AUTHORS ' CONCLUSIONS Computer-based diabetes self-management interventions to manage type 2 diabetes appear to have a small beneficial effect on blood glucose control and the effect was larger in the mobile phone subgroup .
There is no evidence to show benefits in other biological outcomes or any cognitive , behavioural or emotional outcomes
BACKGROUND Diabetes is one of the commonest chronic medical conditions , affecting around 347 million adults worldwide .
Structured patient education programmes reduce the risk of diabetes-related complications four-fold .
Internet-based self-management programmes have been shown to be effective for a number of long-term conditions , but it is unclear what are the essential or effective components of such programmes .
If computer-based self-management interventions improve outcomes in type 2 diabetes , they could potentially provide a cost-effective option for reducing the burdens placed on patients and healthcare systems by this long-term condition .
OBJECTIVES To assess the effects on health status and health-related quality of life of computer-based diabetes self-management interventions for adults with type 2 diabetes mellitus .
Adoption and Use of an Online Patient Portal for Diabetes (Diabetes-STAR)
Online patient portals , which provide patients with personal information and facilitate electronic doctor-patient communication , can help patients manage chronic diseases . These systems will be most beneficial if they have broad and durable appeal . In a r and omized trial , we compared a portal providing generic diabetes self-management information to one providing personalized information ( Diabetes-STAR ) . We assessed ( 1 ) the characteristics of patient-users  and ( 2 ) whether including personalized content promotes sustained use
