[Epidemiology of bronchopulmonary hospital infections].
Hospital acquired infections (HAI) represent one of the major problems, due to their elevated frequency and high number of fatal cases, in the control of infectious diseases. With the perspective to evaluate the incidence of bronchopulmonary infections and to determine their role as cause of death of hospitalized patients, as well as to identify the etiology and the associated risk factors, we have studied 105 autopsy cases of patients decreased in hospital. 37 patients had pneumonias, of which 48.6% were of hospital origin. Hospital pneumonia was responsible for death in 12.3% of the cases. The risk factors significantly associated with HAI were recognized to be the following: hospital recovery for a period longer than 10 days, and surgery. Among the etiologic agents isolated in HAI, there was a distinct prevalence in Gram-negative bacteria (55.5% of the samples), such as Pseudomonas aeruginosa, Klebsiella pneumoniae, Legionella pneumophila.
