The final set of case vignettes is presented in Table 1.
Content validity of the case vignettes was established by review from physician medical editors of the online portal; editors represented the appropriate clinical area for each set of case vignettes.
That is, the constituent items can be scored following a standard clinical clerking, following a structured interview, based on a set of case notes, from a prepared case abstract/ vignette or from a combination of sources.
Based on the evidence and guidelines, a series of case vignettes were developed.
In order to explore the dimensions of the concerns raised we will use a series of case vignettes.
The classification of case vignettes into a clear-case vignette group and an ambiguous one was consistent with actual practice with sometimes vague presentations of disease pictures and diagnostic uncertainty.
Together with the use of case vignettes this may lead to a certain kind of fuzziness of data obtained.
Each of them received by post a different set of 10 case vignettes, selected so as to balance the number of clear and ambiguous cases, and varying the presentation order.
Raters at each site will be trained using a set of common vignettes developed from historical cases at each site.
