• bacteremia.

objective: to analyze mortality and associated factors in community-acquired bacteremia admitted to an internal medicine department. patient and methods: prospective study of bacteremia admitted in 1 year (may 1999-april 2000). we have collected demographic data, previous comorbid conditions, functional status, source of infection, complications, vital signs, laboratory values, apache ii and sofa scores, blood cultures, therapy and 28-day mortality. in bivariate analysis, we have used chi-square, student-t test and mann-whitney u as needed. significant variables have been introduced in a stepwise backward logistic regression model with mortality as the dependent variable. results: we have observed 115 episodes of bacteremia in 114 patients. the source of bacteremia was urinary tract in 57.4% episodes and the most common isolate was escherichia coli (54.4%). 28-day mortality was 15.3%. factors independently associated with mortality were septic shock (or 10.4), non-urinary source of bacteremia (or 9.3), apache ii score higher than 20 (or 5,5), and previous dependent functional status (or 4.8). conclusions: mortality risk factors were septic shock, non-urinary source of bacteremia, apache ii score and dependent functional status.
