Systematic literature searching is an advanced, structured process and a consistent approach is important. 

The search will need to be thorough, using relevant keywords, Boolean operators and advanced searching techniques.

The whole process (including the search strategy itself) will usually need to be documented, so that it could be repeated by someone else. Therefore, when planning, it is helpful to keep a record of which databases you have searched, the terms which were used and some notes about what terms did and didn’t produce good results. There are some templates below which could help with this.

Your subject guide will point you towards the most appropriate databases to search for your subject area. You won’t need to use all of them, but, you will usually need to use at least two or three.  Which ones and how many will depend on your specific question and assessment.

Structured literature searching: full process (Discovery and online databases)

Systematic searching in Discovery

The video and slides below provides an introduction of how to carry out a systematic literature search using Discovery. The search terms used are based on a research topic. It goes through 4 main steps to finding information:

  1. Identifying keywords.
  2. Deciding where to search.
  3. Searching.
  4. Evaluating results.

Systematic searching in the online databases

The video and slides below show how to do an advanced systematic literature search in the CINAHL, Medline and PsycINFO databases. The search terms used are based on a research topic. It goes through 8 key steps to finding information:

  1. Thinking about your topic.
  2. Identifying key concepts and putting them into a framework (if needed).
  3. Thinking of alternative keywords (synonyms).
  4. Linking the keywords together using Boolean operators.
  5. Applying advanced search techniques such as truncation and phrase searching.
  6. Carrying out the search.
  7. Reviewing the results and applying limits.
  8. Saving the search.

Searching in PubMed and PEDro

PubMed

Medline (available via EBSCOhost) will cover a lot of the content within PubMed and offers the ability to do a more focused/structured search. It is also one of the main databases used in Systematic reviews. However, although both databases are very similar and will have a lot of duplicated content, there are some differences to be aware of, before you make your decision about whether to search them both or not.

PubMed is an interface used to search Medline but it does also have some additional biomedical content. PubMed citations come from:
1) MEDLINE indexed journals:
2) journals/manuscripts deposited in PMC
3) NCBI Bookshelf. 

 

If you limit your PubMed search to MeSH controlled vocabulary or the MEDLINE subset, you will see only MEDLINE citations in your results.

PEDro, the physiotherapy evidence database

PEDro is a free database of randomised controlled trials, systematic reviews and clinical practice guidelines in physiotherapy.

The guide below shows how to use Boolean operators and search techniques in this database and how to view the results.
