The FreeStyle Libre flash glucose monitor became available on prescription(subject to local health authority approval) in all four nations of the UK fromNovember 2017, a watershed moment in the history of diabetes care. Calibrationfree, the FreeStyle Libre is a disc worn on the arm for 14 days which is designedlargely to replace the recommended 4-10 painful finger-stick blood glucose tests required each day for the self-management of diabetes. This review discussesclinical data from randomized and observational studies, considers deviceaccuracy metrics and deliberates its popularity and the potential challenges thatthis new device brings to diabetes care in the UK. In randomized trials,FreeStyle Libre use is associated with a reduction in hypoglycaemia and, inobservational studies, improvements in HbA1c levels. User satisfaction is highand adverse events are low. Accuracy of the FreeStyle Libre is comparable tocurrently available real-time continuous glucose monitors in adults, children andduring pregnancy; the cost of the FreeStyle Libre is lower. Glucose data can bevisualized in multiple devices and platforms, and summarized in an ambulatoryglucose profile to aid pattern recognition and insulin dose adjustment. There is a need for appropriate education, of both users and Continue reading >>
Freestyle Libre Flash Glucose Monitoring System
FreeStyle Libre Flash Glucose Monitoring System FreeStyle Libre Flash Glucose Monitoring System The FreeStyle Libre Flash Glucose Monitoring System is a form of continuous glucose monitor that requires the user to scan the sensor to obtain current glucose readings. It does not require routine finger sticks for calibration or for insulin dosing. This system, designed by Abbott, received FDA approval in September 2017. It is intended to help adults with diabetes achieve better glucose control without the need for finger sticks. It is expected to be available in the U.S. by the end of 2017. 4 Who Should Not Use the FreeStyle Libre System Similar to other CGMs, the FreeStyle Libre is a small, round plastic device (called a patch) that adheres to the skin and contains a sensor, which is inserted into the skin. The sensor is a tiny filament (0.2 inches in length, about the thickness of a hair, according to a review on Diatribe ) that penetrates the top layers of skin and reads the glucose levels in the interstitial fluid, rather than in the blood directly. Insertion of the sensor is simple and painless. The FreeStyle Libre is only approved to be placed on the back of the upper arm. Other CGMs are often worn on other areas of the body, such as the abdomen, but that is discouraged with this system at this time. Apparently, the sensor may not function properly if placed in other areas. In addition to the sensor, the system includes a reader, which scans the sensor using NFC technology to receive glucose level readings from it. You simply hold it close to the sensor (within 1.5 inches) to initiate the scan. It can read through clothing, as well, which allows for more discreet testing. The scan takes about three seconds. You can scan the sensor an unlimited amount of times during Continue reading >>

The Performance Of Flash Glucose Monitoring In Critically Ill Patients With Diabetes.
The performance of flash glucose monitoring in critically ill patients with diabetes. Department of Intensive Care, Austin Hospital, Melbourne, VIC, Australia. [email protected] Department of Intensive Care, Austin Hospital, Melbourne, VIC, Australia. Department of Endocrinology and Diabetology, Austin Hospital, Melbourne, VIC, Australia. Crit Care Resusc. 2017 Jun;19(2):167-174. OBJECTIVE: Frequent glucose monitoring may improve glycaemic control in critically ill patients with diabetes. We aimed to assess the accuracy of a novel subcutaneous flash glucose monitor (FreeStyle Libre [Abbott Diabetes Care]) in these patients. METHODS: We applied the FreeStyle Libre sensor to the upper arm of eight patients with diabetes in the intensive care unit and obtained hourly flash glucose measurements. Duplicate recordings were obtained to assess test-retest reliability. The reference glucose level was measured in arterial or capillary blood. We determined numerical accuracy using Bland- Altman methods, the mean absolute relative difference (MARD) and whether the International Organization for Standardization (ISO) and Clinical and Laboratory Standards Institute Point of Care Testing (CLSI POCT) criteria were met. Clarke error grid (CEG) and surveillance error grid (SEG) analyses were used to determine clinical accuracy. RESULTS: We compared 484 duplicate flash glucose measurements and observed a Pearson correlation coefficient of 0.97 and a coefficient of repeatability of 1.6 mmol/L. We studied 185 flash readings paired with arterial glucose levels, and 89 paired with capillary glucose levels. Using the arterial glucose level as the reference, we found a mean bias of 1.4 mmol/L (limits of agreement, -1.7 to 4.5 mmol/L). The MARD was 14% (95% CI, 12%-16%) and the pr Continue reading >>
Flash Glucose Monitoring
Flash Glucose Monitoring is a small sensor that you wear on your skin. It stores your blood glucose (also known as blood sugar) levels continuously and you can access them by scanning the sensor whenever you want to. A sensor that sits just underneath your skin and measures your sugar levels A reader that you swipe over the sensor to get both your blood glucose level and the trend of your levels Each time you scan your sensor, you can access the last eight hours sugar levels. Flash Glucose Monitoring also comes with software so you can analyse your results and see patterns in your blood sugar levels. You generally wear a sensor for about 14 days, after that you need to insert a new one. The sensor doesnt actually measure your blood sugar level, it measures the amount of glucose in the fluid that surrounds your body cells (called interstitial fluid). Glucose levels in the interstitial fluid lag behind glucose levels in your blood by up to 5 minutes, and the lag time is longest if your blood sugar level is changing rapidly, eg after eating or if you are exercising. For this reason you need to do a finger prick blood sugar check if youre thinking of changing your treatment (eg taking more insulin or treating a hypo). You dont need to calibrate a Flash glucose monitor. Whats the difference between Flash Glucose Monitoring and Continuous Glucose Monitoring? CGM monitors your blood sugar level continuously and sends data to your display device (a hand held monitor or pump). So you can set alerts for high, low or rate of change. With Flash Glucose Monitoring its only when you scan your sensor that you get your reading and trends. Advantages of using a Flash Glucose Monitor: You dont need to do so many finger prick checks. You can see trends: when your blood sugar levels are s Continue reading >>
Real-world Flash Glucose Monitoring Patterns And Associations Between Self-monitoring Frequency And Glycaemic Measures: A European Analysis Of Over 60 Million Glucose Tests
Real-world flash glucose monitoring patterns and associations between self-monitoring frequency and glycaemic measures: A European analysis of over 60 million glucose tests Author links open overlay panel Timothy C.Dunna Users performed a mean of 16.3 glucose checks per day, well above guidelines for self-monitoring. Estimated HbA1c reduced from 8.0% to 6.7% (64 to 50mmol/mol) as scans increased from 4 to 48 per day. Time below 3.9, 3.1 and 2.5mmol/L decreased by 15%, 40% and 49% from lowest to highest scan groups. Higher rates of scanning were linked to increased time in range and reduced time in hyperglycaemia. Associations were consistent by country, but differences were found in hypoglycaemic exposure. Randomised controlled trials demonstrate that using flash glucose monitoring improves glycaemic control but it is unclear whether this applies outside trial conditions. We investigated glucose testing patterns in users worldwide under real life settings to establish testing frequency and association with glycaemic parameters. Glucose results were de-identified and uploaded onto a dedicated database once readers were connected to an internet-ready computer. Data between September 2014 and May 2016, comprising 50,831 readers and 279,446 sensors worldwide, were analysed. Scan rate per reader was determined and each reader was sorted into twenty equally-sized rank-ordered groups, categorised by scan frequency. Glucose parameters were calculated for each group, including estimated HbA1c, time above, below and within range identified as 3.910.0mmol/L. Users performed a mean of 16.3 scans/day [median (IQR): 14 (1020)] with 86.4 million hours of readings and 63.8 million scans. Estimated HbA1c gradually reduced from 8.0% to 6.7% (64 to 50mmol/mol) as scan rate increased from Continue reading >>

Freestyle Libre
Tweet The Abbott FreeStyle Libre has come as an entirely new concept in glucose monitoring by providing much greater data than blood glucose testing whilst being more affordable than continuous glucose monitors (CGM). The FreeStyle Libre provides ‘flash glucose monitoring’ with glucose readings provided by scanning a sensor rather than pricking your finger. What are the benefits of FreeStyle Libre? Due to way the Libre works, there are a number of benefits: Reduced need to take so many blood glucose tests Provides graphs of how your sugar levels have been varying - in a similar way to how a CGM does Scanning the sensor shows how much your results are trending upwards or downwards More affordable than a CGM Sensor is waterproof in up to 1m of metre for 30 minutes How the FreeStyle Libre works The FreeStyle Libre works by having a small round sensor applied to your arm. The sensor is a round disc, 5mm high and 35mm diameter, making it roughly the size of a £2 coin. The sensor is applied to the skin with a handheld applicator and then lasts for 14 days. Most people that were used in patient trials of the Libre rated the application of the sensor as being painless. Within the 14 days of usage, the sensor allows you to scan the sensor with the handset which sends data of your sugar levels over the previous 8 hours to the Libre system’s handset. When you scan, you therefore get not just a glucose reading, as you would with a blood glucose meter, but can also see whether your sugar levels are starting to go up, down or are stable. How much does the FreeStyle Libre cost? At the time of writing, the FreeStyle Libre is available at the following prices direct from Abbott’s FreeStyle Libre website: Starter Pack - reader plus two 14 day sensors: £159.95 FreeStyle Libre Re Continue reading >>

Another form of glucose monitoring, known as flash glucose monitoring, consists of a sensor and a reader. The sensor is placed at the back of the upper arm and once inserted, may be used for up to 14 days. Using the reader to flash across the sensor, the user is able to view: The direction in which the glucose is heading, and "Unlike real-time continuous glucose monitoring, flash glucose monitoring does not require blood glucose (fingerstick) calibrations. However, it is unable to provide alarms, and the glucose reading is only retrieved when the user flashes the reader across the sensor, explains Dr Daphne Su-Lyn Gardner , Consultant from the Department of Endocrinology , Singapore General Hospital (SGH), a member of the SingHealth group. Using the reader to flash across the sensor, the user is able to know the glucose level without the need for a finger prick. Continue reading >>
Say Goodbye To Finger Sticks: Fda Approves Abbott’s Freestyle Libre Flash Glucose Monitoring System
The U.S. FDA has approved Abbott’s FreeStyle Libre Flash Glucose Monitoring System as a replacement for blood glucose monitoring (BGM) for adults with diabetes. This revolutionary new glucose sensing technology eliminates the need for routine finger sticks and is the only personal continuous glucose monitor (CGM) that does not require finger stick calibration. Designed to be approachable, accessible and affordable for the 30 million people with diabetes in America, the FreeStyle Libre system reads glucose levels through a sensor that is worn on the back of the upper arm for up to 10 days, making it the longest lasting personal glucose sensor available in the U.S. The BGM replacement indication means that people with diabetes and their physicians can now make treatment decisions based on information from the FreeStyle Libre system, without the need for finger sticks. The cost of the Libre Flash Glucose Monitoring System is just a fraction of the cost of other CGM systems currently available. “Today, we are celebrating a breakthrough moment for people with diabetes in the U.S.–an end to the worry and hassles associated with routine finger sticks which have been the standard of glucose testing for more than 40 years,” said Jared Watkin, senior vice president, Diabetes Care, Abbott. “At Abbott, we believe that FreeStyle Libre will transform diabetes management and we’re proud to be at the forefront of innovation that empowers people to take control of their health to live their best lives.” How The Freestyle Libre System Works With the FreeStyle Libre system, people with diabetes can: Self-apply the sensor, which is approximately the size of two stacked quarters, to the back of the upper arm.

Fda Approves First Continuous Glucose Monitoring System For Adults Not Requiring Blood Sample Calibration
Release The U.S. Food and Drug Administration today approved the FreeStyle Libre Flash Glucose Monitoring System, the first continuous glucose monitoring system that can be used by adult patients to make diabetes treatment decisions without calibration using a blood sample from the fingertip (often referred to as a “fingerstick”). The system reduces the need for fingerstick testing by using a small sensor wire inserted below the skin’s surface that continuously measures and monitors glucose levels. Users can determine glucose levels by waving a dedicated, mobile reader above the sensor wire to determine if glucose levels are too high (hyperglycemia) or too low (hypoglycemia), and how glucose levels are changing. It is intended for use in people 18 years of age and older with diabetes; after a 12-hour start-up period, it can be worn for up to 10 days. “The FDA is always interested in new technologies that can help make the care of people living with chronic conditions, such as diabetes, easier and more manageable,” said Donald St. Pierre, acting director of the Office of In Vitro Diagnostics and Radiological Health and deputy director of new product evaluation in the FDA’s Center for Devices and Radiological Health. “This system allows people with diabetes to avoid the additional step of fingerstick calibration, which can sometimes be painful, but still provides necessary information for treating their diabetes—with a wave of the mobile reader.” People with diabetes must regularly test and monitor their blood sugar to make sure it is at an appropriate level, which is often done multiple times per day by taking a fingerstick sample and testing it with a blood glucose meter. Typically patients use results of a traditional fingerstick test to make diabetes Continue reading >>
Flash Continuous Glucose Monitoring And Its Impact To Replace Blood Glucose Monitoring In The Management Of Type 1 And Type 2 Diabetes
Flash Continuous Glucose Monitoring and its IMPACT to REPLACE Blood Glucose Monitoring in the Management of Type 1 and Type 2 Diabetes US Endocrinology, 2017;13(2):5762 DOI: Objective: Established methods of self-monitoring of glucose levels include capillary self-monitoring of blood glucose (SMBG) and interstitial continuous glucose monitoring (CGM). Flash CGM is a novel form of self-monitoring that provides on-demand continuous interstitial glucose profiles. The purpose of this article is to critically review the recent outcome data from randomized controlled trials that assessed the efficacy and safety of flash CGM to replace routine SMBG in diabetes management. Methods: Two recent six-month, prospective, multicenter, randomized controlled trials in type 1 (IMPACT; NCT02232698) and type 2 (REPLACE; NCT02082184) diabetes compared flash CGM with SMBG under otherwise usual care conditions. The trials did not use a prescribed treatment algorithm based on self-monitoring of glucose. Results: Both trials demonstrated that the time spent in hypoglycemia over a 24-hour period, as well as overnight, was markedly reduced by flash CGM without deterioration in glycated hemoglobin (A1C) levels. In IMPACT there was a 38% reduction in time in hypoglycemia with flash CGM versus SMBG, and in REPLACE there was a 43% reduction in time in hypoglycemia with flash CGM compared with SMBG. Moreover, patient satisfaction improved with flash CGM, usage adherence rates were high, and flash CGM was well tolerated. Conclusions: The findings from these trials suggest that improved care outcomes can be achieved when flash CGM is integrated into current established clinical care paradigms. Flash CGM provides important advantages over SMBG that are likely to be applicable to real-world care of indi Continue reading >>
Flash Glucose Monitoring
Flash glucose monitoring is sensor technology that enables you to test your glucose levels without pricking your finger. This technology is currently available in the Freestyle Libre system. The system has two parts. A small white disc (about the size of a twenty cent coin) is positioned on the back of the upper arm. This holds the sensor, which is worn just under the skin. And, a reader which when held over the sensor, gives a glucose reading. The flash glucose monitoring device is useful for detecting glucose level trends and tracking patterns. This device is suitable for people living with diabetes who require insulin to manage their condition. Each scan provides the last eight hours of glucose data and a trend arrow showing if glucose levels are going up, down or changing slowly. This data can be downloaded from the Freestyle Libre Software to give you and your Credentialled Healthcare Professional a deeper understanding of glucose patterns and variability Freestyle Libre is the only flash glucose monitoring device currently available on the Australian market. The FreeStyle Libre Flash Glucose Monitoring System has been approved by the Therapeutic Good Authority (TGA) for persons aged 4 and older who require insulin to manage their diabetes. For children (age 4 - 17), approval is limited to those whose diabetes management is supervised by a caregiver who is at least 18 years of age. Continue reading >>
Flash Glucose Monitoring
What It Does: Flash Glucose Monitoring* (FGM) is the newest method of glucose testing that is seen as a hybrid between meters and CGMs. The Abbott FreeStyle Libre is currently the only flash glucose monitoring product available, and it is currently only approved in Europe. In Flash Glucose Monitoring, patients have a sensor inserted on their upper arm and a separate touchscreen reader device. When the reader device is swiped close to the sensor, the sensor transmits both an instantaneous glucose level and eight-hour trend graph to the reader. This allows people to get individual blood sugar readings (like BGM) and trend information (like CGM). However, unlike CGM, FGM does not have hypo- or hyperglycemia alarms and will only provide a trend graph if it has been swiped in the past eight hours. The FreeStyle Libre system does not require fingerstick calibration, so users can dose insulin based on its readings (except for when hypoglycemic, when glucose levels are rapidly changing, or when symptoms don’t match the system’s readings). What Supplies Do I Need? To use the FreeStyle Libre, multiple parts are required: Touchscreen reader device – displays data and trend information Sensor patch – worn on the upper arm for 14 days Useful Links: Abbott Debuts Flash Glucose Monitoring System: A New Alternative to Fingersticks – An article on a new alternative to fingersticks and CGM’s.
