Diagnostic criterion for the model of emergency medical diagnostics
The article is devoted to the methods of decision making in complex medical diagnostic situations with limited time. An activity of hospital admission department staff in the case of a seriously ill patient, who need emergency medical diagnostics, is analyzed. Diagnostic problems are investigated. The criteria system for an optimal choice of diagnostic information analysis algorithm is proposed. The model of diagnostic criterion in decision-making is formed. Last year, one of authors suggested a new choice mechanism for diagnostic information, based on the conception of information sources control. Two main problems connected with choice mechanism realization are the aggregation of criteria and, before, their formalization. The likelihood ratio is supposed to be the most effective formalization for the estimating of information, using for diagnoses. It is taken as a scale of diagnostic criterion. Usage this parameter with Bayesian approach allows to form an effective diagnostic algorithms. The development of this research direction is to choice preferred method of decision making in multi-criterion diagnostic field. Particularly, it is planned to apply the methods “Electra”, based on binary relations. These methods, in contrast to “aggregation”, account the value of local criteria and allow to use a fuzzy logic.
