Continuous Glucose Monitoring With Immediate or Delayed Counseling Feedback
- Conditions
- Type2 Diabetes
- Interventions
- Behavioral: feedback counseling
- Registration Number
- NCT03792399
- Lead Sponsor
- National Cheng-Kung University Hospital
- Brief Summary
This study is designed to explore the effect of feedback counseling using professional continuous glucose monitoring on glycemic control, self-efficacy, and self-management behaviors among middle aged and older adults with poor controlled type 2 diabetes mellitus. This study also explores the difference on timing of feedback after continuous glucose monitoring exam.
- Detailed Description
After scheduled routine professional continuous glucose monitoring (CGM) exam, participants in both the intervention and control group receive ordinary education and regimen adjustment as indicated based on CGM results. For participants in the intervention group, they will also receive CGM counseling immediately on the day of CGM sensor removal. For participants in the control group, they will receive CGM counseling on the day of routine 3 months outpatient visit.
Qualitative data are collected through in-depth interview: User expectation, acceptability and satisfaction of CGM are also explored during in-depth interview with a semi-structured questionnaire.
Quantitative data were collected through validated questionnaires, including evaluation of depression by a short form of the Center for Epidemiologic Studies Depression Scale Revised (CES-D-R), emotional stress by Problem Areas in Diabetes Scale (PAID), self efficacy by Stanford Self-Efficacy for Diabetes (SES), at pretest and 3 months after CGM counseling.
Anthropometric Measurements. Body height, body weight, body mass index, and blood pressure were recorded at pre-test and post-test interview.
Blood Tests. Routine biochemistry, fasting plasma glucose, hemoglobin A1c (HbA1c) are collected within 2 weeks of pretest and posttest day.

Group Intervention Description Delayed feedback counseling feedback counseling Professional CGM calibrate blood glucose via a glucsoe-oxidase-impregnated membrane during a 5 day period. The patient wearing professional CGM is randomized to delayed feedback (standard care, i.e., CGM graphs interpretation at scheduled 3 months outpatient visit). Immediate feedback counseling feedback counseling Professional CGM calibrate blood glucose via a glucsoe-oxidase-impregnated membrane during a 5 day period. The patient wearing professional CGM is randomized to immediate feedback after data downloaded into computer.
- Primary Outcome Measures
Name Time Method Change of HbA1c Baseline and 3 months after CGM counseling Change of HbA1c in 3 months after CGM counseling.
Change of score for self efficacy Baseline and 3 months after CGM counseling Change of Stanford Self-Efficacy for Diabetes Scale (SES) in 3 months after CGM counseling. The score for each item ranged from 1-10. The score of the scale is the mean of the eight items. Higher number indicated higher self-efficacy.
- Secondary Outcome Measures
Name Time Method Change in exercise amount, time spent in moderate activity Baseline and 3 months after CGM counseling Exercise amount recorded by acelerometers, built in sports bracelet (Fitbit Charge HRTM Wireless Heart Rate + Activity Wristband). Time spent in moderate activity per day in 3 months after CGM counseling feedback is compared with baseline.
Change of score for diabetes associated stress Baseline and 3 months after CGM counseling Change of score for Problem Areas in Diabetes Scale (PAID) in 3 months after CGM counseling. PAID is a 20-item self-reported questionnaire with scale 0-4 for each question, generating a total score of 0-100. A score of ≥ 40 is defined as emotional burnout.
Change of score for depression Baseline and 3 months after CGM counseling Change of score for Center for Epidemiologic Studies Depression Scale Revised (CESD-R) in 3 months after CGM counseling. With 10-ietm CESD-R scale scoring 10 or more defined as having depression (range 0 to 30).
Change in diet composition Baseline and 3 months after CGM counseling Change of carbohydrate amounts, fruits amount in 3 months after CGM counseling.
Change in exercise amount, time spent in light activity Baseline and 3 months after CGM counseling Exercise amount recorded by acelerometers, built in sports bracelet (Fitbit Charge HRTM Wireless Heart Rate + Activity Wristband). Time spent in light activity per day in 3 months after CGM counseling feedback is compared with baseline.
Change in exercise amount, time spent in intense activity Baseline and 3 months after CGM counseling Exercise amount recorded by acelerometers, built in sports bracelet (Fitbit Charge HRTM Wireless Heart Rate + Activity Wristband). Time spent in intense activity per day in 3 months after CGM counseling feedback is compared with baseline.
Change in exercise amount (time spent in sedentary behavior) Baseline and 3 months after CGM counseling Exercise amount recorded by acelerometers, built in sports bracelet (Fitbit Charge HRTM Wireless Heart Rate + Activity Wristband). Time spent in sedentary behavior in 3 months after CGM counseling feedback is compared with baseline.
