Computer-assisted test interpretation: considerations in patient care

Computer-assisted test interpretation (CATI) is a set of developing technologies designed to support medical decision-making. This paper develops a taxonomy of computer-assisted test interpretation, giving specific consideration to the characteristics of the data that are to be interpreted, the nature of the interpretive task, the expected involvement of the health professional in the generation of the interpretation, the inference mechanism used for the interpretation, and the broader context of the interpretation. We go on to examine potential benefits and disadvantages of CATI systems in terms of accuracy, information management, interpretation time, patient management, medical communication, and expense. Finally, we examine electrocardiogram interpretation systems from the perspective of this taxonomy, and offer suggestions regarding areas of further inquiry into the effects of CATI on medical care.
