title: [Pseudomonas aeruginosa septicemia. Host-related risk factors in 82 episodes].
abstract: OBJECTIVE
  The prognosis of septicaemia due to Pseudomonas aeruginosa is severe with mortality ranging from 32 to 73%. We retrospectively studied 82 episodes in order to determine whether risk factors could be identified.
  
  
  METHODS
  Eighty-two episodes of Pseudomonas aeruginosa septicaemia, observed between 1986 and 1991, were analyzed. Risk of death within 2 days of the first positive blood culture (mortality = 19.5%) were assessed with univariate and multivariate analyses.
  
  
  RESULTS
  Patient age ranged from 1 to 92 years. Most had been hospitalized in medical wards (49%) or intensive care units (28%) (NS). The type of septicaemia (several bacteria in 21%), the source of the infection (nosocomial in 78%), portal, predisposing factors (cancer, haematologic disease: 54%) and MacCabe index were not significantly correlated with risk of death at two days following first positive blood culture. With univariate analysis body temperature below 38,5 degrees C was significant (p = 0.007) for death at day 2 and appropriate antibiotic treatment after diagnosis was significant (p < 0.001) for absence of death on day 2. For multivariate analysis, chemotherapy and shock syndrome were significant (p = 0.005 and 0.09 respectively) for death at day 2 and appropriate antibiotic treatment was significant (p = 0.005) for absence of death on day 2.
  
  
  CONCLUSIONS
  Antibiotic prescription appears to be the most easily controlled significant factor predictive of outcome in Pseudomonas aeruginosa septicaemia.
