NUR 7005 - Nursing Research and Evidence for Practice: Literature Search Help
A guide to help you locate the best evidence for clinical questions.
When searching for individual research studies in healthcare, PubMed and CINAHL should be used. Google and Google Scholar are NOT sufficient for doing a good literature search in health care, although you can use Google Scholar to supplement your searches in subject specific databases.
PubMed provides free access to the National Library of Medicine’s (NLM) premier database – MEDLINE. Content is citations and abstracts from national and international journals covering all aspects of biomedicine including allied health and other fields as they relate to medicine or healthcare.
Indexes psychology literature and related disciplines including psychiatry, medicine, nursing, pharmacology, cognitive science, and linguistics. Includes journals and book chapters. Use Historic PsycINFO to identify literature published as early as the 1920s. Links occur to full-text when available.
Wright State University does NOT currently subscribe to the Cochrane Library, so we cannot access current subscription-based content. However, the Cochrane Library is still searchable and PubMed still indexes Cochrane Reviews. Also, many Cochrane Reviews are available as open access. If you need a Cochrane Review that requires a subscription or fee, please contact your subject librarian.
"Cochrane Reviews (including updates) published in the CDSR, with the exception of gold open access articles, are free to view in the CDSR 12 months after publication. This applies only to those versions published with a new citation on or after 1 February 2013." See Inclusion in PubMed Central for Additional Information

CINAHL: Keyword Searching Using PICO (length: 2:43)
CINAHL: Broadening Your Search (length: 3:05)
OPTIONAL - CINAHL - MeSH/Subject Heading Searching from EBSCO Support (length: 3:32)
This video from EBSCO shows how to start searching CINAHL Subject Headings from scratch. It does not use a PICO question example, but you can use the same process to identify subject headings for any of the keyword elements of your PICO(T) question.
Training Course (from the NLM): Using PubMed in Evidence-Based Practice
When conducting research, evidence-based practice is a method for framing clinical questions that will help yield optimal search results. PubMed is a free research tool from the National Library of Medicine®. This course will show you how to use evidence-based practice when searching clinical questions using PubMed®.
Note: To search PubMed®, please use Wright State's link for PubMed rather than the PubMed.gov® URL. This will ensure that you can access WSU and OhioLINK subscriptions to full text articles.
The scenarios used in this tutorial are geared toward nurses, but the tips for how to develop search strategies can transfer to any clinical scenario.

OPTIONAL - Use MeSH to Build a Better PubMed Query (from NCBI)
This National Center for Biotechnology Information (NCBI) video demonstrates how to build a search from scratch using MeSH. Although it is not a search on a PICO(T) question, the same process can be used to determine if there are relevant Medical Subject Headings for your population, intervention, comparison, and/or outcome.
