Background:
Self-monitoring of blood glucose (SMBG) is essential in diabetes care, but little is known on how it is done and on robustness of instruments routinely used by patients.
Aim: To assess the overall quality of blood glucose results, and to study associations between patient characteristics, use of self monitoring, analytical quality, and metabolic control.
Methods: Patients were from 65 general practices and a hospital outpatient clinic in a county in Norway. They filled in a questionnaire and performed two glucose measurements during a study visit.
Results: 9% of hospital patients and 40% of GP patients did not perform SMBG. Of eligible patients, 153 clinic patients and 261 GP patients participated (response rate 75%); 2/3 used insulin. About 1/3 had started SMBG themselves, and 1/3 had chosen their current meter based on advice from health care personnel. 51% were self-educated in SMBG, and 38% performed SMBG at least 7 times/week. 54% of glucose measurements were within ±10% of the reference method result, and the difference between the two SMBG results was =Conclusion:
The quality of glucose self-measurements was poorer than what is recommended. This can be due to a lack of education concerning acquisition and use of instruments. Metabolic control was not associated with the way SMBG was performed including the analytical quality of glucose measurements.
