Last modified at 4/25/2016 3:52 PM by Vladimir Prikazsky

The “Point prevalence survey of healthcare associated infections and antimicrobial use in European acute care hospitals” protocol adopts the following definition of Lower Respiratory Tract Infection other than pneumonia (LRI):

LRI-BRON: bronchitis, tracheobronchitis, bronchiolitis, tracheitis, without evidence of pneumonia.

Tracheobronchial infections must meet the following criteria:

  • Patient has no clinical or radiographic evidence of pneumonia


patient has at least two of the following signs or symptoms with no other recognised cause: fever (> 38 °C), cough, new or increased sputum production, rhonchi, wheezing and at least one of the following:

    • positive culture obtained by deep tracheal aspirate or bronchoscopy;
    • positive antigen test on respiratory secretions.

A chronic bronchitis in a patient with chronic lung disease must not be reported as an healthcare associated infection , unless there is evidence of an acute secondary infection, manifested by change in organism.


LRI-LUNG: other infections of the lower respiratory tract.

Other infections of the lower respiratory tract must meet at least one of the following criteria:

  • patient has organisms seen on smear or cultured from lung tissue or fluid, including pleural fluid;
  • patient has a lung abscess or empyema seen during a surgical operation or histopathologic examination;
  • patient has an abscess cavity seen on radiographic examination of lung.


A lung abscess or empyema without pneumonia must be reported as LRI-LUNG.
