Trial summary

The aim of this observational study is to assess safety and implementation of continuous glucose monitors within the Intensive Care Unit. The Dexcom G7 is a continuous glucose monitoring system that shows blood glucose values in real-time and includes alarms if the glucose is very low or high. Read more about this study

About this study

The aim of this observational study is to assess safety and implementation of continuous glucose monitors within the Intensive Care Unit. The Dexcom G7 is a continuous glucose monitoring system that shows blood glucose values in real-time and includes alarms if the glucose is very low or high.

Read the detailed description

Aim: To assess safety and implementation of networked CGM with ViewsEMR® telemetry within ICU.

The study will be conducted in a two-stage process:

  • Phase 1: A single arm (non-randomised) unmasked feasibility study with adjunctive use of networked CGM using the Dexcom G7 system and ViewsEMR® telemetry. This phase will be conducted at a single site at Imperial College Healthcare NHS Trust (ICHNT).
  • Phase 2: A randomised, parallel-group pilot study with adjunctive use of networked CGM using the Dexcom G7 system and ViewsEMR® telemetry compared to standard of care. This phase will be conducted at three hospitals within the same site: ICHNT (St Mary's Hospital, Charing Cross Hospital and Hammersmith Hospital). The study will be conducted at Imperial College Healthcare NHS Trust in people with hyperglycaemia on admission to ICU requiring insulin.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Contact Parizad Avari, MBBS, PhD (020 33133706, p.avari@nhs.net), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Phase 1: Eligible participants that consent to participate. (time frame: Throughout Phase 1 study period, up to 6 months). The study lists 10 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07769138, which also lists 32 linked publications.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
