Objective: To assess the effectiveness of a glucose pattern management program on glycemic control and self-management behaviors in patients using basal insulin. Methods: This is a single-group repeated-measures design. Participants were 153 inpatients using basal insulin. The “5-step approach” was used to help know their target blood glucose; gather the data on BG levels, food intake, physical activity levels, medication doses, and stressors; look for patterns; assess possible relationships between BG values and behavior; and take actions. Outcomes were assessed at baseline and 3 months. Results: Thirty participants dropped out. About 88% of them reached the FPG control target (FPG ≤7.0 mmol/L), HbA1C levels significantly reduced in 3 months (P<0.001). Almost 80% of the patients reached the behavior goal, the problem-solving skills in hyperglycemia and hypoglycemia had been improved. Conclusion: Blood glucose pattern management can facilitate behavior change, improve problem-solving skills in hyperglycemia and hypoglycemia, and may have some positive effects on glycemic control in patients using basal insulin, further study is needed.
