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.
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.
