A request distribution unit, an SO acquisition request reception unit, a creation request issuance unit, and an authorization unit are added to the clinical-path management server. The request distribution unit distributes an SO acquisition request and an access request for access to a CP. The SO acquisition request reception unit receives an SO acquisition request from a patient terminal. The creation request issuance unit issues an SO creation request to an SO attending doctor responsible for an SO. When the creation request is issued, the authorization unit grants editing authority to edit the CP of the patient requesting the SO. The authorization unit grants editing authority by updating authority management information stored in an authority management information storage unit.
