‘It is morally inexcusable that people – mostly young people – still die of untreated acute kidney failure.’
President Giuseppe Remuzzi
ISN 0 by 25 Initiative
This initiative has one clear and concise aim: that no one should die of untreated acute kidney failure in the poorest parts of
Africa, Asia and South America by 2025

Strippoli et al J Am Soc Nephrol 2004
• Nephrology has a poor record of RCTs – fewest of all internal medicine specialties
• 1.5% of publications were RCTs (3rd lowest)
• Quality of reporting is low

Quality Standard
AKI quality standard being developed
Concise set of statements designed to drive measurable quality improvements
e.g Patients at risk of AKI who suffer acute illness should have their creatinine measured

Opportunity
• Harmonise the measurement of AKI • Characterise the epidemiology
– identify those at risk of AKI
• Data for major research – attract big Pharma
• Collaborate to refine the methodology
• No other country able to achieve • Bruce Molitorus
– ‘if you can shame the USA into trying to achieve this then so be it’

Caveats • Not all NHS Trusts have the same method of measuring
creatinine – enzymatic, Jaffe
• AKI defintion – algorithm will not detect all patients with AKI – importance of urine output (NEWS), clinical skill
• Not all patients with small rises in creatinine will have AKI – ascertainment
• E-detection systems will not determine the cause of AKI – syndrome
• E-detection systems will detect those with AKI already developing – need to identify those at risk

Primary Aim
The primary aim of the National Programme is to ensure avoidable harm related to AKI is prevented in all care settings.

The purpose of the National Programme is to deliver and implement a structure and tools within three years that will lead to a fall in the number of preventable episodes of AKI, and with that a reduction in deaths associated with AKI. It will lead work on the development of clinical tools, information and levers and prioritise patient empowerment. It will utilise commissioning pathways and other clinical networks. It will also establish local and national data collection and audit leading to further safety improvement and target research towards areas that require elucidation.

RCPE Consensus Statement November 2012 • Identification of AKI in both primary and secondary care
should be facilitated through introduction of e-alert systems
• At present systems are being developed ad hoc
• A national group should be established to develop agreed standards for e alert systems recognising the need for some system dependent local flexibility. Components of the system should include an agreed definition of AKI based on the KDIGO classification and a standardised methodology for derivation of baseline serum creatinine. We recommend use of an enzymatic serum creatinine assay with an IDMS Traceable calibration to enable standardisation.

Consensus AKI Warning Algorithm Meeting July 2013
• Held at the invitation of the Association for Clinical Biochemistry and Laboratory Medicine
• Nephrologists appointed by Richard Fluck renal CD at NHS England
• Clinical Biochemistry representation from England Scotland and Wales
• Lab Computer suppliers invited via a poll of ACB members
• The output of the meeting was a consensus algorithm that was not identical to any of the algorithms in use at the time

Local Flexibility • The AKI programme is intending to implement
the standardised AKI warning algorithm
• Local versions of an AKI warning algorithm even when developed to accomodate limitations of the local Pathology computer system (LIMS) will not be compliant with the AKI Programme
• Local flexibility will be necessary to convert an AKI warning into an alert (digital or analogue)

Issues with Implementation
• Older versions of LIMS systems may require a major software (possibly hardware) upgrade
• Existing algorithms established locally may contain innovations that should not be discarded.
• Concerns about validation of external algorithms
![Page 55: Acute Kidney Injury (AKI) Scientific Day 19 June 2014 11.00-15annually from AKI People per year get AKI during a hospital stay 5 22 Your length of stay in the hospital increases by](https://reader033.fdocuments.in/reader033/viewer/2022051810/60167c857b44123d673bee84/html5/thumbnails/55.jpg)
Why does the AKI warning algorithm need to be standardised?
• Removes an important variable facilitating comparative research (The RCPE Consensus Conference : We recommend audit and research to confirm that in addition to identification of AKI the use of e-alert systems improves outcomes)
• Allows co-ordinated stepwise improvement of the AKI warning algorithm

Safety alert (issued 9/6/14)
• Raises profile of AKI and the need to develop systems to detect early and treat
• Gives laboratories a clear idea of what to demand from their LIMS suppliers
![Page 59: Acute Kidney Injury (AKI) Scientific Day 19 June 2014 11.00-15annually from AKI People per year get AKI during a hospital stay 5 22 Your length of stay in the hospital increases by](https://reader033.fdocuments.in/reader033/viewer/2022051810/60167c857b44123d673bee84/html5/thumbnails/59.jpg)
Maintaining and modifying the algorithm
• A sub-group of the detection workstream will consider suggestions for changing the algorithm and supervise future pilots
• Updates of the algorithm will be issued infrequently (maximum frequency 1 year) to allow stepwise adoption by LIMS suppliers ad their clients.

The AKI Detection Workstream Programme - What it is not about
• Ignoring innovation
• Intransigence to change
• Neglecting existing good practice
• Imposing a Tertiary Care model
![Page 61: Acute Kidney Injury (AKI) Scientific Day 19 June 2014 11.00-15annually from AKI People per year get AKI during a hospital stay 5 22 Your length of stay in the hospital increases by](https://reader033.fdocuments.in/reader033/viewer/2022051810/60167c857b44123d673bee84/html5/thumbnails/61.jpg)
What the detection workstream is about
• Reducing variation in the detection of AKI between Trusts
• Providing a firm basis for outcome research
• Providing information resources to enable Trusts to implement the national AKI programme
• Continuous stepwise improvement of the AKI algorithm in co-operation with LIMS providers

Group Work
13.15 - 13.55
Instructions
We have set a question for each of the 6 groups to answer. The question can be found in your group. You have 40 minutes to debate this question in your group. Be prepared to provide a five minute highlight presentation to feedback to the whole group. You will find flipcharts and pens in your groups.

Group Question
1 How would you advise a hospital that is planning to implement an AKI detection system? Would this be different for hospitals with and without renal units on site?
2 How could a best practice recommendation for converting an AKI report into an alert be developed - what would it say and what are the different options?
3 Detection of AKI also incorporates 'case finding' to ensure blood tests are actually taken in at risk groups. How can you facilitate this in clinical practice in primary care, secondary care and care home settings?
4 As AKI detection becomes more widespread, how can we continue to share experiences, good practice and problems encountered on a national basis?
5 In the absence of an automatic alert system being present, how should an AKI test result be acknowledged by clinicians? How would the transition for labs telephoning clinical areas in hospitals with significant serum creatinine changes to an AKI risk report be handled?
6 For audit/research purposes, how should a baseline AKI detection rate be established before introducing the AKI detection algorithm? How would you design an audit for those hospitals who are yet to introduce the algorithm to measure the impact of its introduction?
