AbstractMicrocomputers have been used in our hospital for the past five years to summarize data from patients and to remind us to carry out routine tests. Recently, we have shown computer data on the screen to patients; this helps us to explain and discuss the monitoring of their condition with them.Unlike some other systems, general data as well as data on self‐monitored blood glucose levels are recorded in our computer system. The data consist of five categories: personal profile, treatment, etiological research, indices of control and data for checking complications.The analysis and evaluation of our system are done by the modes of display, statistical calculations, early detection of complications and graphics.The system is compatible with input from a keyboard, optical character readers and interface to a glucose meter with a memor
