Diabetes self-management education after pre-selection of patients: design of a randomised controlled trial

COVID-19 Impact Predicts Diabetes Distress Among Individuals With Type 2 Diabetes

PURPOSE

The purpose of this study was to determine whether COVID-19 impact and Diabetes Self-Management Education and Support (DSMES) service attendance predicted diabetes distress among individuals with type 2 diabetes during the pandemic.

METHODS

Eighty-six adults with type 2 diabetes who either attended (n = 29) or did not previously attend (n = 57) DSMES services completed a cross-sectional survey. Participants' mean age was 57 ± 12.3 years, 50% were female, and 71.3% were diagnosed with diabetes >5 years. The Coronavirus Impact Scale was used to measure impact of the pandemic on daily life. The Diabetes Distress Scale was used to measure distress overall and within 4 subscales (emotional burden, interpersonal distress, physician-related distress, regimen distress). Separate multiple linear regressions were conducted for each outcome, controlling for age, sex, marital status, financial status, and time since diabetes diagnosis.

RESULTS

Higher COVID-19 impact predicted higher diabetes-related distress for all subscales and overall. Only the subscale for interpersonal distress was predicted by DSMES attendance, which decreased with DSMES attendance.

CONCLUSION

This study identifies a link between the effects of the COVID-19 pandemic and diabetes distress. The findings highlight the negative impact of the pandemic on diabetes distress and the importance of DSMES services for diabetes-related distress. Interventions are needed to reduce psychological distress among this population during public health crises.

Effectiveness of the Beyond Good Intentions Program on Improving Dietary Quality Among People With Type 2 Diabetes Mellitus: A Randomized Controlled Trial

Background and Aims: An appropriate diet is an essential component of the management of Type 2 Diabetes Mellitus (T2DM). However, for many people with T2DM, self-management is difficult. Therefore, the Beyond Good Intentions (BGI) education program was developed based on self-regulation and proactive coping theories to enhance people's capabilities for self-management. The aim of this study was to determine the effectiveness of the BGI program on improving dietary quality among a preselected group of people with T2DM after two-and-a-half years follow-up.

Methods: In this randomized controlled trial, 108 people with T2DM were randomized (1:1) to the intervention (n = 56) (BGI-program) or control group (n = 52) (care as usual). Linear regression analyses were used to determine the effect of the BGI program on change in dietary quality between baseline and two-and-a-half years follow-up. In addition, potential effect modification by having a nutritional goal at baseline was evaluated. Multiple imputation (n = 15 imputations) was performed to account for potential bias due to missing data.

Results: According to intention-to-treat analysis, participants in the intervention group showed greater improvements in dietary quality score than participants in the control group (β = 0.71; 95%CI: 0.09; 1.33) after follow-up. Having a nutritional goal at baseline had a moderating effect on the effectiveness of the BGI program on dietary quality (p-interaction = 0.01), and stratified results showed that the favorable effect of the intervention on dietary quality was stronger for participants without a nutritional goal at baseline (no nutritional goal: β = 1.46; 95%CI: 0.65; 2.27 vs. nutritional goal: β = −0.24; 95%CI: −1.17; 0.69).

Conclusions: The BGI program was significantly effective in improving dietary quality among preselected people with T2DM compared to care as usual. This effect was stronger among participants without a nutritional goal at baseline. A possible explanation for this finding is that persons with a nutritional goal at baseline already started improving their dietary intake before the start of the BGI program. Future studies are needed to elucidate the moderating role of goalsetting on the effectiveness of the BGI program.

Theory-based diabetes self-management education with pre-selection of participants: a randomized controlled trial with 2.5 years' follow-up (ELDES Study)

AIMS

To evaluate the (cost-)effectiveness of Beyond Good Intentions (BGI), a 12-week group-based, nurse-led self-management programme, in terms of cardiovascular risk factors, self-management and quality of life, after 2.5 years of follow-up in pre-selected individuals with known Type 2 diabetes of up to 5 years' duration.

METHODS

A parallel randomized controlled trial comparing BGI with usual care, based on a self-management screening questionnaire, was conducted in 43 general practices after pre-selection of participants. After 2.5 years of follow-up, the between-group changes in the abovementioned variables were assessed using analysis of covariance.

RESULTS

A total of 108 participants (BGI group, n =56; control group, n =52) were included. Changes over time in BMI (-0.4 vs -0.5 kg/m² ) were similar in the two groups. Median HbA_1c [BGI group 47 mmol/mol (6.5%); control group: 49 mmol/mol (6.6%)] and mean systolic blood pressure (BGI group: 132±13 mmHg; control group: 133±14 mmHg) were well controlled at baseline and no intervention effect was found. LDL cholesterol levels decreased from 2.4 to 2.2 mmol/l in the control group and remained stable at 2.6 mmol/l in the intervention group (P=0.032). No intervention effect was found for self-management or quality of life.

CONCLUSION

In contrast to the first BGI study, we did not observe significant effects of the BGI intervention, despite pre-selection of individuals. In diabetes populations with target levels for HbA_1c , systolic blood pressure and LDL cholesterol, no further beneficial effects can be expected from self-management programmes with regard to biomedical factors and quality of life.
