Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

The purpose of this randomized, prospective trial is to determine wether (a) a once weekly glucose profile (self monitoring) or (b) a three-monthly report of the actual glycated haemoglobin are effective interventions to improve HbA1c after one year in typ 2-diabetic patients on conventional insulin treatment.

Detailed Description

Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.

The design is an open, prospective, randomised, multicentre parallel group study. The total duration will be 5 years with patient recruitment over 4 years and an individual observation period of 1 year. 300 participants from 43 study centres, hospitals and private practices were recruited. The study will run for one year and aims to determine, whether there is an advantage with regard to HbA1c levels when (a) a regular three-monthly HbA1c or (b) a weekly 4-point glucose profile is taken and reported.

After screening, patients will be assigned at random to one of the following study arms:

1. no regular blood-glucose self-monitoring, no regular HbA1c
2. regular blood glucose self monitoring, no regular HbA1c
3. no regular blood glucose self monitoring, regular HbA1c
4. regular blood glucose self monitoring, regular HbA1c

The control for all participants is that urinary glucose should be monitored at least once a day, preferably in the late morning, as the highest increase in plasma glucose level occurs after breakfast.
