Emergency Referrals

Important

If you believe your patient requires immediate attention, please refer the patient to the emergency department (via ambulance if necessary) or seek emergent medical advice.

Kidney transplant patients with significant intercurrent illness (eg diarrhoea and vomiting)

Acute decline in kidney function

Any acute kidney injury or significant decline in kidney function where the treating doctor believes the patient requires urgent hospital care (especially if evidence of abrupt increase in serum creatinine by > 50% of baseline)
Oliguria/anuria
Severe acute electrolyte disturbance for example:
- hyperkalemia with K+ > 6.5 mmol/L OR > 6.0 mmol/L with ECG changes
- hypokalemia with K+ < 2.5 mmol/L OR < 3.0mmol/L with symptoms
- severe metabolic acidosis (HCO3 < 15mmol/L)
Kidney transplant recipients with an acute decline in kidney function (e.g. > 20% increase in serum creatinine)
Suspected glomerulonephritis (proteinuria and haematuria) associated with acute kidney injury

Chronic kidney disease

Severe acute electrolyte disturbance for example:
- hyperkalemia with K+ > 6.5 mmol/L OR > 6.0 mmol/L with ECG changes
- hypokalemia with K+ < 2.5 mmol/L OR < 3.0mmol/L with symptoms
- severe metabolic acidosis (HCO3 < 15mmol/L)
Severe hypertension especially when accompanied with declining kidney function
Patients with severe uraemic symptoms or signs
Evidence of acute fluid overload or heart failure in a patient with known CKD
Kidney transplant recipients with acute intercurrent illness
Peritoneal or haemodialysis patients with acute issues or problems with dialysis access (eg vascular access issues or peritoneal dialysis catheter issues)
Peritoneal dialysis patients with suspected peritonitis (abdominal pain, cloudy dialysis fluid)

Cystic kidney disease

Significant cyst haemorrhage, suspected septicaemia related to cyst infection, suspected rupture of berry aneurysm

Glomerular Disease

Suspected Glomerular Disease (proteinuria and haematuria) with acutely declining kidney function or patient systemically unwell

Haematuria

Severe macroscopic haematuria

Hypertension

Severe hypertension (systolic BP >220/140~~180~~or >180/110 if under 50 years of age) with no known ischaemic heart disease, cardiomyopathy, or chronic kidney disease AND any of the following concerning features:
- headache
- confusion
- blurred vision
- retinal haemorrhage
- reduced level of consciousness
- seizures
- proteinuria
- papilloedema
- signs of heart failure
- chest pain
- acute kidney injury
- suspicion of aortic dissection
- new neurological deficits
If suspected gestational hypertension or pre-eclampsia refer patient to the emergency department of a facility that offers obstetric services where possible
If hypertension service available refer to hypertension service

Kidney Stones

Suspected urolithiasis / nephrolithiasis with infection or severe pain
Suspected urinary retention/obstruction (eg anuria, oliguria)

Proteinuria

Nephrotic syndrome (proteinuria > 3.5 grams/24 hours OR urine ACR > 300mg/mmol* or PCR > 300g/mol*) with any of the following concerning features:
- significant peripheral oedema
- signs of pulmonary oedema
- severe hypertension
- signs of DVT / PE
- infection
- acute kidney injury

Useful Management Information

*At the level of nephrotic range proteinuria, albumin accounts for 60-70% of total urinary protein. Within the CPC, ACR > 300mg/mmol OR PCR > 300g/mol has been used for simplicity and ease of application.

Refer to local HealthPathways or local guidelines

Quantifying proteinuria (Source – Tasmanian Health 2018):

Urine ACR (random or first morning) is generally a sufficient screen for albuminuria/microalbuminuria in diabetic and non-diabetic populations and is a useful test in most renal clinic referrals (first morning specimens increase specificity - but not necessary). Additional protein creatinine ratio testing can assist with diagnostic evaluation.
24-hour quantification: Where urine ACR is significantly elevated (>100mg/mmol) consideration can be given to 24-hour urine protein collections (not generally required in most low-level albuminuria but is more likely to be helpful in those with suspected nephrotic syndrome)
Low level albuminuria/proteinuria can occur transiently during fever, cardiac failure, after strenuous exercise (usually no more than trace on dipstick)
Haematuria and proteinuria present together is strongly suggestive of a glomerular source for haematuria

As per KHA guidelines, persistent significant albuminuria (ACR > 30mg/mmol) should be referred. Referral is not necessary for a urine ACR < 30mg/mmol with no haematuria.
