Clinical Queries from McMaster University - an Ovid Exclusive!
Developed by Ontario’s McMaster University as part of the Hedges Project - which was funded by the U.S. National Library of Medicine (NLM) - Clinical Queries are scientifically validated filters that generate precise search results in major clinical research areas.
Who Uses Embase in the Medical Device Industry?
- • Anyone researching the track record of competitors—Emtree links trade names to manufacturer’s name
- • Compliance officers monitoring regulatory requirements and safety data
- • Quality assurance groups implementing and monitoring testing and other quality processes
- • Basic scientists working in the lab—Embase indexes over 3,000 general and medical device terms
- • Device marketers seeking competitive intelligence
- • Display as search limits in the Ovid interface
- • Give users the flexibility to apply filters that achieve 1 of 3 types of search results:
-
- 1. Maximum sensitivity—retrieves the largest number of relevant results
- 2. Maximum specificity—retrieves somewhat fewer relevant articles but minimizes the number of irrelevant or lower-quality articles
- 3. Balance of sensitivity and specificity
- • Filters can be used with 8 purpose categories:
- • Causation (etiology) • Economics • Reviews
- • Clinical Prediction Guide • Prognosis • Therapy
- • Diagnosis • Qualitative
How are Clinical Queries developed?
- • Contributors include McMaster University research staff, NLM members, clinicians, and medical librarians.
- • Terms were compiled manually, using a peer-reviewed process, and filters were developed and validated using automated, computerized methodologies.
