Conditions

Type2 Diabetes

Brief summary

This study allows Type 2 diabetics to receive feedback from a continuous glucose monitor (CGM) as part of an educational program designed to help them better manage their glucose levels. Subjects will also wear an activity tracker to monitor their activity and observe its effect on their glucose levels. The educational program will involve calls from coaches to check subjects' progress and answer questions.

Interventions

DEVICEContinuous Glucose Monitor (CGM)

Subjects will use a CGM to develop an understanding of how their behaviors influence their glucose levels.

Subjects will use the activity tracker, in combination with a continuous glucose monitor (CGM), to develop an understanding of how their activity levels affect their glucose levels.

BEHAVIORALCoaching

Coaches will help subjects understand the readings from the CGMs and how they are affected by diet choices, use of diabetes medications, etc. Coaches and subjects will have weekly conversations about CGM data and behaviors that affect CGM readings. Coaching will occur via telephone, text messaging, and automated text messaging.

Primary

Program Enrollment Rate (%)

(Number of patients who signed a consent form)/(Number of patients invited to enroll)

Time frame: up to three months

Population: 52 participants enrolled in the study. Hence, 52 participants analyzed. However, enrollment rate is the number of participants enrolled (52) divided by the number of candidates contacted (364). This explains why the Overall Number of Participants Analyzed is greater than the number Started in the Participant Flow.
