摘要

AI/Coag is an interactive, knowledge based computer system which reports, analyzes and interprets clinical blood coagulation laboratory studies. The laboratory subsystem presently deals with six tests: platelet count, bleeding time, prothrombin time, activated partial thromboplastin time, thrombin time, and urea clot solubility. This subsystem returns a detailed analysis and interpretation of the test results. It also offers further information on specific aspects of the interpretation in the form of “Tell-Me-More” (TMM) items. Individual TMM items may be requested by the user during each interpretive session. Also available are the literature sources underlying the knowledge base, stored by the subsystem as “Tell-Me-Reference” (TMR) items. A second subsystem, under development, contains a detailed hemostasis history questionnaire, the answers from which will be analyzed in conjunction with results from the laboratory subsystem to provide a definitive interpretation or to suggest further laboratory tests.
