Background: The objective of this systematic review was to examine the comparative effectiveness of individual education and group education for adults with type 2 diabetes mellitus.Method: This review considered only randomised controlled trials (RCTs) and controlled clinical trials assessing the effectiveness of group education when compared to individual education. The review included trials in which all participants were adults over 18 years of age, of either sex, diagnosed with type 2 diabetes. The Joanne Briggs Institute’s systematic review process was used for this review including, search strategy, critical appraisal, data collection and analysis. A comprehensive search using all identified keywords and index terms was undertaken in major databases (MEDLINE, CINAHL, Cochrane Central Register of Controlled Trials). Each paper was assessed by two independent reviewers for methodological quality before being included in the review using The Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument (JBI-MAStARI). Meta-analyses were performed using Review Manager 5 software (2011). Results: This systematic review included four RCTs, and one Quasi-experimental prospectively controlled clinical trial. All five included studies assessed the effectiveness of group education compared to individual education on HbA1c levels and the pooled data from two studies found no significant differences in reduction of HbA1c after 6 months of the intervention (WMD 0.00, 95{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465} CI -0.21 to 0.22, p=0.96), however significant heterogeneity was observed (I2=90{6e6090cdd558c53a8bc18225ef4499fead9160abd3419ad4f137e902b483c465}; P=0.002). Conclusion: This review found that both group and individual education are efficacious for adults with type 2 diabetes and is consistent with findings from other reviews. However, in light of the small number of studies included in this review, the nature of the participants and the heterogeneity of the interventions no definite conclusions can be formed on the most effective method of education delivery in terms of patient outcomes.
