Finding suitable evidence can be difficult. The databases are huge and sometimes article titles do not fully describe their content. A good search strategy can help you to identify relevant documents.
Avon Primary Care Research Collaborative, together with their local Academic Health Science Network and the NIHR, have put together a toolkit which you may find useful in finding, appraising and applying evidence.
You can find more information about this on the 'reading and understanding research findings' and 'recommended reading' sections of our repository.
