Abstract
While Self-monitoring of blood glucose (SMBG) has been recommended in some diabetes mellitus (DM) patients population according to the 2010 American Diabetes Association (ADA), 2007 Korean Diabetes Association (KDA), 2005 International Diabetes Federation guideline, it is excluded from a routine insurance coverage for outpatients in Korea. The objective of this study is to meta-analyze the impact of SMBG on HbA1c in non insulin-treated diabetes mellitus (NIT) DM patients. Published clinical literatures were identified through electronic database searches from inception and until May 2010. Studies were selected if they met the following inclusion criteria: 1) randomized controlled trials (RCTs), 2) comparing SMBG with non-SMBG in NIT type 2 diabetes, 3) measuring HbA1c as an outcome. Literature qualities were assessed by the Scottish Intercollegiate Guidelines Network Checklist. The mean difference of HbA1c between the 2 groups was pooled from non-heterogeneous 6 RCTs by meta-analysis using Review Manger (RevMan) Version 5.0 program. Pooled results demonstrated that SMBG is associated with a statistically significant improvement in glycemic control (mean HbA1c difference -0.23, 95%CI -0.32, -0.13). Sensitivity analysis showed that glycemic controls were significantly improved in patients with shorter study duration, more frequent self-monitoring, higher baseline HbA1c value, and without prior SMBG experiences. Conclusively SMBG is effective in improving glycemic control in NIT DM patients, but additional evidences from further researches in Korean patients and cost-effectiveness analysis would be necessary to make a suggestion for coverage expansion.
