ABSTRACT
A system of operative quantitative assessment of the status of patients with rheumatoid arthritis (RA), osteoarthrosis (OA), systemic lupus erythematosus (SLE) and systemic scleroderma (SSD) was developed using a mathematical model of discriminant analysis. Data contained in case histories of 120 patients with RA, 112 with OA, 106 with SLE and 63 with SSD were used to determine discriminant coefficients of linear discriminant equations of some functional systems: locomotor, cardiovascular, respiratory, renal, digestive, nervous, skin and subcutaneous fat, immunological as well as laboratory findings on disease standing. Knowing discriminant coefficients, one can determine an index in any values of functional indicators that characterize the status of one or another system in any phase of the treatment of a patient. The system can be used in practice in a rheumatological hospital using CM-1600 minicomputer.
