ABCD NHS England closed loop pilot audit
This audit is now
exclusively for centres and patients who took part in the NHS England
pilot which launched in 2021. For new centres and non-NHS England pilot
patients please use the new audit tool which will shortly be available.
The launch of this audit was planned to coincide
NHS England pilot of broader criteria for closed loop use in
England – namely the use of closed loop systems in people already on pump
therapy with FreeStyle Libre and a HbA1c≥69mmol/mol.
This audit is ABCD's third device related audit following the success of
nationwide FreeStyle Libre audit which launched in 2017 and
ABCD DIY-APS audit launched in July 2020.
What are Closed-Loop systems?
Closed-loop insulin delivery systems,
sometimes called artificial pancreas systems, describe a setup where an
insulin pump and continuous glucose monitor are combined with an
algorithm (often held on a smart device). The glucose readings are used
by the algorithm to make and communicate decisions on insulin dosing to
maintain glucose levels within the target range. Evidence from clinical
trials of these systems demonstrates improved time-in-range, reductions
in HbA1c, reduced hypoglycaemia and improvements in quality-of-life (see
links on the left).
About the ABCD
DTN-UK Closed-Loop audit
NHS England have recently announced
a pilot of closed loop systems in
the NHS. ABCD, having previously run several successful diabetes device
audits, is launching a national audit of closed loop systems. This audit
will provide insight into the potential benefits of these systems in a
Centres involved in the closed loop roll out can collect data using the
baseline and follow up forms either in paper or electronic format (see
links on the right). We
would encourage centres to collect data prospectively using these forms.
As of 16 September, 2021, the on-line toll is live and data can now be
added. Those who have been collecting data on the forms can now upload
their data in bulk to the online tool. The baseline and follow-up forms can also be used for
retrospective data collection of those already using closed-loop
systems and that data can also be added to the on-line tool.
Registration for ABCD NHS England closed loop pilot audit is
now closed. However we would like all who are taking part
in that audit to continue entering data on the patients they entered
already entered into that audit.
For any new patients not already in that audit whom they start on closed
loops, they should enter those patients into the new ABCD DTN-UK
nationwide closed loop audit. You can register for that audit at
As of 16 September,
the on-line tool is
available for general use. The
online audit tool will be held on the Health and Social Care Network
(HSCN - formerly called N3) – the internal NHS IT system. All data is
anonymous, encrypted and GDPR compliant. As this audit is on
it can only be accessed from an NHS computer system. The tool will
facilitate both local analysis and nationwide data analysis.
the audit – centres and sites
For this audit the concept of centres and sites is utilised in the same
way as in the other ABCD audits. Typically, a centre might be an NHS
Trust. Sites might be hospitals associated with that Trust. Designated
centre leads can download their local anonymised data for analysis.
Collect data on-line or via paper forms
The on-line audit tool is
intended to be easy to use such that live data entry in clinic is a real
option to be considered. Alternatively, if preferred, to
facilitate data collection during clinics there are paper forms which
exactly match the data that can be entered into the audit tool. The
baseline registration form should be completed alongside a follow-up
form if being completed retrospectively. You can download and print
these forms locally via the link or download the PDF and complete
electronically and save to your secure NHS drive (see links on the left
to download the forms).
The ABCD nationwide audit programme has
Caldicott Guardian approval. The programme is audit not research. The
NHS encourages audit of clinical practice and there are strict
guidelines which we follow, in particular that we only to collect data
from routine clinical practice, and analysis is of data which is
