Effect of Continuous Quality Improvement Based on the Diabetes Plate on Dietary Management in Young and Middle-Aged Patients with Type 2 Diabetes

Objective: To investigate the effects of continuous quality improvement (CQI) on dietary adherence, glycemic control, lipid profiles, and glycated hemoglobin (HbA1c) levels in young and middle-aged patients with type 2 diabetes mellitus (T2DM). Methods: A time-based quasi-experimental before-after study was conducted using a Plan-Do-Check-Act (PDCA)-based continuous quality improvement program. Patients admitted between January and June 2023 were assigned to the pre-intervention phase, while those admitted between July and December 2023 were assigned to the post-intervention phase. Within each phase, 60 eligible patients were randomly sampled from hospitalized patients. Outcomes related to dietary adherence, glycemic control, lipid profiles, and HbA1c levels were compared before and after the intervention. Results: Following the implementation of CQI, the proportion of patients with qualified dietary adherence and overall glycemic control performance significantly improved. In addition, serum lipid levels and HbA1c levels showed significant improvement after the intervention (all P Conclusion: The implementation of continuous quality improvement effectively enhanced self-management abilities related to nutritional behaviors among young and middle-aged patients with T2DM.
