✦ Synopsis

Background: A questionnaire was developed to investigate the differences in frequency of usage and the understood meaning of 10 terms used in evidencebased medicine. Method: The questionnaire was administered to a group of healthcare professionals (64), medical students (71) and patients with diabetes (69). The frequency of use on a yes/no basis and a profile of usage by participants choosing alternatives a-d were recorded. Results: The findings showed that significant differences in the frequency of usage of terms such as 'risk factor' and 'relative risk' and the concept of 'number needed to treat' occurred between the three participant groups (p<0.001). The findings also showed that the considered meaning out of the four options offered for some of these 'terms' differed significantly between the three participant groups, eg 'probable' and 'risk factor' (p<0.001).

Conclusion:

We should be aware of the frequency with which we use these words and the meanings attached to them, both from our own and our patients' perspectives, and clarify this. We propose that further investigation is warranted.
