Literature Search Process
Define your search question• Identify key concepts• Identify synonyms for each concept
Identify limits - language, publication date, etc
Select relevant database(s) to search
Create search strategy for the database
Literature Search Process
Run your search• Subject headings or Textword terms• Limit search
Evaluate results, revise search• Broaden• Focus• Choose a different database
Print, email, save results
Ask a SearchableQuestion
Among dairy cattle, is the complement fixation test vs the Elisa test more accurate in screening for Johne’s disease?
PPICOS QuestionsConcepts Definition
P = Population | Species P = Problem • Disease, condition
• Presenting symptom
I = Intervention • Treatment• Adverse drug reaction• Diagnostic or screening test• Environmental exposure
C = Comparison Intervention Alternative intervention – gold standard treatment, diagnostic test
O = Clinical Outcome
S = Study design
What accomplish? Measure? Improve? Affect?
RCT? Systematic review?

A Cautionary Note
PubMed & CAB Abstracts ….
• Not designed as clinical decision resources
• Not work like Google
• Quality varies - indexing, search functionality
• Effort to learn search skills > quality of results
CAB Abs vs PubMed
CAB Abstracts PubMed
Content Comprehensive index of veterinary medicine journals*
Indexes many vet medicine conference proceedings
Indexes 110 vet med journals + human medicine journals
Not index conference proceedings
Quality of Indexing Less depth, less consistency than PubMed
Consistent, in-depth, granular indexing
Search interface More complex than PubMed Easier, more intuitive
Evidence-based medicine
No Clinical Queries Clinical Queries feature
Access Subscription required Free
Some Vet Med Journals in CAB not in PubMed
Bovine Bovine Practitioner

UK Vet: Livestock
Equine Australian Equine Veterinarian
Equine Veterinary Education
Journal of Equine Science

Search Mechanics
Boolean OperatorsAND, OR, NOT (see separate slide)
Parentheses ( )Enclose synonyms for a concept in parenthesesSearch boxes in CAB Abs Multi-Filed does tautomatically
Exact phrase searchVaries depending on databaseMany databases use quote marks “_” around a phrase
TruncationAsterisk at end of word stem retrieves plurals, word
variants - therap* retrieves therapy, therapist, therapeutic
Boolean Operators
ANDConnects concepts
Finds records with ALL search terms
Narrows search
Dementia AND treatment
ORConnects synonyms or similar terms within a concept
Finds records with EITHER or BOTH search terms
Broadens search
Dementia OR Alzheimers
NOTExcludes all records that contain the term after NOT
Narrows search
Use with care
Dementia NOT Alzheimers
Broaden or Narrow your Search
Concept Search TermsA AND Cft OR complement fixation test
“AND” in a concept NARROWS search
B
AND
elisa OR enzyme linked immunosorbent assay“OR” in synonyms within a concept BROADENS search
C AND Johne’s disease OR paratuberculosis
Strategies to Broaden Searches
Reframe your question to make it broaderUse broader search termsRemove the least important concept Add synonyms within a concept (Boolean OR)Use truncation in textword searches – therap*
retrieves therapy, therapist, therapeuticApply fewer, or no limitsUse the Explode feature
(only in CAB Abs, OVID MEDLINE)
Strategies to Focus Searches
Reframe your question to make it narrowerUse more specific search termsAdd another concept Use less/no synonyms within a conceptUse less/no truncation in textword searchesApply more limitsDo not use the Explode feature
(only in CAB Abs, OVID MEDLINE)
Subject Heading vs Keyword Searching
Subject Heading Textword |KeywordWhat is searched? Search subject headings
assigned by indexerSearch word(s) in title, abstract
Advantages Retrieves more relevant results
Retrieves new topics in literature + very specific topics
Enables use of Explode feature
Easier to learn and use
Enables retrieval abstract, multi-faceted concepts
Disadvantages New terms (eg. New drugs) may not be in subject headings yet
Often retrieves more irrelevant records (word match)
Searcher must include synonyms, plurals, spelling variations in strategy
Search ModeDepends on Task
PubMed DefaultNeed a few good articlesTopic covered by vet journals indexed in PubMedNot much time to search
PubMed Clinical QueriesWant articles from top levels of evidence hierarchy
CAB Abs Multi-Field• Topic not covered in PubMed journals• Need a few good articles • Your topic has precise concepts & terminology
CAB Abs AdvancedNeed systematic or comprehensive search
