Since the Diabetes Control and Complications Trial demonstrated the su
bstantial benefits of tight glycaemic control there has been renewed i
nterest in the application of information technology (IT) based techni
ques for improving the day-to-day care of patients with diabetes melli
tus. Computer-based educational approaches have a great deal of potent
ial for patient use, and may offer a means of training more health-car
e professionals to deliver such improved care. In this article the pot
ential role of IT in diabetes education is reviewed, focusing in parti
cular on the application of compartmental models in both computer-base
d interactive simulators and educational video games. Close attention
is devoted to practical applications-available today-for use by patien
ts, their relatives, students and health-care professionals. The novel
features and potential benefits of such methodologies are highlighted
and some of the limitations of currently available software are discu
ssed. The need for improved graphical user interfaces, and for further
efforts to evaluate such programs and demonstrate an educational bene
fit from their use are identified as hurdles to their more widespread
application. The review concludes with a look to the future and the ty
pe of modelling features which should be provided in the next generati
on of interactive diabetes simulators and educational video games.
