Modelling Medical Time and Expertise. Example of the Hospital Stay Duration in Diagnosis Related Groups Data Bases

The paper deals with medical temporal scales based on both the chronologic time of the physician who observes the patient, the proper inner time of the patient (related to the circadian rhythms of his major physiologic variables) and the disease duration, estimated here by using the hospital stay (for this pathology) duration. We show that patients inside homogeneous Diagnosis Related Groups can be treated through a network of co-expertise identified by using Internet facilities and based on medical co-publication networks.
