A sequential protocol for the optimization of diagnostic procedures in hepatology

, : A sequential protocol for the optimization of diagnostic procedures in hepatology. Journal of Medical Systems 8(1-2): 73-85

The aim of this paper is to present a sequential protocol to be used in clinical practice for the detection of liver diseases, based on clinical history, physical examination, and laboratory investigation. The evaluation of the protocol efficacy was carried out on a sample of 288 subjects (92 normal, and 196 affected by various liver alterations) by comparing the obtained results with reference classifications independently performed on the basis of all available subject records (including many more laboratory tests than the ones used in the protocol). A cost-benefit analysis was also carried out, based on the resident population of Regione Piemonte, comparing the protocol with two other simpler ones. Results show that the proposed protocol allows a considerable reduction of costs, showing a high estimated efficacy for clinical use.
