Type 2 Diabetes: Continuous Glucose Monitors

Question

14:58:00

Asked by

To ask His Majesty’s Government how they intend to monitor access to continuous glucose monitors for people with type 2 diabetes; and how such monitoring will take account of any inequalities based on deprivation and ethnicity.

My Lords—

Hear, hear!

I could get used to that reception, but I am not sure that I will get used to three Questions and a repeat UQ. However, I thank your Lordships’ House. More than 200,000 eligible people living with diabetes currently benefit from real-time CGM, or continuous glucose monitoring. CGM data-reporting systems are being developed to aid the delivery of rollout by integrated care boards. Alongside this, the data is collected as part of the national diabetes audit. From 2025-26, NHS England plans to publish that data routinely on the audit’s quarterly dashboard, which will provide the insights that ICBs need, including data on CGM uptake, variation and health inequalities.

Many more people with type 2 diabetes could benefit from this technology. People living in deprivation and people of black and south Asian ethnicity are more likely to develop type 2 diabetes, are less likely to receive essential diabetes care and experience worse health outcomes. However, according to Diabetes UK, only 24 of 42 integrated care boards in England have a policy for continuous glucose monitoring for people with type 2 diabetes that is in line with guidance from NICE. How will the Government ensure equal access to such monitors for people with type 2 diabetes?

The noble Lord makes a very fair observation. Work is going on in a wider equality monitoring programme exploring how to keep an eye on equality repercussions, including ethnicity, by reference to protected characteristics in the Equality Act 2010. Importantly to the point he raised, the review includes consideration of how NHS ethnic group categories can be updated. The outcome of the review—this is the point I really want to emphasise—will ultimately guide a process of reducing inequalities, but I accept his challenge and his point.

My Lords, there is a strong link between body mass index, BMI, and type 2 diabetes. People with a body mass index of 25 to 30 have an 8% chance of developing type 2 diabetes; those with 30 to 40 have a 20% chance; and those with a body mass index of 40 or over have a 40% chance. One way of monitoring long-term glycaemic glucose levels is to measure haemoglobin A1C. It might therefore be an idea to use haemoglobin A1C levels to diagnose early type 2 diabetes, initially in people with a BMI of 40 or over, as a screening tool. It might be an idea to ask NICE or the screening committee to evaluate that likelihood.

The noble Lord makes a helpful point. I can tell your Lordships’ House that diabetes testing is included as part of the NHS health check. If a person is identified as being at high risk of type 2 diabetes, they should be offered a blood sugar glucose test or a fasting glucose test. NICE produces guidelines on preventing type 2 diabetes in people at high risk, and that includes recommendations on risk assessments, including blood testing, which can include people with a high BMI. His point is extremely valid, some of that is in place and we will ensure that it continues.

My Lords, I am sure the Minister agrees that access to a GP is critical, whether that is in detecting and monitoring diabetes or, in relation to the first Question, detecting and monitoring cancer. Would she be surprised, therefore, that in Northern Ireland it is almost impossible to access a GP at present? Indeed, it is at an all-time low. Will she consider doing a comparative study across the United Kingdom to look at access to GPs because, unfortunately, I believe it is not a very good story at all.

I hear what the noble Baroness says and I am glad to report that I met the Northern Ireland Health Minister recently, along with colleague Peers, to discuss a range of matters including differences across the nations. I will consider the point that she makes.

My Lords, while the original Question was about type 2 diabetes—as the noble Lord, Lord Patel, said, type 2 diabetes can be due to lifestyle and can sometimes be reversed—I want to ask the Minister about type 1 diabetes. Its exact cause is unknown and people can get it at any time of their life, yet there is no cure, so in some ways the need for CGM is more critical. The charity Breakthrough T1D, which represents type 1 diabetics, finds that black, Asian and minority ethnic groups in England and Wales and lower socioeconomic communities are much less likely to get access to or use these technologies. Closing that gap was one of the issues that we grappled with in government, so can the Minister tell the House what plans there are to ensure that as many type 1 diabetes patients as possible across England receive access to continuous glucose monitoring?

It is probably important to say at the outset that type 1 diabetes, as the noble Lord knows, is not related to lifestyle issues, and at this point cannot be prevented, so it is a case of management. The technology that is available now is quite remarkable— not just the CGMs that the noble Lord, Lord Rennard, inquired about, but also hybrid closed loop systems, where the CGM is paired with an insulin pump, so it is administered automatically without the person having to calculate. I think that is incredibly helpful. It is only available to those eligible, with type 1 diabetes, but the rollout began in April 2024. The noble Lord makes a good point, as did the noble Lord, Lord Rennard, about access and inequality in access. That is something we continue to work on, ensuring that everybody can fairly access these wonderful technology advancements.

My Lords, women with type 2 diabetes face a higher risk of miscarriage, stillbirth, neonatal deaths and birth defects. As we have heard, women who live in areas of high deprivation as well as women who come from black and minority ethnic groups are more likely to be impacted by type 2 diabetes. This compounds the existing inequalities in the maternal mortality rate. What steps are the Government taking to support integrated care boards to build relationships with these women who are most likely to experience these impacts, to ensure that they have the best maternity care and diabetic care, including ensuring they have access to continuous glucose monitoring where necessary?

The right reverend Prelate is quite right in what she says, including that responsibility for CGM implementation rests with integrated care boards. It is their responsibility to ensure that the technologies we are talking about can be accessed by all eligible patients regardless of their ethnicity or their indices of multiple deprivation. I assure the right reverend Prelate that achieving that equality of access in all diabetes technology is an absolute priority. We will continue to monitor progress and encourage ICBs to do that by the NDA quarterly dashboard in 2025-26. In other words, we will give ICBs the tools to do the job they need to do.

My Lords, the use of CGMs makes diabetes easier to manage, as they give not only instant information about blood sugar levels but also indicate whether levels are rising or lowering. The DVLA, however, insists on two-hourly glucose monitoring by the traditional finger pricking method when driving on long journeys. Does the noble Baroness envisage a change in this guidance in the near future?

I must confess that is something that I will need to look into—it may be with my ministerial colleagues in the Department for Transport. But I will look into it, and I will be pleased to write to the noble Baroness.

My Lords, as part of ongoing research, would my noble friend talk to her ministerial colleagues about possible research that is required into the causes of type 1 diabetes, and if more updated research could therefore provide new types of technologies and treatment? There is no particular cure at this moment in time, and people live with it on a daily basis, hour by hour.

Through the National Institute for Health and Care Research, £206 million was awarded to diabetes research in the last five years through its research programme. The NIHR and Diabetes UK have developed a joint strategy which will inform diabetes research in the UK. I hope that can get us to the place that my noble friend refers to.
