Test diagnostic decision support software

Unaided: The testers will record a differential diagnosis consisting of a list of diseases and their ranking and a prioritized list of test orders, as well as the most appropriate referral for further evaluation and treatment of the patient.

Aided: Then testers will enter the case into diagnostic decision support software and after getting advice from the software, the testers will record the same information as in Unaided, but allowing for the possibility that responses could differ as a result of using the software.

Each clinician subject reviews each case vignette and lists their differential diagnosis ("Unaided").

Then the clinician subject uses the diagnostic decision support software and then lists a revised differential diagnosis ("Aided").

The match between the clinician subject's differential diagnosis and a Gold Standard differential diagnosis list for each case is measured, looking at rank order of correct diseases and omissions.
