A test selection module for MEDAS

A test selection module to recommend proper tests to the physician during the diagnostic process has been added to MEDAS (the Medical Emergency Decision Assistance System). Test selection is an important part of the diagnostic process. This module can use either diagnostic hypotheses set up by the physician or derive its own diagnostic hypotheses from the differential diagnosis. This module recommends pertinent questions to be asked about the patient's history and physical examination and recommends laboratory and radiological tests. The recommended tests are presented in two different ways: as individual tests and as groups of sequential tests.
