Background: Screening for type 1 diabetes (T1D) can be challenging, causing diagnostic delay and potentially serious health consequences. Continuing education (CE) in T1D is lagging but could help improve clinician knowledge of and engagement in T1D screening behaviors.

Materials and methods: This retrospective, case-control study assessed pre-/post-changes in clinician knowledge of T1D screening and management (N=4817) following exposure to an interactive, multicomponent CE program (DETECT T1D) from May 2024 to January 2025. Using medical claims, it evaluated pre/post practice change by comparing learners and matched non-learner controls (N=9361) on T1D screening behaviors during the 12 months pre-education vs all available month’s post-education through May 2025.x

Results: Post-education, learners demonstrated multiple knowledge and competence gains, including understanding the T1D presentation in adults versus children and identifying appropriate autoantibody screening strategies. Learners achieved a 54% increase in screenings (i.e., 668 more new screenings) following DETECT T1D education vs non-learners (1913 new screenings for learner’s vs 1245 new screenings for non-learners). Primary care, pediatric, and advanced practice provider learners in particular achieved a 116 % gain in screenings vs non-learners (715 new screenings vs 332 new screenings). Learners across all specialties and in all geographic regions demonstrated gains in new screenings vs non-learners.

Conclusion: Interactive, immersive, multicomponent CE may be a feasible and effective pathway to improving clinician detection of T1D. Exposure to this type of learning could have positive downstream effects for patients in terms of more timely diagnosis and earlier intervention, including with disease-modifying therapies that can delay T1D clinical progression.
