Impact on Diabetes Self-Management and Glycemic Control of a New Color-Based SMBG Meter

Abstract

Background: Self-monitoring of blood glucose (SMBG) is a key pillar of personal diabetes management. The objective of this observational study was to analyze diabetes self-management (DSM) and glycemic outcomes before and during system implementation in real-life settings of a blood glucose meter system with a color-coded display of glucose levels, which helps identify out-of-range levels.

Methods: A total of 193 insulin-treated diabetes patients (11% T1DM; 55% male, age 60 ± 4 years, mean diabetes duration 14 ± 9 years, HbA1c 8.68 ± 1.2%) were enrolled into the study. Both the Diabetes Self-Management Questionnaire (DSMQ) and glycemic control were analyzed at baseline and 3 and 6 months after study initiation.

Results: DSMQ general perception improved significantly by the end of the study period ("Sum Scale," P < .05). Moreover, after 6 months patient's attitudes on self-care (Q16, P = .0046) and nutrition ("Dietary Control," P = .004) showed significant improvements. Use of the blood glucose meter resulted in improved glycemic control, as shown by mean HbA1c levels, which decreased from 8.68 ± 1.2% at baseline to 8.13 ± 1.02% after 3 months ( P < .0001) and to 7.9 ± 1.1% at 6 months ( P < .0001). Both patients and diabetes educators agreed in the advantages of the color-coded indicator and on its helpfulness in assisting patients on their diabetes management, as drawn from the results of the self-reported satisfaction questionnaire.

Conclusion: This real-world study demonstrates that SMBG implemented via this new blood glucose meter not only leads to an improvement in metabolic control, but also is associated with a significant improvement in diabetes management.
