SCALE OF OUTCOME PREDICTION IN PATIENTS WITH URGENT SURGICAL PATHOLOGY CONSIDERING IMMUNE STATUS INDICATORS

Objectives. To work out a surgical immune-associated factor evaluation scale (SIAFE) to predict the outcome in patients with urgent surgical pathology, to estimate its informativeness, sensitivity and specificity.
Methods. Training data consist of 440 patients (930 examinations). The control group consisted of 80 patients with diffuse peritonitis. To calculate the SIAFE indicators of patients’ condition and the characteristic of immune system organization clusters were used. The SIAFE scale considers severity of peritoneal inflammation, SAPS II score, CD20+ lymphocytes count, parities of CD25+, CD38+ and CD95+ lymphocytes and a distance from the immune status cluster centre.
Results. According to the results of the dispersive analysis, the SIAFE scale is more informative in comparison with traditionally used scales, permits to estimate probability of a lethal outcome statistically authentically. The ROC-analysis confirms high sensitivity and specificity, «excellent» characteristics (AUC=0,95) of SIAFE scale.
Conclusions. The basic advantage of SIAFE is its universality at the estimation of disease outcome prediction in patients with urgent surgical abdominal pathology in various terms from the moment of hospitalization.
