PubMed MEDLINE National Center for Biotechnology Information

(NCBI) Approximately 14 million references to the

published journal literature 1950 (OLDMEDLINE) to present in one

database Incorporates all or part of CANCERLIT,

Why use MeSH? If you use two or more words in a keyword search

there is no guarantee that they will be linked.

MeSH headings are an efficient way to find information on “concepts” or topics where authors use different language to discuss the same ideas.

For example: Keyword search physical therapyMicroneedles and other physical methods for overcoming the stratum corneum barrier for cutaneous gene therapy.

11

When to use keyword search?

Recent publications (in process) Records supplied by publishers New phenomenon

12

Locating MeSH Do a Title word search; display results in Citation

format; identify MeSH

OR

Search the MeSH database Scope Note Subheadings Major Topics Explode

Clinical Queries Etiology Diagnosis Therapy Prognosis Clinical prediction guides

Example: 1. Studies on the treatment of chronic low back pain

2. Systematic reviews on the treatment of chronic low back pain

14

Clinical Queries: Clinical Studies treatment of chronic low back pain

15

Clinical Queries: Systematic Reviewsphysical therapy to treat chronic low back pain

16

Topic Search Technique Separate query into main search concepts Identify an appropriate MeSH term for each

concept

Combine search terms using boolean operators:AND, OR, NOT

Apply Limit options Refine search

Limit Options Language (English) Human or animal studies Dates Age groups (All child, adolescent, aged…) Publication types (Meta-Analysis, ROC, Review, Evaluation

studies…) Subsets (Core clinical journals…) Major concept
