Serum value of fasting C-peptide (FC-P), fasting insulin (FIns), and glycated hemoglobin (HbA1c) after dynamic blood glucose monitoring-guided personalised nutrition and insulin pump therapy for type II diabetes mellitus.

BACKGROUND

Type 2 diabetes mellitus (T2DM) is a chronic metabolic disorder characterised by impaired glucose metabolism, which necessitates comprehensive management of blood glucose (BG), blood pressure, and lipid profiles. This study aimed to evaluate the clinical effects of individualised nutrition and insulin pump therapy, guided by continuous glucose monitoring (CGM) and the Quality Circle Control (QCC) nursing model, on various biomarkers in T2DM patients, including fasting C-peptide (FC-P), fasting plasma glucose (FPG), 2-hour postprandial glucose (2hPG), fasting insulin (FIns), and glycated haemoglobin (HbA1c).

METHODS

Eighty T2DM patients treated at our hospital were enrolled in the study between January 2023 and January 2024. Patients were assigned to either the experimental group (EG), which received individualised nutrition and insulin pump therapy supported by CGM and the QCC nursing model, or the regular group (RG), which received standard care. Differences in BG control, insulin usage, CGM system performance (including downtime and anomaly rates), and patient satisfaction were compared between the two groups.

RESULTS

The EG demonstrated significant improvements in FC-P, FPG, 2hPG, FIns, and HbA1c levels compared to the RG (P<0.05). Specifically, the EG showed more rapid achievement of BG targets, reduced glucose variability, lower insulin usage, and decreased CGM system anomalies.

CONCLUSIONS

The QCC nursing model, when integrated with individualised nutrition and insulin pump therapy guided by CGM, significantly enhances blood glucose control, optimises insulin therapy, and improves patient outcomes, including dietary habits, quality of life, and reduction in hypoglycemic events. This model shows promise as an effective strategy for managing T2DM and warrants further adoption in clinical practice.
