The use of personal information webs: convergence of enterprise information sources at the point of care

摘要

Scott and White is the largest integrated healthcare delivery system in the Southwest. The rapid and continual expansion of readily available patient-related computerized information from multiple sources and systems within our enterprise over the last ten years has now enabled our development of a user-friendly, yet secure, access module to meet our clinicians' point-of-care information needs. We have developed and begun implementation of these individualized "Personal Information Webs". Each clinician is provided, with rigorous security and confidentiality measures built in, a personal web portal to our enterprise intranet. This page has predetermined navigational parameters and functionalities that are based on a rigorous role-based user security profile model. The portal provides its owner bi-directional communication with our back-end enterprise business and clinical information resources by communicating with them at a "virtual XML document" level, using a personal information broker/server as an intermediary.
