DXplain, a decision support system developed at the Laboratory of Computer Science at the Massachusetts General Hospital, has the characteristics of both an electronic medical textbook and a medical reference system. In its reference or case analysis mode, DXplain accepts a set of clinical findings (signs, symptoms, laboratory data) to produce a ranked list of diagnoses which might explain (or be associated with) the clinical manifestations. DXplain provides justification for why each of these diseases might be considered, suggests what further clinical information would be useful to collect for each disease, and lists what clinical manifestations, if any, would be unusual or atypical for each of the specific diseases.

Best practice data is available for most healthcare decisions, but health IT teams are doing a lousy job of getting it to doctors, says Ascension Health informatics chief.
If Meaningful Use of electronic health records is ever going to fulfill its promise of better care at lower cost, clinical decision support (CDS) systems had better play a central role delivering relevant medical evidence to the point of care, according to one veteran informatics physician and patient safety advocate.
