Abstract

PROBLEM TO BE SOLVED: To obtain a highly reliable clinical result by individually setting appropriateness check reference values in inspection abnormality check by the individual management method of previous value check in accordance with an internal medicine department, a rheumatic department and the like. SOLUTION: The measurement values of an object to be examined for respective inspection items are stored in a database storage part 14 with identification information of a person to be inspected, an inspection date, information by individual medical examination departments or information by individual ward departments. The appropriateness check reference values of the measurement values by individual medical examination departments or by the individual ward departments are set in an appropriateness check reference setting part by individual medical examination departments/ward departments 16 from the number of lapse days from the previous inspection date of the same examined person, and the measurement value belonging to the same medical examination department or the same ward department. Then, the appropriateness of the measurement values of this time is evaluated based on the number of inspection lapse days of the same inspected person and the appropriateness check reference values which are set by the individual medical examination departments or the individual wards by the appropriateness check reference setting part by individual medical examination departments/individual wards 16. Thus, the tendency for the respective medical examination departments or the respective wards of inspection result data by respective inspection items can be reflected on evaluation judgment, and the hit ratio of inspection can be improved.
