Dexcom STS (2006): The Birth of Dexcom's Continuous Glucose Monitoring
WE ASKED FOR: More insight into our glucose levels
WE GOT: A continuous glucose monitor
Prior to Dexcom’s presence in Canada, the company initiated a revolutionary wave in diabetes management with its first ever CGM system, the STS (which stands for Short Term Sensor). This 3-day monitoring system may not have been nearly as advanced as future iterations, but it laid the groundwork by enabling continuous tracking of glucose levels throughout the day and night. This innovation, although requiring a separate receiver for glucose readings, was an initial step towards the transformative future of CGM technology.
Even though the STS had a MARD* of 26%, indicating there was room for improvement in precision, it marked a significant beginning by providing a constant monitoring capability, which was a noteworthy advancement at the time.
*In simple terms, MARD stands for Mean Absolute Relative Difference, which is a measurement used to assess the accuracy of a continuous glucose monitoring system. It represents how closely the CGM readings align with blood glucose values measured by the YSI method, which is a laboratory reference standard for glucose measurement. A lower MARD value indicates higher accuracy, meaning that the CGM system provides glucose readings that are closer to the actual blood glucose levels.
Dexcom STS 7 (2008): The Seven System
WE ASKED FOR: A longer wear sensor
WE GOT: 7-day wear
The Dexcom Seven System, still unavailable in Canada, provided a significantly more extensive and detailed understanding of glucose trends with its 7-day monitoring period. This extended period between sensor changes wasn’t just convenient but also offered the Type 1 community a deeper and more nuanced insight into their glucose management.
The receiver of the Seven System was designed thoughtfully, incorporating convenience in viewing various glucose trends and real-time readings. With 30 days of data storage, it gave users a comprehensive view of their glucose history, hinting at future sophistication in diabetes management technology that would become available to Canadians in subsequent versions.
Dexcom Seven Plus (2009): Enhanced Accuracy and Convenience
WE ASKED FOR: A warning system for lows
WE GOT: Low alerts and alarms
Still not available in Canada, the Dexcom Seven PLUS retained the 7-day sensor wear, offering a full week of uninterrupted glucose monitoring, which was notably advantageous considering competitors offered between 3 to 5 days of wear. This system subtly addressed issues related to cost-effectiveness and user comfort while providing continuous glucose monitoring.
The SEVEN PLUS also brought to light a significant enhancement in safety features and user interface, introducing hypo-alerts, a Hypo-Safety-ALARM, and snooze functionality. These additions provided users with a reliable and robust alert system for potential hypoglycemic events, adding an essential layer of security in glucose management.
Dexcom G4 Platinum (2014): Extended Range, Vibrant Style, and Integrated Lifestyle Solutions
WE ASKED FOR: Better range & fewer signal losses; Some colour
WE GOT: 20-foot transmission range: Vibrant colour options
Finally, we welcomed Dexcom to Canada! The G4 PLATINUM blended the company’s remarkable technological advancements with a variety of aesthetic options for users and a large jump in accuracy, with a MARD of around 13%. The 20-foot transmission range between the sensor and the receiver provided unprecedented flexibility, allowing Canadians to manage their diabetes actively and with style, thanks to the vibrant colour options.
The G4 PLATINUM also introduced Canadians to more user-friendly experiences and personalized management, featuring customizable alerts and easy data sharing through Dexcom Studio. This was a demonstration of Dexcom’s commitment to supporting Canadian users with precise and lifestyle-integrated diabetes management solutions.
Beyond just technology and style, Dexcom’s association with Animas for the G4 showcased an initial commitment to the Canadian market, laying the groundwork for a deeper, direct involvement in the coming years.
Dexcom G5 Mobile (2017): Smartphone Compatibility, Real-Time Data Sharing and Peace of Mind
WE ASKED FOR: Glucose data straight to our phones; Easier insertion
WE GOT: The ability for a smartphone to be a receiver; A simple insertion device that hides the needle
2017 was a milestone year for both Dexcom and Canadians managing diabetes. With the launch of the G5 Mobile, Dexcom transitioned from its distributorship model with Animas to establishing its direct office and distribution channel in Canada. This move wasn’t just for efficient business operations; it signified Dexcom’s intensified commitment to Canadians. By ensuring direct touchpoints, Dexcom aimed to be more responsive to the local needs and nuances.
With more people using mobile phones daily and carrying them everywhere, the Dexcom G5 Mobile’s launch in Canada took advantage of this by changing how Canadians managed their diabetes, boasting a MARD of 9%. With accuracy taking the forefront, Canadians now had an even more reliable tool to manage their diabetes. By giving easy access to glucose data right on their phones, the G5 made it so people didn’t need an extra device. This meant fewer things to carry and the bonus of sharing glucose data with loved ones in real-time. This easy-to-use and discreet solution became a favorite in the Type 1 diabetes community.
Also, the G5 brought Canadians the Dexcom CLARITY platform. This cloud-based system showed detailed data and trends about their glucose levels. This helped people and their healthcare providers make better decisions and come up with diabetes management plans that fit their lives, mixing technology and care in the Canadian diabetes community.
Dexcom G6 (2019): Simplified Diabetes Management for Freedom to Thrive
WE ASKED FOR: No more calibrations; Better alerts & alarms; A more simple applicator
WE GOT: A Calibration-free system; Customizable, rate of change alerts
The Dexcom G6 represented a significant leap forward in the CGM experience for Canadians. One of its standout features was the advanced accuracy (with a MARD of 8.7%) that allowed for the dosing of insulin without the need for fingerstick calibrations, a testament to the system’s improved precision. Although real-time readings on smart devices were introduced with the G5, the G6’s enhancement in accuracy took glucose monitoring to a new level.
But what really set the G6 apart was its innovative auto-applicator. Unlike the manual process with the G5, the G6’s applicator was designed to hide the needle, making the insertion virtually painless. Its one-handed, automated insertion ensured consistency in application, which was a game-changer for many users. Moreover, the sensor could reliably read glucose levels even when acetaminophen was present, addressing a previously known concern with CGM systems. And with the added benefits of an extended 10-day sensor wear and suitability for children aged 2 and above, the G6 solidified its position as a groundbreaking and user-friendly tool in the diabetes management journey for Canadians.
The Future is Here with Dexcom G7 CGM
WE ASKED FOR: Less warm-up; Less waste; Smaller design
WE GOT: A 30-minute warm-up (which starts on insertion); New, smaller inserter; Totally redesigned and smaller sensor/transmitter combo
