Abstract

A material search unit searches for an old medical material corresponding to a new medical material from a material correspondence information DB. A clinical path information search unit searches for clinical path information in which the new and old medical materials are used for medical care from the clinical path information DB, and a record information acquisition unit acquires the number of days of hospitalization indicating treatment effects of the new and old medical materials from the clinical path information which has been searched for. An introduction effect analysis unit calculates the average numbers of days of hospitalization of the new and old medical materials, and divides the average number of days of hospitalization of the old medical material by the average number of days of hospitalization of the new medical material, to calculate a rate of a decrease in the average number of days of hospitalization of the new medical material relative to the old medical material as introduction effects of the new medical material.
