DIABLOG: a simulation program of insulin-glucose dynamics for education of diabetics.

This paper presents a dialogue computer program, DIABLOG, for the education of diabetic patients with insulin therapy. Through mathematical modelling of glucose-insulin dynamics this program is able to simulate glucose and insulin profiles of a 24 h period and display them graphically as curves. The subjects could vary the carbohydrate content of meals, the injection time and dose of short-acting and intermediate-acting insulin and could switch to insulin pump therapy. For a first evaluation 22 patients with insulin-dependent diabetes mellitus tested the program and their comments were recorded by a questionnaire. The results indicate a good acceptance of the program even by patients with no previous computer experience. Further suggestions by the patients will be discussed as well.
