Evaluating the options for developing databases to support research-based medicine at the NHS Centre for Reviews and...

The paper presents the results of a questionnaire survey and user interface review group experiments to determine the value and ease of use of the Database of Abstracts of Reviews of Effectiveness (DARE) and the NHS Economic Evaluations Database (NEED). The results are interpreted with other recent studies of the use of electronic databases, including the NHS Research Register User Requirements Specification. The study found that most frequent users of the DARE database tend to use the CD-ROM version. Librarians were found to have the greatest awareness of the databases, with relatively low levels of use by operational NHS Staff. Untrained users found the online databases difficult to access and had erroneous perceptions of the database content which were only realised when queries returned unexpected answers. Experienced users of online information systems tended to want more sophisticated search facilities than inexperienced users. Nearly all users in the review groups wanted to access the databases in conjunction with other information sources, such as the Cochrane Library, Medline and the ACP Journal Club, highlighting the need for cross organisational strategies for the dissemination of research-based information.
