Searching for Evidence on the Web: 5 Steps for Nursing Researchers
3. #1 Clarify the Topic&Create a Plan
4. Clarify the Topic Why do you care?
What do you already know, including other people who have done work in this area?
Consider using a stepwise process, e.g. PICO, to clarify your information needs & to create a question that can be answered
5. PICO Patient population: For which group do you need information?
Intervention (or Exposure): What medical event do you need to study the effect of?
Comparison: What is the evidence that the proposed intervention produces better or worse results than no intervention, or a different type of intervention?
Outcomes: What is the effect of the intervention?
6. Create a Plan Time Line
Outline
Background searches
Obtaining literature
Analysis/research
Writing
7. What can be “shared”? Literature searching: once you clarify your topic you can explain it to a librarian who can work with you & create a focused search
Sometimes this takes several iterations because you will discover new information and ideas.
You may need to revise your research question.
You need to think critically about the search.
8. Document Retrieval Your librarian can advise you as to the most efficient way you can get the documents you need
9. Use Your Valuable Time Wisely Learn to work with the librarian so that you spend your time thinking about your topic and doing the research.
Let the librarian spend the time searching and locating needed documents.
10. #2Search for Evidencein a Database
11. What is evidence-based practice? Evidence based medicine is the conscientious, explicit, and judicious use of current best evidence in making decisions about the care of individual patients.
The practice of evidence based medicine means integrating individual clinical expertise with the best available external clinical evidence from systematic research.
Sackett DL et al. Evidence based medicine: what it is and what it isn't. BMJ 1996 Jan 13; 312 (7023): 71-2. Evidence-based practice uses the results of scientific studies whenever possible and expert opinion and extensive experience when data are lacking.

July 14, 2004: U.S.House Appropriations Committee recommends that NIH provide free public access to research articles resulting from NIH-funded research.
The Report calls on NIH to offer access to authors' final manuscripts (as accepted for journal publication) and supplemental materials via PubMed Central six months after publication.
If the grantee used NIH funds to pay any publication charges (e.g., page or color charges, or fees for digital distribution), PMC access would be immediate.
The Report instructs NIH to inform the Committee by December 1, 2004 how it intends to implement the policy. Needs to pass in Senate…

BRITISH PARLIAMENTARY PANEL ENDORSES OPEN ACCESS TO SCIENTIFIC LITERATURE
By Lila Guterman of the Chronicle of Higher Education In a
much-anticipated report scheduled to be released today, the Science and
Technology Committee of Britain's House of Commons endorsed open access to
research results and criticized the scientific-publishing industry for the
escalating prices of its journals. The report comes just days after a U.S.
Congressional committee recommended requiring free access to papers based on
research financed by the National Institutes of Health (The Chronicle, July
19).
