A method of managing access to a healthcare information system of a healthcare establishment communications network. The method comprises receiving data regarding a wirelessly detectable tag associated with a clinician; determining whether the clinician is positioned relative to a terminal of the healthcare establishment communications network such that a proximity condition is satisfied based at least in part on the data regarding the wirelessly detectable tag; responsive to the proximity condition being satisfied, providing an opportunity for authentication of the clinician; and responsive to successful authentication of the clinician, establishing a session for the clinician between the terminal and the healthcare information system. The ability to detect proximity of clinician facilitates the process by which the clinician may access the healthcare information system, while the requirement for authentication of the clinician minimizes the risk of data being made available to an unauthorized party.
