ABSTRACT
OBJECTIVE:
To document the epidemiology, causes, treatment and prognostic factors associated with mortality of patients with brain abscess in a tertiary medical center.METHODS:
Observational retrospective cohort study of patients with cerebral abscess admitted at a tertiary hospital during 13 years.RESULTS:
The case records of 71 patients admitted to a tertiary hospital between January 1992 and December 2005 and diagnosed of brain abscess were review. Brain abscess occurred at all ages, more frequently in men than in women. Fever, headache and altered mental status were common presenting symptoms. The most common site of infection was the frontal lobe (28 patients). Seventeen patients had multiple abscesses. Staphylococcal infection was seen most commonly. Computed tomography provided sufficient diagnostic information in all cases. Twenty six patients had early surgical drainage. Thirty four patients were admitted to the intensive care Unit (ICU). The overall mortality was 21% (15 patients), all of that related to the infection. Six patients died in ICU. More than 65 years of age (OR, 1.0; CI 95%, 1.0-1.1), medical treatment without surgery (OR, 8.9; CI 95%, 1.1-73.8), presence of multiple abscesses, (OR, 6.0; CI 95%, 1.0-34.9), immunosuppression (OR, 21.5; CI 95%, 2.9-157.2) and delay in starting antibiotherapy (OR, 1.5 per day of delay; CI 95%, 1.0-2.1) were independent predictors of in-hospital death.CONCLUSIONS:
In spite of improvement in diagnosis and treatment of patients with cerebral abscess, mortality is still high. Factors related to patient underlying diseases and the delay in the start an antibiotic treatment were associated with increased mortality (50% increase of mortality risk per day in the delay of starting antibiotherapy).
