Introduction:

Staphylococcus aureus is an important human pathogen that causes a wide range of clinical infections; It is one of the main causes of bacteremia, endocarditis, infectious, as well as musculoskeletal, skin infections and soft, pleuro-pulmonary tissues. Bacteremia is perhaps best described by S. aureus infection manifestation. Several studies have documented the prevalence, prognosis and outcome of bacteremia by S. aureus (SAB) in the industrialized regions of the world. However, many basic questions about the epidemiology of the SAB, particularly in non-industrialized regions of the world, remain unanswered.

Materials and methods:

It’s an observational, descriptive, study retrospective type made in the Hospital San Juan de Dios between the years from 2015 to 2017. The study objective is to describe, laboratory and clinical characteristics in patients who were documented a bacteremia by S. aureus in the period in question.

Results and conclusions:

The majority of patients are male, with higher incidence in patients older than 60 years. The average hospital stay was 43 days. Bacteraemia by S. aureus acquired in the hospital was the most frequent. 43.9% of patients present with severe sepsis or septic shock at the time of diagnosis. Skin and soft tissue infection is the most common associated infection. Document risk factors more important in developing a S. aureus bacteremia is prior hospitalization and surgery. Comorbidities most frequent associates are diabetes mellitus, hypertension, renal disease chronic. The invasion most frequent was the central venous catheter.
