Pharmacist-Led Continuous Glucose Monitoring for Prediabetes

The goal of this observational study is to determine if a pharmacist-led program involving continuous glucose monitoring (CGM) improves glucose control and health behavior in people with prediabetes. The main questions it aims to answer are:

1. Determine impact of pharmacist-led CGM on glycemic control in people with prediabetes. Researchers will compare change in hemoglobin A1c at 12 weeks with pharmacist-led CGM versus a historical cohort of subjects with prediabetes receiving no CGM. The investigators will also assess change in CGM-derived glycemic metrics from baseline to end of the CGM wear period in the intervention group. 2. Evaluate impact of pharmacist-led CGM on health behavior change in people with prediabetes in the intervention group. Participants will be asked to complete the Summary of Diabetes Self-Care Activities Measure (SDSCA) and 36-Item Short Form Health Survey (SF-36) at baseline, at the end of week 4, and at the end of the study so that researchers can measure the effects in the intervention group on health behavior change.

Treatment and study plan

Dexcom Stelo CGM

Device

Subjects included in the intervention group will be recruited from the USF Health Department of Family Medicine. Each subject will be enrolled for 12 weeks. The CGM sensors are worn on the upper arm and changed every 15 days.

Primary outcomes

  1. Change in hemoglobin A1c

    Time frame: Baseline to End of Study (12 weeks)

    Between-group difference in change in hemoglobin A1c at 12 weeks, %, compared between intervention and historical cohort

Secondary outcomes

  1. Time in Range

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in the time in range (70-140 mg/dL) at 4 weeks, %, compared within the intervention cohort

  2. Time in Euglycemic Range

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in the time in euglycemic range (54-120 mg/dL) at 4 weeks, %, compared within the intervention cohort

  3. Mean Sensor Glucose

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in mean sensor glucose concentration at 4 weeks, mg/dL, compared within the intervention cohort

  4. Time Below Range

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in time below range (< 70 mg/dL) at 4 weeks, %, compared within the intervention cohort

  5. Time Above Range

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in time above range (141-250 mg/dL and > 250 mg/dL) at 4 weeks, %, compared within the intervention cohort

  6. Glycemic Variability

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in glycemic variability (standard deviation, and Coefficient of variance) at 4 weeks, compared within the intervention cohort

  7. Time in Range Increase 5%

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in the number of subjects increasing 5% or more in time in range (70-140 mg/dL) at 4 weeks, compared within the intervention cohort

    Time frame: Baseline to End of Week 4 (CGM wear period)

    Change in the number of subjects increasing 10% or more in time in range (70-140 mg/dL) at 4 weeks, compared within the intervention cohort

    Time frame: Baseline to End of Study (12 weeks)

    Change in the Summary of Diabetes Self-Care Activities Measure at 12 weeks, compared within the intervention group. Scored on an 8-point likert scale (0-7). Higher scores indicate better compliance with diabetes self-care, whereas a lower score indicate poor self-care performance.

For the standard domain scores, higher scores indicate a more favorable health state. A score of 100 reflects the best health status on that domain, and 0 the worst.
