Development of Search Strategies

Formulate the question Break the question down to various concepts Find the right MeSH/thesaurus for each concept Combine various concepts using Boolean operators

(AND, OR, NOT) Apply limit options (language, subset, age,

publication type, major heading, subheading) Run the search Modify search strategies and rerun the search

Why Use Index Terms (MeSH)? MeSH headings are an efficient way to find

information on “concepts” or topics where authors use different language to discuss the same ideas.

Using MeSH improves precision and accuracy of subject searching.

Searching for words in the keyword indexes may not retrieve relevant articles.

Example: physical therapy

“Storytelling as therapy: implications for medicine.”

Abstract: Storytelling is an art developed during the beginning of human history, probably to teach the wisdom of generations past, including basic mental and physical health principles…

Locating MeSH - 1 Do a Title word search. e.g. - Treat* [ti] AND repetitive stress injur* [ti] - Change display format to “Citation” to see assigned MeSH for the concept.

Tips on PubMed Searching

Search field tags are available [ti] Forced phrase searching in quotes “” Explode is automatic Use truncation (*) to broaden your search

(e.g. child* => child, children, childbearing) Boolean operators processed left to right To find in-process citations: Use keyword search

and limit your search to last one year. Keyword search: looking for terms in the title,

MeSH and an abstract.

PubMed My NCBI

Save search strategies Provide automatic email updates Set up filters for specific research

papers, e.g. systematic reviews, meta-analysis

Highlight PubMed search words in your retrieval

My NCBI – registration & set-up

Free registration

Setting up filters for RCT and meta analysis

Select ‘Filters’ in the far left menu, and then select PubMed.

Select ‘Search’ and look up ‘randomized controlled trial’. Select Randomized Controlled Trial under the matching filters list and then check the ‘Add’ box to automatically add RCT as one of your filters.

Go back to ‘Search’ and repeat this with ‘meta analysis’.
