Study information
Scientific title
The effect of self monitoring of blood glucose and urine glucose relative to usual care without self monitoring on diabetes related distress and glycaemic control in patients with type 2 diabetes who are not using insulin
Acronym
IN CONTROL
Study hypothesis
By applying self monitoring of glucose, patients with Diabetes Mellitus type two (DM2) may cope more independently with their disease. Self monitoring can aid in diabetes control by giving the patient the ability to make appropriate day-to-day treatment choices in diet and physical activity as well as in medication. Furthermore, it will improve a patient's recognition of hypoglycaemia or severe hyperglycaemia, and enhance patient empowerment regarding the effects of lifestyle and medication on glycaemic control and thereby provide a better perceived quality of life.

Condition
Diabetes Mellitus type two (DM2)
Intervention
A stratified, randomised six-arm clinical trial among DM2 patients with an Hb1Ac of 7.0% or above who are not using insulin. Eligible and consenting subjects will be randomly assigned to the intervention groups Self Monitoring of Blood Glucose (SMBG) or Self Monitoring of Urine Glucose (SMUG), or to the control group.
Before randomisation the patients will be stratified according to treatment (i.e. using Sulphonylureas [SU] or not [Non-SU]). The SMBG and SMUG will be an integral part of a wider educational strategy; the intervention groups and the control group will receive a standardised treatment program to change their diet and lifestyle.
In addition, patients in the SMBG group will be educated to use the SMBG-device and patients in the SMUG-group will be educated to use the urine tests. They will learn to know and understand the ranges of test results and what steps to take in response to a high or low, or positive or negative reading.
The intervention groups will perform self-monitoring according to standard testing frequency instructions during one year.

b. physical activity (Short Questionnaire to Assess Health enhancing physical activity [SQUASH])
5. Changes in medication use
6. Compliance
7. Medical care utilisation
All secondary outcomes will be assessed at baseline, 6 and 12 months after inclusion.
