This document discusses the concept of a "naked HIE", which is described as an open health information exchange that provides seamless access to all available patient information through any application, while maintaining accurate patient and provider identities and respecting privacy policies. The goals of a naked HIE include enabling information sharing to demonstrate value to participants, supporting meaningful use requirements, and helping to improve care and outcomes. Roadmaps are presented for using a naked HIE to connect various healthcare organizations and share different types of clinical data over time in order to increase efficiency, quality, and patient satisfaction.
