Older people with diabetes would benefit from using wearable glucose monitors – according to new research from the University of East Anglia.

The devices help people with diabetes manage their condition by reducing the need for finger-prick blood tests. But while they have been approved by the NHS, mainly for younger adults, they are not universally available.

Lead researcher Dr Katharina Mattishent, from UEA’s Norwich Medical School, said: “Older people with memory problems can find it more difficult to keep an eye on their blood sugars.
“Older methods of checking blood sugars rely on people doing finger-prick tests.
“The newest technology works by allowing a sensor inserted under the skin on the arm to pick up sugar readings all the time for up to two weeks without having to do finger-prick tests.
“The sensor reads sugar levels and transmits them wirelessly to a display on a portable reader held near the sensor – a bit like swiping a contactless bank card.
“It is estimated that up to 20% of older people with dementia also have coexisting diabetes. It’s a big problem because they may be more prone to low blood sugars (hypoglycaemia) from their medication, but not recognizing the warning signs – or what to do if it happens.
“This is the first project to see if new wearable glucose monitoring technology could be useful for older people with diabetes and memory problems.”
The research team investigated whether using the Freestyle Libre flash glucose monitoring system could help older people with memory problems manage their diabetes.
They trialled the device with 12 participants who were experiencing memory problems, or who had been diagnosed with dementia. The average age of participants was 85.
The devices captured data across 14 days and the research team interviewed the participants and carers to see how they got on with using the devices.
Prof Yoon Loke, also from UEA’s Norwich Medical School, said: “Our study found that older people and their carers overwhelmingly found the device to be acceptable to use and reassuring to be able to check sugar levels more easily.
“One of the carers said that it is very stressful to have to regularly stab her husband’s fingers to get blood samples. He had dementia and diabetes, and couldn’t understand why anyone needed to hurt him with a needle.
“One problem we found though was that data recorded was not always complete because it relied on participants or their carers ‘swiping’ three scans a day. Real-time devices that automatically record and send the data through Bluetooth may therefore be even more beneficial for people with memory problems.:
Dr James Pickett, head of research at Alzheimer’s Society, said: “We’re delighted to see our funded research demonstrating possible benefits of wearable technology for some people with diabetes. Many people with dementia have other health conditions, and managing them all together can be challenging. It’s exciting to see that technology may be part of the answer. The next step is to test the impact in a larger group of people.
“Devices which continuously monitor people with dementia could help keep them out of hospital, preventing unnecessary distress, and saving the NHS money. While research for new drugs is vital, studies like this are just as crucial, which is why we are currently funding £15 million of care research that could offer more immediate impact of improving health and quality of life.”
‘Continuous glucose monitoring in older people with diabetes and memory problems: a mixed-methods feasibility study in the UK’ is published in the journal BMJ Open on November 19, 2019.
