ResultsThe average difficulty of non-integrated items was (0.589±0.240), and of integrated items was (0.673±0.204), which indicated no significant difference was found (P=0.172). The average discrimination of non-integrated items was (0.237±0.125) and of integrated items was (0.299±0.092), which indicated significant difference(P=0.045).
ConclusionsUpon the results of examination , there was no significant difference of difficulties between non-integrated and integrated items for the same knowledge point, but the discrimination of the integrated items was obviously better than that of the non-integrated items.The application of integrated items in the medical licensing examination reveals the practical characteristic of clinical medicine, demonstrates the concept of competency-based medical education.
