Comparative StudyVoice-dictated versus typed-in clinician notes: linguistic properties and the potential implications on natural language processing.
In this study, we comparatively examined the linguistic properties of narrative clinician notes created through voice dictation versus those directly entered by clinicians via a computer keyboard. Intuitively, the nature of voice-dictated notes would resemble that of natural language, while typed-in notes may demonstrate distinctive language features for reasons such as intensive usage of acronyms. ⋯ The results suggest that between the narrative clinician notes created via these two different methods, there exists a considerable amount of lexical and distributional differences. Such differences could have a significant impact on the performance of natural language processing tools, necessitating these two different types of documents being differentially treated.

Development and evaluation of a prototype search engine to meet public health information needs.
Grey literature is information not available through commercial publishers. It is a sizable and valuable information source for public health (PH) practice but because documents are not formally indexed the information is difficult to locate. Public Health Information Search (PHIS) was developed to address this problem. ⋯ Increased document collection size and enhanced result rankings improved search effectiveness from 28% to 55%. PHIS would work best in conjunction with Google or another broad coverage Web search engine when searching for documents and reports as opposed to local health data and primary disease information. PHIS could enhance both the quality and quantity of PH search results.

Using a unified usability framework to dramatically improve the usability of an EMR Module.
Electronic Medical Records (EMRs) are increasingly used in modern health care. As a result, systematically applying usability principles becomes increasingly vital in creating systems that provide health care professionals with satisfying, efficient, and effective user experiences, as opposed to frustrating interfaces that are difficult to learn, hard to use, and error prone. This study demonstrates how the TURF framework [1] can be used to evaluate the usability of an EMR module and subsequently redesign its interface with dramatically improved usability in a unified, systematic, and principled way. This study also shows how heuristic evaluations can be utilized to complement the TURF framework.

Development and use of a medication history service associated with a health information exchange: architecture and preliminary findings.
We describe our early experience with use in emergency department settings of a standards-based medication history service integrated into a health information exchange (HIE). The service sends queries from one Exchange's emergency department interface both to a local ambulatory care system and to the medication hub services provided by a second HIE. ⋯ Usage may be increasing as additional retail pharmacy data become available. Early results suggest that research and development emphasis requirements will of necessity shift from obtaining prescription medication history to finding new means to ensuring effective use.

eEvidence: Information Seeking Support for Evidence-based Practice: An Implementation Case Study.
We propose to collect freely available articles from the web to build an evidence-based practice resource collection with up-to-date coverage, and then apply automated classification and key information extraction on the collected articles to provide means for sounder relevance judgments. We implement these features into a dual-interface system that allows users to choose between an active or passive information seeking process depending on the amount of time available.
