Example from EAL
Definition/Description
“Evidence-Based Dietetics Practice
is the use of systematically reviewed
scientific evidence in making food and
nutrition practice decisions
by integrating best available evidence with
professional expertise and client values to
improve outcomes.”
Revised by EBP Committee and approved by HOD Leadership January 2006
Why Evidence-based Practice?
• To improve patient outcomes
• To improve patient safety & the
quality & efficiency of practice
• To take advantage of the
“exploding” body of biomedical
knowledge
• Thousands of new research studies
appear every month

Evidence Analysis Process
Steps in ADA’s
Evidence Analysis Process
Steps in ADA’s
Evidence Analysis Process
1)
Formulate Questions.
Expert Workgroup defines questions and the analytical
framework; lists keywords for search terms, and
determines Inclusion / Exclusion Criteria for Literature
Review.
2)
Gather and Classify Evidence Reports
Lead Analyst conducts Literature Review for each
question; records information online in Search Plan &
Results. Work group approves list of included articles
for analysis.
Steps in ADA’s
Evidence Analysis Process
3)
Critically Appraise Each Report
Analysts critically review articles and create article
Worksheets that are reviewed by Lead Analysts and
expert workgroup.
4)
Write the Evidence Summary
Analysts and Lead Analysts complete Evidence
Summaries and Overview Tables that are reviewed
and approved by expert workgroup.
Steps in ADA’s
Evidence Analysis Process
5) Grade the Conclusion Statement
Workgroup members reach consensus on
a brief conclusion statement (the answer
to the evidence analysis question) and
assign a grade based on the strength and
quality of the evidence.
Next Steps

Publish online to the EAL
Question, Conclusion, Grade, Search Plan &
Results, Evidence Summary, Overview Table,
Article Worksheets, and Quality Checklists are
published online.

Position Papers and Guidelines
Published Evidence Analysis Questions are used in
ADA position papers and to support guideline
recommendations.
Example from EAL

Select Diseases and Conditions tab.
1. Select a project from list of Diseases & Conditions.
2. Choose a topic
Disorders of
Lipid Metabolism
(select project)
Macronutrients
(choose topic)
3. Choose a sub-topic - if needed
Trans-fatty acids
(sub-topic)
Question
What is the relationship between
diets high in trans fatty acids and
serum cholesterol levels?
Bibliography
for Topic
Conclusion Statement/Grade
“Mouse over” or click on Question
to see Conclusion & Grade
Trans-fatty acids raise total cholesterol
and LDL-C. Unlike saturated fatty
acids, trans-fatty acids do not increase
and may decrease HDL-C. Trans-fatty
acids increase the TC/HDL-C ratio in a
dose dependent manner. GRADE I
