Ask a Librarian

The second step in the "Evidence Based Process" is to obtain the best research literature.  To make sure you get the best research literature, ask a librarian affiliated with the Integris Medical Library to do a literature search for you!  E-mail, request a search on your topic (noting that you are working on an evidence based approach), and a Medical Librarian will contact you!

4 Steps of the Evidence-Based Process

The question must be explicitly defined before searching for the answer. For evaluating the effectiveness of an intervention, four questions should be considered: 1. What is the relevant patient population? 2. What intervention is being considered? 3. What is the comparison intervention or patient population? 4. What outcomes are of interest?
Most medical information is now rapidly accessible from computers and hand-held devices. However, skill is required to quickly find the desired information, while limiting irrelevant "noise." Different approaches are required depending on the reason for seeking the information - contact the INTEGRIS Medical Library for help searching the literature:

At the most basic, one should know how literature is ranked in terms of content:
Systematic reviews and meta-analyses – This type of literature is considered the top of the pyriamid of evidence as these items compare and sum up studies and literature from several sources.
Randomized controlled trials – Second in line as truely randomized, large trials can provide excellent data.
Observational studies – Considered level 3 as the evidence can be tainted by bias.

Evidence Based Practice/Medicine is not intended to replace clinical judgment. Individual patients should be cared for in light of the best available research evidence, but with care tailored to their individual circumstances, including genetic makeup, past and concurrent illnesses, health-related behaviors, and personal preferences. Several studies clearly demonstrate that many clinical decisions are not made based on the best research evidence or on relevant individual patient characteristics, but seem most consistent with the practice habits or practice style of the clinicians.
