We read with interest the article by Feng et al [
This trial aimed to assess the effectiveness of an eHealth family-based health education intervention for patients with T2DM to improve their glucose control, risk perception, and self-care behaviors.
After 1 year of intervention, patients in the intervention arm showed significantly lower hemoglobin A1c (HbA1c) values and improved several diabetes control–related skills (eg, general diet, special diet, blood sugar testing, foot care, risk knowledge, and personal control).
The authors concluded that the eHealth family-based intervention improved glucose control and self-care activities among patients with T2DM by aiding the implementation of interventions to enhance T2DM risk perceptions among family members. The intervention is generalizable for patients with T2DM using health management systems in community health centers. We applaud the authors in the preparation and execution of the study but have several questions that we feel would benefit the article’s readership.
In our observational study focused on metabolic control in patients with type 1 and type 2 diabetes treated with insulin in the Czech Republic and the Slovak Republic, we found a high clinical inertia resulting in a minimal and clinically insignificant difference in the mean HbA1c within 3 years. Thus, we believe any new intervention targeting a long-term stabilized balance between the health carers’ therapeutic approach and the corresponding patient response is essential and can lead to substantial positive results [
Based on the 7-point scale, the differences in the individual skills observed are not very large. From the authors’ perspective, which intervention had the most significant effect on changes in HbA1c?
Patients in the intervention group met with their physicians every 3 months. Is information available on the frequency of doctor visits in the control group?
The improvements in HbA1c values in the intervention arm are substantial. They even correspond to possible major changes in treatment (eg, initiation of insulin therapy) [
It is also known that patients with higher HbA1c levels benefit more from changes in therapy [
We respectfully suggest considering these remarks, especially if a study continuation is planned.
