Research summary
Continuous glucose monitoring (CGM) devices are often used to check blood sugar levels in people with type 1 diabetes and some people with type 2 diabetes. However, we yet don't know how useful they are for very sick people in hospital. Currently, hospitals use finger prick or blood samples to check glucose levels, which can be painful, and are only done at certain times, rather than continuously.
This research aims to see if using CGM in an NHS intensive care unit (ICU) helps manage glucose levels in very sick people on insulin. CGM devices provide a continuous recording of glucose every 5 minutes, and data will be displayed on a screen so that staff at the ICU unit can easily see glucose levels and make necessary adjustments to insulin treatment.
This is a pilot study to assess the feasibility and acceptability of using networked CGM within the ICU. It will be conducted in two phases.
In the first phase, people with high sugar levels and admitted to ICU will wear the Dexcom G7 CGM system in addition to standard care. CGM data will be automatically uploaded and viewed by the nursing team at the bedside and central monitoring station (via ViewsEMR® telemetry system). The aim is to evaluate feasibility and whether the system will work.
The second phase is a randomised pilot study. Up to 50 adults will be recruited, aiming for 40 adults to be completed. Participants will be randomised to the “intervention group” (as described above) or the “control group consisting of usual care only” for the duration of their stay on ICU. For those in the “control group”, they will have “masked CGM” using a receiver. Although nursing staff will be unable to view their CGM data in real-time, we will later analyse this to assess which group did better.
