Comparison of search strategies on CD Plus/MEDLINE.

OBJECTIVE: To compare two strategies for searching MEDLINE using the CD Plus/MEDLINE program on compact disc. DESIGN: Comparison study. INTERVENTIONS: Two search strategies were designed and executed for each of two topics (patient recruitment to clinical trials and attitudes of patients, the public and health care professionals toward clinical trials). Strategy A: searches based on key words selected from the medical subject heading (MeSH) tree structure. Strategy B: searches based on MeSH terms most frequently used to index a known set of relevant articles. Defined search restrictions were then applied. The effects of the restrictions on the absolute number of citations retrieved and on the proportion of relevant citations were assessed. OUTCOME MEASURES: Number of articles retrieved, number of relevant articles, precision and recall of each search strategy and overlap between strategies. MAIN RESULTS: Strategy A produced more citations than strategy B (recruitment 147 v. 38, attitude 366 v. 57) but had more inappropriate citations (recruitment 75 v. 17, attitude 265 v. 25). Both strategies produced 73 relevant recruitment citations and 101 relevant attitude citations. In the recruitment search although the precision did not differ significantly between strategies A and B the difference in recall was significant (98.6% v. 28.8% respectively, p less than 0.0001). In the attitude search strategy A had a lower precision than strategy B (27.6% v. 56.1%, p less than 0.0001) but a much higher recall (100% v. 31.7%, p less than 0.0001). CONCLUSIONS: Strategy A would be more valuable to researchers doing extensive reviews, whereas strategy B would be useful for the busy clinician who simply wants a few appropriate references quickly and is willing to sacrifice comprehensive retrieval in the interest of efficiency.

Multimedia approach to dental education in the 21st century.

Today's technology allows educators to design and create tools that enable teachers and students to work with material from different sources and to attend courses at various sites. The personal computer represents perhaps the greatest boon to this movement by providing a vehicle for "user friendly," interactive, multimedia courseware. A discussion of that courseware, its development and implementation, is provided here.

[Digital library for archiving files of radiology and medical imaging].

The Conseil des Enseignants de Radiologie de France in collaboration with the Ilab-TSI company and Schering laboratories has developed a computer programme allowing the storage and consultation of radiological teaching files. This programme, developed on Macintosh from standard Hypercard and Quicktime applications, allows, in consultation mode, the multicriteria search and visualisation of selected radiological files. In the author mode, new files can be included after digitalizing the author's own images or after obtaining images from another image library. This programme, which allows juxtaposition of digitalised radiological files, is designed to be extremely open and can be easily combined with other computer-assisted teaching or computer-assisted presentation applications.

Choosing your path to MEDLINE.

Competing vendors package the seven million article citations in MEDLINE in many different ways. When the information inside is the same, how can you tell solid value from just another pretty interface? This article, one in a series on medical information technology, discusses points to consider before making a commitment.

[Photo Compact Disc: proposal for the electronic storage of images].

We applied the Photo-CD technology to create an electronic image file easy and quick to use to optimize the retrieval of medical images for teaching purposes. We digitized 1,500 slides of diagnostic examinations from the archive of our Institution: the corresponding electronic files were stored on Photo-CD disks. The data relevant to every image were collected and recorded with the help of a relational data-base program. Thus, each user could retrieve the suitable images from the optical disks by a multiple and flexible key-word search. We compared the use of the electronic archive with a traditional hand-based file with the help of 3 teachers committed to prepare a lesson containing 5 slides on different subjects. The use of the electronic image archive corresponded to markedly shorter searching and file updating times. We tried also to assess the capabilites of this filing procedure for image post-processing and for the build-up of self-assessment programs.
