Searching for quality information: using Discovery and the online databases

Finding Quality Information Part 1_Searching Discovery

Part 1 of this video series looks at how to search for quality information using Discovery.

It covers the basics of searching and using Discovery to create a basic and advanced search. The advice given and the searching techniques can be applied to any health topic/discipline.

Finding Quality Information Part 2_Searching the Online Databases

Part 2 of this video series looks at searching for quality information in the subject databases. It covers advanced and structured searching in the online health databases. The advice given and the searching techniques can be applied to any health topic/discipline. 

If you haven’t already done so, you might also find it useful to watch part 1 which looks at the basics of searching and using Discovery.

Journal Articles

What are journals?

Journals

They are:

  • like magazines but of a scholarly nature
  • published at regular intervals with no predetermined end
  • contain articles on a variety of topics
  • the articles are written by different authors
  • sometimes they also contain reviews and other information
  • in printed and electronic formats

Why Should I use them?

  • journal time is much quicker than for a book
  • using information from journals will keep you up to date and informed of new developments in your subject
  • journals articles are more specific than books.  They give you more detailed information in a more scholarly and concise format
  • subject may not yet (or may never) be covered in books
  • quality research - academic reputation - peer reviewed.

What does peer reviewed mean?

  • Written by an academic, who is a specialist in the subject
  • Submitted to an editor, who then passes the work to other professionals or 'peers' for a critiques, the work is then passed back to the original writer for changes to be made before being published
  • Longer articles, heavily text based
  • Charts, tables, statistics and images
  • Properly referenced with a list of references at the end of the article.

Evidence Based Practice

What is Evidence Based Practice (EBP)?

Evidence Based Practice is about using the best available evidence on the effectiveness of healthcare interventions as a basis for professional decision making in practice.  The evidence from the research should be used in conjunction with clinician expertise and patient choice.

Levels of Evidence

Evidence comes in various forms, some more reliable than others, so it is important that clinical practice is based on the most dependable.  In order of decreasing scientific validity they are:

  • At least one systematic review
  • One or more well conducted randomised control trials of appropriate size
  • Well designed non-randomised trials
  • Well-designed non-experimental studies from more than one source
  • Opinions of respected authorities
  •  “Someone told me”

What is a Systematic Review?

A systematic review assesses the effectiveness of a healthcare intervention on a disease or illness by providing a scientific method of assessing research evidence.

Systematic Reviews take great care to find and locate all relevant research studies on a particular intervention.  Rigorous methods are used to limit bias in identifying or rejecting studies to be included in the Review.  Each study is assessed and the results of the individual studies are synthesised in an unbiased way and an impartial summary of the findings is presented.

One of the main sources of Systematic Reviews is the Cochrane Library Online

To find the research efficiently, the first step is to ask a well-designed clinical question based on the PICO, PIO or PEO formula. This formula provides a framework for you search strategy. 

PICO  (Quantitative)  PIO   (Quantitative)     PEO   (Qualitative)
 - Patient or Problem  - Patient or Problem  - Patient or Problem
 -  Intervention (drugs treatment or therapy)  - Intervention (drugs treatment or therapy)  E - Exposure

C - Comparison between the Interventions

(control and experiment)

(optional - if there is no comparison use PIO)

O - Outcome - the results of the trials O  - Outcomes (Themes)
O - Outcome - the results of the trials

Support for Searching the Literature for Evidence Based Practice

Need to Search Grey Literature

Grey literature is material which is not usually published through normal channels.  Examples of grey literature include: government reports, theses, conference papers and abstracts, discussion papers, newsletters, PowerPoint presentations, best practice documents, guidelines and protocols. 

The helpsheet below details the best sources to use to find grey literature in health.

The UK Health Security Agency have also compiled an index of grey literature and the link to this is below.

Inter Library Loans

Have you found a useful resource that we do not have access to?  The Inter Library Loan (ILL) service gives staff and students of Teesside University access to material not currently held by the Library. See the Inter Library Loan Guide for more information.
