Goals

Know where to find evidence-based nursing information

Know how to construct a basic search


A little history…

• 1972: Archie Cochrane publishes'Effectiveness and efficiency: random reflections on health services'

collective ignorance about the effects of health care

Professor Archibald Leman Cochrane, CBE FRCP FFCM, (1909 - 1988)

Where do I search for answers?

• Databases, e.g.:– PubMed

– CINAHL

– Cochrane Library

– PsycINFO (psychology)

– Sociological Abstracts (sociology)

• Full-text resources, e.g.:– Up-To-Date

– Society Guidelines

– Organization [nursing] Manuals

– Books


Universal Search Tips

• Opt for “Advanced Search” interface

• Start with a “title word” search if you have a broad topic or a “keyword” search for a narrow topic

• Use Subject Headings if available

• Always limit last

• Remember – less is more!

• Select output options: print, email, save for later, or export to RefWorks


PICOan acronym to help frame the research question

• Patient population

• Intervention/exposure

• Comparison

• Outcomes


A PICO question

• P: In African American female adolescents with

hepatitis

• I: what is the effect of acetaminophen

• C: compared with ibuprofen

• O: on liver function?


Boolean power

John Venn


ANDLocates all records containing BOTH terms

Narrows your search

herbicides AND tadpoles =


ORLocates all records containing EITHER term

Increases retrieval

Use for synonyms or related terms

tadpoles OR frogs =


NOTLocates all records containing ONLY the 1st term

Warning: May eliminate good results

herbicides NOT pesticides =


Boolean logic

AND reduces retrieval

OR increases retrieval

NOT eliminates selected data

• Use OR before AND in simple statements

• Nest terms with parentheses ( ) for complex statements


PubMed “MY NCBI”

• Your personal account for PubMed

• Use “My NCBI” to

– save your searches and data

– create alerts

– set display preferences, eg., search term highlighting, article abstracts, search filter links

PMID- 18537845VI - 63IP - 2DP - 2008 JulTI - School-based drama interventions in health promotion for children and adolescents: systematic review.PG - 116-31AB - AIM: The paper is a report of a review of the literature on the effects of school-based drama interventions in health

promotion for school-aged children and adolescents. BACKGROUND: Drama, theatre and role-playing methods are commonly used in health promotion programmes, but evidence of their effectiveness is limited. The educational drama approach and social cognitive theory is share the assumption that learning is based on self-reflection and interaction between environment and person. However, educational drama also emphasizes learning through the dialectics between actual and fictional contexts. DATA SOURCES: A search was carried out using 10 databases and hand searching for the period January 1990 to October 2006. METHODS: A Cochrane systematic review was conducted. RESULTS: Nine studies met the criteria for inclusion. Their topics included health behaviour (five studies), mental health (two) and social health (two). Actor-performed drama or theatre play followed by group activities was the intervention in five studies, and classroom drama in four studies. Four of the studies were randomized controlled trials and five were non-randomized controlled studies. Four reports gave the theory on which the intervention was based, and in eight studies at least some positive effects or changes were reported, mostly concerning knowledge and attitudes related to health behaviour. The diversity of designs and instruments limited comparisons. CONCLUSION: There is a need for well-designed and theory-based studies that address drama interventions in health promotion for children and families. The challenge is to find or develop a theory, which combines educational, drama and health theories with valid and reliable measurements to examine the effects of the intervention.

PubMed Tips:

• Automatic Term Mapping (ATM) search hierarchy

1. MeSH – searches for your terms plus finds MeSH equivalents

2. Journals

3. Authors

4. Breaks apart your terms & searches each separately

• Save “in process”, “as supplied by publisher”, etc. citations to your Clipboard before searching with MeSH or they will be lost

• ATM turned off when phrase searching with

– Quotation marks “health promotion”

– Truncation * health promot*
