🎉 Real-time CGM is coming for NHS T1Ds!

We look at 6 CGM systems that could be available on the NHS in 2022.

This blog is particularly focussed on sensor wearers in the UK and particularly those who are able to access CGMs through the NHS. But, it should also be useful for those outside of the UK looking to assess which CGM may be suitable for them.


In November 2021, the NICE Guidelines (which determines what medicines and medtech is used by the NHS) was updated in relation to the use of continuous glucose monitors (CGM). These are currently published as a draft for consultation, but from April 2022 they are expected to come into place and are set to bring big changes for T1Ds.

It looks like there will be 6 options to choose from if you're wearing just a CGM as a standalone device ie. not with a pump and the options of which CGMs will be available  are listed on the NHS Supply Chain list of products, issued in December 2021.

The six options are: FreeStyle Libre 3, Dexcom G6, GlucoMen Day, Touchcare Nano, Guardian Connect & MeiQi.

A quick word about Libre 3 

The big change is that FreeStyle Libre 3 and these options won't be available in the usual way through a GP's prescription, but details of how patients get access has not yet been released. It looks like it has to come through hospital diabetes teams. Abbott have stated that Libre 3 is not to be considered as an upgrade from Libre 2 in the same way as moving from Libre 1 to 2. A statement for the company indicated that Libre 3 was for the management of more "complex diabetes". 

This may sound like a barrier to access but in fact is set to shake-up the landscape for type 1's as the person behind the changes - Professor Partha Kar, Diabetes Specialist for the NHS in England - has assured the community on Twitter that real-time CGMs are coming for all T1s and that they'll be a choice of device! On the face of things, this is a complete change in the approach for T1s who will be offered a real-time CGM as a matter of routine. Hurrah!

What do the updated NICE Guidelines say?

It is understood that CGMs will be offered (note, this is an update to the term 'considered' previously used in the Guidance) on par with Libre 1/2 (referred to as 'flash' devices) for T1 adults, and in the case of children and young adults CGM will be the first option, ahead of Libre. There will also be the option for some T2s to get a flash device.

This is reflected in the NICE Guideline (NG17) which state:

An adult with type 1 diabetes should be offered a choice of a real-time cgm or ‘flash’ device based on their individual preferences, needs, characteristics, and the functionality of the devices available.


The NICE Guidelines give the following factors to be considered when choosing a CGM:

  • Whether the device provides predictive alerts or alarms and if these need to be shared with anyone else, for example a carer.
  • Whether using the device requires access to particular technologies (such as a smartphone and up-to-date phone software).
  • How easy the device is to use and take readings from, including for people with limited dexterity.
  • Fear, frequency, awareness and severity of hypoglycaemia.
  • The person’s insulin regimen or type of insulin pump, if relevant (taking into account whether a particular device integrates with their pump as part of a hybrid closed loop or insulin suspend function).
  • Whether, how often and how the device needs to be calibrated.
  • Whether data can be extracted and shared with the person’s healthcare provider.
  • How unpredictable the person’s blood glucose levels are and whether erratic blood glucose is affecting their quality of life.
  • Whether the person has situations when symptoms of hypoglycaemia cannot be communicated or can be confused, for example during exercise.
  • Clinical factors that may make devices easier or harder to use.
  • Frequency of sensor replacement.
  • Sensitivities to the device, for example local skin reactions.
  • Cosmetic factors.
