TAM (Treatments and Medicines) NHS Highland
NHS Highland

Audience

  • Argyll & Bute HSCP and/or Highland HSCP
  • Primary and/or Secondary Care.

Management of chronic kidney disease (CKD) irrespective of stage

 

 

GFR Table

GFR Category

ACR Category (mg/mmol)

A1 <3
Normal to mildly increased

A2 3 to 30
 Moderately increased

A3 >30
Severely increased

G1 >90

Normal and high

 No CKD in the absence of markers of kidney damage

Manage in primary care according to recommendations

Refer to renal unit if the person has

  • A sustained decrease in GFR of 25% or more and a change in GFR category or sustained decrease in GFR of 15 ml/min or more within 12 months
  • Hypertension that remains poorly controlled 
  • despite the use of at least 4 antihypertensive drugs
  • Known or suspected rare or genetic causes of CKD
  • Suspected underlying systemic disease
  • Suspected renal artery stenosis
  • ACR > 70 mg/mmol or more unless known to be caused by diabetes and already appropriately treated
  • ACR > 30 mg/mmol and haematuria

Manage in primary care according to recommendations

Refer to renal unit if the person has any of the criteria in A2, or: 

  • ACR 70mg/mmol or more, unless known to be caused by diabetes and already appropriately treated
  • haematuria

G2 60 to 89

Mild reduction related to normal range for a young adult

G3a
45 to 59

Mild to moderate reduction

G3b
30 to 44

Moderate to severe reduction

G4 15 to 29

Severe reduction

 Refer for specialist assessment

G5 <15

Kidney failure

SGLT 2 inhibitors

Use as per the SMC approval

Dapagliflozin in patients with Chronic Kidney Disease

SMC restriction:

  • in patients with an estimated glomerular filtration rate >25 to < 75 ml/min at treatment initiation
  • are receiving an ACE inhibitor or ARB (unless they are not tolerated or contraindicated) and
  • have a urine albumin: creatinine ratio of at least 23 mg/mmol or type 2 diabetes or both

Renal complications

  • Measure serum calcium, phosphate and PTH in people with GFR < 30 ml/min
  • Check haemoglobin in people with GFR < 45ml/min
  • Consider oral bicarbonate supplementation in patients with GFR < 30 and bicarbonate < 20 mmol/L

Frequency for monitoring of GFR

Frequency for monitoring of GFR (number of times per year, by GFR and ACR category) for people with or at risk of CKD

This should be tailored according to:

  • The underlying cause of CKD
  • Past patterns of eGFR and ACR (but be aware CKD progression is often non linear)
  • Co-morbidites especially heart failure
  • Changes to treatment (such as ACEI/ARBs, NSAIDs, diuretics)

ACR  Albumin-to-creatinine ratio
