Computer-aided decision support in clinical medicine.
This paper reviews the problems and prospects involved in providing computer-aided decision support in clinical medicine. First, the evaluation of medical innovation is discussed. It is suggested that there are three criteria by which an innovation may be judged, namely (1) a need for the innovation, (2) the ability of the innovation to fulfil that need and (3) the ability to do so without transgressing practical, ethical or legal boundaries. These problems are addressed in turn. The paper suggests, taking one area of clinical medicine as an example (acute abdominal pain) there is a clear need for decision support--since the area is not handled well by doctors in current practice. Evidence is adduced to suggest that the computer can provide decision support and do so without transgressing professional, ethical or legal boundaries. The obstacles to progress, which stand in the way of widespread implementation are briefly discussed. These are lack of medical terminology, poor man-machine interface and above all a lack of co-ordination. Finally, it is suggested that the most valuable facet of current systems is the discipline and precision in data collection they impose upon practicing doctors.
