PubMed is much larger than CINAHL. Because most journals indexed in PubMed are peer reviewed, limiting your search to peer reviewed articles is not an option. However, with a little extra research, you can confirm that the journal the article appears in is peer reviewed.
1. Perform a search.
2. On the results page, click the "Limits" link below the search box.
3. In the Limits window, go to the "Dates" section, click the "Published in the Last" drop-down menu, and select how recently you want the articles to have been published.
4. Scroll down to the "Subsets" section and click checkbox next to "Nursing journals."
5. Scroll to the bottom of the page and click the "Search" button.
6. The limits you selected will be applied to your search. Your new results list will consist of articles published in nursing journals during the time period you specified. Note that the authors may or may not be nurses, but you can usually find out whether they are by doing a web search on the their name and institutional affiliation and looking for their bio.
7. You can usually confirm that the journal is peer reviewed by doing a web search on the journal title and looking at the journal's website.
