Peer review is the process by which research is assessed for quality, relevancy, and accuracy. In a peer reviewed, or refereed journal, each manuscript submitted to the publisher is first reviewed anonymously by a group of experts - peers in the same field of study. These reviewers assess the quality of the research, the accuracy of the findings, and the relevancy of the research to the journal or profession.
Peer review is like quality control. You should be able to trust the scholarship of the research.

Most of the journals in Medline/PubMed are peer reviewed. Generally speaking, if you find a journal citation in Medline/PubMed you should be just fine. However, as you can see in the PubMed FAQ, there is no way to limit your results within the PubMed or the Medline on Ebsco interface to knock out the few publications that are not considered refereed titles.
