Objectives Although self-monitoring blood glucose(SMBG) is crucial for the management of diabetes mellitus, patients tend to have less opportunity to be educated for organized instruction on SMBG. The aim of study was to evaluate the difference between the SMBG level and laboratory plasma glucose level and to investigate factors that cause error of SMBG in actual situation.
Methods 52 patients having a glucometer and doing SMBG were enrolled for this study between May and September, 2001. The performance of SMBG was evaluated by a guideline made in our institution based on the ADAs report in 1987. It was consisted of calibration of the devices, cleanliness of window, the term of validity of a strip, code consistency, fading rate of a strip, dryness of alcohol before SMBG, and quantity of blood, etc. Laboratory plasma glucose level was measured by Hitachi 731-40 autoanalyzer and was compared with SMBG level.
Results In general, the most prevalent factor that the patients kept will when performing SMBG was using unfaded strips(94.1%). The least factor that patients had kept was calibration of glucometer by themselves(13.6%). Then main cause of error of SMBE was patients incompetence of using a glucometer(76.9%). The average difference between SMBG level and laboratory glucose level in connection with patients incompetence was 22.7mg/dL.
Conclusion In this study, many patients didn't use the glucometer correctly and the main cause of misuse of SMBG was users incompetence. We suggest that a united guideline for accurate performance for using a glucometer and the standardization of the device should be established.
