Objective To evaluate the effectiveness of a "Zheli Nursing" platform-delivered Traditional Chinese Medicine (TCM) preventive healthcare program on TCM syndrome scores and glucose metabolism in community-dwelling type 2 diabetes patients. Methods A total of 140 community-dwelling patients with type 2 diabetes were randomized to a control group (n=70),receiving routine diabetes management, or an observation group (n=70), receiving TCM preventive healthcare via "Zheli Nursing" platform for 6 months. Blood glucose, TCM syndrome score, diabetes knowledge, diabetes self-management behavior, nerve conduction parameters and clinical efficacy were compared at baseline and post-intervention between the two groups. Results Compared to the control group, the observation group demonstrated significantly lower fasting blood glucose and glycosylated hemoglobin (HbA1c) post-intervention, reduced TCM syndrome scores at week 12 and post-intervention (showing significant group, time, and group×time interaction effects), and higher diabetes knowledge, self-management behavior, clinical efficacy (94.29%), and improved nerve conduction parameters post-intervention (all P<0.05). Conclusion The "Zheli Nursing" platform-delivered TCM preventive healthcare effectively regulates glucose levels, alleviates TCM syndromes, enhances diabetes knowledge and self-management ability, and improves neurological function in community-dwelling diabetes patients.
