title: Pneumonia associated with aspiration following stroke.
abstract: OBJECTIVE
  To determine the association between demonstrated aspiration and pneumonia in stroke patients.
  
  
  METHODS
  Chart review of 441 consecutive stroke patients admitted to a stroke rehabilitation unit within 4 months of their stroke over an 8-year period. Videofluoroscopic modified barium swallow (VMBS) was performed on all patients suspected of aspirating. In all patients, the presence or absence of pneumonia was noted.
  
  
  RESULTS
  Eighty-four of the 441 (19.0%) stroke patients transferred for rehabilitation demonstrated aspiration of thin liquids on VMBS. Twelve of the 441 (2.7%) developed pneumonia while in hospital, either in the acute or rehabilitation phases. The incidence of pneumonia among proven aspirators on VMBS was 10 of 84 (11.9%) patients. Two of the 357 (0.6%) patients who were presumed nonaspirators developed pneumonia. Brain stem and right hemispheric stroke patients had a higher incidence of pneumonia.
  
  
  CONCLUSIONS
  Pneumonia is an uncommon complication of stroke. However, approximately 12% of stroke rehabilitation patients diagnosed as aspirators on VMBS developed pneumonia, a 20-fold increase over presumed nonaspirators. VMBS is a potentially valuable tool in determining those patients at risk of aspiration pneumonia.
