A Model For Evaluation Of Data In Health Care Systems

A model for the representation of data is discussed which incorporates information and decision theoretic aspects. Several computerized medical systems are used as examples for components of the model. Implications of each component are discussed with reference to empirical research and relevant material in the medical literature. The consequences of this model for health care are primarily in two areas: 1) future design of computerized medical information systems and diagnostic or consultation systems; and 2) optimal utilization of clinical resources, i.e., allocation of decision-making and manpower.
