Health care effects and medical benefits of a smartphone-based diabetes self-management application: study protocol for a randomized controlled trial.

BACKGROUND: Diabetes self-management is a mainstay of diabetes care, but the implementation of self-management regimens into daily life is complex and often results in discouragement and distress. Modern approaches such as smartphone-based self-management applications are therefore needed to support people with diabetes. Since reimbursability would increase the availability of such digital applications to people with diabetes, we designed a study that meets all scientific and methodological requirements set by the German Digital Healthcare Act to allow reimbursement for a specific application (mySugr PRO). Here, we report the protocol of this study that aims at evaluating the efficacy of the digital self-management application with regard to patient-reported outcomes and medical benefits. METHODS/DESIGN: This multicenter, open-label, randomized, parallel-group, controlled trial will evaluate the health care effects and medical benefits of mySugr PRO. A total of 466 people with diabetes will be randomly allocated (2:1 randomization) to the interventional group (n = 311) that will use the digital self-management application during the 12-week study period or the control group (n = 155; no usage of the application). Baseline and follow-up examinations will assess diabetes distress as the primary endpoint as well as empowerment, HbA1c, blood glucose data, self-management, general well-being, and treatment satisfaction as secondary endpoints. Statistical analyses will use an intention-to-treat procedure (using multiple imputation for missing values) as well as a per-protocol approach for sensitivity analysis. DISCUSSION: To the best of our knowledge, this study will be one of the largest diabetes-specific evaluations of a digital health application supporting people with diabetes in their diabetes self-management that follow the requirements of the German Digital Healthcare Act.

Trends in diabetes self-management education: where are we coming from and where are we going? A narrative review.

AIMS: To summarize the history, development and efficacy of diabetes self-management education on glycaemic control and mental health in adults and children or adolescents with type 1 diabetes and people with type 2 diabetes. A further aim was to review the status of implementation of diabetes self-management education into routine care and outline current gaps in implementation and research. METHODS: We searched PubMed and Google scholar for German- and English-language articles regarding diabetes self-management education, glycaemic control and mental health, and restricted this search to meta-analyses. RESULTS: Diabetes education has evolved from a compliance- and knowledge-oriented approach to an empowerment- and self-management-oriented approach. Diabetes self-management education seems to have a greater impact on glycaemic outcomes than on mental health outcomes, but the latter are rarely assessed. Technological development and digitalization can provide chances and challenges for diabetes self-management education. Digital solutions show promising results and great potential for improving the efficacy of diabetes self-management education further and providing ongoing support. The implementation of diabetes self-management education into routine clinical care frequently remains a challenge. CONCLUSION: Diabetes self-management education has been acknowledged as an essential part of diabetes therapy; however, current gaps regarding the efficacy of diabetes self-management education on mental health, and the need for education on the use of diabetes technology, are future avenues for research.

The effect of an education programme (MEDIAS 2 BSC) of non-intensive insulin treatment regimens for people with Type 2 diabetes: a randomized, multi-centre trial.

AIMS: A self-management oriented education programme (MEDIAS 2 BSC) for people with Type 2 diabetes who are on a non-intensive insulin treatment regimen was developed. In a randomized, multi-centre trial, the effect of MEDIAS 2 BSC was compared with an established education programme that acted as a control group. METHODS: The primary outcome was the impact of MEDIAS 2 BSC on glycaemic control. Secondary outcomes included the incidence of severe hypoglycaemia, hypoglycaemia unawareness, diabetes-related distress, diabetes knowledge, quality of life and self-care behaviour. RESULTS: In total, 182 participants were randomized to the control group or MEDIAS 2 BSC [median age 64.0 (interquartile range 58.0-68.5) vs. 63.5 (57.0-70.0) years; HbA1c 62.8 ± 12.7 mmol/mol vs. 63.7 ± 14.0 mmol/mol; 7.9% ± 1.2% vs. 8.0% ± 1.3%]. After a 6-month follow-up, there was a mean decrease in HbA1c of 3.5 mmol/mol (0.32%) in the control group and 6.7 mmol/mol (0.61%) in MEDIAS 2 BSC. After adjusting for baseline differences and study centre, the mean difference between the groups was -3.3 mmol/mol [95% confidence interval (CI) -0.54 to -5.90 mmol/mol] [-0.30% (95% CI -0.05 to -0.54)] in favour of MEDIAS 2 BSC (P = 0.018). There were no increases in severe hypoglycaemia or hypoglycaemia unawareness. The education programmes had no significant effects on psychosocial outcome variables. CONCLUSION: MEDIAS 2 BSC was more effective in lowering HbA1c than the control condition. MEDIAS 2 BSC is a safe educational tool that improves glycaemic control without increasing the risk for hypoglycaemia. (Clinical Trials Registry No; NCT 02748239).

Limitations to the use of a sensitive assay for serum thyrotropin in the assessment of thyroid status.

In the majority of clinical settings, a suppressed serum thyrotropin (s-TSH) level determined by the new sensitive assays is diagnostic of thyrotoxicosis. This has led to its proposed use as a screen for thyroid disease. However, s-TSH may be suppressed in conditions other than thyrotoxicosis. We retrospectively reviewed s-TSH measurements made in a large heterogeneous population to determine in which settings a suppressed value could potentially lead to misdiagnosis. We found that a suppressed s-TSH level was useful in making the diagnosis of autonomous thyroid function and in the assessment of thyroid hormone replacement therapy in patients with primary, but not central, hypothyroidism. Hyperthyroidism caused by either intrinsic thyroid disease or thyroid hormone administration accounted for 83% (111/134) of suppressed values; however, central hypothyroidism, nonthyroidal illness, acute psychiatric illness, or the administration of medication was responsible for this finding in 17% (23/134). While a suppressed s-TSH level is generally excellent in the diagnosis of pituitary suppression by thyroid hormone, in specific clinical settings, a suppressed s-TSH level may be seen in the absence of thyroid hormone excess. The limitations of its use as a first-line screen in those conditions must be recognized.
