Modern medicine uses an increasing quantity of information. This is due to the emergence of new, diverse and complementary investigation techniques (imaging, etc.), and mostly to growing numbers of patients treated for chronic diseases in the developed countries. The double goal of enhancing the quality of health care and of controlling costs implies a need for rapid access to information available on patient history. This creates an increasing demand for better management of medical information resources, and of patient records. In the case of pathologies that are sufficiently limited and well standardised in their treatment, computerised medical records, developed in the framework of Hospital Information Systems, are being used. However, they require users to adhere strictly to a fixed, closed set of items to describe patient information.
Nevertheless, a number of applications such as ongoing patient care, evaluation of health care and clinical research use information which is predominantly available in narrative patient discharge summaries, in the form of "free text." These reports synthesise the relevant information concerning each patient, and contain a wealth of data regarding patient history, current diagnoses, and current and suggested subsequent treatments. They constitute a widely available, low cost source of reliable information, which is flexible and can adapt to medical progress. However, available industrial technology does not allow access to this information. Project Menelas aims to design and implement a new sort of computer system using natural language processing and information retrieval techniques to fill this gap. The pilot system will offer the following services:
