  2. Sepsis was diagnosed in 119 out of 1638 persons (in 106 patients till the end of 2016 according to the older definition and in 13 since the beginning of 2017, according to the latest one). In the whole studied group, 108 persons died, 23 of them ICD -10 code for sepsis was assigned. In univariate and multivariate logistic regression analysis, the diagnosis of sepsis increased the risk of death fourfold.
