseases 7
  • It is essential to differentiate between progression of chronic disease and acute injury, as their definitions and management differ, according to the American Journal of Kidney Diseases 7
  • Modest increases in creatinine in the setting of effective decongestion therapy for acute heart failure are not necessarily associated with worsened outcomes, as found in Circulation 8
