Study summary

Researchers at the Department of Intensive Internal Medicine and the Department of Endocrinology and Diabetology will conduct a study to verify the accuracy and safety of the new Syai Tag system for continuous glucose monitoring in patients in intensive internal care. Almost 150,000 people in Slovenia have diabetes, so keeping a close eye on blood sugar levels is key to preventing complications. The new sensors for continuous monitoring are available over the counter and certified as medical devices. The study will include at least 100 patients who will need blood sugar monitoring during their stay in the intensive care unit. Each patient will have two small sensors placed on each upper arm to continuously measure their blood sugar levels, but these values will not be visible to medical staff. At the same time, healthcare professionals will perform routine blood sugar measurements, and researchers will then compare the accuracy of both methods. The procedure is safe and painless, and patients will receive the same quality of care as usual.

What researchers measure

Primary outcomes

  1. Percentage of sensor functional uptime during the ICU stay.

    The proportion of time during which the CGM system continuously provided glucose data without signal loss or mechanical sensor failure.

    Time frame: From enrollment to discharge or up to 14 days.

  2. Mean Absolute Relative Difference (MARD) between CGM and arterial blood gas glucose measurements.

    Statistical comparison between CGM values and reference laboratory measurements from arterial blood to assess the accuracy of the device.

    Time frame: From admission to discharge or up to 14 days.

Secondary outcomes

  1. Impact of noradrenaline on Mean Absolute Relative Difference (MARD) between CGM and arterial glucose measurements.

    The MARD will be calculated to assess CGM accuracy compared to the gold standard (arterial blood gas). To evaluate the impact of noradrenaline, MARD will be stratified and compared between two patient groups: those receiving noradrenaline (Yes) and those not receiving noradrenaline (No). Unit of Measure: Percentage (%).

    Time frame: From enrollment to discharge or up to 14 days.

  2. CGM lifespan in ICU conditions.

    The effective duration of CGM sensor function will be evaluated and compared to the manufacturer's expected lifespan.

    Time frame: From enrollment to discharge or up to 14 days.

  3. CGM glucose measurements are comparable to arterial blood glucose measurements.

    We will measure glucose in interstitial fluid with a CGM, expressed in mmol/l, and obtain arterial blood to determine blood glucose in mmol/l, and compare the analyses.

    Time frame: From enrollment to discharge or up to 14 days.

Other outcomes

  1. Sensor reliability and failure rate.

    The frequency of CGM sensor failures (signal loss, detachment or need for replacement) will be recorded and analysed.

    Time frame: From enrollment to discharge or up to 14 days.

  2. Causes of sensor malfunction.

    Reasons for CGM sensor replacement (e.g. poor adhesion, calibration failure, mechanical damage, interference from clinical procedures) will be descriptively documented. We will count the number of sensor malfunction events.

    Time frame: From enrollment to discharge or up to 14 days.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Feb 2026 (actual). Primary completion is estimated for Feb 2027, 11 months after the start.

Of 1,583 non-industry interventional studies with no phase under Diabetes Mellitus, half reached primary completion within 23 months of starting (the median), counting those still running; a quarter within 10 and three quarters within 43. This study's planned 11 months is below that.

Counting every sponsor, half of 1,743 studies reached it within 21 months; a quarter within 9 and three quarters within 42.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 4, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
