    Improving Access to Clinical Information in an Emergency Department: a Qualitative Study
    (2008-11-10) Kijsanayotin, Boonchai; Du, Jing; Theera-Ampornpunt, Nawanan; Gurses, Ayse; Speedie, Stuart M.
    We studied the information flow in an emergency department (ED) to understand how patient information flows between providers and how information from a computerized ambulatory system, which was not well integrated with the hospital information systems at the time, could be used. The study aimed to identify possible methods that could push information from an ambulatory EHR system to providers with minimal interference with the ED’s current workflow. The ED’s information flow was mapped and a strategy for making ambulatory encounter information available was identified.

    Creating a Large Database Test Bed with Typographical Errors for Record Linkage Evaluation
    (2008-11-11) Theera-Ampornpunt, Nawanan; Kijsanayotin, Boonchai; Speedie, Stuart M.
    Health information exchange across multiple organizations requires a method or algorithm to optimally link records of the same individuals using demographic data. Selecting the best record linkage algorithm requires an evaluation to determine its sensitivity and specificity. This evaluation is facilitated by a large database test bed that closely reflects a real world population and takes into account the potential data entry errors that unfortunately occur in real-world databases. This study investigated the synthesis of such a database.

    Measurement of Health Information Technology Adoption: A Review of the Literature and Instrument Development
    (2009-08) Theera-Ampornpunt, Nawanan
    Studies have shown that adoption and use of health information technology (IT) plays a role in improving the quality and efficiency of care. There are many empirical studies on health IT adoption and use in the U.S. and other Western countries, but little is known about the state of health IT adoption in Thailand. In addition, there exist few articles that focus on the theoretical and methodological aspects of health IT adoption. This study begins with the review of theories related to IT adoption from several fields including health informatics, information systems, and innovation diffusions. A critical review of these theories offer a perspective on the conceptualization of IT adoption, which would help researchers conducting IT adoption studies on their framework development. A methodological review of studies involving health IT adoption and use also helps gain valuable insights on the study design, methods, and measurement of health IT adoption that allow health IT adoption researchers to conduct better studies. Insights from the theoretical and methodological reviews lead to the proposed modification of an existing conceptual framework of health IT adoption called IT sophistication. The modified IT sophistication construct focuses on 3 different aspects related to health IT adoption: the technologies and information exchange that constitutes an organization’s IT infrastructure, the functions the available technologies offer, and the management and cultural practices that are known to influence successful adoption and use of health IT. A survey instrument was developed based on this framework, with the focus on measuring the hardly known state of health IT adoption in Thai hospitals.

    Clinical Symbol Sense Inventory
    (2012-10-31) Moon, Sungrim; Pakhomov, Serguei; Melton, Genevieve
    Although clinical texts contain many symbols, relatively little attention has been given to symbol resolution by medical natural language processing (NLP) researchers. Interpreting the meaning of symbols may be viewed as a special case of Word Sense Disambiguation (WSD). One thousand instances of four common non-alphanumeric symbols (‘+’, ‘–’, ‘/’, and ‘#’) were randomly extracted from a clinical document repository and annotated by experts. De-identified data are available for researchers.

    Clinical Abbreviation Sense Inventory
    (2012-10-31) Moon, Sungrim; Pakhomov, Serguei; Melton, Genevieve
    A sense inventory is a collection of abbreviations and acronyms (short forms) with their possible senses (long forms), along with other corresponding information about these terms. For our comprehensive sense inventory for clinical abbreviations and acronyms, a total of 440 most frequently used abbreviations and acronyms were selected from 352,267 dictated clinical notes. 949 senses of each abbreviation and acronym were manually annotated from 500 random instances within clinical notes and lexically aligned with 17,359 long forms of the Unified Medical Language System (UMLS), 5,233 long forms of Another Database of Abbreviations in Medline (ADAM), and 4,879 long forms in Stedman’s Medical Abbreviations, Acronyms & Symbols (4th edition).

    Surgical Action Predicates with Mapping
    (2012-10-31) Wang, Yan; Pakhomov, Serguei; Melton, Genevieve
    The ‘procedure description’ section in operative note contains a significant amount of description of actions performed during an operation. The action predicates (e.g., fill, incision, irrigate, etc.) encode predicative relations between nominal arguments (e.g., chamber, viscoelastic, Murphy hook, L5 root, antibiotic solution). These predicate arguments convey the important details about actions performed during a procedure. This dataset includes frequent action predicates collected from 362,310 operation narratives obtained from University of Minnesota-affiliated Fairview Health Services with the UMLS and SPECIALIST lexicon mapping.
