An internet-based glucose monitoring system did not improve glycemic control in type 1 diabetes

This randomised trial in Pediatric Diabetes looked at whether sending blood glucose levels over the internet to carers resulted in better glycemic control among adolescents with type 1 diabetes.

However, the trial only had 70 participants, and around one third did not comply with the intervention, rendering the results almost meaningless.  Although the authors carried out a sub-group analysis on those that complied, the observed improvement in HbAc1 was not statistically significant.

Appraisal guide

Readers of this paper should consider:

  • The small sample size
  • The lack of compliance
  • The mechanism by which the intervention might improve glycemic control.

I am an information scientist with an interest in making knowledge from systematic research more accessible to people who need it. This means you. I've been attempting this in the area of Evidence-Based Health Care since 1995. So far the results have been mixed. For some reason we expected busy clinicians to search databases and appraise papers instead of seeing patients. We also expected publishers to make the research freely available to the people who paid for it.. Ha! Hence The National Elf service.
