SAT-530 - Enhancing Internal Medicine Residents' Knowledge and Confidence in Continuous Glucose Monitoring through Structured Educational Training

Introduction
Continuous glucose monitoring (CGM) is essential in diabetes management and requires collaboration between primary care physicians and endocrinologists. However, internal medicine residency programs often provide limited CGM education. Studies have found that insufficient clinician knowledge is a barrier to CGM prescribing in primary care. This quality improvement initiative aims to enhance CGM education for internal medicine residents through structured educational training.
Methods
A CGM educational series was promoted as an intervention during the 2024–2025 academic year in an internal medicine residency program. The series included an expert-led lecture, a resident-led session, and a hands-on CGM application workshop using demonstration devices provided by industry. Resident participation was voluntary. Anonymous, de-identified pre- and post-intervention surveys were used to assess CGM-related knowledge and self-perceived clinical confidence. To ensure confidentiality and enable paired analysis, residents generated random identification numbers to link responses anonymously. Knowledge was measured using an 11-question multiple-choice instrument developed by expert consensus. A five-point Likert scale was used to assess confidence in CGM application, patient education, and data interpretation.
Results
Fourteen internal medicine residents (n=14) completed matched pre- and post-intervention surveys. Linking each participant’s pre- and post-survey scores enabled measurement of individual improvement. Mean knowledge scores increased from 4.4 (median 4.5, SD 1.55) pre-intervention to 6.0 (median 6.0, SD 0.96) post-intervention. The mean increase was 1.57 points (p < 0.01). Score differences were approximately normally distributed, with no extreme outliers, supporting the use of a paired t-test. The analysis demonstrated a statistically significant increase (p < 0.01), indicating that post-test performance exceeded pre-test performance. Self-perceived clinical confidence improved across all domains. For example, the proportion of residents who reported feeling 'very' or 'extremely' comfortable with CGM sensor application increased by 50 percentage points, from 21.4% to 71.4%. Comfort with patient education increased by 42.6 percentage points, from 28.8% to 71.4%. Comfort with CGM data interpretation increased by 57.2 percentage points, from 21.4% to 78.6%. Reports of low confidence decreased by 63.9 percentage points, from 71% to 7.1%.
Conclusion
Structured CGM training improved residents’ knowledge and confidence in CGM. These findings support ongoing CGM education in residency curricula to better prepare future primary care physicians and foster a multidisciplinary approach to diabetes management.
