Abstract

A patient information hub (PIH) system used in a healthcare system for the management of data documents of a patient has an implanted medical device, and a portable non-implanted unit having the capability for communicating with the IMD. The PIH system stores and manages a document list containing information of data documents of the patient and information of in which data depositories of the healthcare system the documents are stored and can be retrieved from. The retrieval of the document list from the PIH system for display on a screen of the communicating unit or transmission to an external requesting unit is made dependent on a communication operation involving the IMD and the non-implanted unit.
