Study summary

Pilot study to evaluate the effect of real time continuous glucose monitoring (RT-CGM) on young-adults with insulin-treated diabetes, who are defined as high risk due to suboptimal HbA1c (blood glucose control) or a history of hospital admissions for high blood glucoses.

Hypothesis: RT-CGM provided to young adults with suboptimal blood glucose control, has a beneficial impact on HbA1c and hospital admissions for high blood glucoses. We will use data from this pilot work to inform a larger powered study to address this knowledge gap.

Read the detailed description

Real time continous glucose monitoring (RT-CGM) is a technology that measures people's sugar level all the time, using a sensor that is placed on the skin. The sensor can be worn for 10 days and the small transmitter clicks into the sensor and sends the glucose readings wirelessly to a smartphone or a small handset, which displays the glucose level on the screen. It also has alarms to tell people when their sugar level is too high or too low. This study uses the Dexcom G6 RT-CGM system.

RT-CGM devices have become smaller and can connect easily with mobile phones. We want to find out whether young people, in particular, find the technology useful and whether it improves how they self-managed their diabetes over a 6-month period.

This is a randomised controlled cross over trial; participants are randomly assigned to the control group (standard care which is self-monitoring of blood glucose via fingerprick) or the intervention group (RT-CGM) for the first 6 months and then cross over for the 2nd 6 months. Participants will be able to share their CGM data if they wish via Dexcom Clarity with the research/clinical team, who will support them in making treatment decisions in light of the data.

All participants will be asked to take part in a semi-structured interview with a Diabetes Specialist Clinical Psychologist at baseline, including to address some of the barriers to self-management and a further interview at the end of the 6 months during which they use RT- CGM, to explore their experiences using it. All participants will be asked to complete validated psychology questionnaires at baseline, 6 months and 12 months. A blood test for HbA1C will be done at baseline, 6 months and 12 months. After 12 months, all participants will be invited to attend a focus group to provide feedback \& share their experiences of using RT-CGM and raise themes brought up in psychology interviews to the whole group.

Study arms

  • Experimental
    Real Time Continuous Glucose Monitoring

    Participants wear Real time continous glucose monitoring (Dexcom G6), with alarms for when their glucose is too low or too high. They will be able to view their data on the Dexcom app on their smartphones or a Dexcom receiver and share this with a nominated caregiver. Participants can chose to share data between study visits via "Dexcom clarity" with the research/clinical team, who will support them making changes to their insulin regime in light of the data.

    Device: Dexcom G6

  • Placebo comparator
    Standard care

    Standard care - finger prick self monitoring of blood glucose.

    Device: Self monitoring of blood glucose
