Study Notes
Truncation and Wildcards
- Truncation uses a symbol (e.g. *, $, or #) to replace endings on words, allowing for variations in search results.
- Wildcards use a symbol (e.g. ?) to replace a letter in the middle of a word, useful for spelling variations between American and British English.
Boolean Logic
- Boolean logic uses three primary operators: AND, OR, and NOT, to combine keywords and generate relevant citations.
Medical Subject Headings (MeSH)
- MeSH terms provide a common and consistent language across published articles, but may be limited in scope.
- Keywords can be used as an alternative to MeSH terms.
Search Engines and Databases
- Search engines allow specific articles to be identified in a database.
- One search engine can search multiple databases, and one database can be searched using multiple search engines.
- Examples of search engines include PubMed, Ovid Medline, and ProQuest.
Conducting a Search
- When searching for phrases, enclosing them in quotes tells the database to consider the phrase as a single term.
- Keywords should be carefully selected to ensure relevant search results, considering factors such as patient demographics, condition, and treatment.
Limits and Filters
- The Limits page can be used to limit search results to specific types of articles.
Keyword Phrases
- When searching for phrases, enclosing them in quotes ensures the database considers the phrase as a single term.
Finding Research Evidence
- Government and non-governmental organizations, hospitals, and professional associations often share information on their websites.
- Various types of publications, such as government documents, reports, fact sheets, and theses or dissertations, can be used to find research evidence.
