Linking multiple heterogeneous data sources to practice guidelines.

Abstract

The BiliLIGHT system is a World Wide Web (Web) based system that integrates an interactive clinical practice guideline with real-time patient-data retrieval from remote heterogeneous data sources to help clinicians manage newborn jaundice at the point of care in three clinical settings. We briefly describe the system, how actual information exchange of medical data across institutional boundaries was achieved, and how the data were connected to a CPG. In particular, we examine the requirements for patient identification, exchange protocols, authentication, and a standard vocabulary.
