[PROTIS, an expert system applied to the treatment of non-insulin-dependent diabetes. Evaluation of its efficacy]. / PROTIS, un système expert appliqué au traitement du diabète non insulino-dépendant. Evaluation de son efficacité.

PROTIS is an expert system devised to help general practitioners in the treatment of diabetes. It provides weighted results in ranking order from the most indicated to the most contra-indicated treatment. The reliability of PROTIS was tested comparatively by asking the system and two diabetologists involved in its design to analyze 250 clinical cases. The therapeutic advice given by PROTIS was considered satisfactory in 91.2% of the cases and erroneous, though without vital consequences, in 4.4%. The system was unable to propose any treatment in 4.4% of the cases. Most errors or non-responses could be corrected. This evaluation showed that PROTIS faithfully reproduces the reasoning of diabetologists and could serve as an example of what an expert system could do for the general practitioner.
