Using automated extraction from the medical record to access biomedical literature.
Mendonca, Eneida Abrantes.

Using automated extraction from the medical record to access biomedical literature. - 134 p.

Adviser: James J. Cimino.

Thesis (Ph.D.)--Columbia University, 2002.

The practice of evidence-based medicine, which gained popularity in the last decade, has encouraged clinicians to understand and utilize critically appraised published research evidence. Despite the increased availability of information and the increased number of clinicians who routinely perform their own searches, clinicians still find comprehensive review of biomedical literature unmanageable. Attention has also been given to the assessment of medical errors and other adverse events in health care. Researchers have shown that most of these failures have in common problems in the access to information. Decision support tools have been advertised as capable of substantially improving health care quality and reduce medical errors. Electronic medical records may provide these tools with useful information about the patient that may result in recommendations that are better tailored to individual patients, and eventually associated with improved outcomes.

520 $a The practice of evidence-based medicine, which gained popularity in the last decade, has encouraged clinicians to understand and utilize critically appraised published research evidence. Despite the increased availability of information and the increased number of clinicians who routinely perform their own searches, clinicians still find comprehensive review of biomedical literature unmanageable. Attention has also been given to the assessment of medical errors and other adverse events in health care. Researchers have shown that most of these failures have in common problems in the access to information. Decision support tools have been advertised as capable of substantially improving health care quality and reduce medical errors. Electronic medical records may provide these tools with useful information about the patient that may result in recommendations that are better tailored to individual patients, and eventually associated with improved outcomes.
520 $a I have focused my research on the case-specific evidence present in patient medical record (e.g., clinical data and demographics), and the use of this evidence to rank biomedical literature. My ultimate goal is to improve the way retrieved biomedical literature is presented by identifying critical information in the individual medical record that is useful for determining the relevance of literature data, also called research evidence. In preliminary studies, I evaluated techniques for automated knowledge extraction from biomedical literature, and the use of natural language processing and indexing theory to identify critical information in an individual's medical record. I then applied the result of these studies to build knowledge-based approaches to rank citations retrieved from biomedical literature databases.
520 $a The results of the research presented here support the belief that clinical data can facilitate presentation of biomedical literature. The use of conceptual graph representation and graph matching techniques, as well as indexing measures (<italic>tf*idf</italic>) correlated significantly with the average of physicians when judging the relevance of citations to the care of an individual patient. Additional studies are needed in order to understand if this performance is acceptable in a clinical environment.
