PROBLEM TO BE SOLVED: To perform an appropriate instruction for users.SOLUTION: According to a communication system 1, a server 10 determines, according to disease severity of a user (a healthy person or a home care patient), to which, in a plurality of communication terminals 30 for every instructor, a users query for a response is transmitted. In concrete terms, for example, when a user of a communication terminal 20 is a healthy person, the server 10 determines to transmit the query for the response from the communication terminal 20 to a communication terminal 30 of a health nurse (in charge of healthy persons). Alternatively, when a user of the communication terminal 20 is a home care patient with high disease severity, the server 10 determines to transmit a query for a response from the communication terminal 20 to a communication terminal 30 of a doctor or a nurse.COPYRIGHT: (C)2013,JPO&INPIT【課題】ユーザに対して適切な指導を可能とする。【解決手段】通信システム1によれば、サーバ10は、ユーザ(健常者或いは在宅療養者)の病度に応じて、ユーザの質問回答を、指導者毎の複数の通信端末30の何れに送信するかを決定する。具体的には、例えば、サーバ10は、通信端末20のユーザが健常者であれば、通信端末20から保健師(健常者担当)の通信端末30へ、質問回答を送信させる決定を行う。また、例えば、サーバ10は、通信端末20のユーザが重度の病度の在宅療養者であれば、通信端末20から医師・看護師の通信端末30へ、質問回答を送信させる決定を行う。【選択図】図2
