Select databases

Finding evidence involves searching health databases. 

As no one database contains all the available health literature, it is important to widen your search. Depending on your topic, consider the following:

Pre-appraised/filtered databases

Several databases provide assessments of original studies as well as access to systematic reviews which help summarise the results from a number of studies. This is referred to as secondary literature.

Primary/Unfiltered databases

Contains original studies published in journals, often referred to as unfiltered or primary resources. Where available, searching these databases is more effective if you use a combination of keywords and subject headings (see 'database tutorials')
