Abstract

Aim: To assess agreement between meter and diary self monitoring of blood glucose (SMBG)records, over a year, in a sample of patients with type 2 diabetes.Methods: Meter and diary records were available, for 95 individuals, who took part in theEfficacy of self monitoring of blood glucose in patients with newly diagnosed type 2 diabetesstudy.Pearson’s correlation coefficient was used to explore the relationships between the typesof error. Maximum likelihood estimation was used to explore changes over time through astructural equation modelling approach. Paired samples t-tests were used to determine ifthe presence of errors led to a significant difference between the mean diary and meterSMBG concentrations or coefficients of variation. Multiple regression was used to explorepossible predictors of the error indices.Results: Mean over-reporting, under-reporting, concordance and overall reliability were8.4%, 10.0%, 83.5% and 71.3%, respectively. The first week of monitoring had significantlymore under-reporting, over-reporting and less concordance and overall reliability thansubsequent weeks. The majority of concordance errors were not clinically significant. Thosethat were, tended to occur during the first three months of monitoring. Participants’ at onetrial site were significantly more likely to have recording errors than those at the largest site.Conclusions: Error levels were similar to those described previously in type 1 diabetes andthere was a suggestion of an initial learning curve for record keeping. For some individualsdiary records would not be considered acceptable if held to the same standards as bloodglucose meters.
