Key Components of a Comprehensive Management Plan for Patients with Kidney Disease

A comprehensive management plan for patients with chronic kidney disease (CKD) must include regular monitoring of kidney function, blood pressure control, medication management, lifestyle modifications, and timely referral for kidney replacement therapy when needed. 1

Regular Assessment and Monitoring

• Monitor eGFR and albuminuria at least annually for all patients with CKD 2
• Increase monitoring frequency based on CKD severity:
  • G1-G2 with A1: Annual monitoring
  • G3a with A1 or G1-G2 with A2: 1-2 times per year
  • G4-G5 with any albuminuria or any GFR with A3: 3-4 times per year 2
• For diabetic patients: Assess urinary albumin and eGFR at least annually for type 1 diabetes with duration ≥5 years and all type 2 diabetes patients 2

Blood Pressure Management

• Target systolic BP <120 mmHg using standardized measurement techniques 2
• Use ACE inhibitors or ARBs as first-line therapy for patients with albuminuria 1, 2
• Titrate ACE inhibitors or ARBs to the highest approved dose that is tolerated 1, 2
• Monitor serum potassium and creatinine within 2-4 weeks of initiation or dose change of ACE inhibitors or ARBs 2
• Avoid combination therapy with ACEi and ARBs (increases adverse effects without additional benefit) 2, 3

Glycemic Control in Diabetic Kidney Disease

• Use HbA1c to monitor glycemic control in patients with diabetes and CKD 1
• Set individualized HbA1c targets ranging from <6.5% to <8.0% based on patient factors 1
• Medication selection for diabetic kidney disease:
  • SGLT2 inhibitors for patients with eGFR ≥20 mL/min/1.73 m² 2
  • Metformin as first-line therapy for type 2 diabetes with eGFR ≥30 mL/min/1.73 m² 2
  • GLP-1 receptor agonists when glycemic targets are not achieved with metformin and SGLT2i 2
  • Finerenone for patients with persistent albuminuria despite first-line therapy 2

Lifestyle Interventions

• Diet recommendations:

  • Individualized diet high in vegetables, fruits, whole grains, fiber, legumes, plant-based proteins, unsaturated fats, and nuts 1
  • Lower intake of processed meats, refined carbohydrates, and sweetened beverages 1
  • Protein intake of 0.8 g/kg/day for patients not on dialysis 1, 2
  • Sodium restriction to <2 g per day (<5 g sodium chloride) 1, 2

• Physical activity:

  • Moderate-intensity physical activity for at least 150 minutes per week, adjusted to cardiovascular and physical tolerance 1, 2

• Smoking cessation:

  • Complete avoidance of tobacco products with referral to smoking cessation programs as needed 1, 2

• Weight management:

  • Achieve and maintain optimal BMI; consider weight loss if obese 2

Medication Management

• Review and limit use of over-the-counter medicines and dietary/herbal remedies that may be harmful 1
• Consider GFR when dosing medications cleared by the kidneys 1
• Avoid medications with nephrotoxic effects when possible 1
• Monitor therapeutic medication levels for drugs with narrow therapeutic windows 1
• For patients of child-bearing potential, review teratogenicity potential and provide reproductive counseling 1

Multidisciplinary Care Coordination

• Implement team-based care involving:
  • Nephrologist
  • Primary care physician
  • Endocrinologist (if diabetic)
  • Dietitian
  • Pharmacist
  • Nurse
  • Cardiologist (when needed) 2, 4

Kidney Replacement Therapy Planning

• Refer to nephrology if:

  • eGFR <30 mL/min/1.73 m²
  • Albuminuria ≥300 mg/24 hours
  • Rapid decline in eGFR (>5 mL/min/1.73 m²/year)
  • 5-year risk of end-stage renal disease >3-5% 2, 5

• Plan for preemptive kidney transplantation and/or dialysis access when:

  • Adults: eGFR <15-20 mL/min/1.73 m² or risk of kidney replacement therapy >40% over 2 years 1
  • Children: Between eGFR 5-15 ml/min per 1.73 m² depending on factors including age, size, and rate of progression 1

• For children, pursue living or deceased donor preemptive kidney transplantation as the treatment of choice 1

Supportive Care and Conservative Management

• Inform patients about all options for kidney replacement therapy and comprehensive conservative care 1
• Support comprehensive conservative management for patients who choose not to pursue kidney replacement therapy 1
• Provide resources for advanced care planning, especially for those with end-of-life care needs 1

Common Pitfalls to Avoid

• Therapeutic inertia: Delaying initiation of SGLT2 inhibitors or RAS blockers despite clear indications 2
• Failing to titrate RAS inhibitors to maximum tolerated dose 2
• Continuing metformin when eGFR falls below 30 mL/min/1.73 m² 2
• Discontinuing ACE inhibitors or ARBs for minor increases in serum creatinine (≤30%) in the absence of volume depletion 2
• Inadequate monitoring of kidney function and albuminuria 2, 5
• Poor coordination between specialists and primary care 4

By implementing this comprehensive management plan, healthcare providers can effectively slow CKD progression, reduce cardiovascular risk, improve quality of life, and prepare patients for kidney replacement therapy when needed.
