[Virtual room of gastroenterology].

The amount of published information and its continuing growth can no longer be managed by an individual searcher. One of today's great challenges for the academic researcher and clinician is to find a relevant scientific article using bibliographic search strategies. We aimed to design and build a Virtual Room of Gastroenterology (VRG) generating real-time automated search strategies and producing bibliographic and full text search results. These results update and complement with the latest evidence the Clinical Guideline Program of the World Gastroenterology Organisation. The HTML driven interface provides a series of pre-formulated MeSH based search strategies for each Aula. For each topic between 10 and 20 specific terms, qualifiers and subheadings are identified. The functionality of the VRG is based on the PubMed's characteristic that allows a search strategy to be captured as a web address. The VRG is available in Spanish and English, and the access is free. There are 28 rooms currently available. All together these rooms provide an advanced bibliographic access using more than 900 pre-programmed MeSH driven strategies. In a further very recent development some of the topics of VRG now allow cascade based searches. These searches look at resource sensitive options and possible ethnic difference per topic. The VRG allows significant reductions in time required to design and carry out complex bibliographic searches in the areas of gastroenterology, hepatology and endoscopy. The system updates automatically in real-time thus ensuring the currency of the results.
