A knowledge-based system for transfusion advice.

Abstract

A knowledge-based system has been designed for evaluating the appropriateness of transfusion of non-red blood cell blood components. The goal of the system is to assist the blood bank physician in quality assurance efforts by automatically identifying cases of inappropriate transfusion before the blood is issued. Evaluation of a working prototype system shows that it is indeed capable of serving this function. The system identifies and summarizes cases, but it leaves consultation, education, and decision making to the blood bank physician. Small "expert systems" such as this may find use in quality assurance activities throughout the laboratory.
