Study summary

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.

Groups and cohorts

  • CGM Cohort (Intervention)

    Subjects meeting inclusion criteria will include adults 18-70 years of age with prediabetes (HbA1c 5.7-6.4%) obtained within the six months preceding enrollment. Subjects must have a compatible smartphone with the Dexcom CGM sensor system. Subjects must not have worn a CGM in the last 6 months to be eligible.

    Device: Dexcom Stelo CGM

  • No CGM Cohort (Retrospective Cohort)

    A retrospective chart review will be performed on patients seen at the USF Health Department of Family Medicine between 1/1/2025-03/20/2026. Subjects in this group will include adults 18-70 years of age with prediabetes (HbA1c 5.7-6.4%). Subjects in this cohort will have not received CGM.

Interventions

  • DeviceDexcom Stelo CGM

    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.

What researchers measure

Primary outcomes

  1. Change in hemoglobin A1c

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

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

Secondary outcomes

  1. Time in Range

    Change in the 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)

  2. Time in Euglycemic Range

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

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

  3. Mean Sensor Glucose

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

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

  4. Time Below Range

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

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

  5. Time Above Range

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

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