Hierarchy of Evidence

A key concept for your literature review.

The purpose of a literature review is to identify the existing body of research that has addressed a problem and clarify the gaps in knowledge that require further research. 1

The term levels of evidence refers to what degree that information can be trusted. 1

Key Players: InternationalCochrane Collaboration

Systematic Reviews and

RCT’s

Evidence-based guidelines & summaries

• Developed by synthesising the highest level of evidence available on treatment choices

• Guidelines provide recommendations supported by that evidence

• May take into account resources and practices relevant to the organisation

• Concise and clinically relevant

Where do I find evidence?

• PubMed/MEDLINE and Embase

• Cochrane/JBI • DOSS – Dentistry

• TRIP/OvidMD

• BMJ Best Practice

• ClinicalKey

• UpToDate

• ETG Complete

See: Resources for Answering Clinical Questions

Guidelines and Protocols

Resources that aim to provide an overview of diagnosis, prevention and treatment of a specific conditions to be readily used by clinicians.

• Some claim to be evidence based (look for references)• Some are editorial based (professional backgrounds)

Guidelines: suggest current best practice but encourage further investigation by practioners of range of evidence given.

Protocols: Generally promoted as the core treatment method. Sometimes listed as Point of Care resource.

Activity• In groups of 4, go to one of the four resources for Evidence

Based Guidelines and look up “Gingivitis”

• Go the Resources for Answering Clinical Questions, UWA Resources Tab

Does brushing with fluoride toothpaste pose a risk to very young children?

Search string strategy:

concept 1 concept 2 concept 3

Key concepts brushing with fluoride toothpaste

Risk of young children

Keywords Fluoride toothpaste Risk/s children

SynonymsAlso related terms and variant spellings

Teeth brushing Danger/s ToddlersBabies

Does brushing with fluoride toothpaste pose a risk to very young children?

Search string strategy:

Boolean search techniques• Use AND to combine concepts (toothpaste AND fluoride)

• Decreases number of results

• Use OR to combine synonyms (child OR toddler)• Increases number of results

• Use NOT for subsets eg. (fluoride NOT Austral*)

• Truncation – usually the * will truncate words to their root• eg. Australi* will find australia, australian, etc

• Quotation marks – used for searching a phrase eg “tooth disease”• Question mark – often used as a wildcard symbol, eg. behavio?r• Brackets (nesting) – used to join synonyms (tooth OR teeth)

Key concepts brushing with fluoride toothpaste

Risk of young children

Keywords Fluoride toothpaste Risk/s children

SynonymsAlso related terms and variant spellings

Teeth brushing Danger/s ToddlersBabies

Does brushing with fluoride toothpaste pose a risk to very young children?

Search string strategy: “fluoride toothpaste” AND (child* OR toddler*) AND (risk OR danger*)

Activity• Break down the research question you have

been given

• Identify the key concepts

• Identify synonyms

• Build a search string applying booleans

• AND, OR, “##”, (###), ?, *

Medline or PubMed?

• See http://www.nlm.nih.gov/pubs/factsheets/dif_med_pub.html for a summary of the differences. PubMed is free, larger, and has greater currency.

• MedLine are all those items that have been selected for inclusion and indexed using MeSH terms. Greater control over search strategy in the Ovid interface.

PubMed search

Medline search

Build up your search concepts one at a time to make full use of MeSH terms and how you construct your search.
