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. 1. Maximum sensitivity—retrieves the largest number of relevant results
    2. 2. Maximum specificity—retrieves somewhat fewer relevant articles but minimizes the number of irrelevant or lower-quality articles
    3. 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.
