The aim of the preset study was to investigate the effectiveness of structured self‐monitoring of blood glucose ( SMBG ) in insufficiently controlled insulin‐treated diabetes. A total of 86 insulin‐treated patients were randomized to a routine testing group ( RTG ; n = 43) and a structured testing group ( STG ; n = 43). The STG used a chart to record seven‐point blood glucose (BG) profile on three consecutive days per month. The primary end‐point was the glycated hemoglobin (HbA1c) at 3 months and 6 months. There were no significant differences of HbA1c between the RTG and STG at 3 months. However, the STG had significantly improved HbA1c at 6‐month follow‐up compared with the RTG ( P = 0.002). In the STG , HbA1c decreased by 0.5% from 7.9 (SD 0.5) to 7.4 (0.7)%, whereas it decreased by 0.1% in the RTG from 7.9 (0.5) to 7.8 (0.7)%. In the STG , 55% of the patients were willing to continue structured SMBG and they achieved a 0.7% decrease of HbA1c. The present findings suggest that structured SMBG significantly improves glycemic control.
