Self-Monitoring of Blood Glucose

Effect of low-frequency blood glucose self-monitoring on glycosylated hemoglobin levels among older adults with type 2 diabetes mellitus

Background

Reducing the frequency of self-monitoring of blood sugar, due to needle phobia, pain, stress, and costs associated with the procedure, can improve patient compliance and quality of life, provided that adequate blood sugar control is maintained. This study aimed to evaluate the effect of low-frequency blood glucose self-monitoring (LFBGSM) on glycosylated hemoglobin (HbA1C) levels among older adults living with type 2 diabetes mellitus (T2DM), treated with or without insulin.

Materials and Methods

This randomized controlled trial with a parallel design was conducted on 121 older adults with T2DM in Sabzevar, Iran, between 2018 and 2020. Initially, subjects were stratified based on the type of treatment (with or without insulin) and then randomly assigned to intervention (LFBGSM) and control (no blood glucose self-monitoring [no-BGSM]) groups. HbA1C levels were measured at the beginning of the study and 3 months later for all study groups.

Results

The mean age of participants treated with and without insulin was 64.3 ± 9.60 and 64.7 ± 5.01 years, respectively. The ANCOVA test revealed a significant difference in the mean HbA1C levels among the four groups 3 months postintervention (P < 0.001). The HbA1C scores significantly decreased in the LFBGSM groups and increased in the no-BGSM groups at 3 months postintervention (insulin/LFBGSM, insulin/no-BGSM, noninsulin/LFBGSM, and noninsulin/no-BGSM: 7.74 ± 0.76, 8.34 ± 1.53, 7.70 ± 0.75, and 8.14 ± 1.11, respectively) compared to baseline (8.25 ± 0.67, 8.03 ± 0.64, 8.08 ± 0.69, and 7.83 ± 0.74, respectively). The least significant difference post hoc tests showed significant differences between specific groups, emphasizing subtle responses to interventions (P values ranging from 0.001 to 0.929).

Conclusion

Findings suggest a significant reduction in HbA1C scores within the LFBGSM groups, while a discernible increase is observed in the no-BGSM groups over the 3 months. These findings underscore the efficacy of the interventions and emphasize the crucial role of personalized approaches in optimizing glycemic control for individuals with diabetes.

Enhanced self-monitoring blood glucose in non-insulin-requiring Type 2 diabetes: A qualitative study in primary care

AIMS AND OBJECTIVES

To contribute to both theoretical and practical understanding of the role of self-monitoring blood glucose for self-management by describing the experience of people with non-insulin-requiring Type 2 diabetes in an enhanced structured self-monitoring blood glucose intervention.

BACKGROUND

The complex context of self-monitoring blood glucose in Type 2 diabetes requires a deeper understanding of the clients' illness experience with structured self-monitoring of blood glucose. Clients' numeracy skills contribute to their response to blood glucose readings. Nurses' use of motivational interviewing to increase clients' regulatory self-efficacy is important to the theoretical perspective of the study.

DESIGN

A qualitative descriptive study.

METHODS

A purposive sample of eleven adults recently (<2 years) diagnosed with non-insulin-requiring Type 2 diabetes who had experienced a structured self-monitoring blood glucose intervention participated in this study. Audio recordings of semi-structured interviews and photographs of logbooks were analysed for themes using constant comparison and member checking.

RESULTS

The illness experience states of Type 2 diabetes include 'Diagnosis,' 'Behavior change,' and 'Routine checking.' People check blood glucose to confirm their Type 2 diabetes diagnosis, to console their diabetes-related fears, to create personal explanations of health behaviour's impact on blood glucose, to activate behaviour change and to congratulate their diabetes self-management efforts.

CONCLUSIONS

These findings support the Transtheoretical model's stages of change and change processes. Blood glucose checking strengthens the relationships between theoretical concepts found in Diabetes Self-management Education-Support including the following: engagement, information sharing and behavioural support.

RELEVANCE TO CLINICAL PRACTICE

Tailoring diabetes care specifically to clients' stage of their illness experience with use of self-monitoring blood glucose contributes to engagement in self-management. Motivational interviewing and collaborative decision-making using blood glucose checking increase regulatory self-efficacy for people living with non-insulin-requiring Type 2 diabetes.
