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.
