Abstract

A medical communication system (10) comprises peer devices (44, 46) which provide medical services which are used for patient monitoring, patient management or other medical procedures involving patients and/or clinicians. A mobile device (12) includes a short-range interface device (22) for discovering peer devices (44, 46) and associated peer devices services (66). A positioning component (14) determines a location of the mobile device (12). An identification component (60) reads a patient identification device (48) and a clinician identification device (50) and identifies a patient (32) and a clinician (30) at the location of the mobile device (12). A visibility manager (120) limits information and services available to the mobile device (12) to current context relevant information and services which are based at least on one of the identity of the patient (32), the identity of the clinician (30), and the identified mobile device location.
