Selecting Resources and Conducting the Search
In this step, you will locate the highest quality, relevant information from the medical literature to answer your question. To do this, you need to select the databases and journals you will use to find the answer to your question.
Some resources, such as the Cochrane databases are "prefiltered". This means that the authors of the database have already systematically reviewed the articles to make sure that they are relevant and of high quality. Other resources, such as PubMed and CINAHL, are "unfiltered". This means that you conduct a search based on your question and filter through the results yourself.
