Position Description:

We are seeking a Researcher (with background in IR, LM, DM/TM or NLP) for a project that involves the study of Electronic Medical Records.  Please review the information below and don't hesitate to contact Efthimis Efthimiadis (efthimis at u.washington.edu) or Ken Hammond (Kenric.Hammond at va.gov) for additional information.


TITLE OF PROJECT:  Assessing Information Value in Computerized Patient Care Documentation Systems

1. BACKGROUND AND PURPOSE OF RESEARCH.

Computerized patient care documents (CPD), consisting of progress notes, summaries, and reports documenting medical care are a key part of modern computerized health care information systems. On-line documents are more accessible and legible than paper records, but the transition to computer systems has introduced new challenges. Computerized documents differ from traditional documents: document writers may copy text from other documents; ancillary data is frequently inserted automatically; and templates assisting text entry introduce boilerplate text. Shortcuts aid writing documents but often result in poor readability and reduce the value of on-line documentation. Copying can propagate errors and obscure the original source of information. Data overload is a significant problem: Nationally, Veterans Administration (VA) systems currently store over 700 million patient documents. Individual charts may contain hundreds of documents. Computerized medical record users can be hard pressed to find the specific information they need amid a flood of potentially useful information, because the time available to retrieve information from documentation is constrained.

Improved patient records will benefit patients, practitioners, and anyone else who uses them. The objective of this part of the research project is to analyze and characterize a large dataset of medical records using information retrieval, language modeling, text classification and mining, and natural language approaches.


2. DATA SET

The VISN 20 Dataset, consists of approximately 18 million documents belonging to about 80,000 veterans, and has been extracted from computerized records kept at the VISN 20 data center (Vancouver, WA). The VISN 20 dataset is available as a SQL Server relational database, and it is located in a secure storage network at the HSR&D offices in Seattle.
