摘要

BackgroundWhen searching for renal literature, nephrologists must choose between several different bibliographic databases. We compared the availability of renal clinical studies in six major bibliographic databases.MethodsWe gathered 151 renal systematic reviews, which collectively contained 2195 unique citations referencing primary studies in the form of journal articles, meeting articles or meeting abstracts published between 1963 and 2008. We searched for each citation in three subscription-free bibliographic databases (PubMed, Google Scholar and Scirus) and three subscription-based databases (EMBASE, Ovid-MEDLINE and ISI Web of Knowledge). For the subscription-free databases, we determined which full-text journal articles were available free of charge via links to the article source.ResultsThe proportion of journal articles contained within each of the six databases ranged from 96 to 97; results were similar for meeting articles. Availability of meeting abstracts was poor, ranging from 0 to 37 (P < 0.01) with ISI Web of Knowledge containing the largest proportion [37, 95 confidence interval (95 CI) 32-43]. Among the subscription-free databases, free access to full-text articles was highest in Google Scholar (38 free, 95 CI 36-41), and was only marginally higher (39) when all subscription-free databases were searched. After 2000, free access to full-text articles increased to 49.ConclusionsOver 99 of renal clinical journal articles are available in at least one major bibliographic database. Subscription-free databases provide free full-text access to almost half of the articles published after the year 2000, which may be of particular interest to clinicians in settings with limited access to subscription-based resources.
