Positive results for glucose monitoring system
A study of a glucose monitoring system designed to eliminate the need for routine finger pricks has unveiled positive results.
Findings showed that people who used the Freestyle Libre system spent 38 per cent less time in hypoglycemia.
There was also a 40 per cent reduction in time spent in nocturnal hypoglycemia and a 50 per cent reduction in serious hypoglycemia (<55 mg/dL).
The system also reduces all measures of hypoglycemia without increasing HbA1c, which means it can safely replace the need for routine finger sticks as a tool for managing diabetes.
Professor Jan Bolinder, from the Karolinska Institutet in Stockholm and chief investigator for the study, said: “Hypoglycemia is the main barrier to attaining optimum glucose control in persons with insulin-treated diabetes.
“Moreover, hypoglycemic events can not only lead to adverse clinical outcomes including cardiovascular events and death, but they can also incur significant emergency healthcare costs.
“This clinical trial has proven that patients will test more often when they have an easier and more convenient way to do so utilising a device like FreeStyle Libre, leading them to ultimately being healthier, which is our goal for our patients.”
The device consists of a small round sensor which is worn on the back of the upper arm for up to 14 days.
It measures glucose in interstitial fluid every minute through a small filament (5 mm long, 0.4 mm wide) which is inserted under the skin and held in place with a small adhesive pad.
We cannot underestimate the power of knowledge – especially for someone who is managing a chronic condition
A smartphone-sized reader is scanned over the sensor to obtain a glucose result almost simultaneously.
The findings of the six month study called IMPACT were unveiled at the 76th Scientific Sessions at the American Diabetes Association meeting in New Orleans.
For the first two weeks of the trial, the participants wore the sensor but did not have access to their glucose results.
During the next period, when they did have access to their data, time spent in hypoglycemia was reduced by 33 per cent within two weeks.
The study also showed there was a significant increase in testing frequency with participants scanning their FreeStyle Libre sensors an average of 15 times per day.
More scanning led to more access to information about glucose levels, which will lead to users being able to take action to significantly reduce their hypoglycemia and hyperglycemia on their own.
Jared Watkin, senior vice president of diabetes care at Abbott, which makes the device, said: “The IMPACT trial confirms the importance of empowering people with the data they need to make their own choices.
“We cannot underestimate the power of knowledge – especially for someone who is managing a chronic condition.
“Our goal is to help our customers be healthier and live fuller lives, and it’s clear from this trial that FreeStyle Libre provides our customers just what they need to do that.”
