CKD In Primary Care Dr Mohammed Javid
Relevance • End Stage CKD places a very significant burden on patients quality of life. • End Stage CKD is very expensive to manage. • Deteriorating CKD is an independant risk factor for an increase in mortality from cardiovascular disease. • QOF: CKD = 38 points
Guidelines • National Service Framework 2004 -2005 • NICE guidelines 2008 • PACE local guidelines • QOF
eGFR • CKD classification is based on eGFR • Estimates Glomerular Filtration Rate using serum creatinine and patients Age, Sex, etc • Cockroft-Gault formula • MDRD formula
Creatinine 120 eGFR 31-40 eGFR 82-106
Insert P for proteinuria 3a and 3b 45-49 and 30-44 * Structural (eg APCKD), functional (eg proteinuria) or biopsy proven GN
Risks of a low eGFR Renal • 1% of patients with CKD 3 will progress to ERF in their lifetime (99% won’t) Cardiovascular • If you have an eGFR <60 you are at higher risk of all cause mortality and any cardiovascular event
1 year later: 1 patient needs RRT, 10 patients have died (> 50% CV death)
10 years later: 8 patients need RRT, 65 patients have died, 27 have ongoing CKD
Proteinuria • Indicates poorer renal prognosis • Urine dipstick • Protein : Creatinine ratio PCR • Protein : Creatinine Index PCI • Albumin : Creatinine Ratio ACR • Early morning sample • <5 normal, >30 significant , >70 severe • Check for heamaturia
Progressive CKD • Check at least 3 eGFRs over 90 days • Defined as a decline in eGFR of >5 within 1 year, or >10 within 5 years
Routine management Lifestyle modification • Smoking increases risk of progressive CKD • Lose weight if obese • Regular exercise • Reduce salt if hypertensive
Routine management Monitor eGFR • CKD 3 6 monthly • CKD 4 3 monthly • CKD 5 6 weekly
Routine management Control BP • NICE target <140/90 • <130/80 if ACR >70 • <130/80 if diabetic • QOF <140/85 for all
Routine management ACEI or ARB: • Diabetes + ACR (>30) (irrespective of hypertension or CKD stage) • Non-Diabetic with CKD + HT + ACR >30 • Non-Diabetic with CKD + ACR >70 (irrespective of presence of HT or CVD)
Routine management Routine anti-hypertensive treatment • Non-diabetic + CDK + HT + ACR <30 (See NICE Hypertension guideline 34)
Routine management CVD risk assessment • treat with a statin if CVD risk >20% (SystmOne CVD risk calculator does NOT include adjustment for chronic renal disease, but QRISK2 does) Immunizations • Influenza - annually • Pneumococcal - 5 yearly, due to declining antibody levels
Routine management Drugs • Check BNF Appendix 3: Renal Impairment Test for anaemia • If Hb <11 first consider other causes of anaemia • Determine iron status – if serum ferritin <100 start oral iron
Consider renal USS • If CKD 4 or 5 • Progressive CKD • Visible or persistent microhaematuria • Symptoms of urinary tract obstruction • FHx polycystic kidney disease and >20yrs of age
Consider referral • CKD 4 or 5 • Proteinuria ACR >70 • Proteinuria ACR>30 with haematuria • Progressive CKD • CKD and poorly controlled BP on 4 agents • Suspected genetic renal disease or renal artery stenosis
QOF indicators • CKD points total = 38 points = £££ • CKD1 (register) = 6 points • CKD2 (bp checked) = 6 points • CKD3 (bp controlled) = 11 points • CKD5 (acei started) = 9 points • CKD6 (acr checked) = 6 points
Take Home Message • CKD is an independant risk factor for cardiovascular mortality which far outweighs the risk of developing end-stage renal disease • CKD 3 is managed in primary care with ACE-i and cardiovascular optimisation. • Monitor eGFR • Blood pressure control with ACE • Check for proteinuria
