title: [Prevalence of nosocomial infections in University Hospital of Habana].
abstract: OBJECTIVE
  Determine nosocomial infection (NI) prevalence in seven University Hospitals of Havana.
  
  
  METHODS
  A cross sectional survey was carry out in university hospital with more than 100 beds. Presence of NI was determined by an active screening procedure in all patients admitted in hospitals. Technical statistics of frequency distribution was used. Rates of NI were estimated for each hospital and in the special case of procedure, Odds Ratio and its confidence interval at 95 % were calculated (CI 95 %).
  
  
  RESULTS
  Prevalence of NI was 9.2 %. The most frequent localization were: cardiovascular system (55 patients), surgical site (50 patients) and urinary tract (42 patients ). The 19.7 % of studied patient showed intravascular device. All patients showed NI associated with procedures, the highest intensity was association with an endotracheal tube (OR 7.83, IC 95 % 3.32-11.52).
  
  
  CONCLUSIONS
  Nosocomial infections in this hospital is a serious health problem; it is necessary to focus our medical work in this regard for the prevention and control of NI.
