Effect of Narrative Education on Glycemic Control in Adults With Type 2 Diabetes in Primary Care

Type 2 diabetes is common in primary care, and daily self-care behaviors are essential for achieving blood sugar targets. This randomized, two-arm clinical trial will evaluate whether a structured narrative education program added to usual diabetes care improves glycemic control compared with usual care alone in adults with type 2 diabetes. Eligible participants (age ≥18 years) with suboptimal glycemic control (HbA1c ≥7.0% in the last 3 months) will be randomized 1:1 to either standard care or standard care plus narrative education. The narrative education program will be delivered by a family physician over 3 months and includes two individual face-to-face sessions (approximately 20-30 minutes) at Day 0 and Day 15 and four brief telephone reinforcement calls (approximately 3-5 minutes) on Days 30, 45, 60, and 75. The primary outcome is the absolute change in HbA1c from baseline (Day 0) to Day 90. Secondary outcomes include changes in diabetes self-care activities (SDSCA-TR), diabetes-related distress (PAID-5-TR), and body mass index (BMI) from Day 0 to Day 90.
