PPICOS Questions Concepts P = Population | Species P = Problem Definition • 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 What accomplish? Measure? Improve? Affect? S = Study design RCT? Systematic review? Synonyms for Concepts Concepts Search terms P = Population P = Problem Dairy cattle I = Intervention ELISA OR enzyme linked immunosorbent assay C = Comparison Intervention Cft OR complement fixation test O = Clinical Outcome Johne’s disease OR paratuberculosis Define Search Limits Publication Date Language Type of document – review, RCT Age group Gender Geographic Location Select Appropriate Databases for Your Topic and Task Veterinary Medicine Interdisciplinary Veterinary Medicine Databases CAB Abstracts – vet med, agriculture PubMed | MEDLINE – vet med, human medicine Wildlife & Ecology Studies – wildlife Agricola – agriculture Google Scholar – background, scoping search Scopus – interdisciplinary, cited reference libguides.ucalgary.ca/vetmed 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 Content Comprehensive index of veterinary medicine journals* Indexes many vet medicine conference proceedings PubMed 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 Cattle Practice Livestock Science UK Vet: Livestock Equine Australian Equine Veterinarian Equine Veterinary Education Journal of Equine Science Journal of Equine Veterinary Science Exotics Exotic DVM Journal of Exotic Pet Medicine Swine Journal of Swine Health & Production Pig Journal Some Vet Med Journals in CAB not in PubMed Poultry Journal of Poultry Science Poultry International Public Health Journal of Veterinary Epidemiology Journal of Veterinary Public Health Wildlife European Journal of Wildlife Research Journal of Wildlife Health Journal of Wildlife Management Other Journal of Veterinary Cardiology Search Strategies Search Mechanics Boolean Operators AND, OR, NOT (see separate slide) Parentheses ( ) Enclose synonyms for a concept in parentheses Search boxes in CAB Abs Multi-Filed does tautomatically Exact phrase search Varies depending on database Many databases use quote marks “_” around a phrase Truncation Asterisk at end of word stem retrieves plurals, word variants - therap* retrieves therapy, therapist, therapeutic Boolean Operators AND OR NOT Connects concepts Connects synonyms or similar terms within a concept Excludes all records that contain the term after NOT Finds records with EITHER or BOTH search terms Narrows search Broadens search Dementia NOT Alzheimers Finds records with ALL search terms Narrows search Dementia AND treatment Dementia OR Alzheimers Use with care Broaden or Narrow your Search Concept Search Terms A AND Cft OR complement fixation test “AND” in a concept NARROWS search B elisa OR enzyme linked immunosorbent assay AND C AND “OR” in synonyms within a concept BROADENS search Johne’s disease OR paratuberculosis Strategies to Broaden Searches Reframe your question to make it broader Use broader search terms Remove the least important concept Add synonyms within a concept (Boolean OR) Use truncation in textword searches – therap* retrieves therapy, therapist, therapeutic Apply fewer, or no limits Use the Explode feature (only in CAB Abs, OVID MEDLINE) Strategies to Focus Searches Reframe your question to make it narrower Use more specific search terms Add another concept Use less/no synonyms within a concept Use less/no truncation in textword searches Apply more limits Do not use the Explode feature (only in CAB Abs, OVID MEDLINE) Subject Heading vs Keyword Searching Subject Heading Textword |Keyword What is searched? Search subject headings assigned by indexer Search 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 Mode Depends on Task PubMed Default Need a few good articles Topic covered by vet journals indexed in PubMed Not much time to search PubMed Clinical Queries Want 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 Advanced Need systematic or comprehensive search PubMed Default PubMed Clinical Queries Textword Search (OVID Multi-Field) CAB Abstracts CAB Abstracts Record Textword Search Multi-Field OVID Subject Heading Search (OVID Advanced) CAB Abstracts CAB Abstracts Record CAB Abstracts Record Subject Heading search (OVID Advanced Search) searches this part of record Purpose of Subject Headings Account for synonyms, plural, alternate spelling Increased Relevance Purpose of Subject Headings Use the Explode function Purpose of Subject Headings Retrieval of abstract, multi-faceted topics Subject Heading Search OVID Advanced Getting Full-Text Articles Print Email Save Search Results OVID Full-text Articles SFX SFX Citation linker Links database search results with full-text articles Indicates if item is available in print in UC Library Interlibrary loan link if UC Library not have online or print Interlibrary Loan Order articles UC Library does not have Journal articles desktop delivery 2-4 business days Must have email in library patron database Full-Text Article: Via Database SFX Link I Interlibrary Loan Link on SFX in Database Interlibrary Loan Login Interlibrary Loan Journal Request Reference Management Mendeley • Organize references online • Format bibliographies http://www.mendeley.com/ Veterinary Medicine E-books libguides.ucalgary.ca/vetmed Find Books tab Selected Veterinary Medicine Ebooks Need Help?
