An observational study in Prediabetes, sponsored by University of South Florida. Recruiting at 2 sites in United States. Open to participants aged 18 Years to 70 Years. Per ClinicalTrials.gov, last updated 2026-08-10.
Sponsored by University of South Florida · Observational
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:
adults 18-70 years of age with prediabetes (HbA1c 5.7-6.4%)
Exclusion Criteria:
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
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.
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.

Time frame: Baseline to End of Week 4 (CGM wear period)
Time in Euglycemic Range Increase 10%
Change in the number of subjects increasing 10% or more in time in euglycemic range (54-120 mg/dL) at 4 weeks, compared within the intervention cohort

Summary of Diabetes Self-Care Activities Measure (SDSCA)
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.
Time frame: Baseline to End of Study (12 weeks)
Summary of Diabetes Self-Care Activities Measure (SDSCA)
Change in the Summary of Diabetes Self-Care Activities Measure at 4 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.
Time frame: Baseline to End of Week 4 (CGM wear period)
36-Item Short Form Health Survey (SF-36)
Change in the 36-Item Short Form Health Survey (SF-36) Measure at 12 weeks, compared within the intervention group. Produces 8 domain scores and is scored on a 0 to 100 scale. 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.
