Abstract
LEIVA RABELO, Yunior; CESPEDES CARDENAS, Jarvis; HERRERA CARTAYA, Carlos Enrique and CHAVIANO CARDENAS, Yailen. Poor prognostic factors in patients infected with Staphylococcus aureus who are admitted to intensive care units. Acta méd centro [online]. 2020, vol.14, n.3, pp. 313-329. Epub Sep 30, 2020.

Introduction:
there are biological pathogenic agents that, instead of establishing a symbiotic and harmonious relationship with the human organism, produce disease and can cause death.
Objective:
to determine the factors of bad prognosis in infections by Staphylococcus aureus.
Methods:
a descriptive and prospective study was carried out in the Intensive Care Unit of the Arnaldo Milián Castro Hospital from September 2016 to June 2018. 114 patients between 19 and 82 years old made up the study population and 82 patients were included in the sample. Theoretical, empirical and statistical methods were used in the development of the research.
Results:
advanced age, minimum inhibitory concentrations above 1mg/l, Sepsis Related Organ Failure Assessment scale with 12 or more points, APACHE II prognostic score over 20 points, initial presentation of clinical picture as septic shock, previous use of antibiotics, comorbidities such as diabetes mellitus, pneumonic lung infection, methicillin-resistant staphylococic variety, use of artificial mechanical ventilation and previous use of steroids were found as bad prognostic factors. The most common type of infection was pneumonia, followed by bacteremias and skin and soft tissue infection; nosocomial and extrahospital origin did not differ significantly.
Conclusions:
the type of Staphylococcus aureus most frequently isolated by means of bacterial cultures was methicillin-resistant. Prolonged stay in the ICU was not a bad prognostic factor.
