Introduction:

the term bacteremia is used to describe an infection characterized by the presence of bacteria in the blood, a phenomenon that is on the rise in intensive care units.

Objective:

to determine the prognostic factors of mortality rate in patients admitted with bacteremia in an Intensive Care Unit.

Methods:

an observational, analytical, and cross-sectional study was conducted at Dr. Carlos Juan Finlay Military Hospital in the period 2017-2019. Demographic, clinical, and epidemiological variables were studied in 130 patients. Descriptive and inferential statistics were used.

Results:

mean age was 61± 16,5 years, with predominance of male sex (53,8 %), parenteral nutrition (58,5 %), mono-microbial bacteremia (68,5 %), and secondary type (59,2 %). The main source was the central venous catheter (57,14 %) and Acinetobacter was isolated in 34,62 % of these patients; 58,5 % presented septic shock and 52,3 % died. In the multivariate analysis, age over ≥ 67 years old (OR= 4,82; CI: 1,32-17,63; p=0,018) and septic shock (OR= 28,2; CI: 7,72-102,96; p ˂ 0.001) were shown as predictors of mortality.

Conclusions:

bacteremia was more frequent in men, mainly in the elderly. The main risk factor was parenteral nutrition, and its main cause is gram-negative. Mono-microbial bacteremias are more frequent. It was determined that age over 65 years and the development of septic shock was predictive factors of mortality.
