Chronic kidney disease

ICD-10 N18 · Chronic kidney disease (CKD)

Monitoring plan

National Institute for Health and Care Excellence (NICE) (2024) · NICE NG203

taking medicines that can adversely affect kidney function · at least annually

“Monitor GFR at least annually in adults, children and young people who are taking medicines that can adversely affect kidney function, such as: calcineurin inhibitors, lithium, non-steroidal anti-inflammatory drugs (NSAIDs)” — NG203

eGFR

routine monitoring, NG203 Table 2 · 0 to 4 times a year depending on GFR and ACR category

“G1-G2 (>=60): 0-1x/year to 1-2x/year; G3a: 1x/year to 2x/year; G3b: 1-2x/year to 2-3x/year; G4: 2x/year to 3x/year; G5 (<15): 4x/year or more” — NG203 Table 2

Albumin/Creatinine

adults with CKD · matches eGFR frequency; confirm ACR 3-70 mg/mmol with an early morning sample

“Use urine ACR rather than protein:creatinine ratio (greater sensitivity for low levels). If ACR 3-70 mg/mmol: confirm with early morning sample” — NG203

Potassium

starting a renin-angiotensin system antagonist · before starting a RAAS antagonist, 1 to 2 weeks after starting, and after each dose increase

“Measure serum potassium and eGFR before starting. Repeat measurements 1-2 weeks after starting. Repeat after each dose increase” — NG203
