ABSTRACT
Recent interest in search tools for Clinical Decision Support (CDS) has dramatically increased. These tools help clinicians assess a medical situation by providing actionable information in the form of a select few highly relevant recent medical papers. Unlike traditional search, which is designed to deal with short queries, queries in CDS are long and narrative. We investigate the utility of applying pseudo-relevance feedback (PRF), a query expansion method that performs well in keyword-based medical literature search to CDS search. Using the optimum combination of PRF parameters we obtained statistically significant retrieval efficiency improvement in terms of nDCG, over the baseline.

Medical Question Answering for Clinical Decision Support
CIKM '16: Proceedings of the 25th ACM International on Conference on Information and Knowledge ManagementThe goal of modern Clinical Decision Support (CDS) systems is to provide physicians with information relevant to their management of patient care. When faced with a medical case, a physician asks questions about the diagnosis, the tests, or treatments ...
Mining diabetes complication and treatment patterns for clinical decision support
CIKM '13: Proceedings of the 22nd ACM international conference on Information & Knowledge ManagementThe fast development of hospital information systems (HIS) produces a large volume of electronic medical records, which provides a comprehensive source for exploratory analysis and statistics to support clinical decision-making. In this paper, we ...
Clinical decision support system and hospital readmission reduction: Evidence from U.S. panel data
AbstractUsing a large-scale panel of U.S. hospitals across health referral regions (HRRs), we empirically examine how a hospital's and its neighboring hospitals' adoption of the Clinical Decision Support System (CDSS) (and their meaningful use ...
Highlights- Adopting a clinical decision support system is associated with a significant reduction in the hospital readmission rates.
