Varying quality of technology for continuous blood glucose monitoring – forskning.se

Researchers at the Sahlgrenska Academy, University of Gothenburg, together with researchers in the United States in a clinical trial compared the safety and ease of use of two of the most popular gauges: Dexcom G4 System and Enlite Guardian REAL-Time System.

The findings, published in the scientific journal Diabetes Technology & amp; Therapeutics, shows that there are significant differences both in accuracy and in how user-friendly both sensors are experienced.

In the study, 38 people with diabetes to use both systems in four to six days. Simultaneously measured the participants’ blood sugar levels regularly with a more accurate measurement techniques. The scientifically conducted the comparison shows that the Dexcom G4 had a better accuracy and less signal interference. It was also the sensor that the majority of the participants preferred to use.

– Dexcom sensor showed higher precision than Enlite sensor when blood sugar levels were low or within the normal range. When it comes to discovering low sugar values ​​deviated Enlite sensor average of 35 percent from the actual glucose levels, compared with 20 percent for the DexCom sensor, says doctoral student Viktorija Matuleviciene who led the study.

If glukosmättekniken shows incorrect blood glucose values ​​means it is likely that the treatment will be less effective because the patient is not warned optimal for low blood sugar levels, and do not have time to correct high blood sugar levels in time.

– The major differences in treatment experience is also interesting because in previous studies found that a greater proportion of patients do not choose to use the sensor if it is felt uncomfortable or if it is distracting, which then gave poorer glucose control, says Dr Marcus Lind who also was responsible for the study.

The research study was conducted with the support of the Västra Götaland Region and the Swedish Society of Medicine, in order to evaluate the safety of medical treatments. The study was conducted independently of the companies that manufacture the sensors.
