In cooperation with a first database, a problem preparation supporting unit supports the preparation of nursing problem items for patients. Based on the nursing problem items prepared, a plan preparation supporting unit supports the preparation of nursing care plans by conducting search through a second database. In cooperation with a third database, a specification unit specifies an implementation of nursing items contained in the prepared nursing care plan. When a communication unit receives an implementation result of the nursing items, the communication unit outputs the result to a recording unit. A nurse enters an evaluation of the implementation result of the nursing items to an operation apparatus. The evaluation entered is recorded in the recording unit. Among the nursing problem items stored in the recording unit, the nursing items contained in the nursing care plans, the implementation results and the evaluations, the management unit associates them with one another by bringing them into correspondence with each other.
