Background
The MEDLINE view of regions is decidedly geographical. The MEDLINE controlled vocabulary, MeSH, describes Europe as, “The continent north of AFRICA, west of ASIA and east of the ATLANTIC OCEAN.”
The exploded MeSH term exp Europe/ reflects this vast geographical expanse. However, there may be occasions where a narrower definition of a region is preferred. For example, “Europe and the UK”. In this real-life example, further qualification discussions established that “Europe”, for the purposes of the investigation, was understood to be the countries making up the European Union.
This Focused Search, presented here as a search block, consists of 4 search lines, the search expressions compacted into the paragraph format for ease of viewing. Line #1 represents the countries making up the EU, individually selected from the geographical classification as rendered by MeSH. Line #2 locates countries by their English name using free term searching in the .ti,ab,hw,kf, fields for Ovid MEDLINE. Line #3 on the other hand identifies nationalities by their English name or names using free term searching also in the .ti,ab,hw,kf, fields for Ovid MEDLINE. Line #4 combines the controlled vocabulary terms (#1) and the two free term searches (#2 plus #3) with the OR operator so as capture both MEDLINE indexed records as well as those not indexed or in the process of editorial review.
