A thorough review of the literature is the basis of all research and
evidence-based practice. A gold-standard efficient and exhaustive search strategy
is needed to ensure all relevant citations have been captured and that the search
performed is reproducible. The PubMed database comprises both the MEDLINE and
non-MEDLINE databases. MEDLINE-based search strategies are robust but capture
only 89% of the total available citations in PubMed. The remaining 11% include
the most recent and possibly relevant citations but are only searchable through
less efficient techniques. An effective search strategy must employ both the
MEDLINE and the non-MEDLINE portion of PubMed to ensure all studies have been
identified. The robust MEDLINE search strategies are used for the MEDLINE portion
of the search. Usage of the less robust strategies is then efficiently confined
to search only the remaining 11% of PubMed citations that have not been indexed
for MEDLINE. The current article offers step-by-step instructions for building
such a search exploring methods for the discovery of medical subject heading
(MeSH) terms to search MEDLINE, text-based methods for exploring the non-MEDLINE
database, information on the limitations of convenience algorithms such as the
"related citations feature," the strengths and pitfalls associated with commonly
used filters, the proper usage of Boolean operators to organize a master search
strategy, and instructions for automating that search through "MyNCBI" to receive
search query updates by email as new citations become available.
