The effects of isolated telephone interventions on glycemic control in type 2 diabetes: a literature review

Abstract

A systematic literature review of studies published between 1990 and 2008 was conducted to evaluate the impact of isolated telephone interventions on glycemic control in adults with type 2 diabetes. Eight randomized controlled trials met the inclusion criteria. Overall, the interventions had mixed effects on glycemic control, suggesting further research is needed in this area. Current evidence does not support isolated telephone interventions to improve glycemic control in type 2 diabetes mellitus; well-designed studies to establish the effectiveness of this potentially cost-effective modality can be an important step in addressing the diabetes epidemic.
