• how to clarify the question(s) on which you need to
find literature
• selecting the databases and other resources you
will need to search
• devising the most comprehensive literature search
strategy so you know you’ve not missed any relevant
studies
• keeping up to date with new information appearing
between the initial search and write-up
• issues around management of process and results
• management of references (using software such as
RefMan), and getting hold of the full text article

Advice to rest in bed versus advice to stay active for acute
low-back pain and sciatica
The objective of this review is to determine the effects of advice to rest in bed or stay active for patients
with acute low-back pain or sciatica.
The following comparisons will be made:
• Bed rest versus staying active
• Bed rest versus other treatments (besides staying active)
• Shorter periods of bed rest versus longer periods of bed rest
• Staying active versus other treatments (besides bed rest)
• Comparison between different forms of advice to stay active (e.g. avoiding bedrest, staying active)

• Where will you record it? Where will you store it?
• How will you record it?
• How will you share it?
When should all this start?

Searching – Do’s & Don’ts
• Don’t try to do the whole search in one line
• Don’t imagine that your first attempt will get all the articles you need
• Don’t give up!

32. CAMBRIDGE UNIVERSITY LIBRARY

Searching – Do’s & Don’ts
• Do think of alternative ways of talking about your topic
• Do learn from your hits and your misses
• Do remember that you still have to critically appraise each article
• Do ask for help
