High Accuracy of Call Triage Decision by Bayesian Network

摘要

A new call triage system, a key part of an emergency support system with a stochastic network model, is examined. Call triage is an operation that allows efficient choice of service grade and dispatching of a suitable rescue team service based on information obtained from a phone call. Call triage is now being tested in a few cities and is showing some benefit. However, there is the issue that if under-tri-age, in which the condition of the patient is underestimated, is eliminated, then the efficiency is degraded in the form of over-triage. In this report, in order to overcome the issue, a Bayesian network scheme is evaluated for a call triage system. The results of experiments with a real call triage data set show that the Bayesian network improves accuracy.
