Search Smarter: Finding information for the Health Sciences: Search Smarter

A guide on how to find information for assignments and research in the Health arena.

Step 1 - Keywords

Step 1 - Identify the keywords/concepts in your research question

Keywords are the main words, concepts or phrases that outline what your topic is about.

Keywords/concepts are used to search:

  • The Library catalogue
  • Databases
  • The Internet

Step 4 - Limits

Step 4 - Apply limits to your search

Health databases have a fantastic range of limits you can apply to your search some include:

  • Date ranges (last 5-10 years)
  • Human studies (vs animal studies.  Medline covers Vet Science as well as human health)
  • Type of publication (review vs Clinical trial vs randomised trial etc.)
  • Male/female (where a disease may be carried by one sex but presents and effects the other)
  • Age of patient (treatment for a child vs a 40 year old vs an 80 year old may be different)
  • Language (article abstracts are in English but the full-text may be in a foreign language so choose english)

Step 2 - Synonyms

Step 2 - Identify possible synonyms

Synonyms are words that have the same meaning. Synonyms can be:

  • Different spellings of the same word eg. pediatrics or paediatrics
  • Same meanings but a different word eg. cancer OR tumor OR tumour OR neoplasm
  • The singular/plural form or different endings of the same word eg. splint OR splints OR splinting
  • Abbreviations eg. CVA OR cerebral vascular accident

To identify relevant synonyms use:

  • Thesauri
  • Dictionaries (JCU has an online dictionary collection available via Credo)
  • Encyclopedias
  • Talk to other people (lecturers, tutors, peer group)

Step 5 - Search Strategy

Step 5 - Formulate and execute your search strategy

Add your keywords and your synonyms together using Boolean terms

AND  allow us to narrow our search. 
example:  malaria AND mosquito*

OR broadens our search
example: obes* OR overweight OR "over weight"

NOT excludes a term we don't want
example: radiation NOT nuclear

Step 3 - Truncation and Phrasing

Step 3 - Identify truncation and phrase searching opportunities

Truncation

Uses a symbol (usually the asterisk *) to find different variations of the same word stem:

  • Therap* would find therapy, therapies and therapeutic 
  • Child* would find child, childs, children, childhood and childers
  • Rehab* would find rehab, rehabilitate, rehabilitated and rehabilitation

Phrase searching

When there is a concept that is a phrase, we use inverted commas ("  " ) to stop the words from being separated:

  • "Evidence based"
  • "physical therapy"
  • "physician assistant"
  • "World Health Organisation"

Step 6 - Evaluation

Step 6 - Evaluate your results to see if further refinement is required

After you have completed your search, look at the results.  Do they provide you with the sort of results you were expecting? If not why not? You may need to change your search to give a better result. 

If you find a couple of articles that help answer your topic, look at how that database describes them (subject headings/keywords).  they may provide some words you should add to your search.
