Clinical practice guidelines (CPG) are instrumental in standardizing the quality
and delivery of care across different practitioners, departments and
institutions. Health practitioners will use current best evidence to validate or
supplement their understanding of CPG. This study investigates the potential of
supplementing computerized CPG with relevant best evidence sourced from reliable
medical literature repositories. A web-enabled Best-evidence Retrieval and
Delivery (BiRD) system facilitates autonomous retrieval of pertinent medical
literature with respect to user-specified content from a GEM-encoded CPG. A
multilevel literature search strategy categorizes the search towards predefined
clinical query intentions, and subsequently filters insignificant medical terms.
The resultant is a highly focused medical literature search query that is
objectively derived from CPG content. The technical architecture comprises
existing medical language processing tools and vocabularies, together with newly
developed tools to automatically generate optimum search queries, retrieve
medical articles from MEDLINE, and embed the articles within XML-based CPG.
