DIATAST - The Diabetes Patient Takes Responsibility

Short summary

The aim of the study is to test a new model of organizing the diabetes outpatient clinic for Type 1 diabetes patients. The new model aims at a higher degree of self-planning in the patients´ use of the outpatient clinic based on patients' needs. Patients are randomized to follow the normal scheduled visit procedure in the outpatient clinic or to have open access to the clinic within guaranteed time intervals.

Primary outcome is patient reported outcome (PRO) measures of patient satisfaction.

Secondary outcomes are clinical diabetes status (clinical variables), health economic evaluations of resources used in the outpatient clinic and by patients, and PRO measures of patient characteristics/personal preferences.

A secure internet website ("Diabetes-online") will be used by all patients to follow their own diabetic test results. In addition the website is used by the intervention group to communicate about booking of visits to the clinic.   


The organization of the life-long control of Type 1 diabetes by pre-planned visits is challenged in this study. The aim is to give capable patients the opportunity to have a higher degree of influence on their disease management and furthermore to allocate clinical resources to those patients that require a more structured and assisted disease management.
