Hepius' flow of use. The flowchart summarizes Hepius' structure and the diagnostic pathway that the student must follow to achieve the final diagnosis. Data gathering deals with the collection of anamnestic, physical, and instrumental data suitable for formulating likely diagnostic hypotheses. Data analysis refers to the differential diagnosis process. During data analysis, the student is asked to generate a diagnostic hypothesis by reasoning on the relationship between the gathered information and the single hypothesized diagnosis. This process is obtained by the binary analysis and the pattern analysis. This should train the learner to avoid ordering unnecessary tests. Selection of the final diagnosis ends the simulation.
