No.1: Databases and planning a search
Databases
Journal references
- Medline
- Over 13 million citations from more than 4,600 journals on biomedicine, including the allied health fields and the biological and physical sciences, humanities, and information science as they relate to medicine and health. Various files of Medline are available, starting from Old Medline (1950 - 1965), through to Medline In-Process & Other Non-Indexed Citations for very recent articles. To find literature from 1950 - 1965 use both Old Medline (using thesaurus and keyword) plus Medline 1950 to present (using thesaurus). See Searching and saving in Ovid and Managing Ovid search results for search help.

Editors screen top clinical journals, identifying studies that are both methodologically sound and clinically relevant. An expanded abstract includes critical appraisal of the value of the article for clinical practice.

Drug information
- Toxnet

- MIMS Online

Planning a search
- State the topic in a sentence or question and identify the main concepts or terms.
- Sample Search Topic:
- Can migraine or cluster headaches be treated effectively with sumatriptan?
- Key concepts:
- 1. Migraine headache
- 2. Cluster headache
- 3. Sumatriptan
- Consider search refinements to limit the retrieval to specific aspects of a topic, such as:
- Human or animal studies
- Male or female subjects
- Age groups, e.g. adolescents, infants
- Time periods
- Languages
- Consider the potential use of the information. A comprehensive search covering several years would be required for grant proposals and research purposes, while a few very precise articles would be more useful for a patient care situation.
- Use the thesaurus (controlled vocabulary) to express main concepts. Use keywords if no appropriate thesaurus term exists.
- Combine the main concepts or search terms using the Boolean Operators - OR, AND. Stating the topic in narrative form not only helps to identify all key terms, but also establishes the relationship of the terms to each other.
The relationship of the key terms in this sample search topic would be expressed as: (Migraine headache or cluster headache) and sumatriptan.
