Summary
Background: Increased usage of MedlinePlus by Spanish-speakers was observed after introduction
of MedlinePlus in Spanish. This probably reflects increased usage of MEDLINE and PubMed
by those with greater fluency in the language in which it is presented; but this has
never been demonstrated in English speakers. Evidence that lack of English fluency
deters international healthcare personnel from using PubMed could support the use
of multi-language search tools like Babel-MeSH.
Objectives: This study aims to measure the effects of language fluency and other socioeconomic
factors on PubMed MEDLINE and MedlinePlus access by international users.
Methods: We retrospectively reviewed server pageviews of PubMed and MedlinePlus from various
periods of time, and analyzed them against country statistics on language fluency,
GDP, literacy rate, Internet usage, medical schools, and physicians per capita, to
determine whether they were associated.
Results: We found fluency in English to be positively associated with pageviews of PubMed
and MedlinePlus in countries with high literacy rates. Spanish was generally found
to be positively associated with pageviews of MedlinePlus en Español. The other parameters
also showed varying degrees of association with pageviews.
Conclusions: After adjusting for the other factors investigated in this study, language fluency
was a consistently significant predictor of the use of PubMed, MedlinePlus English
and MedlinePlus en Español. This study may support the need for multi-language search
tools and may increase access of health information resources from non-English speaking
countries.
