Evaluation of a Diagnostic Reasoning Program (DxR): Exploring Student Perceptions and Addressing Faculty Concerns

Abstract: Clinical reasoning is essentially a problem-solving process, in which medical students must learn to gather and interpret data, generate hypotheses and make decisions. To develop skills in problem-solving it is argued that students need more tools, rather than more answers (Masys, 1989). DxR is a computerised case series, in which students use 'doctor tools' to investigate a patient problem. This report describes a pilot evaluation of DxR in fourth year medicine at the University of Sydney. It addresses faculty concerns regarding the program, explores student perceptions, and looks at the capacity of the program to stimulate and support the development of clinical reasoning skills. It finally discusses possibilities for using DxR to support learning in medicine. Reviewers: Stig Andersen (Virtual Centre for Health Informatics, Aalborg, DK), David Good (U.
