Interim analysis of primary outcome (HbA1c at 6 months) revealed no numerical differences after 80 included participants. Further inclusion of participants to reach prespecified N to evaluate primary outcome deemed futile. 138 participants included.

The purpose of this study is to test the effect of using a digital diabetes self management education and support system compared with standard care for patients with type 2 diabetes in primary health care.

After being informed verbally and in text participants will sign a consent to participate. The participant will then be randomized to either use a digital diabetes self management education and support system for 10 weeks together with a diabetes nurse, or to continue with the regular care. The effects will be evaluated after 6, 12 and 36 months from randomization with emphasis on cardiovascular risk factors, life-style, diabetes knowledge and health economics.

Inclusion Criteria:

• Type 2 diabetes mellitus diagnosed according to WHO criteria < 5 years from randomization:
• Fasting plasma glucose > 7 mmol/L at two timepoints. OR
• HbA1c ≥ 48 mmol/mol twice or in combination with fasting plasma glucose > 7 mmo/L once. OR
• Non-fasting plasma glucose ≥ 11.1 mmol/L at one timepoint in combination with symptoms of hyperglycemia.
• Access to a digital ID-card to access the digital system
• Access to a computer, tablet or smart phone
• Sufficient knowledge of written and spoken Swedish to understand the information given in the digital system.

Exclusion Criteria:

• Treatment with Insulin
• Other co-morbidities limiting the use of the digital system according to the diabetes nurse judgement. E.g. dementia or severe psychiatric disease.
• Other forms of diabetes mellitus than type 2 diabetes.

Individual participant data will be available upon request to the principal investigator (Andreas Stomby) if it is in accordance with Swedish and international law. Thus, all requests will be judged before IPD is eventually shared.

Data will be available after the research group has conducted the planned analyses. Preliminary in year 2027.
