Literature searching for Medical and Dental Sciences

Activity 2: Planning

First, be clear about your topic.  Try writing out the title and breaking this down into key areas, using a template: description follows, then a screenshot of the template.

This example has the topic "Treatment of cancers using personalized medicine" and breaks this down into three separate columns.

  • Personalized medicine alternative terms stratified, individualized
  • Cancer has the synonym neoplasms
  • Treatment terms could be therapy, drug therapy, chemotherapy

Limits are at the bottom of the template.  Suggestions are:

  • Date range: last 5 years
  • Language: English
  • Material type: eg Review article.  This could also be: systematic reviews, or RCTs, for example
  • Other: could be age group such as 6-12 or all adult

Methodology - PICO

There are specific methodologies which you may hear about during your studies, such as PICO: Patient or problem, Intervention, Comparison or comparator, Outcome. An S may be added for Study type, or T for the timescale involved. 

These then can be applied to planning your search strategy.  

The National Library of Medicine in the USA has a template with spellcheckers for using PICO.

View this PICO tutorial from the Miner Library on YouTube, which has subtitles. This includes a brief search using PubMed: see Activity 3A for examples using Ovid Medline.

 

Activity 2: Search plan - Practical exercise

Now try to plan a search with your own topic: or choose one of the following:

1. Treatment of obesity by lifestyle

2. The use of statins for treating hypertension

3. Vaccination for influenza epidemics in the health service

4. Mass screening for breast cancer in the U.K. 

5. Oral hygiene and health promotion in low- and middle-income countries.

6. Root canal surgery and prevention of infection.

7. The role of the dental hygienist in preventing dental caries in children.

Methodology - SPIDER (+)

An alternative methodology, aimed at research which is more qualitative than quantitative, or involves mixed methods, is called SPIDER.  Typically: Sample, phenomenon of interest, design, evaluation, research type.  (Cooke, Smith and Booth, 2012).  Read the article below for more information: the abstract contains a good summary of SPIDER and PICO methods  (Cooke, Smith and Booth, 2012).

For a further summary of these and other methodologies, see How to conduct a literature review (Health Sciences) from Virgina Commonwealth University (2020).

Public Health

A useful contribution to methods of searching the literature for public health and related topics is published as a narrative review by Heath, Levay and Tuvey (2021).
