1. The method of operating a programmed automatic electronic computer to designate appropriate medical treatment for a patient who has been examined to determine each medical finding out of a predetermined set of medical findings which is present in the patient, the computer being adapted to have loaded therein and to read a readily interchangeable mass memory unit, said computer also including an entry unit and an output display system, said method comprising the steps of:

  • (a) loading the computer with a preprepared, readily interchangeable mass memory unit having stored therein signals representing the definitions of a plurality of disease entities, each disease entity definition including signals representing a plurality of corresponding selected disease codes, each corresponding selected disease code representing one out of the predetermined set of possible medical findings with respect to any patient'"'"'s condition, and also including signals representing a plurality of logic codes which, together with the selected disease codes, designate a corresponding logical combination of the selected individual disease codes which defines the disease entity, said mass memory unit also having stored therein, for each disease entity definition, corresponding signals representing at least one corresponding treatment code representing an appropriate medical treatment to be given to any patient whose medical condition satisfies the disease entity definition;

    (b) for each one of the predetermined set of medical findings found in the patient being treated, operating the entry unit of the computer to enter and to store in the computer electrical signals representing the corresponding disease code, whereby the stored patient disease codes represent the medical condition of the patient being treated;

    (c) operating the computer to read the contents of the mass memory unit and to respond to the logic code signals and selected disease code signals of each disease entity definition to perform a corresponding logical testing of the stored patient disease codes to test and indicate if they satisfy the corresponding logical combination of selected disease codes of the disease entity and, for each of the disease entity definitions whose logical combination of selected disease codes is satisfied by the stored patient disease codes, display indicia representative of the corresponding treatment codes;

    whereby the displayed indicia are representative of the treatment codes for all of the satisfied disease entity definitions.
