Asking Searchable, Answerable Questions Using PICO Model
P patient I intervention C comparison O Outcomes
In African American female adolescents with hepatitis (P), what is the effect of acetaminophen (I) compared with ibuprofen (C) on liver function (O) ?

Development of Search Strategies
Formulate the question; Break your question into multiple concepts
Locate the proper MeSH/thesaurus for each concept; Use AND to connect different concepts;Use OR to connect similar concepts
Refine your searchToo Many? Apply limit options (language, subset, age, publication type, major heading, subheading)Too Few? Google Scholar, Scopus

My NCBI Features
Highlight PubMed search words in your retrieval
Set “Abstract” format on MyNCBI account to open the supplemental data (MeSH, PTs) Save searches and set up alerts Set up evidence-based filters (Make sure every student sets up filter for systematic reviews, RCT, meta analysis and practice guidelines in the class.)

PubMed Quick TipsWhen you get too many results, try these tips.
Use “quotation marks” to search on a phrase Use [tiab] to find a word/phrase in the title or the
abstract Use [ti] to find a word/phrase in the title Use * to find alternative endings (child*=> child,
children, childbearing) Use “LIMITS” (language, subsets, age, publication
types), subheadings and major headings to refine your search
Exercise: Find systematic reviews on obesity prevention programs for Hispanic populations

Find the Most Recent Studies
New studies not yet indexed

Finding Relevant MeSH TermsUse Medical Subject Headings to focus your search.
Tips: Do a title word search
probiotics [ti] AND "acute diarrhea" [ti] AND child* [ti]
acute disease [mh] AND diarrhea/therapy [mh] (ages: all child)
Exercise: What is the effect of probiotics in treating/preventing acute diarrhea
in children?

Search Tips:Narrow Your Search to Be More Focused
Use the MeSH database
Subheadings: nursing, prevention and control, therapy…nursing [Subheading] Links Used with diseases for nursing care and techniques in their management. It includes the nursing role in diagnostic, therapeutic, and preventive procedures.
Restrict Search to Major Topic headings only
Exercise: Systematic reviews on end-of-life care in pediatric cancer
patients (English articles)
Etiology, genetics, prevention and rehabilitation of cardiovascular diseases among elderly (major topics), English articles, published in the nursing and core clinical journals in the past 5 years

PubMed: Clinical Queries
Finding the highest levels of evidence: systematic reviews and meta-analyses faster and easier
Providing further analysis of randomized controlled trials
Exercise: Find systematic reviews on complementary care in
pediatric oncology

PubMed vs CINAHL
Overlap Controlled Vocabulary
MEDLINE: Uses MeSHCINAHL: Based on MeSH & unique nursing and allied health terms called CINAHL Subject Headings
Peer-Reviewed ArticlesMEDLINE: can’t easily identify peer-reviewed articles: CINAHL: can use peer-reviewed limiter or use journal subset: peer-reviewed to locate peer-reviewed articles
The Library and the Center for Knowledge Management
CINAHL Nursing theories (Nursing theory, nursing models,
theoretical)
Evidence-based Care Sheets
