12. Learning Objectives
To provide a mechanism for students to access the most current nutritional sciences and health care information
To familiarize students with specific information resources and services to support the nutritional sciences curriculum
To familiarize students with evidence-based health care and lifelong learning skills

13. Overview of Online Resources
Research and Clinical Databases
e-Journals
Evidence-Based Summaries

14. Journal Article Databases
Clinical Key (includes MEDLINE), CINAHL Complete, Science Direct, and UpToDate are most frequently used resources to find journal articles on nutritional sciences topics.
Search this section when you need articles on subjects, e.g., child nutrition disorders, diet therapy, etc.
Databases in this section provide links to full text journal articles and other resources
You must start at the library’s Nutritional Sciences web page to access our subscribed full text

15. Clinical Key
“All in one” database with full text access to 1,000 books and 500 journals in every medical and surgical specialty
Access to information at all levels from topic overview to evidence-based data in one search
Includes full text journal articles, book chapters, MEDLINE citations, videos, images, drug monographs
No complicated search strategies or Boolean connectors
View the brief video to get started
Easier than Google – but with reliable, evidence-based results

16. MEDLINE
U. S. National Library of Medicine’s premier database. Contains over 20 million citations to “journal articles” in medicine, nursing, allied health, and basic sciences as they relate to health care from 1946-present
Inclusion of a journal in MEDLINE is a quality measure. “Indexed for MEDLINE” denotes validation of journal legitimacy and quality.
The decision of whether or not to index a journal for this service is an important one and is made by the Director of the National Library of Medicine, based on considerations of both scientific policy and scientific quality. Over 5,600 titles are indexed and included in the MEDLINE database. The LSTRC meets three times a year to review journal applications.
Scientific merit of a journal's content is the primary consideration in selecting journals for indexing. The validity, importance, originality, and contribution to the coverage of the field of the overall contents of each title are the key factors considered in recommending a title for indexing, whatever the intended purpose and audience.

17. Databases - CINAHL Complete
CINAHL stands for Cumulative Index to Nursing and Allied Health Literature
Core research tool that contains full text of more than1,400 journals
Not all journals are peer reviewed. Limit search results to “academic journals”
Check the box next to “suggest subject terms” and search CINAHL headings for best results, e.g., search “pediatric obesity” for “childhood obesity”

18. Databases - CINAHL Complete

19. Databases – Science Direct
Scientific database produced by Elsevier
Provides journal articles from over 2,500 peer reviewed journals and chapters from almost 20,000 books in all life sciences disciplines
Useful to find full text articles on nutrition and dietetics topics in scientific journals across multiple disciplines
Contains full text of journals published by the American Academy of Nutrition and Dietetics

20. New Search Tools Target High-Quality Studies
MEDLINE - major source of “primary” literature, BUT
Process of searching, selecting, evaluating original research can be time consuming and requires critical appraisal skills
Filtered/Synthesized/Evaluated resources - “secondary” literature”, evidence summaries, e.g., UpToDate and First Consult
filter the journal literature and “point to” current studies of higher quality
include a formal system for grading the quality of the evidence and recommendations for practice
increase ease of accessing and understanding clinical research information

21. Evidence Summaries UptoDate
Evidence based summaries of over 10,000 topics in over 22 specialties
GRADE System used to score recommendations and strength of evidence
Practice changing updates; Updated continuously
Drug database; Patient education materials
The Gold Standard of summaries

22. Evidence Summaries FirstConsult Search online in Clinical Key
Concise summaries; sections on differential diagnosis and treatment (drug and non-drug)
quality of evidence graded and links included to relevant literature
Not updated as rapidly as UTD

23. Search Multiple Databases – Findings May Differ
