Searching the Literature Part 1: Studies

The "5S" levels of organisation of evidence from healthcare research.
(From Haynes, 2006)

I tend to focus on the bottom of the Pyramid with Studies, the foundation of everything else. I search PubMed, the National Library of Medicine(NLM) database of abstracts from 3900 journals. Sometimes your Attending will want you to read a "classic" study, with an unintelligible acronym. such as TROPHY, STAR, or HOPE, from the base of the Pyramid. I'm glad to help you track these down.

I like to see where info originates, in a librarian-geeky kind of way--an Attending might want this kind of foundational backstory at times, or at other times you need something efficient and relevant to everyday patient care.

A more manageable approach to searching PubMed for Clinical questions, is the Clinical Queries link(under Tools), which leads to a filter for Evidence-Based Studies, as well as Systematic Reviews within PubMed, incorporating the next layer of the Pyramid, Syntheses. More on this next time.
