NCT01460459

Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • HbA1c

    The main study parameter is glycemic control. Glycemic control is measured by HbA1c. A difference of 0.5% (\> 5.5 mmol/mol) in HbA1c between groups is considered to be relevant.

    9 months

Secondary Outcomes (1)

  • quality of life

    9 months

Study Arms (3)

high frequency of SMBG

EXPERIMENTAL

Patients are instructed to measure their blood glucose concentrations 4 times per day (pre-prandial and before bedtime) one day weekly in group A.

Behavioral: a specific frequency of SMBG

middle frequency of SMBG

EXPERIMENTAL

Patients are instructed to measure their blood glucose concentrations 4 times per day (pre-prandial and before bedtime) one day per two weeks in group B.

Behavioral: a specific frequency of SMBG

low frequency of SMBG

EXPERIMENTAL

Patients are instructed to measure their blood glucose concentrations 4 times per day (pre-prandial and before bedtime) Group C: one day monthly

Behavioral: a specific frequency of SMBG

Interventions
