Embedding a Medical Search Engine Within an Electronic Health Record.

This study investigates an information retrieval tool embedded in an electronic health record (EHR). 1-Search provides a single search for retrieving information from a variety of content sources. 1-Search's usefulness and impact were determined by measuring the extent of physicians' information needs, pre- and post-implementation user satisfaction, and the impact of 1-Search on clinical decision-making. Results support incorporation of 1-Search into the EHR, the continued use of 1-Search, and further development.
