A New, Wireless-enabled Blood Glucose Monitoring System That Links to a Smart Mobile Device: Accuracy and User...

Area of Science:

• Medical Devices
• Diabetes Technology
• Clinical Diagnostics

Background:

• The Contour®Next ONE blood glucose monitoring system (BGMS) is a novel device designed for seamless synchronization with the Contour™ Diabetes app.
• Accurate blood glucose monitoring is crucial for effective diabetes management.

Purpose of the Study:

• To evaluate the analytical and clinical accuracy of the Contour®Next ONE BGMS.
• To assess user feedback on the ease of use of the BGMS and its accompanying app.

Main Methods:

• Laboratory accuracy was assessed using fingertip capillary blood samples against ISO 15197:2013 Section 6.3 standards.
• Clinical accuracy was evaluated in subjects with and without diabetes according to ISO 15197:2013 Section 8 criteria, comparing self-tests, alternate site tests, and venipunctures to a reference.
• User feedback was gathered through a questionnaire regarding system usability.

Main Results:

• 100% of laboratory results met ISO 15197:2013 Section 6.3 accuracy criteria across three test strip lots.
• In clinical studies, over 97% of self-test results met ISO 15197:2013 Section 8 accuracy criteria, with many within ±10% of the reference value.
• The majority of participants found the Contour®Next ONE system easy to use.

Conclusions:

• The Contour®Next ONE BGMS demonstrates high accuracy, exceeding established ISO 15197:2013 criteria in both laboratory and clinical settings.
• The system's performance suggests it is a reliable tool for blood glucose monitoring in individuals with diabetes.
• User feedback supports the system's ease of use, indicating good patient acceptance.
