Is AKI really a problem?
‘
100,000 deaths are year are associated with acute kidney injury. (NCEPOD 2009)
Costs to the NHS estimated to be
£1 billion
per year.
(Kerr et al
2014)
Approximately 65% of Acute Kidney Injury Starts in the Community. (Selby et al 2012)
Slide5Acute Kidney Injury
Acute kidney injury (AKI) is the sudden and recent reduction in kidney function resulting in a inability to maintain fluid, electrolyte and acid base balance.
AKI is a syndrome that usually occurs in the presence of other acute illness such as SEPSIS or HEART FAILURE.Diagnosis of AKI is based on either the urine output or the creatinine level (or both) AND clinical assessment, history, presentation.

Slide10Treatment of AKI
Treatment of AKI is about identifying the cause and formulating a treatment plan to address this.
Usually AKI requires fluid replacement. It is therefore essential that clinical assessment of fluid status has been completed. It a patient is hypotensive and hypovolaemic IV supplementary fluid will be required.Medications may need to be with held for a few days until the acute insult is recovering.
A renal ultrasound should be considered.Fluid balance should be monitored alongside vital signs.
Dipstick Urine and document the results in the patients medical record.Referral to renal teams may be indicated if the cause of AKI is unknown, or the patients AKI is severe or not responding to treatment, or the patient has had a renal transplant. Referrals to specialities should be senior clinician to senior clinician.Patients with life threatening complications (Acidosis, Pulmonary Oedema, Hyperkalaemia or uraemia should be referred to specialist services for possible renal replacement therapy.
For further information regarding recognition and management of AKI see NICE CG169.

Slide11Top Tips for Nurses regarding Acute Kidney Injury
The kidneys play a pivotal role in the regulation of blood pressure through salt and water balance. Blood pressure that is too high or too low will ultimately lead to damage within the kidneys so its important to keep patients blood pressure within normal range.
Pre-renal AKI is often due to hypo perfusion and low blood pressure. For any patients with low blood pressure they must be assessed and discussed with the GP as they may need escalation into hospital for treatment.
Not all pre renal AKI is a consequence of dehydration. Worsening heart failure will reduce cardiac output thus resulting in a lower BP. Be aware of your patients who have established heart failure and ensure they are reviewed regularly by the GP.
For further information regarding hypertension in adults see NICE CG127 Hypertension.

2) Urinalysis might alert you to an intrinsic kidney problem.
Protein and blood should not filter through to the urine therefore if it is present on a urinalysis test this could indicate signs of renal disease.
If more than 3+ of protein or blood is present – discuss with your GP about what to do next.

4) Hydration is key.
Dehydration is the underlying cause of many common conditions including: constipation; falls; urinary tract infections; pressure ulcers; malnutrition; incontinence; confusion and pre renal AKI.
The elderly are more prone to dehydration because as we age we lost the ability to recognise thirst. Other factors such as poor mobility and reduced confidence can also affect a patients desire to keep hydrated.
Elderly patients are likely to have more co-morbidities and poly pharmacy which could be attributed to worsening AKI. Education to patients and carers regarding hydration and medications is vital.Some patients may need further support in staying hydrated. For example patients may need beakers instead or cups – or carer input to maintain fluid intake throughout the day. It could be as simple as set drink routines rather than relying on thirst alone.
Signs of dehydration include:Thirst, sunken eyes, irritability, confusion, cool peripheries, low BP, Raised HR, headaches, reduced skin turgor, dry mucus membranes.

5) Consider the Kidneys in everything you do.
The kidneys don’t usually complain.The kidneys can lose up to 90% of their function before you may even begin to notice.
The kidneys are clever organs but need a good blood supply to work effectively.
Consider the kidneys in your daily visits.Ask if your patient has passed urine?Ask if they are well hydrated.Consider if your patient has risk factors for AKI and whether further investigations such as monitoring of creatinine levels are required.
Consider if your patient has an acute insult that may warrant temporary cessation of medications.Consider further review by GP.
