OBJECTIVE: The objective of this study was to determine the prognostic factors in relationship to evolution to death of bacteremia-fungemia (BF) episodes occurred in 1986 and to compare them with the results obtained ten years later in 1996. PATIENTS AND METHODS: Prospective study of all BF episodes observed at Hospital Universitario La Princesa, Madrid, during the 1985-1986 and 1996-1997 periods. The same definitions were used for the two study periods. The univariate analysis of results was performed with the chi square test and variables with statistical significance with p < 0.10 in the multivariate analysis with the logistic regression model. RESULTS: A total of 984 episodes were analyzed. There was an increased incidence per 1,000 admissions from 23.58 to 28.44. A change in the relationship of nosocomial acquisition (55.5%-42.6%) to community-acquired episodes (44.1%-57.4%) and an increase in gram-positive organisms (39%-48.6%) compared with gram-negative organisms (53.4%-41.8%) was observed. The organisms recovered most frequently in both periods were Escherichia coli and coagulase-negative Staphylococcus. An overall decrease of mortality rate from 26.2% down to 15.9% (OR: 4.52) was noted. Independent factors with poor prognosis in the first period included age over 60 years (OR: 4.52), underlying disease (OR: 2.79; more than one OR: 6.53), respiratory source (OR: 3.86), DIC (OR: 4.79), hypotension (OR: 3.19); as for the second period, the corresponding independent factors included age > 60 years (OR: 6.48), nosocomial acquisition (OR: 2.62), DIC (OR: 18.7), hypotension (OR: 3.07), and inadequate surgical treatment (OR: 7.61). CONCLUSIONS: In the last ten years the incidence of BF episodes has increased. In contrast, mortality rate has decreased. Factors with poor prognosis, including age > 60, DIC, and hypotension, still persist.
