why databases
Why databases
  • Properly indexed records
  • Databases (e.g. Medline) only index journals which meet certain criteria
  • You can create complex searches using keywords, language tools and limits (e.g. year or age limits)
  • You can save your searches on the database website to retrieve later
  • Accuracy...

  • Chung, Matthew ... [et al] – Safe Infant Sleep Recommendations on the Internet: Let’s Google It Journal of Pediatrics

http://www.jpeds.com/webfiles/images/journals/ympd/JPEDSChung-Moon.pdf

  • Used 13 key phrases and analysed the first 100 search results for each phrase

how to find journal articles
How to find journal articles

If you need to search for articles on a specific subject, use databases of journal references such as:

  • Medline
  • Embase
  • Web of Science

See the Key Databases for Health Sciences user guide

for information about the databases:

http://www.kcl.ac.uk/library/help/guides.aspx

plan your search
Plan your search
  • Before you search for information it is important to develop a search strategy
  • Create a focused question – if it’s too general you’ll get too many results, so make it more specific
  • Identify the key concepts & keywords
  • Identify any synonyms, alternative spellings etc
focus your question or topic
Focus your question or topic

Unfocused topic:

  • The use of sedation in dental treatment

Focused topic:

  • Is sedation preferable to general anaesthesia when providing dental treatment for primary age children?
select the key topics
Select the key topics
  • Dental treatment
  • Sedation
  • Conscious sedation
  • General anaesthesia

Age limit: Primary age children (approximately 4-11)

subject headings
Subject headings

Use subject heading where possible, e.g. in MEDLINE or Embase as it’s an effective way of searching

Applied to articles to provide a consistent vocabulary, e.g. cancer maps to the subject heading Neoplasm

Articles are tagged with subject headings that describe the topics within the article

Not all databases include subject headings, e.g. Web of Science

slide20
AND

Retrieves results containing only both terms

This search will find articles only if they contain BOTH terms

e.g. general anaesthetic AND sedation

Makes search more specific

slide21
OR

OR - any of the specified terms will be present

Use to describe the same topic using different keywords

e.g. general anaesthetic OR general anaesthesia

Makes search broader

free text searching
Free text searching
  • Free text, keyword, or ‘natural language’ searching
  • The strategy used for searching the web and any database
  • Finds results if the words you are searching for are present in:
    • article title
    • abstract
    • keywords
  • You will find an article if you use the same terminology as the author(s)
truncation
Truncation

Use the ‘truncation’ symbol – an asterisk* to find

alternative word endings:

wildcards
Wildcards

Use wildcards (?) to search for variations within a word

practical go to the web of science
Practical – go to the Web of Science
  • Repeat the search you did in Medline (demonstration)
find full text
Find full text

Finding full text

Electronically as ‘e-journals’

In print at King’s libraries

In print at other libraries (e.g. other UL colleges)

Document delivery – interlibrary loans

Look out for the SFX@King’s logo – link to full text

group exercise solve a clinical query
