ABSTRACT
Staphylococcus aureus bacteraemia is a serious and highly fatal infection. No published information on this condition in our country, so knowing its characteristics is very important. This is a retrospective, observational, descriptive epidemiological study type, held in Mexico Hospital in 2009 and included 72 patients older than 12 years. The incidence was 2.6 cases per 100 admissions. There was no difference in gender distribution, average age 52 years and 67% of patients had less than 60 years. Most affected (67 % ) suffered from 3 or more associated diseases , the most common: chronic renal failure ( 42 % ), diabetes mellitus ( 35 % ) , heart disease ( 24%) and malignancies ( 18%). Risk factors included central venous catheter (36%), dialysis (36%) and surgery in the previous 30 days (26%). The third part acquired the infection in the community, the rest of the cases relate to health care. Methicillin -resistant S. aureus (MRSA ) was responsible for 58 % of episodes of bacteremia . About half of the patients had severe forms of infection such as severe sepsis and septic shock. 60% of episodes of MRSA bacteremia received inappropriate initial treatment but 85 % was treated with an appropriate scheme available once the antibiogram. This did not occur in cases of MSSA bacteraemia where most deal with a useful scheme. Patients treated with inappropriate initial scheme had a high mortality and most died in the first 6 days of bacteremia. Other sites simultaneously S. aureus infections were present in 42% of cases. Mortality at 30 days of bacteremia was 39 % but the risk of dying from this condition was significantly greater when treatment was inadequate or the patient was over 60 years.REFERENCES
