Abstract: A memory unit stores medical information related to a patient's dangerous behavior and extracted in advance from judged medical record information which is medical record information identifying the dangerous behavior by being linked to an incident report about the patient's dangerous behavior. A relation evaluation unit acquires unjudged medical record information, to which the incident report is not linked, and evaluates a relation between the unjudged medical record information and a possible dangerous behavior of the patient corresponding to the unjudged medical record information on the basis of the medical information related to the dangerous behavior stored in the memory unit. A prediction unit predicts the patient's dangerous behavior corresponding to the unjudged medical record information according to an evaluation result of the relation evaluation unit. A data reporting unit reports a prediction result of the prediction unit.
