Q: What is Ovid?

Ovid is a powerful search platform that is used to build and run complex, reproducible searches on different journal databases.

At Monash Health, Ovid is used search the following subscription databases: Medline, Embase, Emcare, and APA PsycInfo.

Q: What are subject headings?

Subject headings are specific words or phrases that are used to describe the topic(s) of a journal article, conference paper, or other publication. They are essentially tags or labels that are applied to publications in a consistent manner, using a pre-defined list of words or phrases. A comprehensive literature search uses subject headings in addition to keywords.

In health research, Medical Subject Headings (MeSH) are used by journal databases such as Medline and PubMed. However, Embase and Emcare use Emtree subject headings, and PsycINFO uses the APA Thesaurus of Psychological Index Terms.‚Äč

Q: What is the difference between MeSH and Emtree?

How do Emtree and MeSH differ? - taken from 

  • "Good question. Both are hierarchical controlled vocabularies for health sciences and have a similar facet structure. In fact, Embase was modeled on MeSH in 1988. Both also link to CAS registry and Enzyme Commission numbers.
  • Over time, however, Embase has differentiated itself from MeSH. While it still includes all MeSH terms, it has become a more extensive thesaurus that facilitates a more intuitive way of exploring the literature".

Q: Does Monash Health have access to CINAHL?

CINAHL is a nursing and allied health database. Monash Health does not have access to CINAHL; however, we do have alternatives such as ProQuest Nursing & Allied Health and Emcare
