title: [Surveillance of hospital acquired pneumonia in Polish hospitals].
abstract: The aim of this work is to analyze epidemiology of hospital acquired infections in Polish hospitals, according to type and size of hospital.
  
  
  METHODS
  Data gathered between year 2002 and 2004 in the Active Nosocomial Infections Surveillance System, developed and conducted by Polish Society of Hospital Infections, were used in the analysis. Epidemiology of PNEU was described with the usage of cumulative incidence and incidence density rates.
  
  
  RESULTS
  The average cumulative incidence rate was 0.29%; incidence density rate: 0.41 per thousand, and incidence density among ventilated patients: 1.57 per thousand. Differences in morbidity detected in hospitals were statistically important only in hospitals of different size. Morbidity of PNEU in intensive care units was much higher than in other wards, and differences were statistically important.
  
  
  CONCLUSIONS
  PNEU and VAP epidemiology in Polish intensive care units indicates serious problems in hospital infections control: high values of morbidity in non-teaching ICUs reflect the huge risk of developing infections in Polish hospitals. Low rates in ICUs of teaching hospitals reflect lack of surveillance and detection of infections in such hospitals.
