CareLink Connect - Technical Evaluation Study

Completed

• Conditions: Diabetes Mellitus

• Registration Number: NCT01989975
• Lead Sponsor: Medtronic Diabetes

Brief Summary

The purpose of this study is to evaluate the performance, patient satisfaction and safety of connectivity gateway device CareLink Connect, transferring CGM (Continuous Glucose Monitoring) data from a VEO insulin pump to CareLink online (every 5th minute) and thereby making it available for patients or Care Partners individual web connected devices such as smartphones, tablets and PCs.

   2. Recharge the transmitter.
   3. Read sensor data in real-time on the insulin pump screen.

4. Subject is willing to, or has a Care Partner who can, perform at least the minimum required (2 per day) Blood Glucose readings to maintain CGM Sensor calibration.

5. Subject, if under the age of 18, has a Care Partner who is willing to participate to the study, attend the study visit with the subject, and complete user's feedback questionnaires and Care Partner diary. Care Partners are optional for patients of 18 years of age or older.

6. Subject and/or Care Partner have access to a computer with Internet access.

7. Subject and/or Care Partner have access to an Internet connected device.

8. Subject, or their legal guardian, is willing to allow a Care Partner to receive and view information transmitted by their Paradigm® Veo™ Medtronic insulin pump to a Mobile phone/Smartphone/tablet/PC via the CareLink Connect/CareLink Personal System.

9. Subject is willing to keep CareLink Connect device in the same room as themselves or regularly carry the study device with them and maintain its operational status (at approximately 16h per 24h).

10. Subject is willing to keep a short diary during the device use reporting time periods away(for more than one hour) from the CareLink Connect device.

11. Subject is in good general health as judged by the PI.

Exclusion Criteria

Study & Design

• Study Type: OBSERVATIONAL
• Study Design: Not specified

Primary Outcome Measures

Name	Time	Method
CareLink Connect Activity: % of the Time Per Day When Cellular Connection Was Established	Outcome measured after 15 days of use of the CareLink Connect Device	The overall system connectivity between the pump, the CareLink Connect device, and the CareLink server will be measured. CareLink Connect activity will be measured by: * Date and time of CareLink Connect transmissions; * Transmission type and data sent in CareLink Connect transmissions (includes RF messages and history uploads)
Subject Experience After Using the Carelink Connect Device	Outcome measured after 15 days of use of the CareLink Connect Device	Subject experience after using the Carelink Connect device was evaluated with questionnaires. Subjects were asked the question: I felt that I had good control over my diabetes. Likert Scale of 1-7 was used in the study to evaluate the question (1 being the the worse, 4 being neutral and 7 being the best).

Secondary Outcome Measures

Name	Time	Method
Number of Participants With Serious Adverse Events	Outcome measured after 15 days of use of the CareLink Connect Device	Descriptive summary of number and type of serious adverse events (SAE)
Number of Participants With Investigational Device Deficiencies	Outcome measured after 15 days of use of the CareLink Connect Device	Subjects were instructed to report any inadequacies of a medical device including: * Lack of connection between the CareLink Connect device and the Veo pump (Connectivity issues); * Device Battery issue; * Device information display issue
