Self-monitoring of Blood Glucose in Insulin-treated Patients With Type 2 Diabetes

Primary Objective: The objective of the study is to investigate the effect of a specific frequency of Self-monitoring of blood glucose (SMBG) on glycemic control and quality of life in patients with type 2 diabetes and who are in stable good glycemic control and using 1 insulin injection daily. The research question is: Does a less intensive frequency of SMBG in insulin-treated patients with type 2 diabetes, who are in stable good glycemic control, using 1 insulin injection daily, lead to a clinically relevant increase of HbA1c (an increase of 0.5%) and what is the effect on quality of life? Secondary objectives: The secondary objectives is to investigate the effect of a specific frequency of SMBG on the number of hypo and hyper glycaemia, number of extra diabetes-related contacts with the health care provider, and the diabetes medication.
