title: Self-monitoring of blood glucose as part of a multi-component therapy among non-insulin requiring type 2 diabetes patients: a meta-analysis (1966-2004).
abstract: OBJECTIVE
  To determine if therapeutic management programs that include self-monitoring of blood glucose result in greater HbA1c reduction in non-insulin-requiring type 2 diabetes patients compared to programs without blood glucose self-monitoring.
  
  
  METHODS
  Electronic databases including MEDLINE (1966-2004), Cochrane Database of Systematic Reviews, EMBASE (1950-2004), Centre for Reviews and Dissemination (CRD) and the Online Index Journals of the American Diabetes Association (ADA 1978-2004) were searched. Personal collections of investigators were also explored. Randomized controlled trials comparing HbA1c reduction in therapies with and without blood glucose self-monitoring among adult, non-insulin-treated type 2 diabetes patients were selected. Studies on patients who are pregnant, taking insulin, troglitazone or experimental drugs were excluded. Out of 14 potentially useful randomized controlled trials on self-monitoring of blood glucose in non-insulin treated type 2 diabetes patients, eight studies with a total of 1307 subjects were included in the analysis. Two independent reviewers assessed the quality of studies.
  
  
  METHODS
  The effect of SMBG was assessed by means of meta-analysis of the difference in HbA1c reduction between self-monitoring and non-self-monitoring groups.
  
  
  RESULTS
  Antidiabetic therapies that included blood glucose self-monitoring as part of a multi-component management strategy produced a mean additional HbA(1c) reduction of -0.39% (95%CI: -0.54%, -0.23%) under the fixed effects model and -0.42% (95%CI: -0.63%, -0.21%) under the random effects model, when compared to therapies that did not. Heterogeneity among studies was not statistically significant.
  
  
  CONCLUSIONS
  Multi-component diabetes management programs with self-monitoring of blood glucose result in better glycemic control among non-insulin-using type 2 diabetes patients.
