Abstract: A nurse call system of the present disclosure includes: a nurse call slave unit; a nurse call master unit; a mobile terminal; an access point for relaying communications between the mobile terminal and the nurse call master unit; a private branch exchange configured to control communications between the nurse call slave unit and the mobile terminal; and a chat server configured to generate a chat room to be delivered to the mobile terminal in response to a call originated from the nurse call slave unit, in which the chat server generates a chat room with in-charge healthcare workers in charge of a subject patient who originated a call using the nurse call slave unit and a nearby healthcare worker assumed to be at a location closer to the subject patient than the in-charge healthcare workers are as users, and provides the chat room to each mobile terminal.
