[Preoperative information].
BACKGROUND
Many empirical studies have identified the quality and communication of patient information as a major weak point in the treatment process. Patient information can be made considerably more effective by multimedia communication of contents tailored to the patient's needs. Computer-based training (CBT) takes the multimedia presentation one step further.


METHODS
Using the Macromedia Director 8.5 authoring software, a multimedia system for pre-operative patient information was developed on CD-ROM for a limited area of oral and maxillofacial surgery. This information system was evaluated for quality assurance on the basis of a random sample of 85 patients in a test lasting about 20 min. Impressions were determined with regard to design features, motivation, understanding, the subjective communication of knowledge, the newly acquired competence and acceptance compared with other media (information leaflets, Internet, conventional information).


RESULTS
The analysis of the program test revealed a hugely positive assessment of the interactive program in respect of layout, functionality and design as well as in respect of structuring and the subjective understanding of the underlying complaint, therapy and potential complications. In a comparison with other information media such as information leaflets and the Internet, the program was rated just as good or better by over 70% of the respondents. Only conventional consultation with a doctor came off better in a direct comparison.


CONCLUSIONS
It was shown that the quality of preoperative patient information can be improved through multimedia presentation and that it would be sensible to make use of modern media for the purposes of giving patients graphic information.
