Disease Classification/Diagnosis Criteria

摘要: Well formulated diagnostic/classification criteria are important when one deals with diseases of unknown origin especially if specific histologic, radiologic or laboratory findings not available. On the other hand, usual separation classification and diagnostic is ill advised. When critically analyses current for rheumatic sees that they always promise to come. This, however, almost never happens. The mental/arithmetic process in either case, its pretest probability, sensitivity specificity, identical. A diagnosis, essence, nothing more than individual patient. Another common thought barrier formulating classification/diagnostic trying avoid circularity while making is, by definition, circular. By preparing a set, we carefully build up construct then decide whether what observe fits construct. Good examples these barriers can be found discussions about preparation implementation Behcet’s disease rheumatoid arthritis.
